SUPPLEMENTARY INFORMATION:

Background

    It is our intent to discuss only those topics directly relevant to 
the designation of critical habitat for the California red-legged frog 
in this final rule. For more information on the California red-legged 
frog and threats affecting the species, refer to the final listing rule 
published in the Federal Register on May 23, 1996 (61 FR 25813) and the 
recovery plan for the species (Service 2002, pp. 1-173).

Change in Nomenclature

    When we made the draft economic analysis of the proposed revised 
critical habitat for the California red-legged frog available on April 
28, 2009 (74 FR 19184), we proposed a nomenclature change to the 
California red-legged frog from Rana aurora draytonii to Rana draytonii 
and for that change to be published in the Code of Federal Regulations 
(CFR) when this rule became final. In this rule, we make that change 
and will now refer to the California red-legged frog by its accepted 
taxonomic name of Rana draytonii.

Species Description

    The California red-legged frog is the largest native frog in the 
western United States. It is endemic (native and restricted) to 
California and Baja California, Mexico, at elevations ranging from sea 
level to approximately 5,000 feet (ft) (1,500 meters (m)). Records of 
the California red-legged frog are known from Riverside County to 
Mendocino County along the Coast Range; from Calaveras County to Butte 
County in the Sierra Nevada; and in Baja California, Mexico (Grismer 
2002, p. 79; Fidenci 2004, pp. 27-29; Smith and Krofta 2005, pp. 4, 6; 
California Natural Diversity Database 2009 (CNDDB)). The California 
red-legged frog gains its name from the typically red or pink color of 
its posterior abdomen and hind legs. For a detailed description of the 
species, see the recovery plan for the California red-legged frog 
(Service 2002, pp. 1-173), references identified in the recovery plan, 
and information in previous Federal Register notices (April 13, 2006, 
71 FR 19244; March 13, 2001, 66 FR 14626; May 23, 1996, 61 FR 25813).

Life History

    During the breeding season, which typically runs from November 
through April, males call to females from the margins of ponds and slow 
streams (Jennings et al. 1992, p. 3). Mating most commonly occurs in 
February or March, but can vary depending on seasonal climatic 
patterns. The female lays a jellylike mass of 2,000 to 5,000 reddish 
brown eggs in the water attached to emergent vegetation, twigs, or 
other structure. The resulting tadpoles, which likely feed on algae 
(Dickman, 1968, pp. 1189-1190), typically require about 3 weeks to 
hatch, and another 11 to 20 weeks to metamorphose into juvenile frogs. 
Metamorphosis, therefore, typically occurs from July to September, 
although some tadpoles have been observed to delay metamorphosis until 
the following March or April (Bobzien et al. 2000, p. 13; Fellers et 
al. 2001, pp. 156-157). Adults are predominantly nocturnal, while 
juveniles can be active at any time of day (Hayes and Tennant 1985, p. 
604).

Habitat

    California red-legged frogs live in a Mediterranean climate, which 
brings about temporal and spatial changes in habitat quality. Almost 
the entire landscape, not just breeding ponds and streams, may become 
suitable habitat for the adults during periods of above average 
rainfall. Conversely, habitat that is suitable may be drastically 
reduced during periods of prolonged drought. Due to this variability, 
population sizes can vary widely from year to year. During years when 
aquatic habitat (ponds and streams) is abundant as a result of adequate 
rainfall, the California red-legged frog can produce large numbers of 
dispersing young, resulting in an increase in the number of occupied 
sites. In contrast, the California red-legged frog may temporarily 
disappear from an area during periods of extended drought. Therefore, 
it is essential to provide for sites that can be recolonized by

[[Page 12817]]

dispersing individuals (Semlitsch 2000, pp. 623, 624).
    Habitats used by the California red-legged frog typically change in 
extent and suitability in response to the dynamic nature of floodplain 
and fluvial processes (i.e., variable natural water flow and 
sedimentation regimes that create, modify, and eliminate deep pools, 
backwater areas, ponds, marshes, and other aquatic habitats). 
Rangewide, and even within local populations, the California red-legged 
frog uses a variety of areas, including aquatic, riparian, and upland 
habitats. They may complete their entire life cycle in a particular 
habitat (e.g., a pond is suitable for all life stages), or they may 
seek multiple habitat types depending on climatic conditions or 
distance between and availability of wetland and other suitably moist 
environments.
    Despite the California red-legged frog's ability to utilize 
multiple habitat types, there are certain habitat features they 
require. Most important is a breeding pond, or slow-flowing stream 
reach or deep pool within a stream with vegetation or other material to 
which egg masses may be attached. These areas must hold water long 
enough for tadpoles to complete their metamorphosis into juvenile frogs 
that can survive outside of water. Bobzien et al. (2000, p. 12) 
observed juveniles inhabiting a wide variety of habitats while adults 
primarily inhabited deep pools. They postulated that juveniles might 
segregate themselves away from adults to escape predation and 
competition (see Dispersal section below).
    In northern California, many California red-legged frog populations 
occupy artificially created wetland environments. Historically, as 
natural wetlands and streams were converted for agriculture, flood 
control, and urban development, the California red-legged frog 
colonized small artificial impoundments, or stock ponds, created by 
cattle ranchers for the purpose of providing water for their cattle. 
Our understanding of the role of stock ponds in the conservation of the 
California red-legged frog has evolved since listing. Without these 
stock ponds, the range of the California red-legged frog would be more 
limited in this region.
    Riparian and upland habitats adjacent to aquatic areas used by the 
California red-legged frog are essential in maintaining frog 
populations, and for protecting the appropriate hydrological, physical, 
and water quality conditions of the aquatic areas. Riparian habitat 
includes vegetation that grows along banks and in the floodplains of 
streams and adjacent to ponds and that is dependent on the bordering 
water source for survival. Adjacent uplands are marked by vegetation 
that is not dependent on a nearby supply of surface water. The 
California red-legged frog uses both riparian and upland habitats for 
foraging, shelter, cover, and non-dispersal movement (Service 2002, pp. 
14-15; Bulger et al. 2003, p. 87; Fellers and Kleeman 2007, p. 276). 
Bulger et al. (2003, pp. 85-95) studied the California red-legged 
frog's terrestrial activity in coastal forest and grassland habitats 
and recommends at least a 328-ft (100-m) buffer zone for protection of 
adjacent aquatic and upland habitat, as well as seasonal restrictions 
for activities within this zone. In a recent study also specific to the 
California red-legged frog, Fellers and Kleeman (2007, pp. 278-280) 
recommend establishing zones around breeding habitat, non-breeding 
habitat, and migration corridors that are sufficient to protect 
function of the amphibian habitat. However, Fellers and Kleeman (2007, 
p. 279) discourage setting specific distances for these zones due to 
differences in biological or site-specific requirements; they further 
state that any distances set for avoidance of upland habitat should be 
made on a case-by-case basis, taking into account the need to protect 
breeding and non-breeding habitat as well as any migration corridors. 
Without protecting and maintaining the upland areas surrounding 
breeding and non-breeding habitats the quality of the water feature may 
deteriorate to such an extent as to not support the California red-
legged frog.
    California red-legged frogs will disperse from their breeding 
habitat to forage and seek suitable upland and riparian habitat if 
aquatic habitat is not available. Tatarian (2004, p. 33) found the 
California red-legged frog inhabiting upland areas for 50 days at a 
distance of 302 ft (92 m) from aquatic habitat; Bulger et al. (2003, p. 
87-89) found that the species is capable of inhabiting upland habitats 
within 200 ft (60 m) of aquatic habitat for continuous durations 
exceeding 20 days; and Rathbun et al. (1993, p. 15) observed a 
California red-legged frog inhabiting upland riparian habitat at 
distances of up to 85 ft (26 m) for 65 days. These upland habitat areas 
used by the California red-legged frog include structure that provides 
shade, moisture, and cooler temperatures. This structure may be 
natural, such as the spaces under boulders or rocks and organic debris 
(e.g., downed trees or logs), or manmade, such as certain industrial 
debris and agricultural features (e.g., drains, watering troughs, 
abandoned sheds, or stacks of hay or other vegetation). The California 
red-legged frog will also use small mammal burrows and moist leaf 
litter as refugia (areas whose climate remains habitable when that of 
the surrounding areas has changed) (Rathbun et al. 1993, p. 15; 
Jennings and Hayes 1994, p. 64; Fellers and Kleeman 2005, p. 12).

Metapopulation Dynamics

    The life history and ecology of the California red-legged frog make 
it likely that this species has a metapopulation structure (Hanski and 
Gilpin 1991, pp. 3-16). A metapopulation is a set of breeding sites 
within an area, where typical migration from one local occurrence or 
breeding site to other areas containing suitable habitat is possible, 
but not routine. Within this rule we refer to these local occurrences 
as populations. The movement (i.e., dispersal) of frogs between areas 
containing suitable upland and aquatic habitats is restricted due to 
inhospitable conditions around and between areas of suitable habitats. 
Because many of the areas of suitable habitats may be small and support 
small numbers of frogs, local extinction of these small populations may 
be common. The persistence of a metapopulation depends on the combined 
dynamics of these local extinctions and the subsequent recolonization 
of these areas through dispersal (Hanski and Gilpin 1991, pp. 3-16; 
Hanski 1994, pp. 151-162). Maintaining corridors for dispersal between 
breeding and non-breeding habitat and between populations is essential 
in preserving the population structure of the California red-legged 
frog.

Dispersal

    Adult California red-legged frogs may disperse from breeding sites 
at any time of year depending on habitat availability and the 
environmental conditions of the aquatic habitat. In addition, a few 
frogs may disperse long distances in search of additional breeding or 
non-breeding habitat. Dispersing adult California red-legged frogs in 
northern Santa Cruz County traveled distances of 0.25 mile (mi) (0.4 
kilometers (km)) to more than 2.0 mi (3.2 km) without apparent regard 
to topography, vegetation type, or riparian corridors (Bulger et al. 
2003, p. 90). California red-legged frogs have also been tracked using 
radio telemetry in East Las Virgenes Creek, Ventura County, which is 
characterized by a well-defined creek and riparian zone with permanent 
deep pools and highly variable rainfall (Smith 2005, p. 1). The maximum 
distance moved in this study was 48 ft (15 m) (Smith 2005, p. 1). In 
contrast, California red-legged frog

[[Page 12818]]

movements in Santa Cruz County in similar habitat were found to be 
substantially less, with typical movements of 9 to 16 ft (3 to 5 m) 
from the water's edge. In a study in Marin County, 123 California red-
legged frogs were tracked using radio telemetry between 1997 and 2003 
at 8 different sites within the Point Reyes National Seashore and 
Golden Gate National Recreation Area (Fellers and Kleeman 2007, p. 
277). The habitat at the sites included permanent ponds, seasonal 
ponds, permanent marsh, and a seasonal seep. The majority of movement 
was small scale (less than 98 ft (30 m)) and considered non-dispersal. 
Movements of greater than 98 ft (30 m) occurred mostly during winter 
rain events; however, some movements did occur when the ponded habitat 
was almost dry (Fellers and Kleeman 2007, p. 279). The majority of 
California red-legged frogs dispersed less than 1,640 ft (500 m) away 
from breeding habitat, and the maximum dispersal distance recorded was 
1.7 mi (2.8 km) (Fellers and Kleeman 2007, pp. 279-280). The study 
concluded that most California red-legged frogs move away from breeding 
sites, but only a few disperse farther than the nearest non-breeding 
habitat, and that the distance moved is highly dependent on site 
conditions and local landscapes (Fellers and Kleeman 2007, p. 284). The 
study also concluded that, by establishing a generic dispersal distance 
for the species, we may select for sedentary frogs and thus lose those 
individuals that disperse farthest and reach other distant breeding 
sites. This selection may thereby decrease genetic exchange and 
diversity (Fellers and Kleeman 2007, p. 285). As a result the authors 
recommend that the average dispersal or migration distances identified 
in the study not be used; site conditions should dictate the area 
needed for the species.
    Newly metamorphosed juveniles tend to disperse short distances 
initially from July through September, and then move farther away from 
the breeding habitat during warm rain events (Jennings 2000, p. 1). 
Additionally, and for reasons that are unclear, juveniles tend to 
disperse away from aquatic habitat occupied by adults. Juvenile 
dispersal is essential for recolonizing temporarily extirpated habitat 
and for preventing genetic isolation because juveniles disperse in more 
directions, and for longer distances, than do migrating adults (Wright 
1999, p. 2; Bulger et al. 2003, p. 94). Dispersal habitat for juveniles 
can be any habitat that provides sheltering vegetation and scattered 
wetlands or streams, including forested areas, nonnative grasslands, 
croplands, and pastures. It is unlikely that juveniles disperse through 
urbanized or suburban areas, suburban developments, or areas separated 
from breeding habitat by impassible barriers. Juveniles dispersing 
along riparian corridors may have higher survivorship, as sheltering 
vegetation and suitable aquatic habitat are both more common in such 
corridors (Jennings 2000, p. 1). Finally, juvenile California red-
legged frogs appear to have less strict requirements for aquatic 
habitat than adults, and tend to segregate away from adults in water 
bodies that are shallower or faster moving than those typically used 
for breeding (Hayes and Jennings 1988, p. 147; Bobzien 2000, p. 1; M. 
Jennings 2000, p. 1).

Dispersal Barriers

    Impassible barriers that impact dispersal of the California red-
legged frog include wide or fast-flowing rivers and streams, lakes 
greater than 50 ac (20 ha), and heavily traveled roads (such as 
highways or freeways) without underpasses or culverts (Reh and Seitz 
1990, pp. 247, 248; Fahrig et al. 1995, pp. 179-181). Passable roadways 
that are heavily used by vehicles may also result in a high rate of 
mortality for California red-legged frog adults and juveniles, and 
other amphibians, thereby limiting dispersal capabilities (Glista et 
al. 2008, pp. 81-82).
    The long-term probability of the survival and recovery of the 
California red-legged frog is dependent upon the protection of existing 
breeding habitat and associated uplands (Fellers and Kleeman 2005, pp. 
1, 17-18), the movement of individuals between aquatic habitat patches, 
and the ability to recolonize newly created or vacated habitats. 
Recolonization of vacant habitat patches, which is vital to maintaining 
the California red-legged frog populations and the recovery of this 
species, is dependent upon landscape characteristics, including 
appropriate distances between suitable breeding and non-breeding 
aquatic habitat, and limited fragmentation of interconnecting habitat 
(Vos and Chardon 1998, pp. 44, 53-56). For this rule, we based our 
designation of critical habitat on areas of high-quality habitat that 
we determined provide for persistence of California red-legged frog 
populations and allow for dispersal within, and in most cases between, 
populations. We did not designate areas subject to anthropogenic 
activities (e.g., urban development) or those that were fragmented or 
unlikely to be restorable (poor quality habitat) unless it was 
determined that these areas were unique for the species (for more 
information, see the Criteria Used to Identify Critical Habitat section 
below).

Previous Federal Action

    On July 20, 2007, we announced that we would review the April 13, 
2006, final rule (published at 71 FR 19243) designating critical 
habitat for the California red-legged frog under the Act (16 U.S.C. 
1531 et seq.)(Service 2007a, pp. 1-2), after questions were raised 
about the integrity of scientific information used and whether the 
decision made was consistent with the appropriate legal standards. 
Based on our review of the 2006 final critical habitat designation, we 
determined it was necessary to revise the critical habitat; however, no 
specific dates for completing such revision were established. 
Subsequently, the Center for Biological Diversity filed a complaint in 
the U.S. District Court for the Northern District of California on 
December 12, 2007, challenging our designation of critical habitat for 
the California red-legged frog (Center for Biological Diversity v. 
Kempthorne, et al., Case No. C-07-6404-WHA). The court entered a 
consent decree on April 2, 2008, requiring a proposed revised critical 
habitat rule to be submitted to the Federal Register by August 29, 
2008, and a final revised critical habitat designation to be submitted 
to the Federal Register by August 31, 2009. On September 16, 2008, we 
published in the Federal Register a proposed revised rule to designate 
critical habitat for the California red-legged frog (73 FR 53491).
    We published a document in the Federal Register on April 28, 2009 
(74 FR 19184): (1) Reopening the public comment period on the revised 
proposed rule to designate critical habitat for the California red-
legged frog (73 FR 53491); (2) announcing the availability of a draft 
economic analysis (DEA) of the proposed rule to revise critical 
habitat; (3) proposing boundary changes to Unit MEN-1 to better reflect 
the occupied habitat for the species; and (4) proposing a change to the 
taxonomic nomenclature for the species. The public comment period 
closed on May 28, 2009.
    The comments received on our DEA (IEc 2009a) during the April 28 to 
May 28, 2009, public comment period led us to revise the DEA (IEc 
2009b). To allow public comment on the revised DEA, an extension to the 
publication deadline of the final determination of critical habitat was 
required. On August 31, 2009, a consent decree was signed by the court 
extending the deadline for the final revised designation of critical 
habitat for the California red-legged frog

[[Page 12819]]

to March 1, 2010. On October 8, 2009, we published a document in the 
Federal Register (74 FR 51825) announcing the availability of the 
revised DEA. We reopened the comment period for an additional 30 days 
to allow all interested parties an opportunity to comment 
simultaneously on the proposed revision of critical habitat and the 
associated revised DEA. This rule represents our final revised 
designation of critical habitat in compliance with the court order.

Summary of Comments and Recommendations

    We requested written comments from the public and peer reviewers 
during three comment periods on the proposed rule to revise critical 
habitat for the California red-legged frog. The first comment period 
opened September 16, 2008 (73 FR 53491), and closed November 17, 2008. 
The second comment period opened April 28, 2009 (74 FR 19184), and 
closed May 28, 2009. The third comment period opened October 8, 2009 
(74 FR 51825), and closed November 9, 2009. During these three comment 
periods, we contacted appropriate Federal, State, and local agencies; 
scientific organizations; and other interested parties and invited them 
to comment on the proposed rule to revise critical habitat for the 
California red-legged frog and the associated DEA. We did not receive 
any requests for public hearings during these comment periods. We did, 
however, receive a request to attend a public meeting in San Andreas, 
California held on October 30, 2008. During the public meeting, we 
provided information and answered questions regarding the designation 
and exclusion processes.
    During the three comment periods we received a total of 113 public 
comments directly addressing the proposed revision of critical habitat. 
In addition we received four responses from peer reviewers we solicited 
to comment on the proposed revised designation. During the first 
comment period we received 80 comments directly addressing the proposed 
revision of critical habitat for the California red-legged frog. During 
the second comment period, we received 19 new comments directly 
addressing the proposed revision of critical habitat for the California 
red-legged frog and the DEA; and during the third comment period we 
received an additional 12 comments addressing the proposed revision of 
critical habitat for the California red-legged frog and the DEA.

Peer Review

    In accordance with our policy published in the Federal Register on 
July 1, 1994 (59 FR 34270), we solicited expert opinions from five 
knowledgeable individuals with scientific expertise that included 
familiarity with the California red-legged frog, the geographic region 
in which the species occurs, and conservation biology principles. We 
received responses from four of the peer reviewers.
    We reviewed all comments received from the peer reviewers and the 
public for substantive issues and new information regarding critical 
habitat for the California red-legged frog. These comments are 
addressed below and incorporated into the final rule as appropriate.

Peer Review Comments

    Comment (1): One peer reviewer stated that the Service used a 
reasonable approach in determining the critical habitat boundaries for 
the California red-legged frog by looking at the core recovery areas as 
identified in the 2002 recovery plan. The reviewer also said the 
Service appropriately evaluated the metapopulation dynamics, unoccupied 
areas, dispersal, and connectivity of habitat for the California red-
legged frog. The peer reviewer concurred with our proposal to raise the 
California red-legged frog to full species level. However, the peer 
reviewer went on to say that the current designation represents only a 
relatively small proportion of the historic geographic range of the 
species and that it is unknown if the California red-legged frog can 
survive long-term in such a reduced range.
    Response: In this current revised designation, we acknowledge that 
we did not include all areas where the California red-legged frog 
occurs and that areas outside the designation either: (1) Do not 
contain essential habitat features, or (2) are not essential to the 
conservation of the species. We believe it is important, however, to 
note that critical habitat designation is a different process than 
development of a long-term management plan such as a recovery plan. A 
critical habitat designation is a specific regulatory action that 
defines particular areas as critical habitat in accordance with the 
statutory definition. Our revised methodology incorporates new 
information to best identify areas that meet the definition of critical 
habitat. As a result, the final revised critical habitat designation 
does not include, for example, all areas that the 2002 recovery plan 
identified as necessary for the conservation of the California red-
legged frog. Therefore, we believe this final revised critical habitat 
designation more precisely maps the essential physical and biological 
features that occur within the geographical area occupied by the 
California red-legged frog at the time of listing, and includes those 
areas containing the most suitable habitat for use by the frog.
    Comment (2): One peer reviewer stated that, although the review of 
dispersal capabilities of the frog were well discussed, it should be 
noted that the studies of dispersal capabilities rely on relatively few 
individuals and likely miss the relatively rare long-range distance 
dispersers. The peer reviewer also mentioned that the Service did not 
discuss whether dispersal events actually result in geneflow between 
metapopulations.
    Response: We believe we have reviewed the most recent scientific 
information on frog dispersal capabilities of the California red-legged 
frog and have used this information appropriately in our designation of 
critical habitat. We acknowledge that the California red-legged frog 
may disperse beyond the dispersal distance of 1 mi (1.6 km) identified 
in the designation (Bulger et al. 1999, p. 11; Fellers and Kleeman 
2007, pp. 279-280). However, as stated by the peer reviewer, these long 
distance movements are rare and represent the exception to dispersal 
events for the species. In addition, the designation is not based 
solely on the 1-mi (1.6-km) dispersal distance but is based on habitat 
features and watershed boundaries that we have determined are connected 
to those areas where the California red-legged frog occurs. We have, 
therefore, included areas in this designation beyond the strict 1-mi 
(1.6-km) distance. We are currently unaware of any completed genetic 
studies regarding the genetic exchange between frog populations and at 
what distance this genetic exchange is considered to be limited and not 
important for the species. Our methodology to include the habitat areas 
surrounding known populations, as well as to connect adjacent 
populations together into discernable units, most likely allows for 
such genetic exchange.
    Comment (3): One peer reviewer applauded our decision to reevaluate 
the 2006 designation, but stated that the Service should incorporate 
the 2001 designation into our analysis and remove areas identified in 
the 2001 designation only if the Service has justifiable scientific 
information or if it can be shown that the 2001 designation

[[Page 12820]]

was inaccurate. The same peer reviewer mentioned that the Service 
should review the units within Sonoma County to ensure that they 
include all uplands within 1 mi (1.6 km). The peer reviewer also stated 
that the entire Sonoma Mountain area from Annadel State Park to Sears 
Point/Highway 37 area should be designated as this area has more than 
15 records of the California red-legged frog, most of which are 
breeding sites. The peer reviewer went on to mention that Unit SON-3 
should be connected to Unit MRN-2 in Marin County to provide 
connectivity between units based on habitat availability and recent 
documentation of new California red-legged frog records within the 
area.
    Response: We agree with the peer reviewer that habitat connectivity 
is important to allow for movement between California red-legged frog 
populations and to maintain genetic variation. We are aware of the 
extensive amount of scientific evidence illustrating the importance of 
habitat connectivity, and we considered this information during the 
development of this critical habitat designation. We acknowledge that 
areas potentially providing connectivity between units were included in 
the 2001 critical habitat designation; however, based on our 
reevaluation of the data available at the time of the 2001 designation, 
data obtained since, and our revised methodology for delineating 
critical habitat, we find that those areas do not meet the definition 
of critical habitat because the available data do not identify specific 
areas between these units that contain the physical or biological 
features essential to the conservation of the California red-legged 
frog. The 2001 designation was based on large-scale watershed 
boundaries and not the local watershed boundaries in this designation. 
We believe the use of the local watershed boundaries is more 
appropriate based on dispersal capabilities of the species and the 
information known on occupancy. The area surrounding the Sonoma and 
Marin County units includes developed areas, dairies, and ranchland. We 
evaluated the areas within the 1-mi (1.6-km) distance from the Sonoma 
and Marin County occurrence records and potential breeding habitats and 
determined that for the most part these areas, although likely used by 
the frog, do not meet our criteria established for this designation. We 
focused our designation to encompass areas that support viable (self-
sustaining or increasing) populations, areas that represent portions of 
the geographic extent of the species within the core areas identified 
in the 2002 recovery plan, and any other unique habitats. We did not 
include all the areas occupied by the California red-legged frog. For 
more information on our criteria for designating critical habitat for 
the California red-legged frog see the Criteria Used To Identify 
Critical Habitat section below.
    Comment (4): One peer reviewer commented on Unit MEN-1 (as 
identified in the September 2008 proposed revised designation), saying 
that it includes northern red-legged frogs (Rana aurora) or hybrids 
between the northern red-legged frog and the California red-legged 
frog. The peer reviewer stated that hybrids between the two species 
occur as far south as Manchester State Beach, but that the exact zone 
of hybridization and its importance to either species is unknown.
    Response: As stated in our April 28, 2009, Federal Register 
publication announcing the availability of the draft economic analysis 
(74 FR 19184), we revised Unit MEN-1 to better reflect new species 
occurrence data within the area and the habitat surrounding those 
records. On further review of the unit, we further adjusted the 
boundaries to include only known California red-legged frog records and 
not hybrid northern red-legged frog records. The unit currently 
includes the habitat from Manchester State Beach south to Riverside 
Road. Unit MEN-1 represents the northern extent of the California red-
legged frog within the North Coast of California and likely represents 
a unique genetic component of the species.
    Comment (5): One peer reviewer concluded that it is unclear whether 
the Service considered climate change in the current designation and 
what effects climate change may have on the California red-legged 
frog's habitat in the future.
    Response: We acknowledge that climate change may alter the 
suitability of the California red-legged frog's habitat in the future. 
However, we are required to designate critical habitat based upon the 
best available scientific data at the time that we finalize the 
designation. For species like the California red-legged frog, we 
conclude relatively higher elevation and moister habitat is likely to 
become increasingly important in the face of climate changes. The 
designated critical habitat units include areas distributed across the 
species range from southern California to Butte and Mendocino County in 
northern California and vary from coastal sea-level locations to 
interior Coast Range areas and higher elevation locations in the Sierra 
Nevada Mountains. The variability of environmental conditions at 
locations across the range of the species would likely become more 
important to the extent that California red-legged frog distribution 
and habitat may shift upward in elevation and northward in distribution 
as temperatures increase and precipitation becomes more variable due to 
climate change. However, at this point in time, reliable projections of 
future climatic conditions and how those conditions may affect the 
California red-legged frog's distribution and habitat in California are 
not available. Consequently, we find it appropriate to designate 
critical habitat for the California red-legged frog in areas occupied 
by the species that currently contain the physical and biological 
features or the areas essential to the conservation of the California 
red-legged. Revisions to the critical habitat designation may be 
necessary in the future to accommodate shifts in the occupied range of 
the California red-legged frog.

Comments from Department of Defense

    Comment (6): The Department of The Army, the National Guard Bureau, 
and the California Army National Guard commented that we should exclude 
Camp San Luis Obispo (CSLO) from critical habitat designation for the 
California red-legged frog under section 4(b)(2) of the Act, for 
reasons including national security and economic impacts.
    Response: The Secretary has determined to exercise his discretion 
under section 4(b)(2) of the Act to exclude lands at CSLO from this 
final designation due to potential impacts on national security (see 
Application of Section 4(b)(2) - Impacts to National Security section).
    Comment (7): The Department of the Air Force commented that we 
should exclude Vandenberg Air Force Base (VAFB) from critical habitat 
designation for the California red-legged frog under section 4(b)(2) of 
the Act, for reasons including impacts on national security, and under 
section 4(a)(3)(B)(i) of the Act, for operating under a draft 
Integrated Natural Resources Management Plan (INRMP).
    Response: The Secretary has determined to exercise his discretion 
under section 4(b)(2) of the Act to exclude lands at VAFB from this 
final designation due to potential impacts on national security (see 
Application of Section 4(b)(2) - Impacts to National Security section).

Public Comments

Comments Related to Site-Specific Areas or Issues

    Comment (8): Four commenters opposed designation of parts or all of 
proposed Unit CAL-1 because they believe that the majority of the area 
constitutes poor habitat for the California red-legged frog. Six 
commenters stated that most of the area is too dry for the California 
red-legged frog to occur, and that most ponds and streams are dry for 4 
to 5 months of the year. Two commenters noted that perennial ponds and 
streams support populations of predatory fish and bullfrogs and would 
not support California red-legged frogs.
    Response: We consider Unit CAL-1 to contain high-quality habitat 
because it contains the physical and biological features essential to 
the conservation of the species and has not been subject to 
fragmentation due to development. The habitat within the unit includes 
areas of aquatic breeding habitat that hold water for a minimum of 20 
weeks in all but the driest years, areas of non-breeding aquatic 
habitat, and areas of upland and dispersal habitat within 1 mi (1.6 km) 
of aquatic habitat. The California red-legged frog is adapted to dry 
environments. The drying of watercourses and ponds is beneficial in 
that it precludes the use of these habitats by bullfrogs and predatory 
fish. While water bodies free of bullfrogs and predatory fish would be 
optimal, the California red-legged frog can persist in the presence of 
both of these predators under specific conditions such as occur within 
Unit CAL-1. In aquatic systems subject to seasonal drying, it may be 
difficult for bullfrogs to become established. As discussed in the 
background section of the proposed revised critical habitat rule, 
Doubledee et al. (2003, pp. 424-438) studied the relationship between 
bullfrogs and California red-legged frog persistence. That study showed 
that bullfrogs and California red-legged frogs can coexist and persist 
under certain natural and managed regimes. Additionally, periodic 
drying may prevent nonnative warm water fish from becoming established 
as well. Alvarez et al. (2003, pp. 9-12) presented evidence that 
nonnative predatory fish can have a significant effect on juvenile 
California red-legged frog survival in ponds where they co-occur. Of 90 
ponds surveyed in the Los Vaqueros watershed in Contra Costa County, 7 
were found to have nonnative fish. Over 3 years, one or more ponds with 
nonnative fish were repeatedly drained, and all fish were exhaustively 
removed. Compared to surveys conducted before fish removal, surveys 
conducted after fish removal and pond recharge showed juvenile and 
adult California red-legged frog abundance increased dramatically. This 
suggests a strong link between nonnative fish presence and decreased 
California red-legged frog survival. The California red-legged frog is 
adapted to the drying of its aquatic habitat. Moreover, this drying 
assists the frog by eliminating potential predators and competition for 
resources.
    Comment (9): Nine commenters stated that the data on the California 
red-legged frog population in Unit CAL-1 are not sufficient to justify 
critical habitat designation throughout the unit. Five of these claimed 
there is no information to indicate the population still exists, while 
others noted they had never seen such frogs within the unit despite 
long residence and experience with catching bullfrogs in the area. One 
commenter questioned the validity of California red-legged frog 
occurrence as being natural and suggested that the California red-
legged frog was potentially introduced to the area. One commenter asked 
why the unit extends 2.2 mi (3.5 km) from the frog population despite 
our PCEs, which restrict the extent of upland and dispersal habitat. 
Another commenter specifically noted the importance of the California 
red-legged frog population at Unit CAL-1 on the grounds that it is one 
of only six remaining in the Sierra foothills.
    Response: We consider this population to be important to the 
conservation of the California red-legged frog because it is one of six 
remaining populations in the Sierra Nevada foothills, which is a 
historical portion of the species' range (Service 2002, p. 5). Such 
peripheral populations may also have unusual genetic characteristics 
that could prove useful in maintaining the genetic variability of the 
species (Gilpin and Soule 1986, p. 32). Species that are able to 
maintain their genetic variability can more easily adapt to 
environmental changes and therefore be less prone to extirpation or 
extinction. The California Natural Diversity Database (2009) indicates 
the California red-legged frog population was seen relatively recently, 
and we have no evidence to suggest it is no longer extant. Information 
available to the Service confirms the species' presence as recently as 
October 2008. We consider repeated and comprehensive surveys by trained 
personnel to be necessary to conclude a population has been extirpated. 
Based on the information available on the sighting and circumstances 
surrounding the discovery of California red-legged frogs, we have no 
reason to question the validity of the record as being a natural 
occurrence. Also, regardless of whether the population of California 
red-legged frogs was introduced to the area, it is still considered a 
listed species under the Act and still receives the protections of a 
listed entity.
    The size of Unit CAL-1 reflects our methodology and criteria for 
mapping the critical habitat units. We based the proposed boundaries of 
the unit on the local watershed boundaries where California red-legged 
frogs have been sighted. However, in response to public comments and 
site visits by Service staff, we revised the boundaries of the unit to 
better reflect the available habitat within the area and the locations 
used by the California red-legged frog. As a result, we revised the 
extent of the unit and removed those areas that we determined do not 
contain the physical and biological features essential for conservation 
of the California red-legged frog.
    Comment (10): Two commenters noted that Unit CAL-1 is outside the 
core recovery area identified by the recovery plan (Service 2002, p. 
132). One additional commenter asked if surveys had established local 
salinity or temperature levels, or if a habitat suitability index had 
been established for the area.
    Response: We recognize this designation is different than what is 
outlined as essential habitat in the 2002 recovery plan (which largely 
adopted the boundary delineated in the 2001 critical habitat 
designation (66 FR 14625; March 13, 2001)). While we believe the 2001 
designation and the 2002 recovery plan are important for determining 
the extent of habitat use by the California red-legged frog, we have 
significantly more data available today than when we finalized 2001 
critical habitat designation and the 2002 Recovery Plan. We have 
utilized the currently available data to more precisely identify areas 
meeting the definition of critical habitat, in particular, areas 
related to connectivity. We include such areas in this designation 
where the data support the determination that such areas contain the 
physical and biological features essential to the conservation of the 
species. We believe it is important to note that critical habitat 
designation is a different process than development of a recovery plan. 
A critical habitat designation is a specific regulatory action that 
defines specific areas as critical habitat in accordance with the 
statutory definition. A recovery plan is a guidance document, developed 
in cooperation with partners, that provides a roadmap with detailed 
site-specific

[[Page 12822]]

management actions to help conserve listed species and their 
ecosystems. The term ``essential,'' as used in the recovery plan, is 
not necessarily used in the same manner as it is used in the definition 
of critical habitat (section 3(5) of the Act). The recovery plan 
provides important information about the species and the actions that 
are needed to bring about its recovery, while critical habitat 
identifies specific areas that are essential for the species' 
conservation. In addition, although Unit CAL-1 is outside the core 
recovery area established for Calaveras County by the recovery plan, 
that plan was completed in 2002, and could not account for the 
discovery of the California red-legged frog population in 2003.
    We have not conducted water quality surveys or developed habitat 
suitability index models for proposed critical habitat units. The 
extent of the designation would make these efforts impractical. We have 
determined that specific water salinity or other water monitoring 
aspects are not necessary because the California red-legged frog is 
recently confirmed to be occupying the area and the landowner maintains 
suitable habitat as a result of agreements with the Service. Based on 
the best scientific information available to us at this time, we 
believe that the area within Unit CAL-1 that we are designating as 
critical habitat for the California red-legged frog is appropriate and 
necessary.
    Comment (11): Five commenters indicated we could do more for 
California red-legged frog conservation by pursuing conservation 
agreements with landowners in the vicinity of Unit CAL-1, rather than 
by designating the unit. Thirty-five signatories of a form letter 
indicated they would be less likely to participate in conservation 
partnership projects with us in the future if we designate this unit.
    Response: Although we are aware that the establishment of 
partnerships with private landowners is essential to the conservation 
of many species including the California red-legged frog, we are not 
able to forego the designation of critical habitat based on the 
possibility of establishing conservation partnerships in the future. We 
must adequately weigh the benefits, pursuant to section 4(b)(2) of the 
Act, for conserving the California red-legged frog and its habitat from 
the partnerships and resulting conservation programs and plans relative 
to the regulatory benefits of designating the specific areas as 
critical habitat. Despite our exclusion of this unit in our 2006 final 
critical habitat designation (71 FR 19243), landowners wishing to build 
partnerships have not approached us despite our efforts to establish 
such willing partnerships with landowners. It was not until after we 
published our proposed revised designation on September 16, 2008 (73 FR 
53491), that landowners within Unit CAL-1 contacted us regarding 
developing potential partnerships. On October 30, 2008, we attended a 
public meeting in San Andreas, California, to provide information on 
the proposed revised designation, and we were subsequently approached 
by several landowners interested in forming partnerships and working 
with the Service on conservation measures for the California red-legged 
frog on their private property. However, due to the short court-ordered 
timeframe of this action, we have not been able to finalize any 
agreements or management plans for the frog or its habitat with these 
landowners. We have, however, been able to meet with these landowners 
during site visits to discuss potential habitat restoration activities 
or other conservation measures for the California red-legged frog on 
their properties. We will continue to work with local landowners and 
seek new partnerships regarding the frog in the future.
    Comment (12): Ten commenters, and an additional 35 signatories of a 
form letter, requested exclusion of Unit CAL-1 under section 4(b)(2) of 
the Act. They stated that the benefits of such exclusion would outweigh 
the benefits of designation for the following reasons:
    (1) Routine grazing practices benefit the California red-legged 
frog, and designation would increase the liabilities on such practices;
    (2) Designation would trigger review of Farm Bill conservation 
grant projects under section 7 of the Act, thereby decreasing the 
incentive to apply for such grants;
    (3) Designation negatively impacts landowners but provides little 
benefit to the species;
    (4) Much of the land in the unit is already protected by incentives 
under the Williamson Act to keep the land in agricultural uses;
    (5) Designation could impact water deliveries to farmers and 
interfere with road repair, the clearing of logjams from streams, and 
other infrastructure maintenance;
    (6) Designation would limit development and the planting of crops; 
and
    (7) Designation would lower property values.
    Response: We finalized a special rule under section 4(d) of the Act 
for the California red-legged frog in 2006 (71 FR 19243; April 13, 
2006) that exempts routine ranching operations from the take 
prohibitions of the Act. We recognize livestock ranching as a dynamic 
process, which requires the ability to adapt to changing environmental 
and economic conditions. However, many of the activities essential to 
successful ranching are considered routine, and are undertaken at 
various times and places throughout the year as need dictates. Although 
the 4(d) special rule is not intended to provide a comprehensive list 
of those ranching activities considered routine, some examples include: 
maintenance of stock ponds; fence construction for grazing management; 
planting, harvest, and rotation of unirrigated forage crops; 
maintenance and construction of corrals, ranch buildings, and roads; 
discing of field sections for fire prevention management; control of 
noxious weeds by prescribed fire or by herbicides; placement of mineral 
supplements; and rodent control. The final version of the 4(d) special 
rule includes an expanded definition of routine ranching practices and 
incorporates additional activities we believe are consistent with the 
conservation of the California red-legged frog. These activities are 
those that may provide conservation benefits to the California red-
legged frog. The ranching activities listed in the 2006 final critical 
habitat designation (71 FR 19243; April 13, 2006) are examples of 
practices that we understand are routine to managing an active ranching 
operation. Our intention is not to limit activities that may be 
necessary to the operation of a ranch. As a result of implementing the 
4(d) special rule, we are unaware of any increased liabilities 
associated with ranching operations having a higher liability than 
those areas not dedicated to ranching.
    The final economic analysis (EA) prepared for this designation 
calculates the impact of critical habitat on agricultural land values 
by measuring its effect on the likelihood and profitability of 
residential and commercial development. One comment stated that farm 
subsidies may trigger a consultation under section 7 of the Act and 
that these costs should be included in the final EA. This linkage is 
speculative, and there is no instance of a farm subsidy being used as 
the basis for a consultation with the Service. Further, activities 
including discing, plowing, irrigation, chemical application, 
harvesting, and others that are part of normal agricultural operations 
are also unlikely to trigger a section 7 consultation. Incremental

[[Page 12823]]

costs to farming operations may result from construction of stream 
crossings, water diversion, and sediment and debris removal; these 
costs are discussed in the final economic analysis. Existing regulatory 
mechanisms such as the California Land Conservation Act of 1965 
(commonly referred to as the Williamson Act) may afford some regulatory 
protection to the California red-legged frog. However, the protection 
afforded by these regulations does not sufficiently protect the species 
to such an extent that it would warrant consideration for exclusion 
under section 4(b)(2) of the Act. The Williamson Act is a voluntary 
contract between participating landowners and cities or counties to 
voluntarily restrict land use to agricultural or open-space uses. The 
term of the contracts is a minimum of 10 years, and the landowner may 
petition to cancel the contract. Also the conditions of the contracts 
vary by city or county or even landowner and would not specifically 
identify conservation measures for the frog. Therefore, as a result of 
implementing the 4(d) special rule, our review of the Williamson Act 
conditions, and review of the economic costs associated with Unit CAL-
1, we have determined that the measures identified by the commenters do 
not warrant further consideration for our exclusion of the unit under 
section 4(b)(2) of the Act.
    Comment (13): Five commenters asked us to exclude agricultural land 
in Marin County under section 4(b)(2) of the Act. They stated that the 
benefits of such exclusion would outweigh the benefits of designation 
for the following reasons:
    (1) Routine grazing practices benefit the frog, and designation 
would increase the liabilities on such practices;
    (2) Designation would trigger review of Farm Bill conservation 
grant projects under section 7 of the Act, thereby decreasing the 
incentive to apply for such grants;
    (3) Designation negatively impacts landowners economically but 
provides little benefit to the species;
    (4) Designation could impact water deliveries to farmers and 
interfere with road repair, the clearing of logjams from streams, and 
other infrastructure maintenance; and
    (5) Designation would lower property values.
    Response: See our response to Comment (12) above.
    Comment (14): One commenter noted that we provided incorrect area 
estimates for Federal and private lands in proposed unit ELD-1. The 
commenter also stated that designation of private lands within the 
proposed unit would be inconsistent with the El Dorado County General 
Plan.
    Response: We have revised the land ownership for Unit ELD-1 to 
correctly reflect the landownership within the unit. When designating 
critical habitat, we base our designation on the essential habitat 
features required by the species. When exercising our discretion to 
exclude areas from critical habitat under section 4(b)(2) of the Act, 
we must weigh the benefits of designating against the benefits of not 
designating critical habitat. Such exclusions are usually based on 
finalized management plans, habitat conservation plans, or other 
documents and not on local general plans unless there is a high degree 
of certainty that conservation measures will take place for a 
particular species and that those measures are more beneficial than the 
designation of critical habitat. We have reviewed El Dorado County's 
general plan and found no measures specific to the conservation of the 
California red-legged frog or its habitat. The County identifies 
numerous goals in the Conservation and Open Space Element within its 
general plan; however, no specific measures with respect to the 
conservation of the primary constituent elements for the California 
red-legged frog are mentioned. While we value El Dorado County's 
voluntary agreement in the interagency protection of Spivey Pond, based 
on the general plan, we have not exercised our discretion to exclude El 
Dorado County in its entirety from designated critical habitat. We 
have, however, exercised our discretion to exclude those areas managed 
by the Bureau of Land Management (BLM) at Spivey Pond in El Dorado 
County based on an interagency land use management plan (see 
Application of Section 4(b)(2) of the Act section below).
    Comment (15): One commenter stated that we should include 
downstream portions of Weber Creek in proposed unit ELD-1, as that area 
contains habitat elements essential to the conservation of the species.
    Response: We used the best scientific information available in 
determining those areas that contain the physical and biological 
features essential for the California red-legged frog and that we 
therefore proposed as critical habitat. During our determination 
process, we considered several criteria in the selection of areas that 
contain the features essential for the conservation of the California 
red-legged frog. We did not include all available habitat or all areas 
where frogs are located within the designation. Although the Weber 
Creek area may contain some primary constituent elements, we believe 
the arrangement and quantity of those features may not be adequate. For 
more information, please see the Criteria Used to Identify Critical 
Habitat section below.
    Comment (16): One commenter asked us to remove a specific property 
from SOL-2 on the basis that some of it is too dry to constitute good 
habitat, while the rest is not within 1 mi (1.6 km) of a known 
occurrence, nor is it uplands connecting several occurrences. The 
commenter also requested exclusion from the critical habitat 
designation on economic grounds, arguing that designation would prevent 
conversion of over 900 ac (364 ha) of land suitable for winegrowing, 
resulting in a cost of $3.5 million in gross revenue. Another commenter 
stated that we appropriately designated land within Units SOL-1, SOL-2, 
and SOL-3 in that designation of this land will assist in conserving 
the California red-legged frog and its habitat. The commenter suggested 
that additional areas adjacent to Unit SOL-1 be part of the designation 
including areas along Highway 680 and adjacent to Suisun Marsh in 
Solano County. The commenter also stated that the Service should ensure 
that ``these critical habitat designations not be overridden by 
presumed `public' benefits'' for other uses such as wind energy or 
electrical transmission lines.
    Response: We based this final revised critical habitat designation 
on California red-legged frog occurrence records, habitat surrounding 
those localities, and local watershed boundaries. The occurrence 
records within Unit SOL-2 are associated with the drainages in the 
Jameson Canyon area. Our determination of the unit boundaries focused 
on incorporating not only the occurrence records but also any adjacent 
habitat up to the local watershed boundary as long as we could 
determine that the habitat within the watershed was reasonably 
connected. In some cases where the records were isolated and habitat 
not extensive, we used the 1-mi (1.6-km) dispersal distance to 
determine the extent of the designation. In other cases where the 
habitat was similar or included adjacent water courses within the 
dispersal distance of the California red-legged frog, we looked at the 
habitat and watershed boundaries to guide our designation (see Criteria 
Used To Identify Critical Habitat section below). In regards to the 
areas adjacent to Unit SOL-1 along Highway 680, we believe we have 
properly designated the specific areas where those physical or 
biological features essential to the conservation of the species are 
found. Extending the unit to these adjacent

[[Page 12824]]

areas would require, as the commenter points out, the species to cross 
under the multilane highway through a culvert. Our review of the use of 
the area by the California red-legged frog shows the species in upland 
grassland habitats with no records into the Suisun Marsh area. Although 
the species may be able to access and use the Suisun Marsh area, we 
believe the species is more likely to use the upland grassland habitats 
and not the brackish marsh habitats associated with the Suisun Marsh. 
As a result of our examining the available habitat within the area and 
use of our mapping criteria, we believe we have used the best 
scientific information available on determining the critical habitat 
boundaries including those for Units SOL-1 and SOL-2.
    The final economic analysis prepared for this designation 
calculates potential impacts to agricultural crop farming activities. 
According to the final economic analysis, the relative incremental 
costs associated with the designation within Unit SOL-2 is less than 1 
percent of the total incremental costs of the designation and only 3 
percent of the total incremental costs associated with agricultural 
crop farming activities. Based on these results, we do not consider the 
estimated costs associated with the designation of critical habitat 
within Unit SOL-2 to be disproportionate and have not exercised our 
discretion to exclude any area within Unit SOL-2 under section 4(b)(2) 
of the Act. See ``Exclusions Under Section 4(b)(2) of the Act - 
Economic Exclusions'' section below for more information regarding 
exclusions.
    Comment (17): The San Francisco Public Utilities Commission 
(Commission) wrote in support of the two units proposed on portions of 
its property. Those units are SNM-1 and ALA-2 in San Mateo and Alameda 
Counties. The commenter added that the Commission has enacted 
additional protections for the frog, and that it is also preparing 
habitat conservation plans (HCPs) with the Service to protect 
endangered and threatened species and enhance their habitats within 
those areas.
    Response: We appreciate the support and look forward to working 
with the commenter in the future on continued conservation efforts for 
the California red-legged frog. We do not expect the HCPs to be 
completed by the time this designation is made effective (see the DATES 
section).
    Comment (18): Three commenters stated that they were not properly 
notified of the proposed rule, despite being landowners in designated 
areas or having submitted comments in the past.
    Response: We published the proposed critical habitat designation in 
the Federal Register on September 16, 2008 (73 FR 53491), and we 
accepted comments from all interested parties for 60 days, ending 
November 17, 2008. We then extended the public comment period for an 
additional 30 days (74 FR 19184; April 28, 2009). We later reopened the 
public comment period again for another 30 days (74 FR 51825; October 
8, 2009). For each publication, the Service wrote press releases that 
resulted in newspaper articles throughout California and specifically 
noticed the proposed designation in pertinent newspapers in the range 
of the California red-legged frog. We held a public meeting where we 
discussed opportunities for the public to comment and provide input and 
information. Thus, although we did not specifically notify individual 
landowners within the designation, we believe we provided adequate 
opportunity for individuals to review and provide comment on the 
proposed revised rule. It is our practice to include on our mailing 
lists those individuals who have made comments in the past regarding a 
specific issue. We apologize for having inadvertently failed to notify 
certain people of the proposed action and have updated our records 
accordingly.
    Comment (19): A commenter requested exclusion of approximately 
3,000 ac (1,214 ha) of private land proposed within unit MNT-3 because 
there is an existing conservation easement that protects habitat in 
this area.
    Response: Our review of the easement indicates that: (1) It 
primarily is intended to protect viewshed resources; (2) it covers only 
a portion of the area requested for exclusion; and (3) it allows a 
variety of uses that could adversely affect the physical and biological 
features essential to the California red-legged frog, including new 
utilities and highway improvements, clearing of vegetation for fire 
management, and changes in water use. We have therefore determined not 
to exercise our discretion to exclude these areas under section 4(b)(2) 
of the Act.
    Comment (20): A commenter requested designation of an additional 
critical habitat unit encompassing the Moss Beach, Sawmill Gulch, Seal 
Rock Creek, Fan Shell, and Carmel Bay watersheds on the Monterey 
Peninsula in Monterey County.
    Response: Our approach to designating critical habitat includes 
designating areas with a high density of California red-legged frog 
occurrences and avoiding developed and fragmented areas. Our review of 
the information provided by the commenter and information available in 
our files indicates that the area requested for designation is highly 
fragmented by recreational and residential development. The California 
red-legged frog has been observed in the area, with a small number of 
frogs observed at two localities. Although the California red-legged 
frogs occur in watersheds of the Monterey Peninsula, the best available 
information indicates these watersheds are occupied at low densities 
within fragmented habitat. We have therefore determined that the 
requested addition is not appropriate. For more information, please see 
the Criteria Used to Identify Critical Habitat section below.
    Comment (21): One commenter supported the expansion of critical 
habitat to include the Little Sur River, North and South forks of La 
Brea Creek, the North fork and Upper North fork of Matillija Creek, 
Santa Paula Creek and its tributaries, and Agua Caliente Creek. The 
commenter indicated that these areas are important to the survival and 
recovery of the California red-legged frog.
    Response: We contacted the commenter because we were unable to 
locate Agua Caliente Creek on a map. The commenter stated that the 
correct name was Agua Blanca Creek. In our proposed designation of 
revised critical habitat for the California red-legged frog, we 
determined that all occupied habitat did not need to be designated as 
revised critical habitat, nor did we believe it necessary to designate 
unoccupied habitat, based on our determination that enough occupied 
areas representing the distribution of the frog across its range had 
already been determined and that these areas would provide for the 
conservation of the species. Because we have no records of the 
California red-legged frog occupying the Little Sur River, North and 
South forks of La Brea Creek, the North Fork and Upper North Fork of 
Matillija Creek, Santa Paula Creek and its tributaries, or Agua Blanca 
Creek, we consider these areas unoccupied and have not included them in 
this final rule. For more information on our criteria for designating 
critical habitat, please see the Criteria Used to Identify Critical 
Habitat section below.
    Comment (22): One commenter supported the expansion of critical 
habitat to include the Cuyama River and its tributaries, Branch Creek 
and Alamo Creek, the tributaries feeding Lake Cachuma, a portion of 
Sespe Creek, Birabent Canyon, a portion of the

[[Page 12825]]

Sisquoc River, the Arroyo Seco River and its tributaries, and San 
Carpoforo Creek. The commenter indicated that these areas are important 
to the survival and recovery of the California red-legged frog.
    Response: Our designation of revised critical habitat for the 
California red-legged frog does not include all occupied areas. As 
described in the proposed rule, when determining which occupied areas 
are essential to the conservation of the species and meet the 
definition of critical habitat, we considered theories of 
metapopulation persistence, on-the-ground survey data, and California 
red-legged frog longevity. We focused on areas of high California red-
legged frog abundance, areas needed to maintain connectivity between 
aquatic breeding habitat, and areas of unique ecological significance. 
We selected areas that are inhabited by source populations that are 
capable of maintaining their current population levels and capable of 
providing individuals to recruit into subpopulations found in adjacent 
areas. We are aware that California red-legged frogs do occur in the 
areas listed by the commenter; however, these areas are isolated, 
occupied at low densities, or otherwise not essential to the 
conservation of the species; therefore, we have not included them in 
this final designation. For more information on our criteria for 
designating critical habitat, please see the Criteria Used to Identify 
Critical Habitat section below.
    Comment (23): One commenter identified the California red-legged 
frog as a coastal species and stated that the species was never in any 
inland counties until the early 1900s. The commenter concluded that the 
designation of critical habitat for the species outside of coastal 
areas is not justified.
    Response: According to accepted scientific and taxonomic 
information on the California red-legged frog, the species' historic 
and current distribution includes inland counties in the Sacramento and 
San Joaquin Valleys as well as Sierra Nevada and Interior Coast Range 
counties from Riverside to Shasta County, California. According to 
early species distribution accounts and collections by species experts 
(Storer 1925; pp. 235-236), the species was present in the interior 
portions of California well before the 1900s. As a result of the early 
species' range descriptions and collections in accredited scientific 
facilities and currently known occurrence records for the species, we 
have determined that the historic and current range of the species does 
include interior California counties. This information justifies the 
designation of critical habitat within these interior areas.
    Comment (24): One commenter requested not to increase the 
mitigation requirements for the California red-legged frog because it 
will harm the livelihood or restrict activities of private citizens.
    Response: According to section 7(a)(2) of the Act, each Federal 
agency shall, in consultation with the Service, insure that any action 
will not result in the destruction or adverse modification of habitat 
of a listed species . Only activities that have a Federal nexus (i.e., 
that involve a Federal permit, license, or funding, or are carried out 
by a Federal agency) and are likely to destroy or adversely modify the 
area of critical habitat will be affected. If this is the case, we will 
work with the Federal agency and, where appropriate, applicants for 
Federal permits or license, or for Federal funding, to modify their 
projects so that those projects will not adversely affect the critical 
habitat. Thus, most Federal projects are likely to go forward, but some 
will be modified to minimize harm to critical habitat. Critical habitat 
does not set mitigation requirements for a species.
    Comment (25): One commenter identified pesticide use and pesticide 
drift from agricultural use, not habitat loss, as the major threat 
impacting the California red-legged frog. The commenter also stated the 
decline in frog populations worldwide is a result of disease and 
climate change and that fish are not at all the cause of the species' 
decline. The commenter stated that the designation of critical habitat 
is a typical ``knee-jerk'' reaction to frog species' decline and does 
not address the problem.
    Response: In our May 23, 1996, final listing determination (61 FR 
25813), we determined that habitat loss and fragmentation from urban 
encroachment (along with other factors) constituted the dominant factor 
leading to the listing of the species. Since the listing, numerous 
studies have looked at pesticide drift as the potential cause of 
amphibian declines in California. According to several studies, the 
transport and deposition of pesticides from the agriculturally 
intensive Central Valley of California to the adjacent Sierra Nevada is 
well documented, and pesticides have been found in the bodies of Sierra 
frogs (Davidson et al. 2002, pp. 1589-1590; Davidson 2004, pp. 1892-
1902). However, to date, no direct links have been found between 
pesticides and actual amphibian population declines. We are currently 
consulting with the Environmental Protection Agency (EPA) on the use of 
66 pesticides on or near areas where the California red-legged frog 
occurs to determine appropriate conservation measures for the species. 
We disagree with the commenter that fish are not an issue in the 
species' decline because the introductions of nonnative warm water fish 
(e.g., bass, sunfish, and mosquito fish) have caused some declines in 
the species' distribution and abundance throughout its range (Service 
1996, p. 25827). We agree with the commenter that other factors in 
addition to habitat loss are contributing to a world-wide decline in 
frog and other amphibian populations and that, in some species, disease 
is the major factor. However, in the case of the California red-legged 
frog, we continue to assert that habitat loss and fragmentation 
continue to be the dominant factors in preventing the recovery of the 
species. In response to the commenter's statement that the designation 
is only a reaction to current amphibian declines, we have designated 
critical habitat according to our implementing regulations at 50 CFR 
424.12, by using the best scientific data available and defining 
specific areas that contain those essential physical or biological 
features essential to the conservation of the species and which may 
require special management considerations or protection. Consistent 
with these regulations, we have determined the areas designated as 
critical habitat are appropriate for conservation of the California 
red-legged frog.
    Comment (26): One commenter: (1) Stated that the designation as 
proposed is essential for the proper protection of this species, and 
(2) emphasized the importance of maintaining buffer zones around 
wetland areas, and (3) agreed that the methodologies employed in the 
designation were a practical means for determining the extent of the 
critical habitat boundaries. The commenter stated that that 
methodologies used would assist in protecting both the aquatic features 
and habitat corridors between wetland features and thus allow the 
necessary genetic exchange between populations.
    Response: In accordance with 50 CFR 424.12, we designated critical 
habitat on the basis of the best scientific data available, after 
taking into consideration the probable economic and other impacts of 
making such a designation. In designating critical habitat, we 
considered those physical and biological features that are essential to 
the conservation of the California red-legged frog and that may require 
special management considerations or

[[Page 12826]]

protection. We are not designating buffer zones around those features 
we determined to be essential. An area we designate as critical habitat 
is not a refuge or sanctuary for the species; it serves as a reminder 
to Federal agencies that they must make special efforts to protect the 
important characteristics of the areas designated. Listed species and 
their habitats are protected by the Act whether or not they are in an 
area designated as critical habitat.
    Comment (27): One commenter stated that we should exclude all areas 
being considered as part of the proposed Santa Clara Valley Habitat 
Conservation Plan (SCVHCP) under section 4(b)(2) of the Act, because 
the California red-legged frog is a covered species, an administrative 
draft has been developed and released to the public, and the exclusion 
would follow past Service practice in previous exclusions such as with 
the East Contra Costa HCP.
    Response: When considering the exclusion of areas that are covered 
by conservation plans from critical habitat under section 4(b)(2) of 
the Act, we must determine whether the benefits of such exclusion 
outweigh the benefits of specifying such areas as critical habitat. 
Such exclusions are usually based on finalized management plans, HCPs, 
or other documents that provide a high degree of assurance that 
conservation measures will be implemented and effective for a 
particular species and its habitat, and that those measures are more 
beneficial than the designation of critical habitat. The current 
information on the SCVHCP made available to stakeholders and resource 
agencies consists of early administrative drafts and only portions of 
the entire document. The information is not intended for public review 
and comment and is not final documents. Because they are incomplete, 
the documents have not gone through section 7 intra-Service 
consultation regarding effects to endangered species. The Service's 
current position is not to consider areas for exclusion that are 
covered by draft conservation programs or plans. Draft documents and 
their proposed conservation measures are subject to change. Without a 
high degree of assurance that conservation measures will be implemented 
and effective for a particular species and its habitat, we cannot 
complete a meaningful analysis under section 4(b)(2) of the Act.
    Comment (28): One commenter objected to the redefinition of 
``occupied at the time of listing'' and said the redefinition was 
arbitrary and capricious because the Service did not articulate its 
rational for the change.
    Response: In the previous final critical habitat designation, we 
interpreted the ``occupied at time of listing'' standard to include 
only those specific records mentioned in the final listing rule (61 FR 
25813, May 23, 1996). The purpose of the listing rule is to identify 
threats to a species and determine whether or not listing the species 
under the Act is necessary. The final listing rule is not intended as a 
complete listing of all specific locations where a species occurs. The 
records identified in the final listing rule were not the only 
locations where California red-legged frogs existed but only those 
reported to scientific, higher education, or informational sources. 
Other occupied areas outside those specifically mentioned in the final 
listing rule existed for the frog. In this designation, we interpreted 
occupancy ``at time of listing'' based on the dates of occurrence 
records and life history of the California red-legged frog. For 
example, if an occurrence was recorded after the 1996 listing, but we 
could determine based on population size, demographics, and biological 
factors that the population was most likely present at time of listing, 
we considered that area to be occupied at the time of listing for this 
designation of revised critical habitat. When determining occupancy, we 
considered theories of metapopulation persistence, on-the-ground survey 
data, and California red-legged frog longevity. Bulger et al. (2003, 
pp. 85, 92) found that more than 75 percent of California red-legged 
frogs are resident at permanent aquatic habitats over the course of a 
year, thereby providing local population stability. Survey data 
provided to us during the development of this and previous critical 
habitat rules show an average persistence of 19 years for the 
California red-legged frog populations. Additionally, the California 
red-legged frog is considered long-lived, with a minimum longevity of 
male and female California red-legged frogs of between 8 and 10 years, 
respectively (Jennings et al. 1992, p. 3), which also contributes to 
generational and metapopulation stability. By limiting our previous 
designation to only those specific records identified in the listing 
rule and using an overly narrow definition of occupancy at the time of 
listing, we were not including many records which were identified 
before 1996, or any records present but not specifically identified in 
the listing rule. The process for designating critical habitat in this 
rule is consistent with the standards required by our implementing 
regulations at 50 CFR 424.12 on using the best scientific data when 
designating critical habitat.
    Comment (29): One commenter stated that the elimination of the 
upward boundary for upland habitat was arbitrary and capricious in that 
it deferred designation of critical habitat to the consultation process 
under section 7 of the Act.
    Response: We did identify the upland distance surrounding aquatic 
features within the current designation. The primary constituent 
element (PCE 3), as identified in the 2006 final critical habitat 
designation, limited the upland areas to 200 ft (60 m) from the water 
feature. Based on new biological information on protecting breeding and 
non-breeding aquatic features for the California red-legged frog and 
movements of the frog between breeding and non-breeding habitat 
(Fellers and Kleeman 2007, pp. 276-286), we have extended the upland 
distance surrounding the breeding and non-breeding aquatic features. In 
general, the upland habitat surrounding the aquatic breeding and non-
breeding habitat (PCEs 1 and 2) would be limited to 1 mile (1.6 km) in 
most cases, depending on surrounding landscape and dispersal barriers.
    Comment (30): One commenter stated that several units or portions 
of units be removed from the designation because they are within 
planned development areas as identified in County or City general plans 
and these areas, according to the preamble of the proposed revised 
critical habitat rule, should not be designated according to the 
methodology used in determining the critical habitat boundaries. An 
additional commenter stated that we should not remove areas of planned 
development because arbitrarily removing these areas is not a valid 
biological reason.
    Response: We are basing this final designation of revised critical 
habitat on the best scientific data available, after taking into 
consideration the probable economic and other impacts of making such a 
designation in accordance with our implementing regulations at 50 CFR 
424.19. As we state in the preamble of our 2008 proposed rule to revise 
critical habitat (73 FR 53500), our methodology and the criteria we 
used to determine the critical habitat boundaries were not intended to 
exclude all planned development as identified in city, county, or 
regional general plans. The methods and criteria we used to map areas 
adjacent to development removed areas only if (1) they do not contain 
sufficient PCEs to support one or more of the species' life processes, 
or (2) they have low-quality PCEs because either

[[Page 12827]]

the area is highly degraded and is likely not restorable or the area is 
small, highly fragmented, or isolated and may provide little or no 
long-term conservation value. As a result, we do not believe it would 
be appropriate to automatically exclude planned development areas from 
the designation.
    Comment (31): One commenter requested exclusion from the 
designation of critical habitat in Unit SLO-4 between the town of Pozo 
and the National Forest boundary south of Pozo. The commenter stated 
that designation of critical habitat on private land can significantly 
depreciate the value of the property, affecting the landowner's ability 
to acquire operating capital. The commenter further stated that 
designation of critical habitat can make habitat-enhancing projects 
(i.e., water troughs and delivery systems) cost-prohibitive if it is 
necessary to obtain permits for the projects, thereby discouraging 
voluntary measures to enhance habitat for California red-legged frogs. 
The commenter also expressed concerns with our assertion that the 
Salinas River, near the town of Pozo, is occupied by California-red 
legged frogs.
    Response: Section 3(5)(A) of the Act defines critical habitat as 
the specific areas within the geographical area occupied by the 
species, at the time it is listed, on which are found those physical or 
biological features (I) essential to the conservation of the species 
and (II) which may require special management considerations or 
protection. Our criteria for determining features essential to the 
conservation of the species has been to target areas known to be 
occupied by the California red-legged frog at the time of listing; 
including those areas discovered to be occupied since the time of 
listing; or known to possess high-quality habitat likely to be occupied 
based on proximity to known occurrences, contiguous habitat, or 
dispersal capabilities of the California red-legged frog. We included 
large blocks of contiguous habitat that: (1) Provide geographic 
distribution across the range of the species; (2) represent the full 
range of habitat and environmental variability the species occupies; 
(3) avoid conflict with existing commercial and residential 
development; (4) focus on public land, where available; and (5) overlap 
with other critical habitat designations, where possible.
    As noted in the unit description for SLO-4 (see Final Critical 
Habitat Designation section), this area was not known to be occupied at 
the time of listing but is currently occupied. Based on life history 
and population dynamics of the species we have determined that the area 
was most likely occupied at the time of listing. The occurrence records 
for California red-legged frogs in SLO-4 were generated from surveys 
conducted according to Service protocol by the U.S. Forest Service in 
1999. We have reviewed these records and consider them to be our best 
available science. SLO-4 contains the following features that are 
essential for the conservation of the species: aquatic habitat for 
breeding and non-breeding activities (PCE 1 and PCE 2) and upland 
habitat for foraging, dispersal activities, and shelter (PCE 3 and PCE 
4). Also, as noted in the unit description, threats that may require 
special management in this unit include predation by nonnative species 
and habitat disturbance. Therefore, based on the criteria above, we 
have designated SLO-4 as revised critical habitat in this rule.
    We recognize that routine ranching activities may be beneficial to 
the California red-legged frog. In 2006, we published a special rule 
under the authority of section 4(d) of the Act containing the actions 
and prohibitions necessary to provide for the conservation of the 
California red-legged frog (50 CFR 17.43(d)). Under the special rule, 
incidental take of the California red-legged frog is not a violation of 
section 9 of the Act, if the incidental take results from routine 
ranching activities located on private or Tribal lands. We believe that 
this special rule will encourage landowners and ranchers operating on 
non-Federal land to continue their livestock-related practices that are 
important not only for livestock operations, but also for maintaining 
or enhancing habitat for the California red-legged frog.
    Comment (32): One commenter opposed the designation of the Hearst 
Corporation's Jack Ranch property in Unit SLO-1. The commenter stated 
that many areas on the portion of the Jack Ranch within SLO-1 are 
extremely arid, would not support a California red-legged frog 
population, and therefore do not meet the definition of critical 
habitat. The commenter also argued that the Jack Ranch property does 
not meet the definition of critical habitat because the property does 
not require special management considerations or protection. The 
commenter stated that the Jack Ranch has been responsibly managed for 
over 40 years in a manner that has protected and benefited the various 
natural habitats on the ranch. Alternatively, the commenter argued that 
we should exclude the Jack Ranch property from critical habitat because 
the benefits of excluding the ranch outweigh the benefits of including 
it. The commenter asserted that as a result of the current ranch 
management practices in place on the Jack Ranch, the various habitats 
and species present on the ranch are generally flourishing and will 
continue to benefit if these practices are allowed to continue. The 
commenter argued that designating the ranch as critical habitat would 
create regulatory uncertainty, impose economic burdens on the 
landowner, and increase vulnerability to legal challenge that could 
threaten the area's long-term viability as a working ranch.
    Response: Section 3(5)(A) of the Act defines critical habitat, in 
part, as the specific areas within the geographic area occupied by the 
species, at the time it is listed in accordance with the provisions of 
section 4 of the Act, on which are found only those physical and 
biological features (I) essential to the conservation of the species 
and (II) which may require special management considerations or 
protection. Our strategy for determining features essential to the 
conservation of the species was to target areas that are known to be 
occupied by the California red-legged frog at the time of listing; that 
we determined to be occupied since the time of listing; or that are 
known to possess high-quality habitat likely to be occupied based on 
proximity to known occurrences, being part of contiguous habitat, and 
the dispersal capabilities of the California red-legged frog. We 
included large blocks of contiguous habitat that:
    (1) Provide geographic distribution across the range of the 
species;
    (2) Represent the full range of habitat and environmental 
variability the species occupies;
    (3) Avoid conflict with existing commercial and residential 
development;
    (4) Focus on public land, where available; and
    (5) Overlap with other critical habitat designations, where 
possible.
    As noted in the unit description for SLO-1 (see ``Final Critical 
Habitat Designation'' section), this area was known to be occupied by 
California red-legged frogs at the time of listing, is currently 
occupied, and contains the following features that are essential for 
the conservation of the species: aquatic habitat for breeding and non-
breeding activities (PCE 1 and PCE 2) and upland habitat for foraging 
and dispersal activities (PCE 3 and PCE 4). Also as noted in the unit 
description, threats that may require special management in this unit 
include: highway construction, which may remove upland or aquatic 
habitat; overgrazing of aquatic and riparian habitats; and dewatering 
of

[[Page 12828]]

aquatic habitats due to water diversions. Therefore, based on the 
criteria above, occupancy at the time of listing, and the requirement 
for special management, we have designated SLO-1 as critical habitat, 
including a portion of the Jack Ranch property within SLO-1.
    We recognize that routine ranching activities may be beneficial to 
the California red-legged frog. In 2006, we published a special rule 
under the authority of section 4(d) of the Act to provide for the 
conservation of the California red-legged frog (50 CFR 17.43(d)). The 
special rule provides that incidental take of the California red-legged 
frog will not be a violation of section 9 of the Act, if the incidental 
take results from routine ranching activities located on private or 
Tribal lands. We believe that this special rule will encourage 
landowners and ranchers operating on non-Federal land to continue their 
livestock-related practices that are important not only for livestock 
operations, but also for maintaining or enhancing habitat for the 
California red-legged frog.
    Comment (33): One commenter was opposed to the designation of lands 
in Unit SLO-2 in San Luis Obispo County that are covered under the 
Hearst Ranch Conservation Easement (Easement) and Hearst Ranch San 
Simeon Conservation Easement Management Plan (Plan). The commenter 
asserted that California red-legged frogs occurring within the 
boundaries of the Easement will be protected through specific measures 
addressed in the Plan, and therefore, these lands either do not fall 
within the definition of critical habitat contained in section 3 of the 
Act or should be excluded under section 4(b)(2) of the Act. In 
addition, the commenter argued that designation of lands covered under 
the Easement would discourage voluntary conservation initiatives on 
private land.
    Response: We recognize the importance of voluntary conservation 
measures, such as the Hearst Ranch Easement and Plan, which provide 
protections for California red-legged frogs and their habitat. The 
Secretary has determined to exercise his discretion under section 
4(b)(2) of the Act to exclude from critical habitat 34,777 ac (14,074 
ha) of Easement lands that occur in Unit SLO-2. See the Exclusions 
under Section 4(b)(2) of the Act section for additional information.
    Comment (34): One commenter commended our abandonment of methods 
used in determining ``co-extensive'' costs in previous critical habitat 
designations including the previous final designation for the 
California red-legged frog (April 13, 2006, 71 FR 19244). The commenter 
also commended the Service for refraining from claiming in the preamble 
that the designation of critical habitat provides little additional 
protection to most listed species and for refraining from statements 
emphasizing primarily the ``limitations'' of any ``benefits of 
designating'' an area as critical habitat and using this as a basis for 
excluding areas from the designation. The commenter strongly urged the 
Service to ``follow through with changes in interpretations and 
procedures'' as found in the Federal Register notice for the proposed 
designation (September 16, 2008, 73 FR 53491).
    The commenter also pointed out several concerns with the DEA and 
the proposed revised designation. The commenter stated that the DEA 
does not appropriately focus on or address market impacts; stated that 
the DEA is not transparent on whether the ancillary benefits of 
designating critical habitat were appropriately analyzed; and that the 
Service did not fairly account for the benefits and costs of 
designating critical habitat.
    Response: We acknowledge that our past practice of including 
language in the preamble to critical habitat designations stating a 
policy position at that time was not the appropriate forum for doing so 
and has not been conducive for facilitating the appropriate dialogue to 
assist in the conservation of listed species. As stated earlier, we are 
revising this and certain other designations because of inappropriate 
influence of past Department of Interior personnel and have taken into 
account the information reported by the General Accounting Office on 
critical habitat and listing designations. Comments related to the 
Economic analysis are addressed below.

Comments Related to the Economic Analysis

    Comment (35): One commenter requested the exclusion based on 
economic costs of an area in SOL-1 where a mining company plans to 
expand its existing aggregate quarry.
    Response: As described in section 10.2 of the final economic 
analysis (FEA), we revised the report to include discussion of the 
potential economic impacts to the proposed mining project. The company 
states it is already working closely with Solano County and 
representatives of the Service to develop appropriate mitigation 
measures. The options under consideration are consistent with the types 
of project modifications considered in the FEA. Because these 
discussions are already underway, costs are attributed to the baseline 
scenario. Additional impacts resulting from the designation of critical 
habitat are not anticipated.
    Comment (36): One commenter requested exclusion of a portion of an 
existing aggregate quarry overlapping the southern portion of SOL-3 
because it does not contain the PCEs and out of concern that the 
designation may delay implementation of the ongoing reclamation 
process.
    Response: As described in section 10.2 of the FEA, we revised the 
report to include a discussion of this quarry site. The company has 
already submitted a revised reclamation plan to Napa County, which 
incorporates the results of a biological assessment. In addition, the 
company is currently working with the County and the Service to develop 
mitigation measures that will minimize the impact of the reclamation 
operations on the California red-legged frog. Because the company is 
already working with the Service, costs of efforts to protect the 
California red-legged frog are attributed to the baseline scenario. 
Given that the PCEs are not present at the site, delays due to the 
designation of critical habitat are not anticipated.
    Comment (37): Multiple commenters requested the exclusion of 
specific private properties in SLO-1, SLO-2, SLO-3, and SOL-4, based on 
the assumption that the designation will trigger land use restrictions 
limiting current ranching and farming practices, and in SLO-2, that the 
designation will create barriers to future uses of the land for 
development or agricultural purposes.
    Response: The commenters do not provide information about the types 
of farming and ranching activities taking place on these properties. As 
described in Chapters 6 and 7 of the FEA, this analysis relies upon the 
California Department of Conservation's Farmland Mapping and Monitoring 
Program (FMMP) to identify active crop farming and grazing land within 
the study area as of 2006. According to the FMMP, the private 
properties identified by these commenters are classified primarily as 
grazing lands with a small portion of the properties classified as 
agricultural lands. For property identified as agricultural lands, 
these areas are included in the analysis of impacts to agricultural 
activities presented in Chapter 6. For areas identified in these 
private properties as grazing lands, as described in Chapter 7, this 
analysis assumes that ranchers will likely be subject to restrictions 
on the use of 66 named active ingredients. However,

[[Page 12829]]

according to discussions with representatives of the Agricultural 
Commissioner offices in several counties, the impact of the use 
restrictions to date have been relatively minor, as herbicides are only 
used to treat noxious weeds through spot application. To further 
minimize the impact of the restrictions, some Agricultural Commissioner 
offices are also working with affected ranchers to identify alternative 
herbicides not subject to restrictions. Accordingly, while ranchers may 
be affected by California red-legged frog related herbicide use 
restrictions, the nature of the use of herbicides by ranchers is likely 
to vary depending on the specific ranching operation, and the economic 
impacts of any resulting herbicide use restrictions are expected to be 
minor.
    In addition to existing ranching activities, one of the commenters 
notes that approximately 300 ac (121 ha) of the private property 
located in SLO-2 are allocated for development. The commenter does not 
provide specific information about plans for future residential or 
commercial development of the property. As described in Chapter 4 of 
the FEA, this analysis relies on local planning authorities for 
estimates of the number of housing units projected to be built by 2030 
in the study area. In San Luis Obispo County, this analysis relies upon 
data from the San Luis Obispo Council of Governments (SLOCOG). As shown 
in Exhibit 4-4, in SLO-2 this analysis forecasts the development of 241 
ac (98 ha). Baseline impacts associated with consideration of the 
California red-legged frog and its habitat are estimated in this unit 
to be $14.6 million to $58.0 million and incremental impacts are 
estimated to be $3.9 million to $16.4 million, assuming a seven percent 
discount rate.
    Comment (38): Several commenters requested the exclusion of a 
private property in CAL-1 engaged in ranching activities, based on the 
assumption that the designation will trigger (1) land use restrictions 
by local agencies limiting current ranching practices, (2) devaluation 
of the property as a result of barriers to urban development, and (3) 
additional costs should the landowner chose to convert a portion of 
their property to agricultural uses.
    Response: The private property identified by the commenter is 
approximately 1,094 ac (443 ha) in size, of which 247 ac (100 ha) is 
proposed for critical habitat designation in CAL-1. As described in 
Chapter 7, this analysis assumes that ranchers will likely be subject 
to restrictions on the use of 66 named active ingredients. However, 
according to discussions with representatives of the Agricultural 
Commissioner offices in several counties, the impact of these 
restrictions have been relatively minor, as herbicides are only used to 
treat noxious weeds through spot application. To further minimize the 
impact of the restrictions, some Agricultural Commissioner offices are 
also working with affected ranchers to identify alternative herbicides 
not subject to restrictions. Accordingly, while ranchers may be 
affected by California red-legged frog related herbicide use 
restrictions, the nature of the use of herbicides by ranchers is likely 
to vary depending on the specific ranching operation, and the economic 
impacts of any resulting herbicide use restrictions are expected to be 
minor..
    The commenter does not provide specific information about plans for 
future residential or commercial development of the property. As 
described in Chapter 4 of the FEA, this analysis relies on local 
planning authorities for estimates of the number of housing units 
projected to be built by 2030 in the study area. In Calaveras County, 
this analysis relies upon growth projections obtained from Applied 
Geographic Solutions (AGS), which develops forecasts of population and 
households at the census tract level for the entire state of California 
through the year 2018. Growth through 2030 was projected linearly. As 
shown in Exhibit 4-4, in CAL-1 this analysis forecasts the development 
of 300 ac (121 ha). Baseline impacts to development activities in CAL-1 
associated with the consideration of the California red-legged frog and 
its habitat are estimated to be $2.6 million to $7.6 million and 
incremental impacts are estimated to be $2.1 million to $7.0 million, 
assuming a seven percent discount rate.
    There could also be additional property value losses if the 
landowner is not able to develop portions of the property for 
agricultural purposes. In that case, those losses may not be captured 
because this property was not identified as agricultural lands. Without 
additional information on plans for future agricultural development of 
this property, data are not readily available to estimate potential 
future losses.
    Comment (39): One commenter states that the DEA fails to analyze 
the socio-economic and cumulative impacts related to agriculture. The 
commenter anticipates economic impacts stemming from the loss of 
agricultural acreage in production, the loss of jobs, and reductions in 
food and fiber production, and from negative impacts to local 
communities, among other losses.
    Response: As described in Section 6.5 of the FEA, we revised the 
analysis to include the regional economic impacts expected to result 
from the implementation of no-pesticide use areas for 66 pesticide 
ingredients in the study area. The estimated baseline impact of a loss 
16,519 ac (6,685 ha) from agricultural production to the study area in 
an average year is approximately $103.3 million and approximately 2,062 
jobs. The estimated impact of an incremental loss 7,286 ac (2,949 ha) 
from agricultural production to the study area in an average year is 
approximately $23.8 million and approximately 404 jobs. Detailed 
information on direct, indirect, and induced impacts, including job 
losses, is provided in Chapter 6 of the FEA.
    Comment (40): The Small Business Administration (SBA) submitted a 
comment recommending the Service exercise its discretion under section 
4(b)(2) of the Act to exclude the agricultural acres of small business-
owned farmland that the DEA expects to be taken out of agricultural 
production.
    Response: As described in Chapter 6 and Appendix A of the FEA, we 
revised the Initial Regulatory Flexibility Analysis (IRFA) to 
incorporate refined geographic data on active farming lands in the 
study area. Specifically, this analysis relies upon the Farmland 
Mapping & Monitoring Program (FMMP) to identify active crop farming and 
grazing lands, including a newer data set maintained internally by the 
FMMP, that resulted in the reclassification of a significant number of 
cropped acres within the study area as grazing lands. The number of 
cropped agricultural area incrementally affected decreased from 29,413 
ac (11,903 ha) in the first DEA (dated March 3, 2009) to 7,286 ac 
(2,949 ha) in the FEA.
    We also revised the methodology used to estimate the number of 
small farms affected in each county. Small businesses in crop 
production (North American Industry Classification System (NAICS) 
subsectors 1111, 1112, and 1113) are defined by SBA as having annual 
revenues less than $750,000 (hereinafter referred to as ``small 
farms''). Ideally this analysis would rely on geographic data to 
identify the size of farms within the study area and the percentage of 
a farm's total harvested acres potentially removed from agricultural 
production as a result of the pesticide use restriction. However such 
geographic data are not readily available.
    As described in section A.1.3 of the FEA, in the absence of this 
information, this analysis uses publically-available Census data to 
estimate the probability

[[Page 12830]]

that incrementally affected acres are located on small farms and the 
percent of cropland harvested by ``small farms.'' This approach yields 
a lower-bound estimate of the total number of small farms affected in 
the study area of 198. Worst-case annualized incremental impacts are 
anticipated to range between $500 and $168,000 per farm.
    Comment (40): One commenter stated that the Service's failure to 
evaluate the economic benefits of the rule is inconsistent with 
administrative guidance and widely accepted professional standards. 
Further, the commenter stated that the economic benefits of protecting 
critical habitat for the California red-legged frog probably outweigh 
the costs and are too substantial to downplay or ignore. The commenter 
concludes that the Service should devote equal effort to identifying 
and accounting for categories of benefits relative to the rigor devoted 
to identifying costs.
    Response: In the context of a critical habitat designation, the 
primary purpose of the rulemaking (i.e., the direct benefit) is to 
designate areas in need of special management that are essential to the 
conservation of listed species. While a listed species may be the 
primary beneficiary of designated critical habitat, the Act is clear 
that it is the policy of the Federal government to provide a means 
whereby the ecosystems upon which endangered and threatened species 
depend are conserved. By extension, therefore, benefits must somehow 
also accrue to society from a designation or else Congress would not 
have included this provision in the Act. The designation of critical 
habitat may result in two distinct categories of benefits to society: 
(1) use; and (2) non-use benefits. Use benefits are simply the social 
benefits that accrue from the physical use of a resource. Visiting 
critical habitat to see endangered species in their natural habitat 
would be a primary example. Non-use benefits, in contrast, represent 
welfare gains from ``just knowing that a particular listed species' 
natural habitat is being specially managed for the survival and 
recovery of that species.'' Both use and non-use benefits may occur 
unaccompanied by any market transactions.
    A primary reason for conducting the economic analysis is to provide 
information regarding the economic impacts associated with a proposed 
critical habitat designation. Section 4(b)(2) of the Act requires the 
Secretary to designate critical habitat based on the best scientific 
data available after taking into consideration the economic impact, and 
any other relevant impact, of specifying any particular area as 
critical habitat. Economic impacts can be both positive and negative 
and by definition, are observable through market transactions.
    While the Act requires the specific consideration of the economic 
impact of a designation, it does not require the Service to explicitly 
consider any broader social benefits (or costs) that may be associated 
with the designation. In fact, the Service believes that this is by 
Congressional design because the Act explicitly states up front that it 
is the Federal government's policy to conserve all threatened and 
endangered species and the ecosystems upon which they depend. While 
section 4(b)(2) of the Act gives the Secretary discretion to exclude 
certain areas from the final designation, he is authorized to do so 
only if an exclusion does not result in the extinction of the species. 
Thus, the Service believes that explicit consideration of broader 
social values for the species and its habitat, beyond economic impacts, 
is not necessary as Congress has already clarified the importance our 
society places on conserving all threatened and endangered species and 
their natural habitats upon which they depend. In terms of carrying out 
its responsibilities under section 4(b)(2) then, the Service need only 
to consider whether the economic impacts are significant enough to 
merit exclusion of any particular area without causing the species to 
go extinct.
    To support the claim that the benefits of designating critical 
habitat for the frog probably outweigh the costs, the commenter 
provides examples of other situations and environmental regulations 
where studies have shown that the benefits exceed costs. However, this 
evidence does not support a conclusion that the same is true in this 
instance. If environmental regulation always resulted in net benefits, 
there would be no need to conduct economic analyses.
    Finally, no guidance or executive order requires Federal agencies 
to spend equal effort estimating the benefits and costs of regulations. 
Specifically, OMB's Circular A-4 states (p. 26-27), ``some important 
benefits and costs...may be inherently too difficult to quantify or 
monetize given current data and methods''. Chapter 13 of the FEA 
describes qualitatively the types of benefits that may result from the 
designation of critical habitat, including open space benefits, 
improved water quality, aesthetic benefits, flood control, improved 
soil productivity, and regional economic benefits if increased 
visitation results from the former benefits. To quantify these 
benefits, information about the current environmental quality of the 
habitat (e.g., current concentration of pollutants in waterways, 
current capacity of the habitat to absorb flood waters, current 
productivity of the soil) is necessary as a starting point. In 
addition, ecological and hydrologic models are necessary to understand 
how conservation measures such as reduced pesticide use will change the 
concentration of contaminants in the relative waterways. Most of these 
data and models are not readily available, preventing the 
quantification of benefits at this time.
    Comment (41): One commenter states that in its estimate of the 
costs imposed on development activities, the DEA does not consider 
offsetting positive market impacts, particularly in areas outside of 
the designation. Specifically, the commenter states that the Service 
mistakenly reports the gross, rather than net, costs of critical 
habitat designation.
    Response: We considered the potential for shifts in the market that 
would offset the costs experienced by existing landowners and 
developers within the proposed designation and concluded that 
measurable offsetting gains to homeowners, developers, or landowners 
are unlikely. As discussed in detail in Chapter 4 of the FEA, 
anticipated costs to landowners and developers include the 
administrative costs to consult with the Service or to comply with the 
California Environmental Quality Act, the costs of conservation 
measures, and opportunity costs associated with delays in development 
schedules. Anticipated conservation measures include on-site or off-
site habitat restoration and the preservation of off-site habitat 
through the acquisition of mitigation banking credits (see section 
4.7.2 of the FEA).
    If adequate substitutes for areas projected for development are 
available, developers are likely to avoid areas of critical habitat and 
to develope substitute sites instead. Thus, existing owners of land 
parcels that would have been developed absent critical habitat 
experience a devaluation of their property equivalent to the additional 
costs that would have been incurred by the developers to conserve the 
California red-legged frog. As described in section 4.3 of the FEA, of 
the 1,252,096 ac (506,706 ha) of private land within the proposed 
designation, only 5,746 ac (2,325 ha), or less than one percent, of 
this land is anticipated to be developed within the next 22 years. In 
the 20 affected counties, the number of affected acres (hectares) 
ranges from 2 ac (0.8 ha) to 1,034 ac (418 ha), with an average of 287 
ac (116 ha) affected per

[[Page 12831]]

county. Given the relatively small number of affected acres relative to 
the size of the affected counties (hundreds of thousands to millions of 
acres), the availability of suitable substitutes is likely.
    It is possible that the value of land at substitute sites outside 
of critical habitat may increase; however, where many substitutes are 
available, the marginal increase is likely small. Furthermore, 
quantification of such increases requires significant additional data 
describing the geographic characteristics of alternatives and 
construction of complex, general equilibrium economic models of the 
markets for raw land in each county. Finally, no reduction in the 
number of new houses is anticipated. Developers will either move to 
substitute locations or implement the project modifications, which do 
not include conserving habitat on-site. Thus, measurable consumer 
surplus gains in the market for existing houses, and consumer surplus 
losses in the market for new housing, are not anticipated.
    Finally, we note that Quigley and Swoboda (2007, pp. 299-318) 
specifically addressed these issues in the context of critical habitat, 
and found that consideration of additional losses and gains to 
landowners and homeowners outside of critical habitat but within the 
same market is likely to result in higher, rather than lower overall 
cost estimates.
    Comment (42): One commenter stated that they could not identify 
clear evidence that the Service estimated ancillary benefits that are 
measurable in markets through shifts in resource allocation, as 
suggested in Chapter 2 of the DEA. Specifically, the commenter states 
that habitat protection for an aquatic species such as the California 
red-legged frog may enhance water quality or quantity, resulting in 
avoided costs associated with treatment facilities or other water-
supply-related infrastructure. The commenter cites, as an example, a 
study of such benefits resulting from restoring high-quality watersheds 
in Portland, Oregon.
    Response: Assessment of the potential changes in the costs 
associated with treatment facilities or other water-supply-related 
infrastructure first requires an understanding of current water 
quality. In addition, complex fate and transport models of contaminants 
and sediments are necessary to calculate the change in water quality 
likely to result from the implementation of conservation activities 
(e.g., pesticide use restrictions, habitat restoration) protecting 
critical habitat. Finally, engineering cost models of alternative 
treatment technologies are necessary to estimate the incremental cost 
savings associates with a change in water quality. Most of these data 
and models are not readily available; thus, the potential offsetting 
benefit of reduced water treatment costs cannot be quantified or 
monetized at this time.

Summary of Changes from the 2006 Critical Habitat Designation to the 
2008 Proposed Rule to Revise Critical Habitat

    In the proposed revised and final revised designation of critical 
habitat for the California red-legged frog, we determined that it would 
be appropriate to complete our analysis of critical habitat without 
using the 2006 final critical habitat designation as a base from which 
to make changes due to the involvement of Department of the Interior 
personnel that may have inappropriately influenced the extent and 
locations of critical habitat designated in our previous final 
determination. As a result of this unrestricted analysis, the amount 
and distribution of final critical habitat has increased over the 2006 
final critical habitat designation and better represents those areas 
that contain the features essential to the conservation of the species.
    In the 2006 final critical habitat designation for the California 
red-legged frog (71 FR 19281; April 13, 2006), we excluded all Forest 
Service lands managed under the Sierra Nevada Forest Plan Amendment 
(SNFPA) under section 4(b)(2) of the Act. We based this decision on the 
conservation benefits to the frog outlined in the SNFPA. In the 
proposed revised critical habitat designation issued on September 16, 
2008 (73 FR 53491) we asked for public comment regarding the exclusion 
of these lands from the designation under section 4(b)(2) of the Act 
and whether the SNFPA was an appropriate mechanism for exclusion. 
Although the SNFPA addresses the California red-legged frog in Chapter 
4, and states generally that the ``species parameters are similar to 
those applicable to other areas of California'' (USDA 2004, pp. 234-
239), no details are given as to what specific conservation measures 
would be implemented and how these measures would benefit the 
California red-legged frog. The SNFPA does state that the preferred 
alternative is to limit streambank disturbance to 10 percent of any 
reach within critical aquatic refuges and the SNFPA does limit 
streambank disturbance to 20 percent of any reach in general. Again 
these measures are not specific to identify how and where these 
measures will be implemented and how they will benefit the California 
red-legged frog. Consequently, we are not exercising our discretion to 
exclude Forest Service lands from the final designation because the 
SNFPA not including specific measures to protect and conserve the 
California red-legged frog and its habitat.
    In the 2006 final critical habitat designation, we also excluded 
the entire critical habitat unit CAL-1 from Calaveras County, 
California, under section 4(b)(2) of the Act. We based this decision on 
the actions of a single private landowner who has been managing for the 
frog on their property and who has been encouraging additional 
landowners to join efforts to conserve the frog. Since our publication 
of the proposed revised designation of critical habitat in September 
2008 (73 FR 53491), we held a public meeting to discuss the revised 
proposal in San Andreas, California on October 30, 2008, and to answer 
questions regarding the Unit CAL-1. Shortly after the meeting we were 
approached by several private landowners within the unit that are 
willing to work with us on potentially developing conservation efforts 
for the frog on their lands. We are also working with the County of 
Calaveras on developing a Habitat Conservation Plan for the California 
red-legged frog and other listed or sensitive species in the county. 
However, we have not been able to finalize a HCP or other management 
plans to assure development and implementation of conservation measures 
and protection for the California red-legged frog or its habitat. As a 
result we are not excluding the lands within Unit CAL-1 from the 
designation under section 4(b)(2) of the Act.
    In the 2008 proposed revised designation, we used the recovery plan 
for the California red-legged frog (Service 2002, pp. 1-173) as part of 
our criteria. Specifically, we used the 34 core areas described in the 
recovery plan to focus our efforts on where to designate critical 
habitat. We attempted to include areas in this critical habitat 
designation from those 34 core areas that contain those physical and 
biological features essential to the conservation of the species, that 
were unique habitat types for the species, that were a representation 
of the species' geographic range within each core area, and that were 
most appropriate for conservation of the species across its current 
range. When determining critical habitat, we included areas that met 
the definition of critical habitat and that maximized the potential for 
the conservation of the species, and we attempted to avoid potential 
conflict

[[Page 12832]]

with development. As a result, we included several new areas within the 
species' current range as final revised critical habitat. We did not 
designate areas adjacent to development (i.e., planned development 
areas) if we determined that the areas do not contain sufficient PCEs 
to support one or more of the species' life processes, or that the 
areas have low-quality PCEs because either the area is highly degraded 
and is likely not restorable or the area is small, highly fragmented, 
or isolated and may provide little or no long-term conservation value. 
As a result, designations adjacent to highly developed areas are 
``pulled-back'' to areas that are more biologically defensible and less 
likely to be affected by anthropogenic activities. We did not exercise 
our discretion to exclude areas from the designation based solely on 
planned development.
    In the proposed revised critical habitat we also included a new 
unit in the Sierra Nevada (Unit PLA-1); bringing the total number of 
units in the designation to six for the Sierra Nevada region.
    In the 2006 final critical habitat designation, we interpreted the 
``occupied at time of listing'' standard to include only those specific 
records mentioned in the final listing rule (May 23, 1996; 61 FR 
25813). The records identified in the final listing rule were not the 
only locations where California red-legged frogs existed; rather, the 
final listing rule identified only those records reported to 
scientific, higher education, or informational sources. Other occupied 
areas outside those specifically mentioned in the final listing rule 
existed for the California red-legged frog. In this final revised 
designation, we interpreted ``occupied at time of listing'' based on 
the dates of occurrence records and life history of the California red-
legged frog. For example, if an occurrence was recorded after the 1996 
listing, but we could determine based on population size, demographics, 
and biological factors that the population was most likely present at 
the time of listing just not specifically recorded, we would consider 
the area as occupied at the time of listing for this final revised 
critical habitat designation. When determining occupancy, we considered 
metapopulation dynamics, population persistence, on-the-ground survey 
data, and California red-legged frog longevity. Bulger et al. (2003, 
pp. 85, 92) found more than 75 percent of California red-legged frogs 
are resident at permanent aquatic habitats over the course of a year, 
thereby providing local population stability. Survey data provided to 
us during the development of this and previous critical habitat rules 
show an average persistence of 19 years for California red-legged frog 
populations. Additionally, the California red-legged frog is considered 
long-lived, with a minimum longevity of male and female California red-
legged frogs of between 8 and 10 years, respectively (Jennings et al. 
1992, p. 3), which also contributes to generational and metapopulation 
stability.
    In the 2006 rule, we only focused on designating those areas that 
contain large numbers and concentrations of occurrence records. In this 
final revised critical habitat designation we focused on occurrence 
records as well as on areas adjacent to the occurrences that we 
determined are essential or contain the features essential to the 
conservation of the species.
    We revised the primary constituent element that described the 
upland habitat surrounding water features (PCE 3). The PCE in the 2006 
rule limits the upland areas to 200 ft (60 m) from a water feature. 
Based on new biological information on protecting breeding and non-
breeding aquatic features for the California red-legged frog and 
movements of the California red-legged frog between breeding and non-
breeding habitat (Fellers and Kleeman 2007, pp. 276-286), we decided 
that such determinations should be made on a case-by-case basis and 
removed the specific distance surrounding each individual water 
feature. In general, the upland habitat surrounding the aquatic 
breeding and non-breeding habitat (PCEs 1 and 2) would be limited to 1 
mi (1.6 km) in most cases, depending on surrounding landscape and 
dispersal barriers. The 1 mi (1.6 km) distance is also the distance 
used in the Service's site assessment and survey guidelines used in 
analyses under section 7 and section 10 of the Act for consultation 
purposes and allows for a better evaluation of habitat use and 
characteristics of a given area by the frog (Service 2005, pp. 1-26).
    In the 2008 proposed revised critical habitat designation we 
included a new area in Mendocino County (Unit MEN-1) based on new 
genetic information on the northern coastal range of the species 
(Shaffer et al. 2004, pp. 2667-2677). The intent of the new unit was to 
capture habitat that would represent the northern extent of the species 
along the northern California coast. The occurrence information was 
based on CNDDB records (CNDDB 2008).

Summary of Changes from the 2008 Proposed Rule

    On September 16, 2008, we proposed revised critical habitat for the 
California red-legged frog comprising a total of 1,804,865 ac (730,402 
ha) (73 FR 53491). This final revised critical habitat designation 
includes approximately 1,681,938 ac (680,656 ha) in 27 California 
counties in 48 units, after refining areas based on public comment and 
excluding approximately 121,927 ac (49,746 ha) under section 4(b)(2) of 
the Act (see Application of Section 4(b)(2) of the Act section below 
for a detailed discussion).
    In the 2008 proposed revised critical habitat designation, we 
included an area in Mendocino County (Unit MEN-1) as a result of 
genetic information on the northern coastal range of the species 
(Shaffer et al. 2004, pp. 2667-2677). We revised the boundary of this 
unit in the Federal Register document announcing the availability of 
the draft economic analysis on the proposed revised designation of 
critical habitat (74 FR 19184; April 28, 2009). The revised Unit MEN-1 
included approximately 26,875 ac (10,876 ha), a change of an additional 
2,970 ac (1,202 ha) of critical habitat within this unit from the 2008 
proposed revised designation. We revised Unit MEN-1 to better reflect 
new species occurrence data within the area and the habitat surrounding 
those records. On further review of the unit in this final revised 
designation, we have adjusted the boundaries to include only known 
California red-legged frog records or hybrid records genetically 
comprised mostly (50 percent or greater) of the California red-legged 
frog. This percentage was chosen because research on the exact boundary 
between the two species has not yet been determined and we wanted to 
avoid designating critical habitat in areas solely populated by the 
northern red-legged frog (Rana aurora). By choosing such a percentage 
we are ensuring that the designated unit is comprised mostly of pure 
California red-legged frogs. The unit currently includes the habitat 
from Manchester State Beach south to Riverside Road. Unit MEN-1 
represents the northern extent of the California red-legged frog within 
the North Coast of California and likely represents a unique genetic 
component of the species.
    In response to public comments and site visits by Service staff, we 
reevaluated the boundaries of Unit CAL-1 to assess the available 
habitat within the area and the locations used by the California red-
legged frog. As a result, we revised the extent of the unit and removed 
those areas that we determined

[[Page 12833]]

do not contain the physical and biological features essential for 
conservation of the California red-legged frog or that are part of the 
watershed not likely used by the species.
    The Secretary also exercised his discretion to exclude several 
areas from the designation under section 4(b)(2) of the Act due to 
potential impacts on national security (see Application of Section 
4(b)(2) - Impacts to National Security section for further discussion) 
and the Department of Defense's efforts to conserve the California red-
legged frog on their military installations. These areas include: 
Vandenberg Air Force Base (24,913 ac (10,090 ha)) (Units STB-2 and STB-
4) and Camp San Luis Obispo (5,612 ac (2,271 ha)) (Unit SLO-3). The 
Secretary further exercised his discretion to exclude several other 
areas either based on existing management plans or HCPs that 
specifically identify and implement measures to conserve and protect 
the California red-legged frog and its habitat. These areas include: 
Bonnie Doon Quarries Settlement Ponds HCP, Santa Cruz County (6 ac (3 
ha)) (Unit SCZ-1); East Contra Costa HCP/NCCP, Contra Costa County 
(75,767 ac (30,662 ha)) (Unit CCS-2); Western Riverside Multi-species 
HCP, Riverside County (4,069 ac (1,647 ha)) (Unit RIV-1); East Bay 
Regional Park District lands, Contra Costa County (14,627 ac (5,919 
ha)) (Unit CCS-2); Hearst Ranch lands, San Luis Obispo County (34,777 
ac (14,074 ha)) (Unit SLO-2); and Spivey Pond Management Area (BLM), El 
Dorado County (54 ac (22 ha)) (Unit ELD-1). See the section Exclusions 
Under Section 4(b)(2) of the Act for further discussion.

Critical Habitat

    Critical habitat is defined in section 3 of the Act as:
    (1) The specific areas within the geographical area occupied by a 
species, at the time it is listed in accordance with the Act, on which 
are found those physical or biological features
    (a) essential to the conservation of the species and
    (b) that may require special management considerations or 
protection; and
    (2) specific areas outside the geographical area occupied by a 
species at the time it is listed, upon a determination that such areas 
are essential for the conservation of the species.
    Conservation, as defined under section 3 of the Act, means the use 
of all methods and procedures that are necessary to bring any 
endangered or threatened species to the point at which the measures 
provided under the Act are no longer necessary. Such methods and 
procedures include, but are not limited to, all activities associated 
with scientific resources management such as research, census, law 
enforcement, habitat acquisition and maintenance, propagation, live 
trapping, transplantation, and in the extraordinary case where 
population pressures within a given ecosystem cannot otherwise be 
relieved, may include regulated taking.
    Critical habitat receives protection under section 7 of the Act 
through the prohibition against Federal agencies carrying out, funding, 
or authorizing the destruction or adverse modification of critical 
habitat. Section 7(a)(2) of the Act requires consultation on Federal 
actions that may affect critical habitat. The designation of critical 
habitat does not affect land ownership or establish a refuge, 
wilderness, reserve, preserve, or other conservation area. Such 
designation does not allow the government or public to access private 
lands. Such designation does not require implementation of restoration, 
recovery, or enhancement measures by private landowners. Where a 
landowner requests Federal agency funding or authorization for an 
action that may affect a listed species or critical habitat, the 
consultation requirements of section 7(a)(2) of the Act would apply, 
but even in the event of a destruction or adverse modification finding, 
the landowner's obligation is not to restore or recover the species, 
but to implement reasonable and prudent alternatives to avoid 
destruction or adverse modification of critical habitat.
    For inclusion in a critical habitat designation, habitat within the 
geographical area occupied by the species at the time it was listed 
must contain the physical and biological features that are essential to 
the conservation of the species, and be included only if those features 
may require special management considerations or protection. Critical 
habitat designations identify, to the extent known using the best 
scientific data available, habitat areas that provide essential life-
cycle needs of the species (i.e., areas on which are found the primary 
constituent elements laid out in the appropriate quantity and spatial 
arrangement essential to the conservation of the species).
    Under the Act, we can designate an area outside the geographical 
area occupied by the species at the time of listing as critical habitat 
only when we determine that the best available scientific data 
demonstrate that the designation of that area is essential for the 
conservation of the species.
    Section 4 of the Act requires that we designate critical habitat on 
the basis of the best scientific data available. Further, our Policy on 
Information Standards Under the Endangered Species Act (published in 
the Federal Register on July 1, 1994 (59 FR 34271)), the Information 
Quality Act (section 515 of the Treasury and General Government 
Appropriations Act for Fiscal Year 2001 (Pub. L. 106-554; H.R. 5658)), 
and our associated Information Quality Guidelines, provide criteria, 
establish procedures, and provide guidance to ensure that our decisions 
are based on the best scientific data available. They require our 
biologists, to the extent consistent with the Act and with the use of 
the best scientific data available, to use primary and original sources 
of information as the basis for recommendations to designate critical 
habitat.
    When we are determining which areas to designate as revised 
critical habitat, our primary source of information is generally the 
information developed during the listing process for the species. 
Additional information sources may include the recovery plan for the 
species, articles in peer-reviewed journals, conservation plans 
developed by States and counties, scientific status surveys and 
studies, biological assessments, or other unpublished materials and 
expert opinion or personal knowledge.
    Habitat is often dynamic, and species may move from one area to 
another over time. Furthermore, we recognize that designation of 
critical habitat may not include all habitat areas that we may 
eventually determine, based on scientific data not now available to the 
Service, are necessary for the recovery of the species. For these 
reasons, a critical habitat designation does not signal that habitat 
outside the designated area is unimportant or may not be required for 
recovery of the species.
    Areas that support populations, but are outside the critical 
habitat designation, will continue to be subject to conservation 
actions we implement under section 7(a)(1) of the Act. They are also 
subject to the regulatory protections afforded by the section 7(a)(2) 
jeopardy standard, as determined on the basis of the best available 
scientific information at the time of the Federal agency action. 
Federally funded or permitted projects affecting listed species outside 
their designated critical habitat areas may still result in jeopardy 
findings in some cases. Similarly, critical habitat designations made 
on the basis of the best available information at the time of 
designation will not control

[[Page 12834]]

the direction and substance of future recovery plans, habitat 
conservation plans (HCPs), or other species conservation planning 
efforts if information available at the time of these planning efforts 
calls for a different outcome.

Primary Constituent Elements (PCEs)

    In accordance with section 3(5)(A)(i) of the Act and the 
regulations at 50 CFR 424.12, in determining which areas within the 
geographical area occupied by the species at the time of listing to 
designate as critical habitat, we consider the physical and biological 
features essential to the conservation of the species that may require 
special management considerations or protection to be the PCEs laid out 
in the appropriate quantity and spatial arrangement essential to the 
conservation of the species. These include, but are not limited to:
    (1) Space for individual and population growth and for normal 
behavior;
    (2) Food, water, air, light, minerals, or other nutritional or 
physiological requirements;
    (3) Cover or shelter;
    (4) Sites for breeding, reproduction, or rearing (or development) 
of offspring; and
    (5) Habitats that are protected from disturbance or are 
representative of the historical, geographical, and ecological 
distributions of a species.
    We derive the specific PCEs required for the California red-legged 
frog from its biological needs as described below; in the Background 
section of this final rule; in the proposed revised critical habitat 
designation (73 FR 53491; September 16, 2008); and in the final listing 
rule (61 FR 25813; May 23, 1996).

Aquatic Breeding Habitat

    Aquatic breeding habitat is essential for providing space, food, 
and cover necessary to sustain all aquatic life stages of the 
California red-legged frog. It consists of low-gradient fresh water 
bodies, including natural and manmade (e.g., stock) ponds, backwaters 
within streams and creeks, marshes, lagoons, and dune ponds. It does 
not include deep lacustrine water habitat (e.g., deep lakes and 
reservoirs 50 ac (20 ha) or larger in size).
    To be considered essential breeding habitat, the aquatic feature 
must have the capability to hold water for a minimum of 20 weeks in all 
but the driest of years. This is the approximate amount of time needed 
for egg and tadpole development and metamorphosis so that juveniles can 
become capable of surviving in upland habitats (Storer 1925, pp. 242-
243; Wright and Wright 1949, p. 418; Jennings 1988, p. 63). Drying of 
the aquatic habitat after that time can be beneficial because it helps 
prevent the establishment of predators such as fish in the family 
Centrarchidae (bass), mosquito fish (Gambusia affinis), or bullfrogs 
(Lithobates catesbeianus) (Hayes and Jennings 1988, p. 152; Cook 1997, 
pp. ii, iii, 17-19; Scott 1998, p. 3; Lawler et al. 1999, pp. 613-622; 
Frost et al. 2006, p. 369; Cook and Jennings 2007, p. 438; Crother et 
al. 2008, p. 7). Water quality requirements for eggs and tadpoles 
include low salinity (below 4.5 parts per thousand (ppt) for eggs; up 
to 7.0 ppt for tadpoles) (Jennings and Hayes 1990, pp. 18, 19; Jennings 
1994, p. 1), and temperatures below about 73 degrees Fahrenheit (23 
degrees Celsius) (Cook 1997, p. 16; Nussbaum et al. 1983, p. 160). 
Water bodies free of bullfrogs and nonnative predatory fish are 
optimal, but California red-legged frog populations can persist in the 
presence of one or the other of these predators (Kiesecker and 
Blaustein 1998, pp. 776, 782; Lawler et al. 1999, pp. 613, 619-621; 
Cook and Jennings 2007, p. 438).
    Adult California red-legged frogs can survive in moist upland areas 
after breeding habitat has dried, and can live up to 8 to 10 years to 
make new breeding attempts. Therefore, aquatic breeding habitat need 
not be available every year, but it must be available at least once 
within the frog's lifespan for breeding to occur. In addition, the 
aquatic features must have appropriate hydroperiods (ponded habitat 
during the appropriate aquatic phase of the species) in order to 
maintain a California red-legged frog population during most years. 
Without aquatic breeding habitats, the California red-legged frog would 
not survive, reproduce, develop juveniles, and grow into adult 
California red-legged frogs that can complete their life cycles.

Non-Breeding Aquatic and Riparian Habitat

    Non-breeding aquatic and riparian habitat is essential for 
providing the space, food, and cover necessary to sustain the 
California red-legged frog. Non-breeding aquatic habitat consists of 
shallow (non-lacustrine) freshwater features not suitable as breeding 
habitat, such as streams, small seeps, and ponds that dry too quickly 
to support breeding. Riparian habitat consists of vegetation growing 
nearby, but not typically in, a body of water on which it depends, and 
usually extends from the bank of a pond or stream to the margins of the 
associated floodplain.
    Other non-breeding aquatic features that the California red-legged 
frog is known to use include locations such as moist cracks at the 
bottom of dried ponds, seeps, springs, intermittent streams, and small 
ponds. Cracks in the bottom of dried ponds are used as refugia to 
maintain moisture and avoid heat and solar exposure (Alvarez 2004, p. 
162). Fellers and Kleeman (2007, p. 279) found that most California 
red-legged frogs leave their breeding habitat once breeding is 
completed and disperse to non-breeding aquatic habitat locations such 
as those listed above. Without these non-breeding aquatic features, the 
California red-legged frog would not be able to survive drought periods 
or disperse to other breeding habitat.

Upland Habitat

    Upland habitats associated with riparian and aquatic habitat are 
essential to maintain California red-legged frog populations. This 
habitat type provides food and shelter sites for the California red-
legged frog and assists in maintaining the integrity of aquatic sites 
by protecting them from disturbance and supporting the normal functions 
of the aquatic habitat. Upland habitat associated with occupied wetland 
habitat often contains blackberry (Rubus spp.), poison oak 
(Toxicodendron diversilobum), coyote brush (Baccharis pilularis), oaks 
(Quercus sp.), grasses, and other upland species, and serves as 
foraging habitat and provides shelter from predatory species (Service 
2002, pp. 12-14; Fellers and Kleeman 2007, pp. 276-277).
    Upland habitat that contains the features essential to the 
conservation of the species consists of natural areas near the edge of 
the riparian vegetation or the edge of the watershed boundary, and 
includes the dispersal corridor between breeding and non-breeding 
aquatic habitat. This is based on the dispersal capabilities of the 
species (see the Dispersal Habitat section below), and research 
identifying the use of upland areas by the species (Rathbun et al. 
1993, pp. 15, 16; Bulger et al. 2003, pp. 93, 94; Tatarian 2004, pp. 
24, 25; Fellers and Kleeman 2007, p. 279). Tatarian (2004, p. 22) found 
the California red-legged frog inhabiting upland areas for 50 days at a 
distance of 302 ft (92 m) from aquatic habitat; Bulger et al. (2003, 
pp. 87, 88) found that the species is capable of inhabiting upland 
habitats within 200 ft (60 m) of aquatic habitat for continuous 
durations exceeding 20 days; and Rathbun et al. (1993, pp. 15, 16) 
observed California red-legged frogs inhabiting upland riparian habitat 
for durations up to 77 days. California red-

[[Page 12835]]

legged frogs often disperse from their breeding habitat to forage and 
seek suitable upland habitat if aquatic habitat is not available.
    As stated above in the Background section, the California red-
legged frog is documented to disperse from ponds and streams a distance 
over 2.0 mi (3.2 km) (Bulger et al. 2003, p. 90). However, based on a 
review of the most current literature and information gathered in 
development of the recovery plan and subsequent critical habitat 
designations for the species, we determined that the 2.0-mi (3.2-km) 
distance is near the maximum dispersal distance for the species during 
a single season, and that the 1-mi (1.6-km) distance is more reflective 
of the average dispersal distance for the California red-legged frog 
(Rathbun et al. 1993, pp. 15, 16; Wright 1999, pp. 1, 2; Bulger et al. 
2003, p. 90; Tatarian 2004, table 9; Fellers and Kleeman 2005, pp. 14-
16; Fellers and Kleeman 2007, pp. 276-286). In addition, upland habitat 
features will influence California red-legged frog movements in a 
particular landscape. For example, in an area that contains a riparian 
habitat surrounded by drier chaparral habitat you would expect the frog 
to avoid movements into the drier habitat and to use the riparian area 
as a corridor for movement. Based on the landscape characteristics 
within the species' range and the species' reported dispersal 
capabilities, the upland habitat surrounding the aquatic breeding and 
non-breeding habitat (PCEs 1 and 2) would be limited to 1 mi (1.6 km) 
in most cases depending on surrounding landscape and dispersal 
barriers.
    Upland habitat used by the California red-legged frog includes 
structures that provide shade, moisture, and cooler temperatures. These 
structures may be natural, such as the spaces under boulders or rocks 
and organic debris (e.g., downed trees or logs), or they could be 
manmade, such as construction debris or agricultural features (e.g., 
concrete blocks, drains, watering troughs, spring boxes, abandoned 
sheds, stacks of hay or other vegetation). The California red-legged 
frogs will also use small mammal burrows and moist leaf litter as 
refugia (Jennings and Hayes 1994, p. 64; Fellers and Kleeman 2005, p. 
12).

Dispersal Habitat

    Dispersal habitat provides connectivity among California red-legged 
frog breeding (and associated upland) habitat patches. While the 
California red-legged frog can pass many obstacles, and does not 
require a particular type of habitat for dispersal, the habitat 
connecting breeding locations and other aquatic habitat must be free of 
barriers that prevent California red-legged frogs from dispersing.
    Designated dispersal habitat consists of upland and riparian 
habitat contiguous with breeding and non-breeding aquatic habitat that 
is free of barriers, and connects two or more patches of aquatic 
habitat within 1 mi (1.6 km) of one another. Dispersal barriers include 
heavily traveled roads (Vos and Chardon 1998, pp. 44, 54; Glista et al. 
2008, pp. 81-82) that possess no bridges or culverts, moderate- to 
high-density urban or industrial developments with large expanses of 
asphalt or concrete that do not contain the PCEs or features essential 
to conservation of the species, and large lakes or reservoirs over 50 
ac (20 ha). Agricultural lands such as row crops, orchards, vineyards, 
and pastures do not constitute barriers to California red-legged frog 
dispersal.
    The California red-legged frog is documented to travel as far as 
2.2 mi (3.6 km) from non-breeding to breeding habitats (Bulger et al. 
2003, p. 90). These long-distance movements are likely migrations 
rather than use of corridors for moving between habitats (Scott and 
Rathbun 1998, pp. 2, 3). Additionally, these movements occur with 
apparent disregard to topography, vegetation type, or riparian 
corridors (Bulger et al. 2003, pp. 93, 94; Fellers and Kleeman 2005, 
pp. 15, 16). Based on our review of the best scientific data available, 
we conclude that 2.2 mi (3.6 km) is likely near the upward limit of 
dispersal capability for the California red-legged frog within a single 
season and that a 1-mi (1.6-km) dispersal distance will, in most 
instances, provide for connectivity between breeding aquatic habitats, 
non-breeding aquatic habitats, and areas of non-aquatic (i.e., upland) 
habitat and can be used as a general guide for habitat use (Rathbun et 
al. 1993, pp. 15, 16; Wright 1999, pp. 1, 2; Bulger et al. 2003, p. 90; 
Tatarian 2004, table 9; Fellers and Kleeman 2005, pp. 14-16; Fellers 
and Kleeman 2007, pp. 276-286). However, we also concur with Fellers 
and Kleeman (2007, p. 279) in that the exact extent of habitat use by 
the California red-legged frog is influenced by habitat availability 
and the location of movement corridors.
    Accessible dispersal habitat provides opportunities for the 
California red-legged frog to move freely across the landscape in 
search of adjacent breeding and non-breeding habitats. Accessible 
dispersal habitat is considered essential to the conservation of the 
species and provides for: (1) Movement and establishment of home ranges 
by juvenile recruits; (2) Maintenance of gene flow through the movement 
of juveniles and adults between populations; and (3) recruitment into 
new breeding habitat or recolonization of breeding habitat after local 
extirpations.

Primary Constituent Elements (PCEs) for the California Red-Legged Frog

    Within the geographical area occupied by the California red-legged 
frog at the time of listing, we must identify the physical or 
biological features essential to the conservation of the species that 
may require special management considerations or protection. This final 
revised critical habitat designation encompasses those areas containing 
the PCEs that are necessary to support one or more of the species' life 
history functions and that are laid out in the appropriate quantity and 
spatial arrangement essential to the conservation of the species. As 
stated in the Criteria Used to Identify Critical Habitat section of 
this rule, we believe that we can conserve the California red-legged 
frog within its extant range, and we are therefore not including any 
areas outside the geographical area currently occupied by the species. 
Because not all life-history functions require all the PCEs, not all 
areas designated as critical habitat will contain all the PCEs.
    Based on the above needs and our current knowledge of the life-
history, biology, and ecology of the California red-legged frog, we 
determined the California red-legged frog's PCEs are:
    (1) Aquatic Breeding Habitat. Standing bodies of fresh water (with 
salinities less than 4.5 ppt), including natural and manmade (e.g., 
stock) ponds, slow-moving streams or pools within streams, and other 
ephemeral or permanent water bodies that typically become inundated 
during winter rains and hold water for a minimum of 20 weeks in all but 
the driest of years.
    (2) Aquatic Non-Breeding Habitat. Freshwater pond and stream 
habitats, as described above, that may not hold water long enough for 
the species to complete its aquatic life cycle but which provide for 
shelter, foraging, predator avoidance, and aquatic dispersal of 
juvenile and adult California red-legged frogs. Other wetland habitats 
considered to meet these criteria include, but are not limited to: 
plunge pools within intermittent creeks, seeps, quiet water refugia 
within streams during high water flows, and springs of sufficient flow 
to withstand short-term dry periods.
    (3) Upland Habitat. Upland areas adjacent to or surrounding 
breeding and non-breeding aquatic and riparian

[[Page 12836]]

habitat up to a distance of 1 mi (1.6 km) in most cases (i.e., 
depending on surrounding landscape and dispersal barriers) including 
various vegetational types such as grassland, woodland, forest, 
wetland, or riparian areas that provide shelter, forage, and predator 
avoidance for the California red-legged frog. Upland features are also 
essential in that they are needed to maintain the hydrologic, 
geographic, topographic, ecological, and edaphic features that support 
and surround the aquatic, wetland, or riparian habitat. These upland 
features contribute to: (1) Filling of aquatic, wetland, or riparian 
habitats; (2) maintaining suitable periods of pool inundation for 
larval frogs and their food sources; and (3) providing non-breeding, 
feeding, and sheltering habitat for juvenile and adult frogs (e.g., 
shelter, shade, moisture, cooler temperatures, a prey base, foraging 
opportunities, and areas for predator avoidance). Upland habitat should 
include structural features such as boulders, rocks and organic debris 
(e.g., downed trees, logs), small mammal burrows, or moist leaf litter.
    (4) Dispersal Habitat. Accessible upland or riparian habitat within 
and between occupied or previously occupied sites that are located 
within 1 mi (1.6 km) of each other, and that support movement between 
such sites. Dispersal habitat includes various natural habitats, and 
altered habitats such as agricultural fields, that do not contain 
barriers (e.g., heavily traveled roads without bridges or culverts) to 
dispersal. Dispersal habitat does not include moderate- to high-density 
urban or industrial developments with large expanses of asphalt or 
concrete, nor does it include large lakes or reservoirs over 50 ac (20 
ha) in size, or other areas that do not contain those features 
identified in PCE 1, 2, or 3 as essential to the conservation of the 
species.

Special Management Considerations or Protections

    When designating critical habitat within the geographical area that 
is occupied at the time of listing, we identify the features that are 
essential to the conservation of the species and assess whether those 
features may require special management considerations or protection.
    The area designated as revised critical habitat will require some 
level of management to address current and future threats to the 
California red-legged frog and maintain the physical and biological 
features essential to the conservation of the species. Special 
management will be required in all units to ensure that aquatic and 
upland habitats provide abundant breeding and non-breeding areas, prey 
species, shelter, and connectivity within the landscape. The 
designation of critical habitat does not imply that areas outside of 
the final revised critical habitat designation do not play an important 
role in the conservation of the California red-legged frog. Areas 
outside the final revised critical habitat designation will continue to 
be subject to conservation actions implemented under section 7(a)(1) of 
the Act, regulatory protections afforded by the section 7(a)(2) 
jeopardy standard, and the prohibitions of section 9 of the Act. These 
protections and conservation tools will continue to contribute to 
recovery of the species.
    A detailed discussion of threats to the California red-legged frog 
and its habitat can be found in the final listing rule (May 23, 1996; 
61 FR 25813); the 2001 critical habitat designation (March 13, 2001; 66 
FR 14626); the 2006 critical habitat designation (April 13, 2006; 71 FR 
19243); the 2008 proposed revised critical habitat designation 
(September 16, 2008; 73 FR 53491); and the 2002 recovery plan (Service 
2002, pp. 1-173). Threats that may warrant special management 
considerations or protection of those features that define essential 
habitat in the appropriate quantity and spatial arrangement for the 
California red-legged frog include, but are not limited to: disease; 
direct and indirect impacts from some human recreational activities; 
flood control maintenance activities; water diversions; mining; 
dredging; sedimentation; water chemistry or temperature alterations; 
pesticide application; overgrazing; competition and predation by 
nonnative animal species; and habitat removal and alteration by 
urbanization, timber activities, and nonnative plant introduction. 
These threats may cause habitat alteration, degradation, or 
fragmentation and the direct or indirect loss of California red-legged 
frog eggs, juveniles, or adults or their habitat.

Criteria Used To Identify Critical Habitat

    As required by section 4(b)(2) of the Act, we use the best 
scientific data available in determining within the geographical area 
occupied at the time of listing the specific areas on which are found 
the features essential to the conservation of the California red-legged 
frog which may require special management considerations or protection, 
as well as in determining if any specific areas outside the 
geographical area occupied by the species are essential for the 
conservation of the California red-legged frog. We are designating 
critical habitat for the California red-legged frog within areas that 
we determined were occupied at the time of listing and that contain the 
physical and biological features essential to the conservation of the 
species. Lands are designated based on sufficient essential features 
being present to support one or more life processes.
    Based on the criteria used to identify critical habitat for the 
California red-legged frog, we believe those areas designated as 
critical habitat within the geographical area occupied by the species 
at the time of listing and those occupied areas identified subsequent 
to listing are sufficient to conserve the California red-legged frog. 
Our strategy for determining features essential to the conservation of 
the species was to target areas known to be occupied by the California 
red-legged frog at the time of listing, or known to possess high-
quality habitat likely to be occupied based on proximity to known 
occurrences, contiguous habitat, and dispersal capabilities of the 
California red-legged frog. We included large blocks of contiguous 
habitat that: (1) provide geographic distribution across the range of 
the species; (2) represent the full range of habitat and environmental 
variability the species occupies; (3) avoid conflict with existing 
commercial and residential development; (4) focus on public land, where 
available; and (5) where possible, overlap with other critical habitat 
designations. We believe the areas designated provide for the 
conservation of the California red-legged frog because the areas 
support large stable populations throughout the range of the species. 
The areas selected represent a distribution across the species' range 
and incorporate the northern and southern extent of the species within 
the coastal, interior coast, interior valleys, and Sierra Nevada 
Mountains. We believe the critical habitat units provide for 
connectivity and dispersal opportunities within, and in most cases 
between, units. Such opportunities for dispersal assist in maintaining 
the population structure and distribution of the California red-legged 
frog. We realize that there are areas outside of the designation that 
are included in the recovery plan and past critical habitat 
designations as having California red-legged frog occurrences or 
containing some of the primary constituent elements and that these 
areas may be utilized by the California red-legged frog for breeding, 
non-breeding activities, movement, and dispersal. However, as stated 
above, we believe the areas

[[Page 12837]]

designated in this rule provide for the conservation of the California 
red-legged frog. Therefore, we do not believe that we need to designate 
unoccupied areas for the species.
    We believe it is important to note that critical habitat 
designation is a different process than development of a recovery plan. 
A critical habitat designation is a specific regulatory action that 
defines specific areas as critical habitat in accordance with the 
statutory definition. A recovery plan is a guidance document, developed 
in cooperation with partners, which provides a roadmap with detailed, 
site-specific management actions to help conserve listed species and 
their ecosystems. The term ``essential'' as used in the recovery plan 
does not necessarily carry the same meaning as in the definition of 
critical habitat. The recovery plan provides important information 
about the species and the actions that are needed to bring about its 
recovery, while critical habitat identifies specific areas that are 
essential for the species' conservation.
    As required by section 4(b)(1)(A) of the Act, we used the best 
scientific data available in determining areas that contain the 
features essential to the conservation of the California red-legged 
frog, including the California red-legged frog recovery plan (Service 
2002, pp. 1-173), reports submitted during section 7 consultations and 
by biologists holding section 10(a)(1)(A) recovery permits, research 
published in peer-reviewed articles and presented in academic theses 
and agency reports, and regional Geographic Information Systems (GIS) 
coverages. We are not designating any areas outside the geographical 
area presently occupied by the species.
    We examined the core areas identified in the recovery plan and used 
these to focus our analysis of which areas to include in our critical 
habitat designation. We included a distribution of critical habitat 
within each core area that contains areas that were occupied at the 
time of listing and additional occupied areas identified as such 
subsequent to the time of listing. We found that the majority of newer 
occurrence records were within areas already known to support the 
California red-legged frog. We identified critical habitat units that 
have the highest likelihood to contain populations of the California 
red-legged frog based on (1) The presence of the defined PCEs; (2) the 
density of the California red-legged frog occurrences; (3) the kind, 
amount, and quality of habitat associated with those occurrences; and 
(4) the reasonable likelihood of habitat connectivity within and 
between units. The units contain the physical and biological features, 
as identified by the PCEs, in the appropriate quantity and arrangement 
essential to the conservation of the species.
    We considered several criteria in the selection of areas that 
contain the physical and biological features essential to the 
conservation of the California red-legged frog. We designated units 
throughout the geographical, elevational, and ecological distribution 
of the species that: (1) Maintain the current population structure 
across the species' range; (2) retain or provide for connectivity 
between breeding sites to allow for the continued existence of viable 
and essential metapopulations, despite fluctuations in the status of 
subpopulations; (3) possess large continuous blocks of occupied 
habitat, representing source populations or unique ecological 
characteristics; and (4) contain sufficient upland habitat around each 
breeding location to allow for sufficient survival and recruitment to 
maintain a breeding population over the long term. We then compared 
areas meeting these requirements to the core areas identified in the 
recovery plan for the species (Service 2002, pp. 1-173) and adjusted 
the number and distribution of units so that all core areas were 
represented in this final revised critical habitat designation.
    We delineated critical habitat boundaries using the following 
steps. We examined the range of the species as identified in our 2002 
recovery plan for the California red-legged frog (Service 2002, pp. 1-
173). We then determined the occupancy status of areas on the basis of 
report data compiled by the California Department of Fish and Game 
(CDFG) (CNDDB 2009). Initially, we used the 1996 final listing rule to 
establish those areas occupied at the time of listing. Subsequently, we 
used information on California red-legged frog population size, 
demographics, and biology to determine that additional areas were also 
occupied at the time of listing. Our designation does not include all 
areas where the California red-legged frog is known to occur. When 
determining which occupied areas contain the physical and biological 
features essential to the conservation of the species or the specific 
areas essential for the conservation of the species identified 
subsequent to those areas identified at the time of listing, we 
considered theories of metapopulation persistence, on-the-ground survey 
data, and the California red-legged frog's longevity. Bulger et al. 
(2003, pp. 85, 92) found more than 75 percent of California red-legged 
frogs are resident at permanent aquatic habitats over the course of a 
year, thereby providing local population stability. Survey data 
provided to us during the development of this and previous critical 
habitat rules show an average persistence of 19 years for California 
red-legged frog populations. Additionally, California red-legged frogs 
are considered long-lived with a minimum longevity of male and female 
California red-legged frogs between 8 and 10 years respectively 
(Jennings et al. 1992, p. 3), which also contributes to generational 
and metapopulation stability. For the above reasons, we believe that 
California red-legged frog populations located after the time of 
listing were actually present at the time of listing. This is because 
not all information on species locations existed or were available at 
that time (1996), and because new populations were unlikely to have 
been established in the interim period.
    We conducted a more detailed analysis of the occurrence data 
records by evaluating records where the exact site location was not 
identified or confirmed, and we removed those locations from our 
analysis. We then selected areas that were inhabited by source 
populations that are capable of maintaining their current population 
levels and providing individuals to recruit into subpopulations found 
in adjacent areas. We based this on the occurrence information or 
history for the site and persistence within the area. Additionally, we 
selected several areas that have ecological significance because of 
their unique features or settings, with the goal of representing the 
full range of the habitat variability and evolutionary adaptation in 
this species. These unique areas include locations on the periphery of 
the current range or that are representative of the varying habitats 
occupied by the California red-legged frog (i.e., coastal areas, 
interior coast, interior valleys, and montane habitats) to cover the 
full distribution of the species, and areas that provide connectivity 
among populations.
    Critical habitat units were delineated by creating approximate 
areas for the units by screen-digitizing polygons (map units) using 
ArcMap (Environmental Systems Research Institute, Inc.), a GIS program. 
The polygons were created by overlaying a 1-mi (1.6-km) radius around 
locations with occurrence records. We then used this distance as a 
guide for mapping the physical and biological features essential to the 
conservation of the species around the locations of California red-
legged frog populations (see Dispersal Habitat section). As stated

[[Page 12838]]

above, the California red-legged frog has been documented to disperse 
from ponds and streams a distance greater than 2.0 mi (3.2 km) (Bulger 
et al. 2003, p. 90). However, based on our review of the best 
scientific data available, we determined that the 2.0-mi (3.2-km) 
distance is likely near the maximum dispersal distance for the species 
during a single season, and that the 1-mi (1.6-km) distance is more 
reflective of the average dispersal distance for the California red-
legged frog (Rathbun et al. 1993, pp. 15, 16; Wright 1999, pp. 1, 2; 
Bulger et al. 2003, p. 90; Tatarian 2004, Table 9; Fellers and Kleeman 
2005, pp. 14-16; Fellers and Kleeman 2007, pp. 276-286). We recognize 
that upland habitat features will influence California red-legged frog 
movements in a particular landscape. As a result, we made adjustments 
to the upland areas of the critical habitat boundaries to include lands 
up to the watershed boundaries or habitat containing the PCEs beyond 
the 1-mi (1.6-km) distance (where appropriate) to aggregate clumps of 
occurrences and provide connectivity between occurrences. Whenever 
determinable, we removed areas not containing the PCEs from this 
revised designation, including agricultural, developed, disturbed, or 
fragmented lands.
    We evaluated the resulting units and refined the boundaries of the 
units within each watershed if it could be determined that certain 
areas within the units did not contain the primary constituent 
elements, were developed, or had dispersal barriers. We did not 
designate some areas because: (1) They do not contain sufficient PCEs 
to support one or more of the species' life processes; (2) the habitat 
within the area is highly degraded and is likely not restorable; (3) 
the area is small, highly fragmented, or isolated and likely provides 
little or no long-term conservation value; or (4) we determined that a 
sufficient amount of critical habitat had already been designated for 
an area. We applied this last criterion by evaluating the number of 
occurrence records for an area, the area's habitat quality or 
uniqueness, and the likelihood of persistence of the occurrences for an 
area.
    Finally, we focused on areas of high California red-legged frog 
abundance and areas needed to maintain connectivity between aquatic 
breeding habitats. We used the core areas identified in the recovery 
plan (Service 2002, pp.1-173) to assist in focusing the areas and 
extent of the critical habitat boundaries. We refined unit boundaries 
by using watershed boundaries from the State of California's CALWATER 
watershed classification system (version 2.2) using the smallest 
(planning watersheds) watershed designation. Visual inspection of 
mapped California red-legged frog occurrence records revealed un-
surveyed regions surrounded by surveyed regions (mostly adjacent to 
highly developed areas). Rather than designating critical habitat in a 
development fringe (areas adjacent to development), we designated in 
areas where fewer surveys may have been conducted but where California 
red-legged frogs are likely to occur based on nearby records and on 
similarity of habitat and presence of the physical and biological 
features essential to the conservation of the species. In areas where 
planning watersheds were large or hydrology was significantly altered, 
we used alternative structural, political, or topographic boundaries 
(e.g., streams, roads, county boundaries, ridgeline features, elevation 
contour lines) as the critical habitat boundary. These landscape 
features were used as critical habitat boundaries in these planning 
watershed areas because using a watershed boundary would have 
incorporated areas outside the species' dispersal distance or areas of 
unknown conservation value for the California red-legged frog. We made 
every attempt to connect localized California red-legged frog 
populations into single critical habitat units, if sufficient PCEs were 
present, in an attempt to combine similar habitats and to provide for 
better management of the unit.
    When determining critical habitat boundaries within this final 
rule, we made every effort to avoid including developed areas such as 
lands covered by buildings, pavement, and other structures because such 
lands lack essential features for the California red-legged frog. The 
scale of the maps we prepared under the parameters for publication 
within the Code of Federal Regulations may not reflect the exclusion of 
such developed lands. Any such structures and the land under them 
inadvertently left inside critical habitat boundaries shown on the maps 
of this final revised critical habitat are excluded by text in this 
final rule. Therefore, a Federal action involving these lands would not 
trigger section 7 consultation with respect to critical habitat and the 
requirement of no destruction or adverse modification, unless the 
specific action may affect adjacent critical habitat.

Final Critical Habitat Designation

    We are designating approximately 1,636,609 ac (662,312 ha) of 
critical habitat for the California red-legged frog in 48 units that we 
proposed as revised critical habitat. We have determined that all units 
were occupied at the time of listing. The critical habitat areas in 
Tables 1 and 2, and the unit descriptions below constitute our best 
assessment at this time of areas that meet the definition of critical 
habitat for the California red-legged frog. Table 1 lists those units 
we are excluding from critical habitat under section 4(b)(2) of the 
Act. Table 2 identifies the approximate area designated as critical 
habitat for the California red-legged frog by land ownership. Due to 
the conversion of GIS data from two different geographic projection 
zones (zone 10 and zone 11) and conversion of the data to acres and 
hectares, some rounding adjustments may be reflected in the area 
estimates.

management considerations or protection due to predation by nonnative 
species on egg masses, tadpoles, juveniles, or adults. Please see the 
Special Management Considerations or Protection section of this final 
rule for a detailed discussion of the threats to California red-legged 
frog habitat and potential management considerations.

RIV-1, Cole Creek

    We have excluded the lands containing features essential to the 
conservation of the California red-legged frog in Unit RIV-1 from 
critical habitat designation under section 4(b)(2) of the Act (see 
Application of Section 4(b)(2) of the Act section below).

Effects of Critical Habitat Designation

Section 7 Consultation

    Section 7(a)(2) of the Act requires Federal agencies, including the 
Service, to ensure that actions they fund, authorize, or carry out are 
not likely to jeopardize the continued existence of a listed species or 
destroy or adversely modify designated critical habitat. Decisions by 
the courts of appeals for the Fifth and Ninth Circuits have invalidated 
our definition of ``destruction or adverse modification'' (50 CFR 
402.02) (see Gifford Pinchot Task Force v. U.S. Fish and Wildlife 
Service, 378 F. 3d 1059 (9\th\ Cir. 2004) and Sierra Club v. U.S. Fish 
and Wildlife Service et al., 245 F.3d 434, 442 (5\th\ Cir. 2001)), and 
we do not rely on this regulatory definition when analyzing whether an 
action is likely to destroy or adversely modify critical habitat. Under 
the statutory provisions of the Act, we determine destruction or 
adverse modification on the basis of whether, with implementation of 
the proposed Federal action, the affected critical habitat would remain 
functional (or retain those physical and biological features that 
relate to the ability of the area to periodically support the species) 
to serve its intended conservation role for the species.
    If a species is listed or critical habitat is designated, section 
7(a)(2) of the Act requires Federal agencies to ensure that activities 
they authorize, fund, or carry out are not likely to jeopardize the 
continued existence of the species or to destroy or adversely modify 
its critical habitat. If a Federal action may affect a listed species 
or its critical habitat, the responsible Federal agency (action agency) 
must enter into consultation with us. As a result of this consultation, 
we document compliance with the requirements of section 7(a)(2) through 
our issuance of:
    (1) A concurrence letter for Federal actions that may affect, but 
are not likely to adversely affect, listed species or critical habitat; 
or
    (2) A biological opinion for Federal actions that may affect, and 
are likely to adversely affect, listed species or critical habitat.
    When we issue a biological opinion concluding that a project is 
likely to jeopardize the continued existence of a listed species or 
destroy or adversely modify critical habitat, we also provide 
reasonable and prudent alternatives to the project, if any are 
identifiable. We define ``Reasonable and prudent alternatives'' at 50 
CFR 402.02 as alternative actions identified during consultation that:
    (1) Can be implemented in a manner consistent with the intended 
purpose of the action;
    (2) Can be implemented consistent with the scope of the Federal 
agency's legal authority and jurisdiction;
    (3) Are economically and technologically feasible; and
    (4) Would, in the Director's opinion, avoid jeopardizing the 
continued existence of the listed species or destroying or adversely 
modifying critical habitat.
    Reasonable and prudent alternatives can vary from slight project 
modifications to extensive redesign or relocation of the project. Costs 
associated with implementing a reasonable and prudent alternative are 
similarly variable.
    Regulations at 50 CFR 402.16 require Federal agencies to reinitiate 
consultation on previously reviewed actions in instances where a new 
species is listed or critical habitat is subsequently designated that 
may be affected and the Federal agency has retained discretionary 
involvement or control over the action or such discretionary 
involvement or control is authorized by law. Consequently, Federal 
agencies may need to request reinitiation of consultation with us on 
actions for which formal consultation has been completed, if those 
actions with may affect subsequently listed species or designated 
critical habitat.
    Federal activities that may affect the California red-legged frog 
or its designated critical habitat will require section 7(a)(2) 
consultation under the Act. Activities on State, tribal, local, or 
private lands requiring a Federal permit (such as a permit from the 
U.S. Army Corps of Engineers (Corps) under section 404 of the Clean 
Water Act (33 U.S.C. 1251 et seq.) or a permit from us under section 
10(a)(1)(B) of the Act) or involving some other Federal action (such as 
funding from the Federal Highway Administration, Federal Aviation 
Administration, or the Federal Emergency Management Agency) are 
examples of agency actions that may be subject to the section 7(a)(2) 
consultation process. Federal actions not affecting listed species or 
critical habitat, and actions on State, tribal,

[[Page 12855]]

local, or private lands that are not federally funded, authorized, or 
permitted, do not require section 7(a)(2) consultations.

Application of the ``Adverse Modification'' Standard

    The key factor related to the adverse modification determination is 
whether, with implementation of the proposed Federal action, the 
affected critical habitat would continue to serve its intended 
conservation role for the species, or would retain its current ability 
for the primary constituent element(s) to be functionally established. 
Activities that may destroy or adversely modify critical habitat are 
those that alter the physical and biological features to an extent that 
appreciably reduces the conservation value of critical habitat for 
California red-legged frog. Generally, the conservation role of 
California red-legged frog critical habitat units is to support viable 
populations representative of each geographic area where the frog 
exists, as identified in the 2002 recovery plan and other information 
available to the Service.
    Section 4(b)(8) of the Act requires us to briefly evaluate and 
describe in any proposed or final regulation that designates critical 
habitat, activities involving a Federal action that may destroy or 
adversely modify such habitat, or that may be affected by such 
designation.
    Activities that, when carried out, funded, or authorized by a 
Federal agency, may affect critical habitat and therefore should result 
in consultation for the California red-legged frog include, but are not 
limited to:
    (1) Actions that significantly alter water chemistry or 
temperature. Such activities could include, but are not limited to: 
release of chemicals, biological pollutants, or heated effluents into 
the surface water or into connected groundwater at a point source or by 
dispersed release (non-point source). These activities alter water 
conditions beyond the tolerances of the California red-legged frog and 
result in direct or cumulative adverse effects to these individuals and 
their life cycles.
    (2) Actions that would significantly increase sediment deposition 
within a stream channel or pond or disturb upland foraging and 
dispersal habitat. Such activities could include, but are not limited 
to: excessive sedimentation from livestock overgrazing; road 
construction; commercial or urban development; channel alteration; 
timber harvest; off-road vehicle or recreational use; and other 
watershed and floodplain disturbances. These activities could eliminate 
or reduce the habitat necessary for the growth and reproduction of the 
California red-legged frog by increasing the sediment deposition to 
levels that would adversely affect a frog's ability to complete its 
life cycle.
    (3) Actions that would significantly alter channel/pond morphology 
or geometry. Such activities could include, but are not limited to: 
channelization; impoundment; road and bridge construction; development; 
mining; dredging; and destruction of riparian vegetation. These 
activities may lead to changes to the hydrologic functioning of the 
stream or pond by altering flow timing or duration, or altering water 
levels, which would degrade or eliminate the California red-legged frog 
or its habitat. These actions can also lead to increased sedimentation 
and degradation in water quality to levels that are beyond the 
tolerances of the California red-legged frog.
    (4) Actions that eliminate upland foraging or aestivating habitat, 
as well as dispersal habitat, for the California red-legged frog. Such 
activities could include, but are not limited to: road construction; 
commercial or urban development; timber harvest; off-road vehicle or 
recreational use; and other watershed and floodplain disturbances.
    (5) Actions that result in the introduction, spread, or 
augmentation of nonnative aquatic species in stream segments or ponds 
used by the California red-legged frog. Possible actions could include, 
but are not limited to: introduction of chytrid fungus or other 
diseases; fish or bullfrog stocking for sport; nonnative aquatic plant 
species for aesthetics; or other related actions. These activities 
could affect the growth and reproduction of the California red-legged 
frog by subjecting eggs, larvae, tadpoles, and adult California red-
legged frogs to increased predation pressure or could limit the amount 
of habitat available for the species, which would adversely affect the 
California red-legged frog's ability to complete its life cycle.
    Note that the scale of these activities is a crucial factor in 
determining whether they may directly or indirectly alter critical 
habitat to the extent that the value of the critical habitat for the 
survival and recovery of California red-legged frog would be 
appreciably diminished.
    If you have questions regarding whether specific activities may 
constitute adverse modification of critical habitat, contact the Field 
Supervisor of the appropriate Ecological Services Field Office (see FOR 
FURTHER INFORMATION CONTACT section).

Exemptions

Application of Section 4(a)(3) of the Act

    The Sikes Act Improvement Act of 1997 (Sikes Act) (16 U.S.C. 670a) 
required each military installation that includes land and water 
suitable for the conservation and management of natural resources to 
complete an integrated natural resources management plan (INRMP) by 
November 17, 2001. An INRMP integrates implementation of the military 
mission of the installation with stewardship of the natural resources 
found on the base. Each INRMP includes:
 An assessment of the ecological needs on the installation, 
including the need to provide for the conservation of listed species;
 A statement of goals and priorities;
 A detailed description of management actions to be implemented 
to provide for these ecological needs; and
 A monitoring and adaptive management plan.
    Among other things, each INRMP must, to the extent appropriate and 
applicable, provide for fish and wildlife management; fish and wildlife 
habitat enhancement or modification; wetland protection, enhancement, 
and restoration where necessary to support fish and wildlife; and 
enforcement of applicable natural resource laws.
    The National Defense Authorization Act for Fiscal Year 2004 (Pub. 
L. 108-136) amended the Act to limit areas eligible for designation as 
critical habitat. Specifically, section 4(a)(3)(B)(i) of the Act (16 
U.S.C. 1533(a)(3)(B)(i)) now provides: ``The Secretary shall not 
designate as critical habitat any lands or other geographical areas 
owned or controlled by the Department of Defense, or designated for its 
use, that are subject to an integrated natural resources management 
plan prepared under section 670a of this title, if the Secretary 
determines in writing that such plan provides a benefit to the species 
for which critical habitat is proposed for designation.''
    INRMPs developed by military installations located within the range 
of the California red-legged frog and which contain those features 
essential to the species' conservation were analyzed for exemption 
under the authority of section 4(a)(3) of the Act.

Previous Application of Section 4(a)(3) of the Act for Camp San Luis 
Obispo (Unit SLO-2) and Vandenberg Air Force Base (Units STB-2 and STB-
4)

    In the previous final critical habitat designation for the 
California red-legged

[[Page 12856]]

frog (71 FR 19243; April 13, 2006), we exempted Camp San Luis Obispo 
(CSLO) in San Luis Obispo County, and Vandenberg Air Force Base (VAFB) 
in Santa Barbara County, from the designation of critical habitat under 
section 4(a)(3) of the Act. Currently CSLO and VAFB do not have 
Service-approved INRMPs in place. Section 4(a)(3)(B)(i) of the Act 
requires that an approved INRMP be in place in order to qualify for an 
exemption. As a result of CSLO and VAFB not having Service approved 
INRMPs, we have reevaluated our previous decision and are not exempting 
CSLO and VAFB from portions of Unit SLO-2, Unit STB-2, and Unit STB-4 
under section 4(a)(3)(B)(i) of the Act. However, we have determined to 
exclude CSLO and VAFB from designated critical habitat under section 
4(b)(2) of the Act (see ``Application of Section 4(b)(2) - Impacts to 
National Security'' section below).

Exclusions Under Section 4(b)(2) of the Act

Application of Section 4(b)(2) of the Act

    Section 4(b)(2) of the Act states that the Secretary must designate 
and revise critical habitat on the basis of the best available 
scientific data after taking into consideration the economic impact, 
national security impact, and any other relevant impact of specifying 
any particular area as critical habitat. The Secretary may exclude an 
area from critical habitat if he determines that the benefits of such 
exclusion outweigh the benefits of specifying such area as part of the 
critical habitat, unless he determines, based on the best scientific 
data available, that the failure to designate such area as critical 
habitat will result in the extinction of the species. In making that 
determination, the legislative history is clear that the Secretary has 
broad discretion regarding which factor(s) to use and how much weight 
to give to any factor.
    In the following sections, we address a number of general issues 
that are relevant to the exclusions we are considering. In addition, we 
have conducted an economic analysis of the impacts of the proposed 
critical habitat designation and related factors, which was made 
available for public review and comment. Based on public comment on 
that document and the proposed designation itself, as well as the 
information in the final economic analysis, the Secretary may exclude 
from critical habitat areas different from those identified for 
possible exclusion in the proposed rule under the provisions of section 
4(b)(2) of the Act, up to and including all areas proposed for 
designation. This is also addressed in our implementing regulations at 
50 CFR 424.19.
Benefits of Designating Critical Habitat
    The process of designating critical habitat as described in the Act 
requires that the Service identify those lands within the geographical 
area occupied by the species at the time of listing on which are found 
the physical or biological features essential to the conservation of 
the species that may require special management considerations or 
protection, and those areas outside the geographical area occupied by 
the species at the time of listing that are essential to the 
conservation of the species. In identifying those lands, the Service 
must consider the recovery needs of the species, such that, on the 
basis of the best scientific data available at the time of designation, 
the habitat that is identified, if protected or managed appropriately, 
could provide for the survival and recovery of the species.
    The identification of areas that contain features essential to the 
conservation of the species and that if managed or protected, can 
provide for the recovery of a species, is beneficial. The process of 
proposing and finalizing a critical habitat rule provides the Service 
with the opportunity to determine the physical and biological features 
essential to the conservation of the species within the geographical 
area occupied by the species at the time of listing, as well as to 
determine other areas essential for the conservation of the species. 
The designation process includes peer review and public comment on the 
identified physical and biological features and areas. This process is 
valuable to land owners and managers in developing conservation 
management plans for identified areas, as well as any other occupied 
habitat or suitable habitat that may not be included in the areas the 
Service identifies as meeting the definition of critical habitat.
    The consultation provisions under section 7(a)(2) of the Act 
constitute the regulatory benefits of critical habitat. As discussed 
above, Federal agencies must consult with the Service on actions that 
may affect critical habitat and must avoid destroying or adversely 
modifying critical habitat. Federal agencies must also consult with us 
on actions that may affect a listed species and refrain from 
undertaking actions that are likely to jeopardize the continued 
existence of such species. The analysis of effects to critical habitat 
is a separate and different analysis from that of the effects to the 
species. Therefore, the difference in outcomes of these two analyses 
represents the regulatory benefit of critical habitat. For some 
species, and in some locations, the outcome of these analyses will be 
similar, because effects to habitat will often result in effects to the 
species. However, the regulatory standard is different, as the jeopardy 
analysis investigates the action's impact on survival and recovery of 
the species, while the adverse modification analysis investigates the 
action's effects on the designated habitat's contribution to 
conservation. This will, in many instances, lead to different results 
and different regulatory requirements. Thus, critical habitat 
designations may provide greater regulatory benefits to the recovery of 
a species than would listing alone.
    There are two limitations to the regulatory effect of critical 
habitat. First, a consultation is required only where there is a 
Federal nexus (an action authorized, funded, or carried out by any 
Federal agency)--if there is no Federal nexus the designation of 
private lands as critical habitat itself does not restrict any actions 
that destroy or adversely modify critical habitat. Second, the 
designation only limits destruction or adverse modification. By its 
nature, the prohibition on adverse modification is designed to ensure 
that the conservation role and function of those areas that contain the 
physical and biological features essential to the conservation of the 
species or of unoccupied areas that are essential for the conservation 
of the species are not appreciably reduced. Critical habitat 
designation alone, however, does not require property owners to 
undertake specific steps toward recovery of the species.
    Once an agency determines that consultation under section 7(a)(2) 
of the Act is necessary, the process may conclude informally when the 
Service concurs in writing that the proposed Federal action is not 
likely to adversely affect critical habitat. However, if we determine 
through informal consultation that adverse impacts are likely to occur, 
then formal consultation is initiated. Formal consultation concludes 
with a biological opinion issued by the Service on whether the proposed 
Federal action is likely to result in destruction or adverse 
modification of critical habitat.
    For critical habitat, a biological opinion that concludes in a 
determination of no destruction or adverse modification may contain 
discretionary conservation recommendations to minimize adverse effects 
to primary constituent elements, but it would not suggest the

[[Page 12857]]

implementation of any reasonable and prudent alternative. We suggest 
reasonable and prudent alternatives to the proposed Federal action only 
when our biological opinion results in an adverse modification 
conclusion.
    As stated above, the designation of critical habitat does not 
require that any management or recovery actions take place on the lands 
included in the designation. Even in cases where consultation is 
initiated under section 7(a)(2) of the Act, the end result of 
consultation is to avoid jeopardy to the species and/or adverse 
modification of its critical habitat, but not necessarily to manage 
critical habitat or institute recovery actions on critical habitat. 
Conversely, voluntary conservation efforts implemented through 
management plans institute proactive actions over the lands they 
encompass and are put in place to remove or reduce known threats to a 
species or its habitat and, therefore, implement recovery actions.
    Another benefit of including lands in critical habitat is that 
designation of critical habitat serves to educate landowners, State and 
local governments, and the public regarding the potential conservation 
value of an area. This helps focus and promote conservation efforts by 
other parties by clearly delineating areas of high conservation value 
for the affected species. In general, critical habitat designation 
always has educational benefits; however, in some cases, they may be 
redundant with other educational effects. For example, HCPs have 
significant public input and may largely duplicate the educational 
benefits of a critical habitat designation. Including lands in critical 
habitat also would inform State agencies and local governments about 
areas that could be conserved under State laws or local ordinances.
Conservation Partnerships on Non-Federal Lands
    Most federally listed species in the United States will not recover 
without cooperation of non-Federal landowners. More than 60 percent of 
the United States is privately owned (National Wilderness Institute 
1995, pp. 1-2), and at least 80 percent of endangered or threatened 
species occur either partially or solely on private lands (Crouse et 
al. 2002, p. 720). Stein et al. (1995, p. 400) found that only about 12 
percent of listed species were found almost exclusively on Federal 
lands (90 to 100 percent of their known occurrences restricted to 
Federal lands) and that 50 percent of federally listed species are not 
known to occur on Federal lands at all.
    Given the distribution of listed species with respect to land 
ownership, conservation of listed species in many parts of the United 
States is dependent upon working partnerships with a wide variety of 
entities and the voluntary cooperation of many non-Federal landowners 
(Wilcove and Chen 1998, p. 1407; Crouse et al. 2002, p. 720; James 
2002, p. 271). Building partnerships and promoting voluntary 
cooperation of landowners are essential to understanding the status of 
species on non-Federal lands, and are necessary to implement recovery 
actions such as reintroducing listed species, habitat restoration, and 
habitat protection.
    Many non-Federal landowners derive satisfaction from contributing 
to endangered species recovery. We promote these private-sector efforts 
through the Department of the Interior's Cooperative Conservation 
philosophy. Conservation agreements with non-Federal landowners (HCPs, 
safe harbor agreements, other conservation agreements, easements, and 
State and local regulations) enhance species conservation by extending 
species protections beyond those available through section 7 
consultations. We encourage non-Federal landowners to enter into 
conservation agreements, based on a view that we can achieve greater 
species conservation on non-Federal land through such partnerships than 
we can through regulatory methods (61 FR 63854).
    Many private landowners, however, are wary of the possible 
consequences of encouraging endangered species to their property. 
Mounting evidence suggests that some regulatory actions by the 
government, while well intentioned and required by law, can (under 
certain circumstances) have unintended negative consequences for the 
conservation of species on private lands (Wilcove et al. 1996, pp. 5-6; 
Bean 2002, pp.2-3; Conner and Mathews 2002, pp.1-2; James 2002, pp. 
270-271; Koch 2002, pp. 2-3; Brook et al. 2003, pp. 1639-1643). Many 
landowners fear a decline in their property value due to real or 
perceived restrictions on land-use options where threatened or 
endangered species are found. Consequently, harboring endangered 
species is viewed by many landowners as a liability. This perception 
results in anti-conservation incentives because maintaining habitats 
that harbor endangered species represents a risk to future economic 
opportunities (Main et al. 1999, pp. 1264-1265; Brook et al. 2003, pp. 
1644-1648).
    According to some researchers, the designation of critical habitat 
on private lands significantly reduces the likelihood that landowners 
will support and carry out conservation actions (Main et al. 1999, p. 
1263; Bean 2002, p. 2; Brook et al. 2003, pp. 1644-1648). The magnitude 
of this negative outcome is greatly amplified in situations where 
active management measures (such as reintroduction, fire management, 
and control of invasive species) are necessary for species conservation 
(Bean 2002, pp. 3-4). We believe that the judicious exclusion of 
specific areas of non-federally owned lands from critical habitat 
designations can contribute to species recovery and provide a superior 
level of conservation than critical habitat alone.
    The purpose of designating critical habitat is to contribute to the 
conservation of threatened and endangered species and the ecosystems 
upon which they depend. The outcome of the designation, triggering 
regulatory requirements for actions funded, authorized, or carried out 
by Federal agencies under section 7(a)(2) of the Act, can sometimes be 
counterproductive to its intended purpose on non-Federal lands. Thus 
the benefits of excluding areas that are covered by partnerships or 
voluntary conservation efforts can, in specific circumstances, be high.
Benefits of Excluding Lands with HCPs or other Management Plans
    The benefits of excluding lands with HCPs or other approved long-
term management plans from critical habitat designation include 
relieving landowners, communities, and counties of any additional 
regulatory burden that might be imposed as a result of the critical 
habitat designation. Many HCPs and other conservation plans take many 
years to develop, and upon completion, are consistent with the recovery 
objectives for listed species that are covered within the plan area. 
Many conservation plans also provide conservation benefits to unlisted 
sensitive species.
    A related benefit of excluding lands covered by approved HCPs and 
management plans that cover listed species from critical habitat 
designation is that it can make it easier for us to seek new 
partnerships with future plan participants, including States, counties, 
local jurisdictions, conservation organizations, and private 
landowners, which together can implement conservation actions that we 
would be unable to accomplish otherwise. HCPs often cover a wide range 
of species, including species that are not State and

[[Page 12858]]

Federally listed, and that would otherwise receive little protection 
from development. By excluding these lands, we preserve our current 
partnerships and encourage additional future conservation actions.
    We also note that permit issuance in association with HCP and 
Natural Communities Conservation Plan (NCCP)-HCP applications requires 
consultation under section 7 and section 10 of the Act, which would 
include the review of the effects of all HCP-covered activities that 
might adversely impact the species under a jeopardy standard, including 
possibly significant habitat modification (see definition of ``harm'' 
at 50 CFR 17.3), even without the critical habitat designation. 
Additionally, all other Federal actions that may affect the listed 
species still require consultation under section 7(a)(2) of the Act, 
and we review these actions for possibly significant habitat 
modification in accordance with the definition of harm referenced 
above.
    Information provided in the previous sections applies to all the 
following discussions of benefits of inclusion or exclusion of critical 
habitat.

Economic Analysis

    Section 4(b)(2) of the Act requires that we designate or revise 
critical habitat based upon the best scientific data available, after 
taking into consideration the economic impact, impact on national 
security, or any other relevant impact of specifying any particular 
area as critical habitat. In compliance with section 4(b)(2) of the 
Act, we have prepared an economic analysis (EA) of this final 
designation of critical habitat for the California red-legged frog. The 
final EA considers the potential economic effects of actions relating 
to the conservation of the California red-legged frog, including costs 
associated with sections 4, 7, and 10 of the Act, and including those 
attributable to designating critical habitat. It further considers the 
economic effects of protective measures taken as a result of other 
Federal, State, and local laws that aid habitat conservation for the 
California red-legged frog in essential habitat areas. The EA considers 
both economic efficiency and distributional effects. In the case of 
habitat conservation, efficiency effects generally reflect the 
``opportunity costs'' associated with the commitment of resources to 
comply with habitat protection measures (for example, lost economic 
opportunities associated with restrictions on land use). The EA also 
addresses how potential economic impacts are likely to be distributed, 
including an assessment of any local or regional impacts of habitat 
conservation and the potential effects of conservation activities on 
small entities and the energy industry. The information in the EA can 
be used by the Service and the Secretary to assess whether the effects 
of the designation might unduly burden a particular group or economic 
sector. Finally, the EA considers those costs that may occur in the 22 
years following the designation of critical habitat. The EA estimates 
the foreseeable economic impacts and the potential incremental costs as 
a result of the revised critical habitat designation; these are those 
costs attributed to critical habitat over and above those baseline 
costs coextensive with listing. The EA described economic impacts of 
California red-legged frog conservation efforts associated with the 
following categories of activity: (1) Residential and Commercial 
Development; (2) Water Management; (3) Agriculture; (4) Ranching/
Grazing; (5) Timber Harvest; (6) Transportation; (7) Fire Management; 
(8) Utility and Oil and Gas Pipeline Construction and Maintenance; and 
(9) Habitat and Vegetation Management.
    The pre-critical habitat designation (baseline) (1996-2008) costs 
associated with species conservation activities are estimated at $44 to 
$113 million on an annualized basis discounted at 7 percent. The EA 
estimated the total potential incremental economic impacts likely to 
result from the designation over the next 22 years (2009 to 2030) to be 
$159 million to $500 million ($14.4 to $45.2 million annualized) in 
present value terms using a 7 percent discount rate. Impacts to urban 
development represent approximately 90 percent of the incremental 
impacts. Impacts to agriculture activities account for 10 percent of 
the incremental costs due to the assumed establishment of no-pesticide 
use areas as part of the stipulated injunction as established by the 
Northern District Court of California for use of 66 pesticides (Center 
for Biological Diversity v. U.S. Environmental Protection Agency et 
al., Case No. C-02-1580-JSW (ND Ca. 2006)). This injunction and order 
will remain in effect for each of the 66 pesticides listed in the 
settlement until the Environmental Protection Agency (EPA) completes 
formal section 7(a)(2) consultation with the Service on the effects of 
each of the 66 active ingredients on the California red-legged frog.
    The EA did identify areas within the designation that had 
disproportionate costs when compared to other areas within the 
designation. We have reviewed the units that were associated with the 
disproportionate costs and have determined that only two units have the 
majority (over 30 percent) of the costs identified in the EA. Those 
units are Unit SLO-3 in San Luis Obispo County and Unit ALA-2 in 
Alameda County. However, due to the methodologies used in determining 
the costs to development that are associated with the designation of 
critical habitat, we are unable to specifically identify the exact 
areas where those costs may occur. Because the areas within the units 
where the high costs are attributed cannot be specifically identified, 
we have determined that it would be inappropriate to exercise our 
discretion under section 4(b)(2) of the Act to exclude portions of Unit 
SLO-3, and Unit ALA-2 from the designation. Because the EA did not 
identify any disproportionate costs that are likely to result from the 
remainder of the designation outside Unit SLO-3 and Unit ALA-2, we did 
not consider exercising our discretion to exclude any other areas from 
this designation of critical habitat for the California red-legged frog 
based on economic impacts. A copy of the final EA with supporting 
documents is included in our administrative record and may be obtained

Application of Section 4(b)(2) - Impacts to National Security

    Section 4(b)(2) of the Act allows the Secretary to exercise his 
discretion to exclude areas from critical habitat for reasons of 
national security if he determines the benefits of such an exclusion 
exceed the benefits of designating the area as critical habitat. 
However, this exclusion cannot occur if it will result in the 
extinction of the species concerned.
Camp San Luis Obispo
    Camp San Luis Obispo (CSLO) is a 5,612 ac (2,271 ha) State-owned 
training site managed by the California Army National Guard, which 
provides training grounds for National Guard, U.S. Army Reserve, and 
other Department of Defense troops, as well as law enforcement agencies 
and the U.S. State Department. CSLO currently trains approximately 
100,000 soldiers annually and supports overseas deployments to Iraq, 
Afghanistan, Kosovo, and other theaters.
    An Integrated Natural Resource Management Plan (INRMP) for CSLO was 
adopted by the California Army National Guard in 2001, but has not

[[Page 12859]]

been approved and signed by the Service. The Endangered Species 
Management Plan for California red-legged frogs, included as part of 
the INRMP, specifies conservation measures including: annual monitoring 
of California red-legged frog populations on CSLO lands; monitoring of 
grazing and training impacts on riparian and upland habitats; 
installation of cattle exclusion fencing to protect riparian habitat; 
bank stabilization and revegetation, and nonnative/invasive plant 
removal; a 3:1 mitigation ratio for riparian vegetation lost during 
construction and maintenance projects; and actively seeking funding for 
habitat improvement and conservation projects. California red-legged 
frog management efforts would continue to be implemented regardless of 
whether we designate CSLO as critical habitat.
    The Department of the Army, the National Guard Bureau, and the 
California Army National Guard stated in their comments that critical 
habitat designation on CSLO lands would impact national security. 
Designation of these lands could limit or restrict the amount of 
natural infrastructure available for ongoing and future mission 
execution and training needed for national security. The California 
Army National Guard expressed concern that critical habitat designation 
would impede troop readiness by requiring consultation for activities 
that may affect California red-legged frog critical habitat, and that 
delays or limitations to mission-essential training at CSLO directly 
affect the ability of soldiers to perform mission-essential tasks when 
deployed abroad or when assigned to National, State, local, and 
Homeland Security missions.

Benefits of Inclusion - Camp San Luis Obispo

    The benefit of including CSLO lands in this critical habitat 
designation is that designation can serve to educate the public 
regarding potential conservation value of the area and help focus 
conservation efforts. The California Army National Guard is well aware 
of the presence of California red-legged frogs on CSLO and the value of 
CSLO lands to the conservation of the California red-legged frog. The 
California Army National Guard currently implements management measures 
to conserve California red-legged frogs and their habitat. The 
California Army National Guard is actively working with the Service and 
the CDFG to develop an approved INRMP that will ensure conservation of 
this species on CSLO lands. Furthermore, we included all CSLO lands in 
the proposed designation, which itself reached a wide audience. 
Therefore, the educational benefits that might follow critical habitat 
designation (such as providing information to the California Army 
National Guard on areas important to the long-term conservation of this 
species) may have been already provided by consultation, development of 
the INRMP including the Endangered Species Management Plan, and 
proposing these areas as critical habitat.
    In light of the continued commitment by the California Army 
National Guard to manage their lands in a manner that promotes 
conservation of the California red-legged frog and because we will 
continue to complete consultations on activities that may impact 
California red-legged frogs, we believe designation of critical habitat 
would provide few, if any, additional regulatory and conservation 
benefits to the species beyond those that will result from continued 
species consultations.

Benefits of Exclusion - Camp San Luis Obispo

    The benefits of excluding approximately 5,612 ac (2,271 ha) of 
California Army National Guard lands are significant. The CSLO lands 
are used for realistic, intensive military training that provides 
soldiers with essential war-fighting skills that they utilize on the 
battlefield. As described above, designation of CSLO lands could limit 
or restrict the amount of natural infrastructure available for ongoing 
and future training needed for national security. Excluding these 
California Army National Guard lands from critical habitat designation 
will remove the potential impact that a designation of critical habitat 
could have on the military's ability to maintain our national security.

Benefits of Exclusion Outweigh Benefits of Inclusion - Camp San Luis 
Obispo

    We have determined that approximately 5,612 ac (2,271 ha) of the 
Camp San Luis Obispo National Guard Training Site (CSLO), located in 
Unit SLO-3, contain features essential to the conservation of the 
California red-legged frog, thereby meeting the definition of critical 
habitat under the Act. In the revised proposed rule to designate 
critical habitat we incorrectly identified approximately 5,902 ac 
(2,388 ha) owned by CSLO. On further review of the ownership of the 
lands for this designation within Unit SLO-3, we now correctly identify 
approximately 5,612 ac (2,271 ha) of land owned by CSLO that is subject 
to exclusion. In making our final decision with regard to CSLO lands, 
we considered several factors, including potential impacts to national 
security associated with a critical habitat designation as described by 
the Department of the Army, the National Guard Bureau, and the 
California Army National Guard; existing consultations; and 
conservation measures in place at this facility that benefit the 
California red-legged frog. We reviewed and evaluated the benefits of 
inclusion and benefits of exclusion for California Army National Guard 
lands in Unit SLO-3. We believe the benefits of designating these lands 
as California red-legged frog critical habitat are small, whereas the 
benefits of excluding these lands from critical habitat will result in 
the removal of potential impacts to national security. Therefore, we 
determined the benefits identified above of excluding approximately 
5,612 ac (2,271 ha) of CSLO lands from the critical habitat designation 
outweigh the benefits of including these lands. Under section 4(b)(2) 
of the Act, the Secretary is exercising his discretion to exclude all 
CSLO lands in SLO-3 from this final revised critical habitat 
designation as a result of impacts to national security.

Exclusion Will Not Result in Extinction of the Species - Camp San Luis 
Obispo

    We have determined that the exclusion of the CSLO lands from the 
final revised designation of critical habitat for the California red-
legged frog will not result in the extinction of the species. The 
benefits of excluding 5,612 ac (2,271 ha) of lands from critical 
habitat are more significant than the benefits of inclusion and include 
the removal of impacts to national security. While some loss of habitat 
for the California red-legged frog may occur with the continued 
activities on CSLO lands, we conclude that, due to the measures 
outlined in the California red-legged frog management component of the 
pending INRMP, and the continued commitment from the California Army 
National Guard to consult with us on projects that may adversely impact 
California red-legged frogs, these continued activities will not result 
in extinction of this species. The jeopardy standard of section 7 of 
the Act and routine implementation of conservation measures through the 
section 7 process provide assurances that the species will not go 
extinct as a result of this exclusion.
Vandenberg Air Force Base
    Vandenberg Air Force Base (VAFB) operates a 99,100 ac (40,104 ha) 
missile test base and aerospace center supporting west coast launch 
activities for the United States Air Force (Air

[[Page 12860]]

Force). The base extends along approximately 42 miles (68 km) of Santa 
Barbara County coastline and includes variable elevations and unique 
habitats that contribute to VAFB's distinct biological diversity. VAFB 
provides airspace for space launches, ballistic missile tests, 
aeronautical operations and military exercises.
    An INRMP for VAFB was developed by the Air Force, but has not been 
approved and signed by the Service. The draft INRMP has served as the 
foundation for implementation of conservation measures including: 
periodic surveys of California red-legged frog populations on VAFB, 
coordination with VAFB water quality staff to prevent degradation and 
contamination of California red-legged frog habitat, protection of 
various sites from human activities and grazing, prohibition of non-
native fish introduction into VAFB water bodies, and consultation with 
the Service on all actions that may affect California red-legged frogs 
on VAFB.
    The Air Force expressed concern that critical habitat designation 
on VAFB lands would impact national security and believes that 
designation of these lands as critical habitat would generally reduce 
the availability of unencumbered, natural infrastructure to support 
space and missile operations and essential maintenance activities. 
Additionally, the Air Force expressed concern that critical habitat 
designation would potentially delay short-notice, mission-critical 
activities that had not been previously analyzed in a consultation with 
the Service and that may affect critical habitat that has not been 
observed to be occupied by California red-legged frogs.

Benefits of Inclusion - Vandenberg Air Force Base

    One benefit of including VAFB lands in this critical habitat 
designation is the designation can educate the public regarding 
potential conservation value of the installation and may help focus 
conservation efforts. The Air Force is aware of the value of VAFB lands 
to the conservation of the California red-legged frog and currently 
implements management measures to conserve California red-legged frogs 
and their habitat. The Air Force is actively working with the Service 
and the CDFG to develop a revised INRMP that will ensure conservation 
of this species on VAFB lands. Further, we included all VAFB lands in 
the proposed designation, which itself reached a wide audience. 
Therefore, the educational benefits that might follow critical habitat 
designation (such as providing information to the military on areas 
important to the long-term conservation of this species) may have been 
already provided by consultation, development of the INRMP, and 
proposing VAFB as critical habitat.
    In light of the continued commitment by the Department of the Air 
Force to manage their lands in a manner that promotes conservation of 
the California red-legged frog and because we will continue to complete 
consultations on activities that may impact California red-legged 
frogs, we believe designation of critical habitat would provide few, if 
any, additional regulatory and conservation benefits to the species 
beyond those that will result from continued species consultations.

Benefits of Exclusion - Vandenberg Air Force Base

    The benefits of excluding approximately 24,913 ac (10,090 ha) of 
Air Force lands are significant. The VAFB lands are used to provide 
restricted airspace for space launches, ballistic missile tests, 
aeronautical operations, and military exercises. Designation of VAFB 
lands as critical habitat for California red-legged frogs would 
generally reduce the availability of unencumbered, natural 
infrastructure to support space missile operations and essential 
maintenance activities, and may potentially delay short-notice, 
mission-critical activities that were not previously analyzed in a 
consultation with the Service. Excluding these Air Force lands from the 
critical habitat designation will remove the potential impact that a 
designation of critical habitat could have on the military's ability to 
maintain our national security.

Benefits of Exclusion Outweigh Benefits of Inclusion - Vandenberg Air 
Force Base

    We determined that approximately 24, 913 ac (10,090 ha) of Air 
Force lands at VAFB, 23,912 ac (9,684 ha) located in Unit STB-2 and 
1,001 ac (405 ha) in STB-4, contain the features essential to the 
conservation of the California red-legged frog, and therefore meet the 
definition of critical habitat under the Act. In the unit description 
for Unit STB-2 in the revised proposed rule, we erroneously identified 
only 4,992 ac (1,992 ha) as being part of VAFB (73 FR 53510). We 
corrected this error, and we now identify approximately 24,913 ac 
(10,090 ha) as being part of VAFB and as a result subject to exclusion. 
In making our final decision with regard to these Air Force lands, we 
considered several factors including potential impacts to national 
security associated with critical habitat designation as described by 
the Air Force, existing consultations, and conservation measures in 
place at VAFB that benefit the California red-legged frog.
    We reviewed and evaluated the benefits of inclusion and benefits of 
exclusion for Air Force lands in Unit STB-2 and STB-4. We believe the 
benefits of designating these lands as California red-legged frog 
critical habitat are small, whereas the benefits of excluding these 
lands from critical habitat will result in the removal of potential 
impacts to national security. Therefore, we determined the benefits 
identified above of excluding approximately 24,913 ac (10,090 ha) of 
VAFB lands from the critical habitat designation outweigh the benefits 
of including these lands. Under section 4(b)(2) of the Act, we are 
excluding all Air Force lands in Unit STB-2 and STB-4 from this final 
revised critical habitat to prevent impacts to national security.

Exclusion Will Not Result in Extinction of the Species - Vandenberg Air 
Force Base

    We determined that the exclusion of the VAFB lands from the final 
revised critical habitat designation for the California red-legged frog 
will not result in the extinction of the species. The benefits of 
excluding 24,913 ac (10,090 ha) of lands from critical habitat are more 
significant than the benefits of inclusion and include the prevention 
of impacts to national security as determined by the Air Force. While 
some loss of habitat for the California red-legged frog may occur with 
the continued activities on VAFB lands, we conclude that, due to the 
measures outlined in the draft INRMP, and the continued commitment from 
the Air Force to consult with us on projects that may adversely impact 
California red-legged frogs, these continued activities would not 
jeopardize the continued existence of this species. The jeopardy 
standard of section 7 of the Act and routine implementation of 
conservation measures through the section 7 process provide assurances 
that the species will not go extinct as a result of this exclusion.

Application of Section 4(b)(2) - Other Relevant Impacts - Conservation 
Partnerships

    Section 4(b)(2) of the Act allows the Secretary to exclude areas 
from critical habitat for other relevant impacts if he determines that 
the benefits of such exclusion outweigh the benefits of specifying such 
area as part of critical habitat, unless he determines, based on the 
best scientific data available, that the failure to designate such area 
as critical habitat will result in the

[[Page 12861]]

extinction of the species. As discussed above in the Conservation 
Partnerships on Non-Federal Lands section, we believe that designation 
can negatively impact the working relationships and conservation 
partnerships we have formed with private landowners. The Service 
recognizes that 80 percent of endangered or threatened species occur 
either partially or solely on private lands (Crouse et al. 2002, p. 
270), and we will only achieve recovery of federally listed species 
with the cooperation of private landowners.
    In making the following exclusions, we evaluated the benefits of 
designating these non-Federal lands that may not have a Federal nexus 
for consultation while considering if our existing partnerships have 
resulted, or will result, in greater conservation benefits to the 
California red-legged frog and the physical or biological features 
essential to its conservation than a critical habitat designation. As 
discussed in the ``Benefits of Designating Critical Habitat'' section 
above, conservation partnerships that result in implementation of an 
HCP or other management plan that considers enhancement or recovery as 
the management standard often provide as much or more benefit than 
consultation on projects that may affect critical habitat (the primary 
benefit of a designation).
    In considering the benefits of including lands in a designation 
that are covered by a current HCP or other management plan, we evaluate 
a number of factors to help us determine the conservation benefit that 
the plan or program provides the species or its habitat:
    (1) Whether the plan is complete and provides protection from 
destruction or adverse modification of areas proposed as critical 
habitat;
    (2) Whether there is a reasonable expectation the conservation 
management strategies and actions will be implemented for the 
foreseeable future, based on past practices, written guidance, or 
regulations; and
    (3) Whether the plan provides conservation strategies and measures 
consistent with currently accepted principles of conservation biology.
    We balance the benefits of inclusion against the benefits of 
exclusion by considering the benefits that may accrue from 
consultations versus the benefits of preserving partnerships and 
encouraging development of additional HCPs and other conservation plans 
in the future.
    After consideration under section 4(b)(2) of the Act, the Secretary 
has determined to exercise his discretion to exclude the following 
specific areas from the final revised critical habitat for the 
California red-legged frog: Bonnie Doon Quarries Settlement Ponds HCP 
in Santa Cruz County (6 ac (3 ha)) (Unit SCZ-1); East Contra Costa 
County HCP and Natural Community Conservation Plan (NCCP) in Contra 
Costa County (75,767 ac (30,662 ha)) (Unit CCS-2); Western Riverside 
Multi-species HCP in Riverside County (4,069 ac (1,647 ha)) (Unit RIV-
1); East Bay Regional Park District lands in Contra Costa County 
(14,627 ac (5,919 ha)) (Unit CCS-2); Spivey Pond Management Area (BLM) 
in El Dorado County (54 ac (22 ha)) (Unit ELD-1); and Hearst Ranch 
Conservation Easement in San Luis Obispo County (34,777 ac (14,074 ha)) 
(Unit SLO-2).
Bonny Doon Quarries Settlement Ponds Habitat Conservation Plan (Bonny 
Doon HCP) (Unit SCZ-1)
    The Bonny Doon HCP encompasses approximately 6 ac (3 ha) of 
privatelyowned lands in the Santa Cruz Mountains near the town of 
Davenport, Santa Cruz County, California. California red-legged frogs 
are present in both of the watersheds (San Vicente Creek and Liddell 
Creek) where seven settlement ponds were constructed at the Bonny Doon 
Quarries. The Bonny Doon HCP was completed and finalized in 1998, 
concurrently with a final environmental assessment on the HCP under the 
National Environmental Policy Act (NEPA; 42 U.S.C. 4321 et seq.). We 
issued a non-jeopardy biological opinion under section 7 of the Act on 
the Bonny Doon HCP on July 29, 1999 (Service, 1-8-99-FW-70, 1999, pp. 
1-13). The Bonny Doon HCP contains measures to minimize and mitigate 
impacts to the California red-legged frog and its habitat from the 
quarry's operations, maintenance, and possible reclamation activities. 
The primary components of the minimization and mitigation include: 
developing and implementing an employee training program and community 
outreach program; conducting annual breeding and pre-activity surveys 
for California red-legged frogs at all settlement and mitigation ponds; 
avoiding or relocating California red-legged frog adults, tadpoles, and 
egg masses during maintenance activities; minimizing impacts of water 
releases to breeding populations of California red-legged frogs; 
inspecting the ground for California red-legged frogs that may be under 
vehicles prior to use; establishing a speed limit of 10 mi/hour (16 km/
hour) on roads within the operational area; using pesticides and 
herbicides that do not affect aquatic organisms and applying them in 
accordance with label precautions; disposing of all food-related trash 
in closed containers; controlling nonnative predators; and enhancing 
habitat suitability of the mitigation ponds and Settlement Pond 1 for 
the California red-legged frog. The Bonny Doon HCP and its accompanying 
implementing agreement, which delineates the responsibilities of the 
Service and the permittee for the implementation of the HCP, are 
designed to allow the operation and maintenance activities of up to 
seven settlement ponds and the reclamation of two additional settlement 
ponds totaling 4.9 ac (2 ha) in a manner that will result in 
conservation of the California red-legged frog and its habitat.
    Based on the reasoning below, the Secretary has determined to 
exercise his discretion to exclude approximately 6 ac (3 ha) of land 
from unit SCZ-1 in Santa Cruz County under section 4(b)(2) of the Act.

Benefits of Inclusion - Bonny Doon HCP

    The inclusion of approximately 6 ac (3 ha) of lands within the 
Bonny Doon HCP could be beneficial because it identifies lands that 
require management for conservation of California red-legged frogs. The 
process of proposing and finalizing the revised critical habitat rule 
provided the Service with the opportunity to evaluate and refine the 
features essential to the conservation of the species within the 
geographical area occupied by it at the time of listing, as well as to 
evaluate whether there are other areas essential for the conservation 
of the species. The designation process included peer review and public 
comment on the identified features and areas. This process is valuable 
to landowners and managers in developing conservation management plans 
for identified areas, as well as any other occupied habitat or suitable 
habitat that may not have been included in the Service's determination 
of essential habitat.
    The educational benefits of designation are small and largely 
redundant to those derived through conservation efforts currently being 
implemented in the approximately 6 ac (3 ha) of lands within the Bonny 
Doon HCP. The educational benefits of critical habitat designation 
derived through informing landowners and other members of the public of 
areas important for the long-term conservation of the California red-
legged frog may have been and continue to be achieved through: (1) 
Development and implementation of the Bonny Doon HCP, (2) the original 
critical habitat designation process in 2001 (66 FR

[[Page 12862]]

14626), and (3) publication of the revised critical habitat designation 
in 2006 (71 FR 19244).
    The consultation provisions under section 7 of the Act constitute 
the regulatory benefits of inclusion for critical habitat. As discussed 
above, Federal agencies must consult with us on actions that may affect 
critical habitat and must avoid destroying or adversely modifying 
critical habitat. There is some, albeit limited, potential for future 
activities within the lands we are excluding having a Federal nexus for 
the California red-legged frog as a result of actions by Federal 
agencies, such as the Army Corps of Engineers. Therefore, including 
this area may provide some regulatory benefits under section 7 of the 
Act.
    However, the Bonny Doon HCP addresses conservation issues from a 
coordinated, integrated perspective rather than a piecemeal, project-
by-project approach (as would occur on these lands under sections 7 of 
the Act absent this plan) and will arguably achieve more California 
red-legged frog conservation within the Bonny Doon HCP Plan Area than 
through section 7 consultations involving consideration of critical 
habitat. The PCEs required by California red-legged frogs will benefit 
from the conservation objectives and required measures outlined in the 
Bonny Doon HCP.
    In light of the conservation planning used in the development of 
the Bonny Doon HCP and the conservation that will occur under the HCP, 
we conclude that the potential regulatory benefit of designating this 
area in Unit SCZ-1 as critical habitat is minimal.

Benefits of Exclusion - Bonny Doon HCP

    HCPs foster a cooperative, coordinated approach to species 
protection and habitat conservation. The benefits of excluding HCP 
lands are: (1) Retaining and fostering the existing partnership and 
working relationship with the landowner(s) and other entities, and (2) 
encouraging future HCP development or development of other species/
habitat conservation plans. The benefits of excluding lands within 
approved plans that specifically benefit listed or sensitive species 
from critical habitat discussed above applies fully to the Bonny Doon 
HCP. Additionally, exclusion of an HCP (such as the Bonny Doon HCP) 
demonstrates our good faith effort and collaborative working 
relationships, which should encourage initiation and completion of 
other HCPs.
    We developed close partnerships with all participating entities 
through the development of the Bonny Doon HCP, which incorporates 
appropriate protections and management for the California red-legged 
frog, its habitat, and the features essential to the conservation of 
this species. By excluding 6 ac (3 ha) of lands in Unit SCZ-1 from 
designation, we are eliminating an essentially redundant layer of 
regulatory review for projects covered by the Bonny Doon HCP, helping 
to preserve our ongoing partnership with the plan participants, and 
encouraging new partnerships with other landowners and jurisdictions. 
These partnerships are critical for the conservation of California red-
legged frog.

Benefits of Exclusion Outweigh the Benefits of Inclusion -Bonny Doon 
HCP

    As discussed in the ``Benefits of Inclusion - Bonny Doon HCP'' 
section above, we believe the regulatory benefit of designating 
critical habitat on lands covered by the Bonny Doon HCP would be low. 
The Bonny Doon HCP addresses conservation issues from a coordinated, 
integrated perspective rather than a piecemeal project-by-project 
approach and will achieve more California red-legged frog conservation 
than we would achieve through multiple site-by-site, project-by- 
project, section 7 consultations involving consideration of critical 
habitat. We believe the conservation benefits for California red-legged 
frogs that would occur as a result of designating those 6 ac (3 ha) in 
Unit SCZ-1 as critical habitat (e.g., protection afforded through the 
section 7(a)(2) consultation process) is minimal compared to the 
overall conservation benefits for the species that will be realized 
through the implementation of the Bonny Doon HCP.
    Furthermore, the educational benefits of critical habitat 
designation, including informing the public of areas important for the 
long-term conservation of the species, are accomplished from material 
provided on our website and through notices of public comment periods 
associated with the original California red-legged frog critical 
habitat rule (66 FR 14626), the first revised critical habitat rule (71 
FR 19244), and the Bonny Doon HCP (Service 1998, pp. 1-23). Further, 
many educational benefits of critical habitat designation will be 
achieved through the overall designation, and will occur whether or not 
this particular location is designated. For these reasons, we believe 
that designating critical habitat has little benefit in areas covered 
by the Bonny Doon HCP.
    The exclusion of the Bonny Doon HCP lands from California red-
legged frog critical habitat will help preserve the partnerships that 
we developed for this HCP, which provides for California red-legged 
frog conservation. It may also help encourage new partnerships with 
other landowners and jurisdictions. These partnerships are critical for 
the conservation of California red-legged frog.
    We reviewed and evaluated the exclusion of 6 ac (3 ha) of private 
lands within the Bonny Doon HCP plan area from the final revised 
critical habitat designation for the California red-legged frog and 
determined that the benefits of excluding these lands in Unit SCZ-1 
outweigh the benefits of including them. As discussed above, the HCP 
will provide for preservation and management of habitat for and 
features essential to the conservation of the species.

Exclusion Will Not Result in Extinction of the Species - Bonny Doon HCP

    In keeping with our analysis and conclusion detailed in our 
biological opinion for the Bonny Doon HCP (Service, 1-8-99-FW-70, 1999, 
pp 1-13), we determined the exclusion of 6 ac (3 ha) of permittee-owned 
lands within the Bonny Doon HCP from this final critical habitat 
designation will not result in the extinction of the species. The 
amount of habitat we are excluding within the Bonny Doon HCP is only a 
minute fraction (less than 0.001 percent) of the amount of designated 
critical habitat in Unit SCZ-1. Additionally, the jeopardy standard of 
section 7 of the Act and routine implementation of conservation 
measures through the section 7 process provide assurances that the 
species will not go extinct as a result of this exclusion.
Western Riverside County Multiple Species Habitat Conservation Plan 
(Western Riverside County MSHCP) (Unit RIV-1)
    The Western Riverside County MSHCP is a large-scale, 
multijurisdictional HCP encompassing 1.26 million ac (510,000 ha) in 
western Riverside County and addresses 146 listed and unlisted 
``covered species,'' including the California red-legged frog. 
Participants in the Western Riverside County MSHCP include 14 cities in 
western Riverside County; the County of Riverside, including the 
Riverside County Flood Control and Water Conservation Agency (County 
Flood Control), Riverside County Transportation Commission, Riverside 
County Parks and Open Space District (County Parks), and Riverside 
County Waste Department; California Department of Parks and Recreation 
(State Parks); and the California Department of Transportation 
(Caltrans).

[[Page 12863]]

    The Western Riverside County MSHCP was designed to establish a 
multi-species conservation program that minimizes and mitigates the 
expected loss of habitat and associated incidental take of covered 
species. The Service issued an incidental take permit (TE-088609-0) 
under section 10(a)(1)(B) of the Act on June 22, 2004, to 22 permittees 
under the Western Riverside County MSHCP for a period of 75 years. This 
HCP requires establishment of approximately 153,000 ac (61,916 ha) of 
new conservation lands (Additional Reserve Lands) to complement the 
approximately 347,000 ac (140,426 ha) of pre-existing natural and open 
space areas defined by the Western Riverside County MSHCP as Public/
Quasi-Public (PQP) lands. These PQP lands include those under Federal 
ownership, primarily managed by the Forest Service and BLM, and also 
permittee-owned, open-space areas, primarily managed by State and 
County Parks. Collectively, the Additional Reserve Lands and PQP lands 
form the overall Western Riverside County MSHCP Conservation Area. The 
configuration of the 153,000 ac (61,916 ha) of Additional Reserve Lands 
is not mapped or precisely identified in the Western Riverside County 
MSHCP, but rather is based on textual descriptions within the bounds of 
a 310,000-ac (125,453-ha) Criteria Area and is interpreted as 
implementation of the Western Riverside County MSHCP takes place. All 
lands in Unit RIV-1 are located within the Western Riverside County 
MSHCP Plan Area.
    To address the primary threats to the California red-legged frog 
(i.e., habitat destruction and alteration) (61 FR 25813; May 23, 1996), 
the Western Riverside County MSHCP provides enhancement of habitat by 
removing or reducing these threats. Conservation objectives specific to 
the California red-legged frog in the MSHCP include the conservation of 
occupied and historical breeding habitat, and the conservation of 
intervening lands that provide for movement between core areas and 
upland habitat adjacent to occupied or suitable breeding habitat (Dudek 
and Associates, Inc. 2003, pp. A19-A20).
    The only known population of California red-legged frogs in the 
boundaries of the Western Riverside County MSCHP occurs along Cole 
Creek on the Santa Rosa Plateau. The occupied area along Cole Creek is 
entirely within the Santa Rosa Plateau Ecological Reserve, which is 
owned and managed by the CDFG. The management of the Santa Rosa Plateau 
Ecological Reserve includes measures that protect the habitat of the 
California red-legged frog and focus on restoration activities that 
benefit this species (Service 2004, p. 54). This area is included in 
Unit RIV-1, which consists of 4,069 ac (1,647 ha) of lands owned or 
controlled by the permittees. A total of 3,997 ac (1,618 ha) of these 
lands are currently conserved and referred to as PQP lands in the 
analysis of the Western Riverside County MSHCP, and 72 ac (29 ha) of 
lands that are privately owned. The provisions of the Western Riverside 
County MSHCP strengthen the management for the California red-legged 
frog and ensure that any projects that take place on the private land 
will not reduce the viability of the population within Unit RIV-1.
    Specifically, in the area proposed as critical habitat, the Western 
Riverside County MSHCP directs reserve managers of the PQP lands to 
maintain ecological processes within occupied habitat and appropriate 
new areas for the California red-legged frog (Dudek and Associates, 
Inc. 2003, pp. 5-13). Private lands included in Unit RIV-1 are in the 
survey area for the California red-legged frog, where 90 percent of 
areas that provide long-term conservation value for the species will be 
avoided until the conservation objectives for the California red-legged 
frog are met (Dudek and Associates, Inc. 2003, pp. 6-65-6-71). The 
Western Riverside County MSHCP indicates that the PQP reserve lands 
within Unit RIV-1 will be monitored to determine if successful 
reproduction is occurring (Dudek and Associates, Inc. 2003, p. 5-13). 
These lands will be managed to ensure that the threats to this species 
from altered hydrology, flood control, nonnative plant species, mining, 
human collecting, and predation will not negatively impact the 
population and that ecological processes necessary for the California 
red-legged frog breeding populations will be maintained (Dudek and 
Associates, Inc. 2003, p. 5-13). The Western Riverside County MSHCP 
preserves the habitat that supports identified core population(s) of 
this species and therefore contributes to recovery of this species in 
the Western Riverside County MSHCP area. The conservation objectives, 
required surveys, and adaptive management program for the California 
red-legged frog (and its PCEs) provided by the Western Riverside County 
MSHCP may exceed any conservation value provided as a result of 
regulatory protections that have been or may be afforded through 
critical habitat designation. Projects in these areas conducted or 
approved by Western Riverside County MSHCP permittees are subject to 
the conservation requirements of the Western Riverside County MSHCP. 
The Secretary has determined to exercised his discretion to exclude the 
entire approximately 4,069 ac (1,647 ha) of permittee-owned PQP and 
private lands from revised critical habitat designation within Unit 
RIV-1 (Cole Creek) under section 4(b)(2) of the Act.

Benefits of Inclusion - Western Riverside County MSHCP

    The benefits of inclusion in a critical habitat designation will 
provide little additional benefit to the California red-legged frog 
within the boundaries of the approved Western Riverside County MSHCP. 
The principal benefit of any designated critical habitat is that 
federally funded, permitted, or authorized activities that may affect 
critical habitat will require consultation under section 7 of the Act. 
Such consultations ensure that adequate protection is provided to avoid 
adverse modification or destruction of critical habitat. The approved 
Western Riverside County MSHCP covers the California red-legged frog 
and is designed to ensure the conservation of the species within the 
Plan area and incorporates special management and protection measures 
for California red-legged frog habitat within Plan boundaries. The 
Western Riverside County MSHCP's measures to protect the California 
red-legged frog and its habitat have undergone thorough evaluation in 
the section 7 consultation prior to approval of the Plan, and, 
therefore, there is no benefit of section 7 consultation by including 
these areas in critical habitat. Development and implementation of the 
Western Riverside County MSHCP has provided other important 
conservation benefits for the California red-legged frog, including the 
development of biological information to guide conservation efforts and 
assist in the species' recovery within the Plan area. The educational 
benefits of designating critical habitat, including informing the 
public of areas that are important to the conservation of listed 
species, are essentially the same as those that have occurred during 
the process of reviewing and approving the Western Riverside County 
MSHCP. Specifically, the Western Riverside County MSHCP involved public 
participation through public notices and public comment periods, prior 
to being approved. For these reasons, we believe that designation of 
critical habitat would provide little additional benefit in areas 
covered by the approved Western Riverside County MSHCP. Federal actions 
that may affect the California

[[Page 12864]]

red-legged frog will still require consultation under section 7 of the 
Act.

Benefits of Exclusion -- Western Riverside County MSHCP

    The benefits of excluding the Western Riverside County MSHCP from 
critical habitat designation include relieving landowners, communities, 
and portions of Riverside County of any additional regulatory burden 
that might be imposed by critical habitat. Many HCPs, particularly 
large regional HCPs, take many years to develop and, upon completion, 
become regional conservation plans that are consistent with the 
recovery objectives for listed species that are covered within the Plan 
area. Additionally, many of these HCPs provide conservation benefits to 
unlisted sensitive species. Imposing an additional regulatory review 
after an HCP is completed solely as a result of the designation of 
critical habitat may undermine conservation efforts and partnerships in 
many areas. In fact, it could result in the loss of species' benefits 
if participants abandon the voluntary HCP process. Designation of 
critical habitat within the boundaries of approved HCPs could also be 
viewed as a disincentive to those entities currently developing HCPs or 
contemplating them in the future. The benefits of excluding lands 
within approved plans that specifically benefit listed or sensitive 
species from critical habitat discussed above applies fully to the 
Western Riverside County MSHCP. A related benefit of excluding lands 
within approved HCPs that cover the California red-legged frog from the 
critical habitat designation is the continued ability to seek new 
partnerships with future HCP participants, including States, counties, 
local jurisdictions, conservation organizations, and private 
landowners, which together can implement conservation actions that we 
would be unable to accomplish otherwise. If lands within approved HCP 
plan areas are designated as critical habitat, it would likely have a 
chilling effect on our ability to establish new partnerships to develop 
HCPs, particularly large regional HCPs that involve numerous 
participants and address landscape-level conservation of the California 
red-legged frog and its habitat. By excluding the lands covered within 
the Western Riverside County MSHCP, we preserve our current 
partnerships and encourage additional conservation actions in the 
future.

Benefits of Exclusion Outweigh the Benefits of Inclusion - Western 
Riverside County MSHCP

    We believe that the regulatory benefit of designating critical 
habitat on private lands covered by the Western Riverside County MSHCP 
would be low and may hinder the effective implementation of the Plan. 
The Western Riverside County MSHCP addresses conservation issues from a 
coordinated, integrated perspective and will achieve better California 
red-legged frog conservation than would be achieved through multiple 
site-by-site, project-by-project, section 7 consultations involving 
consideration of critical habitat. The Western Riverside County MSHCP 
provides for the proactive monitoring and management of conserved lands 
(as previously described), reducing known threats to California red-
legged frog and its habitat.
    Conservation and management of California red-legged frog habitat 
is essential to the survival and recovery of this species. Such 
conservation needs are typically not addressed through the application 
of the statutory prohibition on adverse modification or destruction of 
critical habitat. The Western Riverside County MSHCP provides as much 
or more conservation benefit to the species than a consultation for 
critical habitat designation conducted under the standards required by 
the Ninth Circuit in the Gifford Pinchot decision. Furthermore, 
educational benefits that may be derived from a critical habitat 
designation are low in this case and largely redundant to the 
educational benefits achieved through the significant public, State, 
and local government input solicited and received during the 
development of the Western Riverside County MSHCP.
    We have developed close partnerships with the 22 Western Riverside 
County MSHCP permittees through the development of this regional HCP 
that incorporates appropriate protections and management of the 
physical and biological features essential to the conservation of this 
species. Those protections are consistent with the mandates under 
section 7 of the Act to avoid adverse modification or destruction of 
critical habitat and go beyond that prohibition by including active 
management and protection of essential habitat areas. By excluding 
these lands from designation, we are eliminating a largely redundant 
layer of regulatory review for a limited set of projects on non-Federal 
lands that are addressed by the Western Riverside County MSHCP, and we 
are helping to preserve our ongoing partnerships with the permittees 
and encouraging new partnerships with other landowners and 
jurisdictions. Those partnerships, and the landscape-level, multiple-
species conservation planning efforts they promote, are critical for 
the conservation of the California red-legged frog. Designating 
critical habitat on non-Federal lands within the Western Riverside 
County MSHCP could have a detrimental effect on our partnerships with 
the 22 Western Riverside County MSHCP permittees and could be a 
significant disincentive to the establishment of future partnerships 
and HCPs with other partners.
    We reviewed and evaluated the exclusion of 4,069 ac (1,647 ha) of 
private lands within the Western Riverside County MSHCP area from the 
final revised critical habitat designation for the California red-
legged frog and determined that the benefits of excluding these lands 
in Unit RIV-1 outweigh the benefits of including them. As discussed 
above, the HCP will provide for preservation and management of habitat 
for and features essential to the conservation of the species.

Exclusion Will Not Result in Extinction of the Species - Western 
Riverside County MSHCP

    In keeping with our analysis and conclusion detailed in our 
biological opinion for the Western Riverside County MSHCP (Service 
2004, p. 334), we do not believe that the exclusion of non-Federal 
lands that meet the definition of critical habitat within the Western 
Riverside County MSHCP plan area from the final designation of critical 
habitat for the California red-legged frog will result in the 
extinction of the species. Additionally, the jeopardy standard of 
section 7 of the Act and routine implementation of conservation 
measures through the section 7 process also provide assurances that the 
species will not go extinct as a result of this exclusion.
East Contra Costa County Habitat Conservation Plan and Natural 
Community Conservation Plan (East Contra Costa County HCP/NCCP) (Unit 
CCS-2)
    The East Contra Costa County HCP/NCCP was finalized on July 25, 
2007 (Service 2007b, pp. 1-6). Participants in this HCP/NCCP include 
the County of Contra Costa; the cities of Brentwood, Clayton, Oakley, 
and Pittsburg, California; and the Contra Costa Water District. The 
East Contra Costa County HCP encompasses the eastern portion of Contra 
Costa County from approximately west of Concord to Sand

[[Page 12865]]

Mound Slough and Clifton Court Forebay on the east. The East Contra 
Costa County HCP/NCCP is also a subregional plan under the State's NCCP 
process and was developed in cooperation with the CDFG. The East Contra 
Costa County HCP/NCCP includes areas where urban growth and development 
are expected to occur and has identified the California red-legged frog 
as a covered species. The East Contra Costa County HCP/NCCP 
specifically seeks to provide management and protection of the 
California red-legged frog through several conservation measures 
including: (1) Preserve between 24,455 to 29,467 ac (9,897 to 11,925 
ha) of upland foraging and dispersal habitat (not including additional 
lands identified in open space and parks); (2) preserve between 28 to 
36 wetted ac (11 to 15 wetted ha) of non-stream breeding habitat and 
between 85 to 98 mi (137 to 158 km) of stream breeding habitat; (3) 
create approximately 33 wetted ac (13 wetted ha) of ponds; (4) restore 
approximately 85 ac (34 ha) of perennial wetland complex; (5) preserve 
major habitat connections linking existing public lands; (6) 
incorporate a range of habitat and population management and 
enhancement measures; (7) fully mitigate the impacts of covered species 
and species, including the California red-legged frog; (8) maintain 
ecosystem processes; and (9) contribute to the recovery of covered 
species and species. These conservation measures will benefit 
California red-legged frog conservation by preserving and restoring 
existing wetland and upland habitat and creating new wetland habitat 
for the species. We expect the East Contra Costa County HCP/NCCP to 
provide substantial protection of the physical and biological features 
essential to the conservation of the species and provide special 
management considerations and protection of conservation lands. This 
will provide a greater level of management for the California red-
legged frog on these private lands than would designation of critical 
habitat.

Benefits of Inclusion - East Contra Costa County HCP/NCCP

    Critical habitat designation will provide little additional benefit 
to the California red-legged frog within the boundaries of the approved 
East Contra Costa County HCP/NCCP through the section 7 consultation 
process. The principal benefit of any designated critical habitat is 
that federally funded, permitted, or authorized activities that may 
affect critical habitat will require consultation under section 7 of 
the Act. Such consultations ensure that adequate protection is provided 
to avoid adverse modification or destruction of critical habitat. The 
approved East Contra Costa County HCP/NCCP covers the California red-
legged frog and is designed to ensure the conservation of the species 
within the Plan area and incorporates special management and protection 
measures for California red-legged frog habitat within Plan boundaries. 
The adequacy of the East Contra Costa County HCP/NCCP measures to 
protect the California red-legged frog and its habitat has undergone 
thorough evaluation in the section 7 consultation completed prior to 
approval of the Plan, and, therefore, there is no benefit of including 
these areas in critical habitat. Development and implementation of the 
East Contra Costa County HCP/NCCP has provided other important 
conservation benefits for the California red-legged frog, including the 
development of biological information to guide conservation efforts and 
assist in the species' recovery within the Plan area. The educational 
benefits of designating critical habitat, including informing the 
public of areas that are important to the conservation of listed 
species, are essentially the same as those that have occurred during 
the process of reviewing and approving the East Contra Costa County 
HCP/NCCP. Specifically, the East Contra Costa County HCP/NCCP involved 
public participation through public notices and public comment periods, 
prior to being approved. For these reasons, we believe that designation 
of critical habitat would provide little additional benefit in areas 
covered by the approved East Contra Costa County HCP/NCCP. Federal 
actions that may affect the California red-legged frog will still 
require consultation under section 7 of the Act.

Benefits of Exclusion -- East Contra Costa County HCP/NCCP

    The benefits of excluding the East Contra Costa County HCP/NCCP 
from critical habitat designation include relieving landowners, 
communities, and portions of eastern Contra Costa County of any 
additional regulatory burden that might be imposed by critical habitat. 
Many HCPs, particularly large regional HCPs, take many years to develop 
and, upon completion, become regional conservation plans that are 
consistent with the recovery objectives for listed species that are 
covered within the Plan area. Additionally, many of these HCPs provide 
conservation benefits to unlisted sensitive species. Imposing an 
additional regulatory review after a HCP is completed solely as a 
result of the designation of critical habitat may undermine 
conservation efforts and partnerships in many areas. In fact, it could 
result in the loss of species' benefits if participants abandon the 
voluntary HCP process. Designation of critical habitat within the 
boundaries of approved HCPs could also be viewed as a disincentive to 
those entities currently developing HCPs or contemplating them in the 
future. The benefits of excluding lands within approved plans that 
specifically benefit listed or sensitive species from critical habitat 
discussed above applies fully to the East Contra Costa County HCP/NCCP. 
A related benefit of excluding lands within approved HCPs that cover 
the California red-legged frog from the critical habitat designation is 
the continued ability to seek new partnerships with future HCPs 
participants, including States, counties, local jurisdictions, 
conservation organizations, and private landowners, which together can 
implement conservation actions that we would be unable to accomplish 
otherwise. If lands within approved HCPs plan areas are designated as 
critical habitat, it would likely have a chilling effect on our ability 
to establish new partnerships to develop HCPs, particularly large 
regional HCPs that involve numerous participants and address landscape 
level conservation of the California red-legged frog and its habitat. 
By excluding the lands covered within the East Contra Costa County HCP/
NCCP, we preserve our current partnerships and encourage additional 
conservation actions in the future.

Benefits of Exclusion Outweigh the Benefits of Inclusion

    We believe that the regulatory benefit of designating critical 
habitat on private lands covered by the East Contra Costa County HCP/
NCCP would be low and may hinder the effective implementation of the 
plan. The East Contra Costa County HCP/NCCP addresses conservation 
issues from a coordinated, integrated perspective and will achieve 
better California red-legged frog conservation than would be achieved 
through multiple site-by-site, project-by-project, section 7 
consultations involving consideration of critical habitat. East Contra

    We have developed close partnerships with the eight East Contra 
Costa County HCP/NCCP permittees through the development of this 
regional HCP/NCCP that incorporates appropriate protections and 
management of the physical and biological features essential to the 
conservation of this species. Those protections are consistent with the 
mandates under section 7 of the Act to avoid adverse modification or 
destruction of critical habitat and go beyond that prohibition by 
including active management and protection of essential habitat areas. 
By excluding these lands from designation, we are eliminating a largely 
redundant layer of regulatory review for a limited set of projects on 
non-Federal lands that are addressed by the East Contra Costa County 
HCP/NCCP, and we are helping to preserve our ongoing partnerships with 
the permittees and encouraging new partnerships with other landowners 
and jurisdictions. Those partnerships, and the landscape-level, 
multiple-species conservation planning efforts they promote, are 
critical for the conservation of the California red-legged frog. 
Designating critical habitat on non-Federal lands within the East 
Contra Costa County HCP/NCCP could have a detrimental effect to our 
partnerships with the eight East Contra Costa County HCP/NCCP 
permittees and could be a significant disincentive to the establishment 
of future partnerships and HCPs with other partners.
    As a result of the specific conservation measures in the Plan being 
implemented for the California red-legged frog, the Secretary has 
determined to exercise his discretion under section 4(b)(2) of the Act 
to exclude approximately 75,767 ac (30,662 ha) of land that will 
receive protection and the special management they require through 
funding mechanisms that will be implemented under the East Contra Costa 
County HCP/NCCP.

Exclusion Will Not Result in Extinction of the Species

    In keeping with our analysis and conclusion detailed in our 
biological opinion for the East Contra Costa County HCP/NCCP (Service 
2007c, pp. 1-189), we do not believe that the exclusion of non-Federal 
lands that meet the definition of critical habitat within the East 
Contra Costa County HCP/NCCP plan area from the final designation of 
critical habitat for the California red-legged frog will result in the 
extinction of the species. Additionally, the jeopardy standard of 
section 7 of the Act and routine implementation of conservation 
measures through the section 7 process also provide assurances that the 
species will not go extinct as a result of this exclusion.
Other Conservation Plans
East Bay Regional Park District Lands (EBRPD) (Unit CCS-2)
    The East Bay Regional Park District (EBRPD) manages 65 regional 
parks, recreation areas, wilderness, shorelines, preserves, and land 
bank areas covering over 95,000 ac (34,446 ha) in Alameda and Contra 
Costa Counties. The EBRPD Board of Directors adopted the EBRPD Plan on 
December 17, 1996, under Resolution Number 1996-12-349 (EBRPD 1997, pp. 
1-87). The EBRPD Plan provides for monitoring and conservation of rare, 
threatened, and endangered taxa, including the California red-legged 
frog. The Service issued an incidental take permit (817400) under 
section 10(a)(1)(B) of the Act to the EBRPD and they have been actively 
conducting California red-legged frog surveys and research over the 
last 15 years. In 1996, 2000, 2004, and most recently in 2007 (Bobzien 
and DiDonato 2007, pp. 1-87), EBRPD staff conducted California red-
legged frog surveys across all park lands for the purpose of population 
trend monitoring and habitat assessment. Research conducted by EBRPD 
has also focused on California red-legged frog habitat requirements, 
tolerances related to water quality, adult and juvenile movements, and 
the effect of livestock grazing on habitat and frog reproduction. EBRPD 
provides educational outreach through park interpretive programs and 
presentation of California red-legged frog research findings at 
scientific conferences and in peer-reviewed journals. Habitat 
restoration and nonnative predator control are special management 
actions the EBRPD uses for the conservation of the California red-
legged frog. The majority of the EBRPD land holdings are protected and 
managed as natural parklands, thereby providing protection for the 
physical and biological features essential to the conservation of the 
California red-legged frog. Conservation efforts including conserving, 
enhancing, and restoring rare, threatened, endangered, or locally 
important species of plants and animals and their habitats take 
precedence over other park activities if EBRPD activities are 
determined to have a significant adverse effect (change in any of the 
physical conditions within the area affected by a potential activity) 
on these resources (EBRPD 1997, pp. 1-83). As identified in their 
Master Plan, the EBRPD will accomplish this by using scientific 
research, field experience, and other proven methodologies. Populations 
of listed species will be monitored through periodic observations of 
their condition, size, habitat, reproduction, and distribution (EBRPD 
1997, p. 20).
    We expect the EBRPD to provide substantial protection of the 
physical and biological features essential to the conservation of the 
California red-legged frog on EBRPD lands within unit CCS-2. We expect 
the EBRPD to provide a greater level of management for the California 
red-legged frog on EBRPD lands than would designation of critical 
habitat on private lands. Moreover, inclusion of these non-Federal 
lands as critical habitat would not necessitate additional management 
and conservation activities over and above those already in place by 
the EBRPD. We do not anticipate any action on these lands would destroy 
or adversely modify the areas that meet the definition of critical 
habitat. Therefore, we do not expect that including those areas in the 
final designation will lead to any changes to actions on the 
conservation lands to avoid destroying or adversely modifying that 
habitat.

Benefits of Inclusion - East Bay Regional Park District Lands

    Critical habitat designation will provide little additional benefit 
to the California red-legged frog within the areas owned and managed by 
the EBRPD. The principal benefit of any designated critical habitat is 
that federally-\ funded, permitted, or authorized activities that may 
affect critical habitat will require consultation under section 7 of 
the Act. Such consultations ensure that adequate protection is provided 
to avoid adverse modification or destruction of critical habitat. The 
approved EBRPD Master Plan covers the California red-legged

[[Page 12867]]

frog and is designed to ensure the conservation of the species within 
the Plan area and incorporates special management and protection 
measures for California red-legged frog habitat within Plan boundaries. 
The adequacy of the EBRPD measures to protect the California red-legged 
frog and its habitat has undergone thorough public evaluation prior to 
approval of the Plan. Development and implementation of the EBRPD 
Master Plan has provided other important conservation benefits for the 
California red-legged frog, including the development of biological 
information to guide conservation efforts and assist in the species' 
recovery within the Plan area. The educational benefits of designating 
critical habitat, including informing the public of areas that are 
important to the conservation of listed species, are essentially the 
same as those that have occurred during the public involvement process 
of reviewing and approving the EBRPD Master Plan. Specifically, the 
EBRPD Master Plan involved public participation through public notices 
and public comment periods, active participation of the District's 
citizen-based Park Advisory Committee (PAC) and with extensive review 
and comment from the community prior to being approved. For these 
reasons, we believe that designation of critical habitat would provide 
little additional benefit in areas covered by the approved EBRPD Master 
Plan. Any actions that may affect the California red-legged frog will 
still require consultation under section 7 or section 10 of the Act.

Benefits of Exclusion -- East Bay Regional Park District Lands

    The benefits of excluding the EBRPD Master Plan from critical 
habitat designation include relieving landowners, communities, and 
portions of eastern Contra Costa County of any additional regulatory 
burden that might be imposed by critical habitat. Many such plans, 
particularly large regional plans such as this, take many years to 
develop and, upon completion, are consistent with the recovery 
objectives for listed species that are covered within the plan area. 
Additionally, many of these plans provide conservation benefits to 
unlisted sensitive species. Imposing an additional regulatory review 
after such as plan that specifically identifies measures to protect and 
conserve listed and other sensitive species is completed solely as a 
result of the designation of critical habitat may undermine 
conservation efforts and partnerships in many areas. In fact, it could 
result in the loss of species' benefits if participants abandon 
currently implemented conservation activities. Designation of critical 
habitat within the boundaries of approved plan could also be viewed as 
a disincentive to those entities currently developing similar plans or 
contemplating them in the future. The benefits of excluding lands 
within approved plans that specifically benefit listed or sensitive 
species from critical habitat discussed above applies fully to the 
EBRPD Master Plan. A related benefit of excluding lands within approved 
plans that cover the California red-legged frog from the critical 
habitat designation is the continued ability to seek new partnerships 
with future participants, including States, counties, local 
jurisdictions, conservation organizations, and private landowners, 
which together can implement conservation actions that we would be 
unable to accomplish otherwise. If lands within approved plan areas are 
designated as critical habitat, it would likely have a chilling effect 
on our ability to establish new partnerships to develop other such 
plans or HCPs, particularly large regional plans or HCPs that involve 
numerous participants and address landscape level conservation of the 
California red-legged frog and its habitat. By excluding the lands 
covered within the EBRPD Master Plan within eastern Contra Costa 
County, we preserve our current partnerships and encourage additional 
conservation actions in the future.

Benefits of Exclusion Outweigh the Benefits of Inclusion

    We believe that the regulatory benefit of designating critical 
habitat on lands managed and owned by the EBRPD would be low and may 
hinder the effective implementation of the 1997 EBRPD Master Plan. The 
EBRPD Master Plan addresses conservation issues from a coordinated, 
integrated perspective and will achieve better California red-legged 
frog conservation than would be achieved through multiple site-by-site, 
project-by-project, section 7 consultations involving consideration of 
critical habitat. The EBRPD Master Plan provides for the proactive 
monitoring and management of conserved lands (as previously described), 
reducing known threats to California red-legged frog and its habitat.
    Conservation and management of viable California red-legged frog 
habitat is essential to the survival and recovery of this species. Such 
conservation needs are typically not addressed through the action-by-
action application of the statutory prohibition on adverse modification 
or destruction of critical habitat. The implementation of the EBRPD 
Master Plan provides as much or more conservation benefit to the 
species than a consultation for critical habitat designation conducted 
under the standards required by the Ninth Circuit in the Gifford 
Pinchot decision. Furthermore, educational benefits that may be derived 
from a critical habitat designation are low in this case and largely 
redundant to the educational benefits achieved through the significant 
public, State, and local government input solicited and received during 
the development of the EBRPD Master Plan.
    For these reasons, we believe that designating critical habitat has 
little benefit in areas covered by the identified EBRPD lands. As a 
result, the Secretary has determined to exercise his discretion to 
exclude those EBRPD lands totaling approximately 14,627 ac (5,919 ha) 
within Unit CCS-2 from the designation of critical habitat under 
section 4(b)(2) of the Act.

Exclusion Will Not Result in Extinction of the Species

    The exclusion of East Bay Regional Park lands within Unit CCS-2 
would not result in the extinction of the California red-legged frog. 
Actions that may adversely affect the species are expected to have a 
Federal nexus, and would thus undergo a consultation with the Service 
under section 7 of the Act. The jeopardy standard of section 7 of the 
Act, and routine implementation of conservation measures through the 
section 7 process, provide assurance that the species will not go 
extinct. Additionally, the species is protected from the take 
prohibitions under section 9 of the Act. The exclusion leaves these 
protections unchanged from those that would exist if the excluded areas 
were designated as critical habitat.
    We do not believe that this exclusion would result in the 
extinction of the species because: (1) The species occurs on lands 
protected and managed either explicitly for the species, or indirectly 
through more general objectives to protect natural values. This factor 
along with the other protections provided under the Act for these lands 
absent designating them as critical habitat, combined with protections 
afforded the species by the remaining critical habitat designation for 
the species, leads us to find that exclusion of these lands will not 
result in extinction of the California red-legged frog; and (2) the 
species is found in other areas and the EBRPD Plan provides for 
monitoring and conservation of rare, threatened, and endangered taxa, 
including the California red-legged frog. EBRPD has been actively 
conducting California red-

[[Page 12868]]

legged frog surveys and research over the last 15 years. Nearly 90 
percent of the EBRPD land holdings are protected and managed as natural 
parklands, thereby providing protection for the PCEs (Bobzien 2005, pp. 
1-2), and conservation efforts take precedence over other park 
activities if EBRPD activities are determined to have a significant 
adverse effect on rare, threatened, or endangered taxa (EBRPD 1997, pp. 
1-83).
Spivey Pond Management Area (SPMA) (Unit ELD-1)
    The SPMA encompasses 54 ac (22 ha) of BLM-owned lands surrounding 
Spivey Pond in El Dorado County, California. Spivey Pond is one of five 
known extant California red-legged frog breeding populations in the 
Sierra Nevada foothills. In 1997, a population of reproducing 
California red-legged frogs was discovered in Spivey Pond on the north 
fork of Webber Creek. The previously confirmed sightings of a 
California red-legged frog in the Webber Creek watershed were in 1972 
and 1975. At the time of discovery, the Spivey Pond parcel was 
privately owned and slated for timber harvest and subdivision 
development. The Service urged the American River Conservancy (ARC) to 
initiate negotiations with the owners of the Spivey Pond for purchase 
of the property. With financial assistance from the Service and the 
U.S. Bureau of Reclamation (USBR), ARC succeeded in purchasing the 54 
ac (22 ha) Spivey Pond parcel on April 28, 1998. Additional grant 
funding from the National Fish and Wildlife Foundation was received on 
September 15, 1998, which allowed for initial pond stabilization and 
restoration work.
    On May 3, 1999, all preliminary acquisition and restoration 
activities were completed, and the parcel was transferred to the BLM to 
be managed as a wildlife reserve specifically for the benefit of the 
California red-legged frog. We issued a non-jeopardy biological opinion 
for development of a new breeding pond for the species (Service File 1-
1-03-F-0289) on March 4, 2004. A management plan for the California 
red-legged frog was finalized by BLM, the Service, Forest Service (El 
Dorado National Forest), USBR, CDFG, ARC, El Dorado County, and the El 
Dorado Irrigation District in July 2004 (BLM 2004, pp. 1-26). The 
Management Plan for the SPMA consists of six management objectives 
specifically for the conservation of the California red-legged frog 
including: (1) Control of bullfrogs and predatory fish; (2) monitoring 
of water quality for potential contaminants; (3) maintenance of the 
pond's integrity and habitat/water quality; (4) creation and management 
of additional California red-legged frog breeding habitat; (5) 
promotion of research and maintenance of a GIS database; (6) and 
providing input for watershed level planning and activities that may 
benefit Spivey Pond (BLM 2004, pp. 1-26).

Benefits of Inclusion - Spivey Pond Management Area

    The approved Spivey Pond Management Plan covers the California red-
legged frog and is designed to ensure the conservation of the species 
within the Plan area and incorporates special management and protection 
measures for California red-legged frog habitat within Plan boundaries. 
The Spivey Pond Management Plan's measures to protect the California 
red-legged frog and its habitat underwent thorough evaluation by the 
Service and other stakeholders prior to approval of the Plan. 
Development and implementation of the Spivey Pond Management Plan has 
provided other important conservation benefits for the California red-
legged frog, including the development of biological information to 
guide conservation efforts and assist in the species' recovery within 
the Plan area. The educational benefits of designating critical 
habitat, including informing the public of areas that are important to 
the conservation of listed species, are essentially the same as those 
that have occurred during the public involvement process of designating 
critical habitat in 2006, and again within this designation in 2009. In 
addition, Federal actions that may affect the California red-legged 
frog will still require consultation under section 7 of the Act. For 
these reasons, we believe that designation of critical habitat would 
provide little additional benefit in areas covered by the approved 
Spivey Pond Management Plan.

Benefits of Exclusion - Spivey Pond Management Area

    The benefits of excluding the Spivey Pond Management Plan from 
critical habitat designation include relieving the BLM of any 
additional regulatory burden that might be imposed by critical habitat. 
Imposing an additional regulatory review after such a plan that 
specifically identifies measures to protect and conserve the California 
red-legged frog is completed, solely as a result of the designation of 
critical habitat, may undermine the conservation efforts and 
partnerships developed during the development and implementation of 
this Plan. In fact, it could result in the loss of species' benefits if 
participants abandon currently implemented conservation activities. 
Designation of critical habitat within the boundaries of the approved 
Plan could also be viewed as a disincentive to those entities currently 
developing similar plans or contemplating them in the future. The 
previously discussed benefits of excluding lands within approved plans 
that specifically benefit listed or sensitive species from critical 
habitat apply fully to the Spivey Pond Management Plan. A related 
benefit of excluding lands within approved plans that cover the 
California red-legged frog from the critical habitat designation is the 
continued ability to seek new partnerships with future participants, 
including States, counties, local jurisdictions, conservation 
organizations, and private landowners, which together can implement 
conservation actions that we would be unable to accomplish otherwise. 
If lands within approved plan areas are designated as critical habitat, 
it would likely have a chilling effect on our ability to establish new 
partnerships to develop other such plans or HCPs that involve numerous 
participants. By excluding the lands covered within the Spivey Pond 
Management Plan within El Dorado County, we preserve our current 
partnerships and encourage additional conservation actions in the 
future.

Benefits of Exclusion Outweigh the Benefits of Inclusion - Spivey Pond 
Management Area (SPMA)

    We believe that the benefits of excluding the entire 54-ac (22-ha) 
SPMA from the designation of critical habitat for the California red-
legged frog outweigh the benefits of including the SPMA in critical 
habitat. We find that including the SPMA would result in very minimal, 
if any, additional benefits to the California red-legged frog as 
explained above. The critical habitat designation would remain on lands 
surrounding the SPMA, thereby providing a measure of protection for the 
PCEs outside the area, while the management plan would protect the PCEs 
and provide additional benefits of nonnative predator control, habitat 
management and creation, and pollution monitoring within the Plan area. 
We have worked cooperatively with the BLM and other agencies and 
assisted in development of the SPMA Plan. We believe that utilizing the 
Secretary's discretion in excluding the portions of this unit managed 
under the SPMA will encourage other willing landowners in the unit to 
continue their conservation activities and allow the Service to

[[Page 12869]]

expand interest of other private landowners in the unit into 
conservation partnerships for conserving additional frog habitat. The 
benefits of exclusion include providing an incentive for continued 
conservation and restoration on private lands where landowners have 
shown a willingness to participate in such activities.

Exclusion Will Not Result in Extinction of the Species - SPMA

    We find that the exclusion of these lands will not lead to the 
extinction of the species, nor hinder its recovery because the 
management emphasis of the SPMA is to protect and enhance habitat for 
the California red-legged frog. The SPMP consists of six management 
objectives specifically designed for the conservation of the California 
red-legged frog. Additionally, the jeopardy standard of section 7 of 
the Act and routine implementation of conservation measures through the 
section 7 process also provide assurances that the species will not go 
extinct as a result of this exclusion. As a result of ongoing 
management and protection of California red-legged frogs and their 
habitat at Spivey Pond through the development and implementation of 
the 2004 Management Plan for the Spivey Pond Management Area, the 
Secretary has determined to exercise his discretion to exclude the 
entire 54 ac (22 ha) of land owned by the Bureau of Land Management 
from Unit ELD-1 at Spivey Pond from critical habitat under section 
4(b)(2) of the Act.
Hearst Ranch Conservation Easement
    The Hearst Ranch Conservation Easement (Easement), held by the 
California Rangeland Trust, encompasses 81,000 ac (33,000 ha) of 
privately owned lands near the town of San Simeon in northern San Luis 
Obispo County of which 34,777 ac (14,074 ha) occur within Unit SLO-2. 
The Easement was signed on February 18, 2005, and the Hearst Ranch San 
Simeon Conservation Easement Management Plan (Plan) was put into place 
on February 17, 2006. The Easement and Plan provide protective measures 
for California red-legged frogs, which occur in several drainages 
within the boundaries of the Easement. The Easement and Plan also 
include: (1) Protective measures for the diverse communities and 
habitats, including wetlands, marshes, riparian areas, grasslands, and 
stock ponds, that collectively constitute California red-legged frog 
habitat; and (2) connectivity both within the boundaries of the 
Easement and connectivity to other open spaces surrounding the 
Easement, which is important for California red-legged frog dispersal. 
The Easement allows for grazing, farming, and development to occur in 
some areas. Future development is limited to an inn at Old San Simeon 
Village, limited employee housing, and a maximum of 27 new owner 
homesites. However, the Plan provides management directives that 
protect California red-legged frogs and their habitat including: 
maintaining cross fencing and livestock water systems to achieve good 
cattle distribution and to keep cattle from damaging riparian areas; 
locating salt blocks at least 0.25 mi (0.4 km) from water sources to 
encourage good cattle distribution and prevent salt from entering 
riparian areas; preventing overgrazing by establishing limits on 
residual dry matter; maintaining a residual dry matter cushion during 
drought conditions by reducing the size of the cattle herd or using a 
supplemental forage mix; selecting homesite locations to avoid impacts 
to conservation values, including California red-legged frogs and their 
habitat; and in farmed areas, mechanically managing weeds, preventing 
all irrigation water from entering flowing water courses and ponds, and 
mandating setbacks to buffer riparian areas from farming operations. 
Monitoring is conducted to ensure that the Plan continually provides 
sufficient protection of the Easement conservation values. Monitoring 
that provides information about the status of California red-legged 
frog habitat includes: annual photo point monitoring of Pico Creek, 
Little Pico Creek, Arroyo Laguna, San Carpoforo Creek, representative 
stock ponds, and representative wetland plant communities; annual 
residual dry matter monitoring; proper stream function evaluations of 
Pico Creek, Little Pico Creek, Arroyo Laguna, Arroyo de la Cruz, and 
San Carpoforo Creek every 5 years; and rangeland and habitat health 
evaluations every 5 years. Monitoring results are summarized and made 
available to the public by the California Rangeland Trust. If drainages 
show impairment
due to the operations of the ranch, corrective actions will be taken 
and may include: deferred grazing; changing the seasonality or length 
of grazing; reducing cattle grazing numbers near stream corridors; 
changing rotational grazing patterns; installing additional riparian 
pasture fencing; installing additional off-stream water troughs; 
placing salt and supplements farther away from impacted areas; removing 
noxious plants within the riparian area; installing additional erosion 
control structures; and/or instituting greater cropland setbacks from 
stream corridors. At least once every 5 years, the property is audited 
by a committee consisting of the Director of the California Rangeland 
Trust, the Executive Director of the Wildlife Conservation Board (a 
board under the California Department of Fish and Game with the 
authority and funding to conduct wildlife conservation programs and 
acquisitions), and a Certified Range Manager, for compliance with the 
Conservation Easement.
    Based on the reasoning below, the Secretary has determined to 
exercise his discretion to exclude approximately 34,777 ac (14,074 ha) 
of land from Unit SLO-2 in San Luis Obispo County under section 4(b)(2) 
of the Act.
Benefits of Inclusion - Hearst Ranch
    One benefit of including an area in a critical habitat designation 
is the requirement of Federal agencies to ensure actions they fund, 
authorize, or carry out are not likely to result in destruction or 
adverse modification of designated critical habitat, which is one of 
the regulatory standards under which consultation is completed. Unlike 
a jeopardy analysis, which looks at an action's impact on survival and 
recovery of the species, an adverse modification analysis looks at the 
action's effects on the designated habitat's contribution to the 
species' conservation. If, through consultation, the Service determines 
that a project may result in adverse modification, the Service will 
suggest reasonable and prudent alternatives that can be taken by the 
Federal agency or applicant to avoid adversely modifying the designated 
critical habitat while implementing the proposed action. Consultations 
that conclude that a proposed action is not likely to result in adverse 
modification may recommend additional conservation measures, but such 
measures would be discretionary on the part of the Federal agency.
    Another benefit of including lands in a critical habitat 
designation is the designation can serve to educate the public 
regarding the potential conservation value of an area, and may help 
focus conservation efforts to designated areas of high conservation 
value for certain species. The process of proposing and finalizing the 
revised critical habitat rule provided the Service with the opportunity 
to evaluate and refine the features essential to the conservation of 
the species within the geographical area occupied by it at the time of 
listing, as well as to evaluate

[[Page 12870]]

whether there are other areas essential for the conservation of the 
species. The designation process included peer review and public 
comment on the identified features and areas. This process is valuable 
to landowners and managers in developing conservation management plans 
for identified areas, as well as any other occupied habitat or suitable 
habitat that may not have been included in the Service's determination 
of essential habitat. However, the educational benefits of designating 
lands within the Hearst Ranch Conservation Easement are small because, 
as discussed above, Hearst Ranch is aware of the value of its lands to 
the conservation of the California red-legged frog, and currently 
implements management measures to conserve California red-legged frogs 
and their habitat. Further, much of Hearst Ranch was included in the 
proposed designation, which itself reached a wide audience. The 
educational benefits that might follow critical habitat designation 
(such as providing information to Hearst Ranch managers on areas 
important to the long-term conservation of this species) were already 
provided by: (1) Developing the Easement and Plan, (2) the original 
designation process in 2001 (66 FR 14626), and (3) publication of the 
revised critical habitat designation in 2006 (71 FR 19244).
    In light of the continued commitment by Hearst Ranch to manage 
their lands in a manner that promotes conservation of the California 
red-legged frog and because monitoring is conducted and reviewed by a 
third party to ensure the Easement and Plan are being complied with, we 
believe designation of Easement lands within Unit SLO-2 as critical 
habitat would provide few, if any, additional regulatory and 
conservation benefits to the species.
Benefits of Exclusion - Hearst Ranch
    The benefits of excluding approximately 34,777 ac (14,074 ha) of 
Hearst Ranch Easement lands are significant. Benefits include relieving 
landowners from any additional regulatory burden that might be imposed 
by a critical habitat designation. The Easement took years to develop 
in cooperation with several State agencies and non-governmental 
organizations, and is consistent with conservation objectives for 
California red-legged frogs. Furthermore, the Easement and Plan provide 
conservation benefits for unlisted sensitive species. Imposing 
additional regulatory review as a result of the designation may 
undermine conservation efforts and partnerships that would otherwise 
benefit the California red-legged frog as well as other species. 
Designation of critical habitat within the boundaries of a conservation 
easement that provides conservation measures for a species could be 
viewed as a disincentive to those entities currently developing these 
plans or contemplating them in the future, because one of the 
incentives for undertaking conservation is greater ease of permitting 
where listed species are affected. Excluding Easement lands will also 
preserve a partnership between the Service and Hearst Ranch, which may 
encourage other conservation partnerships between our two entities in 
the future.
Benefits of Exclusion Outweigh Benefits of Inclusion - Hearst Ranch
    As discussed in the ``Benefits of Inclusion - Hearst Ranch'' 
section above, we believe the regulatory benefit of designating 
critical habitat on lands covered by the Hearst Ranch Conservation 
Easement and Plan would be low. The Easement and Plan address 
conservation issues from a coordinated, integrated perspective rather 
than a piecemeal project-by-project approach and will achieve more 
California red-legged frog conservation than we would achieve through 
multiple site-by-site, project-by-project, section 7 consultations 
involving consideration of critical habitat. We believe the 
conservation benefits for California red-legged frogs that would occur 
as a result of designating those 34,777 ac (14,074 ha) in Unit SLO-2 as 
critical habitat (e.g., protection afforded through the section 7(a)(2) 
consultation process) is minimal compared to the overall conservation 
benefits for the species that will be realized through the Hearst Ranch 
Conservation Easement and Plan.
    Furthermore, the educational benefits of critical habitat 
designation, including informing the public of areas important for the 
long-term conservation of the species, are accomplished from material 
provided on our website and through notices of public comment periods 
associated with the original California red-legged frog critical 
habitat rule (66 FR 14626), the first revised critical habitat rule (71 
FR 19244), and the development of the Easement and Plan. Further, many 
educational benefits of critical habitat designation will be achieved 
through the overall designation, and will occur whether or not this 
particular location is designated. For these reasons, we believe that 
designating critical habitat has little benefit in areas covered by the 
Hearst Ranch Easement and Plan.
    The exclusion of the Hearst Ranch lands from California red-legged 
frog critical habitat will help preserve the partnerships that we 
developed with Hearst Ranch. It may also help encourage new 
partnerships with other landowners and jurisdictions. These 
partnerships are critical for the conservation of California red-legged 
frogs.
    We reviewed and evaluated the exclusion of 34,777 ac (14,074 ha) of 
private lands within the Hearst Ranch Easement area from the final 
revised critical habitat designation for the California red-legged frog 
and determined that the benefits of excluding these lands in Unit SLO-2 
outweigh the benefits of including them. As discussed above, the 
Easement and Plan will provide for preservation and management of 
habitat for and features essential to the conservation of the species.
Exclusion Will Not Result in Extinction of the Species - Hearst Ranch
    We do not believe that this exclusion would result in the 
extinction of the species because the Hearst Ranch Conservation 
Easement and Plan provides for conservation of the species in this area 
through the detailed management practices and monitoring described 
above.
Special Rule Under Section 4(d) of the Act
    In the April 13, 2006, Federal Register (71 FR 19244), we finalized 
a special rule for the California red-legged frog as defined under 
section 4(d) of the Act to ease the general take prohibitions for 
routine ranching activities by non-Federal entities on private and 
tribal lands. Under section 4(d) of the Act, the Secretary may publish 
a special rule that modifies the standard protections for threatened 
species under the Service's regulations implementing section 9 of the 
Act at 50 CFR 17.31 with special measures tailored to the conservation 
of the species that are determined to be necessary and advisable. We 
reviewed the special rule at 50 CFR 17.43(d), and we determined that 
the special rule is appropriate and will remain in place for the 
California red-legged frog. For more information on the ``Special Rule 
Under Section 4(d) for Routine Livestock Ranching Activities'' see the 
April 13, 2006, Federal Register (71 FR 19244).

Required Determinations

Regulatory Planning and Review - Executive Order 12866

    The Office of Management and Budget (OMB) has determined that this 
rule is not significant under E.O. 12866. OMB

[[Page 12871]]

bases its determination upon the following four criteria:
    (1) Whether the rule will have an annual effect of $100 million or 
more on the economy or adversely affect an economic sector, 
productivity, jobs, the environment, or other units of the government.
    (2) Whether the rule will create inconsistencies with other Federal 
agencies' actions.
    (3) Whether the rule will materially affect entitlements, grants, 
user fees, loan programs, or the rights and obligations of their 
recipients.
    (4) Whether the rule raises novel legal or policy issues.

Regulatory Flexibility Act (5 U.S.C. 601 et seq.)

    Under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.), as 
amended by the Small Business Regulatory Enforcement Fairness Act (5 
U.S.C. 802(2)), whenever an agency is required to publish a notice of 
rulemaking for any proposed or final rule, it must prepare and make 
available for public comment a regulatory flexibility analysis that 
describes the effect of the rule on small entities (i.e., small 
businesses, small organizations, and small government jurisdictions). 
However, no regulatory flexibility analysis is required if the head of 
an agency certifies the rule will not have a significant economic 
impact on a substantial number of small entities. The Small Business 
Regulatory Enforcement Fairness Act amended the Regulatory Flexibility 
Act to require Federal agencies to provide a certification statement of 
the factual basis for certifying that the rule will not have a 
significant economic impact on a substantial number of small entities. 
In this final rule, we are certifying that the critical habitat 
designation for the California red-legged frog will not have a 
significant economic impact on a substantial number of small entities. 
The following discussion explains our rationale.
    According to the Small Business Administration, small entities 
include small organizations, such as independent nonprofit 
organizations; small governmental jurisdictions, including school 
boards and city and town governments that serve fewer than 50,000 
residents; and small businesses (13 CFR 121.201). Small businesses 
include manufacturing and mining concerns with fewer than 500 
employees, wholesale trade entities with fewer than 100 employees, 
retail and service businesses with less than $5 million in annual 
sales, general and heavy construction businesses with less than $27.5 
million in annual business, special trade contractors doing less than 
$11.5 million in annual business, and agricultural businesses with 
annual sales less than $750,000. To determine if potential economic 
impacts to these small entities are significant, we considered the 
types of activities that might trigger regulatory impacts under this 
designation as well as types of project modifications that may result. 
In general, the term significant economic impact is meant to apply to a 
typical small business firm's business operations.
    To determine if the revised designation of critical habitat for the 
California red-legged frog would affect a substantial number of small 
entities, we considered the number of small entities affected within 
particular types of economic activities, such as residential and 
commercial development. We apply the ``substantial number'' test 
individually to each industry or category to determine if certification 
is appropriate. In estimating the numbers of small entities potentially 
affected, we also considered whether their activities have any Federal 
involvement; some kinds of activities are unlikely to have any Federal 
involvement and thus will not be affected by the designation of 
critical habitat.
    Designation of critical habitat only affects activities conducted, 
funded, permitted, or authorized by Federal agencies; non-Federal 
activities are not affected by the designation. In areas where the 
species is present, Federal agencies already are required to consult 
with us under section 7 of the Act on activities they fund, permit, or 
implement that may affect the California red-legged frog (see Section 7 
Consultation section). Federal agencies also must consult with us if 
their activities may affect critical habitat. Designation of critical 
habitat, therefore, could result in an additional economic impact on 
small entities due to the requirement to reinitiate consultation for 
ongoing Federal activities (see Application of the ``Adverse 
Modification'' Standard section)
    In the DEA of the proposed revision of critical habitat, we 
evaluated the potential economic effects on small business entities 
resulting from conservation actions related to the proposed revision of 
critical habitat for the California red-legged frog. The analysis is 
based on the estimated incremental impacts associated with the 
rulemaking as described in section 2 of the analysis. In the FEA, we 
evaluated the potential economic effects on small business entities 
resulting from implementation of conservation actions related to the 
proposed revision to critical habitat for the California red-legged 
frog. The economic analysis identifies the estimated incremental 
impacts associated with the proposed rulemaking as described in 
chapters 4 through 12, and evaluates the potential for economic impacts 
related to activity categories including: urban development; water 
management; agricultural crop farming; grazing and ranching; timber 
harvest activities; transportation; utility and oil and gas pipeline 
construction and maintenance and mining activities; fire management 
activities; and habitat and vegetation management activities. The 
analysis concludes that incremental impacts to development and 
agriculture may affect small entities. However, for urban development, 
less than 1 percent (0.04) (19 out of 46,240) of small developers are 
anticipated to be impacted in the next 22 years. Similarly, for 
agriculture, only 1.6 percent (198 out of 12,060) of small farms are 
expected to be affected. Please refer to our final economic analysis of 
critical habitat designation for the California red-legged frog for a 
more detailed discussion of potential economic impacts.
    In summary, we considered whether the final rule to revise critical 
habitat would result in a significant economic impact on a substantial 
number of small entities. For the above reasons and based on currently 
available information, we certify that this rule will not have a 
significant economic impact on a substantial number of small entities. 
Therefore, a regulatory flexibility analysis is not required.

Energy Supply, Distribution, or Use - Executive Order 13211

    E.O. 13211 requires agencies to prepare Statements of Energy 
Effects when undertaking certain actions. This revision to critical 
habitat for the California red-legged frog is not considered a 
significant regulatory action under E.O. 12866. OMB has provided 
guidance for implementing E.O. 13211 that outlines nine outcomes that 
may constitute ``a significant adverse effect'' when compared without 
the regulatory action under consideration. The economic analysis finds 
that none of these criteria are relevant to this designation of 
critical habitat. Thus, based on information in the economic analysis 
(Appendix A), energy-related impacts associated with California red-
legged frog conservation activities within the areas included in this 
final designation of critical habitat are not expected. As such, this 
final designation of revised critical habitat is not expected to 
significantly affect energy supplies, distribution, or use,

[[Page 12872]]

and a Statement of Energy Effects is not required.

Unfunded Mandates Reform Act (2 U.S.C. 1501 et seq.)

    In accordance with the Unfunded Mandates Reform Act, the Service 
makes the following findings:
    (1) This rule will not produce a Federal mandate. In general, a 
Federal mandate is a provision in legislation, statute, or regulation 
that would impose an enforceable duty upon State, local, or tribal 
governments, or the private sector, and includes both ``Federal 
intergovernmental mandates'' and ``Federal private sector mandates.'' 
These terms are defined in 2 U.S.C. 658(5)-(7). ``Federal 
intergovernmental mandate'' includes a regulation that ``would impose 
an enforceable duty upon State, local, or [T]ribal governments'' with 
two exceptions. It excludes ``a condition of Federal assistance.'' It 
also excludes ``a duty arising from participation in a voluntary 
Federal program,'' unless the regulation ``relates to a then-existing 
Federal program under which $500,000,000 or more is provided annually 
to State, local, and [T]ribal governments under entitlement 
authority,'' if the provision would ``increase the stringency of 
conditions of assistance'' or ``place caps upon, or otherwise decrease, 
the Federal Government's responsibility to provide funding,'' and the 
State, local, or Tribal governments ``lack authority'' to adjust 
accordingly. At the time of enactment, these entitlement programs were: 
Medicaid; AFDC work programs; Child Nutrition; Food Stamps; Social 
Services Block Grants; Vocational Rehabilitation State Grants; Foster 
Care, Adoption Assistance, and Independent Living; Family Support 
Welfare Services; and Child Support Enforcement. ``Federal private 
sector mandate'' includes a regulation that ``would impose an 
enforceable duty upon the private sector, except (i) a condition of 
Federal assistance; or (ii) a duty arising from participation in a 
voluntary Federal program.''
    The designation of critical habitat does not impose a legally 
binding duty on non-Federal government entities or private parties. 
Under the Act, the only regulatory effect is that Federal agencies must 
ensure that their actions do not destroy or adversely modify critical 
habitat under section 7. While non-Federal entities who receive Federal 
funding, assistance, permits, or otherwise require approval or 
authorization from a Federal agency for an action, may be indirectly 
impacted by the designation of critical habitat, the legally binding 
duty to avoid destruction or adverse modification of critical habitat 
rests squarely on the Federal agency. Furthermore, to the extent that 
non-Federal entities are indirectly impacted because they receive 
Federal assistance or participate in a voluntary Federal aid program, 
the Unfunded Mandates Reform Act would not apply, nor would critical 
habitat shift the costs of the large entitlement programs listed above 
onto State governments.
    (2) We do not believe that this rule will significantly or uniquely 
affect small governments because it would not produce a Federal mandate 
of $100 million or greater in any year; that is, it is not a 
``significant regulatory action'' under the Unfunded Mandates Reform 
Act. Small governments will be affected only to the extent that any 
programs having Federal funds, permits, or other authorized activities 
must ensure that their actions will not adversely affect the critical 
habitat. Therefore, a Small Government Agency Plan is not required.

Takings--Executive Order 12630

    In accordance with Executive Order (E.O.) 12630 (``Government 
Actions and Interference with Constitutionally Protected Private 
Property Rights''), we have analyzed the potential takings implications 
of designating critical habitat for the California red-legged frog in a 
takings implications assessment. Critical habitat designation does not 
affect landowner actions that do not require Federal funding or 
permits, nor does it preclude development of habitat conservation 
programs or issuance of incidental take permits to permit actions that 
do require Federal funding or permits to go forward. The takings 
implications assessment concludes that this final designation of 
revised critical habitat for California red-legged frog does not pose 
significant takings implications for lands within or affected by the 
designation.

Federalism - Executive Order 13132

    In accordance with E.O. 13132 (Federalism), the final rule does not 
have significant Federalism effects. A Federalism assessment is not 
required. In keeping with Department of the Interior and Department of 
Commerce policy, we requested information from, and coordinated 
development of, this critical habitat designation with appropriate 
State resource agencies in California. During the public comment 
periods, we contacted appropriate State and local agencies and 
jurisdictions, and invited them to comment on the proposed revised 
critical habitat designation for the California red-legged frog. We 
used the comments we received to help us refine this final designation. 
We received one comment letter from the State of California, Military 
Department Office of the Adjutant General (see ``Summary of Comments 
and Recommendations'' section). The designation may have some benefit 
to these governments in that the areas that contain the features 
essential to the conservation of the species are more clearly defined, 
and the primary constituent elements of the habitat essential to the 
conservation of the species are specifically identified. This 
information does not alter where and what federally sponsored 
activities may occur. However, it may assist local governments in long-
range planning (rather than having them wait for case-by-case section 7 
consultations to occur).

Civil Justice Reform - Executive Order 12988

    In accordance with E.O. 12988 (Civil Justice Reform), it has been 
determined that the rule does not unduly burden the judicial system and 
meets the requirements of sections 3(a) and 3(b)(2) of the Order. We 
are revising critical habitat in accordance with the provisions of the 
Act. This final rule uses standard property descriptions and identifies 
the primary constituent elements within the designated areas to assist 
the public in understanding the habitat needs of the California red-
legged frog.

Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.)

    This rule does not contain any new collections of information that 
require approval by OMB under the Paperwork Reduction Act of 1995. This 
rule will not impose recordkeeping or reporting requirements on State 
or local governments, individuals, businesses, or organizations. An 
agency may not conduct or sponsor, and a person is not required to 
respond to, a collection of information unless it displays a currently 
valid OMB control number.

Government-to-Government Relationship with Tribes

    In accordance with the President's memorandum of April 29, 1994, 
Government-to-Government Relations with Native American Tribal 
Governments (59 FR 22951), E.O. 13175, and the Department of the 
Interior's manual at 512 DM 2, we readily acknowledge our 
responsibility to communicate meaningfully with recognized Federal 
tribes on a government-to-government basis. In accordance with 
Secretarial Order 3206

[[Page 12873]]

of June 5, 1997 (American Indian Tribal Rights, Federal-Tribal Trust 
Responsibilities, and the Endangered Species Act), we readily 
acknowledge our responsibilities to work directly with tribes in 
developing programs for healthy ecosystems, to acknowledge that tribal 
lands are not subject to the same controls as Federal public lands, to 
remain sensitive to Indian culture, and to make information available 
to tribes.
    As a result of changing the extent of Unit MEN-1 in Mendocino 
County, the proposed revised critical habitat designation contained 
approximately 92 ac (37 ha) of Tribal land. We contacted the Bureau of 
Indian Affairs and the Manchester Point Arena Band of Pomo Indians 
regarding our proposed revision of critical habitat (Service File 
81420-2009-TA-0751). As of the date of this notice, we have not 
received any concerns from or been contacted by the Bureau of Indian 
Affairs or the Manchester Point Arena Band of Pomo Indians regarding 
the designation of critical habitat on the tribal lands identified in 
Unit MEN-1. Therefore, we have designated the tribal lands within Unit 
MEN-1 as critical habitat for the California red-legged frog.

National Environmental Policy Act (NEPA) (42 U.S.C. 4321 et. seq.)

    It is our position that, outside the jurisdiction of the Circuit 
Court of the United States for the Tenth Circuit, we do not need to 
prepare environmental analyses as defined by NEPA in connection with 
designating critical habitat under the Act. We published a notice 
outlining our reasons for this determination in the Federal Register on 
October 25, 1983 (48 FR 49244). This assertion was upheld by the 
Circuit Court of the United States for the Ninth Circuit (Douglas 
County v. Babbitt, 48 F.3d 1495 (9th Cir. 1995), cert. denied 516 U.S. 
1042 (1996)).

(Rana aurora draytonii)'' to read as follows:


Sec.  17.95  Critical Habitat--Fish and Wildlife.

* * * * *
    (d) Amphibians.
* * * * *
California Red-legged Frog (Rana draytonii)
    (1) Critical habitat units are depicted for Alameda, Butte, 
Calaveras, Contra Costa, El Dorado, Kern, Kings, Los Angeles, Marin, 
Mendocino, Merced, Monterey, Napa, Nevada, Placer, Riverside, San 
Benito, San Joaquin, San Luis Obispo, San Mateo, Santa Barbara, Santa 
Clara, Santa Cruz, Solano, Sonoma, Stanislaus, Ventura, and Yuba 
Counties, California, on the maps below.
    (2) Within these areas, the primary constituent elements for the 
California red-legged frog consist of four components:
    (i) Aquatic Breeding Habitat. Standing bodies of fresh water (with 
salinities less than 4.5 ppt), including natural and manmade (e.g., 
stock) ponds, slow-moving streams or pools within streams, and other 
ephemeral or permanent water bodies that typically become inundated 
during winter rains and hold water for a minimum of 20 weeks in all but 
the driest of years.
    (ii) Aquatic Non-Breeding Habitat. Freshwater pond and stream 
habitats, as described in paragraph (2)(i) of this entry, that may not 
hold water long enough for the species to complete its aquatic life 
cycle but which provide for shelter, foraging, predator avoidance, and 
aquatic dispersal of juvenile and adult California red-legged frogs. 
Other wetland habitats considered to meet these criteria include, but 
are not limited to: plunge pools within intermittent creeks, seeps, 
quiet water refugia within streams during high water flows, and springs 
of sufficient flow to withstand short-term dry periods.
    (iii) Upland Habitat. Upland areas adjacent to or surrounding 
breeding and non-breeding aquatic and riparian habitat up to a distance 
of 1 mi (1.6 km) in most cases (i.e., depending on surrounding 
landscape and dispersal barriers) including various vegetational

[[Page 12874]]

series such as grassland, woodland, forest, wetland, or riparian areas 
that provide shelter, forage, and predator avoidance for the California 
red-legged frog. Upland habitat should include structural features such 
as boulders, rocks and organic debris (e.g., downed trees, logs), small 
mammal burrows, or moist leaf litter. Upland features are also 
essential in that they are needed to maintain the hydrologic, 
geographic, topographic, ecological, and edaphic features that support 
and surround the aquatic, wetland, or riparian habitat. These upland 
features contribute to:
    (A) Filling of aquatic, wetland, or riparian habitats;
    (B) Maintaining suitable periods of pool inundation for larval 
frogs and their food sources; and
    (C) Providing non-breeding, feeding, and sheltering habitat for 
juvenile and adult frogs (e.g., shelter, shade, moisture, cooler 
temperatures, a prey base, foraging opportunities, and areas for 
predator avoidance).
    (iv) Dispersal Habitat. Accessible upland or riparian habitat 
within and between occupied locations within a minimum of 1 mi (1.6 km) 
of each other and that support movement between such sites. Dispersal 
habitat includes various natural habitats, and altered habitats such as 
agricultural fields, that do not contain barriers (e.g., heavily 
traveled roads without bridges or culverts) to dispersal. Dispersal 
habitat does not include moderate- to high-density urban or industrial 
developments with large expanses of asphalt or concrete, nor does it 
include large lakes or reservoirs over 50 ac (20 ha) in size, or other 
areas that do not contain those features identified in paragraphs 
(2)(i), (2)(ii), and (2)(iii) of this entry as essential to the 
conservation of the species.
    (3) Critical habitat does not include manmade structures existing 
on the effective date of this rule and not containing one or more of 
the primary constituent elements, such as buildings, aqueducts, 
airports, and roads, and the land on which such structures are located.
    (4) Critical habitat map units. Data layers defining map units were 
created on a base of USGS 7.5' quadrangles using USDA National 
Agricultural Imagery Program (NAIP) county-wide MrSID compressed 
mosaics of 1 meter resolution and natural color aerial photography from 
summer 2005. Critical habitat units were then mapped using Universal 
Transverse Mercator (UTM) zone 10 and zone 11, North American Datum 
(NAD) 1983 coordinates.
