SUPPLEMENTARY INFORMATION:

Designation of Critical Habitat Provides Little Additional Protection 
to Species

    In 30 years of implementing the Endangered Species Act of 1973, as 
amended (Act) (16 U.S.C. 1531 et seq.), we have found that the 
designation of statutory critical habitat provides little additional 
protection to most listed species, while consuming significant amounts 
of available conservation resources. Our present system for designating 
critical habitat has evolved since its original statutory prescription 
into a process that provides little real conservation benefit, is 
driven by litigation and the courts rather than biology, limits our 
ability to fully evaluate the science involved, consumes enormous 
agency resources, and imposes huge social and economic costs. We 
believe that additional agency discretion would allow our focus to 
return to those actions that provide the greatest benefit to the 
species most in need of protection.

Role of Critical Habitat in Actual Practice of Administering and 
Implementing the Act

    While attention to, and protection of, habitat is paramount to 
successful conservation actions, we have consistently found that, in 
most circumstances, the designation of critical habitat is of little 
additional value for most listed species, yet it consumes large amounts 
of conservation resources. Sidle (1987) stated, ``Because the ESA can 
protect species with and without critical habitat designation, critical 
habitat designation may be redundant to the other consultation 
requirements of section 7.''
    Currently, only 445 species or 36 percent of the 1,244 listed 
species in the U.S. under our jurisdiction have designated critical 
habitat. We address the habitat needs of all 1,244 listed species 
through conservation mechanisms such as listing, section 7 
consultations, the section 4 recovery planning process, the section 9 
protective prohibitions of unauthorized take, section 6 funding to the 
States, and the section 10 incidental take permit process. We believe 
that it is these measures that may make the difference between 
extinction and survival for many species.

Procedural and Resource Difficulties in Designating Critical Habitat

    We have been inundated with lawsuits for our failure to designate 
critical habitat, and we face a growing number of lawsuits challenging 
critical habitat determinations once they are made. These lawsuits have 
subjected us to an ever-increasing series of court orders and court-
approved settlement agreements, compliance with which now consumes 
nearly the entire listing program budget. This leaves us with little 
ability to prioritize our activities to direct scarce listing resources 
to the listing program actions with the most biologically urgent 
species conservation needs.
    The consequence of the critical habitat litigation activity is that 
limited listing funds are used to defend active lawsuits, and to comply 
with the growing number of adverse court orders. As a result, our own 
proposals to list critically imperiled species, and make final listing 
determinations on existing proposals, are all significantly delayed.
    The accelerated schedules of court-ordered designations have left 
us with almost no ability to provide for adequate public participation 
or to ensure a defect-free rulemaking process before making decisions 
on listing and critical habitat proposals due to the risks associated 
with noncompliance with judicially-imposed deadlines. This, in turn, 
fosters a second round of litigation in which those who fear adverse 
impacts from critical habitat designations challenge those 
designations. The cycle of litigation appears endless, is very 
expensive, and in the final analysis, provides relatively little 
additional protection to listed species.

[[Page 23255]]

    The costs resulting from the designation include legal costs, the 
cost of preparation and publication of the designation, the analysis of 
the economic effects, and the cost of requesting and responding to 
public comment, and in some cases the costs of compliance with the 
National Environmental Policy Act of 1969--all are part of the cost of 
critical habitat designation. These costs result in minimal benefit to 
the species that is not already afforded by the protections of the Act 
enumerated earlier, and they directly reduce the funds available for 
direct and tangible conservation actions.

Public Comments Solicited

    We intend that any final action resulting from this proposal will 
be as accurate and as effective as possible. Therefore, comments or 
suggestions from the public, other concerned governmental agencies, the 
scientific community, industry, or any other interested party 
concerning this proposed rule are hereby solicited. Comments 
particularly are sought concerning:

    (1) The reasons why any habitat should or should not be 
determined to be critical habitat as provided by section 4 of the 
Act, including whether the benefit of designation will outweigh any 
threats to the species due to designation;
    (2) Specific information on the amount and distribution of 
arroyo toad habitat, and what habitat is essential to the 
conservation of the species and why;
    (3) Land use designations and current or planned activities in 
the areas proposed as critical habitat and their possible impacts on 
proposed critical habitat;
    (4) Any foreseeable economic or other potential impacts 
resulting from the proposed designation--in particular, any impacts 
on small entities;
    (5) Economic and other values associated with designating 
critical habitat for the arroyo toad, such as those derived from 
nonconsumptive uses (e.g., hiking, camping, bird-watching, enhanced 
watershed protection, improved air quality, increased soil 
retention, ``existence values,'' and reductions in administrative 
costs); and
    (6) Whether our approach to designating critical habitat could 
be improved or modified in any way to provide for greater public 
participation and understanding, or to assist us in accommodating 
public concerns and comments.

    If you wish to comment, you may submit your comments and materials 
concerning this proposal by any one of several methods (see ADDRESSES 
section). Please submit Internet comments to [email protected] in 
ASCII file format and avoid the use of special characters or any form 
of encryption. Please also include ``Attn: Arroyo toad'' in your e-mail 
subject header and your name and return address in the body of your 
message. If you do not receive a confirmation from the system that we 
have received your Internet message, contact us directly by calling our 
Ventura Fish and Wildlife Office at phone number 805/644-1766. Please 
note that the Internet address [email protected] will be closed out 
at the termination of the public comment period.
    Our practice is to make comments, including names and home 
addresses of respondents, available for public review during regular 
business hours. Individual respondents may request that we withhold 
their home address from the rulemaking record, which we will honor to 
the extent allowable by law. There also may be circumstances in which 
we would withhold from the rulemaking record a respondent's identity, 
as allowable by law. If you wish us to withhold your name and/or 
address, you must state this prominently at the beginning of your 
comment. However, we will not consider anonymous comments. We will make 
all submissions from organizations or businesses, and from individuals 
identifying themselves as representatives or officials of organizations 
or businesses, available for public inspection in their entirety. 
Comments and materials received will be available for public 
inspection, by appointment, during normal business hours at the above 
address.

Public Hearings

    The Act provides for one or more public hearings on this proposal, 
if requested. Requests for public hearings must be made, in writing, at 
least 15 days prior to the close of the public comment period. We will 
schedule public hearings on this proposal, if any are requested, and 
announce the dates, times, and places of those hearings in the Federal 
Register and local newspapers at least 15 days prior to the first 
hearing.

Background

    Background information on the arroyo toad can be found in our final 
designation of critical habitat for this species, published on February 
7, 2001 (66 FR 9414). That information is incorporated by reference 
into this proposed rule. The following new information has come to our 
attention since that time:
    (1) Individual toads have been observed as far as 1.2 miles (mi) (2 
kilometers (km)) from the streams where they breed (Service 1999; 
Varanus Biological Services, Inc., in litt. 1999), but are most 
commonly found within 650 to 3,280 feet (ft) (200 to 1,000 meters (m)) 
of those streams in coastal areas with broad floodplains (Griffin et 
al. 1999; Holland and Sisk 2000), and 160 to 650 ft (50 to 200 m) in 
more mountainous areas away from the coast (Ramirez 2002a, 2002b, 
2002c, 2003). Arroyo toads typically burrow underground during periods 
of inactivity and thus tend to use upland habitats that have sandy, 
friable (readily crumbled) soils, but upland sites with extremely 
compact soils can also be used (D. Holland, in litt. 2000).
    (2) Juvenile arroyo toads remain on or near the saturated substrate 
at the edges of breeding pools from a week to several months after 
metamorphosis (D. Holland, in litt. 2000). They are active during the 
day and can be exposed on the barren sand, although they are rather 
cryptic (i.e., hidden or camouflaged) at this time. Crushing of toads 
by humans, livestock, or vehicles can be a substantial source of 
mortality at this stage (Service 1999; D. Holland, in litt. 2000).
    (3) In a study using pitfall traps, Holland and Sisk (2000) 
reported arroyo toad captures in upland habitats averaging more than 
1,640 ft (500 m) and 980 ft (300 m) from two separate coastal streams; 
one arroyo toad was even captured 3,940 ft (1,175 m) beyond the edge of 
the riparian habitat bordering the stream. However, radio telemetry and 
pitfall trap studies from a variety of inland streams often bordered by 
steep, dry terrain show arroyo toad activity typically closer to the 
active stream channel. Four separate studies of inland populations by 
Ramirez (2002a, 2002b, 2002c, 2003) showed that arroyo toads burrowed 
no farther than 121 to 1,062 ft (37 to 324 m) from the edge of a 
stream, with an overall average of approximately 52 ft (16 m) between a 
toad's burrow and the edge of the stream.
    (4) The nonnative organisms whose introduction and spread into 
arroyo toad habitat can pose a particularly serious threat include, 
among others, giant reed (Arundo donax), bullfrogs (Rana catesbeiana), 
green sunfish (Lepomis cyanellus), and chytrid fungus (Batrachochytrium 
dendrobatidis) (Sweet 1992; Service 1999; S. Sweet, pers. comm. 2003).
    (5) In addition to a variety of other human activities outlined in 
a previous Federal Register notice (66 FR 9414), off-highway vehicle 
use within stream channels, floodplains, and adjacent uplands and the 
inadvertent or intentional introduction of nonnative species may cause 
adverse impacts to arroyo toads.

Previous Federal Actions

    We designated a total of approximately 182,360 acres (ac) (73,780 
hectares (ha)) of critical habitat for the arroyo toad on February 7, 
2001 (66 FR 9414). On November 6, 2001, the Building Industry Legal 
Defense Foundation, Foothill/Eastern Transportation Corridor Agency, 
National Association of Home Builders, California Building Industry 
Association, and Building Industry Association of San Diego County 
filed a lawsuit in the District of Columbia against the Service 
challenging the designation of arroyo toad critical habitat and 
alleging errors by the Service in promulgating the final rule. Building 
Industry Legal Defense Foundation, et al. v. Gale Norton, Secretary of 
the Interior, et al. Civ. No. 01-2311 (JDB) (D.D.C.). On October 30, 
2002, the court set aside the designation and ordered us to publish a 
new critical habitat designation final rule for the arroyo toad by July 
30, 2004.
    This proposal for critical habitat differs from the previous 
designation of critical habitat for the arroyo toad with respect to the 
mapping grid size and changes in locations of critical habitat due to 
new survey data. We reduced the minimum mapping unit from a 250-meter 
UTM grid to a 100-meter UTM grid. This allows for the grid to more 
closely follow watershed boundaries. Based on new survey results and 
reevaluation of arroyo toad habitat, additional stream reaches are 
included in this proposal, including sections of the Santa Clara River, 
Cajon Wash, Kitchen Creek, and Kinley Creek. The lengths of several 
streams included in proposed critical habitat are also reduced in 
several instances from the previous designation. These reductions occur 
where the likelihood of arroyo toad occupancy and the quality of arroyo 
toad habitat are low, such as along portions of Piru, San Francisquito, 
and Castaic Creeks. In addition, we have determined that habitat 
conditions in Arroyo Seco are not essential for the conservation of the 
species since closer scrutiny and comments from Forest Service 
biologists and USGS biologists indicate the stream gradient in Arroyo 
Seco is too steep for the arroyo toad. Consequently, we have not 
included this area in this proposal. New exclusions from critical 
habitat under section 4(b)(2) are contained in this proposed rule and 
discussed in the relevant exclusion sections.

Critical Habitat

    Critical habitat is defined in section 3 of the Act. It receives 
protection under section 7 of the Act. Further information regarding 
the definition of critical habitat and how we implement related 
policies and regulations can be found in the Federal Register at 66 FR 
9414.

Methods

    Our methods for identifying the arroyo toad critical habitat 
included in this proposal are identical to the methods we used to make 
our final designation for this species on February 7, 2001 (66 FR 
9414).

Primary Constituent Elements

    In accordance with section 3(5)(A)(i) of the Act and regulations at 
50 CFR 424.12, in determining which areas to designate as critical 
habitat, we consider those physical and biological features (primary 
constituent elements) that are essential to the conservation of the 
species, and that may require special management considerations or 
protection. These features are used for all listed species and include, 
but are not limited to: Space for individual and population growth and 
for normal behavior; food, water, or other nutritional or physiological 
requirements; cover or shelter; sites for breeding, reproduction, and 
rearing of offspring; and habitats that are protected from disturbance 
or are representative of the historic and geographical and ecological 
distributions of a species.
    The specific biological and physical features, otherwise referred 
to as the primary constituent elements (PCEs), which comprise essential 
arroyo toad habitat are described below. These lands provide aquatic 
and terrestrial habitat essential for the maintenance of self-
sustaining populations and metapopulations (a set of local populations 
or breeding sites within an area, where typically migration from one 
local population or breeding site to other areas containing suitable 
habitat is possible, but not routine) of arroyo toads throughout its 
range.

Space for Individual and Population Growth, and for Normal Behavior

    The arroyo toad is found along medium-to-large-sized streams in 
coastal and desert drainages in central and southern California and 
Baja, Mexico. It occupies aquatic, riparian (areas near a source of 
water), and upland habitats in a reduced number of suitable drainages 
within its range. Essential habitat for the arroyo toad is created and 
maintained by the fluctuating hydrological, geological, and ecological 
processes operating in riparian ecosystems and the adjacent uplands. 
Periodic flooding that modifies stream channels, redistributes channel 
sediments, and alters pool location and form, coupled with upper 
terrace stabilization by vegetation, is required to keep a stream 
segment suitable for all life stages of the arroyo toad. Periodic 
flooding helps maintain areas of open, sparsely vegetated, sandy stream 
channels and terraces.
    Eggs and tadpoles require aquatic habitat, as described below. 
Juvenile and adult arroyo toads require and spend much of their lives 
in riparian and upland habitats adjacent to breeding locations. 
Riparian habitats used by subadults and adults for foraging and 
burrowing include sand bars, alluvial terraces, and streamside benches 
that lack vegetation, or are sparsely to moderately vegetated. Upland 
habitats used by arroyo toads during both the breeding and nonbreeding 
seasons include alluvial scrub, coastal sage scrub, chaparral (shrubby 
plants adapted to dry summers and moist winters), grassland, and oak 
woodland. Arroyo toads also have been found in agricultural fields 
(Griffin et al. 1999), but these lands may constitute sinks (areas 
where mortality rates are higher than reproduction rates) over the long 
term, due to tilling, pesticide and fertilizer applications, and heavy 
equipment use (Griffin and Case 2001).
    The substrate in habitats preferred by arroyo toads consists 
primarily of sand, fine gravel, or pliable soil, with varying amounts 
of large gravel, cobble, and boulders. Areas that are damp and have 
less than 10 percent vegetation cover provide the best conditions for 
juvenile survival and rapid growth (Service 1999). Arroyo toads must be 
able to move between the stream and upland foraging sites, as well as 
up and down the stream corridor.

Food, Water, and Physiological Requirements

    Arroyo toad tadpoles eat microscopic algae, bacteria, and 
protozoans sucked up from the spaces among pebbles, gravel, and sand or 
abraded from stones (Sweet 1992). Juveniles and adults feed on insects, 
but specialize on ants. When foraging, arroyo toads are often found 
around the driplines of oak trees. These areas often lack vegetation, 
yet have sufficient levels of prey. When active at night, toads often 
can be observed near ant trails feeding on ants, beetles, and other 
prey.

Cover or Shelter

    During the day and other periods of inactivity, arroyo toads seek 
shelter by burrowing into the sand. Thus, areas of sandy or friable 
(readily crumbled) soils are necessary to burrow, but these soils can 
be interspersed with gravel or

[[Page 23257]]

cobble deposits. Arroyo toads may also seek temporary shelter under 
rocks or debris and have been found in mammal burrows on occasion. 
Upland sites with extremely compact soils can also be used for foraging 
and dispersal (D. Holland, in litt. 2000).

Sites for Breeding, Reproduction and Rearing of Offspring

    The arroyo toad has specialized breeding habitat requirements. They 
favor shallow pools and open sand and gravel channels along low-
gradient (typically less than 6 percent) reaches of medium-to-large-
sized streams (Service 1999). These streams can have either 
intermittent or perennial streamflow and typically experience periodic 
flooding that scours vegetation and replenishes fine sediments. In at 
least some portions of its range, the species also breeds in smaller 
streams and canyons where low-gradient breeding sites are more 
sporadically distributed. Breeding pools must persist long enough for 
the completion of larval development (at least in most years), which is 
generally March through June, depending on location and weather. Sweet 
(1992) measured the average age to metamorphosis of arroyo toad larvae 
on the Los Padres National Forest at 71 days, with a predicted minimum 
of 62 days. Peak metamorphosis occurs during June and July in the 
northern part of the toad's range, and from late April through June 
further south, although it may be later, particularly at higher 
elevations (D. Holland, in litt. 2000).
    Breeding arroyo toads lay their eggs in water over substrates of 
sand, gravel, or cobble in open sites such as overflow pools, old flood 
channels, and shallow pools along streams. Such habitats rarely have 
closed canopies over the lower banks of the stream channel due to 
periodic flood events. Heavily shaded pools are generally unsuitable 
for larval and juvenile arroyo toads because of lower water and soil 
temperatures and poor algal mat development. Pools less than 12 inches 
(30 centimeters (cm)) deep with clear water, flow rates less than 0.2 
ft per second (5 cm per second), and bottoms composed of sand or well-
sorted fine gravel are favored by adults for breeding and egg 
deposition (Sweet 1992). Larvae usually hatch in 4 to 6 days at water 
temperatures of 54 to 59 degrees Fahrenheit (12 to 16 degrees Celsius). 
Although egg strings are laid in very slow moving water, larvae 
(tadpoles) can be found in water velocities of up to 1.0 to 1.3 ft per 
second (30 to 40 cm per second) (Sweet 1992).

Disturbance, Protection, and the Historical Geographical Distributions

    As a result of agriculture and urbanization, and the construction, 
operation, and maintenance of water storage reservoirs, flood control 
structures, roads, and recreational facilities such as campgrounds and 
off-highway vehicle parks, many arroyo toad populations have been 
reduced in size or extirpated (eliminated) due to extensive habitat 
loss from the 1920s into the 1990s. Although these factors have not 
dramatically reduced the range of the arroyo toad, within its range 
many of the habitats that were historically capable of supporting large 
numbers of arroyo toads have been lost in the last 100 years. Jennings 
and Hayes (1994) believe that the loss of habitat, coupled with the 
manipulation of water levels in many central and southern California 
streams and rivers, predation from introduced aquatic species, and 
habitat degradation from introduced plant species, caused arroyo toads 
to be extirpated from 76 percent of their previously occupied habitat 
in California. Through focused survey efforts over the past few years, 
a few new arroyo toad populations have been discovered. Because of 
these recent efforts, however, it is unlikely that many more 
populations remain undiscovered. The conservation and subsequent 
protection of the remaining arroyo toad populations are essential for 
its conservation (Service 1999).
    Pursuant to our regulations, we are required to identify the known 
physical and biological features, i.e., PCEs, essential to the 
conservation of the arroyo toad, together with a description of any 
critical habitat that is proposed. In identifying the PCEs, we used the 
best available scientific and commercial data available. The physical 
ranges described in the PCEs may not capture all of the variability 
that is inherent in natural systems that support arroyo toads. The PCEs 
determined essential to the conservation of arroyo toad include, but 
are not limited to:
    1. Rivers or streams with hydrologic regimes that supply water to 
provide space, food, and cover needed to sustain eggs, tadpoles, 
metamorphosing juveniles, and adult breeding toads. Specifically, the 
conditions necessary to allow for successful reproduction of arroyo 
toads are:
    a. breeding pools with areas less than 12 in (30 cm) deep;
    b. areas of flowing water with current velocities less than 1.3 ft 
per second (40 cm per second); and
    c. surface water that lasts for a minimum length of 2 months in 
most years, i.e., a sufficient wet period in the spring months to allow 
arroyo toad larvae to hatch, mature, and metamorphose.
    2. Low-gradient stream segments (typically less than 6 percent) 
with sandy or fine gravel substrates that support the formation of 
shallow pools and sparsely vegetated sand and gravel bars for breeding 
and rearing of tadpoles and juveniles.
    3. A natural flooding regime, or one sufficiently corresponding to 
a natural regime, that will periodically scour riparian vegetation, 
rework stream channels and terraces, and redistribute sands and 
sediments, such that breeding pools and terrace habitats with scattered 
vegetation are maintained.
    4. Riparian and adjacent upland habitats (particularly alluvial 
streamside terraces and adjacent valley bottomlands that include areas 
of loose soil where toads can burrow underground) to provide foraging 
and living areas for subadult and adult arroyo toads.
    5. Stream channels and adjacent upland habitats that allow for 
migration to foraging areas, overwintering sites, dispersal between 
populations, and recolonization of areas that contain suitable habitat.
    Arroyo toads are not distributed uniformly throughout the critical 
habitat units. Arroyo toad breeding habitat is patchily distributed 
along the stream courses, and the same is true of appropriate upland 
habitat. Some areas primarily provide for migration and dispersal 
between breeding and foraging habitats or allow for dispersal to 
additional breeding pools that will accommodate increased populations 
during favorable years. Habitat conditions within streams can change 
rapidly in response to streamflows and other factors, such as the 
development and shifting of sand and gravel bars, and creation and 
disappearance of pools. Terrace and upland habitats, although more 
stable than streambed and riparian habitats, may change as a result of 
rainfall, earthquakes, fires, and other natural events. These factors 
may cause the habitat suitability of given areas to vary over time, 
thus affecting the distribution of arroyo toads.
    The combination of appropriate aquatic, riparian, and upland 
habitats forms ecologically functional units. These features and the 
lands that they represent are essential to the conservation of the 
arroyo toad. All lands identified as essential and proposed as critical 
habitat contain one or more of the PCEs for the arroyo toad.

[[Page 23258]]

Criteria Used To Identify Critical Habitat

    The criteria we used to identify critical habitat are identical to 
the criteria outlined in the final designation previously published in 
the Federal Register on February 7, 2001 (66 FR 9414).
    To evaluate our critical habitat model, we assessed its 
effectiveness at capturing documented toad locations from studies that 
focused specifically on surveying toads in upland habitats and studies 
involving radio telemetry. Holland and Sisk (2000) established 
extensive pitfall trap arrays at discrete distances from two stream 
courses and operated these arrays at various periods throughout the 
year. They had 466 captures of arroyo toads, 35 (7.5 percent) of which 
were identified as being in upland areas. Those toads were captured at 
distances that ranged from 49 to 3,855 ft (15 to 1,175 m) from the 
upland-riparian ecotone (boundary) (Holland and Sisk 2000). For the two 
areas sampled in that study (Cristianitos Creek and the upper Santa 
Margarita River), we found that our critical habitat boundaries 
encompassed an average of 76 percent of the pitfall trapping stations 
where arroyo toads were detected.
    We also assessed studies that involved the tracking of arroyo toads 
with radio telemetry equipment. For example, in a number of studies by 
Ramirez (2002a, 2002b, 2002c, 2003), arroyo toads were tracked from the 
end of breeding activity until the commencement of aestivation, 
generally May through September. Cumulatively, these four studies 
involved the tracking of 77 adult arroyo toads in three separate 
critical habitat units in Orange, San Bernardino, and Los Angeles 
Counties. All but one of the numerous burrow sites chosen by these 
arroyo toads fell within our proposed critical habitat boundaries.

Proposed Critical Habitat Designation

    The approximate area encompassing the proposed critical habitat by

    Critical habitat includes arroyo toad habitat throughout the 
species' range in the United States (i.e., Monterey, Santa Barbara, 
Ventura, Los Angeles, Riverside, San Bernardino, Orange, and San Diego 
Counties, CA). Lands proposed for critical habitat designation are 
under private, local agency, county, State, Tribal, and Federal 
ownership, and have been divided into 23 Critical Habitat Units. 
Although all of the units we are proposing for critical habitat are 
within the geographic range of the species, we are not proposing all of 
the areas known to be occupied by the arroyo toad. We are not proposing 
any areas outside of the geographical area occupied by the species at 
the time it was listed. A brief description of each unit, and reasons 
why it is essential for the conservation of the arroyo toad, are 
presented below. The units are generally based on geographically 
distinct river basins. In several instances, a river basin has been 
broken into two or more units based on human or natural landscape 
features that effectively separate portions of the basin (e.g., a large 
reservoir or gorge). Based on observations recorded since 1985, each 
unit is occupied by arroyo toads.
    Jennings and Hayes (1994) estimate that arroyo toads have lost 76 
percent of their historic habitat. Although the linear measure of 
historically occupied streams may not be 4 times what is currently 
occupied, museum records and data on extant populations indicate that 
the habitats capable of supporting large numbers of arroyo toads have 
decreased dramatically in the last 100 years. The reaches that 
typically support, or historically supported, the highest densities of 
toads are those in the lower and middle portions of river basins, 
usually associated with third order (a stream characterization based on 
size) or larger streams. Many of those reaches have been lost to, or 
degraded by, urban development, intensive agriculture, water 
diversions, sand and gravel mining operations, and reservoirs. As 
discussed in more detail below, with respect to the individual units, 
we find that all of the areas we are proposing for designation may 
require special management considerations or protections due to threats 
to the species and/or its habitat. Such management considerations and 
protections would benefit the arroyo toad and its habit because: Exotic 
predators and pets may eat or injure arroyo toads; unnatural water 
releases from dams can wash away arroyo toad eggs and tadpoles, promote 
the growth of exotic species, or reduce the availability of open sand 
bar habitat; water diversions can dry a streambed prior to the 
completion of metamorphosis from tadpole to toad; toads can be crushed 
by channel maintenance, road construction, or the plowing of 
agricultural fields with heavy machinery; toads can be trampled during 
recreational activities; arroyo toad habitat can be adversely affected 
by agricultural practices, the invasion of exotic species, inundation 
from water impoundments, or frequent human use; and water quality can 
be compromised by runoff from urban, industrial, or agricultural land 
uses. However, the designation of critical habitat does not carry with 
it any requirement that landowners or land managers implement any 
special management or protection programs.

Northern Region

    The following seven critical habitat units are located in the 
Northern Region for the arroyo toad, as discussed in the Recovery Plan 
(Service 1999). Most of the lands are federally owned, and special 
management considerations and protections for the toad will likely be 
addressed through the section 7 consultation process and the 
development of management plans and conservation strategies. Because 
the toad populations in this unit have been reduced in size, and their 
habitat fragmented by road construction, dams, agriculture, and 
urbanization, it is essential to protect them to reduce further loss of 
genetic diversity and safeguard against the loss of any one population 
due to random natural or human-caused events. The Forest Service is the 
primary landowner of proposed critical habitat within the Northern 
Region. However, a very small proportion of Forest Service land in this 
region falls within critical habitat proposed for the arroyo toad.

Unit 1: San Antonio River, Monterey County

    Unit 1 consists of the San Antonio River and adjacent uplands, from 
about 2 mi (3 km) upstream of the confluence with Mission Creek 
downstream to San Antonio Reservoir, a distance of about 17 mi (27 km), 
and includes small portions of Mission Creek and other tributaries. The 
unit encompasses approximately 6,546 ac (2,649 ha), of which more than 
98 percent is on the Fort Hunter Liggett Military Reservation and the 
other 2 percent is privately owned.
    The northernmost known population of arroyo toads is located here, 
and is approximately 100 mi (160 km) north of the nearest documented 
extant population. The onset of breeding activity along the San Antonio 
River has not been documented prior to the last week in April (Liz 
Clark, U.S. Army Reserve, pers. comm. 2003), which is several weeks 
later than the onset of breeding activity documented for arroyo toad 
populations on the Los Padres National Forest to the south (Sweet 
1992). Arroyo toads in this unit may experience climatic conditions not 
faced by toads at sites found farther south. The protection of this 
area is essential to maintaining the complete genetic variability of 
the species and the full range of ecological settings within which it 
is found, which is essential to the ability of the arroyo toad to adapt 
to changing environmental conditions. Arroyo toads can be found along 
the entire length of this segment of the San Antonio River (Service 
1999), which is still in a relatively natural state, consists of high-
quality arroyo toad habitat, and supports probably one of the largest 
populations within the Northern Region. This area contains all the 
primary constituent elements, including breeding pools in low-gradient 
stream segments, sandy substrates, seasonal flood flows, and relatively 
undisturbed riparian habitat and upland benches for foraging and 
dispersal.
    We consider other areas along the San Antonio River within Fort 
Hunter Liggett as essential for the conservation of the species, but 
excluded them from this proposal because they are within

[[Page 23260]]

mission-essential training areas (see Exclusions Under Section 
4(b)(2)). Thus, we are proposing the majority of the essential lands 
along the San Antonio River as critical habitat, but we are excluding a 
portion of the essential lands (less than 50 percent), which are within 
mission-essential training areas on Fort Hunter Liggett (Army 2003). 
Military operations (including occasional troop movements and weed 
control) in and near the riparian zone, yet outside of mapped mission-
essential training areas, may create the need for special management 
considerations in this unit.

Unit 2: Sisquoc River, Santa Barbara County

    Unit 2 consists of 27 mi (43 km) of the Sisquoc River and adjacent 
uplands, from Sycamore Campground downstream to just below the 
confluence with La Brea Creek. The unit encompasses approximately 6,574 
ac (2,660 ha), of which 61 percent is private land and 39 percent is 
within the Los Padres National Forest. Upper stretches of the river are 
within the National Forest and mostly within the San Rafael Wilderness 
Area. Below the National Forest boundary, the river and adjacent 
uplands are on rural private lands. This long, undammed stream is 
occupied arroyo toad habitat and is one of the few remaining major 
rivers in southern California with a natural flow regime. This area 
contains all of the primary constituent elements, including breeding 
pools in low-gradient stream segments, sandy or fine gravel substrates, 
seasonal flood flows, and relatively undisturbed riparian/upland 
habitat for foraging and dispersal. This area is essential to 
maintaining genetic diversity of the species. The protection of this 
population is essential as it is a core population. Grazing, sand and 
gravel mining, and limited recreational activities are the primary 
disturbances to arroyo toad habitat in this unit that may require 
special management considerations.

Unit 3: Upper Santa Ynez River Basin, Santa Barbara County

    Unit 3 is located upstream of Gibraltar Reservoir and incorporates 
portions of the upper Santa Ynez River, Indian Creek, Mono Creek, and 
adjacent uplands. The unit encompasses approximately 4,414 ac (1,786 
ha) within the boundaries of Los Padres National Forest, with 88 
percent on National Forest lands and 12 percent on private non-
residential inholdings. The segment of the upper Santa Ynez River 
proposed for designation extends 10 mi (16 km) from Jameson Reservoir 
downstream to Gibraltar Reservoir. Indian Creek is proposed from the 
Buckthorn Creek confluence down to its confluence with Mono Creek, a 
distance of approximately 5 mi (8 km). Mono Creek and associated 
uplands are proposed for designation for 7.5 mi (12 km) from the first 
unnamed stream below The Narrows to its confluence with the Santa Ynez 
River. This area contains all of the primary constituent elements, 
including breeding pools in low-gradient stream segments, sandy or fine 
gravel substrates, seasonal flood flows, and relatively undisturbed 
riparian/upland habitat for foraging and dispersal.
    A large and well-studied arroyo toad population occurs in this area 
(Sweet 1992, 1993). It is likely a remnant of a much larger population 
that historically extended downstream below what is now Lake Cachuma 
and upstream into the area occupied by Jameson Reservoir. The 
population along Mono Creek is one of the more robust populations of 
arroyo toads on the Los Padres National Forest and is free of exotic 
vertebrate predators for much of its length (Jamie Uyehara, Forest 
Service, pers. comm. 2003). Unit 3 is also the wettest area occupied by 
arroyo toads in the Northern Region (Teale Data Center 1998; California 
Irrigation Management Information System 2000).
    Arroyo toads in this unit likely experience precipitation and soil 
moisture conditions not faced by toads at drier sites. Potential 
adaptations to these conditions make the protection of this area 
essential to maintaining the genetic diversity of the species. Because 
it is within, or is surrounded by, National Forest land, this area has 
favorable habitat conditions for population persistence. The arroyo 
toad population inhabiting Mono and Indian Creeks is particularly 
healthy and could be used as a source for the reestablishment of arroyo 
toads in downstream reaches of the Santa Ynez River, if warranted. The 
leading threats to arroyo toads in this area, primarily along the lower 
Santa Ynez River and lower Mono Creek, are from exotic species, 
recreation, and problems associated with an upstream dam (e.g., 
sediment trapping, altered hydrological regime, temperature changes). 
To ensure arroyo toad habitat in this unit is protected, special 
management considerations or protections may be needed.

Unit 4: Sespe Creek, Ventura County

    Unit 4 includes 22 mi (35 km) of Sespe Creek and adjacent uplands, 
from the lower end of Sespe Gorge (elevation approximately 3,530 ft 
(1,076 m)) downstream to the confluence with Alder Creek. The unit 
encompasses approximately 4,138 ac (1,675 ha), of which 87 percent is 
on the Los Padres National Forest, primarily within the Sespe 
Wilderness. The remainder is in remote, private inholdings. One of the 
largest arroyo toad populations on the Los Padres National Forest 
occurs in this unit along Sespe Creek (Forest Service, in litt. 1999), 
which is undammed and retains its natural flooding regime. This core 
population is spread over large areas of excellent habitat, including 
numerous high-quality breeding pools, an abundance of sandy substrates, 
unimpeded seasonal flood flows, and relatively undisturbed riparian 
habitat and upland benches for foraging and dispersal (Service 1999). 
Up to several hundred adult arroyo toads inhabit this reach of the 
Sespe River (Sweet 1992, 1993), and during years of successful 
reproduction, such as 2003, thousands of juveniles can be found as well 
(Tom Murphy, Forest Service, pers. comm. 2003).
    Arroyo toads have been found up to 3,300 ft (1,000 m) in elevation 
in this area, which is one of the highest known occurrences in the 
Northern Region. The arroyo toads in this unit likely experience 
temperature extremes or other environmental conditions not faced by 
toads at lower elevations. Potential adaptations to these conditions 
make the protection of this area essential for the maintenance of the 
genetic diversity of the species. In all likelihood, arroyo toad 
populations in units 4, 5, and 6 historically were part of a large 
Santa Clara River Basin metapopulation. Ecologically, these units 
provided a link between the more coastal populations on the Sisquoc and 
Santa Ynez Rivers, and populations in the Desert Region. Substantial 
barriers to toad movement now exist between these units, including 
dams, agriculture, and urban development. Impacts to the Sespe Creek 
habitat come from recreational activities and exotic predators. Special 
management considerations or protection may be needed to control and 
reverse these threats.

Unit 5: Piru Creek, Ventura and Los Angeles Counties

    Unit 5 includes Piru Creek and adjacent uplands from the confluence 
with Lockwood Creek downstream to Pyramid Reservoir (Subunit 5a), and 
from the confluence with Fish Creek downstream to Lake Piru (Subunit 
5b). Subunit 5b also includes Agua Blanca Creek from Devil's Gateway 
downstream to the confluence with Piru Creek. The unit encompasses 
approximately 3,966

[[Page 23261]]

ac (1,605 ha), 85 percent of which is within the Los Padres and Angeles 
National Forests, with the remaining on a few private inholdings. 
Subunit 5a is in a remote setting within the Los Padres National 
Forest, and most of subunit 5b is within the Sespe Wilderness.
    Although much of the historical arroyo toad habitat along Piru 
Creek is now inundated by the two reservoirs, a substantial arroyo toad 
population occurs in this unit (Service 1999). The upper portion of 
subunit 5a is free of exotic vertebrate predators and the arroyo toad 
population there has been increasing and expanding over the past 
several years (J. Uyehara, pers. comm. 2003). The expansion of the 
population is likely due, in part, to seasonal campground closures and 
the elimination of suction-dredge mining. Because lower Piru Creek 
(subunit 5b) is below a large dam, the habitat there has experienced 
some degradation over the years from perennial water releases, rapid 
changes in flow volume, excessive flows during the breeding season, and 
an increased presence of exotic predators. However, future releases 
from Pyramid Dam are scheduled to more closely mimic natural flows and 
benefit the arroyo toad (Eva Begley, California State Division of Water 
Resources, pers. comm. 2003). This should result in an expanded, stable 
population distributed over areas of good-to-excellent habitat that is 
generally undisturbed by human activities. Both upper and lower Piru 
Creek contain all of the primary constituent elements, including 
breeding pools in low-gradient stream segments, sandy substrate, 
seasonal flood flows (modified to some extent below Pyramid Dam), and 
riparian habitat and upland benches for foraging and dispersal. Special 
management considerations may be required above and beyond those 
currently in place to address threats posed by horse and cattle 
grazing, recreation, and unnatural flows that could potentially be 
released from Pyramid Dam.

Unit 6: Upper Santa Clara River Basin, Los Angeles County

    Unit 6 includes portions the Santa Clara River, Castaic Creek, San 
Francisquito Creek, and adjacent uplands. The unit encompasses 
approximately 7,398 ac (2,994 ha) of which 83 percent is private land 
and 17 percent is within the Angeles National Forest. Subunit 6a, 
predominantly within the Angeles National Forest, includes Castaic 
Creek from Bear Canyon downstream to Castaic Lake, and Fish Creek from 
Cienaga Spring to the confluence with Castaic Creek. Subunit 6b 
includes Castaic Creek from the downstream edge of The Old Road right-
of-way (adjacent to Interstate 5) down to the confluence with the Santa 
Clara River, the Santa Clara River from the confluence with Bouquet 
Creek down to the confluence with Castaic Creek, and San Francisquito 
Creek from Drinkwater Canyon downstream to the confluence with the 
Santa Clara River. Subunit 6c includes the upper Santa Clara River from 
Arrastre Canyon downstream to the confluence with Bee Canyon Creek.
    A healthy population of arroyo toads can be found on Castaic Creek 
above the reservoir (subunit 6a) (Bill Brown, Forest Service, pers. 
comm. 2003). Although unknown at the time the Recovery Plan was 
published (Service 1999), arroyo toads also occupy subunit 6b along the 
Santa Clara River. This portion of the Santa Clara River was originally 
excluded from designation as critical habitat for the arroyo toad, in 
part because we believed that a breeding population of arroyo toads 
could not be sustained in this area. Recent observations of arroyo 
toads, including eggs, prove this to be incorrect (Ruben Ramirez, Cadre 
Environmental, pers. comm. 2003). We had also previously stated (66 FR 
9414) that the Natural River Management Plan (NRMP) (Valencia Company 
1998) adequately protected this section of the Santa Clara River as a 
dispersal corridor. However, uplands along this section of the Santa 
Clara River remain unprotected and threatened by development. Because 
this section of the Santa Clara River supports a breeding population of 
arroyo toads, connects arroyo toad habitat in Castaic Creek with San 
Francisquito Creek, and is in need of further protection, we believe it 
is essential habitat for the arroyo toad metapopulation in the upper 
Santa Clara River Basin and, in turn, is essential for the conservation 
of the species.
    Although not detected during a recent survey (Impact Sciences 
2001), the Castaic Creek portion of subunit 6b contains high-quality 
arroyo toad habitat within its meandering floodplain and is connected 
to the occupied reach of the Santa Clara River. The habitat in this 
river segment is important to the long-term persistence of the Santa 
Clara River population by allowing for natural population expansion and 
fluctuation. Although previously included as critical habitat for the 
arroyo toad, the portion of Castaic Creek from The Old Road Bridge 
(adjacent to Interstate 5) upstream to Castaic Lagoon contains largely 
marginal to moderate quality habitat and is not included in this 
proposal. Arroyo toads have not been detected in this reach during 
recent surveys (Impact Sciences 2001). Although the habitat looks 
suitable for arroyo toads, they have not been detected during recent 
surveys in San Francisquito Creek, which empties into the Santa Clara 
River (Ed Ervin, U.S. Geological Survey (USGS), pers. comm. 2003). 
However, in 1997, calling arroyo toad males were heard along San 
Francisquito Creek near the old St. Francis Dam (Ian Swift, Mountains 
Recreation and Conservation Authority, pers. comm. 2003). In any event, 
lower San Francisquito Creek offers an excellent opportunity for 
further expansion of the arroyo toad population in subunit 6b and is 
important for the long-term persistence of the Santa Clara River 
population. The upper portion of the Santa Clara River (subunit 6c) 
supports a breeding population of arroyo toads (N. Sandburg, in litt. 
2001; Rick Farris, Service, pers. comm. 2001; Frank Hovore, Hovore and 
Associates, in litt. 2001) and has the potential to greatly increase in 
size with appropriate protection.
    Subunits 6a, 6b, and 6c contain all the primary constituent 
elements, including breeding pools in low-gradient stream segments, 
sandy substrates, seasonal flood flows, and riparian and upland 
habitats for foraging and dispersal. The majority of the lands within 
unit 6 are private, and arroyo toad habitat is adversely affected by 
urban development, agriculture, recreation, and mining. Exotic species 
are a concern here as well. Special management considerations or 
protection may be required in this unit to address these threats. This 
unit is the easternmost population in the Northern Region, and as such, 
provides the final link in the range of ecological settings for this 
region the maintenance of which is essential to the conservation of the 
species.

Unit 7: Upper Los Angeles River Basin, Los Angeles County

    Unit 7 includes portions of Big Tujunga, Mill, and Alder Creeks, 
and adjacent uplands in the upper Los Angeles River Basin. The unit 
encompasses approximately 4,213 ac (1,705 ha), of which 64 percent is 
within the Angeles National Forest and 36 percent is on private lands. 
This unit is divided into two subunits. Subunit 7a includes 11.8 mi (19 
km) of Big Tujunga Creek from below Big Tujunga Dam downstream to 
Hansen Lake. Subunit 7b encompasses: (1) Approximately 8 mi (13 km) of 
upper Big Tujunga Creek from immediately above Big Tujunga Reservoir 
upstream to 1.2 mi (2 km)

[[Page 23262]]

above the confluence with Alder Creek, (2) almost 3.7 mi (6 km) of Mill 
Creek from the Monte Cristo Creek confluence downstream to Big Tujunga 
Creek, and (3) 1.9 mi (3 km) of Alder Creek from the Mule Fork 
confluence downstream to Big Tujunga Creek.
    Within the last 15 years, the drainages in this unit have been 
reported to be occupied by arroyo toads (Forest Service, in litt. 1996; 
Forest Service 2000; California Natural Diversity Data Base (CNDDB) 
2003), and, collectively, these toads represent the only significant 
known population remaining in the coastal foothills of the San Gabriel 
Mountains. This unit is essential because it is occupied and contains 
several primary constituent elements including sandy low-gradient 
stream segments and highly braided river channels supporting sparse 
vegetation indicating periodic scouring (USGS 2002). Threats that may 
require special management considerations include adverse (i.e., 
timing, amount) water releases from Big Tujunga Dam, exotic predators, 
such as crayfish and bullfrogs, and exotic plants, such as Arundo 
donax. This unit also contains populations that occur in high-elevation 
environments that are atypical for arroyo toad and that belong to a 
metapopulation of the species in the Northern Region.

Southern Region

    The following 13 critical habitat units are located in the Southern 
Region for the arroyo toad and consist of a range of geographic 
locations from coastal regions to interior mountains. Arroyo toads 
probably occurred throughout the up- and downstream portions of each of 
these rivers and creek basins, but are now found only in segments of 
the rivers and creeks, due to loss or change of habitat and exotic 
predators. Each of these critical habitat units contains river basins 
that are identified in the Southern Region of the Recovery Plan 
(Service 1999). Conserving arroyo toad populations in these river 
basins is necessary for preserving the species' full range of genetic 
and phenotypic variation and is essential to the conservation of the 
species and may require special management considerations or 
protection.

Unit 8: Lower Santa Ana River Basin/Black Star and Baker Creeks, Orange 
County

    Unit 8 includes portions of Black Star and Baker Creeks and 
adjacent uplands in the lower Santa Ana River Basin. The unit 
encompasses approximately 172 ac (70 ha) just above Irvine Lake, of 
which 92 percent is private land and 8 percent is within the Cleveland 
National Forest. We are proposing a 0.7 mi (1 km) stretch of Black Star 
Creek and associated uplands and a 1.5-mi (0.9-km) stretch of lower 
Baker Canyon and associated uplands upstream from the Cleveland 
National Forest boundary as critical habitat. We consider other high-
quality habitats along Santiago Creek as essential but excluded them 
from this proposed rule because they are within the approved Orange 
County Central Coastal Subregion Natural Community Conservation Plan 
(NCCP)/Habitat Conservation Plan (HCP) area (see Discussion in 
Application of Section 4(a)(3)(B) and Exclusions Under Section 
4(b)(2)).
    Unit 8 is considered essential because it contains several primary 
constituent elements including shallow, exposed pools and open habitat 
with sandy terraces (Harmsworth Associates 2001), low-gradient stream 
segments with sandy washes, a natural flooding regime that periodically 
scours riparian vegetation and reworks stream channels and terraces, 
and riparian and adjacent uplands habitats that provide for foraging 
habitat and living areas for adult and subadult toads and dispersal 
between areas containing suitable habitat. Maintaining a population in 
this unit would enhance the viability of the larger arroyo toad 
metapopulation that extends across the lower coastal mountain slopes of 
the Santa Ana Mountains from Santiago Creek to San Mateo Creek 
(crossing into Units 10 and 11). Toads in this unit are significant to 
the overall conservation of the species because they are likely a 
relict population of a larger historical population that existed along 
the lower Santa Ana River Basin prior to the urbanization of the 
greater Los Angeles area. This relict population may contain unique 
genetic variation from a greater Santa Ana River Basin population that, 
with adequate protection and intermittent gene flow, would promote 
greater genetic diversity within the metapopulation. Toads were 
observed in lower Baker Canyon and at the confluence of Silverado Creek 
and Santiago Creek during the 1970s and 1980s (Robert Fisher, USGS, in 
litt. 1985; CNDDB 2003). However, surveys performed along Santiago 
Creek in 1997 failed to detect arroyo toads (Harmsworth Associates 
1998), and reportedly no arroyo toads were detected in 2000 during 
surveys on Irvine Company land within this unit (Harmsworth Associates 
2001). These survey efforts, however, did not cover all of the high-
quality habitats that still exist within this unit (e.g., upper reaches 
of Baker Canyon). Additional surveys are needed to determine the 
occupancy status of toads in this unit and their population size. Since 
suitable habitat still exists, special management considerations, such 
as augmenting or reestablishing toad populations, may be required for 
this unit. Threats that may require special management considerations 
include residential activities near the streams and past commercial 
sand and gravel removal operations.

Unit 9: San Jacinto River Basin / Bautista Creek, Riverside County

    Unit 9 includes portions of Bautista Creek and adjacent uplands in 
the San Jacinto River Basin. The unit encompasses approximately 683 ac 
(276 ha), of which 98 percent is within the San Bernardino National 
Forest and the remaining 2 percent is on State land. We are proposing a 
3.1-mi (5.1-km) discontinuous stretch of Bautista Creek as critical 
habitat. We also consider high-quality habitat along the San Jacinto 
River as essential from the Sand Canyon confluence downstream to the 
Soboba Indian Reservation border and along Bautista Creek from the San 
Bernardino National Forest boundary downstream to near the middle of 
section 27 (T5S, R1E), where the stream enters a debris basin, but 
excluded that area from the proposed critical habitat because it is 
within the Western Riverside MSHCP planning area (see Discussion in 
Application of Section 4(a)(3)(B) and Exclusions Under Section 
4(b)(2)). There is also high-quality habitat on the Soboba Indian 
Reservation along the San Jacinto River and Indian Creek, as well as 
records of arroyo toads upstream from the Reservation along the San 
Jacinto River. However, there is uncertainty regarding the amount of 
high-quality habitat and its occupancy by arroyo toads on the 
Reservation, and therefore, whether this habitat is essential to the 
conservation of the species. As a consequence, we have not included 
lands within the Soboda Indian Reservation in the proposed rule. We are 
interested in working with the Soboba Indian Tribe in determining the 
occupancy of these areas and in developing a management plan that will 
address the conservation needs of the arroyo toad.
    Unit 9 is comprised of a substantial arroyo toad population in 
Bautista Creek within the San Bernardino National Forest (USGS 2000, 
2001). This population, along with another smaller population on the 
San Jacinto River (Brock Ortega, Dudek and Associates, in litt. 2001) 
which is being excluded from proposed critical habitat due to the

[[Page 23263]]

Western Riverside MSHCP, likely extends downstream onto Tribal and 
other private lands, and represents one of the easternmost populations 
within the species' range. Unit 9 is essential for arroyo toad 
conservation because it contains several primary constituent elements 
including low gradient sandy streambeds with slow moving water suitable 
for arroyo toad breeding and adjacent upland terrace for foraging and 
burrowing. The arroyo toad population in this unit is one of the 
easternmost populations and is isolated from other known populations to 
the south in the Santa Margarita Watershed, to the west in the San Juan 
Watershed, and from populations to the north in the Santa Ana 
Watershed. Therefore, conserving this population is important for the 
species' recovery because it may contain unique genetic, phenotypic 
and/or behavioral characteristics. The threats that may require special 
management considerations for this unit include destruction of habitat 
and mortality of individual toads from recreation and vehicular traffic 
from nearby roadways (USGS 2001).

Unit 10: San Juan Creek Basin, Orange County

    Unit 10 includes portions of San Juan Creek, Bell Canyon, Trabuco 
Creek, and adjacent uplands in the San Juan Creek Basin. The unit 
encompasses approximately 6,285 ac (2,544 ha), of which 54 percent is 
private land, 34 percent is Orange County Park Land (Caspers Wilderness 
Park and O'Neill Regional Park), and 12 percent is within the Cleveland 
National Forest. Subunit 10a covers approximately 20.5 mi (33 km) of 
San Juan Creek from the bottom of Decker Canyon downstream to 
Interstate 5 and includes about 2.5 mi (4 km) of Bell Canyon from just 
below Crow Canyon downstream to the confluence with San Juan Creek. 
Subunit 10b covers approximately 5 mi (8 km) of Trabuco Creek from 
Falls Canyon to approximately 0.9 mi (1.4 km) downstream of the State 
Route 241 (Foothill Transportation Corridor) bridge.
    Unit 10 supports a large core population in San Juan and Bell 
Creeks (P. Bloom, environmental consultant, in litt. 1998; USGS, in 
litt. 1999a; CNDDB 2003) that is concentrated within Caspers Wilderness 
Park and private lands downstream (P. Bloom in litt. 1998), the 
protection of which is essential for the conservation of the species. 
These areas contain several primary constituent elements, such as low-
gradient stream segments with sandy or fine gravel substrates that 
support shallow pools and alluvial scrub habitat that provides foraging 
habitat. This unit also supports a population along a stretch of 
Trabuco Creek (D. Holland, in litt. 2000) where conditions such as low-
gradient streams with shallow pools and adjacent upland habitat for 
foraging and burrowing are favorable for population persistence. Arroyo 
toad populations in this unit possibly belong to a greater arroyo toad 
metapopulation in the Santa Ana Mountains and may serve as an important 
linkage between toads in Santiago Creek (Unit 8) to the north and the 
San Mateo Creek Basin to the south. Threats to this population that may 
require special management considerations include exotic predators 
(bullfrogs), increased water diversions, and residual effects of recent 
gravel mining operations (Bloom 1998).

Unit 11: San Mateo Creek Basin, San Diego and Orange Counties

    Unit 11 includes portions of San Mateo, Cristianitos, Talega, 
Gabino, and La Paz Creeks, and adjacent uplands in the San Mateo Creek 
Basin. The unit encompasses approximately 4,580 ac (1,854 ha), of which 
68 percent is within portions of Marine Corps Base, Camp Pendleton 
(Camp Pendleton), including areas leased to outside parties for other 
land uses (i.e., San Onofre State Park and agricultural lands) and 
adjacent cantonment areas; 1 percent is within the Cleveland National 
Forest; and 31 percent is on private land. This unit is divided into 
three subunits. Subunit 11a extends about 3.1 mi (5 km) from the 
Cristianitos Creek confluence downstream to just below Interstate 5. 
Subunit 11a also includes portions of Cristianitos Creek from just 
above Gabino Creek downstream to the confluence with San Mateo Creek. 
This subunit also includes approximately 3.1 mi (5 km) of Gabino Creek 
upstream from its confluence with Cristianitos Creek, including about 
0.6 mi (1 km) of La Paz Creek, as well as approximately 2.7 mi (4.3 km) 
of Talega Creek upstream from its confluence with Cristianitos Creek 
and beyond the boundaries of Camp Pendleton. Subunit 11b covers 
approximately 0.4 mi (0.7 km) of San Mateo Creek beyond the boundaries 
of Camp Pendleton within the Cleveland National Forest near Devils 
Canyon, and subunit 11c covers approximately 3.9 mi (6.3 km) on San 
Onofre Creek within cantonment areas in Camp Pendleton. We consider 
other high-quality habitats along San Mateo, San Onofre, and Talega 
Creeks within Camp Pendleton as essential, but excluded them from this 
proposed rule because they are within mission-essential training areas 
(see Discussion of Exclusions Under Section 4(b)(2)).
    This unit contains several primary constituent elements, including 
low-gradient stream segments with sandy or fine gravel substrates, 
shallow pools for breeding and rearing of tadpoles and juveniles, and 
riparian and adjacent uplands habitats for foraging and dispersal to 
other populations. With so many favorable habitat conditions, Unit 11 
is able to support large core populations in San Mateo and Cristianitos 
Creeks (Holland and Goodman 1998; CNDDB 2003) and is essential for the 
species. An unusual and important aspect of this unit is its close 
proximity to the coast because nearly all of the historic near-coastal 
populations have been extirpated due to extensive urbanization and 
river channelization along the coastal regions of southern California. 
Distinctive climatic conditions near the coast may provide different 
selective pressures on toads in this area, and favor specific genetic 
characteristics that help maintain the genetic diversity of the 
species. Threats to this arroyo toad essential habitat that may require 
special management considerations include cumulative impacts from 
military and other human activities, including direct mortality from 
vehicle collisions and vehicular crossings of stream beds, fire, exotic 
predators, and invasive plants (Holland and Goodman 1998).

Unit 12: Lower Santa Margarita River Basin, San Diego County

    Unit 12 includes approximately 8.7 mi (14 km) of the Santa 
Margarita River and adjacent uplands, including almost 2.1 mi (3.4 km) 
of De Luz Creek from the town of De Luz to the boundary of Camp 
Pendleton (Subunit 12a) in the lower Santa Margarita River Basin, and 
from the lower end of Temecula Canyon along the lower Santa Margarita 
River to the westernmost boundary between Camp Pendleton and the Naval 
Weapons Station Seal Beach Detachment Fallbrook (Fallbrook Naval 
Weapons Station) (Subunit 12b). The unit encompasses approximately 
1,840 ac (745 ha), of which 17 percent is within the Fallbrook Naval 
Weapons Station, 1 percent is on State land, and 82 percent is on 
private land. We consider other high-quality habitats along the Santa 
Margarita River in the very northeastern corner of Camp Pendleton as 
well as further downstream from the Camp Pendleton/Fallbrook boundary 
as essential, but excluded them from this proposed rule because they 
are within mission-essential training areas on Camp

[[Page 23264]]

Pendleton (see Discussion of Exclusions Under Section 4(b)(2)).
    Recent surveys of the Santa Margarita River and De Luz Creek 
immediately downstream of this unit on Camp Pendleton have documented 
what is probably the largest known population of arroyo toads (Holland 
1995; Holland and Goodman 1998; Varanus Biological Services, Inc. 1999; 
Holland and Sisk 2001; CNDDB 2003). This unit contains several primary 
constituent elements including rivers with suitable hydrologic regimes, 
low-gradient stream segments with sandy substrates supporting shallow 
pools and gravel bars for breeding and rearing tadpoles and juveniles, 
and riparian and adjacent upland habitat to provide foraging and living 
areas for subadult and adult toads. This unit is important for the 
recovery of the species because of its size, proximity to other large 
populations on Camp Pendleton, and potential connectivity to 
populations in the upper Santa Margarita River Basin (Unit 13). Threats 
to this habitat that may require special management considerations 
include cumulative impacts to the species' habitat from military and 
other human activities, including direct mortality from vehicle 
collisions and vehicular crossings of stream beds, fire, exotic 
predators, and invasive plants (Holland and Goodman 1998).

Unit 13: Upper Santa Margarita River Basin, San Diego and Riverside 
Counties

    Unit 13 is located upstream from Vail Lake and includes portions of 
Temecula and Arroyo Seco Creeks, and adjacent uplands in the upper 
Santa Margarita Basin. The unit encompasses approximately 3,627 ac 
(1,468 ha), of which 82 percent is private land, 17 percent is within 
the Cleveland National Forest, and 1 percent is BLM land. This unit is 
divided into two subunits. Subunit 13a includes 3.7 mi (5.9 km) of 
Arroyo Seco Creek from Crosley Homestead downstream to just north of 
the Riverside/San Diego County boundary and further downstream within 
the Cleveland National Forest. Subunit 13b includes approximately 7.2 
mi (11.6 km) of Temecula Creek from Dodge Valley downstream to the 
Riverside/San Diego County boundary. We consider other high-quality 
habitats along Temecula, Wilson, and Arroyo Seco Creeks as essential, 
but excluded them from this proposed rule because they are within the 
Western Riverside MSHCP planning area (see Discussion in Application of 
Section 4(a)(3)(B) and Exclusions Under 4(b)(2)).
    Unit 13 contains documented occurrences in Temecula, Wilson, and 
Arroyo Seco Creeks (AMEC Earth and Environmental, Inc. 2001; CNDDB 
2003) and is essential because it contains high-quality habitat, such 
as broad, flat alluvial valleys with good foraging habitat, loose soils 
for burrowing, and shallow pools for breeding. The habitat conditions 
are favorable for population expansion and long-term persistence, and 
the unit provides a potential link to populations in the lower Santa 
Margarita River Basin (Unit 12). Sand mining operations and exotic 
predators (CNDDB 2003) threaten arroyo toad habitat in this unit and 
may require special management considerations.

Unit 14: Lower and Middle San Luis Rey River Basin, San Diego County

    Unit 14 includes portions of the San Luis Rey River below Lake 
Henshaw and adjacent uplands, and includes sections of Pala and Keys 
Creeks in the lower and middle San Luis Rey River Basin. The unit 
encompasses approximately 15,376 ac (6,222 ha), of which 82 percent is 
private land, 12 percent (1856 ac (751 ha)) is on the Pala Indian 
Reservation, and 7 percent (1021 ac (413 ha)) is on the Rincon Indian 
Reservation. Approximately 30 mi (48 km) of the San Luis Rey River from 
the western edge of the La Jolla Indian Reservation downstream to the 
confluence with Guajome Creek near the City of Oceanside are proposed 
for designation. It also includes approximately 3.4 mi (5.5 km) of Pala 
Creek and 1.7 mi (2.7 km) of Keys Creek upstream from their confluence 
with the San Luis Rey River.
    This long, low-elevation (all below 1,000 ft (305 m) in elevation) 
unit is situated in a broad, flat valley with a low-gradient river that 
supports shallow pools and sandy substrates in adjacent upland terraces 
for foraging and burrowing. This unit is essential for the recovery of 
the arroyo toad because it supports one of the largest core populations 
within the species' range (Dudek and Associates, Inc. in litt. 1995; 
Tierra Madre Consultants, Inc., in litt. 1995; California Department of 
Transportation (Caltrans) 1998; Varanus Biological Services, Inc., in 
litt. 1999; KEA Environmental, Inc., in litt. 2000). Special management 
considerations that are required in this unit include minimizing 
impacts from intensive urbanization, agriculture, exotic predators, and 
plants, and addressing issues regarding dams and water diversions in 
the upper end of the unit.
    We are including lands on the Pala and Rincon Indian Reservations 
because they consist of some of the highest quality occupied habitat, 
such as low-gradient rivers containing shallow pools for breeding and 
upland habitat for foraging, in this unit (Tierra Environmental 
Services 1999; Varanus Biological Services, Inc. 1999). If these high-
quality habitats on the Reservations are lost, the migration of 
individuals and continuity of gene flow along the San Luis Rey River 
would be precluded, resulting in fragmentation of remaining toad 
populations outside of the Reservations and their greater 
susceptibility to extirpation. The Service will be attempting to work 
closely with the Pala and Rincon Band of Mission Indians prior to the 
final designation of critical habitat to achieve necessary conservation 
measures for the species and to subsequently exclude the these 
Reservation lands from critical habitat. Designation of these 
Reservation lands is essential to the conservation of the species and 
may require special management considerations, such as minimizing 
development impacts in riparian areas and adjacent upland habitat.

Unit 15: Upper San Luis Rey River Basin, San Diego County

    Unit 15 includes the upper San Luis Rey River above Lake Henshaw, 
two of its headwater tributaries, and adjacent uplands in the upper San 
Luis Rey River Basin. The unit encompasses approximately 11,725 ac 
(4,745 ha), of which 86 percent is private land and 14 percent is 
within the Cleveland National Forest. This unit consists of two 
subunits. Subunit 14a covers almost 8.7 mi (14 km) of the upper San 
Luis Rey River from the Indian Flats area downstream to the upper end 
of Lake Henshaw and includes about 7.8 mi (12.5 km) of Agua Caliente 
Creek from the western edge of section 13 (T10S, R3E) to the confluence 
with the San Luis Rey. Subunit 14b includes approximately 1.6 mi (2.5 
km) of the West Fork of the San Luis Rey River, where it runs through 
Barker Valley. Arroyo toads occur in each of these drainages, with the 
largest concentration found along Agua Caliente Creek.
    This unit is essential because it contains several primary 
constituent elements including low-gradient stream segments with sandy 
substrates supporting shallow pools, and riparian and adjacent upland 
habitats to provide areas foraging and burrowing. This unit is 
important for the recovery of the species because it contains a unique 
assemblage of several small, disjunct, high-elevation arroyo toad 
populations and one large, core population on Agua Caliente Creek (E. 
Gergus, San Diego State University, in litt. 1992; CNDDB 2003) in an 
area where in-stream and/or overland dispersal between

[[Page 23265]]

populations is likely still possible. Maintaining adequate genetic 
connectivity within this population increases the probability of these 
populations' long term persistence. Groundwater pumping on private 
lands, exotic predators, and grazing are the primary disturbances to 
arroyo toad habitat that may require special management in this unit.

Unit 16: Santa Ysabel Creek Basin, San Diego County

    Unit 16 includes portions of Santa Ysabel Creek and adjacent 
uplands, and includes portions of Santa Maria Creek, Guejito Creek, and 
Temescal Creek (Pamo Valley) in the San Dieguito River/Santa Ysabel 
Creek Basin. The unit encompasses approximately 11,080 ac (4,484 ha), 
of which 93 percent is private land, 6 percent is within the Cleveland 
National Forest, and 1 percent is on the Mesa Grande Indian 
Reservation. The unit consists of four subunits. Subunit 16a includes 
approximately 7.9 mi (12.7 km) of Santa Ysabel Creek and adjacent 
uplands from the Mesa Grande Indian Reservation downstream to the 
western boundary of the Cleveland National Forest near Boden Canyon 
(which is the eastern boundary of the San Diego MSCP area). This 
subunit also includes approximately 4.3 mi (7 km) of Temescal Creek 
from the northern edge of Pamo Valley to the confluence with Santa 
Ysabel Creek and 0.1 mi (0.1 km) of Boden Canyon and adjacent uplands 
on the Cleveland National Forest at approximately 0.75 mi (1.2 km) 
upstream from the Santa Ysabel Creek confluence. Subunit 16b includes 
approximately 7.5 mi (12 km) of Guejito Creek from the 2,000-ft (610-m) 
elevation contour downstream to the San Diego MSCP boundary near San 
Pasqual Valley. Subunit 16c covers approximately 5.3 mi (8.5 km) of 
Santa Maria Creek from the west side of Ramona to the San Diego MSCP 
boundary near San Pasqual Valley. Subunit 16d includes approximately 
5.2 mi (8.3 km) of Santa Ysabel Creek and adjacent uplands from 
approximately 0.5 mi (0.8 km) east of Highway 79 downstream to 
approximately 0.25 mi (0.4 km) downstream of the confluence with Witch 
Creek. We consider other high-quality habitats along Santa Ysabel, 
Santa Maria, and Guejito Creeks as essential, but excluded them from 
this proposed rule because they are within the approved San Diego MSCP 
plan area (see discussion in Application of Section 4(a)(3)(B) and 
Exclusions Under Section 4(b)(2) of the Act).
    All of the drainages included in this unit are occupied by arroyo 
toads, and a large population exists along Temescal and Santa Ysabel 
Creeks within Pamo Valley (Varanus Biological Services, Inc. 1999; 
Tierra Environmental Services, in litt. 2001; USGS, in litt. 2002; 
CNDDB 2003). This unit is essential because it contains several primary 
constituent elements including low-gradient sandy stream segments with 
shallow pools for breeding and rearing of tadpoles, and upland sandy 
terraces that provide foraging and burrowing habitat. This unit is also 
essential for the species' recovery because it supports a large core 
population and contains several additional populations that are 
interconnected. In addition, this unit provides an important linkage 
for genetic interchange with a core arroyo toad population in the San 
Pasqual Valley, which is within the San Diego MSCP. A population of 
arroyo toads was recently discovered in high-quality habitat along 
Santa Ysabel Creek upstream from Lake Sutherland (USGS, in litt. 2002). 
Protection of this population, on the Santa Ysabel Open Space Preserve, 
and another population in Witch Creek (E. Gergus, in litt. 1992), a 
tributary of Santa Ysabel Creek, is essential for the recovery of the 
species because they exist in an undammed portion of the Santa Ysabel 
Creek drainage above Lake Sutherland and are thus subject to a more 
natural flooding regime. Within this portion of the upper Santa Ysabel 
Creek, approximately 40 ac (16 ha) of Mesa Grande Indian Reservation is 
included as critical habitat. This Reservation is located between 
occupied areas on the Santa Ysabel Open Space Preserve and the 
confluence of Witch and Santa Ysabel Creeks, which is downstream from 
where toads were discovered in Witch Creek in the early 1990s. 
Conserving habitat on the Mesa Grande Reservation is essential to allow 
for the migration of toads to support the genetic and demographic 
continuity within this population along the upper portions of Santa 
Ysabel Creek. Grazing, exotic predators, and urbanization (Tierra 
Environmental Services, in litt. 2001; CNDDB 2003) are the primary 
threats to this arroyo toad essential habitat that may require special 
management considerations in this unit.

Unit 17: San Diego River Basin/San Vicente Creek, San Diego County

    Unit 17 includes portions of the San Diego River and San Vicente 
Creek and adjacent uplands in the San Diego River Basin. The unit 
encompasses approximately 2,309 ac (934 ha), of which 75 percent is 
private land, 19 percent is within the Cleveland National Forest, and 6 
percent is on the Capitan Grande Indian Reservation. The unit is broken 
into four subunits--three disjunct sections of the San Diego River and 
one section of San Vicente Creek. Subunit 17a includes approximately 5 
mi (8 km) of the San Diego River from Ritchie Creek downstream through 
0.5 mi (0.9 km) of the Capitan Grande Indian Reservation to the upper 
edge of El Capitan Reservoir and approximately 0.6 mi (1 km) of lower 
Cedar Creek. Subunit 17b includes 0.9 mi (1.5 km) of the San Diego 
River from El Capitan Reservoir to El Monte County Park. Subunit 17c 
covers almost 4.3 mi (7 km) of the San Diego River from approximately 
1.2 mi (2 km) below El Monte County Park downstream to the confluence 
with San Vicente Creek. Subunit 17d includes 1.4 mi (2.3 km) of San 
Vicente Creek from the west side of San Diego Country Estates 
downstream to where the creek crosses Wildcat Canyon Road (the MSCP 
area boundary). We consider other high-quality habitats along San 
Vicente Creek and the San Diego River as essential, but excluded them 
from this proposed rule because they are within the approved San Diego 
MSCP plan area (see Discussion in Application of Section 4(a)(3)(B) and 
Exclusions Under Section 4(b)(2)).
    The upper San Diego River and San Vicente Creek are both occupied 
by arroyo toads (E. Gergus, in litt. 1992; Varanus Biological Services, 
Inc. 1999; CNDDB 2003). This unit is essential since it contains 
several primary constituent elements such as low-gradient stream 
segments with sandy substrates supporting shallow pools for breeding, 
riparian and adjacent upland habitats that provide foraging, living, 
and migration areas for subadult and adult toads. This unit is 
important for arroyo toad conservation because it encompasses several 
significant populations and includes suitable habitat for population 
expansion, thus increasing the probability of the long-term persistence 
of these populations. It also provides an important linkage to 
populations occurring within the San Diego MSCP area. This unit also 
includes high quality habitat, such as low-gradient stream segments and 
adjacent upland terrace areas for foraging and burrowing, on the 
Capitan Grande Indian Reservation along the upper portions of the San 
Diego River and above Capitan Reservoir. These areas are between areas 
of occupied high quality habitat outside of the Reservation along the 
San Diego River. Conserving habitat on the Capitan Grande Reservation 
is essential to allow for the migration of toads to support the

[[Page 23266]]

genetic and demographic continuity within this population on the upper 
portions of the San Diego River. Minimizing threats from development is 
necessary to maintain the viability of the populations in this unit. 
Consequently, special management considerations or protection may be 
required.

Unit 18: Sweetwater River Basin, San Diego County

    Unit 18 includes portions of the Sweetwater River, Peterson Canyon, 
Viejas Creek, and adjacent uplands in the Sweetwater River Basin. The 
unit encompasses approximately 9,235 ac (3,737 ha), of which 54 percent 
is private land, 23 percent is on California State Park land, 12 
percent is within the Cleveland National Forest, 8 percent is on the 
San Diego National Wildlife Refuge, 3 percent is on California 
Department of Fish and Game (CDFG) land, and less than 1 percent is on 
the Sycuan Indian Reservation. The unit is broken into four subunits--
three disjunct sections of the Sweetwater River and one section of 
Viejas Creek. Subunit 18a covers approximately 20 mi (32 km) of the 
Sweetwater River from the top of Upper Green Valley in Cuyamaca Rancho 
State Park downstream to the San Diego MSCP area boundary. Subunit 18b 
includes approximately 0.7 mi (1.2 km) of the Sweetwater River between 
the MSCP boundary and Loveland Reservoir and 1.5 mi (2.4 km) of 
Peterson Canyon from just east of the Taylor Creek confluence 
downstream to the top of Loveland Reservoir. Subunit 18c encompasses 
approximately 16 mi (26 km) of the Sweetwater River, within the MSCP 
boundary, from immediately below Loveland Dam downstream to the upper 
edge of Sweetwater Reservoir. Subunit 18d covers 1.8 mi (2.9 km) of 
Viejas Creek and associated uplands from the western border of the 
Viejas Indian Reservation downstream to the Congressional boundary of 
the Cleveland National Forest (also the eastern boundary of the San 
Diego MSCP area). We consider other high-quality habitats along Viejas 
Creek and the Sweetwater River as essential, but excluded these lands 
from the proposed rule because they are within the approved San Diego 
MSCP plan area (see Discussion in Application of Section 4(a)(3)(B) and 
Exclusions Under Section 4(b)(2)).
    The unit is essential to arroyo toad conservation because it 
consists of several primary constituent elements including open sandy 
river bottoms with shallow pools that support breeding populations and 
adjacent upland foraging and burrowing areas. This unit is also 
essential for the species conservation because it supports several 
significant populations over large stretches of rivers and streams (E. 
Gergus, in litt. 1992; Ervin and Griffin, in litt. 1997; Varanus 
Biological Services, Inc. 1999; CNDDB 2003). Maintaining suitable 
habitat conditions and connectivity are essential to provide for the 
long-term persistence of these populations. This unit also includes 
high quality habitat, such as low-gradient stream segments and adjacent 
upland terrace areas for foraging and burrowing, on the Sycuan Indian 
Reservation in the Sweetwater River. This area is between areas of 
occupied high quality habitat outside the Reservation along the 
Sweetwater River. Consequently, conserving habitat on the Sycuan 
Reservation is essential to allow for the migration of toads to support 
the genetic and demographic continuity within the population on this 
portion of the Sweetwater River. This unit may require special 
management considerations to address threats from adverse (i.e., 
timing, amount) water releases from reservoirs, cattle grazing, gravel 
mining operations, off highway vehicular traffic, and exotic predators.

Unit 19: Cottonwood Creek Basin, San Diego County

    Unit 19 includes portions of Cottonwood Creek, adjacent uplands, 
and portions of the following tributaries: Potrero Creek, Pine Valley 
Creek, Scove Canyon, Morena Creek, La Posta Creek, and Kitchen Creek of 
the Cottonwood Creek Basin. This large unit encompasses approximately 
15,798 ac (6,393 ha), of which 55 percent is private land, 37 percent 
is within the Cleveland National Forest, 7 percent is on land owned by 
San Diego County, and 1 percent is on BLM land. The unit consists of 
four disjunct subunits--two sections of Cottonwood Creek and two 
sections of Pine Valley Creek. Subunit 19a covers 7 mi (11.2 km) of 
Cottonwood Creek from Buckman Springs (near Interstate 8) downstream to 
Morena Reservoir and includes approximately 3.7 mi (6 km) of La Posta 
Creek, 2.8 mi (4.5 km) of Morena Creek, and 5 mi (8 km) of Kitchen 
Creek upstream from the Cottonwood Creek confluence. Subunit 19b covers 
almost 9.9 mi (16 km) of Cottonwood Creek from approximately 2.5 mi (4 
km) below Morena Reservoir downstream to State Highway 94 (excluding 
Barrett Reservoir) and includes 9.3 mi (15 km) of Potrero Creek from 
approximately the 2,466-ft (752-m) elevation benchmark downstream to 
the confluence with Cottonwood Creek. Subunit 19c covers about 7.5 mi 
(12 km) of Pine Valley Creek from the north edge of section 12 (T15S, 
R4E) downstream to approximately 0.6 mi (1 km) south of Interstate 8 
and includes approximately 2.5 mi (4 km) of Scove Canyon and 0.6 mi (1 
km) of Noble Creek. Subunit 19d encompasses 8 mi (13 km) of Pine Valley 
Creek from the Nelson Canyon confluence downstream to Barrett 
Reservoir. We consider other high-quality habitats along Cottonwood 
Creek as essential, but excluded them from this proposed rule because 
they are within the San Diego MSCP area (see Discussion in Application 
of Section 4(a)(3)(B) and Exclusions Under Section 4(b)(2)).
    This unit encompasses a large number of distinct arroyo toad 
occurrences (E. Gergus, in litt. 1992; Varanus Biological Services, 
Inc. 1999; USGS, in litt. 1999b; CNDDB 2003) in an area where in-stream 
and/or overland dispersal between populations is probably still 
possible and where there is room for population expansion. It also 
provides an important linkage to populations occurring within the San 
Diego MSCP area. The unit is essential because it includes several 
primary constituent elements including wide, open sandy low-gradient 
stream segments supporting shallow pools for breeding and sparsely 
vegetated upland habitat for foraging and burrowing. Urbanization, 
grazing, Border Patrol activities, introduced plants, and exotic 
predators are the primary threats to this arroyo toad essential habitat 
that may require special management considerations.

Unit 20: Upper Santa Ana River Basin/Cajon Wash, San Bernardino County

    Unit 20 includes approximately 4.8 mi (7.7 km) of Cajon Wash and 
adjacent uplands, from just south of Cajon campground downstream to the 
San Bernardino National Forest boundary. The unit encompasses 
approximately 1,262 ac (511 ha), of which 52 percent is private land 
and 48 percent is within the San Bernardino National Forest.
    This population may represent some of the last vestiges of a much 
greater population that historically existed along the upper Santa Ana 
River Basin, but was almost entirely extirpated due to urbanization of 
the greater Los Angeles area. Arroyo toads were located near the 
junction between Lone Pine Canyon and Cajon Wash in 2000 (USGS 2000). 
The nearest known arroyo toad population occurs approximately 3.7 mi (6 
km) (straight line distance) to the east in the West Fork Mojave River 
(Unit 22). However, the steep terrain between these populations makes 
it likely that

[[Page 23267]]

these populations are isolated from one another. Protecting this 
population is important for the conservation of the species because it 
helps preserve an important outlier segment of the genetic, 
phenotyopic, and/or behavioral variation of the species. This unit is 
essential because it contains several primary constituent elements 
including low-gradient sandy stream segments supporting shallow 
breeding pools, adjacent upland terraces for foraging and burrowing, 
and a flooding regime that sufficiently corresponds to natural 
conditions and periodically scours riparian vegetation and reworks 
stream channels. Recreational usage is the primary threat to this 
habitat that may require special management considerations.
Desert Region
    Arroyo toad populations in the following three critical habitat 
units are essential for the conservation of the species in the Desert 
Region, as described in the Recovery Plan (Service 1999). Each of these 
units is isolated from each other and from any other units, making the 
issues of inbreeding, fragmentation, and random negative impacts of 
great concern. However, this unit also represents unique ecological 
conditions for arroyo toads, and likely harbors important genetic 
diversity.

Unit 21: Little Rock Creek Basin, Los Angeles County

    Unit 21 includes approximately 5.9 mi (9.5 km) of Little Rock Creek 
and adjacent uplands, from the South Fork confluence downstream to the 
upper end of Little Rock Reservoir (in the vicinity of Rocky Point 
Picnic Ground), and approximately 1.1 mi (1.8 km) of Santiago Creek and 
adjacent uplands upstream from the confluence with Little Rock Creek in 
the Little Rock Creek Basin. The unit encompasses approximately 941 ac 
(381 ha), all of which is within the Angeles National Forest.
    Unit 21 is essential for arroyo toad conservation because it 
supports several primary constituent elements including low-gradient 
sandy stream segments that support shallow breeding pools, adjacent 
upland areas for foraging, and a hydrologic regime that sufficiently 
corresponds to natural conditions and scours the riparian vegetation, 
thus providing open areas for movement. This unit is important for the 
conservation of the species because these populations collectively 
comprise an isolated population on the periphery of the species' range 
that possibly possesses unique genetic and phenotypic variation (Forest 
Service, in litt. 1998; Ramirez 2002a). Protecting peripheral 
populations is necessary for maintaining a broad range of genetic 
diversity for the species. Losses of diversity can result in reduced 
evolutionary flexibility and declines in fitness. Threats from 
recreational activities may require special management considerations 
to preserve the area's favorable habitat conditions for the persistence 
of this population.

Unit 22: Upper Mojave River Basin, San Bernardino County

    Unit 22 includes portions of the Mojave River, the West Fork of the 
Mojave River, Horsethief and Little Horsethief Creeks, Grass Valley 
Creek, Deep Creek, and adjacent uplands in the upper Mojave River 
Basin. The unit encompasses approximately 14,450 ac (5,848 ha), of 
which 59 percent is private land, 18 percent is managed by the U.S. 
Army Corps of Engineers in association with a flood control reservoir, 
14 percent is within the San Bernardino National Forest, 8 percent is 
State land, and 1 percent is BLM land. The unit is divided into three 
separate subunits. Subunit 22a includes: (1) Approximately 9.3 mi (18 
km) of Deep Creek from near Holcomb Creek downstream to the confluence 
with the West Fork, (2) approximately 4 mi (6.5 km) of Little 
Horsethief Creek from near the western edge of section 28 (T3N, R5W) 
downstream to the confluence with Horsethief Creek, (3) approximately 
3.4 mi (5.5 km) of Horsethief Creek from the Little Horsethief Creek 
confluence downstream to the West Fork confluence, (4) just over 4.3 mi 
(7 km) of the West Fork of the Mojave River from the Horsethief Creek 
confluence downstream to Mojave River Forks Dam, (5) approximately 2.5 
mi (4 km) of the Mojave River below Mojave River Forks Dam, (6) 
approximately 1.4 mi (2.2 km) of Grass Valley Creek upstream from the 
confluence with the West Fork, and (7) approximately 2.8 mi (4.5 km) of 
Kinley Creek upstream from the Deep Creek confluence. Subunit 22b 
includes approximately 11 mi (18 km) of the Mojave River from just 
above the Upper Narrows (section 14, T5N, R4W) downstream to 
approximately 3.7 mi (6 km) below the Lower Narrows (section 13, T6N, 
R5W). Subunit 22c includes almost 1.9 mi (3 km) of the upper West Fork 
of the Mojave River, above Silverwood Lake, from near the 3,613 ft 
(1,462 m) elevation benchmark downstream to the upper end of the lake.
    This unit is essential because it contains several primary 
constituent elements including low-gradient sandy stream segments that 
support shallow breeding pools, adjacent upland areas for foraging, and 
a hydrologic regime that sufficiently corresponds to natural conditions 
and scours the riparian vegetation, thus providing open areas for 
movements by toads. All of the drainages proposed for designation as 
critical habitat in this unit are occupied by arroyo toads, although 
the current occupancy of the Mojave River within subunit 22b is unknown 
(Tierra Madre Consultants, Inc. 1995; Ramirez 2002b; CNDDB 2003; Forest 
Service, in litt. 2003; Ramirez 2003). Habitat conditions within 
subunit 22b are favorable for toads (E. Ervin, pers. comm. 2003), with 
low-gradient pools, sandy substrates, scattered riparian vegetation, 
and undeveloped uplant habitats. Arroyo toads have been confirmed from 
this area as late as 1982 (Campbell et al. 1996), and unconfirmed 
reports of calling arroyo toads have been made as recently as 1998 (Tim 
Thomas, Biologist, U.S. Fish and Wildlife Service, pers. comm.. 2003). 
However, it has not been extensively surveyed and recent arroyo toad 
observations are lacking along this reach.
    Unit 22 is essential for arroyo toad conservation because it 
contains PCEs that support the largest population of the species on the 
desert side of the mountains (subunit 22a). Summit Valley, which 
encompasses the lower portions of Horsethief Creek and the West Fork of 
the Mojave River, is a broad, flat, alluvial valley that supports a 
substantial arroyo toad population (Ramirez 2003). Providing adequate 
and proper streamflows and protections for the upland alluvial habitats 
would increase the probability for the long-term persistence of this 
large toad population. If adequate streamflows and upland alluvial 
habitats can be maintained, this desert unit would have the most 
favorable conditions of any of the desert units for long-term 
persistence of the large toad population. The downstream portion of 
this unit contains the driest conditions of any unit proposed for 
arroyo toad critical habitat (Teale Data Center 1998; CIMS 2000), which 
suggests that this population may possess unique physiological 
adaptations, such as a reduced rate of evaporative water loss. 
Protection of this area is essential to maintain the range of genetic 
and phenotypic diversity of the species. The presence of exotic 
species, flood control and channel maintenance activities, and 
recreational activity (particularly off-road vehicle use) may create 
the need for special management in this unit.

[[Page 23268]]

Unit 23: Whitewater River Basin, Riverside County

    Unit 23 includes approximately 7.2 mi (11.7 km) of the Whitewater 
River and adjacent uplands, from near Red Dome downstream to Interstate 
10. The unit encompasses approximately 1,997 ac (808 ha), of which 52 
percent is BLM land and 48 percent is private land. The current status 
of arroyo toads in this unit is poorly known. They were observed and 
photographed in the drainage in 1992 (Patten and Myers 1992) but were 
not detected in surveys conducted during the 2000 breeding season 
(Jones and Stokes, in litt. 2000). However, 2000 was generally a bad 
year for arroyo toad breeding activity, particularly in the southern 
half of the species' range, because of below average precipitation and 
subsequent low streamflows. In 2003, a tadpole was identified with 
almost complete certainty to be an arroyo toad near where the Colorado 
River Aqueduct crosses the river (P. Bloom, in litt. 2003). However, 
further surveys should be performed to confirm this finding. Given the 
relatively recent documentation of arroyo toads in this drainage, and 
the continued presence of suitable habitat in the area, we believe it 
is likely that this unit is still occupied.
    Unit 23 supports primary constituent elements such as open sandy 
areas near small areas of slow moving water and adjacent sparse 
riparian habitat for foraging and burrowing. These essential PCEs 
support an isolated desert population on the easternmost periphery of 
the species' range in the Sonoran Desert that may possess unique 
phenotypic and genetic variation that are distinct from other desert 
populations in Units 21 and 22 in the Mohave Desert. Maintaining 
greater genetic diversity creates greater potential for adaptation to 
changing environmental conditions. Threats to this population that may 
require special management considerations include unsuitable water flow 
for breeding and off highway vehicular traffic.

Effects of Critical Habitat Designation

Section 7 Consultation

    Section 7(a) of the Act requires Federal agencies, including the 
Service, to ensure that actions they fund, authorize, permit, or carry 
out do not destroy or adversely modify critical habitat. In our 
regulations at 50 CFR 402.02, we define destruction or adverse 
modification as ``a direct or indirect alteration that appreciably 
diminishes the value of critical habitat for both the survival and 
recovery of a listed species. Such alterations include, but are not 
limited to: Alterations adversely modifying any of those physical or 
biological features that were the basis for determining the habitat to 
be critical.'' However, in a March 15, 2001, decision of the United 
States Court of Appeals for the Fifth Circuit (Sierra Club v. U.S. Fish 
and Wildlife Service et al., F.3d 434), the court found our definition 
of destruction or adverse modification to be invalid. In response to 
this decision, we are reviewing the regulatory definition of adverse 
modification in relation to the conservation of the species.
    Section 7(a) of the Act requires Federal agencies, including the 
Service, to evaluate their actions with respect to any species that is 
proposed or listed as endangered or threatened and with respect to its 
critical habitat, if any is proposed or designated. Regulations 
implementing this interagency cooperation provision of the Act are 
codified at 50 CFR part 402. Section 7(a)(4) of the Act requires 
Federal agencies to confer with us on any action that is likely to 
jeopardize the continued existence of a proposed species or result in 
the destruction or adverse modification of proposed critical habitat. 
Conference reports provide conservation recommendations to assist the 
agency in eliminating conflicts that may be caused by the proposed 
action. The conservation recommendations in a conference report are 
advisory.
    We may issue a formal conference report if requested by a Federal 
agency. Formal conference reports include an opinion that is prepared 
according to 50 CFR 402.14, as if the species were listed or critical 
habitat designated. We may adopt the formal conference report as the 
biological opinion when the species is listed or critical habitat 
designated, if no substantial new information or changes in the action 
alter the content of the opinion (see 50 CFR 402.10(d)).
    If a species is listed or critical habitat is designated, section 
7(a)(2) requires Federal agencies to ensure that activities they 
authorize, fund, or carry out are not likely to jeopardize the 
continued existence of such a 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. Through this consultation, we 
would ensure that the permitted actions do not destroy or adversely 
modify critical habitat.
    If we issue a biological opinion concluding that a project is 
likely to result in the destruction or adverse modification of critical 
habitat, we also provide reasonable and prudent alternatives to the 
project, if any are identifiable. Reasonable and prudent alternatives 
are defined at 50 CFR 402.02 as alternative actions identified during 
consultation that can be implemented in a manner consistent with the 
intended purpose of the action, that are consistent with the scope of 
the Federal agency's legal authority and jurisdiction, that are 
economically and technologically feasible, and that the Director 
believes would avoid destruction or adverse modification of 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 critical 
habitat is subsequently designated and the Federal agency has retained 
discretionary involvement or control over the action or such 
discretionary involvement or control is authorized by law. 
Consequently, some Federal agencies may request reinitiation of 
consultation or conference with us on actions for which formal 
consultation has been completed, if those actions may affect designated 
critical habitat or adversely modify or destroy proposed critical 
habitat.
    Activities on Federal lands that may affect the arroyo toad or its 
critical habitat will require section 7 consultation. Activities on 
private or State lands requiring a permit from a Federal agency, such 
as a permit from the Corps under section 404 of the Clean Water Act, a 
section 10(a)(1)(B) permit from the Service, or some other Federal 
action, including funding (e.g., Federal Highway Administration (FAA) 
or Federal Emergency Management Agency (FEMA) funding), will also 
continue to be subject to the section 7 consultation process. Federal 
actions not affecting listed species or critical habitat and actions on 
non-Federal and private lands that are not federally funded, 
authorized, or permitted do not require section 7 consultation.
    Section 4(b)(8) of the Act requires us to evaluate briefly and 
describe, in any proposed or final regulation that designates critical 
habitat, those activities involving a Federal action that may adversely 
modify such habitat or that may be affected by such designation. 
Activities that may destroy or adversely modify critical habitat would 
be those that alter the primary constituent elements to the extent that

[[Page 23269]]

the value of critical habitat for the conservation of the arroyo toad 
is appreciably reduced. We note that such activities may also 
jeopardize the continued existence of the species.
    Activities that, when carried out, funded, or authorized by a 
Federal agency, may affect critical habitat and require that a section 
7 consultation be conducted include, but are not limited to:
    (1) Regulation of activities affecting waters of the United States 
by the Corps under section 404 of the Clean Water Act;
    (2) Regulation of water flows, damming, diversion, and 
channelization by any Federal agency;
    (3) Road construction and maintenance, right-of-way designation, 
and regulation of agricultural activities on Federal lands (such as 
those managed by the Service, Forest Service, DOD, or BLM);
    (4) Regulation of grazing, mining, and recreation by the BLM, DOD, 
Corps, or Forest Service;
    (5) Regulation of airport improvement activities by the FAA;
    (6) Military training and maneuvers, facilities operations, and 
maintenance on Fort Hunter Liggett and other DOD lands designated as 
critical habitat;
    (7) Licensing of construction of communication sites by the Federal 
Communications Commission; and,
    (8) Funding of activities by the U.S. Environmental Protection 
Agency (EPA), Department of Energy (DOE), FEMA, Federal Highway 
Administration (FHA), or any other Federal agency.
    If you have questions regarding whether specific activities will 
constitute destruction or adverse modification of critical habitat, 
contact the Field Supervisor, Ventura Fish and Wildlife Office or 
Carlsbad Fish and Wildlife Office (see ADDRESSES section). Requests for 
copies of the regulations on listed wildlife and inquiries about 
prohibitions and permits may be addressed to the U.S. Fish and Wildlife 
Service, Branch of Endangered Species, 911 NE 11th Ave., Portland, OR 
97232 (telephone 503/231-2063; facsimile 503/231-6243).
    All lands proposed for designation as critical habitat are within 
the geographic range of the species, all are occupied by the species 
(based on observations made within the last 20 years), and are likely 
to be used by the arroyo toad, whether for foraging, breeding, growth 
of larvae and juveniles, intra-specific communication, dispersal, 
migration, genetic exchange, or sheltering. Thus, we consider all 
proposed critical habitat units to be occupied by the species.
    We recognize that the proposed designation of critical habitat may 
not include all of the habitat areas that may eventually be determined 
to be necessary for the recovery of the species. For these reasons, we 
want to ensure that the public is aware that critical habitat 
designations do not signal that habitat outside the proposed 
designation is unimportant or may not be required for recovery. Areas 
outside the proposed critical habitat designation will continue to be 
subject to conservation actions that may be implemented under section 
7(a)(1) of the Act and to the regulatory protections afforded by the 
section 7(a)(2) jeopardy standard and the prohibitions of section 9 of 
the Act. Critical habitat designations made on the basis of the best 
available information at the time of designation will not control the 
direction and substance of future recovery plans, HCPs, or other 
species conservation planning efforts if new information available to 
these planning efforts calls for a different outcome.

Application of Section 4(a)(3)(B) and Exclusions Under Section 4(b)(2) 
of the Act

    The recent amendments to Section 4(a)(3) of the Endangered Species 
Act (Pub. L. 108-136) address the relationship of Integrated Natural 
Resources Management Plans (INRMPs) to critical habitat. The new 
provision prohibits the Service from designating 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 INRMP prepared under section 101 of the Sikes Act (16 U.S.C. 670a), 
if the Secretary of the Interior determines in writing that such plan 
provides a benefit to the species for which critical habitat is 
proposed for designation. Both Camp Pendleton and Fallbrook Naval 
Weapons Station have completed INRMPs. The application of section 
4(a)(3) to these military lands and our decision to include them in 
this proposed designation are discussed below under Relationship to 
Lands Managed by the DOD--Exclusions under Section 4(a)(3)(B) and 
4(b)(2) of the Act.
    Section 4(b)(2) of the Act states that critical habitat shall be 
designated, and revised, on the basis of the best available scientific 
data after taking into consideration the economic impact, the impact on 
national security, and any other relevant impact of specifying any 
particular area as critical habitat. An area may be excluded from 
critical habitat if it is determined that the benefits of exclusion 
outweigh the benefits of specifying the particular area as critical 
habitat, unless the failure to designate such area as critical habitat 
will result in the extinction of the species.
    In our critical habitat designations, we use the provisions 
outlined in section 4(b)(2) of the Act to evaluate those specific areas 
that we are considering proposing as critical habitat as well as for 
those areas that are formally proposed for designation as critical 
habitat. We have excluded lands under section 4(b)(2) within military 
installations where designation could interfere with mission essential 
training activities or impact national security. In addition, we have 
excluded lands under section 4(b)(2) that are covered by the following 
types of plans if they provide assurances that the conservation 
measures they provide will be implemented and effective: (1) Legally 
operative HCPs that cover the species, (2) draft HCPs that cover the 
species and have undergone public review and comment (i.e., pending 
HCPs), (3) Tribal conservation plans that cover the species, (4) State 
conservation plans that cover the species, and (5) National Wildlife 
Refuge System Comprehensive Conservation Plans.
    We have considered, but are excluding from proposed critical 
habitat for the arroyo toad, the following areas under section 4(b)(2): 
Mission-essential training areas on Camp Pendleton and Fort Hunter-
Liggett; lands within approved subarea plans of the San Diego Multiple 
Species Conservation Program (MSCP); and lands covered by the Orange 
County Central-Coastal NCCP/HCP, the San Diego Gas and Electric (SDG&E) 
NCCP/HCP, and the proposed Western Riverside Multiple Species Habitat 
Conservation Plan (MSHCP). We are proposing some lands that are managed 
by the DOD as critical habitat for the arroyo toad. These include 
nontraining and cantonment areas on Camp Pendleton, nontraining areas 
on Fort Hunter Liggett, and Fallbrook Naval Weapons Station. We are 
also proposing some Tribal lands within the Pala, Rincon, Sycuan, Mesa 
Grande, and the Capitan Grande Indian Reservation as critical habitat. 
Our evaluation of land within each of these categories under section 
4(b)(2) follows.
    Table 3 shows the approximate proposed critical habitat, essential 
area, and excluded areas. Table 4 shows the planning and preserve areas 
within NCCP/HCPs discussed in this proposal.

  Station in Riverside County, California. However, the size of this
  planning area is not specified in SDG&E's Subregional Natural
  Community Conservation Plan. Based on the Plan's forecasting, it is
  estimated that SDG&E will impact 124 acres within 25 years following
  the receipt of their Section 10(a)(1)(B) permit. Since the future
  cannot be accurately predicted, the Service has authorized up to 400
  acres (162 ha) of impact over a 55-year period under the Section
  10(a)(1)(B) permit (USFWS 1995).

Approved Habitat Conservation Plans--Exclusions Under Section 4(b)(2)

Regional HCPs

    Section 4(b)(2) of the Act requires us to consider other relevant 
impacts, in addition to economic impacts, when designating critical 
habitat. Section 10(a)(1)(B) of the Act authorizes us to issue permits 
for the take of listed wildlife species incidental to otherwise lawful 
activities. Development of an HCP is a prerequisite for the issuance of 
an incidental take permit pursuant to section 10(a)(1)(B) of the Act. 
An incidental take permit application must be supported by an HCP that 
identifies conservation measures that the permittee agrees to implement 
for the species to minimize and mitigate the impacts of the permitted 
incidental take.
    HCPs vary in size and may provide for incidental take coverage and 
conservation management for one or many federally listed species. 
Additionally, more than one applicant may participate in the 
development and implementation of an HCP. Some areas occupied by the 
arroyo toad involve several very complex HCPs that address multiple 
species, cover large areas, and are very important to many 
participating permittees. Large regional HCPs expand upon the basic 
requirements set forth in section 10(a)(1)(B) of the Act because they 
reflect a voluntary, cooperative approach to large-scale habitat and 
species conservation planning. Many of the large regional HCPs in 
southern California have been, or are being, developed to provide for 
the conservation of numerous federally listed species and unlisted 
sensitive species and the habitat that provides for their biological 
needs. These HCPs are designed to proactively implement conservation 
actions to address future projects that are anticipated to occur within 
the planning area of the HCP. However, given the broad scope of these 
regional HCPs, not all projects envisioned to potentially occur may 
actually take place.
    In the case of approved regional HCPs and accompanying Implementing 
Agreements (IAs) (e.g., those sponsored by cities, counties, or other 
local jurisdictions) that provide for incidental take coverage for the 
arroyo toad, a primary goal of these regional plans is to provide for 
the protection and management of habitat essential for the species' 
conservation while directing development to other areas. The regional 
HCP development process provides an opportunity for more intensive data 
collection and analysis regarding the use of particular habitat areas 
by the arroyo toad. The process also enables us to conduct detailed 
evaluations of the importance of such lands to the long-term survival 
of the species in the context of constructing a system of interlinked 
habitat blocks that provide for its biological needs.
    We have considered, but have not proposed as critical habitat, 
lands in approved subarea plans within the San Diego MSCP, the Central-
Coastal NCCP/HCP in Orange County, and the SDG&E NCCP/HCP under Section 
4(b)(2). These approved and legally operative HCPs include portions of 
five proposed critical habitat units (8, 16, 17, 18, and 19). We 
believe the benefits of excluding lands within these legally operative 
HCPs from the proposed critical habitat designations will outweigh the 
benefits of including them. The following represents our rationale for 
excluding these areas.
    Portions of Unit 8 are excluded under section 4(b)(2) from proposed 
critical habitat because they are within the Orange County Central 
Coastal Subregional NCCP/HCP. The Central-Coastal NCCP/HCP in Orange 
County was developed in cooperation with numerous local and State 
jurisdictions and agencies, and participating landowners including the 
cities of Anaheim, Costa Mesa, Irvine, Orange, and San Juan Capistrano; 
Southern California Edison; Transportation Corridor Agencies; The 
Irvine Company; California Department of Parks and Recreation; 
Metropolitan Water District of Southern California; and the County of 
Orange. Approved in 1996, the Central-Coastal NCCP/HCP provides for the 
establishment of approximately 38,738 ac (15,677 ha) of reserve lands 
for 39 Federal or State listed and unlisted sensitive species within 
the 208,713 ac (84,463 ha) planning area. We issued an incidental take 
permit under section 10(a)(1)(B) of the Act that provides conditional 
incidental take authorization for the arroyo toad for all areas within 
the Central-Coastal Subregion except the North Ranch Policy Plan area. 
This take authorization only applies to smaller arroyo toad 
populations, reintroduced populations, or populations that have 
expanded due to NCCP Reserve management. It also requires 
implementation of a mitigation plan to relocate toads to protected 
areas within the Reserve, when necessary. The Central-Coastal NCCP/HCP 
provides for monitoring and adaptive management of the arroyo toad and 
its habitat within the Reserve System. Adaptive management activities 
may include a program to control predators, such as bullfrogs, clawed 
frogs, and non-native fishes. It may also include a

[[Page 23271]]

program of closing dirt road crossings without culverts or upgrading 
such crossings with concrete fords and/or culverts on publicly owned 
lands outside the Reserve System if baseline monitoring indicates such 
measures would likely be effective.
    The North Ranch Policy Plan area was excluded from take 
authorization provided for the Central Coastal NCCP/HCP due to a lack 
of detailed biological information and specific conservation 
commitments at the time of adoption of the NCCP/HCP. We have since 
determined that available arroyo toad habitat within the North Ranch 
Policy Plan area is essential to the conservation of the arroyo toad 
because it helps support a viable Santa Ana Mountain arroyo toad 
population. In 2002, the owner, The Irvine Company granted a 
conservation easement over a portion of the North Ranch Policy Plan 
Area that covers arroyo toad proposed critical habitat areas to The 
Nature Conservancy. We recognize that the Irvine Company has taken 
steps to conserve the North Ranch Policy Area, including a $10 million 
management endowment. The conservation easement provides adequate 
protection for arroyo toad habitat within this unit. As a result, we 
are excluding the North Ranch Policy Plan area from proposed critical 
habitat.
    Portions of Units 16, 17, 18, and 19 are also excluded under 
section 4(b)(2) from proposed critical habitat because they are within 
the approved San Diego MSCP/HCP in southwestern San Diego County. The 
San Diego MSCP plan encompasses more than 582,000 ac (236,000 ha) and 
reflects the cooperative efforts of the local jurisdictions, the State, 
the building industry, and environmentalists. The San Diego MSCP 
provides for the establishment over the permit term of approximately 
171,000 ac (69,573 ha) of preserve areas to provide conservation 
benefits for 85 federally listed and sensitive species. The San Diego 
MSCP and its approved subarea plans provide measures to conserve known 
arroyo toad populations within the Sweetwater River, Otay River, Santa 
Ysabel Creek in San Pasqual Valley, San Vicente Creek above the San 
Vicente Reservoir, and Cottonwood Creek in Marron Valley. Area-specific 
management directives for MSCP subarea plans must address the 
conservation of the arroyo toad by protecting and maintaining 
sufficient, suitable, low-gradient sandy stream habitat to meet 
breeding requirements; preserving sheltering and foraging habitats 
within 0.6 mi (1 km) of occupied breeding habitat within designated 
preserve land; controlling nonnative predators; and controlling human 
impacts within designated preserves. Several of these management plans 
are currently under development, including those for Marron and San 
Pasqual Valleys. These lands are to be permanently maintained and 
managed for the benefit of the arroyo toad and other covered species.
    One exception to the MSCP/HCP exclusion concerns the reach of the 
Sweetwater River between Loveland and Sweetwater Reservoirs within the 
County of San Diego's MSCP plan. This area is affected by activities 
(e.g., reservoir water transfers) that are outside the authority of, 
and thus not subject to, the approved County of San Diego MSCP subarea 
plan. Therefore, we are including this limited reach of the Sweetwater 
River as proposed critical habitat.
    The SDG&E NCCP/HCP encompasses San Diego County west of the desert, 
the portion of Orange County within SDG&E's existing service territory, 
and the SDG&E Moreno Compressor Station in Riverside County. The 
section 10(a)(1)(B) permit covers the arroyo toad and 17 other species 
listed at the time the plan was approved in 1995. The NCCP/HCP allows 
SDG&E to impact through habitat modification a maximum of 400 ac (162 
ha) of natural land over a 55-year permit period. In general, impacts 
resulting from the operation, maintenance, and expansion of SDG&E's 
facilities are limited to narrow strips (typically 200 ft (61 m) wide 
or less) along gas and electric transmission lines, including periodic 
placement of substations and regulator stations with a footprint of up 
to 20 ac (8.1 ha). Effects of the plan are minimal because impacts 
would generally be small, and the Plan prioritizes avoidance, 
minimization, and mitigation (in that order) for any potential impacts. 
The Plan preserves individual toads and habitats to maximum extent 
practicable and preserves corridors connecting habitats. It may also 
reclaim and restore habitats that may include the species. Critical 
habitat is not proposed for the arroyo toad within these 400 ac (162 
ha). However, these areas may still appear on our critical habitat maps 
as an artifact of mapping scale.
(1) Benefits of Inclusion
    Under section 7, critical habitat designation will provide little 
additional benefit to the arroyo toad within the boundaries of these 
approved HCPs. The principal benefit of any designated critical habitat 
is that federally funded or authorized activities in such habitat that 
may affect it require consultation under section 7 of the Act. Such 
consultations ensure that adequate protection is provided to avoid 
adverse modification of critical habitat. Currently approved HCPs and 
NCCP/HCPs that cover the toad are designed to ensure the conservation 
of the species within the plan area, and incorporate special management 
and protection for arroyo toad habitat within plan boundaries. The 
adequacy of plan measures to protect the toad and its habitat has 
undergone thorough evaluation in the section 7 consultations completed 
prior to approval of the plans.
    Development and implementation of these NCCCP/HCPs and HCPs has 
provided other important conservation benefits for the toad, including 
the development of biological information to guide conservation efforts 
and assist in the species' recovery. The educational benefits of 
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 these NCCP/HCPs and HCPs. Specifically, each of these HCPs 
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 these approved HCPs. Federal actions in areas 
occupied by the toad will still require consultation under section 7 of 
the Act.
(2) Benefits of Exclusion
    We have determined that the benefits of excluding lands within 
approved HCPs from proposed critical habitat designation are generally 
more substantial than including them. The benefits of excluding HCPs 
from critical habitat designation include relieving landowners, 
communities, and counties 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

[[Page 23272]]

voluntary HCP process, because it may result in additional regulations 
requiring more of them than other parties who have not voluntarily 
participated in species conservation. 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 HCPs generally from critical habitat apply fully to the 
approved NCCP/HCP and HCPs discussed above that cover the arroyo toad.
    A related benefit of excluding lands within approved HCPs that 
cover the arroyo toad from proposed 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 toad and its habitat. By excluding these 
lands, we preserve our current partnerships and encourage additional 
conservation actions in the future.
(3) Benefits of Exclusion Outweigh the Benefits of Inclusion
    In general, we find that the benefits of critical habitat 
designation on lands within approved HCPs are small while the benefits 
of excluding such lands from designation of critical habitat are 
substantial. After weighing the small benefits of including these lands 
against the much greater benefits derived from excluding them, 
including relieving property owners of an additional layer of approvals 
and regulation and encouraging the pursuit of additional conservation 
partnerships, it is our intent to exclude lands within approved HCPs 
from proposed critical habitat designation. We have reviewed and 
evaluated the approved Orange County Central Coastal Subregional NCCP/
HCP, the SDG&E NCCP/HCP, and the San Diego MSCP HCPs and NCCP/HCPs and 
find that the benefits of exclusion outweigh the benefits of proposing 
portions of Units 8, 16, 17, 18, and 19 as critical habitat.
    Each of these HCPs includes the arroyo toad as a covered species 
and provides protection for the arroyo toad and its associated habitat 
in perpetuity. They also preserve the partnerships that we developed 
with the local jurisdictions and project proponent in the development 
of the HCPs and NCCP/HCPs.
    The educational benefits of critical habitat, including informing 
the public about areas that are important for the long-term survival 
and conservation of the species, have been provided by the public 
notice and comment procedures required to establish these HCPs and 
NCCPs. For these reasons, we believe that proposing critical habitat on 
lands covered by the identified HCPs and NCCP/HCPs has little benefit 
and is outweighed by the more substantial benefits of excluding the 
lands from critical habitat. Because of the management and protection 
provided for the toad and its habitat within the approved plan areas, 
the exclusion of essential toad habitat within approved HCPs and NCCPs/
HCPs will not result in the extinction of the species.

Relationship of Critical Habitat to the Draft Western Riverside 
Multiple Species Habitat Conservation Plan (MSHCP)

     The Draft Western Riverside Multiple Species Habitat Conservation 
Plan (MSHCP) has been in development for several years. In contrast to 
the other HCPs under development, which contain essential toad habitat 
and are identified in Table 4, the Western Riverside MSHCP is 
essentially completed and the Service is very close to taking final 
action on the County of Riverside's incidental take permit application. 
Participants in this HCP include 14 cities; the County of Riverside, 
including the Riverside County Flood Control and Water Conservation 
Agency, Riverside County Transportation Commission, Riverside County 
Parks and Open Space District, and Riverside County Waste Department; 
the California Department of Parks and Recreation; and Caltrans. The 
Western Riverside MSHCP is also being proposed as a subregional plan 
under the State's NCCP and is being developed in cooperation with CDFG. 
Within the 1.26-million acre (510,000-ha) planning area of the MSHCP, 
approximately 153,000 ac (62,000 ha) of diverse habitats are proposed 
for conservation. The proposed conservation of 153,000 ac (62,000 ha) 
will complement other existing natural and open space areas (e.g., 
State Parks, Forest Service, and County Park Lands).
    The County of Riverside and the participating jurisdictions have 
signaled their sustained support for the Western Riverside MSHCP as 
evidenced by the November 5, 2002, passage of a local bond measure to 
fund the acquisition of land in support of the MSHCP. On November 15, 
2002, we published a Notice of Availability of a Draft Environmental 
Impact Report (EIS/EIR) and Receipt of and Application for an 
Incidental Take Permit in the Federal Register. Public comment on these 
documents was accepted until January 14, 2003. Additionally, on June 
17, 2003, the County of Riverside Board of Supervisors voted 
unanimously to support the completion of the Western Riverside MSHCP.
    The Western Riverside MSHCP proposes conservation actions within 
the planning area, including surveying for additional populations and 
habitat protection, to ensure the long-term conservation of the arroyo 
toad. Although the MSHCP is not yet approved and implemented, 
significant progress has been achieved in the development of this HCP, 
including circulation of the final EIS/EIR, the solicitation of public 
review and comment, and the initiation of the intra-Service Section 7 
consultation for those species identified for coverage within the draft 
plan. We are excluding portions of Unit 9 and 13 from proposed critical 
habitat pursuant to section 4(b)(2) of the Act because they are within 
the planning area boundary for the proposed Western Riverside MSHCP. 
However, we are proposing Unit 10 and other portions of Units 9 and 13 
on U.S. Forest Service lands within the planning area boundary of the 
Western Riverside MSHCP as critical habitat because the activities of 
Federal agencies are not covered under a section 10(a)(1)(B) permit. 
Our analysis for excluding portions of Units 9 and 13 from proposed 
critical habitat is outlined below.
(1) Benefits of Inclusion
    As stated previously, the benefits of designating critical habitat 
on lands within the boundaries of HCPs are normally small. HCPs 
generally include management measures and protections designed to 
protect, restore, monitor, manage, and enhance the habitat to benefit 
the conservation of the covered species. The draft Western Riverside 
MSHCP seeks to accomplish these goals for the arroyo toad through the 
implementation of specific conservation measures. The principal benefit 
of designating critical habitat is that federally authorized or funded 
activities that may affect a species' critical habitat would require 
consultation with us under section 7 of the Act. In the case of the 
proposed Western Riverside MSHCP, we must evaluate the impact of the 
plan on the species for which the

[[Page 23273]]

participants are seeking incidental take permits, pursuant to section 7 
of the Act. Under section 7, proposed actions that would adversely 
modify or destroy designated critical habitat cannot go forward unless 
they are altered to eliminate the adverse modification or destruction 
of critical habitat.
    An important objective of the Western Riverside MSHCP is to 
implement measures, including monitoring and management, necessary to 
conserve important habitat for the arroyo toad within the plan's 
boundaries. Thus, the purposes of the Western Riverside MSHCP are 
consistent with the purpose served by undergoing consultation under 
section 7, which is to ensure that critical habitat of the toad is not 
adversely modified by a proposed Federal action. Because issuance of an 
incidental take permit (ITP) under section 10 is a Federal action, 
prior to approving the Western Riverside MSHCP, we must complete an 
internal section 7 consultation for every species, including the arroyo 
toad proposed to be covered under the proposed plan and permit. The 
consultation requires us to analyze the impacts of the proposed ITP and 
HCP on the toad and its essential habitat within the plan boundaries, 
whether or not that habitat has been officially designated as critical 
habitat. Therefore, including essential toad habitat subject to 
provisions of the proposed Western Riverside MSHCP as critical habitat 
would provide little benefit to the arroyo toad because the potential 
impacts to the species' essential habitat within the MSHCP area are 
already addressed under the plan and will be analyzed in our internal 
section 7 consultation on the proposed ITP.

(2) Benefits of Exclusion

    Excluding from proposed critical habitat lands within Units 9 and 
13 that are covered by the within the Western Riverside MSHCP will 
provide several benefits. Exclusion of the lands from the final 
designation will allow us to continue working with the participants in 
a spirit of cooperation and partnership. In the past, HCP applicants 
and participants in voluntary conservation programs have generally 
viewed the designation of critical habitat as having a potential 
negative regulatory effect that discourages voluntary, cooperative and 
proactive efforts to conserve listed species and their habitats by non-
Federal parties. They generally view designation of critical habitat as 
an indication by the Federal government that their proactive actions to 
protect the species and its habitat are inadequate. Excluding these 
areas from the perceived negative consequences of critical habitat will 
likely encourage other jurisdictions, private landowners, and other 
entities to work cooperatively with us to develop HCPs and conservation 
plans, which will provide the basis for future opportunities to 
conserve species and their essential habitat.
(3) Benefits of Exclusion Outweigh the Benefits of Inclusion
    We believe the analysis conducted to evaluate the benefits of 
excluding HCPs from critical habitat versus the benefits of including 
these lands, which was previously discussed for the exclusion of 
approved HCPs, is applicable and appropriate for the exclusion of HCPs 
that are in the final permit decision phase, such as the Western 
Riverside MSHCP. In the event that the Service does not grant coverage 
for this species under the Western Riverside MSHCP, we will include the 
areas essential to the conservation of the arroyo toad in Units 9, 10, 
and 13 in the final designation of critical habitat. Excluding arroyo 
toad habitat within the plan area will preserve the partnerships that 
we have developed with the local jurisdictions and project proponents 
in the development of the HCP. Because of the permanent protection and 
management measures provided in the plan, exclusion of essential toad 
habitat within the plan area will not result in the extinction of the 
arroyo toad.
    There are currently several other regional NCCP/HCP efforts under 
way in southern California that have not yet been completed but which 
are intended, upon approval, to provide conservation benefits to the 
arroyo toad. Lands within these HCPs, which are in the early stages of 
formulation, are not excluded from consideration for proposed critical 
habitat as we have yet to receive a permit application from the 
participants, environmental analysis of the plans has not been 
completed and the plans have not been released for public review and 
comment. The proposed Southern Subregion NCCP/HCP in Orange County 
encompasses approximately 128,000 ac (51,799 ha) in its planning area. 
Jurisdictions and private landowners within the study area include the 
cities of Rancho Santa Margarita, Mission Viejo, San Juan Capistrano, 
San Clemente, and Rancho Mission Viejo. The arroyo toad is being 
proposed as one of the species covered under this plan. The Coachella 
Valley Multiple Species HCP/NCCP in Riverside County encompasses 
approximately 1,200,000 ac (479,139 ha) in its planning area. 
Participants include the Coachella Valley Association of Governments; 
Federal, State, and County agencies; University of California, 
Riverside; Coachella Valley Mountains Conservancy; and unincorporated 
private lands. The arroyo toad is also being proposed as one of the 
covered species under this plan.
    In addition to the two plans identified above, the Multiple Habitat 
Conservation Program (MHCP) in northwestern San Diego County 
encompasses approximately 112,000 ac (45,324 ha) within the study area 
and includes lands we are proposing as critical habitat for the arroyo 
toad. Currently, seven cities are participating in the development of 
the MHCP. However, the arroyo toad is not proposed as a covered species 
in this plan.

Relationship of Indian Reservations and Exclusions Under 4(b)(2)

    Section 4(b)(2) of the Act requires us to gather information 
regarding the designation of critical habitat and the effects thereof 
from all relevant sources, including Indian Pueblos and Tribes. In 
accordance with Secretarial Order 3206, ``American Indian Tribal 
Rights, Federal-Tribal Trust Responsibilities, and the Endangered 
Species Act'' (June 5, 1997); the President's memorandum of April 29, 
1994, ``Government-to-Government Relations with Native American Tribal 
Governments;'' and Executive Order 13175, we recognize the need to 
consult with federally recognized Tribes on a government-to-government 
basis when considering the designation of critical habitat in an area 
that may impact Tribal trust resources, tribally-owned fee lands, or 
the exercise of Tribal rights. Critical habitat shall not be designated 
in such areas unless it is determined essential to conserve a listed 
species. In designating critical habitat, we must evaluate and document 
the extent to which the conservation needs of the listed species can be 
achieved by limiting the designation to other lands. On January 29, 
2004, the Service sent letters to the Mesa Grande Band of Mission 
Indians, Pala Band of Mission Indians, Sycuan Band of the Kumeyaay 
Nation, Viejas Band of Kumeyaay Indians, Rincon Band of Mission 
Indians, and the Barona Indian Reservation seeking consultation on the 
possible proposal of critical habitat within their Reservations. On 
March 9, 2004, the Service met with the Pala Banda of Mission Indians 
to discuss areas that should or should not be proposed as critical 
habitat. We are currently still attempting to arrange meetings with 
these Tribes in order to

[[Page 23274]]

discuss matters regarding critical habitat.
    We consider portions of the Pala, Rincon, Sycuan, Mesa Grande, and 
Capitan Grande (which is jointly administered by the Viejas and Barona 
Tribes) Indian Reservation lands to be essential, and are therefore 
proposing these areas as critical habitat for the arroyo toad. The 
following represents our rationale for including these Reservations as 
proposed critical habitat.
(1) Benefits of Inclusion
    Essential, high-quality habitat exists on the Pala, Rincon, Sycuan, 
Mesa Grande, and Capitan Grande Indian Reservations. The Pala and 
Rincon Indian Reservations support core arroyo toad populations that 
are critical to maintaining the viability of toads along the San Luis 
Rey River. Pala, Sycuan, Mesa Grande, and Capitan Grande Reservations 
also include lands that are essential to maintaining the connectivity 
of proposed critical habitat with habitat of known arroyo toad 
populations outside the boundaries of the reservations. The long-term 
viability of these populations would be severely at risk should the 
habitat supporting these populations become fragmented.
    The primary benefit of any critical habitat with regard to 
activities that require consultation pursuant to section 7 of the Act 
is to ensure that the activity will not destroy or adversely modify 
designated critical habitat. Because many activities on Tribal lands 
involve activities authorized, funded or carried out by a Federal 
agency, and in particular, the Bureau of Indian Affairs, the likelihood 
of future Section 7 consultations that would address loss of essential 
arroyo toad habitat on the reservations is high. Where Tribes have 
management plans in place that provide adequate protection for the 
species, the benefits of proposing critical habitat on Indian 
Reservations are minimal because implementation of a management plan 
should ensure the long-term survival of the covered species. However, 
there are currently no management plans in place that address the 
conservation needs of the arroyo toad and its habitat on any of the 
Indian Reservations considered essential for the arroyo toad. An 
additional benefit for including Indian Reservations as critical 
habitat are the educational benefits that proposing critical habitat 
will provide Tribes by informing them of areas that are important to 
the conservation of this species.
(2) Benefits of Exclusion
    The benefits of excluding Indian Reservations from critical habitat 
designation include relieving Tribes of any additional regulatory 
burden that may result solely from such designation. Designation of 
critical habitat may undermine future conservation efforts and 
partnerships and discourage Tribes from developing species and habitat 
management plans. Designation of critical habitat could also be viewed 
as a disincentive by Tribes contemplating developing HCPs in the 
future. Excluding Tribal lands could help preserve our current 
partnerships and set the stage for additional conservation actions in 
the future.
    Further, projects on Indian Reservations with a Federal nexus will 
trigger a consultation under section 7 of the Act if the action may 
affect the arroyo toad or its designated critical habitat. Through 
section 7 consultation, we would address the conservation of the arroyo 
toad and its habitat to ensure that actions undertaken, authorized, or 
permitted by a Federal agency would not jeopardize the continued 
existence of the species or adversely modify critical habitat. In light 
of the Federal government's trust responsibility for Tribal trust 
resources and lands, and the likelihood of future Federal nexuses that 
would trigger section 7 consultations with regard to those resources 
and lands, the Tribes may view the designation of Indian Reservations 
as critical habitat as creating an additional regulatory burden.
(3) Benefits of Inclusion Outweigh the Benefits of Exclusion
    After weighing the benefits of proposing critical habitat on the 
Pala, Rincon, Sycuan, Mesa Grande, and the Capitan Grande Indian 
Reservations against the benefits of excluding them, we find the 
benefits of proposing these lands outweigh the benefits of excluding 
them primarily because these Reservation lands support important core 
arroyo toad populations (Rincon and Pala) and/or areas that are 
essential for maintaining the connectivity of occupied high quality 
arroyo toad habitat outside the boundaries of the Reservations (Mesa 
Grande, Sycuan, Pala, and Capitan Grande). Further, none of these 
Tribes has developed a management plan that addresses the conservation 
needs of the arroyo toad. We are committed to working with these Tribes 
to develop management plans for the arroyo toad. In the event that one 
or more adequate management plans are developed before the final 
designation of critical habitat, we will consider excluding Reservation 
lands covered by the plans from final critical habitat. We have 
restricted the amount of Reservation lands included as proposed 
critical habitat to the minimum essential for the conservation of the 
species. These essential areas consist of habitat supporting core 
populations or connectivity among populations.

Relationship to Lands Managed by the DOD--Exclusions Under Section 
4(a)(3)(B) and 4(b)(2) 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, by November 17, 2001, an INRMP. An INRMP integrates 
implementation of the military mission of the installation with 
stewardship of the natural resources found there. 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. We consult with the military 
on the development and implementation of INRMPs for installations with 
listed species.
    As discussed above, Section 318 of fiscal year 2004 the National 
Defense Authorization Act (Pub. L. 108-136) amended the Endangered 
Species by adding a new section 4(a)(3)(B). This provision prohibits 
the Service from designating 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 INRMP prepared under 
section 101 of the Sikes Act (16 U.S.C. 670a), if the Secretary of the 
Interior determines in writing that such plan provides a benefit to the 
species for which critical habitat is proposed for designation.
    The bases where we identified habitat essential for the 
conservation of the arroyo toad are Camp Pendleton, Fallbrook Naval 
Weapons Station, and Fort Hunter Liggett. Critical habitat was 
previously designated for the arroyo toad, and was in effect from 
February 2001 through October 2003, on Fort Hunter Liggett, Fallbrook 
Naval Weapons Station, and those portions of Camp Pendleton that were 
leased to a third party and not used for military purposes. Camp 
Pendleton and Fallbrook Naval Weapons Station have approved INRMPs. We 
will examine those INRMPs to determine coverage for

[[Page 23275]]

the arroyo toad. On completion of that examination, we may exclude 
these areas from our final critical habitat designation under section 
4(a)(3)(B). If, prior to the final designation of critical habitat for 
the arroyo toad, the U.S. Army (Army) completes its INRMP or Endangered 
Species Management Plan for the arroyo toad at Fort Hunter Liggett, 
these lands will be considered for exclusion under section 4(a)(3)(B).

Mission-Essential Training Areas at Marine Corps Base Camp Pendleton--
Exclusions Under Section 4(b)(2)

    Section 4(b)(2) of the Act as recently amended by section 318 of 
the National Defense Authorization Act of 2004 expressly requires the 
Secretary to take into account the impact on national security of 
specifying any particular area as critical habitat. This is in addition 
to the section 4(a)(3)(B) provisions relating to INRMPS referenced 
above. The Marine Corps operates Camp Pendleton as an amphibious 
training base that promotes the combat readiness of military forces and 
is the only West Coast Marine Corps facility where amphibious 
operations can be combined with air, sea, and ground assault training 
activities year-round.
    The arroyo toad occurs primarily in three watersheds on Camp 
Pendleton: Santa Margarita, San Onofre, and San Mateo. Arroyo toad 
populations within these watersheds on Camp Pendleton are essential to 
the conservation of the species because these watersheds retain 
relatively natural hydrological processes and functions. The Santa 
Margarita watershed is one of the least altered major watersheds 
occupied by the species throughout its range. Also, the lower portions 
of all three watersheds represent the last remaining coastal plain 
areas where significant numbers of arroyo toads occur within 6 mi (10 
km) of the coast and in coastal marsh zones. Elsewhere throughout the 
species' range, urban and agricultural development has been largely 
responsible for extirpating arroyo toad populations in low coastal 
plain areas.
    The Marine Corps consults with us under section 7 of the Act for 
activities that may affect federally listed species on Camp Pendleton. 
On October 30, 1995, we issued a biological opinion regarding the 
Marine Corps' programmatic activities and conservation plans in 
riparian and estuarine/beach ecosystems on Camp Pendleton (Service 
1995). At issue were the impacts that ongoing and planned training 
activities, infrastructure maintenance activities, several construction 
projects, and a Riparian and Estuarine Ecosystem Conservation Plan may 
have on six federally listed species, including the arroyo toad. Since 
then, we have requested in a letter dated February 9, 2000, that the 
programmatic instructions and conservation measures in the plan be 
revised to avoid and minimize potential adverse effects to the arroyo 
toad. These revisions included, but were not limited to, the 
``implementation of a base-wide non-native predatory species control 
program, removal of nonessential road crossings, modification of 
existing and new road crossings, removal of unnecessary structures and 
hardscape within arroyo toad breeding and nonbreeding habitats, and 
guidelines on the use of toad exclusion fencing.''
    Additionally, Camp Pendleton's programmatic conservation plan for 
riparian and estuarine/beach ecosystems does not address arroyo toads 
in upland habitats. On March 30, 2000, at the request of the Marine 
Corps, we initiated formal consultation regarding Marine Corps 
activities on upland areas of Camp Pendleton. The consultation covers 
approximately 125,000 ac (50,500 ha) of land and addresses numerous 
activities that currently are expected to occur within the upland areas 
of Camp Pendleton, including combat readiness operations, air 
operations, vehicle operations, facility maintenance and operations, 
fire management, recreational activities, and housing. The upland 
consultation for the arroyo toad and other species is not yet 
completed. We are currently working cooperatively with Camp Pendleton 
to facilitate the completion of the upland consultation. Upon 
completion, this consultation will address the 93 percent of Camp 
Pendleton not included in our 1995 opinion concerning riparian and 
estuarine/beach ecosystems (Service 1995). In order to continue its 
critical training mission pending completion of the consultation, the 
Marine Corps has implemented a set of ``programmatic instructions'' to 
minimize adverse effects to the arroyo toad.
(1) Benefits of Inclusion
    The primary benefit of any critical habitat with regard to 
activities that require consultation pursuant to section 7 of the Act 
is to ensure that the activity will not destroy or adversely modify 
designated critical habitat. The primary benefit of proposing critical 
habitat for the arroyo toad on mission-essential training lands on Camp 
Pendleton is limited. Designating critical habitat would identify lands 
essential to the conservation of the species and require the Marine 
Corps to consult with us under section 7 to ensure proposed activities 
are not likely to destroy or adversely modify arroyo toad critical 
habitat. However, we are already in formal consultation with the Marine 
Corps regarding their upland activities to ensure that current and 
proposed actions will not jeopardize the species' continued existence, 
and that consultation will take into account the essential habitat 
requirements of the species. Therefore, we do not believe that 
designation of mission-essential training areas on Camp Pendleton as 
critical habitat will significantly benefit the arroyo toad beyond the 
protection already afforded the species under the Act. The educational 
benefits of critical habitat include informing the Marine Corps of 
areas that are essential to the conservation of listed species.
(2) Benefits of Exclusion
    In contrast to the absence of a significant benefit resulting from 
designation of Camp Pendleton training areas as critical habitat, there 
are substantial benefits to excluding these areas from critical 
habitat. If we propose or designate critical habitat within these 
training areas, the Marine Corps may be required to conference or 
consult on activities that affect the proposed or designated critical 
habitat. The requirement to conference or consult on activities within 
mission-essential training areas could delay and impair the ability of 
the Marine Corps to conduct effective amphibious training activities 
and limit Camp Pendleton's unique status as the only West Coast Marine 
Corps facility where such amphibious training operations can be 
conducted year round. Such restrictions on Camp Pendleton's military 
training mission would negatively affect national security.
(3) Benefits of Exclusion Outweigh the Benefits of Inclusion
    Based on the impact on national security and the Marine Corps' need 
to maintain a high level of readiness and fighting capabilities, we 
have considered but have not proposed critical habitat on essential 
lands identified as mission-essential training areas on Camp Pendleton. 
We find that the benefits of excluding these areas from critical 
habitat outweigh the benefits of including them. We further find that 
the exclusion of these areas will not lead to the extinction of the 
arroyo toad because we will continue to consult with the Marine Corps 
under section 7 on any actions that may affect the toad to ensure that 
such actions are not likely to jeopardize the continued existence of 
the species.

[[Page 23276]]

Fort Hunter Liggett and Exclusion Under Section 4(b)(2)

    We have considered, but have not proposed, to include mission-
essential training areas on Fort Hunter Liggett as critical habitat for 
the arroyo toad under section 4(b)(2) of the Act, because designation 
of critical habitat could adversely impact national security. The Army 
conducts training operations using landing fields, tanks, machine guns, 
grenade launchers, and more at Fort Hunter Liggett. The Army has stated 
that it considers critical habitat to conflict with mission-essential 
training tasks, and that critical habitat designation would adversely 
affect Fort Hunter Liggett's training mission. The Army submitted a map 
to us of the mission-essential training areas that are found within 
lands we determined to be essential to the conservation of the arroyo 
toad (Army, in litt. 2003).
    The arroyo toad occupies an approximately 17-mi (27.4-km) segment 
of the San Antonio River at Fort Hunter Liggett. This arroyo toad 
population is essential to the conservation of the species because it 
is the northernmost known population--approximately 100 mi (160 km) 
north of the nearest documented extant population. Arroyo toads in this 
unit may experience climatic conditions not faced by toads at sites 
farther south. The protection of this area is essential to maintaining 
the complete genetic variability of the species and the full range of 
ecological settings within which it is found. This stretch of the San 
Antonio River is undammed, provides excellent habitat for the arroyo 
toad, and supports probably one of the largest populations within the 
Northern Region.
    The Army is currently consulting with us to finalize the 
development of an INRMP and associated Endangered Species Management 
Plan for the arroyo toad on Fort Hunter Liggett. The completion of 
these plans is projected to occur sometime in 2004. The Army recognizes 
the need for protection and conservation of sensitive species, 
including the arroyo toad, on military lands and has identified 
conservation measures to protect and conserve arroyo toads and their 
habitat. These plans include measures to minimize harm to the arroyo 
toad from training activities and outline actions to ensure the 
persistence of arroyo toads on the installation.
(1) Benefits of Inclusion
    The primary benefit of any critical habitat with regard to 
activities that require consultation pursuant to section 7 of the Act 
is to ensure that the activity will not destroy or adversely modify 
designated critical habitat. The educational benefits of critical 
habitat include informing the Army of areas that are important to the 
conservation of listed species. However, because the Army is already 
working cooperatively with the Service to develop an INRMP that 
protects the toad and its essential habitat on Fort Hunter Liggett and 
we will complete a Section 7 consultation on that plan, we do not 
believe that designation of mission-essential training areas on the 
fort will significantly benefit the arroyo toad beyond the protection 
already afforded the species under the Act. In addition, through the 
INRMP development process and development of a draft Endangered Species 
Management Plan for the arroyo toad, the Army is already aware of 
essential arroyo toad habitat areas on the installation.
(2) Benefits of Exclusion
    Substantial benefits are expected to result from the exclusion of 
mission-critical training areas on Fort Hunter Liggett from critical 
habitat. If we designate critical habitat within these areas, the Army 
would be required to engage in consultation with us on activities that 
may affect designated critical habitat. The requirement to consult on 
activities within mission-essential training areas could delay and 
impair the ability of the Army to conduct effective training activities 
and limit Fort Hunter Liggett's utility as a military training 
installation, thereby adversely affecting national security.
(3) Benefits of Exclusion Outweigh the Benefits of Inclusion
    We met with the Army on December 12, 2003, at Fort Hunter Liggett 
to discuss essential arroyo toad habitat, and possible impacts to the 
base. In light of national security interests and the Army's need to 
maintain a high level of readiness and fighting capabilities, we have 
considered, but have not proposed, critical habitat on lands identified 
by the Army as mission-essential training areas (Army, in litt. 2003). 
We find that the benefits of excluding these lands from critical 
habitat outweigh the benefits of including them. We further find that 
the exclusion of these areas will not lead to the extinction of the 
arroyo toad because Army training activities are conducted primarily 
outside of the floodplain and riparian corridor where toads are 
concentrated and are not expected to lead to the extirpation of the San 
Antonio River population. Although training activities have been 
conducted at the base since World War II, the arroyo toad population 
has persisted, and has possibly even improved over the past several 
years after grazing was terminated in 1991. The majority of the area on 
Fort Hunter Liggett that we identified as essential to the conservation 
of the species has not been excluded and is being proposed as critical 
habitat.
    Other developed areas that are integral to the mission of the Army, 
such as roads, tank trails, and river crossings, can be found within 
the boundary of proposed critical habitat at Fort Hunter Liggett. 
However, due to limitations inherent to using a 100 by 100-m grid cell 
size, we were not able to exclude these narrow, linear areas from the 
critical habitat proposal. However, established roads, river crossings, 
and tank trails at Fort Hunter Liggett do not contain the primary 
constituent elements, and their use and maintenance would not trigger a 
section 7 consultation with us on critical habitat.
    We are soliciting public review and comment on our decision to 
consider areas identified as essential, but not proposed as critical 
habitat for the arroyo toad, on mission-essential training areas at 
Camp Pendleton and Fort Hunter Liggett, and within the plan areas of 
the San Diego MSCP, Orange County Central-Coastal NCCP, Western 
Riverside MSHCP, and SDG&E NCCP/HCP based on section 4(b)(2) of the 
Act. Maps showing lands essential to the conservation of the arroyo 
toad, but excluded under the provisions of section 4(b)(2), are 
available for public review at either the Ventura or Carlsbad Fish and 
Wildlife Offices (see Addresses section or on the Internet at http://ventura.fws.gov or http://carlsbad.fws.gov. We will review this issue 
in light of all public comments received during the public review 
period and may reconsider our position in the final rule.

Economic Analysis

    Section 4(b)(2) of the Act requires us to designate critical 
habitat on the basis of the best scientific and commercial information 
available and to consider the economic and other relevant impacts of 
designating a particular area as critical habitat. We may exclude areas 
from critical habitat upon a determination that the benefits of such 
exclusions outweigh the benefits of specifying such areas as part of 
critical habitat. We cannot exclude such areas from critical habitat if 
such exclusion would result in the extinction of the species.
    An analysis of the economic impacts of proposing critical habitat 
for the

[[Page 23277]]

arroyo toad is being prepared. We will announce the availability of the 
draft economic analysis as soon as it is completed, at which time we 
will seek public review and comment. At that time, copies of the draft 
economic analysis will be available for downloading from the Internet 
at http://ventura.fws.gov, or from the Ventura Fish and Wildlife Office 
(see ADDRESSES section)

Peer Review

    In accordance with our joint policy published on July 1, 1994 (59 
FR 34270), we will solicit the expert opinions of at least three 
appropriate independent specialists regarding this proposed rule. The 
purpose of such review is to ensure that our critical habitat 
designation is based on scientifically sound data, assumptions, and 
analyses. We will send these peer reviewers copies of this proposed 
rule immediately following publication in the Federal Register. We will 
invite these peer reviewers to comment, during the public comment 
period, on the specific assumptions and conclusions regarding the 
proposed designation of critical habitat.
    We will consider all comments and information received during the 
comment period on this proposed rule as we prepare our final 
rulemaking. Accordingly, the final decision may differ from this 
proposal.

Clarity of the Rule

    Executive Order 12866 requires each agency to write regulations and 
notices that are easy to understand. We invite your comments on how to 
make this proposed rule easier to understand, including answers to 
questions such as the following: (1) Are the requirements in the 
proposed rule clearly stated? (2) Does the proposed rule contain 
technical jargon that interferes with the clarity? (3) Does the format 
of the proposed rule (grouping and order of the sections, use of 
headings, paragraphing, etc.) aid or reduce its clarity? (4) Is the 
description of the notice in the SUPPLEMENTARY INFORMATION section of 
the preamble helpful in understanding the proposed rule? (5) What else 
could we do to make this proposed rule easier to understand?
    Send a copy of any comments on how we could make this proposed rule 
easier to understand to: Office of Regulatory Affairs, Department of 
the Interior, Room 7229, 1849 C Street, NW., Washington, DC 20240. You 
may e-mail your comments to this address: [email protected].

Required Determinations

Regulatory Planning and Review

    This document has been reviewed by the Office of Management and 
Budget (OMB) in accordance with Executive Order 12866. OMB makes the 
final determination under Executive Order 12866. We are preparing a 
draft economic analysis of this proposed action, which will be 
available for public comment, to determine the economic consequences of 
designating specific areas as critical habitat. Within these areas, the 
types of Federal actions or authorized activities that we have 
identified as potential concerns are listed above in the section on 
Section 7 Consultation. The availability of the draft economic analysis 
will be announced in the Federal Register and in local newspapers so 
that it is available for public review and comment.

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 
(SBREFA) of 1996), 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 effects 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 
the agency certifies that the rule will not have a significant economic 
impact on a substantial number of small entities. The SBREFA amended 
the Regulatory Flexibility Act (RFA) to require Federal agencies to 
provide a statement of the factual basis for certifying that the rule 
will not have a significant economic impact on a substantial number of 
small entities. However, the SBREFA does not explicitly define 
``substantial number'' or ``significant economic impact.'' 
Consequently, to assess whether a ``substantial number'' of small 
entities is affected by this designation, this analysis considers the 
relative number of small entities likely to be affected in an area. The 
SBREFA also amended the RFA to require a certification statement.
    Our assessment of economic effect will be completed prior to final 
rulemaking and based upon review of the draft economic analysis 
prepared pursuant to section 4(b)(2) of the ESA and E.O. 12866. This 
analysis is for the purposes of compliance with the Regulatory 
Flexibility Act and does not reflect our position on the type of 
economic analysis required by New Mexico Cattle Growers Assn. v. U.S. 
Fish & Wildlife Service 248 F.3d 1277 (10th Cir. 2001).

Executive Order 13211

    On May 18, 2001, the President issued Executive Order 13211 on 
regulations that significantly affect energy supply, distribution, and 
use. Executive Order 13211 requires agencies to prepare Statements of 
Energy Effects when undertaking certain actions. This proposed rule to 
designate critical habitat for the arroyo toad is not expected to 
significantly affect energy supplies, distribution, or use. Therefore, 
this action is not a significant energy action and no Statement of 
Energy Effects is required.

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

    Under the Unfunded Mandates Reform Act (2 U.S.C. 1501 et seq.), if 
a rule will produce a Federal mandate of $100 million or greater in any 
one year, a statement must be prepared and a summary of that statement 
included in the rulemaking. In general, a Federal mandate is a 
provision in legislation, statute or regulation that would impose an 
enforceable duty upon State, local, 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). If the economic analysis being prepared to analyze 
the economic impacts of this designation indicates that the rule will 
produce a Federal mandate of $100 million or more in any year, a 
statement will be prepared and this proposed rule will be supplemented 
with a summary of that statement published in the notice announcing 
availability of the proposed economic analysis.
    This proposed rule will not ``significantly or uniquely'' affect 
small governments. A Small Government Agency Plan is not required. 
State lands constitute a very small amount, only 0.7%, of the total 
proposed designation. Given the distribution of this species, small 
governments will not be uniquely affected by this proposed rule. Small 
governments will not be affected at all unless they propose an action 
requiring Federal funds, permits, or other authorization. Any such 
activity will require that the involved Federal agency ensure that the 
action is not likely to adversely modify or destroy designated critical 
habitat. However, as discussed above, Federal agencies are currently 
required to ensure that any such activity

[[Page 23278]]

is not likely to jeopardize the species, and no further regulatory 
impacts from this proposed designation of critical habitat are 
anticipated. We will examine any potential impacts to small governments 
in our economic analysis, and revise our determination if necessary.

Takings

    In accordance with Executive Order 12630 (``Government Actions and 
Interference with Constitutionally Protected Private Property 
Rights''), we have analyzed the potential takings implications of 
designating critical habitat for the arroyo toad. The takings 
implication assessment concludes that this proposed rule does not pose 
significant takings implications.

Federalism

    In accordance with Executive Order 13132, the rule does not have 
significant Federalism effects. A Federalism assessment is not 
required. In keeping with the Department of Interior policies, we 
requested information from, and coordinated development of, this 
proposed critical habitat designation with appropriate State resource 
agencies in California. The proposed designation of critical habitat in 
areas currently occupied by the arroyo toad imposes no additional 
restrictions to those currently in place and, therefore, has little 
incremental impact on State and local governments and their activities. 
The proposed designation may have some benefit to the States and local 
resource agencies in that the areas essential to the conservation of 
the species are more clearly defined, and the primary constituent 
elements of the habitat necessary to the survival of the species are 
specifically identified. While making this definition and 
identification does not alter where and what federally sponsored 
activities may occur, it may assist local governments in long-range 
planning (rather than waiting for case-by-case section 7 consultations 
to occur).

Civil Justice Reform

    In accordance with Executive Order 12988, the Department of the 
Interior's Office of the Solicitor has 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 proposing to designate 
critical habitat in accordance with the provisions of the Endangered 
Species Act. This proposed 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 arroyo 
toad.

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

    This proposed rule does not contain new or revised information 
collection for which OMB approval is required under the Paperwork 
Reduction Act. 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.

National Environmental Policy Act

    We have determined that we do not need to prepare an Environmental 
Assessment and/or an Environmental Impact Statement as defined by the 
National Environmental Policy Act of 1969 in connection with 
regulations adopted pursuant to section 4(a) of the Act. We published a 
notice outlining our reasons for this determination in the Federal 
Register on October 25, 1983 (48 FR 49244). This final determination 
does not constitute a major Federal action significantly affecting the 
quality of the human environment.

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), Executive Order 13175, and the Department 
of the Interior's manual at 512 DM 2, we have coordinated with 
federally recognized Tribes on a Government-to-Government basis. We 
have determined that certain Tribal lands are essential for the 
conservation of the arroyo toad because they support essential 
populations and habitat, and activities conducted or planned on those 
lands may adversely affect the conservation of the arroyo toad. 
Therefore, we are proposing to designate critical habitat for the 
arroyo toad on some Tribal lands. Information relative to each 
reservation is included in the critical habitat unit descriptions. We 
have excluded some areas from proposed critical habitat upon a 
determination that the lands did not meet the criteria for critical 
habitat.

Relationship to Mexico

    We are not aware of any existing national regulatory mechanism in 
Mexico that would protect the arroyo toad or its habitat. Although new 
legislation for wildlife is pending in Mexico and Mexico has laws that 
could provide protection for rare species, there are enforcement 
challenges. Even if specific protections were available and enforceable 
in Mexico, the portion of the arroyo toad's range in Mexico alone, in 
isolation, would not be adequate to ensure the long-term conservation 
of the species.

ARROYO TOAD (Bufo californicus)
    (1) Critical habitat units are depicted for Monterey, Santa 
Barbara, Ventura, Los Angeles, San Bernardino, Riverside, Orange, and 
San Diego Counties, CA, on the maps below.
    (2) Critical habitat consists of stream and river courses, riparian 
habitats, and adjacent terrace and upland habitats.
    (3) Within these areas, the primary constituent elements of the 
arroyo toad include:
    (i) Rivers or streams with hydrologic regimes that supply water to 
provide space, food, and cover needed to sustain eggs, tadpoles, 
metamorphosing juveniles, and adult breeding toads. Specifically, the 
conditions necessary to allow for successful breeding of arroyo toads 
are:
    (A) Breeding pools with areas less than 12 in (30 cm) deep;
    (B) Areas of flowing water with current velocities less than 1.3 ft 
per second (40 cm per second); and
    (C) Surface water that lasts for a minimum length of 2 months in 
most years, i.e., a sufficient wet period in the spring months to allow 
arroyo toad larvae to hatch, mature, and metamorphose.
    (ii) Low-gradient stream segments (typically less than 6 percent) 
with sandy or fine gravel substrates that support the formation of 
shallow pools and sparsely vegetated sand and gravel bars for breeding 
and rearing of tadpoles and juveniles.
    (iii) A natural flooding regime or one sufficiently corresponding 
to a natural regime that will periodically scour riparian vegetation, 
rework stream channels and terraces, and redistribute sands and 
sediments, such that breeding pools and terrace habitats with scattered 
vegetation are maintained.
    (iv) Riparian and adjacent upland habitats (particularly alluvial 
streamside terraces and adjacent valley bottomlands that include areas 
of loose soil where toads can burrow underground) to provide foraging 
and living areas for subadult and adult arroyo toads.
    (v) Stream channels and adjacent upland habitats that allow for 
migration to foraging areas, overwintering sites, dispersal between 
populations, and recolonization of areas that contain suitable habitat.
    (4) Critical habitat does not include man-made 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, roads, and the land on which such structures are located.
    (5) Index maps of arroyo toad proposed critical habitat follow.
