Endangered and Threatened Wildlife and Plants; Designation of 
Critical Habitat for the California Tiger Salamander, Central 
Population

AGENCY: Fish and Wildlife Service, Interior.

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: We, the U.S. Fish and Wildlife Service (Service), propose to 
designate critical habitat for the California tiger salamander 
(Ambystoma californiense) (referred to hereafter as the CTS) pursuant 
to the Endangered Species Act of 1973, as amended (Act). This rule 
contains the proposal for the Central California population of the CTS 
(hereafter referred to as the Central population). Approximately 
382,666 acres (ac) (154,860 hectares (ha)) occur within the boundaries 
of the proposal for the Central population.

SUPPLEMENTARY INFORMATION:

Executive Summary

    The proposed critical habitat is in the following 20 counties in 
central California: Alameda, Amador, Calaveras, Contra Costa, Fresno, 
Kern, Kings, Madera, Mariposa, Merced, Monterey, Sacramento, San 
Benito, San Joaquin, San Luis Obispo, Santa Clara, Solano, Stanislaus, 
Tulare, and Yolo. This proposed designation does not include critical 
habitat for the Santa Barbara County or Sonoma County areas. A proposed 
rule to designate critical habitat for the Santa Barbara County 
population was published on January 22, 2004 (69 FR 3064). We are not 
proposing to designate critical habitat for the Sonoma County 
geographic area of the California tiger salamander at this time. We are 
currently in the process of developing a management strategy for the 
Sonoma County area for the California tiger salamander and other listed 
and sensitive species. The planning efforts include various local, 
State and Federal agencies including ourselves, the U.S. Army Corps of 
Engineers, the California Department of Fish and Game, the County of 
Sonoma, the cities of Santa Rosa, Rohnert Park, and Cotati, and local 
and regional environmental organizations. The group is developing a 
management and restoration plan as well as identifying areas for 
conservation of the vernal pool and other California tiger salamander 
habitat within the area.
    We expect the plan, when complete, to provide a better means of 
identifying essential habitat than our critical habitat designation 
process can provide at the present time. By bringing together all 
local, State, and Federal species experts and local planning officials 
we are better able to identify areas which are essential for the 
conservation of the California tiger salamander in Sonoma County. The 
management planning process is a collaborative effort involving 
cooperation and input from numerous stakeholders such as landowners, 
public land managers, and the general public. This allows the best 
information and local knowledge to be brought to the table, and may 
encourage a sense of commitment to the California tiger salamander's 
continued well being in the area. Due to time constraints we are unable 
to match this level of public participation in the critical habitat 
designation process. We believe that currently designating proposed 
critical habitat would cause more harm to the species by causing delays 
to and confusing the current ongoing process. The enhancement and 
management of California tiger salamander habitat will benefit greatly 
from coordination between the various land owners and managers in the 
area. The ongoing planning process can provide for that coordination, 
whereas the critical habitat designation process may not. Once the 
planning efforts have identified areas essential for the California 
tiger salamander, we will consider proposing critical habitat at that 
time. Should these planning efforts fail to identify essential areas 
for the California tiger salamander we will issue a notice to propose 
additional critical habitat for the species.
    Critical habitat identifies specific areas, both occupied and 
unoccupied by a listed species, which are essential to the conservation 
of the species and that may require special management considerations 
or protection. The primary constituent elements for the California 
tiger salamander are aquatic and upland areas, including vernal pool 
complexes, where suitable breeding and nonbreeding habitats are 
interspersed throughout the landscape, and are interconnected by 
continuous dispersal habitat. All areas proposed for designation as 
critical habitat for the Central population contain one or more of the 
primary constituent elements.

[[Page 48571]]

    Section 4 of the Act requires us to consider economic and other 
relevant impacts of specifying any particular area as critical habitat. 
Section 7 of the Act prohibits destruction or adverse modification of 
critical habitat by any activity funded, authorized, or carried out by 
any Federal agency. We solicit data and comments from the public on all 
aspects of this proposal, including data on the economic and other 
impacts of designation. We may revise this proposal to incorporate or 
address new information received during the comment period.

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 parties 
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 
California tiger salamander 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 
subject areas and their possible impacts on proposed critical habitat;
    (4) Any foreseeable economic or other potential impacts resulting 
from the proposed designation and, in particular, any impacts on small 
entities;
    (5) 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;
    (6) Specific information from present landowners regarding the 
current extent and quality of extant occurrences and breeding habitats 
found within the proposed designated geographic areas and units;
    (7) Whether or not private landowners are willing to enter into 
partnerships or conservation agreements with us for the benefit of the 
California tiger salamander and its habitats;
    (8) Whether or not we should enter into conservation agreements or 
partnerships with private landowners for the conservation of the 
California tiger salamander and its habitats and, upon successful 
implementation of these agreements, if we should remove these areas 
from critical habitat; and
    (9) Appropriateness of excluding any proposed areas, such as 
portions of the former Fort Ord for which an HCP is currently being 
developed.
    If you wish to comment, you may submit your comments and materials 
concerning this proposal by any one of several methods (see ADDRESSES 
section). 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 addresses 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 (see ADDRESSES 
section).

Designation of Critical Habitat Provides Little Additional Protection 
to the Species

    In 30 years of implementing the Act, the Service has found that the 
designation of statutory critical habitat provides little additional 
protection to most listed species, while consuming significant amounts 
of available conservation resources. The Service's 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. 
The Service believes 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 Act 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 the jurisdiction of the 
Service 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. The Service believes 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 the Service 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 the 
Service with little ability to prioritize its 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, to respond to 
Notices of Intent (NOIs) to sue relative to critical habitat, and to 
comply with the growing number of adverse court orders. As a result of 
this consequence, listing petition responses, the Service's own 
proposals to list critically imperiled species, and final listing 
determinations on existing proposals are all significantly delayed.
    The accelerated schedules of court ordered designations have left 
the Service with almost little ability to provide for adequate public

[[Page 48572]]

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 situation 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.
    The costs resulting from the designation include legal costs, the 
costs of preparation and publication of the designation, the analysis 
of the economic effects and the costs of requesting and responding to 
public comments, and, in some cases, the costs of compliance with 
National Environmental Policy Act, represent the costs of critical 
habitat designation. None of these costs result in any benefit to the 
species that is not already afforded by the protections of the Act 
enumerated earlier, and theses associated costs directly reduce the 
scarce funds available for direct and tangible conservation actions.

Background

    A physical description of the CTS, and other information about its 
taxonomy, distribution, life history, and biology is included in the 
Background section of the final rule to list California tiger 
salamander as a threatened species, published in the Federal Register 
earlier. Additional relevant information may be found in the final 
rules to list the Santa Barbara County DPS (65 FR 57242, September 21, 
2000) and the Sonoma County DPS CTS (68 FR 13498, March 13, 2003), and 
the January 22, 2004, proposal to designate critical habitat for the 
Santa Barbara population (69 FR 3064).

Habitat Requirements and Characteristics

    The CTS inhabits, in Central California, low-elevation (typically 
below 1,500 feet (ft) (460 m)), vernal pools, vernal pool complexes, 
and seasonal ponds in associated annual grasslands, oak savannah, and 
coastal scrub plant communities of the Bay Area (Santa Clara Valley), 
Central Coast, Central Valley, and Southern San Joaquin Valley (Shaffer 
et al. 1993; Service 2000; Service 2003).
    CTS are found in seasonal ponds, natural vernal pools, vernal pool 
complexes, and small artificial water bodies such as stockponds for 
breeding during their aquatic phase (Stebbins 1985; Zeiner et al. 1988; 
Shaffer et al. 1993). However, stockponds often are not optimum aquatic 
breeding habitat for California tiger salamanders because stockponds 
may not hold water long enough for completion of part of their life 
cycle. Hydroperiods may be so short that larvae cannot metamorphose 
(e.g., early drawdown of irrigation ponds), or so long that predatory 
fish and bullfrogs (Rana catesbeiana) can colonize the pond (Shaffer et 
al. 1993; Seymour and Westphal 1994). Permanent wetlands can support 
breeding California tiger salamanders if fish are not present, but 
extirpation of the salamander occurrence is likely if fish are 
introduced (Shaffer et al. 1993; Seymour and Westphal 1994). Artificial 
ponds also require ongoing maintenance and are often temporary 
structures. Periodic maintenance to remove silt from stockponds or to 
reinforce or strengthen berms may also cause a temporary loss of 
functioning aquatic habitat. Regardless of vernal pool, pond, or 
seasonal wetland type, successful breeding ponds for California tiger 
salamanders need to be inundated (hold water) for a minimum of 12 weeks 
to allow for successful metamorphosis.
    The aquatic component of the Central population habitat consists of 
temporary ponded freshwater habitats. Historically, the vernal pools 
and vernal pool complexes constituted the majority of California tiger 
salamander breeding habitat. Vernal pools typically form in topographic 
depressions underlain by an impervious layer (such as claypan, hardpan, 
or volcanic layer) that prevents downward percolation of water, and 
they occur as groups of pools referred to as vernal pool complexes. 
Vernal pool hydrology is characterized by ponding of water during the 
late fall, winter, and spring, followed by complete desiccation (drying 
out) during the summer dry season (Holland and Jain 1998).
    California tiger salamanders spend the majority of their lives in 
upland habitats. The upland component of Central population habitat 
typically consists of vernal pool grassland or grassland savannah with 
scattered oak trees. However, some occupied California tiger salamander 
breeding ponds exist within mixed grassland and woodland habitats, in 
woodlands, scrub, or chaparral habitats.
    Within these upland habitats, adult California tiger salamanders 
spend part of their lives in the underground burrows of small mammals, 
especially the burrows of California ground squirrels (Spermophilus 
beecheyi) and valley pocket gophers (Thomomys bottae) (Barry and 
Shaffer 1994), at depths ranging from 20 cm (8.0 in) to 1 m (3.3 ft) 
beneath the ground surface (Trenham 2001). These burrows provide food 
for California tiger salamanders, as well as protection from the sun 
and wind associated with the dry California climate that can cause 
desiccation of amphibian skin. Although California tiger salamanders 
are members of a family of burrowing salamanders, California tiger 
salamanders are not known to create their own burrows in the wild and 
require small mammal burrows for survival. Because they live 
underground in the burrows of mammals, they are rarely encountered even 
where abundant.

Dispersal and Migration

    Movements made by California tiger salamanders can be grouped into 
two main categories: (1) Breeding migration, and (2) interpond 
dispersal. Breeding migration is the movement of salamanders to and 
from a pond from the surrounding upland habitat. After metamorphosis, 
juveniles move away from breeding ponds into the surrounding uplands, 
where they live continuously for several years (on average, 4 years). 
Upon reaching sexual maturity, most individuals return to their natal 
(birth) pond to breed, while 20 percent disperse to other ponds 
(Trenham et al. 2001). Following breeding, adult California tiger 
salamanders return to upland habitats, where they may live for one or 
more years before breeding again (Trenham et al. 2000).
    Data suggest that juvenile California tiger salamanders disperse 
further into upland habitats than adult California tiger salamanders. A 
trapping study conducted in Solano County during winter 2002-03 found 
that juveniles used upland habitats further from breeding ponds than 
adults (Trenham and Shaffer, in review). More juvenile salamanders were 
captured at distances of 300, 600, and 1,300 ft (100, 200, and 400 m), 
respectively, from a breeding pond than at 160 ft (50 m). Large numbers 
(approximately 20 percent of total captures) were found 1,300 ft (400 
m) from a breeding pond. Fitting a distribution curve to the data 
revealed that 95 percent of juvenile salamanders could be found within 
2,000 ft (640 m) of the pond, with the remaining 5 percent being found 
at even greater distances.
    Post-breeding movements away from breeding ponds by adults appear 
to be much smaller. During post-breeding emigration, radio-equipped 
adult California tiger salamanders were tracked to burrows 62 to 813 ft 
(19 to 248 m) from their breeding ponds

[[Page 48573]]

(Trenham 2001). These reduced movements may be due to adult California 
tiger salamanders having depleted physical reserves post-breeding, or 
also due to the drier weather conditions that are typical of the period 
when adults leave the ponds.
    The spatial distribution of California tiger salamanders in the 
uplands surrounding aquatic habitats or breeding ponds is a key issue 
for protection of upland and breeding habitat and essential 
conservation planning. Although it might be supposed that California 
tiger salamanders will move only short distances if abundant burrows 
are found near their ponds, this is not the case. In the aforementioned 
study in Solano County, while abundant burrows are available near the 
pond, a nearly equal number of California tiger salamanders were 
captured at 300, 600, and 1,300 ft (100, 200 and 400 m), respectively, 
from the breeding pond (Trenham and Shaffer, in review). Similarly, 
Trenham (2001) tracked salamanders to burrows up to 800 ft (248 m) from 
a breeding pond, although burrows were abundant at distances nearer to 
the pond. In addition, rather than staying in a single burrow, most 
individuals used several successive burrows at increasing distances 
from the pond.
    Documented dispersers had moved up to 2,200 ft (670 m), and, based 
on a projected exponential relationship between dispersal probability 
and distance, less than 1 percent of dispersers are likely to move 
between ponds separated by 0.70 mile (mi) (1,160 m) (Trenham et al. 
2001). The frequency of dispersal among known extant occurrences or 
subpopulations will ultimately depend on the distance between the ponds 
or complexes and also on the intervening habitat (e.g., salamanders may 
move more quickly through grassland than through more densely vegetated 
scrublands).
    Although the studies discussed above provide an approximation of 
the distances that California tiger salamanders regularly move from 
their breeding ponds, upland habitat features influence movements in a 
particular landscape. Unlike other ambystomatid salamanders, California 
tiger salamanders and other tiger salamanders are grassland animals and 
do not favor forested areas as corridors for movement or long-term 
residence. Trenham (2001) found that radio-tracked adults favored 
grasslands with scattered large oaks over more densely wooded areas. 
Based on radio-tracked adults, there is no indication that California 
tiger salamanders favor certain habitat types as corridors for 
terrestrial movements (Trenham 2001).

Previous Federal Actions

    For a discussion of previous Federal actions regarding the Central 
population, please see the final rule to list the Central California 
Distinct Population Segment of the California tiger salamander as 
threatened across its range. Federal actions on the CTS prior to May 
2004 are summarized in that final rule, published in a recent Federal 
Register, and are incorporated by reference.

Critical Habitat

    Critical habitat is defined in section 3(5)(A) of the Act as: (i) 
The specific areas within the geographic area occupied by a species, at 
the time it is listed in accordance with the Act, on which are found 
those physical or biological features (I) essential to the conservation 
of the species and (II) that may require special management 
considerations or protection; and (ii) specific areas outside the 
geographic area occupied by a species at the time it is listed, upon a 
determination that such areas are essential for the conservation of the 
species. ``Conservation'' means the use of all methods and procedures 
that are necessary to bring an endangered or a threatened species to 
the point at which listing under the Act is no longer necessary.
    The designation of critical habitat does not affect land ownership 
or establish a refuge, wilderness, reserve, preserve, or other 
conservation area. It does not allow government or public access to 
private lands. Critical habitat receives protection under section 7 of 
the Act through the prohibition against destruction or adverse 
modification of critical habitat with regard to actions carried out, 
funded, or authorized by a Federal agency. Section 7 requires 
consultation on Federal actions that may adversely affect critical 
habitat, and conferences on Federal actions that are likely to result 
in the destruction or adverse modification of 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.'' Aside from the added protection that may be provided 
under section 7, the Act does not provide other forms of protection to 
lands designated as critical habitat. Because consultation under 
section 7 of the Act does not apply to activities on private or other 
nonfederal lands that do not involve a Federal nexus, critical habitat 
designation would not afford any additional protections under the Act 
against such activities.
    To be included in a critical habitat designation, the habitat must 
first be ``essential to the conservation of the species.'' Critical 
habitat designations identify, to the extent known using the best 
scientific and commercial data available, habitat areas that provide 
essential physical and biological features (i.e., areas on which are 
found the primary constituent elements, as defined at 50 CFR 424.12(b)) 
and which may require special management considerations or protections, 
or be specific areas outside of the geographic areas occupied by the 
species which are determined to be essential to the conservation of the 
species. Section 3(5)(C) of the Act states that not all areas that can 
be occupied by a species should be designated as critical habitat 
unless the Secretary determines that all such areas are essential to 
the conservation of the species. Regulations at 50 CFR 424.02(j) define 
special management considerations or protection to mean any methods or 
procedures useful in protecting the physical and biological features of 
the environment for the conservation of listed species.
    When we designate critical habitat, we may not have the information 
necessary to identify all areas that are essential for the conservation 
of the species. Nevertheless, we are required to designate those areas 
we consider to be essential, using the best information available to 
us. Accordingly, we do not designate critical habitat in areas outside 
the geographic area occupied by the species unless the best scientific 
and commercial data demonstrate that unoccupied areas are essential for 
the conservation needs of the species.
    Within the geographic areas occupied by the species, we will 
designate only areas currently known to be essential. Essential areas 
should already have the features and habitat characteristics that are 
necessary to sustain the species. We will not speculate about what 
areas might be found to be essential if better information became 
available, or what areas may become essential over time. If the 
information available at the time of designation does not show that an 
area is essential to the conservation of a species, then the area 
should not be included in the critical habitat designation. We will not 
designate areas

[[Page 48574]]

that do not now have the primary constituent elements, as defined at 50 
CFR 424.12(b). We have excluded from this proposal some areas where CTS 
are currently found, areas of suitable habitat where they might 
potentially occur, some localities where they historically occurred, 
and areas that do not have one or more of the primary constituent 
elements. Only areas considered essential to the conservation of the 
species are included in this proposal.
    Section 4(b)(2) of the Act requires that we take into consideration 
the economic impact, and any other relevant impact, including impacts 
to National security, of specifying any particular area as critical 
habitat. We may exclude areas from critical habitat designation when 
the benefits of exclusion outweigh the benefits of including the areas 
within critical habitat, provided the exclusion will not result in 
extinction of the species.
    Our Policy on Information Standards Under the Endangered Species 
Act, published in the Federal Register on July 1, 1994 (59 FR 34271), 
provides criteria, establishes procedures, and provides guidance to 
ensure that decisions made by the Service represent the best scientific 
and commercial data available. Our policy requires Service biologists, 
to the extent consistent with the Act and with the use of the best 
scientific and commercial data available, to use primary and original 
sources of information as the basis for recommendations to designate 
critical habitat. When determining areas are critical habitat, a 
primary source of information should be the listing package for the 
species. Additional information may be obtained from a recovery plan, 
articles in peer-reviewed journals, conservation plans developed by 
States and counties, scientific status surveys and studies, biological 
assessments, unpublished materials, and expert opinion or personal 
knowledge.
    We recognize that the proposed designation of critical habitat does 
not include all of the occupied habitat areas that may eventually be 
determined to be essential for the conservation of the species. For 
these reasons, everyone should understand that critical habitat 
designations do not signal that habitats outside the designation are 
unimportant to California tiger salamanders. Areas outside the critical 
habitat designation will continue to be subject to conservation actions 
that may be implemented under section 7(a)(1), and to the regulatory 
protections afforded by the section 7(a)(2) jeopardy standard and the 
section 9 take prohibition, as determined on the basis of the best 
available information at the time of the action. We specifically 
anticipate that federally funded or assisted projects affecting listed 
species outside their designated critical habitat areas may still 
result in jeopardy findings in some cases. Similarly, critical habitat 
designations made on the basis of the best available information at the 
time of designation will not control the direction and substance of 
future recovery plans, habitat conservation plans, or other species 
conservation planning efforts if new information available to these 
planning efforts calls for a different outcome.

Methods

    In determining areas that are essential to conserve the Central 
population, we used the best scientific and commercial data available. 
We have reviewed the overall approach to the conservation of the 
California tiger salamander undertaken by local, State, and Federal 
agencies operating within the species' range since its proposed listing 
in 2003 (68 FR 28648). We have also reviewed available information that 
pertains to the upland and aquatic habitat requirements of this 
species. In our designation, we included only areas within which the 
best available information indicates the species currently occurs. We 
identified proposed critical habitat units that we thought had the 
highest likelihood to be self-sustaining on the basis of density of CTS 
occurrences, and kind, amount, and quality of habitat associated with 
those occurrences. The proposed units represent the range of 
environmental, ecological, and genetic variation of the CTS and contain 
the primary constituent elements we have determined are essential to 
the conservation of the species.
    The extant occurrences within proposed units total approximately 68 
percent of extant occurrences within the range of the species. These 
extant occurrences include observations from CNDDB (2003), data in 
reports submitted during section 7 consultations, data from biologists 
holding section 10(a)(1)(A) recovery permits; research published in 
peer-reviewed articles and presented in academic theses and agency 
reports, and regional Geographic Information System (GIS) coverages.
    The proposed critical habitat units were delineated by creating 
approximate areas for the units by screen digitizing polygons (map 
units) using ArcView (Environmental Systems Research Institute, Inc.), 
a computer GIS program. The polygons were created by overlaying extant 
California tiger salamander location points with 0.7 mile buffers 
(CNDDB 2003) (see Criteria section below), and mapped vernal pool 
grassland habitats (Holland 1998a, 2003), or other vernal pool or 
grassland location information, onto SPOT imagery (satellite aerial 
photography).
    We evaluated the resulting shape files (delineating historic 
geographic range and potential suitable habitat), refined elevation and 
hydrologic ranges, and identified areas of non-essential habitat (i.e., 
not containing the primary constituent elements) (see Primary 
Constituent Elements section). We excluded areas that do not contain 
one or more of the primary constituent elements or were not found to be 
essential for the conservation of the species because: (1) The area is 
highly degraded and may not be restorable; (2) the area is small, 
highly fragmented, or isolated and may provide little or no long-term 
conservation value; and (3) other areas within the geographic region 
were determined to be sufficient to meet the conservation needs of the 
species.

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 propose as critical 
habitat, we are required to base critical habitat determinations on the 
best scientific and commercial data available and to consider those 
physical and biological features (primary constituent elements (PCEs)) 
that are essential to the conservation of the species, and that may 
require special management considerations and protection. These 
include, but are not limited to; space for individual and population 
growth and for normal behavior; food, water, air, light, minerals, or 
other nutritional or physiological requirements; cover or shelter; 
sites for breeding, reproduction, and rearing (or development) of 
offspring; and habitats that are protected from disturbance or are 
representative of the historic geographical and ecological 
distributions of a species.
    All areas proposed as critical habitat for the Central population 
are within the species' historic range and contain one or more of the 
physical or biological features (primary constituent elements) 
identified as essential for the conservation of the species. Critical 
habitat for Central population includes essential aquatic habitat, 
essential upland nonbreeding habitat with underground refugia, 
dispersal habitat connecting occupied California tiger salamander 
locations to each other, and vernal pool complexes where integrated 
function of uplands and wetlands provide physical and biological 
features

[[Page 48575]]

essential to the conservation of the species. In addition, the critical 
habitat we have proposed is designed to conserve the distinct genetic 
structure of the Central population and allow for an increase in the 
size of salamander populations, both of which are essential to the 
conservation of the species. Special management, such as habitat 
rehabilitation efforts (e.g., removal of nonnative predators, control 
of introduced tiger salamanders, and erosion and sediment control 
measures), may be necessary throughout the areas being proposed.
    Based on our current knowledge of the life history, biology, and 
ecology of the species and the relationship of its essential life 
history functions to its habitat, as summarized above (see Background 
section), we have determined that the CTS requires the following 
primary constituent elements:
    (1) Standing bodies of fresh water, including natural and man-made 
(e.g., stock) ponds, vernal pools, and other ephemeral or permanent 
water bodies that typically become inundated during winter rains and 
hold water for a sufficient length of time necessary for the species to 
complete the aquatic portion of its life cycle.
    (2) Barrier-free upland habitats adjacent to breeding ponds that 
contain small mammal burrows, including but not limited to burrows 
created by the California ground squirrel and valley pocket gopher. 
Small mammals are essential in creating the underground habitat that 
adult California tiger salamanders depend upon for food, shelter, and 
protection from the elements and predation.
    (3) Upland areas between occupied locations (PCE 1) and areas with 
small mammal burrows (PCE 2) that allow for dispersal among such sites.
    (4) The geographic, topographic, and edaphic features that support 
aggregations or systems of hydrologically interconnected pools, swales, 
and other ephemeral wetlands and depressions within a matrix of 
surrounding uplands, which together form hydrologically and 
ecologically functional units called vernal pool complexes. These 
features contribute to the filling and drying of the vernal pool, 
maintain suitable periods of pool inundation for larval salamanders and 
their food sources, and provide breeding, feeding, and sheltering 
habitat for juvenile and adult salamanders and small mammals that 
create burrow systems essential for CTS estivation.
    We describe the relationship between each of these PCEs and the 
conservation of the salamander in more detail below.
    The essential aquatic habitat described as the first PCE is 
essential for Central population breeding and for providing space, 
food, and cover necessary to sustain early life history stages of 
larval and juvenile CTS. Breeding habitat consists of fresh water 
bodies, including natural and man-made ponds (e.g., stockponds), and 
vernal pools. To be considered essential, aquatic and breeding habitats 
must have the capability to hold water for a minimum of 12 weeks in the 
winter or spring in a year of average rainfall because this is the 
amount of time needed for larvae to grow into metamorphosed juveniles 
so they can become capable of surviving in upland habitats. During 
periods of drought or less-than-average rainfall, these sites may not 
hold water long enough for individuals to complete metamorphosis, 
however, these sites would still be considered essential because they 
constitute breeding habitat in years of average rainfall. Without its 
essential aquatic and breeding habitats, the Central population would 
not survive, reproduce, develop juveniles, and grow into adult 
individual salamanders that can complete their life cycles.
    Essential upland habitats containing underground refugia described 
as the second PCE are essential for the survival of adult and juvenile 
salamanders that have recently undergone metamorphosis. Adult and 
juvenile California tiger salamanders are primarily terrestrial. Adult 
California tiger salamanders enter aquatic habitats only for relatively 
short periods of time to breed. For the majority of their life cycle, 
California tiger salamanders depend for survival on upland habitats 
containing underground refugia in the form of small mammal burrows. 
California tiger salamanders cannot persist without upland underground 
refugia. These underground refugia provide protection from the hot, dry 
weather typical of California in the nonbreeding season. California 
tiger salamanders also find food in small mammal burrows and rely on 
the burrows for protection from predators. The presence of small 
burrowing mammal populations is essential for constructing and 
maintaining burrows. Without the continuing presence of small mammal 
burrows in upland habitats, California tiger salamanders would not be 
able to survive.
    Essential dispersal habitats generally consist of upland areas 
adjacent to essential aquatic habitats which are not isolated from 
essential aquatic habitats by barriers that California tiger 
salamanders cannot cross. Essential dispersal habitats provide 
connectivity among CTS suitable aquatic and upland habitats. While CTS 
can bypass many obstacles, and do not require a particular type of 
habitat for dispersal, the habitats connecting essential aquatic and 
upland habitats need to be free of barriers (e.g., a physical or 
biological feature that prevents salamanders from dispersing beyond the 
feature) to function effectively. Examples of barriers are areas of 
steep topography devoid of soil or vegetation. Agricultural lands such 
as row crops, orchards, vineyards, and pastures do not constitute 
barriers to the dispersal of California tiger salamanders. In general, 
we propose critical habitat that allows for dispersal between extant 
occurrences within 0.7 mi (1.13 km) of each other. To provide for 
conservation of the species, we choose 0.7 mi because that distance 
provides for 99 percent of the chances that individual salamanders can 
move and breed between extant occurrences, and, thereby, provides for 
genetic exchange between individuals within each region.
    The dispersal habitats described as the third PCE are essential for 
the conservation of the CTS. Protecting the ability of California tiger 
salamanders to move freely across the landscape in search of suitable 
aquatic and upland habitats is essential in maintaining gene flow and 
for recolonization of sites that may become temporarily extirpated. 
Lifetime reproductive success for the CTS and other tiger salamanders 
is naturally low. Trenham et al. (2000) found the average female bred 
1.4 times and produced 8.5 young that survived to metamorphosis per 
reproductive effort. This reproduction resulted in roughly 11 
metamorphic offspring over the lifetime of a female. In part, this low 
reproductive success is due to the extended time it takes for 
California tiger salamanders to reach sexual maturity; most do not 
breed until 4 or 5 years of age. While individuals may survive for more 
than 10 years, many breed only once. Combined with low survivorship of 
metamorphosed individuals (in some populations, fewer than 5 percent of 
marked juveniles survive to become breeding adults (Trenham et al. 
2000)), reproductive output in most years is not sufficient to maintain 
populations. This trend suggests that the species requires occasional 
large breeding events to prevent extirpation (temporary or permanent 
loss of the species from a particular habitat) or extinction (Trenham 
et al. 2000). With such low recruitment, isolated populations are 
susceptible to unusual, randomly occurring natural events as well as 
from

[[Page 48576]]

human-caused factors that reduce breeding success and individual 
survival. Factors that repeatedly lower breeding success in isolated 
vernal pools or ponds can quickly extirpate an occurrence of the 
species. Therefore, an essential element for successful conservation is 
the presence and maintenance of sets of interconnected sites that are 
within the ``rescue'' distance of other ponds (Trenham et al. 2001).
    Dispersal habitats described as the third PCE are also essential in 
preserving the population structure of the CTS. The life history and 
ecology of the California tiger salamander make it likely that this 
species has a metapopulation structure (Hanski and Gilpin 1991). A 
metapopulation is a set of breeding sites within an area, where typical 
migration from one local occurrence or breeding site to other areas 
containing suitable habitat is possible, but not routine. Movement 
between areas containing suitable upland and aquatic habitats (i.e., 
dispersal) is restricted due to inhospitable conditions around and 
between areas of suitable habitats. Because many of the areas of 
suitable habitats may be small and support small numbers of 
salamanders, local extinction of these small units may be common. The 
persistence of a metapopulation depends on the combined dynamics of 
these local extinctions and the subsequent recolonization of these 
areas through dispersal (Hanski and Gilpin 1991; Hanski 1994).
    Vernal pool complexes addressed in the fourth PCE provide a 
significant amount of the habitat for Central population remaining in 
the southern San Joaquin and Central Valley regions, but less so in the 
Bay Area and Coast Range regions because so much vernal pool habitat 
has been converted to other land uses. Vernal pools and other natural 
seasonal ponds are the primary historic breeding sites used by 
California tiger salamanders (Storer 1925; Feaver 1971; Zeiner et al. 
1988; Trenham et al. 2000). Historically, the species occurs in 10 of 
the 17 California vernal pool regions defined by Keeler-Wolf et al. 
(1998), including northeastern Sacramento Valley, southeastern 
Sacramento Valley, Santa Rosa, Solano-Colusa, Livermore, Central Coast, 
Carrizo, southern Sierra Foothills, Santa Barbara, and San Joaquin 
Valley. Only in historic times have man-made stock ponds joined or, in 
some areas, replaced vernal pools as breeding habitat. We have included 
vernal pool complexes as a PCE because they represent a landscape 
within which the integrated function of the wetland and upland 
components together may provide one or more of the first three PCEs 
plus other physical and biological features essential for the 
conservation of the Central population, including features that provide 
for the hydrologic function of essential breeding habitat (PCE 4), and 
habitat for small mammals that create essential refugia (PCE 4). Upland 
and wetland functions are highly integrated and interdependent in 
vernal pool complexes and, rather than trying to partition these 
functions among discrete PCEs, we included vernal pool complexes as 
their own PCE.
    A landscape that supports a vernal pool complex is typically 
grassland with areas of obstructed drainage that form the pools. The 
pools may be fed or connected by low drainage pathways called 
``swales.'' Swales are often themselves seasonal wetlands that remain 
saturated for much of the wet season, but may not be inundated long 
enough to develop strong vernal pool characteristics. Swales, due to 
their connection to adjacent pools, are considered part of the vernal 
pool complex. Some pools have a substantial watershed that contributes 
to their water inputs; others may fill almost entirely from rain 
falling directly into the pool (Hanes and Stromberg 1998). Although 
exceptions are not uncommon, the watershed generally contributes more 
to the filling of larger or deeper pools, especially playa pools. Even 
in pools filled primarily by direct precipitation, Hanes and Stromberg 
(1998) report that subsurface inflows from surrounding soils can help 
dampen water level fluctuations during late winter and early spring. 
This function is important for maintaining inundation in breeding pools 
long enough for CTS larvae to complete their aquatic life stage and 
metamorphose into adults.
    Upland areas associated with vernal pools are also an important 
source of nutrients to vernal pool organisms (Wetzel 1975). Vernal pool 
habitats derive most of their nutrients from detritus (decaying matter) 
washed into pools from adjacent uplands, and these nutrients provide 
the foundation for a vernal pool aquatic community's food chain. The 
plants, invertebrate and vertebrate animals of vernal pools, and vernal 
pool landscapes in general are important providers of food and habitat 
for waterfowl, shorebirds, wading birds, toads, frogs, and salamanders 
(Proctor et al. 1967; Krapu 1974; Swanson 1974; Morin 1987; Simovich et 
al. 1991; Silveira 1996). The uplands of vernal pool complexes may also 
provide breeding, feeding, and sheltering habitat for small mammals 
that adult CTS depend upon for food, shelter, and protection from the 
elements and predation.
    In summary, the primary constituent elements consist of four 
components. At a minimum, these elements will include suitable breeding 
locations and associated uplands or vernal pool complexes associated 
with breeding locations that are connected by barrier-free dispersal 
habitats.

Criteria Used To Identify Critical Habitat

    In our determination of critical habitat for the Central 
population, we selected areas that possess the physical and biological 
features that are essential to the conservation of the species and that 
may require special management considerations or protection. We avoided 
designating single occurrences unless such areas were considered 
unique. We also avoided areas surrounded by development or intensive 
agriculture. Agricultural lands may have been included if they were 
directly adjacent to the locations we selected to include as essential, 
thereby substantially reducing upland refugia for California tiger 
salamanders occupying that area, or were essential for connectivity 
between known occurrences. We do not have access to data on the most 
current agricultural uses in many areas of the proposed critical 
habitat and therefore are uncertain if California tiger salamander 
upland habitat may or may not remain in some locations.
    Throughout this designation, when selecting areas of critical 
habitat, we made an effort to avoid developed areas, such as housing 
developments, that are unlikely to contribute to the conservation of 
the Central population. However, we did not map critical habitat in 
sufficient detail to exclude all developed areas, or other lands 
unlikely to contain the primary constituent elements. Areas within the 
boundaries of the mapped units, such as buildings, roads, parking lots, 
railroads, airport runways and other paved areas, lawns, and other 
urban landscaped areas will not contain any of the primary constituent 
elements and thus do not constitute critical habitat. Federal actions 
limited to these areas would not trigger a section 7 consultation, 
unless they affect the species and/or the primary constituent elements 
in adjacent critical habitat.
    After identifying the primary constituent elements, we used the 
constituent elements in combination with information on CTS locations, 
geographic distribution, genetics,

[[Page 48577]]

vegetation, topography, geology, soils, distribution of CTS occurrences 
within and between vernal pool types, watersheds, current land uses, 
scientific information on the biology and ecology of the CTS, and 
conservation principles to identify essential habitat. As a result of 
this process, each of the proposed critical habitat units possesses a 
unique combination of occupied aquatic and upland habitat types, 
landscape features, surrounding land uses, vernal pool types, ponds, 
topography, and representation of geographical range, environmental 
variability, and genetic composition.
    We determined that conserving the CTS over the long-term requires a 
five-pronged approach: (1) Maintaining the current genetic structure 
across the species range; (2) maintaining the current geographic, 
elevational, and ecological distribution; (3) protecting the hydrology 
and water quality of breeding pools and ponds; (4) retaining or 
providing for connectivity between breeding locations for genetic 
exchange and recolonization; and (5) protecting sufficient barrier-free 
upland habitat around each breeding location to allow for sufficient 
survival and recruitment to maintain a breeding population over the 
long term.
    To identify areas which are essential to the conservation of the 
Central population in accordance with these criteria, we first 
identified areas within the range where we had documented records 
(e.g., museum voucher specimens, reports filed by biologists) 
indicating California tiger salamander presence (CNDDB 2003). We 
determined that essential habitat should represent the current genetic 
structure of the CTS. Genetic variation is important to fitness and 
adaptive change (Meffe and Carroll 1997). These authors state that 
losses of diversity can result in reduced evolutionary flexibility and 
declines in fitness, and that changes in the distribution of genetic 
diversity can destroy local adaptations and break up co-adapted gene 
complexes. Accordingly, we divided the current range of the Central 
population into four regions: (1) Central Valley, (2) Southern San 
Joaquin Valley, (3) East Bay, and (4) Central Coast. We further 
determined that essential habitat should represent the current 
geographic and elevational range of the species, as well as the range 
of habitat and environmental variability or other unique situations 
within each of the four regions. Conservation of the range of habitat 
types in which a species occurs helps maintain local adaptations that 
are important for the long-term viability of a species (Fugate 1992, 
King 1996, Fugate 1998). A fundamental concept in conservation biology 
is that species that are protected across their ranges have lower 
chances of extinction (Soule and Simberloff 1986, Noss et al. 2002). To 
represent this environmental variation, we selected areas with the 
highest density of Central population locations, the highest proximity 
to other Central population occurrences, known association of the 
occurrence with aquatic breeding habitat such as vernal pools or 
stockponds, and the least amount of habitat disturbance within each of 
the four regions.
    Finally, we also determined that essential habitat should be of 
sufficient size to provide enough suitable habitat to maintain 
ecological functions in both aquatic and terrestrial habitat and to 
allow for movement within and between breeding locations within each 
unit when possible. This would enable Central population from other 
locations to ``rescue'' sites which may have low numbers as a result of 
natural or human factors. To determine a general guideline for the 
amount of upland habitat necessary to support a population of adult 
CTS, we reviewed the primary literature regarding California tiger 
salamander upland habitat use, including Trenham (2000), Trenham et al. 
(2000 and 2001), and Trenham and Shaffer (in review).
    Data indicate that California tiger salamanders do not remain 
primarily in burrows close to aquatic habitats and breeding ponds, but 
instead move some distance out into the surrounding upland landscapes. 
As described in the Background section, California tiger salamanders 
have been found up to 1.2 mi (2 km) from occupied occurrences. Two 
studies conducted in Monterey and Solano counties provide the best 
available data on upland movement distances. First, the mark-recapture 
study of Trenham et al. (2001) showed that California tiger salamanders 
commonly moved between ponds separated by 2,200 ft (670 m), suggesting 
that movements of this magnitude are not rare. Second, the ongoing 
study at Olcott Lake (Solano County) has directly documented the 
presence of high densities of juvenile and adult California tiger 
salamanders at upland locations at least 1,300 ft (400 m) from this 
high-quality breeding pond.
    Recent trapping efforts captured large numbers (representing 16 
percent of total captures) of juvenile salamanders at 2,300 ft (700 m). 
Trenham and Shaffer (in review) determined that conserving upland 
habitats within 2,200 ft (670 m) of breeding ponds would protect 95 
percent of California tiger salamanders at their study location in 
Solano County. Protecting the needed upland habitat area with a radius 
of 2,200 ft (670 m) around a single pond that has a 13 ft (10 m) radius 
may yield a minimum area of 350 ac (140 ha). However, the size of any 
occurrence or breeding pond may increase the total amount of necessary 
aquatic and upland habitat space for survival of any known occurrence.
    We used 0.7 mi (1.13 km) as a guide for mapping the amount of 
upland habitat around locations where Central population is present. 
However, although the studies discussed above provide an approximation 
of the distances that California tiger salamanders can move from their 
aquatic habitats, breeding ponds, and known occupied aquatic habitats 
in search of suitable upland refugia, we recognize that upland habitat 
features will influence California tiger salamander movements in a 
particular landscape. As a result, we made adjustments to the upland 
areas to include additional areas up to the watershed boundaries or to 
include habitat containing the PCEs. In some cases we reduced the areas 
to exclude non-habitat areas (those not exhibiting the PCEs) from the 
designation.
    Section 10(a)(1)(B) of the Act authorizes us to issue permits for 
the take of listed species incidental to otherwise lawful activities. 
An incidental take permit application must be supported by a habitat 
conservation plan (HCP) that identifies conservation measures that the 
permittee agrees to implement for the species to minimize and mitigate 
the impacts of the requested incidental take. We often exclude non-
federal public lands and private lands that are covered by an existing 
operative HCP and executed implementation agreement (IA) under section 
10(a)(1)(B) of the Act from designated critical habitat because the 
benefits of exclusion outweigh the benefits of inclusion as discussed 
in section 4(b)(2) of the Act. In the case of the CTS, only the San 
Joaquin County Multi-Species HCP is a legally operating HCP that has 
identified the California tiger salamander as a covered species.
    We are aware of five HCPs under various stages of development; 
however, we are not proposing these draft HCPs for exclusion because we 
have not yet made an initial determination that they meet our issuance 
criteria, provide adequate conservation for the species, and are ready 
for public notice and comment.
    In summary, we propose critical habitat throughout the current 
range of the CTS because we believe protection of the areas is 
essential to the conservation of the species, and these areas may 
require special management.

[[Page 48578]]

We then mapped as critical habitat sufficient habitat to ensure the 
conservation of the CTS in accordance with the five elements of the 
conservation strategy described above.

Special Management Considerations or Protections

    When designating critical habitat, we assess whether the areas 
determined to be essential for conservation may require special 
management considerations or protections. Areas in need of management 
include not only the immediate locations where the species may be 
present, but additional areas adjacent to these that can provide for 
normal population fluctuations that may occur in response to natural 
and unpredictable events. The Central population may depend upon 
habitat components beyond the immediate areas where individuals of the 
species occur, if these areas support the presence of small mammals or 
are essential in maintaining ecological processes such as hydrology, 
expansion of distribution, recolonization, and maintenance of natural 
predator-prey relationships. We believe that the areas proposed for 
critical habitat may require special management considerations or 
protections due to the threats outlined below:
    (1) Activities that introduce or promote the occurrence of 
bullfrogs and fish can be significant threats to Central population 
breeding ponds.
    (2) Activities that could disturb aquatic breeding habitats during 
the breeding season.
    (3) Activities that impair the water quality of aquatic breeding 
habitat.
    (4) Activities that would reduce small mammal populations to the 
point that there is insufficient underground Central population refugia 
used for foraging, protection from predators, and shelter from the 
elements.
    (5) Activities that create barriers impassable for salamanders or 
road crossings that increase mortality in upland habitat between extant 
occurrences in breeding habitat.
    (6) Activities on adjacent uplands that disrupt vernal pool 
complexes' ability to support CTS breeding function.
    (7) Activities that introduce non-native tiger salamanders in areas 
where CTS is threatened by hybridization.

Proposed Critical Habitat Designation

    We are proposing critical habitat for the Central population 
throughout four geographic regions. The proposed critical habitat units 
described below constitute our best assessment at this time of the 
areas essential for the conservation of the Central population. The 
regions are: (1) Central Valley Region, (2) Southern San Joaquin Valley 
Region, (3) the East Bay Region, and (4) the Central Coast Region. The 
maps in this proposed rule present a pictorial representation of the 
four regions and are not accurate with regard to the dividing line 
between the Central Coast and Central Valley regions in Alameda County. 
The maps in the rule portion of this document begin with Map 7 and run 
consecutively because they follow Maps 1-6 in the proposed critical 
habitat rule for the Santa Barbara population of the California tiger 
salamander already published in the Federal Register (69 FR 3064, 
January 22, 2004). We will continue to refine these maps as we acquire 
more refined or smaller scale mapping information.

    We are proposing 47 units as critical habitat for the Central 
population. Federal lands within the San Francisco Bay National 
Wildlife Refuge, the San Luis National Wildlife Refuge Complex, and 
Fort Hunter Liggett are included in proposed critical habitat units. 
Additionally, we have proposed critical habitat on lands within East 
Bay Regional County Park. Although some Federal, State, or local 
government lands occur within the boundaries of proposed critical 
habitat, the majority of the areas proposed for critical habitat 
designation occur on privately owned land. The approximate area 
encompassed within each proposed critical habitat unit and associated 
land ownership are shown in Table 1.

    The critical habitat we are proposing for the Central population 
represents occupied aquatic and upland habitats throughout the species' 
range. Brief descriptions of the proposed critical habitat units are 
presented below. To the best of our knowledge, each unit contains 
essential aquatic, upland, and dispersal habitats.
    We believe the critical habitat units proposed below are essential 
to the conservation of the CTS because each represents a unique 
combination of aspects of geographic and ecological distribution and 
genetic diversity that meet the criteria described above for 
identifying essential habitat. Each of the proposed critical habitat 
units contains one or more of the PCEs and may require one or more of 
the special management considerations or protections described above.

Central Valley Region

    The Central Valley region generally includes an area from northern 
Yolo County south and southeast to the northern half of Madera County, 
and includes eastern Solano and Contra Costa counties. Within this 
region, we are proposing 18 critical habitat units that total 
approximately 189,137 ac (76,541 ha). The 18 proposed critical habitat 
units contain approximately 192 extant occurrences of the CTS. The 18 
proposed units occur in 4 of 17 vernal pool regions within California: 
the Solano-Colusa, Southeastern Sacramento Valley, Southern Sierra 
Foothills, and San Joaquin Valley. The units are distributed across the 
geographic extent of the region and represent the varying habitats and 
environmental conditions available for CTS in the Central Valley 
region. By including units across the geographic range of the species 
within this region we are conserving the diversity of the species and 
its habitat across its range. The approximately 192 extant occurrences 
of CTS within the Central Valley region represent some of the highest 
density and best remaining habitat for the species. Table 2 illustrates 
the acreage proposed as critical habitat within the Central Valley 
region by county.

Southern San Joaquin Valley Region

    The Southern San Joaquin Valley region includes the southern half 
of Madera County south to northeastern Kings County and northwestern 
Tulare County. Within this region, we propose six critical habitat 
units for the California tiger salamander that total approximately 
32,625 ac (13,203 ha). The six proposed critical habitat units 
encompass approximately 33 extant occurrences of the CTS and represent 
the San Joaquin Valley and Southern Sierra Foothills vernal pool 
regions. The units are distributed across the geographic extent of the 
region and represent the varying habitats and environmental conditions 
available for CTS in the Southern San Joaquin Valley region. By 
including units across the geographic range of the species within this 
region, we are conserving the diversity of the species and its habitat 
across its range. Table 3 illustrates the acreage proposed as critical 
habitat within the Southern San Joaquin Valley region by County.

Effects of Critical Habitat Designation

Section 7 Consultation

    Section 7(a)(2) of the Act requires Federal agencies, including the 
Service, to ensure that actions they fund, authorize, or carry out are 
not likely to 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. 
Individuals, organizations, States, local governments, and other 
nonfederal entities are affected by the designation of critical habitat 
only if their actions occur on Federal lands, require a Federal permit, 
license, or other authorization, or involve Federal funding.
    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 
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. 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.
    When 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. Conference reports assist the agency in eliminating conflicts 
that may be caused by the proposed action, and may include 
recommendations on actions to eliminate conflicts with, or adverse 
modifications to, proposed critical habitat. 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 on proposed critical habitat contain 
an opinion that is prepared according to 50 CFR 402.14, as if critical 
habitat were designated. We may adopt the formal conference report as 
the biological opinion when the critical habitat is designated, if no 
substantial new information or changes in the action alter the content 
of the opinion (see 50 CFR 402.10(d)).
    Activities on Federal lands that may affect the California tiger 
salamander 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 Army 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 or Federal Emergency Management Agency 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 nonfederal 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 briefly evaluate and 
describe in any proposed or final regulation that designates critical 
habitat those activities involving a Federal action that may destroy or 
adversely modify such habitat, or that may be affected by such 
designation. Activities that may destroy

[[Page 48587]]

or adversely modify critical habitat include those that appreciably 
reduce the value of critical habitat for both the survival and recovery 
of the California tiger salamander. Within critical habitat, this 
pertains only to those areas containing primary constituent elements. 
We note that such activities may also jeopardize the continued 
existence of the species.
    Common to both definitions is an appreciable detrimental effect on 
both survival and recovery of a listed species. Given the similarity of 
these definitions, actions likely to destroy or adversely modify 
critical habitat would almost always result in jeopardy to the species 
concerned, particularly when the area of the proposed action is 
occupied by the species concerned. Designation of critical habitat in 
areas occupied by the California tiger salamander is not likely to 
result in a regulatory burden above that already in place due to the 
presence of the listed species.
    Federal agencies already consult with us on activities in areas 
currently occupied by the CTS to ensure that their actions do not 
jeopardize the continued existence of the species. These actions 
include, but are not limited to:
    (1) Regulation of activities affecting waters of the United States 
by the Army Corps of Engineers 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 funded or permitted by the Federal Highway 
Administration;
    (4) Voluntary conservation measures by private landowners funded by 
the Natural Resources Conservation Service;
    (5) Regulation of airport improvement activities by the Federal 
Aviation Administration;
    (6) Licensing of construction of communication sites by the Federal 
Communications Commission;
    (7) Funding of activities by the U.S. Environmental Protection 
Agency, Department of Energy, Federal Emergency Management Agency, 
Federal Highway Administration, or any other Federal agency; and
    (8) Land management and land use actions funded, carried out, or 
permitted by the Bureau of Land Management.
    All lands proposed for designation as critical habitat are within 
the geographic area occupied by the species, and are likely to be used 
by the CTS, whether for foraging, breeding, growth of larvae and 
juveniles, dispersal, migration, genetic exchange, or sheltering. Thus, 
we consider all critical habitat units to be occupied by the species. 
Federal agencies already consult with us on activities in areas 
currently occupied by the species or if the species may be affected by 
the action to ensure that their actions do not jeopardize the continued 
existence of the species. Therefore, we believe that the designation of 
critical habitat is not likely to result in a significant regulatory 
burden above that already in place due to the presence of the listed 
species. Few additional consultations are likely to be conducted due to 
the designation of critical habitat. Nevertheless, at any given time, 
some portions of a unit may not be occupied by California tiger 
salamanders, due to climatic fluctuations, changes in population 
numbers, flood events, or other causes. Additional consultations could 
arise if a project is proposed within an unoccupied portion of a 
critical habitat unit and the primary constituent elements may be 
adversely affected by the project.

Application of Section 3(5)(A) and Exclusions Under Section 4(b)(2) of 
the Act

    We use both the definitions in section 3(5)(A) and the provisions 
of section 4(b)(2) of the Act to evaluate those specific areas that are 
proposed for designation as critical habitat as well as for those areas 
that are subsequently finalized (i.e., designated as critical habitat). 
On that basis, it has been our policy not to include in proposed 
critical habitat, or exclude from designated critical habitat, those 
areas: (1) Not biologically essential to the conservation of a species; 
(2) covered by an individual (project-specific) or regional Habitat 
Conservation Plan (HCP) that covers the subject species; (3) covered by 
a complete and approved Integrated Natural Resource Management Plan 
(INRMP) for specific DOD installations; and (4) covered by an adequate 
management plan or agreement that protects the primary constituent 
elements of the habitat.
    We have not excluded any lands from this proposal pursuant to 
sections 3(5)(A) and 4(b)(2) of the Act. Potential areas which we are 
considering to exclude based on section 4(b)(2) of the Act include: 
areas on Fort Hunter Liggett and the Concord Naval Weapons Station and 
lands within any other DOD facilities; lands within Fish and Wildlife 
National Wildlife Refuges that have completed CCPs or have concluded 
intra-Service section 7 consultation for the species; lands within 
State Wildlife Areas or Ecological Reserves that have developed and 
implemented management plans for the species; and lands covered under 
any legally operating NCCP/HCP where the California tiger salamander is 
a covered species. The San Luis National Wildlife Refuge Complex 
(SLNWR) (units 12 and 13 in the Central Valley Region) and the Don 
Edwards San Francisco Bay National Wildlife Refuge (SFBNWR) (Unit 4 in 
the East Bay Region) have areas that are included in the proposed 
designation. The SLNWR is scheduled to start development of a CCP in 
2005, and the SFBNWR is scheduled to start the CCP process in 2008.
    In addition, we are also considering exclusion of private lands 
being managed for the long-term conservation of the California tiger 
salamander through agreements or other mechanisms; municipal water 
district lands or other local government lands that develop management 
plans for the long-term conservation of the species; other State or 
private easement lands that develop management plans which ensure the 
conservation of the California tiger salamander.
    This proposed rule includes two proposed critical habitat units at 
Fort Hunter Liggett. Fort Hunter Liggett does not have a signed INRMP 
that affords effective conservation for the CTS and has no approved 
management plan for the species. During the proposal period, we hope to 
work with private landowners on developing conservation agreements that 
would protect the extant occurrences of the species. We are aware of 
the landowner concerns that this proposal has on the ranching community 
and look forward to receiving more current information from ranchers 
and other landowners to improve and refine our proposed critical 
habitat units. If we can complete conservation agreements with ranch 
landowners and other interested landowners, we may exclude lands 
covered by conservation agreements from the final critical habitat 
designation for the CTS.

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 CTS

[[Page 48588]]

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. We will reopen the comment period and 
accept comments from the public about the economic impacts from the 
proposed critical habitat and any other comments from landowners and 
the public. At that time, copies of the draft economic analysis will be 
available for downloading from the Internet at http://sacramento.fws.gov, or by contacting the Sacramento Fish and Wildlife 
Office directly (see ADDRESSES section)

Peer Review

    In accordance with our joint policy published in the Federal 
Register on July 1, 1994 (59 FR 34270), we will seek the expert 
opinions of at least three appropriate and 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 during preparation of a final 
rulemaking. Accordingly, the final decision may differ from this 
proposal.

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.

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, and so forth) 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

    Due to the tight timeline for publication in the Federal Register, 
the Office of Management and Budget (OMB) has not formally reviewed 
this rule. Office of Management and Budget makes the final 
determination of significance 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 the specific area as critical habitat.
    Within these areas, the types of Federal actions or authorized 
activities that we have identified as potential concerns are:
    (1) Regulation of activities affecting waters of the United States 
by the Army 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 funded or permitted by the Federal Highway 
Administration;
    (4) Voluntary conservation measures by private landowners funded by 
the Natural Resources Conservation Service;
    (5) Regulation of airport improvement activities by the Federal 
Aviation Administration;
    (6) Licensing of construction of communication sites by the Federal 
Communications Commission;
    (7) Funding of activities by the U.S. Environmental Protection 
Agency, Department of Energy, Federal Emergency Management Agency, 
Federal Highway Administration, or any other Federal agency; and
    (8) Land management and land use actions funded, carried out, or 
permitted by the Bureau of Land Management.
    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 comments.

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 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.
    At this time, the Service lacks the available economic information 
necessary to provide an adequate factual basis for the required RFA 
finding. Therefore, the RFA finding is deferred until completion of the 
draft economic analysis prepared pursuant to section 4(b)(2) of the ESA 
and E.O. 12866. This draft economic analysis will provide the required 
factual basis for the RFA finding. Upon completion of the draft 
economic analysis, the Service will publish a notice of availability of 
the draft economic analysis of the proposed designation and reopen the 
public comment period for the proposed designation for an additional 60 
days. The Service will include with the notice of availability, as 
appropriate, an initial regulatory flexibility analysis or a 
certification that the rule will not have a significant economic impact 
on a substantial number of small entities accompanied by the factual 
basis for that determination. The Service has concluded that deferring 
the RFA finding until completion of the draft economic analysis is 
necessary to meet the purposes and requirements of the RFA. Deferring 
the RFA finding in this manner will ensure that the Service makes a 
sufficiently informed determination based on adequate economic 
information and provides the necessary opportunity for public comment.
    To determine if the rule would affect a substantial number of small 
entities, we consider the number of small

[[Page 48589]]

entities affected within particular types of economic activities (e.g., 
housing development, grazing, oil and gas production, timber 
harvesting, etc.). We considered each industry individually to 
determine if certification is appropriate. In estimating the numbers of 
small entities potentially affected, we also consider whether their 
activities have any Federal involvement; some kinds of activities are 
unlikely to have any Federal involvement and so will not be affected by 
critical habitat designation. Designation of critical habitat only 
affects activities conducted, funded, or permitted by Federal agencies; 
non-Federal activities are not affected by the designation.
    If this critical habitat designation is finalized, Federal agencies 
must consult with us if their activities may affect designated critical 
habitat. Consultations to avoid the destruction or adverse modification 
of critical habitat would be incorporated into the existing 
consultation process.
    Since the Central population was proposed as a threatened species 
on May 23, 2003 (68 FR 28648), we have conferenced with Federal 
agencies and applicants, or are in the process of conferencing, on 25 
projects within the range of the Central population. Seventeen of these 
conferences are being conducted in accordance with the procedures for 
formal consultation in accordance with 50 CFR 402.10. The remaining 
eight have been informal. These conferences have concerned activities 
such as by developers, municipalities, businesses, and others. Formal 
and informal conferences regarding the Central population usually 
result in recommendations to avoid or minimize incidental take and 
offset permanent loss of habitat. In reviewing these conferences and 
the activities involved in light of proposed critical habitat, we do 
not believe the outcomes would have been different in areas designated 
as critical habitat. However, as a result of not having the economic 
analysis completed on the proposed designation of critical habitat for 
the CTS, we will not make a determination or certify that the action 
will not have a significant economic impact on a substantial number of 
small entities, and an initial regulatory flexibility analysis is not 
required until the completion of a draft economic analysis.
    This discussion is based upon the information regarding potential 
economic impact that is available to us at this time. This assessment 
of economic effect may be modified prior to final rulemaking 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 an Executive Order (E.O. 
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 CTS is not a 
significant regulatory action under Executive Order 12866, and it 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.)

    In accordance with the Unfunded Mandates Reform Act (2 U.S.C. 
1501), the Service makes the following findings:
    (a) This rule will not produce a Federal mandate. In general, a 
Federal mandate is a provision in legislation, statute, or regulation 
that would impose an enforceable duty upon State, local, or tribal 
governments or the private sector and includes both ``Federal 
intergovernmental mandates'' and ``Federal private sector mandates.'' 
These terms are defined in 2 U.S.C. 658(5)-(7). ``Federal 
intergovernmental mandate'' includes a regulation that ``would impose 
an enforceable duty upon State, local, or tribal governments'' with two 
exceptions. It excludes ``a condition of Federal assistance.'' It also 
excludes ``a duty arising from participation in a voluntary Federal 
program,'' unless the regulation ``relates to a then-existing Federal 
program under which $500,000,000 or more is provided annually to State, 
local, and tribal governments under entitlement authority,'' if the 
provision would ``increase the stringency of conditions of assistance'' 
or ``place caps upon, or otherwise decrease, the Federal Government's 
responsibility to provide funding'' and the State, local, or tribal 
governments ``lack authority'' to adjust accordingly. (At the time of 
enactment, these entitlement programs were: Medicaid; AFDC work 
programs; Child Nutrition; Food Stamps; Social Services Block Grants; 
Vocational Rehabilitation State Grants; Foster Care, Adoption 
Assistance, and Independent Living; Family Support Welfare Services; 
and Child Support Enforcement.) ``Federal private sector mandate'' 
includes a regulation that ``would impose an enforceable duty upon the 
private sector, except (i) a condition of Federal assistance; or (ii) a 
duty arising from participation in a voluntary Federal program.''
    The designation of critical habitat does not impose a legally 
binding duty on non-Federal government entities or private parties. 
Under the Act, the only regulatory effect is that Federal agencies must 
ensure that their actions do not destroy or adversely modify critical 
habitat under section 7. While non-Federal entities who receive Federal 
funding, assistance, or permits or otherwise require approval or 
authorization from a Federal agency for an action may be indirectly 
impacted by the designation of critical habitat, the legally binding 
duty to avoid destruction or adverse modification of critical habitat 
rests squarely on the Federal agency. Furthermore, to the extent that 
non-Federal entities are indirectly impacted because they receive 
Federal assistance or participate in a voluntary Federal aid program, 
the Unfunded Mandates Reform Act would not apply; nor would critical 
habitat shift the costs of the large entitlement programs listed above 
on to State governments.
    (b) We do not believe that this rule will significantly or uniquely 
affect small governments. 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 is not likely to jeopardize 
the species, and no further regulatory impacts from the designation of 
critical habitat are anticipated. Because we believe this rule will not 
significantly or uniquely affect small governments, a Small Government 
Agency Plan is not required. We will, however, further evaluate this 
issue as we conduct our economic analysis and revise this assessment if 
appropriate.

Takings

    In accordance with Executive Order 12630, the rule does not have 
significant takings implications. A takings

[[Page 48590]]

implication assessment is not required. The designation of critical 
habitat affects only Federal agency actions. The rule will not increase 
or decrease the current restrictions on private property concerning 
take of the CTS. Due to current public knowledge of the species' 
protection, the prohibition against take of the species both within and 
outside of the designated areas, and the fact that critical habitat 
provides no incremental restrictions, we do not anticipate that 
property values will be affected by the proposed critical habitat 
designation. While real estate market values may temporarily decline 
following designation, due to the perception that critical habitat 
designation may impose additional regulatory burdens on land use, we 
expect any such impacts to be short term. Additionally, critical 
habitat designation does not preclude development of HCPs and issuance 
of incidental take permits. Owners of areas that are included in the 
designated critical habitat will continue to have opportunity to use 
their property in ways consistent with the survival of the CTS.

Federalism

    In accordance with Executive Order 13132, the rule does not have 
significant Federalism effects. A Federalism assessment is not 
required. In keeping with DOI and Department of Commerce policy, we 
requested information from, and coordinated development of, this 
proposed critical habitat designation with appropriate State resource 
agencies in California. The designation of critical habitat in areas 
currently occupied by the CTS imposes no additional restrictions to 
those currently in place and, therefore, has little incremental impact 
on State and local governments and their activities. The designation 
may have some benefit to these governments 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 
these 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 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 have proposed designating 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 California tiger 
salamander.

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

    This rule does not contain any new collections of information that 
require approval by OMB under the Paperwork Reduction Act. 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 proposed 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 readily acknowledge our 
responsibility to communicate meaningfully with recognized Federal 
Tribes on a government-to-government basis. We have determined that 
there are no tribal lands essential for the conservation of the Central 
California population of the California tiger salamander. Therefore, 
proposed designation of critical habitat for the Central California 
population of the California tiger salamander has not been designated 
on Tribal lands.

January 22, 2004, at 69 FR 3064, is proposed to be further amended by 
revising the heading and adding paragraphs (11) through (62) as 
follows:

    (11) Critical habitat units are depicted for the Central California 
population, California, on the maps below.
    (12) The primary constituent elements (PCEs) of critical habitat 
for the Central population of the California tiger salamander (CTS) are 
the habitat components that provide:
    (i) Standing bodies of fresh water, including natural and man-made 
(e.g., stock) ponds, vernal pools, vernal pool complexes, and other 
ephemeral or permanent water bodies that typically become inundated 
during winter rains and hold water for a sufficient length of time 
(i.e., 12 weeks) necessary for the species to complete the aquatic 
portion of its life cycle.
    (ii) Barrier-free uplands adjacent to extant occurrence locations 
that contain small mammal burrows, including but not limited to burrows 
created by the California ground squirrel (Spermophilus beecheyi) and 
Botta's pocket gopher (Thomomys bottae). Small mammals are essential in 
creating the underground habitat that adult California tiger 
salamanders depend upon for food, shelter, and protection from the 
elements and predation.
    (iii) Upland areas between extant occurrence locations (paragraphs 
1 and 12(i) for this proposed designation) and areas with small mammal 
burrows (paragraphs 2 and 12(ii) for this proposed designation) that 
allow for dispersal among such sites.
    (iv) The geographic, topographic, and edaphic features that support 
aggregations or systems of hydrologically interconnected pools, swales, 
and other ephemeral wetlands and depressions within a matrix of 
surrounding uplands that together form hydrologically and ecologically 
functional units called vernal pool complexes. These features 
contribute to the filling and drying of the vernal pool, maintain 
suitable periods of pool inundation for larval salamanders and their 
food sources, and providing breeding, feeding, and sheltering habitat 
for juvenile and adult salamanders and small mammals that create burrow 
systems essential for CTS estivation.
    (13) Critical habitat does not include existing features and 
structures, such as buildings, aqueducts, airports, roads, and other 
developed areas not containing one or more of the primary constituent 
elements.
    (14) Critical Habitat Map Units. Data layers defining map units 
were created on a base of USGS 7.5' quadrangles, and critical habitat 
units were then mapped using Universal Transverse Mercator (UTM) 
coordinates.
