DEPARTMENT OF THE INTERIOR 

Fish and Wildlife Service 

50 CFR Part 17 

RIN 1018–AT93 

Endangered and Threatened Wildlife 

and Plants; Proposed Designation of 

Critical Habitat for the Alameda 

Whipsnake 

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 

Alameda whipsnake (Masticophis 

lateralis euryxanthus) pursuant to the 

Endangered Species Act of 1973, as 

amended (Act). In total, approximately 

203,342 acres (ac) (82,289 hectares (ha)) 

fall within the boundaries of the 

proposed critical habitat designation. 

The proposed critical habitat is located 

in Contra Costa, Alameda, San Joaquin, 

and Santa Clara counties, California. 

DATES: We will accept comments from 

all interested parties until December 19, 

2005. We must receive requests for 

public hearings, in writing, at the 

address shown in the ADDRESSES section 

by December 2, 2005. 

ADDRESSES: If you wish to comment, 

you may submit your comments and 

materials concerning this proposal by 

any one of several methods:

resulting from this proposal will be as 

accurate and as effective as possible. 

Therefore, comments or suggestions 

from the public, other concerned 

governmental agencies, the scientific 

community, industry, or any other 

interested party concerning this 

proposed rule are hereby solicited. 

Comments particularly are sought 

concerning: 

(1) The reasons 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 subspecies due to designation; 

(2) Specific information on the 

amount and distribution of Alameda 

whipsnake habitat and occurrence 

records, and what habitat features are 

essential to the conservation of the 

subspecies and why; 

(3) Land use designations and current 

or planned activities in the subject areas 

and their possible impacts on proposed 

critical habitat; 

(4) Information regarding the benefits 

of excluding specific lands from, or 

including specific lands in, the 

designation of critical habitat including 

but not limited to, State lands contained 

within the Mount Diablo State Park in 

Contra Costa County; Department of 

Energy lands in Alameda and San 

Joaquin Counties; and Bureau of Land 

Management lands within Contra Costa 

County, including specific information 

about existing management plans in 

place for these lands, and the provisions 

of such plans for the conservation of the 

Alameda whipsnake and its habitat; 

(5) Any foreseeable economic, 

national security, or other potential 

impacts resulting from the proposed 

and/or final designation of critical 

habitat and, in particular, any impacts 

on small entities; and

Designation of Critical Habitat Provides 

Little Additional Protection to 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. 

Federal Register / Vol. 70, No. 200 / Tuesday, October 18, 2005 / Proposed Rules 60609 

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 466 species or 37 percent of the 

1,268 listed species in the United States 

under the jurisdiction of the Service 

have designated critical habitat. 

We address the habitat needs of all 

1,268 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. 

We note, however, that two courts 

found our definition of adverse 

modification to be invalid (March 15, 

2001, decision of the United States 

Court Appeals for the Fifth Circuit, 

Sierra Club v. U.S. Fish and Wildlife 

Service et al., F.3d 434 and the August 

6, 2004, Ninth Circuit judicial opinion, 

Gifford Pinchot Task Force v. United 

State Fish and Wildlife Service). In 

response to these decisions, we are 

reviewing the regulatory definition of 

adverse modification in relation to the 

conservation of the 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 

to sue relative to critical habitat, and to 

comply with the growing number of 

adverse court orders. As a result, 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 no ability to 

provide for adequate public 

participation or to ensure a defect-free 

rulemaking process before making 

decisions on listing and critical habitat 

proposals due to the risks associated 

with noncompliance with judiciallyimposed deadlines. This in turn fosters 

a second round of litigation in which 

those who fear adverse impacts from 

critical habitat designations challenge 

those designations. The cycle of 

litigation appears endless, is very 

expensive, and in the final analysis 

provides relatively little additional 

protection to listed species. 

The costs resulting from the 

designation include legal costs, the cost 

of preparation and publication of the 

designation, the analysis of the 

economic effects and the cost of 

requesting and responding to public 

comment, and in some cases the costs 

of compliance with the National 

Environmental Policy Act (NEPA) (42 

U.S.C. 4321–4347). 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 they directly reduce the 

funds available for direct and tangible 

conservation actions. 

Background 

Subspecies Description 

The Alameda whipsnake is a member 

of the family Colubridae (Stebbins 

1985), and one of two subspecies of 

Masticophis lateralis. The Alameda 

whipsnake is a slender, fast-moving, 

diurnally active snake with a slender 

neck, broad head, and large eyes. 

Alameda whipsnakes range from 3 to 4 

feet (ft) (91 to 122 centimeters (cm)) in 

length. The Alameda whipsnake is 

distinguished from the more common 

chaparral whipsnake (Masticophis 

lateralis lateralis) by a sooty black back 

area, wider yellow-orange stripes that 

run laterally down each side, the lack of 

a dark line across the scale near the tip 

of the nose, an uninterrupted light stripe 

between the tip of the nose and eye, and 

the virtual absence of spotting on the 

underside of the head and neck. For 

more information on the Alameda 

whipsnake, refer to the final listing rule 

and previous final critical habitat 

designation published in the Federal 

Register on December 5, 1997 (62 FR 

64306), and October 3, 2000 (65 FR 

58933), respectively. 

Life History 

Members of the genus Masticophis are 

slender, fast-moving, diurnal snakes 

with a broad head, large eyes, and 

slender neck. When hunting, these 

snakes commonly move with the head 

held high and occasionally move it from 

side to side, possibly to aid in depth 

perception. Prey is seized with great 

speed, pinioned under loops of the 

body, and engulfed without 

constriction. The Alameda whipsnake is 

a lizard-eating specialist, although its 

diet may include other prey (e.g.), 

rattlesnakes and nesting birds) 

depending on an individual’s size, sex, 

age, and location. These snakes are good 

climbers that can escape into scrub or 

trees. Additionally, they seek shelter in 

rock piles, outcrops, or small mammal 

burrows (Stebbins 1985). 

In a study of the thermal responses of 

the Alameda whipsnake, Hammerson 

(1979) observed that snakes emerged 

from burrows in the morning with a low 

body temperature, often exposing just 

the head first, then basking in full or 

partial sun until they reached a body 

temperature of 91.4 to 93.4 degrees 

Fahrenheit (33.0 to 34.1 degrees 

Celsius). Alameda whipsnakes 

maintained a high body temperature 

(compared to other snakes) during the 

day, and retreated to burrows when soil 

surface temperatures began to fall. 

Alameda whipsnakes have a higher 

degree of body temperature stability 

than other snakes (Swaim 1994). 

Alameda whipsnakes maintain this 

high, stable body temperature by using 

open and partially open and or low 

growing shrub communities that 

provide cover from predators. Alameda 

whipsnakes require a mosaic of sunny 

and shady areas to regulate their body 

temperature. 

Swaim (1994) used trapping and radio 

telemetry to study several aspects of 

Alameda whipsnake life history at 

multiple sites in Alameda and Contra 

Costa counties. Adult snakes had a 

bimodal seasonal activity pattern with 

peaks during the spring mating season 

and a smaller peak during late summer 

and early fall. Although short, aboveground movements may occur during 

the winter, Alameda whipsnakes 

generally retreat in November into a 

hibernaculum (i.e.), a protective site 

where the snakes remain over the 

60610 Federal Register / Vol. 70, No. 200 / Tuesday, October 18, 2005 / Proposed Rules 

winter) and emerge in March. Courtship 

and mating were observed from late 

March through mid-June. During this 

time males move around throughout 

their home ranges, but females appear to 

remain at or near their hibernacula 

where mating occurs. The home range of 

a male Alameda whipsnake ranged from 

4.7 to 21.5 ac (1.9 to 8.7 ha) in size 

(mean of 13.6 ac (5.5 ha), n = 4), and 

showed a high degree of spatial overlap. 

Suspected egg-laying sites for two 

female snakes were located in grassland 

with scattered shrub habitat. Similarly, 

recent trapping studies have 

documented captures of spent females 

(i.e., morphologically identifiable as 

having recently laid eggs) within scrub 

communities (Swaim 2002a), suggesting 

that these areas are in close association 

with egg-laying sites. Typically, 

clutches of 6 to 11 eggs are laid between 

May and July (Stebbins 1985), with 

young hatching and emerging in late 

summer to early fall (Swaim 1994). 

These hatchlings have been seen and 

captured above ground from August 

through November. Prey items were 

occasionally detected in the stomachs of 

captured hatchlings during this period, 

indicating that some hatchlings feed 

prior to winter hibernation. 

Three individual snakes monitored by 

Swaim (1994) for nearly an entire 

activity season appeared to maintain 

stable home ranges. Movements of these 

individuals were multi-directional and 

individual snakes returned to specific 

areas and retreat sites after long 

intervals of nonuse. Snakes had one or 

more core areas (i.e., areas of 

concentrated use) within their home 

range as described above, with large 

areas of the home range receiving little 

use. 

Geographical Range 

The Alameda whipsnake currently 

inhabits the inner coast range mostly in 

Contra Costa and Alameda counties 

(Jennings 1983; McGinnis 1992; Swaim 

1994), with additional occurrence 

records in San Joaquin and Santa Clara 

counties (CNDDB 2005; Swaim 2004). 

Compared to the much more common 

chaparral whipsnake, the Alameda 

whipsnake subspecies historic range has 

always had a very restricted 

distribution. The subspecies historic 

range most likely included the entirety 

of the coastal scrub and oak woodland 

communities throughout the East Bay in 

Contra Costa, Alameda, and parts of San 

Joaquin and Santa Clara counties 

(McGinnis 1992). The current 

distribution of the subspecies has been 

reduced from the known historic range 

to five separate areas with little or no 

interchange due to habitat loss, 

alteration, and fragmentation. The five 

populations remain centered in: (1) 

Sobrante Ridge, Tilden/Wildcat 

Regional Parks to the Briones Hills, in 

Contra Costa County (Tilden-Briones 

population); (2) Oakland Hills, Anthony 

Chabot area to Las Trampas Ridge, in 

Contra Costa County (Oakland-Las 

Trampas population); (3) Hayward Hills, 

Palomares area to Pleasanton Ridge, in 

Alameda County (Hayward-Pleasanton 

Ridge population); (4) Mount Diablo 

vicinity and the Black Hills, in Contra 

Costa County (Mount Diablo-Black Hills 

population); and (5) Wauhab Ridge, Del 

Valle area to the Cedar Mountain Ridge, 

in (Sunol-Cedar Mountain population). 

For more information on the current 

distribution of the subspecies, refer to 

the Federal Register notices listing the 

species on December 5, 1997 (62 FR 

64306) and the previous designation of 

critical habitat on October 3, 2000 (65 

FR 58933). 

Habitat 

The distribution of the Alameda 

whipsnake coincides most closely with 

scrublands broken by grassy patches, 

and rocky hillsides (Stebbins 1985). 

Recent telemetry data indicate that, 

although home ranges of Alameda 

whipsnakes are centered on scrub plant 

communities, Alameda whipsnakes 

frequently venture out into adjacent 

habitats, including grassland, oak 

savannah, and occasionally oak-bay 

woodland. The Alameda whipsnake 

occurs typically within a mosaic of 

habitat types containing scrub/shrub 

(chamise-redshank chaparral, mixed 

chaparral, coastal scrub) communities, 

with a significant component of annual 

grassland, as well as other wooded 

habitats such as blue oak-foothill pine, 

blue oak woodland, coastal oak 

woodland, valley oak woodland, and 

riparian communities (Sawyer and 

Keeler-Wolf 1995; Mayer and 

Laudenslayer 1988; CDFG 1998) or rock 

outcrops. Alameda whipsnakes exhibit a 

preference for open-canopy stands and 

habitats with woody debris and exposed 

rock outcrops because these habitats 

provide areas for basking, cover from 

predators, and an ample source of prey. 

Until recently, Alameda whipsnakes 

were most often found on southeast, 

south, and southwest facing slopes 

(McGinnis 1992; Swaim 1994). Swaim 

(1994) reported that Alameda 

whipsnakes have been shown to travel 

distances greater than 500 ft (152.5 

meters (m)) over grassland and other 

vegetation types and communities to 

exposed rock outcrops. 

However, additional study has 

established that concentrated activity 

and/or movement occurs on all slope 

aspects, including northern exposures, 

riparian areas (e.g. stream corridors), 

and through both open and closed 

canopy woodlands (Swaim 2000; Swaim 

2002b; Swaim 2004; Swaim 2005b–d). 

Recent data from incidental sighting on 

free-ranging Alameda whipsnakes and 

recapture trapping surveys show regular 

use of habitats a distance of greater than 

656 ft (200 m) from scrub and chaparral 

and include observations of Alameda 

whipsnakes up to 23,950 yards (yd) 

(7,300 m) from scrub (Swaim 2003; 

Swaim 2004; Swaim 2005b), and 

movement of marked snakes of several 

thousand feet (meters) (Swaim 2005c) in 

a matter of 4 to 10 days. 

Telemetry data indicate that Alameda 

whipsnakes remain in grasslands for 

periods of several hours to weeks at a 

time (Swaim 1994). Grassland habitats 

are extensively used by male Alameda 

whipsnakes during the spring mating 

season. Female Alameda whipsnakes 

use grassland areas after mating, 

possibly in search of egg-laying sites. 

Rock outcrops are considered an 

important feature of Alameda 

whipsnake habitat because they provide 

shelter and potential hibernacula. Rock 

outcrops also support lizard 

populations. Lizards, especially the 

western fence lizard (Sceloporus 

occcidentalis), are a major prey item of 

Alameda whipsnakes (Stebbins 1985; 

Swaim 1994). Most telemetered 

locations of Alameda whipsnakes were 

within rock outcrops and talus. 

Threats 

Current threats to Alameda 

whipsnake habitat are urban 

development and associated impacts 

that result from increased human 

population densities, fire suppression 

and resulting likelihood of catastrophic 

wildfires, increased predation pressure, 

and incompatible grazing practices. 

McGinnis (1992) identified the loss of 

large blocks of prime habitat due to 

relatively recent urban development as 

the principle reason for the decline in 

the subspecies. The central and western 

portions of Alameda and Contra Costa 

counties are highly urbanized and 

continue to be subjected to increased 

urbanization. Habitat fragmentation 

from urban development and associated 

infrastructure (e.g., highway and road 

construction) has led to isolation of the 

five populations by wholly preventing 

or severely reducing movement of 

individuals between each of the areas 

occupied by the five populations. 

Consequently, these activities have 

reduced the total amount of habitat 

available for the Alameda whipsnake. 

Federal Register / Vol. 70, No. 200 / Tuesday, October 18, 2005 / Proposed Rules 60611 

Previous Federal Action 

On December 5, 1997, we published 

a final rule listing the Alameda 

whipsnake as threatened (62 FR 64306). 

On October 3, 2000, we published a 

final rule designating critical habitat for 

the Alameda whipsnake within 

Alameda, Contra Costa, San Joaquin, 

and Santa Clara counties (65 FR 58933). 

On June 7, 2001, the Home Builders 

Association of Northern California and 

others filed a lawsuit in the Eastern 

District of California against the Service, 

challenging the final designation of 

critical habitat for the Alameda 

whipsnake (Home Builders Association 

of Northern California, et al. v. U.S. Fish 

and Wildlife Service, et al., CV F 01–

5722 AWI SMS). On May 9, 2003, the 

U.S. District Judge vacated and 

remanded the October 3, 2000, final rule 

designating critical habitat for the 

Alameda whipsnake. On January 14, 

2004, the Service was ordered to 

complete and publish a proposed rule 

on critical habitat designation for the 

Alameda whipsnake no later than 

October 1, 2005, and to complete and 

publish a final rule no later than 

October 1, 2006. For more information 

on previous Federal actions concerning 

the Alameda whipsnake, refer to the 

final listing rule published in the 

Federal Register (62 FR 64306). 

Critical Habitat 

Critical habitat is defined in section 3 

of the Act as—(i) the specific areas 

within the geographical area occupied 

by a species, at the time it is listed in 

accordance with the Act, on which are 

found those physical or biological 

features (I) essential to the conservation 

of the species and (II) that may require 

special management considerations or 

protection; and (ii) specific areas 

outside the geographical area occupied 

by a species at the time it is listed, upon 

a determination that such areas are 

essential for the conservation of the 

species. ‘‘Conservation’’ 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. 

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 are likely to 

result in the destruction or adverse 

modification of critical habitat. The 

designation of critical habitat does not 

affect land ownership or establish a 

refuge, wilderness, reserve, preserve, or 

other conservation area. Such 

designation does not allow government 

or public access to private lands. 

To be included in a critical habitat 

designation, the habitat within the area 

occupied by the species at the time of 

listing must first have features that are 

‘‘essential to the conservation of the 

species.’’ Critical habitat designations 

identify, to the extent known using the 

best scientific data available, habitat 

areas that provide essential life cycle 

needs of the species (i.e., areas on which 

are found the primary constituent 

elements (PCEs), as defined at 50 CFR 

424.12(b)). 

Habitat occupied at the time of listing 

may be included in critical habitat only 

if the essential features thereon may 

require special management or 

protection. Thus, we do not include 

areas where existing management is 

sufficient to conserve the species. (As 

discussed below, such areas may also be 

excluded from critical habitat pursuant 

to section 4(b)(2) of the Act.) 

Accordingly, when the best available 

scientific data do not demonstrate that 

the conservation needs of the species so 

require, we will not designate critical 

habitat in areas outside the geographical 

area occupied by the species at the time 

of listing. An area currently occupied by 

the species but was not known to be 

occupied at the time of listing will 

likely be essential to the conservation of 

the species and, therefore, included in 

the critical habitat designation. 

The Service’s Policy on Information 

Standards Under the Act, published in 

the Federal Register on July 1, 1994 (59 

FR 34271), and Section 515 of the 

Treasury and General Government 

Appropriations Act for Fiscal Year 2001 

(Pub. L. 106–554; H.R. 5658) and the 

associated Information Quality 

Guidelines issued by the Service, 

provide criteria, establish procedures, 

and provide guidance to ensure that 

decisions made by the Service represent 

the best scientific data available. They 

require Service biologists, to the extent 

consistent with the Act and with the use 

of the best scientific data available, to 

use primary and original sources of 

information as the basis for 

recommendations to designate critical 

habitat. When determining which areas 

are critical habitat, a primary source of 

information is generally the listing 

package for the species. Additional 

information sources include the 

recovery plan for the species, articles in 

peer-reviewed journals, conservation 

plans developed by States and counties, 

scientific status surveys and studies, 

biological assessments, or other 

unpublished materials and expert 

opinion or personal knowledge. All 

information is used in accordance with 

the provisions of Section 515 of the 

Treasury and General Government 

Appropriations Act for Fiscal Year 2001 

(Pub. L. 106–554; H.R. 5658) and the 

associated Information Quality 

Guidelines issued by the Service. 

Section 4 of the Act requires that we 

designate critical habitat on the basis of 

the best scientific data available. Habitat 

is often dynamic and may change over 

time due to vegetational succession, 

climate, or catastrophic events (e.g., fire, 

landslides). As a result of habitat change 

a species may move from one area to 

another over time. Furthermore, we 

recognize that designation of critical 

habitat may not include all of the 

habitat areas that may eventually be 

determined to be necessary for the 

recovery of the species. For these 

reasons, critical habitat designations do 

not signal that habitat outside the 

designation is unimportant or may not 

be required for recovery. 

Areas that support populations, but 

are outside the critical habitat 

designation, will continue to be subject 

to conservation actions implemented 

under section 7(a)(1) of the Act and to 

the regulatory protections afforded by 

the section 7(a)(2) jeopardy standard, as 

determined on the basis of the best 

available information at the time of the 

action. Federally funded or permitted 

projects affecting listed species outside 

their designated critical habitat areas 

may still result in jeopardy findings in 

some cases. Similarly, critical habitat 

designations made on the basis of the 

best available information at the time of 

designation will not control 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 

As required by section 4(b)(1)(A) of 

the Act, we use the best scientific data 

available in determining areas that 

contain the features that are essential to 

the conservation of the Alameda 

whipsnake, including information 

gathered for the Draft Recovery Plan, 

information from local subspecies 

experts, published and unpublished 

research papers (e.g., peer-reviewed 

journal articles in the public domain), 

academic theses, abstracts of 

presentations at scientific meetings, 

notes from our attendance at such 

presentations, consultation with 

recognized experts in the field, and 

review of case studies of other critical 

habitat designations. We assembled the 

60612 Federal Register / Vol. 70, No. 200 / Tuesday, October 18, 2005 / Proposed Rules 

best and most recently available 

information on soil, vegetation, 

Alameda whipsnake records, 

topography, urban development, road 

systems, and aerial imagery, into a 

Geographic Information Systems (GIS) 

database. We are not proposing to 

designate any areas as critical habitat 

that lie outside the geographical area 

presently occupied by the subspecies. 

We have also reviewed available 

information that pertains to the habitat 

requirements of this subspecies, 

including reports submitted during 

section 7 consultations and by biologists 

holding section 10(a)(1)(A) recovery 

permits; research published in peerreviewed articles and presented in 

academic theses and agency reports; and 

regional GIS coverages. 

As mentioned in the Habitat and 

Primary Constituent Elements sections, 

Alameda whipsnakes have the 

capability and need for long range 

movement. These movements are 

essential for establishment of home 

ranges, finding retreats, maintenance of 

gene flow, recolonization of habitat, 

relocation in response to disturbance, 

and finding mates. Such movements 

have been documented by observation 

of snake distance from scrub habitat 

(Swaim 2003) and tracking of snake 

movements (Swaim 2005 b–d), and are 

well within the general range as 

exemplified by other snake species in 

the same family (Loughheed et al. 1999; 

Blouin-Demers and Weatherhead 2002). 

Habitat determined to be occupied 

included that habitat between recorded 

observations within the capable and 

necessary range of movement, which 

has relatively high quality habitat for 

the Alameda whipsnake, PCEs, and 

other factors (see Criteria for 

Identification of Critical Habitat, below). 

Only such occupied habitat has been 

considered in the designation of critical 

habitat for this subspecies. All proposed 

units were occupied at the time of 

listing and are currently occupied by the 

Alameda whipsnake. 

A GIS database was constructed to 

overlay key layers which served as 

indices of habitat quality. The critical 

habitat boundary was adjusted as 

warranted by major landforms and 

features (e.g., ridgelines, water courses), 

soils, development, distance from 

known records, and barriers to 

movement. 

We determined that soil type could be 

employed to distinguish those areas 

most likely to support Alameda 

whipsnake and/or its PCEs. To 

determine suitability, soils were ranked 

by the number of Alameda whipsnake 

records falling within individual soil 

types. We decided to map those soil 

layers with a minimum of three 

Alameda whipsnake records. Because of 

the inherent biases in Alameda 

whipsnake data collection techniques, 

we believe this criterion does not overrepresent areas with a single 

observation, nor under-represent those 

areas that had numerous records as a 

consequence of more frequent scientific 

study. The soil types associated with 

three or more Alameda whipsnake 

records included rock outcrop, wisflatarburua-san timoteo complex, various 

types of loams, rocky loams, clay loams, 

and silt loams, and riverwash. Although 

rock outcrops and rocky soils accounted 

for a disproportionate number of 

Alameda whipsnake observations, 

multiple Alameda whipsnake records 

were also associated with other soil 

types. Many of the same soils associated 

with multiple Alameda whipsnake 

records are also associated strongly with 

chaparral or coastal scrub. Thus, soil 

type associated with multiple Alameda 

whipsnake records was considered a 

useful indicator of the presence of 

appropriate vegetation and rocky land 

or talus. 

Vegetation quality was evaluated by 

examining the distribution and pattern 

of the grassland and woodland 

vegetation types used by Alameda 

whipsnake. Two primary sources were 

used: (1) The GIS-based land-cover map 

for California (California GAP Analysis 

1998), and (2) visual inspection of 

digital aerial imagery from several 

sources. The visual inspection was 

necessary because the mapping unit for 

the GAP is relative large (i.e., 100 ha) 

and because of a somewhat restrictive 

GAP mapping criterion (designations 

reflect a dominant canopy species, i.e., 

greater than 20 percent). In some cases, 

vegetation very similar in appearance to 

chaparral could be seen in the aerials 

but was not reported as dominant in the 

GAP layer. Much smaller amounts of 

chaparral are likely to be distributed 

more widely, but could not be detected 

with either the GAP or aerial imagery 

layers. In general, habitat quality was 

deemed to be higher where all PCEs 

were present in abundance, and where 

the vegetation consisted of a more finely 

dissected mosaic. Additionally, areas 

which had chaparral were considered of 

greater importance because of the 

stronger association of snake records 

with this vegetation type. Quantitative 

limits for average patch dimension and/ 

or minimum amount of chaparral were 

not established due to the varying size 

of chaparral known to support the 

Alameda whipsnake. 

We also examined the digital imagery 

for roads, structures, cultivation, or 

other disturbances that would affect 

habitat quality for Alameda whipsnake. 

Some areas were not included as critical 

habitat because the level of such 

disturbance was determined to be high 

to support the Alameda whipsnake over 

time. 

Criteria Used To Identify Critical 

Habitat 

The criteria we utilized to designate 

critical habitat for Alameda whipsnake 

are based on the best scientific 

information available about the biology 

and ecology of the subspecies. In our 

determination of critical habitat for the 

Alameda whipsnake, we selected areas 

that possess the physical and biological 

features essential to the conservation of 

the subspecies and that may require 

special management considerations or 

protection. Application of these criteria 

(1) protects the best quality habitat in 

areas where Alameda whipsnake occurs; 

(2) maintains the current geographical, 

elevational, and ecological distribution 

of habitat and the subspecies, thereby 

preserving genetic variation within the 

range of the Alameda whipsnake, and 

minimizing the effects of local 

extinction; (3) minimizes fragmentation 

by establishing unit boundaries that 

would result in the lowest possible ratio 

of perimeter/unit area, maintaining the 

essential need for snake movement, 

dispersal, and interaction within the 

population. The specific habitat quality 

factors that we considered in 

determining critical habitat included 

soil type, vegetation type, vegetation 

mosaic, and degree of included 

development (e.g., roads, structures). 

There is no firm information on the 

actual population of Alameda 

whipsnake within its range. In addition, 

there has been no analysis of the 

minimum viable population size 

necessary to maintain a stable or 

increasing population of Alameda 

whipsnake. However, expert opinion is 

that the subspecies persists in relatively 

low numbers throughout its range 

(McGinnis 1992). Moreover, 

irretrievable loss of occupied Alameda 

whipsnake habitat due to recent urban 

development is significant in areas 

adjacent to several of the proposed 

critical habitat units. This development 

has likely resulted in a commensurate 

reduction in population size for the 

Alameda whipsnake. Accordingly, the 

general pattern of habitat loss and 

fragmentation was taken into 

consideration in the designation of 

critical habitat. 

Connectivity has been applied as a 

criterion to those areas where 

designation would result in a relatively 

high potential for dispersal between and 

within units. The need for special 

Federal Register / Vol. 70, No. 200 / Tuesday, October 18, 2005 / Proposed Rules 60613 

management considerations was applied 

where such management may be 

essential to enhance the connectivity or 

the integrity of high quality habitat 

within a unit. 

We are proposing to designate critical 

habitat on lands that we have 

determined are occupied at the time of 

listing and that contain the features 

found to be essential to the conservation 

of the Alameda whipsnake (PCEs). 

Within the boundaries of critical 

habitat, land that contains developed 

areas such as buildings, paved areas, 

and other structures has been excluded 

from this 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. We are 

proposing to exclude critical habitat 

from portions of Unit 4 based on the 

development of the draft East Contra 

Costa County HCP and lands within the 

East Bay Regional Park District. See 

Relationship of Critical Habitat to the 

Draft East Contra Costa County Habitat 

Conservation Plan (ECCHCP) below. 

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 

data available and to consider those 

physical and biological features (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. The specific 

PCEs essential for the conservation of 

the Alameda whipsnake are derived 

from the biological and ecological needs 

of the Alameda whipsnake as described 

in the Background section of this 

proposal and in previous listing and 

critical habitat rules for the species, as 

well as derived from the abiotic and 

biotic needs of the species as described 

below. 

The specific feeding and foraging 

habits of Alameda whipsnake are 

relatively well known (Stebbins 1985; 

Swaim 1994; Green 1998). Alameda 

whipsnake prey extensively on western 

fence lizards (Sceloporus occidentalis), 

but also have been known to prey on 

western skinks (Eumeces skiltonianus), 

as well as frogs, birds, and other snakes 

(Stebbins 1985; Swaim 1994). Its 

specialization on lizard prey and mode 

of foraging require areas that both 

support abundant prey populations and 

provide prey-viewing and capture 

opportunities. The Alameda whipsnake 

is most frequently recorded in close 

association with chaparral or scrub 

patches. These patches serve as the 

center of home ranges, and provide for 

concealment from predators and preyviewing opportunities while foraging. 

Snakes venture into adjacent grasslands 

or wooded habitats that exhibit, at a 

minimum, a partially open canopy. The 

open canopy character is believed to 

allow both development of the primary 

lizard prey base used by the snake, and 

efficient thermoregulation and foraging 

activities. The Alameda whipsnake 

hunts by sight, holding its head off the 

ground to peer over grass or rocks for 

potential prey capture opportunities. 

Essential features of Alameda 

whipsnake habitat must therefore 

include consideration of the habitat 

needs of the prey species and for prey 

captures. Such opportunities, as well as 

the prey base, are provided for by what 

is termed a ‘‘scrub community.’’ The 

particular arrangement of the landscape 

mosaic that supports Alameda 

whipsnake commonly consists of scrub 

patches within an open canopy of 

interspersed grasslands and rocklands, 

but may include closed or nearly closed 

scrub areas, including rocklands, and a 

much lower complement of grasses. 

Typical scrub communities within the 

range of the Alameda whipsnake 

include diablan sage scrub, coyote bush 

scrub, and chamise chaparral (Swaim 

1994), also classified as coastal scrub, 

mixed chaparral, and chamise-chaparral 

(Mayer and Laudenslayer 1998), and 

chamise, chamise-eastwood manzanita, 

chaparral whitethorn, and interior live 

oak shrub vegetation series as identified 

in the Manual of California Vegetation 

(Sawyer and Keeler-Wolf 1995), A 

Guide to Wildlife Habitats of California 

(Mayer and Laudenslayer 1988), and 

California Wildlife Habitat Relationship 

System (CDFG 1998). These vegetation 

series are characterized as being less 

than 20 ft (6 m) in height with sparse 

ground cover (the interior live oak shrub 

vegetation series having variable ground 

cover) and form a nearly continuous 

cover of closely spaced shrubs often 

with intertwining branches. Sufficient 

light penetrates through the canopy to 

support a herbaceous understory. The 

soils are usually nutrient poor and 

rocky, and stands are best developed on 

steep slopes. Because of complex 

patterns of topographic, edaphic, and 

climatic variations, these vegetation 

series form a mosaic pattern with 

inclusions of other vegetation series 

(blue oak, coast live oak, California Bay, 

California buckeye, California annual 

grassland) or open spaces. The 

percentage cover for these vegetation 

series is variable depending on species 

composition and aspect. Bare zones 

about 3 ft (1 m) wide may be 

interspersed within these vegetation 

series and extend around and out into 

adjacent vegetation series. These 

vegetation series occur on all slope 

aspects with patch sizes varying from 

square feet (meters) to square miles 

(kilometers) in dimension. The plant 

species associated with these vegetation 

series include, but are not limited to: 

chamise (Adenostoma sp.), manzanita 

(Artostaphylos sp.), Ceanothus sp., 

buckwheat (Eriogonum sp.), bush 

monkey flower (Diplacus sp.), toyon 

(Heteromeles arbutifolia), scrub oak 

(Quercus sp.), interior live oak (Q. 

wislizenii), canyon live oak (Q. 

chrysolepis), California coffeberry 

Rhamnus sp.), California buckeye 

(Aesculus californica), poison oak 

(Toxicodendron diversilobum), yerba 

santa (Eriodictyon californicum), and 

mountain mahogany (Cercocarpus sp.). 

Swaim (1994) found that core areas 

(i.e., areas of concentrated use by 

Alameda whipsnakes, based on 

telemetry and trapping data) were 

predominantly located on east, 

southeast, south, or southwest facing 

slopes and were characterized by open 

or partially-open canopy or grassland 

within 500 ft (150 m) of scrub. In early 

studies, Alameda whipsnakes were 

captured primarily where the canopy 

cover was open (less than 75 percent 

cover) or partially open (75 to 90 

percent cover). However, more recent 

trapping efforts have collected Alameda 

whipsnakes in scrub ranging from 

nearly complete or completely closed 

canopies, to very open canopies with a 

60614 Federal Register / Vol. 70, No. 200 / Tuesday, October 18, 2005 / Proposed Rules 

few patches of high quality scrub 

present (Swaim 2005b). These core areas 

provide sun-shade mosaics that offer an 

opportunity for the snake to achieve 

temperatures necessary for foraging, 

while providing retreat from predators 

(Swaim 1994). The open scrub habitat 

supports prey viewing opportunities, 

aiding foraging opportunities for this 

diurnal sight-hunting snake (Swaim 

1994). As previously mentioned, 

capture of spent females within scrub 

communities (Swaim 2002a) indicates 

scrub areas are in very close association 

with egg-laying sites, probably located 

in nearby grassland. Because they 

provide the primary foraging, breeding, 

and shelter areas for Alameda 

whipsnake, scrub communities are 

considered a PCE essential to the 

conservation of this subspecies. 

Although much of Alameda 

whipsnake activity occurs in scrub 

communities, other types of vegetation 

are also used for foraging and are 

necessary for normal behavior, breeding, 

reproduction, population interaction, 

and dispersal. Core areas used by the 

snake can be sustained by very small 

patches of scrub embedded within a 

larger mosaic of other dominant 

vegetation types (Swaim 2005b). Our 

review of available vegetation data and 

aerial imagery indicate that much of the 

distribution of Alameda whipsnake does 

not consist of large unbroken tracts of 

scrub community. The vegetation types 

adjacent to the scrub habitat that the 

Alameda whipsnake needs for foraging, 

dispersal, and population interactions 

include annual grassland, blue oakfoothill pine, blue oak woodland, 

coastal oak woodland, valley oak 

woodland, eucalyptus, redwood, and 

riparian communities (e.g. stream 

corridors). McGinnis (1992) has 

documented Alameda whipsnakes using 

oak woodland/grassland habitat as a 

corridor between stands of northern 

coastal scrub. 

Grassland habitats are used 

extensively by both sexes of Alameda 

whipsnake during the breeding season. 

Males used these areas most extensively 

during the spring mating season, 

possibly in search and selection of 

mates (Swaim 1994). Female use 

occurred after mating, possibly looking 

for egg laying sites or for dispersal to 

scrub habitat (Swaim 1994, Swaim 

2002a). Specifically, concentrated 

activity of gravid females, and hence the 

suspected location of egg laying sites, 

was in grassland areas with scattered 

shrubs within 10 to 20 ft (3 to 6 m) of 

true scrub habitat (Swaim 1994). 

Embedded within these scrub 

communities and adjacent habitats are 

areas consisting of rocky habitat (either 

rock outcrops or rock debris piles, 

known as ‘‘talus’’) and small rodent 

burrows; however, brush piles and deep 

soil crevices are also used by the snake 

(Swaim 1994). These areas are essential 

for normal behavior, breeding, 

reproduction, dispersal, and foraging 

because they provide shelter from 

predators, egg laying sites, over night 

retreats, and winter hibernacula (Swaim 

1994) and are associated with areas that 

have increased numbers of foraging 

opportunities (Stebbins 1985; Swaim 

1994). Swaim (1994) found rock 

outcrops were typically abundant in 

core areas and observed Alameda 

whipsnakes mating in these outcrops. 

During the mating season females 

remain near the retreat sites while males 

disperse throughout their home ranges 

(Swaim 1994). Hammerson (1979 in 

litt.) observed Alameda whipsnake 

emerging from burrows in the morning, 

basking in the sun, and retreating into 

burrows when the soil surface 

temperatures began to fall. Alameda 

whipsnakes retreat into winter 

hibernacula (e.g. rodent burrows, 

crevices between rocks) around 

November and emerge in March. 

Trapping of gravid females close to 

scrub communities in grassland with 

scattered shrubs (Swaim 1994) and 

spent females in true scrub communities 

(Swaim 2002a) suggests that rock 

outcrops, talus, and burrows (mating 

habitats) need to be relatively close to 

scrub and nearby grassland habitat 

(suspected egg laying habitats). 

Dispersal habitats are essential for the 

conservation of Alameda whipsnake. 

Protecting the ability of Alameda 

whipsnake to move freely across the 

landscape in search of habitats is 

essential for: (1) Sustaining populations 

by providing opportunity for movement 

and establishment of home ranges by 

juvenile recruits, (2) maintaining gene 

flow by the movement of both juveniles 

and adults between subpopulations, and 

(3) allowing recolonization of habitat 

after fires or other natural events that 

have resulted in local extirpations. The 

available information on movements of 

other colubrid snakes is limited to a 

small minority of species, but indicates 

a general potential for significant 

mobility. Loughheed et al. (1999) found 

evidence of substantial genetic exchange 

among local hibernacula greater than 

3.75 miles (6 km) apart, although gene 

flow over distances of 6.25 miles (10 

km) and greater appears to be 

substantially less. Based on extensive 

radio-tracking data, Blouin-Demers and 

Weatherhead (2002) found that male 

and female ratsnake (Elaphe obsolete) (a 

species similar in size and 

characteristics to the Alameda 

whipsnake) travel up to 5 miles (8 km) 

from hibernacula to mate. Therefore, it 

is likely that medium-sized species of 

this group, such as the Alameda 

whipsnake, move between areas up to a 

few miles apart. This is consistent with 

the distribution of vegetation types in 

portions of the Alameda whipsnake 

range, where the vegetation often has 

more dense closed canopy on the 

northeast-facing slopes, and less dense 

open canopy on southwest-facing 

slopes. Very recent trapping data has 

shown several instances of snakes 

residing in and moving through 

predominantly north-facing slopes in 

two of the six proposed units (Swaim 

2005c, Swaim 2005d). Habitat with a 

more open canopy would provide the 

greatest range of essential functions. 

However closed-canopy areas are 

considered essential because they 

provide avenues of dispersal and 

interaction between sub-populations, 

and movement through such closedcanopy areas has been documented 

(Swaim 2002b). 

Additional trapping data has shown 

the maximum distance between 

Alameda whipsnake observations from 

the nearest scrub is much larger, up to 

4.5 miles (7.3 km), than either the home 

range diameter or average movements, 

suggesting more extensive use of 

grassland for either foraging or corridor 

movement (Swaim 2000; Swaim 2003; 

Swaim 2005b). The scale of these 

grassland patches is on the order of 

several miles (kilometers) across, and 

movement of this degree would permit 

Alameda whipsnakes to disperse to 

other adjacent habitat. Large blocks of 

contiguous habitat, relatively 

uninterrupted by roads, structures, or 

other development, fulfills the essential 

need for interchange and interaction 

among individuals and subpopulations 

within the limited distribution of 

Alameda whipsnake. Thus, other 

vegetation (e.g., annual grassland, blue 

oak-foothill pine, blue oak woodland, 

coastal oak woodland, valley oak 

woodland, eucalyptus, redwood, and 

riparian communities) adjacent to scrub 

habitat is considered a feature essential 

to the conservation of the Alameda 

whipsnake. 

The characteristics and composition 

of the vegetation series adjacent to scrub 

or rocky habitats which are used by 

Alameda whipsnake for foraging, short 

and long distant dispersal, and mating 

can be variable depending on location, 

topography, soils, and rainfall. The 

woodland vegetation series are 

comprised of slow growing, long-lived 

deciduous and evergreen trees 15 to 70 

ft (4 to 21 m) tall with a mixed 

Federal Register / Vol. 70, No. 200 / Tuesday, October 18, 2005 / Proposed Rules 60615 

understory of grass and herbaceous 

vegetation or shrub vegetation. Some 

common species associated with the 

woodland vegetation series include: 

blue oak (Quercus douglassi), valley oak 

(Quercus lobata), canyon live oak, 

California black oak (Quercus kellogi), 

interior live oak, madrone (Arbutus 

menziesii), foothill pine (Pinus 

sabatiana), California bay, California 

buckeye, coyote brush, manzanita, 

gooseberry (Ribes sp.), redwood 

(Sequoia sempervirens), and Eucalyptus 

sp. Some common species associated 

with the California annual grassland 

vegetation series include: wild oats 

(Avena sp.), soft chess (Bromus mollis), 

brome sp., barley (Hordeum sp.), and 

fescue (Festuca sp.). Some remnant 

perennial grasses may also be 

distributed within this grassland 

vegetation series comprised of species 

such as needlegrass (Nassella sp.), 

California onion grass (Melica 

californica), and California fescue 

(Festuca californica). Herbaceous 

vegetation within the woodland and 

grassland vegetation series includes 

filaree sp., turkey mullein (Eremocarpus 

sp.), popcorn flower (Plagiobothrys sp.), 

and California poppy (Eschscholtzia 

california). 

Primary Constituent Elements for the 

Alameda Whipsnake 

Based on our current knowledge of 

the life history, biology, and ecology of 

the Alameda whipsnake and the 

requirements of the habitat necessary to 

sustain the essential life history 

functions of the subspecies, we have 

determined that the primary constituent 

elements for the Alameda whipsnake 

are: 

(1) Scrub/shrub communities with a 

mosaic of open and closed canopy: 

Scrub/shrub vegetation dominated by 

low to medium-stature woody shrubs 

with a mosaic of open and closed 

canopy as characterized by the chamise, 

chamise-eastwood manzanita, chaparral 

whitethorn, and interior live oak shrub 

vegetation series as identified in the 

Manual of California Vegetation (Sawyer 

and Keeler-Wolf 1995), A Guide to 

Wildlife Habitats of California (Mayer 

and Laudenslayer 1988), and California 

Wildlife Habitat Relationship System 

(CDFG 1998), occurring at elevations 

from sea level to approximately 3,850 ft 

(1,170 m). Such scrub/shrub vegetation 

within these series form a pattern of 

open and closed canopy which is used 

by the Alameda whipsnake to provide 

shelter from predators, temperature 

regulation by providing sunny and 

shady locations, prey-viewing 

opportunities, and nesting habitat and 

substrate. These features contribute to 

support a prey base consisting of 

western fence lizards and other prey 

species such as skinks, frogs, snakes, 

and birds. 

(2) Woodland or annual grassland 

plant communities contiguous to lands 

containing PCE 1: Woodland or annual 

grassland vegetation series comprised of 

one or more of the following: blue oak, 

coast live oak (Quercus sp.), California 

bay (Umbellularia californica), 

California buckeye, and California 

annual grassland vegetation series (as 

identified in the Manual of California 

Vegetation (Sawyer and Keeler-Wolf 

1995), A Guide to Wildlife Habitats of 

California (Mayer and Laudenslayer 

1988), and California Wildlife Habitat 

Relationship System (CDFG 1998)) are 

PCE 2. This mosaic of vegetation 

supports a prey base consisting of 

western fence lizards and other prey 

species such as skinks, frogs, snakes, 

and birds and provides opportunities 

for: (1) Foraging by allowing snakes to 

come in contact with and visualize, 

track, and capture prey (especially 

western fence lizards along with other 

prey such as skinks, frogs, birds); (2) 

short and long distance dispersal 

within, between, or to adjacent to areas 

containing essential features (i.e., PCE 1 

or PCE 3); and (3) contact with other 

Alameda whipsnakes for mating and 

reproduction. 

(3) Lands containing rock outcrops, 

talus, and small mammal burrows. 

These areas are used for retreats 

(shelter), hibernacula, foraging, 

dispersal, and provide additional prey 

population support functions. 

Special Management Considerations or 

Protections 

When designating critical habitat, we 

assess whether the features essential to 

the conservation of the whipsnake that 

have been identified as PCEs that may 

require special management 

considerations or protections. Special 

management is required when threats to 

the species and features essential to its 

conservation exist and must be reduced 

by management to conserve the species. 

The greatest threat to all six units is 

continued urban development, which 

destroys and fragments the features 

essential to the conservation of the 

subspecies and thus the habitat used by 

the Alameda whipsnake. Second, 

fragmentation and destruction of 

features essential to the conservation of 

the subspecies and thus the habitat also 

results from road development and 

widening in all six units. Third, the 

features essential to the conservation of 

the subspecies are threatened directly 

and indirectly by the effects of fire 

suppression. Fire suppression 

exacerbates the effects of wildfires 

through the buildup of fuel (i.e., 

underbrush and woody debris), creating 

conditions for slow-moving, hot fires 

that completely burn all sources of 

cover for the Alameda whipsnake. 

Highest intensity fires occur in the 

summer and early fall, when 

accumulated fuel is abundant and dry. 

During this period, hatchling and adult 

Alameda whipsnakes are aboveground 

(Swaim 1994), resulting in populations 

being more likely to sustain heavy 

losses from fires. Fire suppression has 

led to the encroachment of nonindigenous and ornamental trees into 

grassland habitats, further increasing 

flammable fuel loads in and around 

Alameda whipsnake habitat. Fire 

suppression has also lead to the change 

of scrub communities from open/closed 

mosaics to closed canopy stands. As 

described above, Alameda whipsnakes 

prefer scrub communities consisting of 

an open/closed mosaic. The closed 

scrub canopy also results in a buildup 

of flammable fuels over time (Parker 

1987). Special management would be 

required to properly manage fuel load 

and prevent catastrophic fire within the 

six units. 

Finally, the features essential to the 

conservation of the subspecies and thus 

the habitat within all six units are 

subject to increased predatory pressure 

from introduced species, such as rats 

(Rattus spp.), feral pigs (Sus scrofa), and 

feral and domestic cats (Felis domestica) 

and dogs (Canis familiaris). These 

additional threats become particularly 

acute where urban development 

immediately abuts Alameda whipsnake 

habitat. A growing movement to 

maintain feral cats in parklands is an 

additional potential threat to the 

Alameda whipsnake. The East Bay 

Regional Park District (EBRP) is 

currently facing public pressure to allow 

private individuals to maintain feral 

cats on park lands (DelVecchio 1997). 

Although the actual impact of predation 

under such situations has not been 

studied, feral cats are known to prey on 

reptiles, including yellow racers 

(Coluber sp. (Hubbs 1951)), a fast, 

diurnal snake closely related to the 

Alameda whipsnake (Stebbins 1985). 

Alameda whipsnakes may be adversely 

affected in areas that lie adjacent to 

urban development because of the 

associated loss of cover habitats in 

combination with increased native and 

nonnative predators using these areas. 

Special management of nonnative 

predators would be required within all 

six units.

Proposed Critical Habitat Designation 

We are proposing six units as critical 

habitat for the Alameda whipsnake. The 

critical habitat areas described below 

constitute our assessment of areas that 

have been determined to be occupied at 

the time of listing, that contain the 

PCEs, and that may require special 

management. The six areas proposed for 

designation as critical habitat for the 

Alameda whipsnake are described 

below. 

Table 1 below provides the 

approximate area (ac/ha) determined to 

be essential to the Alameda whipsnake 

and the area proposed for exclusion 

from the final critical habitat 

designation by unit.

We present brief descriptions of all 

units, and reasons why they are 

essential for the conservation of the 

Alameda whipsnake below. 

Unit 1: Tilden-Briones; Alameda and 

Contra Costa Counties (34,119 ac 

(13,808 ha)) 

Unit 1 is bordered approximately by 

State Highway 4 and the cities of Pinole, 

Hercules, and Martinez to the north; by 

State Highway 24 and the City of Orinda 

Village to the south; Interstate 80, and 

the cities of Berkeley, El Cerrito, and 

Richmond, to the west; and Interstate 

680 and the City of Pleasant Hill to the 

east. Unit 1 is connected to Unit 6 to the 

south. Land ownership within the 

proposed unit includes approximately 

8,108 ac (3,281 ha) of East Bay Regional 

Park (EBRP) lands with the remainder of 

land being privately owned. We propose 

to exclude from critical habitat a portion 

of the East Bay Regional Park from this 

unit (see section ‘‘Relationship of 

Critical Habitat to the East Bay Regional 

Park—Exclusion Under Section 4(b)(2)’’

below). 

The unit contains a complex mosaic 

pattern of grassland with woody scrub 

vegetation of several types (PCE 1 and 

PCE 2) as well as rock outcrops or other 

talus features (PCE 3) which are 

uniformly distributed throughout the 

unit with little habitat fragmentation. 

Alameda whipsnake records occur 

within the unit and are also uniformly 

distributed with the dates of Alameda 

whipsnake records spanning a time 

period ranging from before the 

subspecies’ listing to after the time of 

listing (1986-present). Very limited 

development or habitat fragmentation is 

present, with the exception of a few 

structures presumably associated with 

livestock management. The distribution 

of essential features throughout the unit 

allows Alameda whipsnake populations 

to utilize and freely disperse within the 

unit, making the overall population less 

vulnerable to local extinction which 

could result from fire, landslide, or 

some other natural event (e.g. drought, 

disease). The unit is included in 

proposed critical habitat because it 

contains features essential to the 

conservation of the Alameda 

whipsnake, it is occupied, and 

represents the northwestern portion of 

the subspecies range and one of five 

population centers. The special 

management actions which may be 

required within the unit include 

Federal Register / Vol. 70, No. 200 / Tuesday, October 18, 2005 / Proposed Rules 60617 

prescribed burns, and management of 

grazing activities to maintain a mosaic 

of open habitat. Additional special 

management which may be required for 

this unit includes management of 

trespass, unauthorized trail 

construction, dumping, feral animal 

control and other activities associated 

with urban interface. 

Unit 2: Oakland–Las Trampas; Contra 

Costa and Alameda Counties (24,524 ac 

(9,925 ha)) 

Unit 2 is located south of State Route 

24, north of Interstate 580, east of State 

Route 13, and west of Interstate 680 and 

the cities of Danville, San Ramon, and 

Dublin. Unit 2 is connected to Unit 6 to 

the north. Land ownership includes 

4,408 ac (1,784 ha) of East Bay Regional 

Park and East Bay Municipal Utilities 

District (EBMUD) lands with the 

remainder of lands being privately 

owned. We propose to exclude from 

critical habitat a portion of the East Bay 

Regional Park from this unit (see section 

‘‘Relationship of Critical Habitat to the 

East Bay Regional Park—Exclusion 

Under Section 4(b)(2)’’ below). 

Unit 2 contains a range of vegetation 

(PCE 1 and PCE 2), soil types, and rocky 

features (PCE 3) essential to the 

conservation of the subspecies, supports 

viable Alameda whipsnake populations, 

and has minimal development such as 

roads and structures. Areas with 

development or reduced soil and 

vegetation characteristics were not 

included as proposed critical habitat for 

this unit. Essential features within Unit 

2 which contain denser woodland 

habitat may be subject to special 

management considerations, such as 

prescribed burns, to improve the habitat 

quality and enhance the potential for 

Alameda whipsnake movement between 

units. Additional special management 

which may be required throughout this 

unit includes management of trespass, 

unauthorized trail construction, 

dumping, feral animal control and other 

activities associated with urban 

interface. Alameda whipsnake records 

have been documented by multiple 

records within the unit as well as 

adjacent to the unit. Dispersal between 

Units 2 and 1 occurs directly through 

Unit 6, and impediments to such 

movement do not appear to be present. 

Unit 2 is included in the proposed 

critical habitat because it contains 

features essential to the conservation of 

the Alameda whipsnake, it is occupied 

by the subspecies, and represents the 

central distribution of Alameda 

whipsnake and one of the five 

population centers. 

Unit 3: Hayward–Pleasanton Ridge; 

Alameda County (27,551 ac (11,149 ha)) 

Unit 3 is generally located 

immediately to the west of Interstate 

680 and to the south of Interstate 580. 

Land ownership includes 404 ac (164 

ha) of East Bay Regional Park with the 

remainder of lands being privately 

owned. We propose to exclude from 

critical habitat a portion of the East Bay 

Regional Park from this unit (see section 

‘‘Relationship of Critical Habitat to the 

East Bay Regional Park—Exclusion 

Under Section 4(b)(2)’’ below). 

Unit 3 contains the mosaic of scrub 

and chaparral vegetation and rocky 

outcrops considered as essential 

features (PCE 1). The unit also includes 

a variation in vegetation patch size, 

abundant edge between grassland and 

woodland, and minimal amount of 

development or planned development. 

The soils present are considered 

supportive of the scrub and rock 

outcrop features essential for Alameda 

whipsnake. The Alameda whipsnake 

records within this unit are associated 

with Gaviota rocky sandy loams in 

particular, which likely provide talus 

(PCE 3) and appear to coincide in aerial 

imagery to scrub or chaparral vegetation 

preferred by Alameda whipsnake. 

Vegetation is largely woodland of 

variable densities (PCE 2) and statures 

(trees, shrubs) interspersed with 

grassland. Some peripheral portions of 

habitat around this unit were not 

included as proposed critical habitat 

due to the high degree of developmentrelated disturbance and fragmentation of 

the habitat. The unit is included in 

proposed critical habitat because it 

contains features essential to the 

conservation of the Alameda 

whipsnake, it is occupied by the 

subspecies, and represents the 

southwestern portion of the subspecies 

range and one of the five population 

centers. The special management which 

may be required throughout this unit 

includes management of controlled 

burns and grazing, trespass, 

unauthorized trail and road 

construction, dumping, feral animal 

control and other activities associated 

with urban or recreational interface. 

Unit 4: Mount Diablo–Black Hills; 

Contra Costa and Alameda counties 

(69,598 ac (28,165 ha)) 

This unit encompasses Mount Diablo 

State Park and surrounding lands, and 

is largely within Contra Costa County 

except a small portion that lies in 

Alameda County. Lands are owned by 

the Bureau of Land Management (61 ac 

(25 ha)), State Department of Parks and 

Recreation (13,874 ac (5,615 ha)), East 

Bay Regional Park (3,641 ac (1,475 ha)), 

and private landowners (52,022 ac 

(21,053 ha)). 

Numerous Alameda whipsnake 

observations (i.e., greater than 50 

records from 1972 to present) occur 

throughout the unit, many of which are 

associated with dense rock outcrops 

(PCE 3) and chaparral, scrub, and oak 

woodland (PCE 1, PCE 2). The pattern 

of woody vegetation with grassland and 

rock outcrops forms an intricate 

landscape mosaic that is highly 

functional habitat for the Alameda 

whipsnake. The vegetation and soil 

characteristics, the mosaic habitat 

pattern, the abundance of Alameda 

whipsnake records, and the lack of 

surrounding development and relative 

absence of roadways, together indicate 

that this unit likely provides some of the 

very highest quality and largest 

contiguous blocks of habitat within the 

range of the subspecies, as well as some 

of its most robust populations. Special 

management, such as prescribed burns, 

may be required for portions of the unit 

with dense vegetation. Special 

management required throughout this 

unit includes management of grazing, 

trespass, unauthorized trail and road 

construction, dumping, feral animal 

control and other activities associated 

with urban or recreational interface. The 

unit is included in proposed critical 

habitat because it contains features 

essential to the conservation of the 

Alameda whipsnake, is occupied by the 

subspecies, and represents the 

northeastern portion of the subspecies 

range and one of the five population 

centers. We propose to exclude from 

critical habitat a portion of the East Bay 

Regional Park from this unit (see section 

‘‘Relationship of Critical Habitat to the 

East Bay Regional Park—Exclusion 

Under Section 4(b)(2)’’ below). 

Unit 5A: Cedar Mountain; Alameda and 

San Joaquin Counties (24,723 ac (10,005 

ha)) 

The unit is generally located east of 

Lake Del Valle along Cedar Mountain 

Ridge and Crane Ridge to Corral Hollow 

west of Interstate 580. Land ownership 

within the proposed unit includes 

approximately 2,492 ac (1,009 ha) of 

Department of Energy land and 246 ac 

(99 ha) of East Bay Regional Park. Lands 

within the remainder of the unit are 

privately owned. 

The vegetation pattern within this 

unit consists of dominance by various 

woodland, scrub, and/or chaparral 

communities on northeast-facing slopes 

(PCE 1, PCE 2). More open, grasslanddominated communities are prominent 

on southwest-facing slopes, but there is 

also a significant component of 

60618 Federal Register / Vol. 70, No. 200 / Tuesday, October 18, 2005 / Proposed Rules 

woodland habitat on these slopes. 

Significant areas of vegetation types 

known to support Alameda whipsnake 

are present, including coastal oak, 

chamise-chaparral, mixed chaparral, 

blue-oak-foothill pine woodland, blue 

oak woodland, valley oak woodland, 

and montane hardwood. In most 

instances, the proposed boundaries for 

critical habitat designation correspond 

to natural breaks in plant communities 

and soil quality, and/or landform 

(ridgelines, water features). A moderate 

number of light roads are present within 

the unit, although there are very few 

structures or other land modifications. 

Special management, such as prescribed 

burns, may be required for portions of 

the unit with dense vegetation. The 

special management which may be 

required throughout this unit includes 

management of grazing, trespass, 

unauthorized trail and road 

construction, dumping, feral animal 

control and other activities associated 

with urban or recreational interface. The 

unit is included in proposed critical 

habitat because it contains features 

essential to the conservation of the 

Alameda whipsnake, it is occupied by 

the subspecies, and represents the 

southern and eastern most distribution 

of Alameda whipsnake and one of five 

population centers for the subspecies. 

We propose to exclude from critical 

habitat a portion of the East Bay 

Regional Park from this unit (see section 

‘‘Relationship of Critical Habitat to the 

East Bay Regional Park—Exclusion 

Under Section 4(b)(2)’’ below). 

Unit 5B: Alameda Creek; Alameda and 

Santa Clara Counties (18,214 ac (7,371 

ha)) 

This unit is located northeast of 

Calaveras Reservoir, south of the town 

of Sunol including the area along 

Wauhab Ridge in Alameda County and 

Oak Ridge in Santa Clara County. 

Alameda Creek is located at the west 

margin of the unit, and the unit contains 

the Sunol Regional Wilderness and 

Camp Ohlone Regional Park 

(approximately 361 ac (146 ha)) which 

are managed by the East Bay Regional 

Park. Vegetation is a mix of blue oakfoothill pine and annual grassland with 

a significant amount of woodland 

patches. Coastal live oak is present in 

the vicinity of Lleyden Creek. Soil types 

in which Alameda whipsnakes are 

found dominate the unit. This subunit 

contains six Alameda whipsnake 

records documented between 1972 and 

2000. Significant areas of vegetation 

types know to support Alameda 

whipsnake are present, including 

coastal oak, chamise-chaparral, mixed 

chaparral, blue-oak-foothill pine 

woodland, blue oak woodland, valley 

oak woodland, and montane hardwood 

interspersed with rock outcrops or talus 

(PCEs 1, 2, 3). The proposed boundaries 

for critical habitat designation 

correspond to natural breaks in plant 

communities, soil type, and or 

landform. A moderate number of light 

roads are present within the unit, 

although there are very few structures or 

other land modifications. Development 

pressure within or adjacent to the unit 

is small, as a result the survey efforts for 

the Alameda whipsnake have also not 

been as extensive as in the other 

proposed units. Special management, 

such as prescribed burns, may be 

required for portions of the unit with 

dense vegetation. The special 

management which may be required 

throughout this unit includes 

management of grazing, trespass, 

unauthorized trail and road 

construction, dumping, feral animal 

control and other activities associated 

with urban or recreational interface. The 

unit is included in proposed critical 

habitat because it contains features 

essential to the conservation of the 

Alameda whipsnake, it is occupied, and 

represents the southern most 

distribution of Alameda whipsnake and 

one of the five population centers for 

the subspecies. We propose to exclude 

from critical habitat a portion of the East 

Bay Regional Park from this unit (see 

section ‘‘Relationship of Critical Habitat 

to the East Bay Regional Park—

Exclusion Under Section 4(b)(2)’’

below). 

Unit 6: Caldecott Tunnel; Contra Costa 

and Alameda Counties (4,612 ac (1,867 

ha)) 

This proposed critical habitat unit lies 

between Units 1 and 2, along the 

Alameda and Contra Cost County line. 

Land ownership within this unit 

includes 272 ac (110 ha) of East Bay 

Regional Park lands with the remainder 

of lands being privately owned. We 

propose to exclude from critical habitat 

a portion of the East Bay Regional Park 

from this unit (see section ‘‘Relationship 

of Critical Habitat to the East Bay 

Regional Park—Exclusion Under 

Section 4(b)(2)’’ below). 

The unit is bounded by dense urban 

development to the east and west. 

However, the vegetation and soil types 

that are known to support Alameda 

whipsnake are dominant throughout the 

unit (PCEs 1, 2, 3). About eight Alameda 

whipsnake records are known from the 

unit between 1990 and 2002. Special 

management considerations may be 

warranted to consolidate existing roads 

or limit additional road construction in 

order to preserve a corridor function in 

this unit as a consequence of the 

restricted width of the unit and the 

current presence of a moderate number 

of roads. Prescribed burns may also be 

required to maintain the habitat mosaic 

considered essential. The unit is 

included in proposed critical habitat 

because it contains features essential to 

the conservation of the Alameda 

whipsnake, it is occupied, and 

represents the last remaining habitat 

connecting two of the five population 

centers for the subspecies. Maintaining 

connectivity between units allows for 

dispersal between units for the 

subspecies and allows for genetic 

exchange between two of the five 

population centers for the Alameda 

whipsnake. 

Effects of Critical Habitat Designation 

Section 7 Consultation 

Section 7 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 402.2, 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.’’ We are currently 

reviewing the regulatory definition of 

adverse modification in relation to the 

conservation of the subspecies. 

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. 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 

Federal Register / Vol. 70, No. 200 / Tuesday, October 18, 2005 / Proposed Rules 60619 

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)). 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, the 

action agency ensures that their 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. 

Federal activities that may affect 

Alameda whipsnakes or their 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 U.S. Army Corps of Engineers 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 non-Federal and private 

lands that are not federally funded, 

authorized, or permitted do not require 

section 7 consultation. 

Each of the specific areas designated 

in this rule as critical habitat for the 

Alameda whipsnake have been 

determined to contain sufficient PCEs to 

provide for one or more of the life 

history functions for the whipsnake. In 

some cases, the PCEs exist as a result of 

ongoing Federal actions. As a result, 

ongoing Federal actions at the time of 

designation will be included in the 

baseline in any consultation pursuant to 

section 7 of the Act conducted 

subsequent to this designation. 

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 

or adversely modify critical habitat may 

also jeopardize the continued existence 

of the Alameda whipsnake. Federal 

activities that, when carried out, may 

adversely affect critical habitat for the 

Alameda whipsnake include, but are not 

limited to: 

(1) Actions that would result in 

altered or degraded chaparral scrub or 

oak woodland communities. Such 

activities could include, but are not 

limited to, urban development, 

unmanaged fire suppression activities, 

and livestock overgrazing. These 

activities could eliminate or reduce the 

habitat essential for reproduction, 

growth, or shelter of Alameda 

whipsnake. 

(2) Actions that would result in 

complete loss of habitat or impediments 

to migration by development of partial 

or complete barriers through habitat 

areas. These activities are most often 

funded or permitted by the Federal 

Highway Administration or the State 

highway system, or involve licensing of 

construction for communication sites by 

the Federal Communications 

Commission. Such activities could 

include, but are not limited to, new road 

construction, right-of-way designation, 

routine maintenance and operation of 

existing roads, or installation of new 

radio equipment and facilities. These 

activities could eliminate foraging, 

resting, or denning habitat, as well as 

reduce movement corridors essential for 

reproduction, sheltering, or growth of 

Alameda whipsnake. Such activities 

could also lead to increased road kill 

incidences for the subspecies. 

(3) Actions that result in a discharge 

of dredged or fill material into waters of 

the United States by the Army Corps 

under section 404 of the Clean Water 

Act. Such activities could include, but 

are not limited to, placement of fill into 

wetlands or channelization of stream 

corridors. These activities could 

eliminate or reduce the habitat essential 

for the reproduction, feeding, or growth 

of Alameda whipsnake. 

All six proposed critical habitat units 

are occupied by the subspecies at the 

time of listing due to documented 

records of Alameda whipsnakes in those 

units. All lands proposed for critical 

habitat designation are within the 

historical geographical area occupied by 

the subspecies, and are likely to be used 

by the Alameda whipsnake whether for 

foraging, breeding, growth of juveniles, 

dispersal, migration, genetic exchange, 

or sheltering. We consider all units 

included in this proposed designation to 

include features essential to the 

conservation of the Alameda 

whipsnake. 

Application of Sections 3(5)(A) and 

4(a)(3) and Exclusions Under Section 

4(b)(2) of the Act 

We are not proposing to exempt any 

lands from critical habitat pursuant to 

section 4(a)(3) of the Act. 

Section 4(b)(2) of the Act states that 

critical habitat shall be designated, and 

revised, on the basis of the best 

available scientific data after taking into 

consideration the economic impact, 

national security impact, and any other 

relevant impact of specifying any 

particular area as critical habitat. An 

area may be excluded from critical 

habitat if it is determined that the 

benefits of exclusion outweigh the 

benefits of specifying a particular area 

as critical habitat, unless the failure to 

designate such area as critical habitat 

will result in the extinction of the 

species. 

In our critical habitat designations, we 

use both the provisions outlined in 

sections 3(5)(A) and 4(b)(2) of the Act to 

evaluate those specific areas that we 

consider proposing to designate as 

critical habitat. Lands we have found 

that do not meet the definition of 

critical habitat under section 3(5)(A) or 

have excluded pursuant to section 

60620 Federal Register / Vol. 70, No. 200 / Tuesday, October 18, 2005 / Proposed Rules 

4(b)(2) include those covered by the 

following types of plans if they provide 

assurances that the conservation 

measures they outline will be 

implemented and effective: (1) 

Endangered Species Management Plans 

prepared by the DOD (where a 4(a)(3) 

exemption is not possible due to a 

unsigned Integrated Natural Resource 

Management Plan (INRMP)); (2) legally 

operative HCPs that cover the 

subspecies and provide assurances that 

the conservation measures for the 

subspecies will be implemented and 

effective; (3) draft HCPs that cover the 

subspecies, have undergone public 

review and comment, and provide 

assurances that the conservation 

measures for the subspecies will be 

implemented and effective (i.e., pending 

HCPs); (4) Tribal conservation plans/ 

programs that cover the subspecies and 

provide assurances that the 

conservation measures for the 

subspecies will be implemented and 

effective; (5) State conservation plans/ 

programs that provide assurances that 

the conservation measures for the 

subspecies will be implemented and 

effective; (6) National Wildlife Refuges 

with Comprehensive Conservation Plans 

(CCPs) or programs that provide 

assurances that the conservation 

measures for the subspecies will be 

implemented and effective; and (7) 

Partnerships, conservation plans/ 

easements, or other type of formalized 

relationship/agreement on private lands 

where a conservation plan or program 

provide assurances that the 

conservation measures for the 

subspecies will be implemented and 

effective. 

Relationship of Critical Habitat to 

Habitat Conservation Plan Lands—

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

Act 

Section 4(b)(2) of the Act requires us 

to consider other relevant impacts, in 

addition to economic impacts, when 

designating critical habitat. Section 

10(a)(1)(B) of the Act authorizes us to 

issue permits for the take of listed 

wildlife species incidental to otherwise 

lawful activities. Development of an 

HCP is a prerequisite for the issuance of 

an incidental take permit pursuant to 

section 10(a)(1)(B) of the Act. An 

incidental take permit application must 

be supported by an HCP that identifies 

conservation measures that the 

permittee agrees to implement for the 

species to minimize and mitigate the 

impacts of the permitted incidental take. 

HCPs vary in size and may provide for 

incidental take coverage and 

conservation management for one or 

many Federally-listed species. 

Additionally, more than one applicant 

may participate in the development and 

implementation of an HCP. Large 

regional HCPs expand upon the basic 

requirements set forth in section 

10(a)(1)(B) of the Act because they 

reflect a voluntary, cooperative 

approach to large-scale habitat and 

species conservation planning. Many of 

the large regional HCPs in southern 

California have been, or are being, 

developed to provide for the 

conservation of numerous Federallylisted species and unlisted sensitive 

species and the habitat that provides for 

their biological needs. These HCPs are 

designed to proactively implement 

conservation actions to address future 

projects that are anticipated to occur 

within the planning area of the HCP. 

However, given the broad scope of these 

regional HCPs, not all projects 

envisioned to potentially occur may 

actually take place. The State of 

California also has a NCCP process that 

is very similar to the Federal HCP 

process and is often completed in 

conjunction with the HCP process. We 

recognize that many of the projects with 

HCPs also have State-issued NCCPs. In 

the case of approved regional HCPs and 

accompanying Implementing 

Agreements (IAs) (e.g., those sponsored 

by cities, counties, or other local 

jurisdictions) that provide for incidental 

take coverage, a primary goal of these 

regional plans is to provide for the 

protection and management of habitat 

essential for species conservation, while 

directing development to other areas. 

We are considering excluding lands 

within the Draft East Contra Costa 

County HCP from the designation of 

critical habitat for the Alameda 

whipsnake pursuant to section 4(b)(2) of 

the Act. This draft HCP includes lands 

within a portion of proposed critical 

habitat Unit 4. We believe the benefits 

of excluding lands within this draft HCP 

from the final critical habitat 

designation outweigh the benefits of 

including them and seeking public 

comment on this proposed exclusion. 

The following represents our rationale 

for excluding this area. 

Draft East Contra Costa County Habitat 

Conservation Plan (ECCHCP) 

The draft ECCHCP is currently under 

review and open for public comment 

until December 1, 2005. The document 

is available at the following Web site: 

http://www.cocohcp.org. The document 

will also be available for public 

inspection, by appointment, during 

normal business hours at the 

Sacramento Fish and Wildlife Office 

[see ADDRESSES]. 

We expect a finalized plan before the 

end of 2006. Participants in the draft 

ECCHCP include the County of Contra 

Costa; the cities of Brentwood, Clayton, 

Oakley, and Pittsburg, California; the 

Contra Costa Water District; and the East 

Bay Regional Park District. The draft 

ECCHCP encompasses the eastern 

portion of Contra Costa County from 

approximately west of Concord to Sand 

Mound Slough and Clifton Court 

Forebay on the east. The draft ECCHCP 

is also a subregional plan under the 

State’s Natural Community 

Conservation Planning (NCCP) process 

and was developed in cooperation with 

the California Department of Fish and 

Game. The draft ECCHCP identifies the 

Alameda whipsnake as a covered 

species and has identified areas where 

growth and development are expected 

to occur, as well as several conservation 

measures, including: (1) Preserving 

between 12,254 to 13,983 ac (4,959 to 

5,659 ha) of Alameda whipsnake 

habitat; (2) preserving major habitat 

connections linking existing public 

lands; (3) incorporating a range of 

habitat and population management and 

enhancement measures including 

monitoring, prescribed burning, and 

recreational use controls; (4) fully 

mitigating the impacts to covered 

species; (5) maintaining ecosystem 

processes; and (6) contributing to the 

recovery of covered species. When the 

conservation measures are implemented 

they will benefit Alameda whipsnake 

conservation by preserving and 

restoring existing core area and upland 

movement habitat for the species. We 

expect that the draft ECCHCP will 

provide substantial protection for all 

three of the primary constituent 

elements for the Alameda whipsnake, 

and that protected lands will receive the 

special management they require 

through funding mechanisms that will 

be implemented under the ECCHCP. 

(1) Benefits of Inclusion 

The primary benefit to designation of 

critical habitat is the requirement that 

Federal agencies consult with the 

Service under section 7 of the Act to 

ensure that their actions are not likely 

to result in the destruction or adverse 

modification of critical habitat. If 

critical habitat were designated in these 

areas, primary constituent elements in 

these areas would be protected from 

destruction or adverse modification by 

Federal actions using a conservation 

standard based on the Ninth Circuit’s 

decision in Gifford Pinchot. This 

requirement would be in addition to the 

requirement that proposed Federal 

actions would not be likely to 

jeopardize the species’ continued 

Federal Register / Vol. 70, No. 200 / Tuesday, October 18, 2005 / Proposed Rules 60621 

existence. However, inasmuch as these 

areas are currently occupied by the 

species, consultation for activities that 

might adversely impact the species, 

including habitat modification (see 

definition of ‘‘harm’’ at 50 CFR 17.3), 

would be required even without the 

critical habitat designation. Because 

habitat modification is considered 

under the jeopardy analysis, we believe 

the benefits of habitat protection from 

critical habitat is now small to 

moderate. 

As discussed above, we expect the 

ECCHCP to provide substantial 

protection of the PCEs and protection of 

essential features for the Alameda 

whipsnake on ECCHCP conservation 

lands. We expect the ECCHCP to 

provide a greater level of management 

for the Alameda whipsnake on private 

lands than would designation of critical 

habitat on private lands. As a result, we 

do not anticipate any action on these 

lands would destroy or adversely 

modify the areas proposed as critical 

habitat. Therefore, we do not expect that 

including those areas in the final 

designation will lead to any changes to 

actions on the conservation lands to 

avoid destroying or adversely modifying 

that habitat. Therefore in this case, 

because of the ECCHCP protections, 

there is little to no additional protection 

from critical habitat, and thus the 

benefits of inclusion are small. 

A benefit of including an area in a 

critical habitat designation is the 

education of landowners and the public 

regarding the potential conservation 

value of the area. The inclusion of an 

area as critical habitat may focus and 

contribute to conservation efforts by 

other parties by clearly delineating areas 

of high conservation values for certain 

species. However, we believe that this 

conservation benefit has largely been 

achieved for the Alameda whipsnake 

through the hearings and workshops 

that have been held in the East Bay area 

associated with the listing of the species 

and previous critical habitat 

designation. In addition, the HCP itself 

undergoes public review and comment, 

providing another layer of educational 

benefit as the importance of this area for 

conservation of the species. Therefore 

the benefits of inclusion for educational 

purposes are extremely small. 

(2) Benefits of Exclusion 

The benefits of excluding lands 

within HCPs from critical habitat 

designation include relieving 

landowners, communities, and counties 

of any additional regulatory burden that 

might be imposed by a critical habitat 

designation. Many HCPs, particularly 

large regional HCPs such as the 

ECCHCP, take many years to develop 

and, upon completion, become regional 

conservation plans that are consistent 

with the recovery objectives for listed 

species that are covered within the plan 

area. In fact, designating critical habitat 

in areas covered by a pending HCP 

could result in the loss of species’

benefits if participants abandon the 

voluntary HCP process, in part because 

of the burden of the perceived 

additional regulatory compliance that 

such designation would entail. The time 

and cost of regulatory compliance for a 

critical habitat designation do not have 

to be quantified for them to be perceived 

as additional Federal regulatory burden 

sufficient to discourage continued 

voluntary participation in plans 

targeting listed species conservation. 

The conservation benefits of critical 

habitat are primarily regulatory or 

prohibitive in nature. Where consistent 

with the discretion provided by the Act, 

the Service believes it is necessary to 

implement policies that provide 

positive incentives to private 

landowners to voluntarily conserve 

natural resources and that remove or 

reduce disincentives to conservation 

(Wilcove et al. 1996). Thus, we believe 

it is essential for the recovery of the 

Alameda whipsnake to build on 

continued conservation activities such 

as the ECCHCP, and to provide positive 

incentives for other local government or 

private landowners who might be 

considering implementing voluntary 

conservation activities but have 

concerns about incurring incidental 

regulatory or economic impacts. 

Furthermore, an HCP or NCCP/HCP 

application must itself be consulted 

upon. Such a consultation would review 

the effects of all activities covered by 

the HCP that might adversely impact the 

species, including possibly significant 

habitat modification (see definition of 

‘‘harm’’ at 50 CFR 17.3), even without 

the critical habitat designation. In 

addition, Federal actions not covered by 

the HCP in areas occupied by listed 

species would still require consultation 

under section 7 of the Act and would be 

reviewed for possibly significant habitat 

modification in accordance with the 

definition of harm referenced above. 

This standard also would apply to all 

consultation conducted in the interim 

period prior to finalization of the 

ECCHCP, whether or not incidental take 

exemption is provided under section 7 

or section 10 of the Act. Therefore, we 

consider the benefits of exclusion to be 

moderate. 

(3) Benefits of Exclusion Outweigh the 

Benefits of Inclusion 

We have reviewed and evaluated the 

conservation measures identified for the 

Alameda whipsnake identified in the 

ECCHCP. Based on this evaluation, we 

currently find that the benefits of 

exclusion of the lands containing 

features essential to the conservation of 

the Alameda whipsnake in the planning 

area for the draft ECCHCP outweigh the 

benefits of including those portions of 

the draft ECCHCP area within Unit 4 as 

critical habitat. Our final determination 

will be made after we receive public 

comment on this proposed critical 

habitat designation. 

The exclusion of these lands from 

critical habitat would help preserve the 

partnerships that we have developed 

with the local jurisdiction and project 

proponent in the development of the 

ECCHCP. The educational benefits of 

critical habitat, including informing the 

public of areas that are essential for the 

long term conservation of the species, 

are still accomplished from material 

provided on our website and through 

public notice and comment procedures 

required to establish the ECCHCP. The 

public also has been informed through 

the public participation that occurs 

during the development of this regional 

HCP. For these reasons, we believe that 

designating critical habitat has little 

benefit in areas covered by the draft 

ECCHCP. 

(4) Exclusion Will Not Result in 

Extinction of the Species 

We believe that exclusion of these 

lands, which are considered occupied 

habitat, will not result in the extinction 

of the Alameda whipsnake. Actions that 

might adversely affect the subspecies 

are expected to have a Federal nexus, 

and would thus undergo a consultation 

with the Service under section 7 of the 

Act. The jeopardy standard of section 7 

of the Act, and routine implementation 

of habitat preservation through the 

section 7 process, as discussed in the 

economic analysis, provide assurance 

that the subspecies will not go extinct. 

In addition, the subspecies is protected 

from take prohibitions in section 9 of 

the Act. The exclusion leaves these 

protections unchanged from those that 

would exist if the excluded areas were 

designated as critical habitat. 

Critical habitat is being proposed for 

designation for the Alameda whipsnake 

in other areas that will be accorded the 

protection from adverse modification by 

Federal actions using the conservation 

standard based on the Ninth Circuit 

decision in Gifford Pinchot. 

Additionally, the species occurs on 

60622 Federal Register / Vol. 70, No. 200 / Tuesday, October 18, 2005 / Proposed Rules 

lands protected and managed either 

explicitly for the species, or indirectly 

through more general objectives to 

protect natural values; this factor acts in 

concert with the other protections 

provided under the Act for these lands 

absent designation of critical habitat on 

them, and acts in concert with 

protections afforded each species by the 

remaining critical habitat designation 

for the species, which leads us to find 

that exclusion of these lands will not 

result in extinction of the Alameda 

whipsnake. We do not believe that this 

exclusion would result in the extinction 

of the subspecies because the draft 

ECCHCP seeks to: (1) Preserve between 

12,254 to 13,983 ac (4,959 to 5,659 ha) 

of Alameda whipsnake habitat; (2) 

preserve major habitat connections 

linking existing public lands; (3) 

incorporate a range of habitat and 

population management and 

enhancement measures including 

monitoring, prescribed burning, and 

recreational use controls; (4) fully 

mitigate the impacts to covered species; 

(5) maintain ecosystem processes; and 

(6) contribute to the recovery of covered 

species. 

Relationship of Critical Habitat to the 

East Bay Regional Park—Exclusion 

Under Section 4(b)(2) 

The East Bay Regional Park District 

(EBRPD) manages 65 regional parks, 

recreation areas, wilderness, shorelines, 

preserves, and land bank areas covering 

over 95,000 ac (34,446 ha) in Alameda 

and Contra Costa counties. The EBRPD 

Board of Directors adopted the EBRPD 

Plan on December 17, 1996, under 

Resolution Number 1996–12–349. The 

EBRPD Plan provides for monitoring 

and conservation of rare, threatened, 

and endangered species, including the 

Alameda whipsnake. Species 

conservation efforts take precedence 

over other park activities if EBRPD 

activities are determined to have a 

significant adverse effect on rare, 

threatened, or endangered species 

(EBRPD 1997). 

We are proposing to exclude lands 

within the administrative boundaries for 

EBRPD from the designation of critical 

habitat for the Alameda whipsnake 

pursuant to section 4(b)(2) of the Act. A 

total of approximately 17,440 ac (7,057 

ha) is being considered for exclusion. 

(1) Benefits of Inclusion 

As stated previously, the benefits of 

designating critical habitat on lands 

within the boundaries of approved 

management plans are small. The 

EBRPD Plan provides for priority 

management and conservation of 

threatened and endangered species 

where park activities conflict with 

threatened and endangered species 

management. The EBRPD Plan provides 

a mechanism to accomplish these goals 

for the Alameda whipsnake through the 

implementation of specific conservation 

objectives outlined above. The principal 

benefit of designating critical habitat is 

that federally authorized or funded 

activities that may affect a species’

critical habitat would require 

consultation with us under section 7 of 

the Act. In the case of the EBRPD Plan, 

consultation must be initiated for any 

activity involving the Alameda 

whipsnake to evaluate the impact of the 

activity on the species for which the 

participants are seeking incidental take 

permits, pursuant to section 7 of the 

Act. The EBRPD currently holds a 

Service recovery permit, pursuant to 

section 10(a)(1)(A) of the Act. As with 

HCPs, the benefits of designating critical 

habitat on lands within the boundaries 

of areas properly managed for 

threatened and endangered species are 

small. 

(2) Benefits of Exclusion 

The benefits of excluding lands 

within approved management plans 

from critical habitat designation include 

relieving landowners, communities, and 

counties of any additional regulatory 

burden that might be imposed by 

critical habitat. Many conservation 

plans like the EBRPD Plan provide 

conservation benefits to unlisted 

sensitive species. Imposing an 

additional regulatory review as a result 

of the designation of critical habitat may 

undermine conservation efforts and 

partnerships in many areas. In fact, it 

could result in the loss of species’

benefits if participants abandon any 

voluntary HCP process in which they 

may be involved. The EBRPD is 

participating in the ECCHCP, and part of 

the strategy of the HCP is to link with 

lands such as those managed by the 

EBRPD for the conservation of the 

Alameda whipsnake. The loss of these 

connecting linkages as a part of the 

ECCHCP would reduce the conservation 

benefit for the Alameda whipsnake. 

Designation of critical habitat within the 

boundaries of management plans which 

provide conservation for a species could 

be viewed as a disincentive to those 

entities currently developing these 

plans or contemplating them in the 

future, because one of the incentives for 

undertaking conservation is greater ease 

of permitting where listed species are 

affected. Addition of a new regulatory 

requirement would remove a significant 

incentive for undertaking the time and 

expense of management planning. 

A related benefit of excluding lands 

within management plans from critical 

habitat designation is the unhindered, 

continued ability to seek new 

partnerships with future plan 

participants including States, counties, 

local jurisdictions, conservation 

organizations, and private landowners, 

which together can implement 

conservation actions that we would be 

unable to accomplish otherwise. If lands 

within approved management plan 

areas are designated as critical habitat, 

it would likely have a negative effect on 

our ability to establish new partnerships 

to develop these plans, particularly 

plans that address landscape-level 

conservation of species and habitats. By 

preemptively excluding these lands, we 

preserve our current partnerships and 

encourage additional conservation 

actions in the future. 

An applicant and any agency carrying 

out a Federally funded activity that may 

adversely affect Alameda whipsnake 

must enter into consultation with the 

Service under section 7 of the Act. 

While these consultations will not look 

specifically at the issue of adverse 

modification to critical habitat, unless 

critical habitat has already been 

designated within the proposed plan 

area, it will determine if the actions 

jeopardize the species in the plan area. 

The jeopardy analysis is similar to the 

analysis of adverse modification to 

critical habitat. Additionally, Federal 

actions not covered by an HCP or 

approved management plan in areas 

occupied by listed species would still 

require consultation under section 7 of 

the Act. Plans such as the EBRPD Plan 

typically provide greater conservation 

benefits to the covered species than 

section 7 consultations because they: (1) 

Assure the long-term protection and 

management of a covered species and its 

habitat; (2) include the development of 

biological information to guide 

conservation efforts and assist in species 

conservation; and (3) create innovative 

solutions to conserve species while still 

allowing public use of the area. 

Maps delineating essential habitat for 

the Alameda whipsnake, overlaid with 

the boundary area for the EBRPD, are 

available for public review and 

comment at the Sacramento Fish and 

Wildlife Office (see ADDRESSES). These 

maps are provided to allow the public 

the opportunity to adequately comment 

on these potential exclusions. 

(3) Benefits of Exclusion Outweigh the 

Benefits of Inclusion 

We have reviewed and evaluated the 

conservation measures identified for the 

Alameda whipsnake identified in the 

EBRPD. Based on this evaluation, we 

Federal Register / Vol. 70, No. 200 / Tuesday, October 18, 2005 / Proposed Rules 60623 

currently find that the benefits of 

exclusion of the lands essential to the 

conservation of the Alameda whipsnake 

within the boundaries of the EBRPD 

land outweigh the benefits of including 

those portions of land as critical habitat. 

Our final determination will be made 

after we receive public comment on this 

proposed critical habitat designation. 

The exclusion of these lands from 

critical habitat would help preserve the 

partnerships that we have developed 

with the local jurisdiction. The 

educational benefits of critical habitat, 

including informing the public of areas 

that are essential for the long term 

conservation of the species, are still 

accomplished from material provided 

on our website and through public 

notice and required comment 

procedures. The public also has been 

informed through the public 

participation that occurs during the 

development of this proposed 

designation and previous listing and 

critical habitat actions for the 

subspecies. For these reasons, we 

believe that designating critical habitat 

has little benefit in areas managed by 

the EBRPD. 

(4) Exclusion Will Not Result in 

Extinction of the Species 

We believe that exclusion of these 

lands, which are considered occupied 

habitat, would not result in the 

extinction of the Alameda whipsnake. 

Actions which might adversely affect 

the subspecies are expected to have a 

Federal nexus, and would thus undergo 

a consultation with the Service under 

section 7 of the Act. The jeopardy 

standard of section 7 of the Act, and 

routine implementation of habitat 

preservation through the section 7 

process, provide assurance that the 

subspecies will not go extinct. In 

addition, the subspecies is protected 

from the take prohibitions under section 

9 of the Act. The exclusion leaves these 

protections unchanged from those that 

would exist if the excluded areas were 

designated as critical habitat. 

Critical habitat is being proposed for 

designation for the Alameda whipsnake 

in other areas that will be accorded the 

protection from adverse modification by 

Federal actions using the conservation 

standard based on the Ninth Circuit 

decision in Gifford Pinchot. 

Additionally, the subspecies occurs on 

lands protected and managed either 

explicitly for the subspecies, or 

indirectly through more general 

objectives to protect natural values; this 

factor acts in concert with the other 

protections provided under the Act for 

these lands absent designation of critical 

habitat on them, and acts in concert 

with protections afforded the subspecies 

by the remaining critical habitat 

designation for the subspecies, which 

leads us to find that exclusion of these 

lands will not result in extinction of the 

Alameda whipsnake. We do not believe 

that this exclusion would result in the 

extinction of the subspecies because the 

subspecies is found in other areas and 

the EBRPD Plan provides for monitoring 

and conservation of rare, threatened, 

and endangered species, including the 

Alameda whipsnake. Species 

conservation efforts take precedence 

over other park activities if EBRPD 

activities are determined to have a 

significant adverse effect on rare, 

threatened, or endangered species 

(EBRPD 1997). 

Relationship of Critical Habitat to the 

State Park Lands—Exclusion Under 

Section 4(b)(2) 

Mount Diablo State Park 

Approximately 97 percent of the 

lands within the boundary of Mount 

Diablo State Park are currently being 

proposed as critical habitat. The total 

amount of State-owned lands proposed 

for critical habitat within Mount Diablo 

State Park is approximately 13,874 ac 

(5,615 ha). Currently, we know of no 

specific management plan or 

conservation activities for the Alameda 

whipsnake within Mount Diablo State 

Park. However, the lands within the 

park are publicly owned, and the 

natural resources within the park are 

managed in a way to preserve the 

ecological diversity of the area. The 

designation of critical habitat would not 

have any appreciable effect on the 

development or implementation of 

public education programs because 

these lands already are publicly owned, 

and critical habitat designation provides 

little gain in the way of increased 

recognition for special habitat values on 

lands publicly protected and managed 

lands. Exclusion of these lands would 

not increase the likelihood that 

management activities would be 

proposed that would appreciably 

diminish the value of the habitat for 

conservation of the Alameda 

whipsnake. 

We are, however, not currently 

proposing to exclude from the 

designation the State Park lands at 

Mount Diablo State Park. Should 

information become available during the 

public comment period on this 

proposed rule that would support an 

exclusion of these State lands, we will 

conduct an analysis of such information 

and make our determination of the 

appropriateness of such an exclusion in 

our final designation. 

Relationship of Critical Habitat to 

Department of Energy Lands—Exclusion 

Under Section 4(b)(2) 

Approximately 2,492 ac (1,009 ha) of 

proposed critical habitat for the 

Alameda whipsnake within Unit 5A are 

owned by the Department of Energy. 

The lands are located in eastern 

Alameda and western San Joaquin 

counties. The Department of Energy has 

used these lands within the past as a 

testing facility. Currently, we know of 

no specific management plan or 

conservation activities for the Alameda 

whipsnake on these lands. However, the 

lands are publicly owned and currently 

protected from development. Any 

activities that may take place which 

may affect the Alameda whipsnake or 

its habitat would be subject to 

consultation under section 7 of the Act. 

We are, however, not currently 

proposing to exclude from critical 

habitat designation the Department of 

Energy lands in eastern Alameda and 

western San Joaquin counties. Should 

information become available during the 

public comment period on the proposed 

rule that would support an exclusion of 

the Department of Energy lands, we will 

conduct an analysis of such information 

and make our determination of the 

appropriateness of such an exclusion in 

our final designation. 

Economic Analysis 

An analysis of the economic impacts 

of proposing critical habitat for the 

Alameda whipsnake 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 on the 

analysis. At that time, copies of the draft 

economic analysis will be available for 

downloading from the Internet at 

http://www.fws.gov/pacific/sacramento, 

or by contacting the Sacramento Fish 

and Wildlife Office directly (see 

ADDRESSES). 

After reviewing the economic 

analysis, the public comment on it, and 

the public comment on this proposal, 

we may exclude additional areas under 

section 4(b)(2) based on economic or 

other relevant impact. Our regulations 

expressly contemplate that these 

decisions would occur after the 

comment period (50 CFR 424.19), and 

do not require advance public notice of 

intent to make specific exclusions. 

While we are seeking public comment 

on those possible exclusions of which 

we are now aware, we also want to 

insure that the public is aware that the 

economic analysis and all public 

comments may lead us to exclude other 

areas. 

60624 Federal Register / Vol. 70, No. 200 / Tuesday, October 18, 2005 / Proposed Rules 

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 a copy 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 public 

comment periods 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 (see DATES). 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 (groupings 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? 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:

Required Determinations 

Regulatory Planning and Review 

In accordance with Executive Order 

12866, this document is a significant 

rule in that it may raise novel legal and 

policy issues, but it is not anticipated to 

have an annual effect on the economy 

of $100 million or more or affect the 

economy in a material way. Due to the 

tight timeline for publication in the 

Federal Register, the Office of 

Management and Budget (OMB) has not 

formally reviewed this rule. 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. This economic analysis 

also will be used to determine 

compliance with Executive Order 

12866, Regulatory Flexibility Act, Small 

Business Regulatory Enforcement 

Fairness Act, and Executive Order 

12630. 

Further, Executive Order 12866 

directs Federal Agencies promulgating 

regulations to evaluate regulatory 

alternatives (Office of Management and 

Budget, Circular A–4, September 17, 

2003). Pursuant to Circular A–4, once it 

has been determined that the Federal 

regulatory action is appropriate, then 

the agency will need to consider 

alternative regulatory approaches. Since 

the determination of critical habitat is a 

statutory requirement pursuant to the 

Endangered Species Act of 1973, as 

amended (Act) (16 U.S.C. 1531 et seq.), 

we must then evaluate alternative 

regulatory approaches, where feasible, 

when promulgating a designation of 

critical habitat. 

In developing our designations of 

critical habitat, we consider economic 

impacts, impacts to national security, 

and other relevant impacts pursuant to 

section 4(b)(2) of the Act. Based on the 

discretion allowable under this 

provision, we may exclude any 

particular area from the designation of 

critical habitat providing that the 

benefits of such exclusion outweigh the 

benefits of specifying the area as critical 

habitat and that such exclusion would 

not result in the extinction of the 

species. As such, we believe that the 

evaluation of the inclusion or exclusion 

of particular areas, or a combination 

thereof, in a designation constitutes our 

regulatory alternative analysis. 

Within these areas, the types of 

Federal actions or authorized activities 

that we have identified as potential 

concerns are listed above in the section 

on Section 7 Consultation. The 

availability of the draft economic 

analysis will be announced in the 

Federal Register and in local 

newspapers so that it is available for 

public review and comment. When 

completed, the draft economic analysis 

can be obtained from the Internet 

website at http://www.fws.gov/pacific/ 

sacramento/ or by contacting the 

Sacramento Fish and Wildlife Office 

directly (see ADDRESSES). 

Regulatory Flexibility Act (5 U.S.C. 601 

et seq.) 

Our assessment of economic effect 

will be completed prior to any final 

rulemaking based upon review of the 

draft economic analysis prepared 

pursuant to section 4(b)(2) of the Act 

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). 

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 Act 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. The Service will include 

with the notice of availability, as 

appropriate, an initial regulatory 

flexibility analysis or a certification that 

Federal Register / Vol. 70, No. 200 / Tuesday, October 18, 2005 / Proposed Rules 60625 

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. 

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 Alameda whipsnake 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, 

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 of the Act. While 

non-Federal entities that receive Federal 

funding, assistance, or permits, or that 

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) Due to current public knowledge 

of the subspecies’ protection, and the 

prohibition against take of the 

subspecies both within and outside of 

the designated areas, we do not 

anticipate that this rule will 

significantly or uniquely affect small 

governments. As such, 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. 

Federalism 

In accordance with Executive Order 

13132, the rule does not have significant 

Federalism effects. A Federalism 

assessment is not required. In keeping 

with Department of Interior 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 may have 

some benefit to these governments in 

that the areas essential to the 

conservation of the subspecies are more 

clearly defined, and the PCEs of the 

habitat necessary to the survival of the 

subspecies 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 

consultations under section 7 of the Act 

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 

Act. This proposed rule uses standard 

property descriptions and identifies the 

PCEs within the designated areas to 

assist the public in understanding the 

habitat needs of the Alameda 

whipsnake. 

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 

It is our position that, outside the 

Tenth Circuit, we do not need to 

prepare environmental analyses as 

defined by the NEPA in connection with 

designating critical habitat under the 

Act. We published a notice outlining 

our reasons for this determination in the 

Federal Register on October 25, 1983 

(48 FR 49244). This assertion was 

upheld in the courts of the Ninth Circuit 

(Douglas County v. Babbitt, 48 F.3d 

1495 (9th Cir. Ore. 1995), cert. denied 

116 S. Ct. 698 (1996)). 

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 

60626 Federal Register / Vol. 70, No. 200 / Tuesday, October 18, 2005 / Proposed Rules 

Governments’’ (59 FR 22951), Executive 

Order 13175, and the Department of 

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 Alameda whipsnake. Therefore, 

critical habitat for the Alameda 

whipsnake is not being proposed on 

Tribal lands.

Proposed Regulation Promulgation 

Accordingly, we propose to amend 

part 17, subchapter B of chapter I, title 

50 of the Code of Federal Regulations, 

as set forth below: 

PART 17—[AMENDED] 

1. The authority citation for part 17 

continues to read as follows: 

Authority: 16 U.S.C. 1361–1407; 16 U.S.C. 

1531–1544; 16 U.S.C. 4201–4245; Pub. L. 99–

625, 100 Stat. 3500; unless otherwise noted. 

2. In § 17.95(c), revise the entry for 

‘‘Alameda Whipsnake (Masticophis 

lateralis euryxanthus’’ to read as 

follows: 

§ 17.95 Critical habitat—fish and wildlife. 

* * * * * 

(c) Reptiles. 

* * * * * 

Alameda Whipsnake (Masticophis 

lateralis euryxanthus) 

(1) Critical habitat units are depicted 

for Alameda, Contra Costa, San Joaquin, 

and Santa Clara counties, California, on 

the maps below. 

(2) The primary constituent elements 

(PCEs) of critical habitat for the 

Alameda whipsnake (Masticophis 

lateralis euryxanthus) are: 

(i) Scrub communities with a mosaic 

of open and closed canopy: Scrub/shrub 

vegetation dominated by low to 

medium-stature woody shrubs with a 

mosaic of open and closed canopy as 

characterized by the chamise, chamiseeastwood manzanita, chaparral 

whitethorn, and interior live oak shrub 

vegetation series as identified in the 

Manual of California Vegetation (Sawyer 

and Keeler-Wolf 1995), A Guide to 

Wildlife Habitats of California (Mayer 

and Laudenslayer 1988), and California 

Wildlife Habitat Relationship System 

(CDFG 1998). These vegetation series 

occur within the range of the Alameda 

whipsnake from near sea level to 

approximately 3,850 ft (1,170 m). Such 

scrub/shrub vegetation within these 

series form a pattern of open and closed 

canopy which is used by the Alameda 

whipsnake to provide shelter from 

predators, temperature regulation by 

providing sunny and shady locations, 

prey-viewing opportunities, and nesting 

habitat and substrate. These features 

contribute to support a prey base 

consisting of western fence lizards and 

other prey species such as skinks, frogs, 

snakes, and birds. These areas are the 

core areas where Alameda whipsnakes 

reside most frequently and are used for 

retreats (shelter), thermoregulation, 

foraging, and provide additional prey 

population support functions. 

(ii) Other lands adjacent to the 

Alameda whipsnake’s home range as 

described in PCE 1, i.e., scrub 

communities with a mosaic of open and 

closed canopy of varying vegetation 

types: Other lands adjacent to PCE 1 

composed of either one or both 

woodland or annual grassland 

vegetation series such as blue oak, coast 

live oak (Quercus sp.), California bay 

(Umbellularia californica), California 

buckeye, and California annual 

grassland vegetation series (as identified 

in the Manual of California Vegetation 

(Sawyer and Keeler-Wolf 1995), A 

Guide to Wildlife Habitats of California 

(Mayer and Laudenslayer 1988), and 

California Wildlife Habitat Relationship 

System (CDFG 1998)) are PCE 2. These 

vegetation series establish a pattern of 

vegetation which provide opportunities 

for: 

(A) Foraging by allowing snakes to 

come in contact with and visualize, 

track, and capture prey (especially 

western fence lizards along with other 

prey such as skinks, frogs, birds); 

(B) Short and long distance dispersal 

within, between, or to adjacent to areas 

containing essential features (i.e., PCE 1 

or PCE 3); and 

(C) Contact with other Alameda 

whipsnakes for mating and 

reproduction. 

(iii) Rock outcrops, talus, and small 

mammal burrows within the essential 

core scrub or adjacent areas containing 

essential features identified in PCE 1 

and 2: Rock outcrops, talus, and small 

mammal burrows within either rock 

outcrops or grassland or other 

vegetation series identified in PCE 2 

located in close proximity to or 

embedded within those essential core 

scrub/shrub areas (PCE 1) and 

intervening non-scrub communities 

(PCE 2) that support a prey base, are 

PCE 3. These areas are used for retreats 

(shelter), hibernacula, foraging, 

dispersal, mating, and provide 

additional prey population support 

functions. 

(3) Critical habitat does not include 

manmade structures existing on the 

effective date of this rule such as 

buildings, aqueducts, airports, and 

roads, and the land on which such 

structures are located. 

(4) GIS 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.
