50 CFR Part 17 

RIN 1018–AU86 

Endangered and Threatened Wildlife 

and Plants; Designation of Critical 

Habitat for Acanthomintha ilicifolia 

(San Diego thornmint) 

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 

Acanthomintha ilicifolia (San Diego 

thornmint) under the Endangered 

Species Act of 1973, as amended (Act). 

We have determined that a total of 

approximately 1,936 acres (ac) (783 

hectares (ha)) in San Diego County, 

California, meets the definition of 

critical habitat. We are proposing to 

exclude 1,302 ac (527 ha) from the 

critical habitat designation. If these 

proposed exclusions are adopted, this 

would result in a designation of critical 

habitat of approximately 634 ac (257 ha) 

of land under Federal (553 ac (224 ha)), 

and State and local (81 ac (33 ha)), 

ownership in San Diego County, 

California. 

DATES: We will accept comments from 

all interested parties until May 14, 2007. 

We must receive requests for public 

hearings, in writing, at the address 

shown in the ADDRESSES section by 

April 30, 2007. 

ADDRESSES: If you wish to comment on 

the proposed rule, you may submit your 

comments and materials identified by 

RIN 1018–AU86, by any of the following 

methods:

SUPPLEMENTARY INFORMATION:

Public Comments Solicited 

We intend that any final action 

resulting from this proposal will be as 

accurate and as effective as possible. 

Therefore, comments or suggestions 

from the public, other concerned 

governmental agencies, the scientific 

community, industry, or any other 

interested party concerning this 

proposed rule are hereby solicited. 

Comments particularly are sought 

concerning: 

(1) The reasons any habitat should or 

should not be determined to be critical 

habitat as provided by section 4 of the 

Act, including whether the benefit of 

designation will outweigh any threats to 

the species due to designation; 

(2) Specific information on the 

amount and distribution of 

Acanthomintha ilicifolia habitat and 

what areas should be included in the 

designation that were occupied at the 

time of listing that contain the features 

essential for the conservation of the 

species, and why and what areas that 

were not occupied at the time of listing 

are essential to the conservation of the 

species; 

(3) Land use designations and current 

or planned activities in the subject areas 

and their possible impacts on proposed 

critical habitat; 

(4) Our proposed exclusion of 1,302 

acres (ac) (527 hectares (ha)) of nonFederal lands already conserved or 

targeted for conservation within subarea 

plans under the San Diego Multiple 

Species Conservation Program (MSCP) 

and the San Diego Multiple Habitat 

Conservation Program (MHCP) from the 

final designation of critical habitat for 

Acanthomintha ilicifolia under section 

4(b)(2) of the Act. We are specifically 

seeking public comment on our 

proposed exclusion of lands covered 

under the City of Encinitas subarea plan 

of the MHCP (see Exclusions Under 

Section 4(b)(2) of the Act for details of 

these HCPs). It is our understanding that 

little progress has been made by the City 

of Encinitas to finalize their subarea 

plan since the 2001 release of the draft 

plan. Based on information received 

during the public comment period, the 

Secretary may determine that sufficient 

progress has not been made and that 

lands within the City of Encinitas’ 

subarea plan should not be excluded 

from the final designation. Specifically, 

useful information would include: 

Whether essential lands within 

Encinitas are being managed, or are 

proposed to be managed, to conserve A. 

ilicifolia, and; the outlook for 

completion of the draft subarea plan. 

Please provide information concerning 

whether the benefits of exclusion of any 

of these specific areas outweigh the 

benefits of their inclusion in designated 

critical habitat. If the Secretary 

determines the benefits of including 

these lands outweigh the benefits of 

excluding them, they will not be 

excluded from final critical habitat; 

(5) Any foreseeable economic, 

national security, or other potential 

impacts resulting from the proposed 

designation and, in particular, any 

impacts on small entities; and 

(6) Whether our approach to 

designating critical habitat could be 

improved or modified in any way to 

provide for greater public participation 

and understanding, or to assist us in 

accommodating public concerns and 

comments. 

If you wish to comment, you may 

submit your comments and materials 

concerning this proposal by any one of 

several methods (see ADDRESSES). Please 

submit e-mail comments to 

fw8cfwocomments@fws.gov. Please also 

include ‘‘Attn: RIN 1018–AU86’’ in your 

e-mail subject line and your name and 

return address in the body of your 

message. If you do not receive a 

confirmation from the system that we 

have received your message, contact us 

directly by calling our Carlsbad Fish 

and Wildlife Office at phone number 

760–431–9440. Please note that 

comments must be received by the date 

specified in DATES in order to be 

considered. 

Our practice is to make comments, 

including names and home addresses of 

respondents, available for public review 

during regular business hours. 

Individual respondents may request that 

we withhold their names and home 

addresses, etc., but if you wish us to 

consider withholding this information, 

you must state this prominently at the 

beginning of your comments. In 

addition, you must present rationale for 

withholding this information. This 

rationale must demonstrate that 

disclosure would constitute a clearly 

unwarranted invasion of privacy. 

Unsupported assertions will not meet 

this burden. In the absence of 

exceptional, documentable 

circumstances, this information will be 


cprice-sewell on PROD1PC66 with PROPOSALS2
Federal Register / Vol. 72, No. 49 / Wednesday, March 14, 2007 / Proposed Rules 11947 

released. We will always make 

submissions from organizations or 

businesses, and from individuals 

identifying themselves as 

representatives of or officials of 

organizations or businesses, available 

for public inspection in their entirety. 

Role of Critical Habitat in Actual 

Practice of Administering and 

Implementing the Act 

Attention to and protection of habitat 

is paramount to successful conservation 

actions. The role that designation of 

critical habitat plays in protecting 

habitat of listed species, however, is 

often misunderstood. As discussed in 

more detail below in the discussion of 

exclusions under section 4(b)(2) of the 

Act, there are significant limitations on 

the regulatory effect of designation 

under section 7(a)(2) of the Act. In brief, 

(1) designation provides additional 

protection to habitat only where there is 

a Federal nexus; (2) the protection is 

relevant only when, in the absence of 

designation, destruction or adverse 

modification of the critical habitat 

would in fact take place (in other words, 

other statutory or regulatory protections, 

policies, or other factors relevant to 

agency decision-making would not 

prevent the destruction or adverse 

modification); and (3) designation of 

critical habitat triggers the prohibition 

of destruction or adverse modification 

of that habitat, but it does not require 

specific actions to restore or improve 

habitat. 

Currently, only 483 species, or 37 

percent of the 1,311 listed species in the 

United States under the jurisdiction of 

the Service have designated critical 

habitat. We address the habitat needs of 

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, the 

section 10 incidental take permit 

process and cooperative, nonregulatory 

efforts with private landowners. The 

Service believes that it is these measures 

that may make the difference between 

extinction and survival for many 

species. 

In considering exclusions of areas 

proposed for designation, we evaluate 

the benefits of designation in light of 

Gifford Pinchot Task Force v. U.S. Fish 

and Wildlife Service, 378 F.3d 1059 (9th 

Cir. 2004) (hereinafter Gifford Pinchot). 

In that case, the Ninth Circuit 

invalidated the Service’s regulation 

defining ‘‘destruction or adverse 

modification of critical habitat.’’ In 

response, on December 9, 2004, the 

Director issued guidance to be 

considered in making section 7 adverse 

modification determinations. This 

proposed critical habitat designation 

does not use the invalidated regulation 

in our consideration of the benefits of 

including areas in the proposed 

designation. The Service will carefully 

manage future consultations that 

analyze impacts to designated critical 

habitat, particularly those that appear to 

be resulting in an adverse modification 

determination. Such consultations will 

be reviewed by the Regional Office prior 

to finalizing to ensure that an adequate 

analysis has been conducted that is 

informed by the Director’s guidance. 

On the other hand, to the extent that 

designation of critical habitat provides 

protection, that protection can come at 

significant social and economic cost. In 

addition, the mere administrative 

process of designation of critical habitat 

is expensive, time-consuming, and 

controversial. The current statutory 

framework of critical habitat, combined 

with past judicial interpretations of the 

statute, make critical habitat the subject 

of excessive litigation. As a result, 

critical habitat designations are driven 

by litigation and courts rather than 

biology, and made at a time and under 

a timeframe that limits our ability to 

obtain and evaluate the scientific and 

other information required to make the 

designation most meaningful. 

In light of these circumstances, 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. 

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 courtordered designations have left the 

Service with limited ability to provide 

for public participation or to ensure a 

defect-free rulemaking process before 

making decisions on listing and critical 

habitat proposals, due to the risks 

associated with noncompliance with 

judicially imposed deadlines. This in 

turn fosters a second round of litigation 

in which those who fear adverse 

impacts from critical habitat 

designations challenge those 

designations. The cycle of litigation 

appears endless, and is very expensive, 

thus diverting resources from 

conservation actions that may provide 

relatively more benefit to imperiled 

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 et seq.). These costs, which 

are not required for many other 

conservation actions, directly reduce the 

funds available for direct and tangible 

conservation actions. 

Background 

It is our intent to discuss only those 

topics directly relevant to the 

designation of critical habitat in this 

proposed rule. For more information on 

the biology and ecology of 

Acanthomintha ilicifolia, please refer to 

the final rule listing the species as 

threatened published in the Federal 

Register on October 13, 1998 (63 FR 

54938). This species has been listed by 

the State of California as endangered 

since 1982. 

Species Description and Life History 

Acanthomintha ilicifolia (San Diego 

thornmint) is an annual member of the 

mint family in the genus 

Acanthomintha. This plant ranges in 

height from 2 to 6 inches (in) (5 to 15 

centimeters (cm)) and has white, twolipped, tubular flowers with rosecolored markings on the lower lip 

(Jokerst 1993, p. 713). Members of this 

genus have paired leaves and several 

sharp spiny bracts (modified leaves) 

below whorled flowers. Acanthomintha 

ilicifolia can be distinguished from 

other members of the genus by its 

flower, which has hairless anthers and 

style.

11948 Federal Register / Vol. 72, No. 49 / Wednesday, March 14, 2007 / Proposed Rules 

Distribution, Ecology, and Habitat 

Acanthomintha ilicifolia usually 

occurs on heavy clay soils in open areas 

surrounded by shrubby vegetation. 

These openings are generally found 

within coastal sage scrub, chaparral and 

native grassland of coastal San Diego 

County and south to San Telmo in 

northern Baja California, Mexico 

(Beauchamp 1986, p. 175; Reiser 2001, 

pp. 3–5). Acanthomintha ilicifolia is 

frequently associated with gabbro soils, 

which are derived from igneous rock, 

and gray calcareous clays derived from 

soft calcareous sandstone (Oberbauer 

and Vanderwier 1991, pp. 208–209). 

This species is endemic to San Diego 

County, California, and northwestern 

Baja California, Mexico, and grows on 

open clay lenses described as friable, 

meaning that these soils have a loose, 

crumbly texture. 

In the final listing rule for 

Acanthomintha ilicifolia (63 FR 54938, 

October 13, 1998), 32 of 52 historic 

populations were presumed to be extant 

(still in existence). In the listing rule we 

estimated that the total number of 

individual plants in all remaining 

populations was approximately 150,000 

to 170,000 (63 FR 54938). Throughout 

this proposed rule, occurrences of A. 

ilicifolia are referred to by their element 

occurrence (EO) number. This is a code 

that is assigned to each specific location 

of rare species that is cataloged in the 

California Natural Diversity Database 

(CNDDB). Element occurrences do not 

necessarily represent populations, but 

are used to represent areas where a 

species is found. Element occurrences 

that are close together may be part of the 

same population. Therefore, the number 

of element occurrences does not 

represent the number of populations 

that exist for this species. For the 

purpose of this proposed critical habitat 

designation, we are assuming that 

element occurrences within one mile 

(1.6 kilometers (km)) of each other and 

on habitat that is not fragmented by 

roads or structures are part of the same 

population. 

Through surveys associated with the 

development of Habitat Conservation 

Plans (HCPs) and additional surveys on 

public and private lands since the time 

of listing, additional populations of A. 

ilicifolia have been discovered. We 

currently have data for a total of 88 

element occurrences (or 64 populations) 

of which 54 element occurrences (or 34 

populations) are extant or presumed 

extant and 34 element occurrences (or 

30 populations) are considered to be 

extirpated (no longer in existence) or 

possibly extirpated. Specifically, we 

consider 68 element occurrences to have 

been known at the time of listing in 

1998 (52 historic populations) and an 

additional 20 element occurrences to 

have been discovered since the time of 

listing (12 new populations). Detailed 

information about the new element 

occurrences is available upon request 

from the Carlsbad Fish and Wildlife 

Office (see ADDRESSES). 

Previous Federal Actions 

Acanthomintha ilicifolia was 

federally listed as threatened on October 

13, 1998 (63 FR 54938), and has been 

listed as endangered by the State of 

California since 1982 (CDFG 2006, p.1). 

This species currently does not have a 

recovery plan. 

At the time this plant was federally 

listed, the Service compared the benefits 

of designating critical habitat to the 

detrimental effects (threats) of increased 

collection and vandalism and the 

potential for private landowner 

misunderstandings about the effects of 

critical habitat designation on private 

lands (63 FR 54938, pp. 54951–54953). 

Additionally, we conflated the jeopardy 

standard with the standard for 

destruction or adverse modification of 

critical habitat, stating that a jeopardy 

finding would be equivalent to a finding 

of adverse modification of critical 

habitat thereby resulting in identical 

section 7 findings. Based on these 

factors, the Service found that 

designation of critical habitat for A. 

ilicifolia was not prudent. 

On August 10, 2004, the Center for 

Biological Diversity and California 

Native Plant Society challenged our 

failure to designate critical habitat for 

this species as well as four other plant 

species (Center for Biological Diversity 

v. Norton, C–04–3240 JL (N. D. Cal.)). In 

settlement of the lawsuit, the Service 

agreed to withdraw our previous not 

prudent finding and deliver a proposed 

determination of critical habitat, if 

prudent, to the Federal Register on or 

before February 28, 2007 and a final 

designation by February 28, 2008. 

We have re-evaluated the prudency of 

designating critical habitat for this 

species. Despite the potential threats to 

this species from collection and 

vandalism and the continuing potential 

for private landowner 

misunderstandings about the effects of 

critical habitat designation on private 

land, we believe that designation of 

critical habitat will benefit A. ilicifolia. 

As a result of the Gifford Pinchot court 

ruling in 2004, we now recognize the 

jeopardy standard and the standard for 

destruction or adverse modification of 

critical habitat are separate and distinct. 

Additionally, we recognize critical 

habitat designations may provide 

benefits to the recovery of a species. 

Therefore, we now find designation of 

critical habitat for A. ilicifolia to be 

prudent because designation of critical 

habitat has the potential to provide 

greater protections to the species and its 

habitat than the jeopardy standard 

under section 7(a)(2) of the Act. 

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, as defined under 

section 3 of the Act, means to use and 

the use of all methods and procedures 

which are necessary to bring any 

endangered species or threatened 

species to the point at which the 

measures provided pursuant to the Act 

are no longer necessary. Such methods 

and procedures include, but are not 

limited to, all activities associated with 

scientific resources management such as 

research, census, law enforcement, 

habitat acquisition and maintenance, 

propagation, live trapping, and 

transplantation, and, in the 

extraordinary case where population 

pressures within a given ecosystem 

cannot be otherwise relieved, may 

include regulated taking. 

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 of the Act 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. 

Section 7 of the Act is a purely 

protective measure and does not require 

implementation of restoration, recovery, 

or enhancement measures. 

To be included in a critical habitat 

designation, the habitat within the area 

occupied by the species must first have 

features that are essential to the 

conservation of the species. Critical 

habitat designations identify, to the 


cprice-sewell on PROD1PC66 with PROPOSALS2
Federal Register / Vol. 72, No. 49 / Wednesday, March 14, 2007 / Proposed Rules 11949 

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, as 

defined at 50 CFR 424.12(b)). Habitat 

within the geographic area occupied by 

the species at the time of listing may be 

included in critical habitat only if the 

essential features thereon may require 

special management considerations or 

protection. Areas outside of the 

geographic area occupied by the species 

at the time of listing may only be 

included in critical habitat if they are 

essential for the conservation of the 

species. Accordingly, when the best 

available scientific data do not 

demonstrate that the conservation needs 

of the species require additional areas, 

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 not known to be 

occupied at the time of listing will 

likely, but not always, be essential to the 

conservation of the species and, 

therefore, typically included in the 

critical habitat designation. 

The Service’s Policy on Information 

Standards Under the Endangered 

Species 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 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)(2) of the 

Act, we used the best scientific data 

available in determining areas that 

contain the features that are essential to 

the conservation of Acanthomintha 

ilicifolia. This includes information 

from the proposed listing rule (60 FR 

40549, August 9, 1995); final listing rule 

(63 FR 54938, October 13, 1998); data 

from research and survey observations 

published in peer-reviewed articles; site 

visits and unpublished survey data; 

regional Geographic Information System 

(GIS) layers including soil, vegetation 

and species coverages from San Diego 

County and data compiled in the 

California Natural Diversity Database 

(CNDDB). More specifically, the 

information sources used for this 

proposal include: (1) CNDDB element 

occurrence data (2005 and 2006); (2) 

Bauder and McMillan (1994, pp. 1–87); 

(3) McMillan (2001, pp. 1–91); (4) 

herbarium records from San Diego 

Natural History Museum, University of 

California at Berkeley and Rancho Santa 

Ana Botanical Garden; (5) personal 

communications with A. ilicifolia 

experts (Bauder 2006; Hanson 2006; 

Kelly 2005; McMillan 2006; Sproul 

2006; and Vinje 2006); (6) site visits by 

Service biologists to several known 

element occurrences of A. ilicifolia in 

2005 and 2006; and (7) information 

provided by the Cleveland National 

Forest of the U.S. Forest Service (Winter 

and Young 2005). 

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 consider 

those areas occupied by the species at 

the time of listing that contain physical 

or biological features (primary 

constituent elements (PCEs)) that are 

essential to the conservation of the 

species, and that may require special 

management considerations or 

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 of offspring, germination, 

and seed dispersal; and habitats that are 

protected from disturbance or are 

representative of the historic 

geographical and ecological 

distributions of a species. 

The specific primary constituent 

element required for Acanthomintha 

ilicifolia is derived from the biological 

needs of A. ilicifolia as described in the 

proposed and final listing rules (60 FR 

40549; 63 FR 54938). 

Space for Individual and Population 

Growth and Normal Behavior 

Acanthomintha ilicifolia occurs on 

isolated patches of clay soils derived 

from gabbro and soft calcareous 

sandstone substrates (Oberbauer and 

Vanderwier 1991, pp. 208–209) (PCE). 

The soils derived from gabbro substrates 

are red to dark brown clay soils, and 

those derived from soft calcareous 

sandstone are gray, sometimes loamy, 

clay soils. These patches of clay soils 

are called ‘‘clay lenses,’’ and in San 

Diego County and northern Baja 

California, Mexico, clay lenses are 

known to support a variety of narrow 

endemic (restricted to a specific 

geographic area) plants. Clay lenses tend 

to have an open or unpopulated look 

because many common species cannot 

tolerate living on these clay soils. Clay 

lenses are typically devoid of woody, 

perennial shrubs (PCE). It is believed 

shrubs have difficulty surviving on 

these soils because in the rainy winter 

months these soils become saturated 


cprice-sewell on PROD1PC66 with PROPOSALS2
11950 Federal Register / Vol. 72, No. 49 / Wednesday, March 14, 2007 / Proposed Rules 

with water and the large root systems of 

shrubs are not able to get oxygen 

(Oberbauer and Vanderwier 1991, pp. 

208–209). Also, as the soils become 

saturated they expand and move, and 

when the soils dry they contract and 

crack, making it difficult for shrubs to 

become established. Likewise, relatively 

few common annual plant species 

inhabit clay lenses due to the harsh 

conditions, and those plants that are 

adapted to these conditions, in some 

cases, have become differentiated from 

their common relatives. Due to the 

absence of most common native 

vegetation from these clay lenses, the 

areas where A. ilicifolia occurs appear 

as open areas in a matrix of coastal sage 

scrub or chaparral (PCE). 

Clay lenses are generally inhabited by 

a specific flora that consist of forbs, 

native grasses, and geophytes (perennial 

plants propagated by buds on 

underground bulbs, tubers, or corms 

such as lilies, iris, and onions). Native 

plant species that characterize the 

vegetation found with Acanthomintha 

ilicifolia on clay lenses include 

Hesperevax sparsiflora var. sparsiflora 

(erect evax), Harpagonella palmeri 

(Palmer’s grappling-hook), Convolvulus 

simulans (bindweed), Apiastrum 

angustifolium (mock parsley), and 

Microseris douglasii ssp. platycarpha 

(small flowered microseris) (Bauder et 

al. 1994, pp. 9–10; McMillan 2006, p. 1; 

Vinje 2006b, pp. 1–2). 

In addition to the characteristics 

discussed above, the texture and 

structure of the clay lenses are essential 

for supporting the seedling 

establishment and growth of 

Acanthomintha ilicifolia. This soil 

provides many small pockets where 

seeds from A. ilicifolia become lodged 

as they fall from decomposing plants 

(Bauder and Sakrison 1999, p. 28). The 

seeds then stay in the soils until the 

temperatures become cooler in the 

winter months and the soil becomes 

saturated with the winter rains (Bauder 

and Sakrison 1997, p. 28). The seedlings 

then germinate and grow to mature 

plants. These plants do best when they 

are not crowded or shaded by other 

plants (Bauder and Sakrison 1999, p. 

12). The loose, crumbly texture of the 

soil provides the proper substrate to 

hold the seed bank and allow for root 

growth (PCE). 

Clay lenses generally form on gentle 

slopes. An analysis of 20 sites where 

Acanthomintha ilicifolia was observed 

found that the slopes range from 0 to 25 

degrees, with the majority of the sites 

having slopes below 20 degrees (Bauder 

et al. 1994, pp. 10–11) (PCE). This study 

also found that many thriving, natural 

populations were on slopes that faced 

southeast, south, southwest, and west, 

although not all sites fit this pattern 

(Bauder et al. 1994, pp. 10–11). Using 

GIS, we found that the known 

populations of Acanthomintha ilicifolia 

range in elevation from sea level to 

3,000 ft (914 m). Acanthomintha 

ilicifolia occurs on several soil types. 

These soils are mapped as Las Posas, 

Olivenhain, Redding, Huerhuero, 

Altamont, Cieneba, and Linne (Bowman 

1973, pp. 22–24, 38–40, 54–55, 61–64, 

67–68, and 71–72) and are derived from 

gabbro and soft calcareous sandstone 

substrates with a loose, crumbly 

structure and deep fissures that provide 

space for population and individual 

growth and substrate for seedling 

establishment. 

Water and Hydrology 

The loose, crumbly clay soils that 

support Acanthomintha ilicifolia act 

like a sponge and are saturated by 

winter rains. The saturation of these 

soils allows for seeds of A. ilicifolia to 

imbibe with water and germinate in the 

cool winter months (Bauder and 

Sakrison 1997, p. 32). As such, the 

species requires a natural hydrological 

regime to reproduce. Since we do not 

have specific information on the 

hydrological regime that this species 

requires, we did not include 

hydrological regime as a primary 

constituent element. 

Reproduction and Pollination 

The breeding system of 

Acanthomintha ilicifolia has not been 

studied, but it has been determined that 

other members of the genus 

Acanthomintha are self-compatible 

(Steeck 1995, pp. 27–33). A 1996 study 

(Bauder and Sakrison 1997, p. 38) found 

that several insect species visited the 

flowers and moved from plant to plant. 

These insects represented possible 

pollinators of A. ilicifolia; however, 

none were thought to represent speciesspecific pollinators (Bauder and 

Sakrison 1997, p. 39). Since we do not 

have information on any speciesspecific pollinators that visit A. 

ilicifolia, we did not include pollinators 

as a primary constituent element. 

Primary Constituent Elements for 

Acanthomintha ilicifolia 

Pursuant to our regulations, we are 

required to identify the known physical 

and biological features (PCEs) essential 

to the conservation of Acanthomintha 

ilicifolia. 

Based on our current knowledge of 

the life history, biology, and ecology of 

the species and the requirements of the 

habitat to sustain the essential life 

history functions of the species, we have 

determined that the PCE for 

Acanthomintha ilicifolia is: 

Clay lenses that provide substrate for 

seedling establishment and space for 

growth and development of 

Acanthomintha ilicifolia, that are: 

(a) Within chaparral and coastal sage 

scrub; 

(b) On gentle slopes ranging from 0 to 

25 degrees; 

(c) Derived from gabbro and soft 

calcareous sandstone substrates with a 

loose, crumbly structure and deep 

(approximately 2 feet (60 cm)) fissures; 

and 

(d) Characterized by a low density of 

forbs and geophytes, and a low density 

or absence of shrubs. 

This proposed designation is designed 

for the conservation of those areas 

containing the PCE necessary to support 

one or more of the species’ life history 

functions. All units and subunits in this 

proposed designation contain the PCE 

and support multiple life processes. 

This proposed rule would protect the 

PCE and thus the conservation function 

of the habitat. 

Criteria Used To Identify Critical 

Habitat 

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

the Act, we use the best scientific and 

commercial data available in 

determining areas that contain the 

features that are essential to the 

conservation of Acanthomintha 

ilicifolia. All of the areas proposed for 

designation are currently occupied by 

the species. Occupied areas were 

determined from survey data and 

element occurrence data in the CNDDB 

(CNDDB 2006). For the purpose of this 

proposal, we assumed that each element 

occurrence represents a population of A. 

ilicifolia, except in cases where there are 

several element occurrences located 

within 1 mile (1.6 km) of each other and 

the habitat is not fragmented by 

manmade features. In these cases, we 

considered the group of element 

occurrences as a single population. 

Examples of this include the 

Manchester Preserve in Encinitas 

(element occurrence (EO) 28, EO 42, and 

EO 54), McGinty Mountain near Jamul 

(EO 21, EO 22, and EO 30), and Viejas 

and Poser Mountains near Alpine (EO 

12, EO 50, EO 51, EO 62, EO 73, EO 74, 

and EO 75). 

We then identified the areas that 

contain the features that are essential to 

the conservation of A. ilicifolia by 

identifying areas that: (1) Support 

populations that occur on rare or unique 

habitat within the species’ range; (2) 

support the largest known populations 

of A. ilicifolia; or (3) support stable 

populations of A. ilicifolia. These 


cprice-sewell on PROD1PC66 with PROPOSALS2
Federal Register / Vol. 72, No. 49 / Wednesday, March 14, 2007 / Proposed Rules 11951 

criteria are explained in greater detail 

below. Areas containing the primary 

constituent elements and that meet at 

least one of the above criteria were 

considered for critical habitat 

designation. To evaluate locations 

occupied by this species we used: the 

California Natural Diversity Database 

(CNDDB 2006); a study by Bauder et al. 

(1994); biological surveys (City of San 

Diego 2000; City of San Diego 2001; City 

of San Diego 2003; City of San Diego 

2004; City of San Diego 2005; 

Conservation Biology Institute 2002, p. 

A3–1; County of San Diego 2002, p. 17; 

Dudek and Associates, Inc. 2006, 

Appendix A pp. 3–4; Helix 

Environmental Planning, Inc. 2002, p. 6; 

and REC Consultants, Inc. 2004, p. 

figure 5); and interviews with botanists 

working on this species (Kelley 2005; 

McMillan 2006). 

The first criterion we used to identify 

proposed critical habitat was areas that 

support populations that occur on rare 

or unique habitat within the species’

range. The majority of areas that 

currently support Acanthomintha 

ilicifolia are on dark brown to reddish 

brown clay soils that are derived from 

gabbro substrates. Historically, A. 

ilicifolia also occurred on gray clay soils 

that are derived from soft calcareous 

sandstone substrates. The only 

remaining population on this soil type 

is northeast of the intersection of 

Palomar Airport Road and El Camino 

Real, in the City of Carlsbad. Conserving 

unique soil types that this species 

occurs on will help to reduce the risk of 

extinction for this species because it 

may allow for the preservation of a 

greater amount of genetic diversity 

within the species’ gene pool. Therefore, 

this area containing population (EO 70) 

is proposed for critical habitat 

designation under criterion one. 

The second criterion we used to 

identify proposed critical habitat was 

areas that support the largest known 

populations of Acanthomintha ilicifolia. 

The CNDDB includes data for this 

species that date back to 1978. 

Populations of this species range from 

just a few individual plants to several 

thousand. The majority of the known 

populations range from 50 to 2,000 

plants. Yet, there are four populations 

that stand out as the largest, each having 

greater than 25,000 plants. The four 

largest populations and the estimated 

population at each location are: 

Sycamore Canyon (EO 32), 31,000 

plants; Slaughterhouse Canyon (EO 64), 

60,000 plants; Viejas and Poser 

Mountains (EO 12, EO 50, EO 51, EO 62, 

EO 73, and EO 74), 29,650 plants; and 

Hollenbeck Canyon (EO L), 100,000 

plants. These large populations are vital 

for the conservation of this species 

because they occur within large blocks 

of open space and are less likely to be 

impacted by edge effects associated with 

smaller populations in highly urbanized 

areas. Additionally, the conservation of 

these large populations will increase the 

persistence of the species across its 

range. Therefore, the area containing 

these populations is proposed for 

critical habitat designation under 

criterion two. These four populations 

represent approximately 75 percent of 

the total known plants of this species. 

The third criterion we used to identify 

proposed critical habitat was areas that 

support stable populations of 

Acanthomintha ilicifolia. For the 

purpose of this proposed critical habitat 

designation, we defined stable 

populations as those that contained 

more than 1,000 plants at least once 

during the period for which we have 

survey data. We evaluated the 

population data from the CNDDB and 

determined that populations with more 

than 1,000 plants at one time had the 

ability to rebound following years with 

low population numbers. Therefore, we 

considered populations with more than 

1,000 plants to have a high probability 

of persisting into the future and thus 

contribute to the conservation of the 

species. The locations of these 

populations are generally characterized 

by a series of clay lenses where the 

plants are found in a matrix of intact 

coastal sage scrub and chaparral. 

Although these areas are not free from 

exotic plant competitors, these 

populations have persisted over time 

without being out-competed by the 

exotic plant species present. This may 

be due in part to the low density of 

exotic plant species at these locations. 

In addition to all of the areas that meet 

criterion two, five other areas meet 

criterion three: the southeast portion of 

the City of Carlsbad (EO 47); the 

Manchester Preserve in Encinitas (EO 

28, EO 42, and EO 54); Los Pen ̃ asquitos 

Canyon (EO 19); Sabre Springs (EO 36); 

and McGinty Mountain in the southern 

part of San Diego County (EO 21, EO 22, 

and EO 30). Each of these areas provides 

habitat that consistently supports large 

populations of A. ilicifolia. Therefore, 

the area containing these populations is 

proposed for critical habitat designation 

under criterion three. 

The 10 areas that we identified as 

meeting the criteria for critical habitat 

contain the features that are essential for 

the conservation of this species. These 

areas support the only population of 

Acanthomintha ilicifolia on calcareous 

clay soil and the largest and most stable 

populations. These areas were mapped 

using data from field surveys and 

element occurrences in the CNDDB 

(CNDDB 2006), and unit boundaries 

were created using GIS. 

Annual plants experience annual 

fluctuation in population density and 

spatial distribution. Through the review 

of existing survey data and as a result 

of field work conducted by Service 

biologists, it appears that this holds true 

for Acanthomintha ilicifolia, as 

additional individuals are frequently 

located outside initially mapped 

occurrence areas (Bauder et al. 2004, pp. 

14–15; CNDDB 2006, pp. 11, 28–29, and 

70; Service unpublished data 2006). 

Because soil data are not available on a 

fine enough scale to ensure that 

proposed critical habitat included all 

occupied habitat, each area mapped for 

A. ilicifolia in the CNDDB was enlarged 

to include habitat within 500 ft (152 m) 

around the edge of mapped occurrences. 

Using aerial photography, we confirmed 

that no identifiable portion of an 

occupied clay lens appeared to have 

been inadvertently omitted and 

removed manmade features such as 

roads, buildings, parking lots and 

agricultural fields. This boundary was 

then used as our proposed critical 

habitat boundary. 

When determining proposed critical 

habitat boundaries within this proposed 

rule, we made every effort to avoid 

including developed areas such as lands 

covered by buildings, paved areas, and 

other structures that lack the PCE for 

Acanthomintha ilicifolia. The scale of 

the maps prepared under the parameters 

for publication within the Code of 

Federal Regulations may not reflect the 

exclusion of such developed areas. Any 

such structures and the land under them 

inadvertently left inside critical habitat 

boundaries shown on the maps of this 

proposed rule have been excluded by 

text in the proposed rule and are not 

proposed for designation as critical 

habitat. Therefore, Federal actions 

limited to these areas would not trigger 

section 7 consultation, unless they may 

affect the species or primary constituent 

elements in adjacent critical habitat. 

We are proposing to designate critical 

habitat on lands that we have 

determined were occupied at the time of 

listing that contain the PCE that 

supports life history functions essential 

for the conservation of the species and 

lands that were not known to be 

occupied at the time of listing, but that 

we have determined are essential to the 

conservation of the species. The lands 

that were not known to be occupied at 

the time of listing are all currently 

occupied and contain the PCE essential 

for the conservation of the species. The 

10 areas defined above, each 

representing one population, have been 


cprice-sewell on PROD1PC66 with PROPOSALS2
11952 Federal Register / Vol. 72, No. 49 / Wednesday, March 14, 2007 / Proposed Rules 

categorized into four units. Due to large 

amounts of area that did not contain the 

PCE in each of the four units, the units 

were further broken down into 17 

subunits so that the essential habitat 

could be accurately mapped and not 

include areas that do not have the PCE. 

These units/subunits are described in 

the Unit Descriptions section. 

Section 10(a)(1)(B) of the Act 

authorizes us to issue permits for the 

take of listed animal 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. While section 

10(a)(1)(B) of the Act does not cover 

take of listed plant species, HCPs often 

cover both listed animal and plant 

species. Acanthomintha ilicifolia is a 

covered species in approved subarea 

plans under two major HCPs, the San 

Diego Multiple Species Conservation 

Program (MSCP) and the San Diego 

Habitat Conservation Program (MHCP). 

We are proposing to exclude areas from 

the final designation of critical habitat 

where this species is covered by one of 

these HCPs. See the Exclusions under 

Section 4(b)(2) of the Act for a detailed 

discussion of these exclusions. We 

identify the areas proposed for 

exclusion in the discussion of 

individual critical habitat units below. 

Special Management Considerations or 

Protection 

When designating critical habitat, we 

assess whether the areas determined to 

be occupied at the time of listing 

contain primary constituent elements 

that may require special management 

considerations or protection. 

As stated in the final listing rule, 

threats to Acanthomintha ilicifolia 

include trampling and grazing, the 

presence of exotic plant species, offroad vehicles (ORVs), mining, and 

urbanization (63 FR 54938). Through 

our review of the existing data on A. 

ilicifolia, the threats listed in the final 

listing rule continue to impact this 

species and could impact the PCE as 

well. Building on the information 

contained in the final listing rule, data 

on the effects of competition from exotic 

plant species have been studied in 

greater detail (Bauder and Sakrison 

1999, pp. 6–19, 28–44) and attempts 

have been made to manage this threat 

(Kelly 2002, pp. 1–3). 

Urban development near 

Acanthomintha ilicifolia populations 

may alter the habitat characteristics 

required by the species. The destruction 

of habitat can change the slope and 

aspect of the site, making it 

uninhabitable for A. ilicifolia (PCE). The 

close proximity of development to 

populations of A. ilicifolia may affect 

other aspects of the site. For example, 

increased water runoff from 

developments may erode the clay lens 

and change the topography of the site 

(Bauder et al. 1994, p. 23) (PCE). 

The introduction of exotic plant 

species such as Centaurea melitensis 

can drastically change the species 

present in, and eliminate the open 

character of, the clay lens habitat (PCE). 

Centaurea melitensis has been shown, 

in field and greenhouse experiments, to 

negatively effect the biomass (growth) 

and seed production (reproduction) of 

Acanthomintha ilicifolia (Bauder and 

Sakrison 1999, p. 16). Populations of A. 

ilicifolia that are close to urbanized 

areas or in areas that have been heavily 

grazed generally have a high density of 

exotic plant species. In disturbed soils, 

C. melitensis is a common weed. When 

this and other exotic plant species 

become established they can outcompete A. ilicifolia for light, water, 

nutrients, and space. A. ilicifolia often 

grows larger and at a higher density 

when competition with exotic weeds is 

reduced (Bauder and Sakrison 1999, pp. 

12–16; Vinje 2007, p. 10). 

The final listing rule (63 FR 54938) 

discusses the impacts of ORV activity 

and trampling. In recent years the 

impacts associated with the use of 

mountain bikes has been observed to 

cause similar impacts (Vinje 2006a, p. 

1). Trampling, ORV activity, and 

mountain bike use outside of 

designated, maintained trails can 

compact the loose, crumbly soils (PCE). 

The repeated travel over a trail or track 

degrades the habitat of Acanthomintha 

ilicifolia in two ways: (1) by displacing 

soil; and (2) by compacting soil and 

reducing the amount of water that can 

percolate, thus reducing the plant’s 

ability to establish roots. 

Mining has been documented as a 

threat at two sites known to support 

Acanthomintha ilicifolia (63 FR 54938; 

Bauder et al. 1994, p. 17). Mining can 

alter many aspects of A. ilicifolia 

habitat. Heavy machinery can compact 

or remove clay lenses (PCE) or alter the 

slope of an area (PCE). The grading of 

large areas adjacent to A. ilicifolia 

habitat can make those areas vulnerable 

to invasion by exotic plant species and 

lead to the subsequent crowding and 

shading of A. ilicifolia habitat (PCE). All 

of these impacts may in turn lead to the 

disruption of the growth and 

reproduction of A. ilicifolia . 

Proposed Critical Habitat Designation 

We are proposing a total of 1,936 ac 

(783 ha) in four units as critical habitat 

for Acanthomintha ilicifolia . These four 

units are further subdivided into 17 

subunits. The critical habitat areas 

described below constitute our best 

assessment at this time of areas known 

to be occupied at the time of listing that 

contain the primary constituent 

elements that may require special 

management considerations or 

protection, and those additional areas 

that were not known to be occupied at 

the time of listing (subunits 3E and 4D), 

but are essential to the conservation of 

Acanthomintha ilicifolia . The four 

units proposed for designation as 

critical habitat are: (1) Unit 1: Northern 

San Diego County; (2) Unit 2: Central 

San Diego County; (3) Unit 3: Viejas 

Mountain and Poser Mountain, San 

Diego County; and (4) Unit 4: Southern 

San Diego County. We are proposing to 

exclude 1,302 ac (527 ha) under section 

4(b)(2) of the Act from the final 

designation of critical habitat. Table 1 

identifies the occupancy status for each 

subunit. Table 2 identifies the acreage 

and ownership of the areas being 

proposed as critical habitat and the 

areas proposed for exclusion from the 

final designation under section 4(b)(2) 

of the Act (see Relationship of Critical 

Habitat to Habitat Conservation Plan 

Lands—Exclusions Under Section 

4(b)(2) of the Act below for a detailed 

discussion).

Diego subarea plans of the San Diego MSCP. 

** Some columns may not sum exactly due to rounding of values. 

Below, we present brief descriptions 

of all units and subunits, and reasons 

why they meet the definition of critical 

habitat for Acanthomintha ilicifolia. The 

PCE in each subunit of critical habitat 

is threatened by the presence of exotic 

plants and recreational activities (e.g., 

trampling, erosion and soil compaction 

caused by hiking, off-road vehicle 

activity, and mountain biking); 

therefore, special management 

considerations or protections of the PCE 

is required to address these threats. 

Unit Descriptions 

Unit 1: Northern San Diego County 

Unit 1 consists of 253 ac (102 ha) in 

northern San Diego County divided into 

three subunits. This critical habitat unit 

includes habitat for Acanthomintha 

ilicifolia in the cities of Carlsbad and 

Encinitas under private, State, and local 

ownership (Table 1). The majority of 

habitat for A. ilicifolia in northern San 

Diego County is located in proximity to 

residential and commercial 

development; however, the habitat 

being proposed as critical habitat is 

mostly on land that has been set aside 

for the conservation of this and other 

species. This unit contains five element 

occurrences, all of which were known at 

the time of listing. The majority of the 

element occurrences in this unit are 

covered by the San Diego Multiple 

Habitat Conservation Program (MHCP). 

As part of the MHCP, each city will 

complete a subarea plan. At this time, 

the City of Carlsbad has completed its 

subarea plan under the San Diego 

MHCP and the City of Encinitas is 

nearing the completion of its subarea 

plan. We are proposing to exclude 172 

ac (70 ha) in the City of Carlsbad 

(portions of Subunit 1A and all of 

Subunit 1B) and the City of Encinitas 

(Subunit 1C) from the final designation 

of critical habitat based on protections 

afforded to A. ilicifolia under the 

Carlsbad and Encinitas subarea plans of 

the MHCP (see Relationship of Critical 

Habitat to Habitat Conservation Plan 

Lands—Exclusions Under Section 

4(b)(2) of the Act below for more 

information). The remaining 81 ac (33 

ha) in Subunit 1A is owned by the 

County of San Diego and is not part the 

San Diego MHCP. 

Subunit 1A, Palomar Airport (EO 70) 

Subunit 1A consists of 88 ac (36 ha) 

and was known to be occupied at the 

time of listing. This subunit contains 

several habitat patches known to 

support Acanthomintha ilicifolia and 

contains the feature (PCE) considered to 

be essential to the conservation of the 

species. The subunit meets our selection 

criteria because it supports a population 

on a unique soil type (criterion 1). This 

is the only area where A. ilicifolia is still 

known to occupy calcareous clay soils. 

The PCE in this subunit may require 

special management considerations or 

protection to control exotic plant 

species and reduce impacts associated 

with recreational activities. This subunit 

is within the designated preserve area 

for the Carlsbad subarea plan (referred 

to as the Carlsbad Habitat Management 

Plan (HMP)) of the San Diego MHCP; 

however, most of this subunit is owned 

by the County of San Diego and not a 

part of the Carlsbad HMP. The portion 

covered by the Carlsbad HMP will be 

managed for the conservation of this 

species. Therefore, we are proposing to 

exclude the 7 ac (3 ha) of this subunit 

that are covered by the Carlsbad HMP 

from the final designation of critical 

habitat (Table 1) (see Relationship of 

Critical Habitat to Habitat Conservation 

Plan Lands—Exclusions Under Section 

4(b)(2) of the Act below for more 

information). The remaining 81 ac (33 

ha) of land owned by the County of San 

Diego is proposed for inclusion in the 

designation of critical habitat. 

Subunit 1B, Southeast Carlsbad (EO 47) 

Subunit 1B consists of 73 ac (29 ha), 

was known to be occupied at the time 

of listing, and contains the feature (PCE) 

considered to be essential to the 

conservation of the species. The subunit 

meets our selection criteria because it 

supports a stable population (criterion 

3). This population was estimated to 

have 400 plants in 1989, 2,000 plants in 

1994, and 500 plants in 2006. The PCE 

in this subunit may require special 

management considerations or 

protection to control exotic plant 

species and reduce impacts associated 

with recreational activities. The 

majority of the lands within this subunit 

are within an area designated as a 

hardline conservation area (an area that 

has already been or is slated to be 

preserved) and the entire subunit is 

covered by the Carlsbad HMP of the San 

Diego MHCP which will provide 

substantial protection and management 

of the PCE essential to the conservation 

of Acanthomintha ilicifolia. Therefore, 

we are proposing to exclude this 

subunit from the final designation of 

critical habitat (Table 1) (see 

Relationship of Critical Habitat to 

Habitat Conservation Plan Lands—

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

Act below for more information). 

Subunit 1C, Manchester (EO 42, EO 28, 

and EO 54) 

Subunit 1C consists of 92 ac (37 ha), 

was known to be occupied at the time 

of listing, and contains the feature (PCE) 

considered to be essential to the 

conservation of the species. The subunit 

meets our selection criteria because it 

supports a stable population (criterion 

3). This population was estimated to 

have 5,000 plants in 1984, 300 plants in 

1985, 100 plants in 1986, 571 plants in 

1989, 2,000 plants in 1990, 4,000 plants 

in 1999, 5,000 plants in 1994, 3,000 

plants in 2005, and 500 plants in 2006. 

The PCE in this subunit may require 

special management considerations or 

protection to control exotic plant 

species and reduce impacts associated 

with recreational activities. 

Lands within this subunit are within 

a Focused Planning Area (core areas and 

linkages important for conservation of 

sensitive species) as designated under 

the City of Encinitas subarea plan of the 

San Diego MHCP. This plan indicates 

that the City of Encinitas will complete 

the HCP process under the San Diego 


cprice-sewell on PROD1PC66 with PROPOSALS2
Federal Register / Vol. 72, No. 49 / Wednesday, March 14, 2007 / Proposed Rules 11955 

MHCP and implement the conservation 

measures outlined for Acanthomintha 

ilicifolia. We are proposing to exclude 

all non-Federal lands in Subunit 1C 

covered by the City of Encinitas subarea 

plan of the San Diego MHCP from the 

final designation of critical habitat 

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

(Table 1) (see Relationship of Critical 

Habitat to Habitat Conservation Plan 

Lands—Exclusions Under Section 

4(b)(2) of the Act below for more 

information). However, since it is our 

understanding that little progress has 

been made by the City of Encinitas to 

finalize their subarea plan since the 

2001 release of the draft plan, we are 

seeking public comment on our 

proposed exclusion (see Public 

Comments Solicited section above). 

Based on information received during 

the public comment period, the 

Secretary may determine that sufficient 

progress has not been made and that 

lands within the City of Encinitas’

subarea plan should not be excluded 

from the final designation of critical 

habitat. 

Unit 2: Central San Diego County 

Unit 2 consists of 497 ac (201 ha) 

divided into four subunits. This unit is 

located in central San Diego County. 

This critical habitat unit includes 

habitat for Acanthomintha ilicifolia in 

the City of San Diego and in portions of 

unincorporated County of San Diego 

under private, State, and local 

ownership (Table 1). The majority of 

habitat for A. ilicifolia in Unit 2 is 

located within preserves and open 

space; however, the PCE in this unit 

may require special management 

considerations or protection to control 

exotic plant species and reduce impacts 

associated with recreational activities. 

All of the element occurrences included 

in Unit 2 are protected under the 

approved City of San Diego and County 

of San Diego subarea plans under the 

San Diego Multiple Species 

Conservation Program (MSCP); 

therefore, we are proposing to exclude 

all four subunits from the final 

designation of critical habitat (see 

Relationship of Critical Habitat to 

Habitat Conservation Plan Lands—

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

Act below for more information). 

Subunit 2A, Pen ̃ asquitos Canyon (EO 

19) 

Subunit 2A consists of 63 ac (25 ha), 

was known to be occupied at the time 

of listing, and contains the feature (PCE) 

considered to be essential to the 

conservation of the species. The subunit 

meets our selection criteria because it 

supports a stable population (criterion 

3). This population was estimated to 

have 1,000 plants in 1986, 740 plants in 

1990, 14 plants in 1991, 36 plants in 

1992, 1,800 plants in 1994, 1,053 plants 

in 2000, 601 plants in 2001, 0 plants in 

2002, 726 plants in 2003, 501 plants in 

2004, and 2,091 plants in 2005. The PCE 

in this subunit may require special 

management considerations or 

protection to control exotic plant 

species and reduce impacts associated 

with recreational activities. This area is 

covered under the City of San Diego 

subarea plan of the San Diego MSCP 

and is within an area designated as a 

hardline conservation area. Therefore, 

we are proposing to exclude this area 

from the final designation of critical 

habitat (Table 1) (see Relationship of 

Critical Habitat to Habitat Conservation 

Plan Lands—Exclusions Under Section 

4(b)(2) of the Act below for more 

information). 

Subunit 2B, Sabre Springs (EO 36) 

Subunit 2B consists of 52 ac (22 ha), 

was known to be occupied at the time 

of listing, and contains the feature (PCE) 

considered to be essential to the 

conservation of the species. The subunit 

meets our selection criteria because it 

supports a stable population (criterion 

3). This population was estimated to 

have 5,970 plants in 1989, 2,900 plants 

in 1990, 7,000 plants in 1992, 16,400 

plants in 1994, 3,858 plants in 2000, 

2,832 plants in 2001, 250 plants in 2002, 

19,721 plants in 2003, 17,085 plants in 

2004, 13 plants in 2005, and 150 plants 

in 2006. The PCE in this subunit may 

require special management 

considerations or protection to control 

exotic plant species and reduce impacts 

associated with recreational activities. 

This area is covered under the City of 

San Diego subarea plan of the San Diego 

MSCP and is within an area designated 

as a hardline conservation area. 

Therefore, we are proposing to exclude 

this area from the final designation of 

critical habitat (Table 1) (see 

Relationship of Critical Habitat to 

Habitat Conservation Plan Lands—

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

Act below for more information). 

Subunit 2C, Sycamore Canyon (EO 32) 

Subunit 2C consists of 306 ac (144 

ha), was known to be occupied at the 

time of listing, and contains the feature 

(PCE) considered to be essential to the 

conservation of the species. The subunit 

meets our selection criteria because it is 

one of the largest recorded populations 

of Acanthomintha ilicifolia and it 

supports a stable population (criteria 2 

and 3). This population was estimated 

to have 3,000 plants in 1986, 200 plants 

in 1989, 8,800 plants in 1992, and 

31,000 plants in 1994. The PCE in this 

subunit may require special 

management considerations or 

protection to control exotic plant 

species and reduce impacts associated 

with recreational activities. In the San 

Diego MSCP analysis, this area was 

recognized as one of eight ‘‘major 

populations.’’ This area is covered 

under the County of San Diego subarea 

plan of the San Diego MSCP and is 

within an area designated as a hardline 

conservation area; therefore, we are 

proposing to exclude this area from the 

final designation of critical habitat 

(Table 1) (see Relationship of Critical 

Habitat to Habitat Conservation Plan 

Lands—Exclusions Under Section 

4(b)(2) of the Act below for more 

information). 

Subunit 2D, Slaughterhouse Canyon (EO 

64) 

Subunit 2D consists of 77 ac (31 ha), 

was known to be occupied at the time 

of listing, and contains the feature (PCE) 

considered to be essential to the 

conservation of the species. The subunit 

meets our selection criteria because it 

supports one of the largest recorded 

populations of Acanthomintha ilicifolia 

(criterion 2). This population was 

estimated to have 60,000 plants in 1993. 

The PCE in this subunit may require 

special management considerations or 

protection to control exotic plant 

species and reduce impacts associated 

with recreational activities. In the San 

Diego MSCP analysis, this area was 

recognized as one of eight major 

populations. The element occurrence of 

A. ilicifolia at this site is on open space 

adjacent to a sand and gravel mining 

operation. This element occurrence is 

covered under the County of San Diego 

subarea plan of the San Diego MSCP. 

Therefore, we are proposing to exclude 

this area from the final designation of 

critical habitat (Table 1) (see 

Relationship of Critical Habitat to 

Habitat Conservation Plan Lands—

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

Act below for more information). 

Unit 3: Viejas Mountain and Poser 

Mountain 

Unit 3 consists of 837 ac (339 ha) 

divided into six subunits in interior San 

Diego County. This critical habitat unit 

includes habitat for Acanthomintha 

ilicifolia in the City of Alpine and in the 

Cleveland National Forest on Viejas and 

Poser Mountains. The majority of 

habitat for A. ilicifolia in this unit is 

located on land managed by the U.S. 

Forest Service (USFS) (Table 1). The 

element occurrences that are on Viejas 

and Poser Mountains are interspersed in 

clay patches in a mosaic of relatively 


cprice-sewell on PROD1PC66 with PROPOSALS2
11956 Federal Register / Vol. 72, No. 49 / Wednesday, March 14, 2007 / Proposed Rules 

undisturbed habitat. Due to the 

proximity of these element occurrences 

and the fact that the habitat is not 

fragmented by any manmade barriers, 

these element occurrences are 

considered to be a single population of 

A. ilicifolia. This unit is proposed for 

critical habitat designation because it 

supports one of the largest recorded 

populations of the species (criterion 2). 

This population is estimated to have 

greater than 30,000 plants based on the 

maximum number of plants observed at 

the different element occurrences (EO 

12, 6,650 plants in 1991; EO 50, 5,600 

plants in 1994; EO 51, 8,300 plants in 

2003; EO 62, 1,115 plants in 2000; EO 

73, 8,750 plants in 1997; and EO 74, 

2,000 plants in 2000). The PCE in this 

unit may require special management to 

control exotic plant species. This unit 

has some areas that are protected as part 

of the San Diego MSCP. We are 

proposing to exclude non-Federal lands 

covered by the County of San Diego 

subarea plan of the San Diego MSCP in 

this unit (284 ac (115 ha)) from the final 

designation of critical habitat (Table 1) 

(see Relationship of Critical Habitat to 

Habitat Conservation Plan Lands—

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

Act below for more information). 

Subunit 3A, Viejas Mountain (EO 73) 

Subunit 3A consists of 33 ac (13 ha), 

was known to be occupied at the time 

of listing, and contains the feature (PCE) 

considered to be essential to the 

conservation of the species. Subunit 3A 

is privately owned and covered by the 

County of San Diego subarea plan of the 

San Diego MSCP (33 ac (13 ha)). The 

PCE in this subunit may require special 

management considerations or 

protection to control exotic plant 

species and reduce impacts associated 

with recreational activities. Because the 

County of San Diego subarea plan 

provides for the conservation of 

Acanthomintha ilicifolia and this 

subunit is within a hardline 

conservation area, we are proposing to 

exclude all of this subunit from the final 

designation of critical habitat (Table 1) 

(see Relationship of Critical Habitat to 

Habitat Conservation Plan Lands—

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

Act below for more information). 

Subunit 3B, Viejas Mountain (EO 50) 

Subunit 3B consists of 208 ac (84 ha), 

was known to be occupied at the time 

of listing, and contains the feature (PCE) 

considered to be essential to the 

conservation of the species. Subunit 3B 

includes land managed by the USFS and 

land under private ownership. The 

privately owned land is covered by the 

County of San Diego subarea plan of the 

San Diego MSCP (156 ac (63 ha)). The 

PCE in this subunit may require special 

management considerations or 

protection to control exotic plant 

species and reduce impacts associated 

with recreational activities. Because the 

County of San Diego subarea plan 

provides for the conservation of 

Acanthomintha ilicifolia, we are 

proposing to exclude the portion of this 

subunit on private land from the final 

designation of critical habitat (Table 1) 

(see Relationship of Critical Habitat to 

Habitat Conservation Plan Lands—

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

Act below for more information). The 

remaining 52 ac (21 ha) of federally 

owned land is proposed for inclusion in 

the designation of critical habitat. 

Subunit 3C, Viejas Mountain (EO 51) 

Subunit 3C consists of 318 ac (129 

ha), was known to be occupied at the 

time of listing, and contains the feature 

(PCE) considered to be essential to the 

conservation of the species. Subunit 3C 

includes land managed by the USFS and 

land under private ownership. The 

privately owned land is covered by the 

County of San Diego subarea plan of the 

San Diego MSCP (38 ac (15 ha)), some 

of which falls within a hardline 

conservation area. The PCE in this 

subunit may require special 

management considerations or 

protection to control exotic plant 

species and reduce impacts associated 

with recreational activities. Because the 

County of San Diego subarea plan 

provides for the conservation of 

Acanthomintha ilicifolia, we are 

proposing to exclude the portion of this 

subunit on private land from the final 

designation of critical habitat (Table 1) 

(see Relationship of Critical Habitat to 

Habitat Conservation Plan Lands—

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

Act below for more information). The 

remaining 280 ac (113 ha) of federally 

owned land is proposed for inclusion in 

the designation of critical habitat. 

Subunit 3D, Viejas Mountain (EO 62) 

Subunit 3D consists of 82 ac (33 ha), 

was known to be occupied at the time 

of listing, and contains the feature (PCE) 

considered to be essential to the 

conservation of the species. Subunit 3D 

includes land managed by the USFS and 

land under private ownership. The 

privately owned land is covered by the 

County of San Diego subarea plan of the 

San Diego MSCP (50 ac (20 ha)), some 

of which falls within a hardline 

conservation area. The PCE in this 

subunit may require special 

management considerations or 

protection to control exotic plant 

species and reduce impacts associated 

with recreational activities. Because the 

County of San Diego subarea plan 

provides for the conservation of 

Acanthomintha ilicifolia, we are 

proposing to exclude the portion of this 

subunit on private land from the final 

designation of critical habitat (Table 1) 

(see Relationship of Critical Habitat to 

Habitat Conservation Plan Lands—

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

Act below for more information). The 

remaining 32 ac (13 ha) of federally 

owned land is proposed for inclusion in 

the designation of critical habitat. 

Subunit 3E, Poser Mountain (EO 74) 

Subunit 3E consists of 34 ac (14 ha) 

and was not known to be occupied at 

the time of listing; however, this area is 

currently occupied and contains the 

PCE. This area containing population 

(EO 74) is essential to the conservation 

of Acanthomintha ilicifolia because it 

meets criterion 2 for designation of 

critical habitat in that it is a portion of 

the four largest known populations of A. 

ilicifolia. Based on our analysis of 

reported density estimates, this subunit 

contains approximately 6 percent of 

individuals in the greater Poser and 

Viejas Mountain population. In 2000, 

when this population was discovered, it 

totaled 2,000 plants. This subunit is on 

land managed by the USFS. No 

exclusions are proposed for this 

subunit. Therefore, 34 ac (14 ha) of 

federally owned land is proposed for 

inclusion in the final designation of 

critical habitat. 

Subunit 3F, Poser Mountain (EO 12) 

Subunit 3F consists of 163 ac (66 ha), 

was known to be occupied at the time 

of listing, and contains the feature (PCE) 

considered to be essential to the 

conservation of the species. Subunit 3F 

includes land managed by the USFS and 

land under private ownership. The 

privately owned land is covered by the 

County of San Diego subarea plan of the 

San Diego MSCP (7 ac (3 ha)), some of 

which falls within a hardline 

conservation area. The PCE in this unit 

may require special management 

considerations or protection to control 

exotic plant species and reduce impacts 

associated with recreational activities. 

Because the County of San Diego 

subarea plan provides for the 

conservation of Acanthomintha 

ilicifolia, we are proposing to exclude 

the portion of this subunit on private 

land from the final designation of 

critical habitat (Table 1) (see 

Relationship of Critical Habitat to 

Habitat Conservation Plan Lands—

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

Act below for more information). The 

remaining 156 ac (63 ha) of federally 


cprice-sewell on PROD1PC66 with PROPOSALS2
Federal Register / Vol. 72, No. 49 / Wednesday, March 14, 2007 / Proposed Rules 11957 

owned land is proposed for inclusion in 

the designation of critical habitat. 

Unit 4: Southern San Diego County 

Unit 4 consists of 351 ac (142 ha) 

divided into four subunits in southern 

San Diego County. This critical habitat 

unit includes habitat for Acanthomintha 

ilicifolia near the City of Jamul in the 

southern portion of the unincorporated 

County of San Diego that is under 

private, State, and local ownership 

(Table 1). The habitat for A. ilicifolia in 

southern San Diego County is located in 

proximity to rural residential 

development and in relatively 

undeveloped areas. This unit has many 

element occurrences that are protected 

as part of the San Diego MSCP and 

included in the subarea plan for the 

County of San Diego. All of the land 

proposed for critical habitat in this unit 

is covered by this subarea plan. 

Therefore, we propose to exclude all 

four subunits covered by the San Diego 

MSCP from the final designation of 

critical habitat (see Relationship of 

Critical Habitat to Habitat Conservation 

Plan Lands—Exclusions Under Section 

4(b)(2) of the Act below for more 

information). 

Subunits 4A, 4B, and 4C, McGinty 

Mountain (EO 21, EO 22, and EO 30) 

Subunits 4A, 4B, and 4C consist of 

265 ac (107 ha), were known to be 

occupied at the time of listing, and 

contain the feature (PCE) considered to 

be essential to the conservation of the 

species. These sites include three 

element occurrences occupied by 

Acanthomintha ilicifolia on McGinty 

Mountain, and due to the proximity of 

these element occurrences, they are 

considered to be a single population. 

This population was estimated to have 

1,200 plants in 1986, and 2,625 plants 

in 1994. The PCE in this unit may 

require special management 

considerations or protection to control 

exotic plant species and reduce impacts 

associated with recreational activities. 

In the San Diego MSCP analysis, this 

area was considered one of eight major 

populations discussed in the plan. This 

population is included in the County of 

San Diego subarea plan of the San Diego 

MSCP and is within an area designated 

as a hardline conservation area. 

Therefore, we are proposing to exclude 

the entirety of these subunits from the 

final designation of critical habitat 

(Table 1) (see Relationship of Critical 

Habitat to Habitat Conservation Plan 

Lands—Exclusions Under Section 

4(b)(2) of the Act below for more 

information). 

Subunit 4D, Hollenbeck Canyon (EO L) 

Subunit 4D consists of 84 ac (34 ha) 

and was not known to be occupied at 

the time of listing; however it is 

currently occupied and contains the 

PCE. This site is on the Hollenbeck 

Canyon Wildlife Area, a preserve owned 

and managed by the California 

Department of Fish and Game. This area 

is essential to the conservation of the 

species because it meets criterion 2 for 

designation of critical habitat in that it 

contains approximately 100,000 plants, 

the largest known population of 

Acanthomintha ilicifolia; almost twice 

as large as the next largest population at 

Slaughterhouse Canyon (EO 64), that 

has 60,000 plants. The population in 

this subunit was estimated to contain 

30,000 plants in 2002 which suggests 

active recruitment at this location. This 

population is included in the County of 

San Diego subarea plan of the San Diego 

MSCP and the majority of the subunit is 

within an area designated as a hardline 

conservation area. Therefore, we are 

proposing to exclude all of this subunit 

from the final designation of critical 

habitat (Table 1) (see Relationship of 

Critical Habitat to Habitat Conservation 

Plan Lands—Exclusions Under Section 

4(b)(2) of the Act below for more 

information). 

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 402.02, we define 

destruction or adverse modification as 

‘‘a direct or indirect alteration that 

appreciably diminishes the value of 

critical habitat for both the survival and 

recovery of a listed species. Such 

alterations include, but are not limited 

to, alterations adversely modifying any 

of those physical or biological features 

that were the basis for determining the 

habitat to be critical.’’ However, recent 

decisions by the 5th and 9th Circuit 

Court of Appeals have invalidated this 

definition (see Gifford Pinchot Task 

Force v. U.S. Fish and Wildlife Service, 

378 F. 3d 1059 (9th Cir 2004) and Sierra 

Club v. U.S. Fish and Wildlife Service, 

245 F.3d 434, 442F (5th Cir 2001)). 

Pursuant to current national policy and 

the statutory provisions of the Act, 

destruction or adverse modification is 

determined on the basis of whether, 

with implementation of the proposed 

Federal action, the affected critical 

habitat would remain functional (or 

retain the current ability for the primary 

constituent elements to be functionally 

established) to serve the intended 

conservation role for the species. 

Section 7(a) of the Act requires 

Federal agencies, including the Service, 

to evaluate their actions with respect to 

any species that is proposed or listed as 

endangered or threatened and with 

respect to its critical habitat, if any is 

proposed or designated. Regulations 

implementing this interagency 

cooperation provision of the Act are 

codified at 50 CFR part 402. 

Section 7(a)(4) of the Act requires 

Federal agencies to confer with us on 

any action that is likely to jeopardize 

the continued existence of a species 

proposed for listing or result in 

destruction or adverse modification of 

proposed critical habitat. This is a 

procedural requirement only. However, 

once a proposed species becomes listed, 

or proposed critical habitat is 

designated as final, the full prohibitions 

of section 7(a)(2) of the Act apply to any 

Federal action. The primary utility of 

the conference procedures is to 

maximize the opportunity for a Federal 

agency to adequately consider proposed 

species and critical habitat and avoid 

potential delays in implementing their 

proposed action as a result of the 

section 7(a)(2) compliance process, 

should those species be listed or the 

critical habitat designated. 

Under conference procedures, the 

Service may provide advisory 

conservation recommendations to assist 

the agency in eliminating conflicts that 

may be caused by the proposed action. 

The Service may conduct either 

informal or formal conferences. Informal 

conferences are typically used if the 

proposed action is not likely to have any 

adverse effects to the proposed species 

or proposed critical habitat. Formal 

conferences are typically used when the 

Federal agency or the Service believes 

the proposed action is likely to cause 

adverse effects to proposed species or 

critical habitat, inclusive of those that 

may cause jeopardy or adverse 

modification. 

The results of an informal conference 

are typically transmitted in a conference 

report, while the results of a formal 

conference are typically transmitted in a 

conference opinion. Conference 

opinions on proposed critical habitat are 

typically prepared according to 50 CFR 

402.14, as if the proposed critical 

habitat were designated. We may adopt 

the conference opinion 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)). As noted above, any 

conservation recommendations in a 


cprice-sewell on PROD1PC66 with PROPOSALS2
11958 Federal Register / Vol. 72, No. 49 / Wednesday, March 14, 2007 / Proposed Rules 

conference report or opinion are strictly 

advisory. 

If a species is listed or critical habitat 

is designated, section 7(a)(2) of the Act 

requires Federal agencies to ensure that 

activities they authorize, fund, or carry 

out are not likely to jeopardize the 

continued existence of 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. As a result of this 

consultation, compliance with the 

requirements of section 7(a)(2) of the 

Act will be documented through the 

Service’s issuance of: (1) A concurrence 

letter for Federal actions that may affect, 

but are not likely to adversely affect, 

listed species or critical habitat; or (2) a 

biological opinion for Federal actions 

that are likely to adversely affect listed 

species or critical habitat. 

When we issue a biological opinion 

concluding that a project is likely to 

result in jeopardy to a listed species or 

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 jeopardy to the listed 

species or 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 certain instances, including 

where a new species is listed or critical 

habitat is subsequently designated that 

may be affected by the Federal action, 

where 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 with us on actions for 

which formal consultation has been 

completed, if those actions may affect 

subsequently listed species or 

designated critical habitat or adversely 

modify or destroy proposed critical 

habitat. 

Federal activities that may affect 

Acanthomintha ilicifolia or its 

designated critical habitat will require 

section 7 consultation under the Act. 

Activities on State, Tribal, local, or 

private lands requiring a Federal permit 

(such as a permit from the Army Corps 

of Engineers under section 404 of the 

Clean Water Act or a permit under 

section 10(a)(1)(B) of the Act from the 

Service) or involving some other Federal 

action (such as funding from the Federal 

Highway Administration, Federal 

Aviation Administration, or the Federal 

Emergency Management Agency) will 

also be subject to the section 7 

consultation process. Federal actions 

not affecting listed species or critical 

habitat, and actions on State, Tribal, 

local, or private lands that are not 

federally funded, authorized, or 

permitted, do not require section 7 

consultations. 

Application of the Jeopardy and 

Adverse Modification Standards for 

Actions Involving Effects to 

Acanthomintha ilicifolia and Its Critical 

Habitat 

Jeopardy Standard 

The Service applies an analytical 

framework for Acanthomintha ilicifolia 

jeopardy analyses that relies heavily on 

the importance of core area populations 

to the survival and recovery of A. 

ilicifolia. The section 7(a)(2) analysis is 

focused not only on these populations 

but also on the habitat conditions 

necessary to support them. 

The jeopardy analysis usually 

expresses the survival and recovery 

needs of Acanthomintha ilicifolia in a 

qualitative fashion without making 

distinctions between what is necessary 

for survival and what is necessary for 

recovery. Generally, if a proposed 

Federal action is incompatible with the 

viability of the affected core area 

population(s), inclusive of associated 

habitat conditions, a jeopardy finding is 

considered to be warranted because of 

the relationship of each core area 

population to the survival and recovery 

of the species as a whole. 

Adverse Modification Standard 

If this proposal is adopted, the 

analytical framework described in the 

Director’s December 9, 2004, 

memorandum will be used to complete 

section 7(a)(2) analyses for Federal 

actions affecting Acanthomintha 

ilicifolia critical habitat. The key factor 

related to the adverse modification 

determination is whether, with 

implementation of the proposed Federal 

action, the affected critical habitat 

would remain functional (or retain the 

current ability for the primary 

constituent elements to be functionally 

established) to serve the intended 

conservation role for the species. 

Generally, the conservation role of A. 

ilicifolia critical habitat units is to 

support viable core area populations. 

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 species. 

Activities that may destroy or 

adversely modify critical habitat are 

those that alter the PCE to an extent that 

the conservation value of critical habitat 

for Acanthomintha ilicifolia is 

appreciably reduced. Activities that, 

when carried out, funded, or authorized 

by a Federal agency, may affect critical 

habitat and therefore result in 

consultation for A. ilicifolia include, but 

are not limited to: 

(1) Actions that would disturb or 

remove the clay soils within a subunit 

of critical habitat. Such activities could 

include, but are not limited to, clearing 

areas for development and roads, 

creation of trails, and installation of 

pipelines or other underground 

infrastructure. These activities could 

eliminate or reduce the habitat 

necessary for the growth and 

reproduction of Acanthomintha 

ilicifolia. 

(2) Actions that would introduce 

exotic plant species or alter the natural 

habitat in a way that increases the 

likelihood for the invasion of exotic 

plant species. Such activities could 

include, but are not limited to, the 

introduction of fill dirt to development 

sites adjacent to Acanthomintha 

ilicifolia critical habitat, grading areas 

for agriculture, clearing native 

vegetation, and the use of mountain 

bikes and off-highway vehicles. These 

activities could create space for 

populations of exotic plants to grow and 

then invade A. ilicifolia habitat or bring 

the seeds of exotic plants into A. 

ilicifolia habitat, thus filling the open 

space needed for the growth and 

reproduction of this species with exotic 

plant competitors. 

(3) Actions that would alter the 

hydrology of critical habitat subunits. 

Such activities could include, but are 

not limited to, runoff from developed 

streets, runoff from irrigated landscapes, 

and increased flow or erosion from 


cprice-sewell on PROD1PC66 with PROPOSALS2
Federal Register / Vol. 72, No. 49 / Wednesday, March 14, 2007 / Proposed Rules 11959 

storm drains. These activities could 

alter the timing and amount of water 

that Acanthomintha ilicifolia plants 

receive, altering their phenology and 

fecundity. These activities could also 

cause the erosion of the clay soils that 

are necessary for the growth of A. 

ilicifolia. 

We consider all of the units proposed 

as critical habitat, as well as those that 

have been proposed for exclusion from 

the final designation, to contain features 

essential to the conservation of 

Acanthomintha ilicifolia. All units are 

within the geographic range of the 

species, all units except 3E and 4D were 

occupied by the species at the time of 

listing, and all units are currently 

occupied (based on observations made 

within the last 15 years). Federal 

agencies already consult with us on 

activities in areas currently occupied by 

A. ilicifolia, or if the species may be 

affected by the action, to ensure that 

their actions do not jeopardize the 

continued existence of A. ilicifolia. 

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

Act 

There are multiple ways to provide 

management or protection for species’

habitat. Statutory and regulatory 

frameworks that exist at a local level can 

provide protection or management, as 

can lack of pressure for change, such as 

areas too remote for anthropogenic 

disturbance. Finally, State, local, or 

private management plans, as well as 

management under Federal agencies’

jurisdictions, can provide protection or 

management that may lessen or even 

eliminate any appreciable benefit to a 

designation of critical habitat. When we 

consider a plan to determine its 

adequacy in protecting habitat, we 

consider whether the plan, as a whole, 

will provide the same level of protection 

that designation of critical habitat 

would provide. The plan need not lead 

to exactly the same result as a 

designation in every individual 

application, as long as the protection it 

provides is equivalent, overall. In 

making this determination, we examine 

whether the plan provides management, 

protection, or enhancement of the PCEs 

that is at least equivalent to that 

provided by a critical habitat 

designation, and whether there is a 

reasonable expectation that the 

management, protection, or 

enhancement actions will continue into 

the foreseeable future. Each review is 

particular to the species and the plan, 

and some plans may be adequate for 

some species and inadequate for others. 

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. The 

Secretary may exclude an area from 

critical habitat if he determines that the 

benefits of such exclusion outweigh the 

benefits of specifying such area as part 

of the critical habitat, unless he 

determines, based on the best scientific 

data available, that the failure to 

designate such area as critical habitat 

will result in the extinction of the 

species. In making that determination, 

the Secretary is afforded broad 

discretion, and the Congressional record 

is clear that in making a determination 

under the section the Secretary has 

discretion as to which factors to use and 

how much weight will be given to any 

factor. 

Under section 4(b)(2) of the Act, in 

considering whether to exclude a 

particular area from the designation, we 

must identify the benefits of including 

the area in the designation, identify the 

benefits of excluding the area from the 

designation, and determine whether the 

benefits of exclusion outweigh the 

benefits of inclusion. If an exclusion is 

contemplated, then we must determine 

whether excluding the area would result 

in the extinction of the species. In the 

following sections, we address a number 

of general issues that are relevant to the 

exclusions we considered. In addition, 

the Service is conducting an economic 

analysis of the impacts of the proposed 

critical habitat designation and related 

factors, which will be available for 

public review and comment. Based on 

public comment on that document, the 

proposed designation itself, and the 

information in the final economic 

analysis, areas in addition to those 

proposed for exclusion here may be 

excluded from critical habitat by the 

Secretary under the provisions of 

section 4(b)(2) of the Act. This is 

provided for in the Act, and in our 

implementing regulations at 50 CFR 

424.19. 

Conservation Partnerships on NonFederal Lands 

Most federally listed species in the 

United States will not recover without 

the cooperation of non-Federal 

landowners. More than 60 percent of the 

United States is privately owned 

(National Wilderness Institute 1995), 

and at least 80 percent of endangered or 

threatened species occur either partially 

or solely on private lands (Crouse et al. 

2002). Stein et al. (1995) found that only 

about 12 percent of listed species were 

found almost exclusively on Federal 

lands (90–100 percent of their known 

occurrences restricted to Federal lands) 

and that 50 percent of federally listed 

species are not known to occur on 

Federal lands at all. 

Given the distribution of listed 

species with respect to land ownership, 

conservation of listed species in many 

parts of the United States is dependent 

upon working partnerships with a wide 

variety of entities and the voluntary 

cooperation of many non-Federal 

landowners (Wilcove and Chen 1998; 

Crouse et al. 2002; James 2002). 

Building partnerships and promoting 

voluntary cooperation of landowners is 

essential to understanding the status of 

species on non-Federal lands and is 

necessary to implement recovery actions 

such as reintroducing listed species, 

habitat restoration, and habitat 

protection. 

Many non-Federal landowners derive 

satisfaction in contributing to 

endangered species recovery. The 

Service promotes these private-sector 

efforts through the Four Cs 

philosophy—conservation through 

communication, consultation, and 

cooperation. This philosophy is evident 

in Service programs such as HCPs, Safe 

Harbor Agreements, Candidate 

Conservation Agreements, Candidate 

Conservation Agreements with 

Assurances, and conservation challenge 

cost-share. Many private landowners, 

however, are wary of the possible 

consequences of encouraging 

endangered species to their property, 

and there is mounting evidence that 

some regulatory actions by the Federal 

government, while well-intentioned and 

required by law, can under certain 

circumstances have unintended 

negative consequences for the 

conservation of species on private lands 

(Wilcove et al. 1996; Bean 2002; Conner 

and Mathews 2002; James 2002; Koch 

2002, Brook et al. 2003). Many 

landowners fear a decline in their 

property value due to real or perceived 

restrictions on land-use options where 

threatened or endangered species are 

found. Consequently, harboring 

endangered species is viewed by many 

landowners as a liability, resulting in 

anti-conservation incentives because 

maintaining habitats that harbor 

endangered species represents a risk to 

future economic opportunities (Main et 

al. 1999; Brook et al. 2003). 

The purpose of designating critical 

habitat is to contribute to the 

conservation of threatened and 

endangered species and the ecosystems 

upon which they depend. The outcome 

of the designation, triggering regulatory 

requirements for actions funded, 

authorized, or carried out by Federal 

agencies under section 7 of the Act, can 


cprice-sewell on PROD1PC66 with PROPOSALS2
11960 Federal Register / Vol. 72, No. 49 / Wednesday, March 14, 2007 / Proposed Rules 

sometimes be counterproductive to its 

intended purpose on non-Federal lands. 

According to some researchers, the 

designation of critical habitat on private 

lands significantly reduces the 

likelihood that landowners will support 

and carry out conservation actions 

(Main et al. 1999; Bean 2002; Brook et 

al. 2003). The magnitude of this 

negative outcome is greatly amplified in 

situations where active management 

measures (e.g., reintroduction, fire 

management, control of invasive 

species) are necessary for species 

conservation (Bean 2002). The Service 

believes that the judicious exclusion of 

specific areas of non-federally owned 

lands from critical habitat designation 

can contribute to species recovery and 

provide a superior level of conservation 

than critical habitat alone. 

The Department of Interior’s 

Cooperative Conservation philosophy is 

the foundation for developing the tools 

of conservation. These tools include 

conservation grants, funding for 

Partners for Fish and Wildlife Program, 

the Coastal Program, and cooperativeconservation challenge cost-share 

grants. Our Private Stewardship Grant 

program and Landowner Incentive 

Program provide assistance to private 

landowners in their voluntary efforts to 

protect threatened, imperiled, and 

endangered species, including the 

development and implementation of 

HCPs. 

Conservation agreements with nonFederal landowners (e.g., HCPs, 

contractual conservation agreements, 

easements, and stakeholder-negotiated 

State regulations) enhance species 

conservation by extending protections 

for species beyond those available 

through section 7 consultations. In the 

past decade, we have encouraged nonFederal landowners to enter into 

conservation agreements, based on a 

view that we can achieve greater species 

conservation on non-Federal land 

through such partnerships than we can 

through coercive methods (61 FR 63854; 

December 2, 1996). 

General Principles of Section 7 

Consultations Used in the 4(b)(2) 

Balancing Process 

The most direct, and potentially 

largest, regulatory benefit of critical 

habitat is that federally authorized, 

funded, or carried out activities require 

consultation pursuant to section 7 of the 

Act to ensure that they are not likely to 

destroy or adversely modify critical 

habitat. There are two limitations to this 

regulatory effect. First, it only applies 

where there is a Federal nexus—if there 

is no Federal nexus—designation itself 

does not restrict actions that destroy or 

adversely modify critical habitat. 

Second, it only limits destruction or 

adverse modification. By its nature, the 

prohibition on adverse modification is 

designed to ensure those areas that 

contain the physical and biological 

features essential to the conservation of 

the species or unoccupied areas that are 

essential to the conservation of the 

species are not eroded. Critical habitat 

designation alone, however, does not 

require specific steps toward recovery. 

Once consultation under section 7 of 

the Act is triggered, the process may 

conclude informally when the Service 

concurs in writing that the proposed 

Federal action is not likely to adversely 

affect the listed species or its critical 

habitat. However, if the Service 

determines through informal 

consultation that adverse impacts are 

likely to occur, then formal consultation 

would be initiated. Formal consultation 

concludes with a biological opinion 

issued by the Service on whether the 

proposed Federal action is likely to 

jeopardize the continued existence of a 

listed species or result in destruction or 

adverse modification of critical habitat, 

with separate analyses being made 

under both the jeopardy and the adverse 

modification standards. For critical 

habitat, a biological opinion that 

concludes in a determination of no 

destruction or adverse modification may 

contain discretionary conservation 

recommendations to minimize adverse 

effects to primary constituent elements, 

but it would not contain any mandatory 

reasonable and prudent measures or 

terms and conditions. Mandatory 

measures and terms and conditions to 

implement such measures are only 

specified when the proposed action 

would result in the incidental take of a 

listed animal or species. Reasonable and 

prudent alternatives to the proposed 

Federal action would only be suggested 

when the biological opinion results in a 

jeopardy or adverse modification 

conclusion. 

We also note that for 30 years prior to 

the Ninth Circuit Court’s decision in 

Gifford Pinchot Task Force v. U.S. Fish 

and Wildlife Service, 378 F.3d 1059 (9th 

Cir 2004) (hereinafter Gifford Pinchot), 

the Service conflated the jeopardy 

standard with the standard for 

destruction or adverse modification of 

critical habitat when evaluating Federal 

actions that affect currently occupied 

critical habitat. The Court ruled that the 

two standards are distinct and that 

adverse modification evaluations 

require consideration of impacts on the 

recovery of species. Thus, under the 

Gifford Pinchot decision, critical habitat 

designations may provide greater 

benefits to the recovery of a species. 

However, we believe the conservation 

achieved through implementing HCPs 

or other habitat management plans is 

typically greater than would be 

achieved through multiple site-by-site, 

project-by-project, section 7 

consultations involving consideration of 

critical habitat. Management plans 

commit resources to implement longterm management and protection to 

particular habitat for at least one and 

possibly other listed or sensitive 

species. Section 7 consultations only 

commit Federal agencies to prevent 

adverse modification to critical habitat 

caused by the particular project, and 

they are not committed to provide 

conservation or long-term benefits to 

areas not affected by the proposed 

project. Thus, any HCP or management 

plan which considers enhancement or 

recovery as the management standard 

will often provide as much or more 

benefit than a consultation for critical 

habitat designation conducted under the 

standards required by the Ninth Circuit 

in the Gifford Pinchot decision. 

The information provided in this 

section applies to all the discussions 

below that discuss the benefits of 

inclusion and exclusion of critical 

habitat in that it provides the framework 

for the consultation process. 

Educational Benefits of Critical Habitat 

A benefit of including lands in critical 

habitat is that the designation of critical 

habitat serves to educate landowners, 

State and local governments, and the 

public regarding the potential 

conservation value of an area. This 

helps focus and promote conservation 

efforts by other parties by clearly 

delineating areas of high conservation 

value for Acanthomintha ilicifolia. In 

general, the educational benefit of a 

critical habitat designation always 

exists, although in some cases it may be 

redundant with other educational 

effects. For example, HCPs have 

significant public input and may largely 

duplicate the educational benefit of a 

critical habitat designation. This benefit 

is closely related to a second, more 

indirect benefit: that designation of 

critical habitat would inform State 

agencies and local governments about 

areas that could be conserved under 

State laws or local ordinances. 

However, we believe that there would 

be little additional informational benefit 

gained from the designation of critical 

habitat for the exclusions we are 

proposing in this rule because these 

areas are identified as having habitat 

containing the features essential to the 

conservation of the species. 

Consequently, we believe that the 

informational benefits are already 


cprice-sewell on PROD1PC66 with PROPOSALS2
Federal Register / Vol. 72, No. 49 / Wednesday, March 14, 2007 / Proposed Rules 11961 

provided even though these areas are 

not designated as critical habitat. 

Additionally, the purpose normally 

served by the designation, that of 

informing State agencies and local 

governments about areas that would 

benefit from protection and 

enhancement of habitat for 

Acanthomintha ilicifolia is already well 

established among State and local 

governments, and Federal agencies, in 

those areas that we are proposing to 

exclude from critical habitat in this rule 

on the basis of other existing habitat 

management protections. 

The information provided in this 

section applies to all the discussions 

below that discuss the benefits of 

inclusion and exclusion of critical 

habitat. 

Benefits of Excluding Lands With HCPs 

or Other Approved Management Plans 

From Critical Habitat 

The benefits of excluding lands with 

HCPs or other approved management 

plans from critical habitat designation 

include relieving landowners, 

communities, counties, and States of 

any additional regulatory burden that 

may occur through a critical habitat 

designation. Most HCPs and other 

conservation plans take many years to 

develop and, upon completion, are 

consistent with the recovery objectives 

for listed species that are covered within 

the plan area. Many conservation plans 

not only provide conservation benefits 

to federally listed species, but also to 

unlisted sensitive species. Imposing an 

additional layer of regulatory review as 

a result of the designation of critical 

habitat may undermine these 

conservation efforts and partnerships in 

many areas where HCPs or management 

plans exist or are being developed. 

Designation of critical habitat within the 

boundaries of management plans that 

provide conservation measures for a 

species could be viewed as a 

disincentive to those entities currently 

developing these plans or contemplating 

them in the future, because one of the 

incentives for undertaking conservation 

is greater ease of permitting where listed 

species are affected. The addition of a 

new regulatory requirement would 

remove a significant incentive for 

undertaking the time and expense of 

management planning. In fact, 

designating critical habitat in areas 

covered by a pending HCP or 

conservation plan could result in the 

loss of some conservation benefits to the 

species if participants abandon the 

planning process, in part because of the 

strength 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 

participation in plans targeting listed 

species’ conservation. 

A related benefit of excluding lands 

within an HCP or other management 

plan 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 HCP or other 

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 their habitats. By excluding 

these lands, we preserve our current 

partnerships and encourage additional 

conservation actions in the future. 

Furthermore, an HCP or Natural 

Communities Conservation Plan 

(NCCP)/HCP application must itself be 

consulted upon, even without the 

critical habitat designation. Such a 

consultation would review the effects of 

all activities covered by the HCP that 

might adversely impact the species 

under a jeopardy standard, including 

possibly significant habitat modification 

(see definition of ‘‘harm’’ at 50 CFR 

17.3). 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. 

The information provided in this 

section applies to all the discussions 

below that discuss the benefits of 

inclusion and exclusion of critical 

habitat. 

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

Act for Acanthomintha ilicifolia 

After consideration under section 

4(b)(2) of the Act, we are proposing to 

exclude the following areas from critical 

habitat for Acanthomintha ilicifolia: 

private lands covered by the San Diego 

Multiple Habitat Conservation Program 

in subunits 1A, 1B, and 1C and private 

lands covered by the San Diego Multiple 

Species Conservation Program in 

subunits 2A, 2B , 2C, 2D, 3A, 3B, 3C, 

3D, 3F, 4A, 4B, 4C, and 4D. We believe 

that: (1) The value of these lands for 

conservation has been addressed by 

existing protective actions, or (2) it is 

appropriate to exclude these lands 

pursuant to the ‘‘other relevant factor’’

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

We specifically solicit comment, 

however, on the inclusion or exclusion 

of such areas. A detailed analysis of our 

exclusion of these lands under section 

4(b)(2) of the Act is provided in the 

paragraphs that follow. 

Relationship of Critical Habitat to 

Habitat Conservation Plan Lands— 

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

Act 

We consider a current plan to provide 

adequate management or protection if it 

meets three criteria: (1) The plan is 

complete and provides the same or 

better level of protection from adverse 

modification or destruction than that 

provided through a consultation under 

section 7 of the Act; (2) there is a 

reasonable expectation that the 

conservation management strategies and 

actions will be implemented based on 

past practices, written guidance, or 

regulations; and (3) the plan provides 

conservation strategies and measures 

consistent with currently accepted 

principles of conservation biology. We 

believe that the following HCPs fulfill 

these criteria for Acanthomintha 

ilicifolia: the City of San Diego subarea 

plan, the County of San Diego subarea 

plan, the City of Poway subarea plan, 

the City of Chula Vista subarea plan 

under the San Diego MSCP, and the City 

of Carlsbad subarea plan under the San 

Diego MHCP. We are considering the 

exclusion of non-Federal lands covered 

by these plans that provide for the 

conservation of A. ilicifolia from the 

final designation of critical habitat 

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

We also consider HCP covered lands 

for exclusion under 4(b)(2) of the Act if 

the plans are approaching completion 

and, when completed, will meet the 

above criteria. We have proposed 

critical habitat in one subarea plan that 

has not yet been completed. The City of 

Encinitas completed a final draft 

subarea plan that was released for 

public review in 2001. This plan 

indicates that the City of Encinitas will 

complete the HCP process under the 

San Diego MHCP and implement the 

conservation measures outlined for 

Acanthomintha ilicifolia. However, it is 

our understanding that little progress 

has been made by the City of Encinitas 

to finalize their subarea plan since the 

2001 release of the draft plan. Therefore, 

we are seeking public comment on our 

proposal to exclude 92 ac (37 ha) of 

non-Federal lands in Subunit 1C 

covered by the City of Encinitas subarea 

plan of the San Diego MHCP pursuant 


cprice-sewell on PROD1PC66 with PROPOSALS2
11962 Federal Register / Vol. 72, No. 49 / Wednesday, March 14, 2007 / Proposed Rules 

to section 4(b)(2) of the Act (see Public 

Comments Solicited section above). 

Based on information received during 

the public comment period, the 

Secretary may determine that sufficient 

progress has not been made and that 

lands within the City of Encinitas’

subarea plan should not be excluded 

from the final designation of critical 

habitat. 

To aid in the public review of this 

proposed critical habitat, we are 

providing maps of the areas that we are 

proposing to exclude. Maps and GIS 

layers for areas proposed for exclusion 

are available from the Carlsbad Fish and 

Wildlife Office (see ADDRESSES) and on 

our website at http://carlsbad.fws.gov/ 

sdtm.htm. 

San Diego Multiple Habitat 

Conservation Program (MHCP) 

We are proposing to exclude from the 

final critical habitat designation 

approximately 172 ac (70 ha) of nonFederal lands within the City of 

Carlsbad subarea plan and the City of 

Encinitas subarea plans of the San Diego 

MHCP under section 4(b)(2) of the Act. 

The San Diego MHCP includes the 

following subareas: City of Carlsbad, 

City of Encinitas, City of Escondido, 

City of Oceanside, City of San Marcos, 

and City of Vista. We are proposing to 

exclude 7 ac (3 ha) in Subunit 1A and 

73 ac (29 ha) in Subunit 1B covered 

under the City of Carlsbad subarea plan, 

and 92 ac (37 ha) in Subunit 1C which 

will be covered under the City of 

Encinitas subarea plan. This exclusion 

pertains to all but 7ac (3 ha) of land 

proposed as critical habitat in Unit 1. 

Only the City of Carlsbad subarea plan 

is completed and legally operative; 

however the City of Encinitas completed 

a final draft subarea plan that was 

released for public review in 2001. Once 

in place, the City of San Marcos, City of 

Oceanside, City of Escondido, and City 

of Vista subarea plans will also provide 

for the conservation of A. ilicifolia; 

however, no critical habitat has been 

proposed within these cities. The City of 

Carlsbad and City of Encinitas subarea 

plans provide for special management 

and protection for the physical and 

biological features essential for the 

conservation of A. ilicifolia that exceed 

the level of regulatory control that 

would be afforded this species by the 

designation of critical habitat. We 

believe that the benefits of excluding 

proposed critical habitat covered by 

these HCPs from the critical habitat 

designation would outweigh the 

benefits of including them as critical 

habitat and that the exclusion under 

consideration would not result in the 

extinction of A. ilicifolia. 

The San Diego MHCP is a 

comprehensive, multi-jurisdictional, 

planning program designed to create, 

manage, and monitor an ecosystem 

preserve in northwestern San Diego 

County. The San Diego MHCP is also a 

regional subarea plan under the State of 

California’s Natural Communities 

Conservation Plan (NCCP) program and 

was developed in cooperation with 

California Department of Fish and Game 

(CDFG). The MHCP preserve system is 

intended to protect viable populations 

of native plant and animal species and 

their habitats in perpetuity, while 

accommodating continued economic 

development and quality of life for 

residents of northern San Diego County. 

The MHCP includes an approximately 

112,000-ac (45,324-ha) study area 

within the cities of Carlsbad, Encinitas, 

Escondido, San Marcos, Oceanside, 

Vista and Solana Beach. 

The 10(a)(1)(B) permit for the City of 

Carlsbad HMP was issued on November 

9, 2004. Acanthomintha ilicifolia is a 

conditionally covered species under the 

HMP. ‘‘Conditional’’ coverage means 

that the City of Carlsbad receives take 

authorization under the Act for this 

species as long as they comply with the 

conservation measures outlined in the 

HMP. Under the MHCP, the majority of 

the known populations fall within 

Focused Planning Areas (FPA) (core 

areas and linkages important for 

conservation of sensitive species) and 

will be conserved at levels of 95 to 100 

percent. Populations that fall outside of 

FPAs will be conserved at a minimum 

80 percent level based on the Narrow 

Endemic Plant policy. The Narrow 

Endemic Policy requires the 

conservation of new populations of 

narrow endemic species (80 percent 

outside of FPAs) and mitigation for 

unavoidable impacts as well as 

management practices designed to 

achieve no net loss of narrow endemic 

populations. In addition, cities cannot 

permit more than 5 percent gross 

cumulative loss of narrow endemic 

populations or occupied acreage within 

the Focused Planning Areas and no 

more than 20 percent cumulative loss of 

narrow endemic locations, population 

numbers, or occupied acreage outside of 

Focused Planning Areas (AMEC Earth 

and Environmental, Inc. 2003). 

According to the MHCP, 91 percent of 

the major populations and critical 

locations of this species (as identified in 

the MHCP) in the study area will be 

conserved under the FPA design. In 

addition to conserved point localities, 

an estimated 3,403 acres of potentially 

suitable habitat will be conserved as a 

result of the existing preserve design 

and preserve policies. 

The subarea plan for the City of 

Encinitas follows the same framework 

under the MHCP, allowing for similar 

conservation and management of known 

A. ilicifolia populations. Areas that 

contain features essential to the 

conservation of the species that fall 

within the boundaries of both the City 

of Carlsbad and the City of Encinitas 

subarea plans under the MHCP will be 

incorporated into the preserve areas, 

and provisions to manage the 

populations within the preserve areas 

will provide for the long-term 

conservation of the species. 

Benefits of Exclusion Outweigh the 

Benefits of Inclusion 

We expect the approved City of 

Carlsbad subarea plan and the City of 

Encinitas subarea plan, once approved, 

to provide substantial protection and 

management of the PCE essential to the 

conservation of Acanthomintha 

ilicifolia on lands in Subunit 1A (7 ac 

(3 ha)), Subunit 1B (73 ac (29 ha)), and 

Subunit 1C (92 ac (37 ha)). We expect 

the subarea plans to provide active 

management for A. ilicifolia on nonFederal lands in contrast to designation 

of critical habitat, which would only 

preclude their destruction or adverse 

modification. Moreover, the educational 

benefits that would result from critical 

habitat designation, including informing 

the public of areas that are necessary for 

the long-term conservation of the 

species, are already in place both as a 

result of material provided on our 

website and through public notice-andcomment procedures required to 

establish the MHCP and associated 

subarea plans. 

In contrast to the lack of an 

appreciable benefit of including these 

lands as critical habitat, the exclusion of 

these lands from critical habitat will 

help preserve the partnerships that we 

have developed with the local 

jurisdictions and project proponents in 

the development of the MHCP and 

associated subarea plans. As discussed 

above, many landowners perceive 

critical habitat as an unfair and 

unnecessary regulatory burden given the 

expense and time involved in 

developing and implementing complex 

regional HCPs, such as the MHCP. For 

these reasons, we believe that 

designating critical habitat has little 

benefit in areas covered by subarea 

plans of the MHCP, and such minor 

benefit is outweighed by the benefits of 

maintaining partnerships with local 

jurisdictions and private landowners 

with lands covered by the MHCP. 


cprice-sewell on PROD1PC66 with PROPOSALS2
Federal Register / Vol. 72, No. 49 / Wednesday, March 14, 2007 / Proposed Rules 11963 

We have reviewed and evaluated the 

benefits of inclusion and the benefits of 

exclusion of lands as critical habitat for 

Acanthomintha ilicifolia. Based on this 

evaluation, we find that the benefits of 

excluding lands in areas covered by the 

City of Carlsbad and City of Encinitas 

subarea plans of the MHCP outweigh 

the benefits of including those lands as 

critical habitat for A. ilicifolia. 

Exclusion Will Not Result in Extinction 

of the Species 

Exclusion of these 172 ac (70 ha) of 

non-Federal lands from the final 

designation of critical habitat would not 

result in the extinction of 

Acanthomintha ilicifolia because these 

lands will be permanently conserved 

and managed for the benefit of this 

species pursuant to the MHCP subarea 

plans. The jeopardy standard of section 

7 and routine implementation of habitat 

protection through the section 7 process 

also provide assurances that the species 

will not go extinct. The protections 

afforded to A. ilicifolia under the 

jeopardy standard will remain in place 

for the areas proposed for exclusion 

from critical habitat. 

San Diego Multiple Species 

Conservation Program (MSCP) 

We are proposing to exclude from the 

final critical habitat designation 

approximately 1,130 ac (457 ha) of nonFederal lands within the City of San 

Diego subarea plan and the County of 

San Diego subarea plan of the San Diego 

MSCP under section 4(b)(2) of the Act. 

We propose to exclude 63 ac (25 ha) in 

Subunit 2A and 52 ac (22 ha) in Subunit 

2B covered by the City of San Diego 

subarea plan, and 306 ac (124 ha) in 

Subunit 2C, 77 ac (31 ha) in Subunit 2D, 

33 ac (13 ha) in Subunit 3A, 156 ac (63 

ha) in Subunit 3B, 38 ac (15 ha) in 

Subunit 3C, 50 ac (20 ha) in Subunit 3D, 

7 ac (3 ha) in Subunit 3F, 18 ac (7 ac) 

in Subunit 4A, 220 ac (89 ha) in Subunit 

4B, 27 ac (11 ha) in Subunit 4C, and 84 

ac (34 ha) in Subunit 4D covered by the 

County of San Diego subarea plan of the 

San Diego MSCP. Acanthomintha 

ilicifolia is a covered species under 

these two approved and legally 

operative subarea plans. The City of 

Poway and the City of Chula Vista have 

subarea plans that also provide for the 

conservation of A. ilicifolia; however, 

no critical habitat has been proposed 

within the City of Poway or the City of 

Chula Vista. These HCPs provide 

special management and protection for 

the physical and biological features 

essential for the conservation of A. 

ilicifolia that exceed the level of 

regulatory control that would be 

afforded this species by the designation 

of critical habitat. We believe that the 

benefits of excluding proposed critical 

habitat covered by these HCPs from the 

critical habitat designation would 

outweigh the benefits of including them 

as critical habitat and that the exclusion 

under consideration would not result in 

the extinction of A. ilicifolia. 

In southwestern San Diego County, 

the MSCP effort encompasses more than 

582,000 ac (236,000 ha) and anticipates 

the participation of 12 jurisdictions. 

Under the broad umbrella of the MSCP, 

each of the 12 participating jurisdictions 

prepares a subarea plan that implements 

the goals of the MSCP within that 

particular jurisdiction. Four of the 12 

jurisdictions cover lands that support 

Acanthomintha ilicifolia. All four of 

these jurisdictions, the City of San 

Diego, the City of Chula Vista, the 

County of San Diego, and the City of 

Poway, have approved subarea plans. 

We conduct a consultation on each 

subarea plan and associated permit 

under section 7 of the Act to ensure they 

are not likely to result in jeopardy or 

adversely modify or destroy the 

designated critical habitat of any 

covered species. We also review the 

plans under Section 10 of the Act to 

ensure they meet the criteria for 

issuance of an incidental take permit 

and are consistent with the terms and 

goals of the MSCP. We completed these 

analyses for the City of San Diego, the 

City of Chula Vista, the County of San 

Diego, and the City of Poway subarea 

plans prior to issuing incidental take 

permits to the jurisdictions. 

The regional MSCP is also a regional 

subarea plan under the State of 

California’s Natural Communities 

Conservation Plan (NCCP) program and 

was developed in cooperation with 

California Department of Fish and Game 

(CDFG). Over the 50-year term of the 

City and County permits, the MSCP 

provides for the establishment of 

approximately 171,000 ac (69,573 ha) of 

preserve lands within the Multi-Habitat 

Planning Area (MHPA) (City of San 

Diego) and Pre-Approved Mitigation 

Areas (PAMA) (County of San Diego) to 

benefit the 85 federally listed and 

sensitive species, including 

Acanthomintha ilicifolia, covered under 

the plan. Private lands within the 

MHPA and PAMA lands are subject to 

special restrictions on development and, 

as they are committed to the preserve, 

must be legally protected and 

permanently managed to conserve the 

covered species. Public lands owned by 

the City and County and by the State of 

California and Federal government that 

are identified for conservation under the 

MSCP must also be protected and 

permanently managed to protect the 

covered species. The MSCP requires the 

City and County to develop broad 

framework and site-specific 

management plans, subject to the review 

and approval of the Service and CDFG, 

to guide the management of all preserve 

lands under City and County control. 

The plans incorporate requirements to 

monitor and adaptively manage A. 

ilicifolia habitats over time. Under the 

MSCP, the State and Federal 

governments have also committed to 

provide similar management for their 

preserve lands. 

As discussed above, each take 

authorization holder must prepare a 

framework management plan. The 

framework management plan provides 

general direction for all preserve 

management issues within the subarea 

plan’s boundaries. Area-specific 

management directives are developed 

for managing lands that are conserved as 

part of the reserves. The framework and 

area-specific management plans are 

comprehensive and address a broad 

range of management needs at the 

preserve and species levels. These plans 

include the following: (1) Fire 

management; (2) public access control; 

(3) fencing and gates; (4) ranger patrol; 

(5) trail maintenance; (6) visitor/ 

interpretive and volunteer services; (7) 

hydrological management; (8) signage 

and lighting; (9) trash and litter removal; 

(10) access road maintenance; (11) 

enforcement of property and/or 

homeowner requirements; (12) removal 

of invasive species; (13) nonnative 

predator control; (14) species 

monitoring; (15) habitat restoration; (16) 

management for diverse age classes; (17) 

use of herbicides and rodenticides; (18) 

biological surveys; (19) research; and 

(20) species management conditions 

(Final MSCP Plan 1998). These 

management measures benefit 

Acanthomintha ilicifolia and reduce the 

threats to this species. The MSCP also 

provides for a biological monitoring 

program for A. ilicifolia (Final MSCP 

Plan 1998). The City of San Diego 

monitors A. ilicifolia on an annual basis 

(City of San Diego 2000; 2001; 2003; 

2004; and 2005). Moreover, the rare 

plant monitoring under the MSCP is 

being evaluated and updated with the 

assistance of the U.S. Geological Survey 

Biological Research Division and a 

three-member, independent, scientific 

advisory group. 

In addition to the restrictions on 

development and conservation 

obligations that apply within the 

Multiple Habitat Planning Area (MHPA) 

and Pre-Approved Mitigation Area 

(PAMA), the MSCP incorporates 

processes to protect sensitive species of 

limited distribution, including 


cprice-sewell on PROD1PC66 with PROPOSALS2
11964 Federal Register / Vol. 72, No. 49 / Wednesday, March 14, 2007 / Proposed Rules 

Acanthomintha ilicifolia, within the 

plan area. Under the City of San Diego’s 

subarea plan, impacts to narrow 

endemic species inside the MHPA will 

be avoided and outside the MHPA will 

be protected as appropriate by (1) 

avoidance, (2) management, (3) 

enhancement, and/or (4) transplantation 

to areas identified for preservation. 

Under the County of San Diego’s 

subarea plan, narrow endemic plants, 

including A. ilicifolia, would be 

conserved under their Biological 

Mitigation Ordinance using a process 

that (1) requires avoidance to the 

maximum extent feasible, (2) allows for 

a maximum 20 percent encroachment 

into a population if total avoidance is 

not feasible, and (3) requires mitigation 

at the 1:1 to 3:1 (in kind) for impacts if 

avoidance and minimization of impacts 

would result in no reasonable use of the 

property. Thus, these processes to 

protect narrow endemic plants, 

including A. ilicifolia, whether located 

on lands targeted for preserve status 

within the MHPA and PAMA or located 

outside of those areas, ensure these 

limited distribution species are 

protected wherever they occur. 

Considered as a whole, the protection 

and management of A. ilicifolia 

provided under the City and County 

subarea plans will ensure the permanent 

conservation of this species and its 

habitat within the areas covered by the 

plans. 

We therefore propose to exclude from 

the final critical habitat designation all 

of Unit 2 and Unit 4 and the nonFederal portion of Unit 3 under section 

4(b)(2) of the Act because these lands 

are covered by the City of San Diego and 

the County of San Diego subarea plans. 

Populations of Acanthomintha ilicifolia 

that occur within these subarea plan 

areas will be conserved and will be 

managed and monitored pursuant to the 

MSCP. The framework and area-specific 

management plans will provide 

management and monitoring of A. 

ilicifolia. 

Benefits of Exclusion Outweigh the 

Benefits of Inclusion 

We expect the City of San Diego and 

the County of San Diego subarea plans 

to provide substantial protection and 

management of habitat that contains 

features essential to the conservation of 

Acanthomintha ilicifolia in areas 

covered by these plans. We expect these 

subarea plans to provide active 

management for A. ilicifolia on nonFederal lands in contrast to designation 

of critical habitat, which would only 

preclude their destruction or adverse 

modification. Moreover, the educational 

benefits that would result from critical 

habitat designation, including informing 

the public of areas that are necessary for 

the long-term conservation of the 

subspecies, are already in place both as 

a result of material provided on our Web 

site and through public notice-andcomment procedures required to 

establish the MSCP and specific subarea 

plans. 

In contrast to the lack of an 

appreciable benefit of including these 

lands as critical habitat, the exclusion of 

these lands from critical habitat will 

help preserve the partnerships that we 

have developed with the local 

jurisdictions and project proponents in 

the development of the MSCP. As 

discussed above, many landowners 

perceive critical habitat as an unfair and 

unnecessary regulatory burden given the 

expense and time involved in 

developing and implementing complex 

regional HCPs, such as the MSCP. For 

these reasons, we believe that 

designating critical habitat has little 

benefit in areas covered by the MSCP 

subarea plans, and such minor benefit is 

outweighed by the benefits of 

maintaining partnerships with local 

jurisdictions and private landowners 

with lands covered by the MSCP. 

We have reviewed and evaluated the 

benefits of inclusion and the benefits of 

exclusion of lands as critical habitat for 

Acanthomintha ilicifolia. Based on this 

evaluation, we find that the benefits of 

excluding lands in the planning area for 

the City of San Diego and the County of 

San Diego subarea plans outweigh the 

benefits of including those lands as 

critical habitat for A. ilicifolia. 

Exclusion Will Not Result in Extinction 

of the Species 

Exclusion of these 1,130 ac (457 ha) 

of non-Federal lands from the final 

designation of critical habitat will not 

result in the extinction of 

Acanthomintha ilicifolia because these 

lands, determined to contain features 

essential to the conservation of the 

species, will be permanently conserved 

and managed for the benefit of this 

species pursuant to the approved MSCP 

subarea plans. The jeopardy standard of 

section 7 and routine implementation of 

habitat protection through the section 7 

process also provide assurances that the 

species will not go extinct. The 

protections afforded to A. ilicifolia 

under the jeopardy standard will remain 

in place for the areas proposed for 

exclusion from critical habitat. 

Economic Analysis 

An analysis of the economic impacts 

of proposing critical habitat for 

Acanthomintha ilicifolia is being 

prepared. We will announce the 

availability of the draft economic 

analysis as soon as it is completed, at 

which time we will seek public review 

and comment. At that time, copies of 

the draft economic analysis will be 

available for downloading from the 

Internet at http://www.fws.gov/carlsbad/ 

or by contacting the Carlsbad Fish and 

Wildlife Office directly (see ADDRESSES

section). Based on public comments, the 

proposed designation itself, and the 

information in the full economic 

analysis, areas in addition to those 

proposed for exclusion in this proposed 

rule may be excluded from final critical 

habitat by the Secretary under the 

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

This is provided for in the Act and in 

our implementing regulations at 50 CFR 

424.19. 

Peer Review 

In accordance with our joint policy 

published in the Federal Register on 

July 1, 1994 (59 FR 34270), we will seek 

the expert opinions of at least three 

appropriate and independent specialists 

regarding this proposed rule. The 

purpose of such review is to ensure that 

our critical habitat designation is based 

on scientifically sound data, 

assumptions, and analyses. We will 

send these peer reviewers copies of this 

proposed rule immediately following 

publication in the Federal Register. We 

will invite these peer reviewers to 

comment, during the public comment 

period, on the specific assumptions and 

conclusions regarding the proposed 

designation of critical habitat. 

We will consider all comments and 

information received during the 

comment period on this proposed rule 

during preparation of a final 

rulemaking. Accordingly, the final 

decision may differ from this proposal. 

Public Hearings 

The Act provides for one or more 

public hearings on this proposal, if 

requested. Requests for public hearings 

must be made in writing at least 15 days 

prior to the close of the public comment 

period (see DATES section). 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 


cprice-sewell on PROD1PC66 with PROPOSALS2
Federal Register / Vol. 72, No. 49 / Wednesday, March 14, 2007 / Proposed Rules 11965 

in the proposed rule clearly stated? (2) 

Does the proposed rule contain 

technical jargon that interferes with the 

clarity? (3) Does the format of the 

proposed rule (grouping and order of 

the sections, use of headings, 

paragraphing, and so forth) aid or 

reduce its clarity? (4) Is the description 

of the notice in the SUPPLEMENTARY

INFORMATION section of the preamble 

helpful in understanding the proposed 

rule? (5) What else could we do to make 

this proposed rule easier to understand? 

Send a copy of any comments on how 

we could make this proposed rule easier 

to understand to: Office of Regulatory 

Affairs, Department of the Interior, 

Room 7229, 1849 C Street, NW., 

Washington, DC 20240. You may e-mail 

your comments to this address:

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 

subspecies. As such, we believe that the 

evaluation of the inclusion or exclusion 

of particular areas, or combination 

thereof, in a designation constitutes our 

regulatory alternative analysis. 

The availability of the draft economic 

analysis will be announced in the 

Federal Register and in local 

newspapers so that it is available for 

public review and comments. The draft 

economic analysis can be obtained from 

the Internet Web site at http:// 

www.fws.gov/carlsbad/ or by contacting 

the Carlsbad Fish and Wildlife Office 

directly (see ADDRESSES section). 

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

et seq.) 

Under the Regulatory Flexibility Act 

(5 U.S.C. 601 et seq., as amended by the 

Small Business Regulatory Enforcement 

Fairness Act (SBREFA) of 1996), 

whenever an agency is required to 

publish a notice of rulemaking for any 

proposed or final rule, it must prepare 

and make available for public comment 

a regulatory flexibility analysis that 

describes the effects of the rule on small 

entities (i.e., small businesses, small 

organizations, and small government 

jurisdictions). However, no regulatory 

flexibility analysis is required if the 

head of the agency certifies the rule will 

not have a significant economic impact 

on a substantial number of small 

entities. The SBREFA amended the 

Regulatory Flexibility Act (RFA) to 

require Federal agencies to provide a 

statement of the factual basis for 

certifying that the rule will not have a 

significant economic impact on a 

substantial number of small entities. 

At this time, the Service lacks the 

available economic information 

necessary to provide an adequate factual 

basis for the required RFA finding. 

Therefore, the RFA finding is deferred 

until completion of the draft economic 

analysis prepared under section 4(b)(2) 

of the Act and Executive Order 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 

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; Actions 

Concerning Regulations That 

Significantly Affect Energy Supply, 

Distribution, or Use) 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. While this 

proposed rule to designate critical 

habitat for Acanthomintha ilicifolia is a 

significant regulatory action under 

Executive Order 12866, in that it may 

raise novel legal and policy issues, 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 


cprice-sewell on PROD1PC66 with PROPOSALS2
11966 Federal Register / Vol. 72, No. 49 / Wednesday, March 14, 2007 / Proposed Rules 

more is provided annually to State, 

local, and Tribal governments under 

entitlement authority,’’ if the provision 

would ‘‘increase the stringency of 

conditions of assistance’’ or ‘‘place caps 

upon, or otherwise decrease, the Federal 

Government’s responsibility to provide 

funding,’’ and the State, local, or Tribal 

governments ‘‘lack authority’’ to adjust 

accordingly. At the time of enactment, 

these entitlement programs were: 

Medicaid; AFDC work programs; Child 

Nutrition; Food Stamps; Social Services 

Block Grants; Vocational Rehabilitation 

State Grants; Foster Care, Adoption 

Assistance, and Independent Living; 

Family Support Welfare Services; and 

Child Support Enforcement. ‘‘Federal 

private sector mandate’’ includes a 

regulation that ‘‘would impose an 

enforceable duty upon the private 

sector, except (i) a condition of Federal 

assistance or (ii) a duty arising from 

participation in a voluntary Federal 

program.’’

The designation of critical habitat 

does not impose a legally binding duty 

on non-Federal Government entities or 

private parties. Under the Act, the only 

regulatory effect is that Federal agencies 

must ensure that their actions do not 

destroy or adversely modify critical 

habitat under section 7. While nonFederal 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) We do not believe that this rule 

will significantly or uniquely affect 

small governments because 91 percent 

of the lands being proposed for final 

designation are managed by Federal 

agencies and do not fit the definition of 

‘‘small governmental jurisdiction.’’ 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. 

Takings 

In accordance with Executive Order 

12630 (‘‘Government Actions and 

Interference with Constitutionally 

Protected Private Property Rights’’), we 

have analyzed the potential takings 

implications of designating critical 

habitat for Acanthomintha ilicifolia in a 

takings implications assessment. The 

takings implications assessment 

concludes that this designation of 

critical habitat for the A. ilicifolia does 

not pose significant takings 

implications. 

Federalism 

In accordance with Executive Order 

13132 (Federalism), the rule does not 

have significant Federalism effects. A 

Federalism assessment is not required. 

In keeping with Department of the 

Interior and Department of Commerce 

policy, we requested information from, 

and coordinated development of, this 

proposed critical habitat designation 

with appropriate State resource agencies 

in California. The designation of critical 

habitat in areas currently occupied by 

Acanthomintha ilicifolia imposes no 

additional restrictions to those currently 

in place and, therefore, has little 

incremental impact on State and local 

governments and their activities. The 

designation may have some benefit to 

these governments in that the areas that 

contain the features essential to the 

conservation of the species are more 

clearly defined, and the primary 

constituent elements of the habitat 

necessary to the conservation of the 

species are specifically identified. While 

making this definition and 

identification does not alter where and 

what federally sponsored activities may 

occur, it may assist these local 

governments in long-range planning 

(rather than waiting for case-by-case 

section 7 consultations to occur). 

Civil Justice Reform 

In accordance with Executive Order 

12988, the Office of the Solicitor has 

determined that the rule does not 

unduly burden the judicial system and 

meets the requirements of sections 3(a) 

and 3(b)(2) of the Order. We have 

proposed designating critical habitat in 

accordance with the provisions of the 

Act. This proposed rule uses standard 

property descriptions and identifies the 

primary constituent elements within the 

designated areas to assist the public in 

understanding the habitat needs of 

Acanthomintha ilicifolia. 

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 

jurisdiction of the Tenth Federal Circuit 

Court, we do not need to prepare 

environmental analyses as defined by 

the NEPA in connection with 

designating critical habitat under the 

Endangered Species Act of 1973, as 

amended. 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 

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 that were occupied at the time of 

listing that contain features essential for 

the conservation of Acanthomintha 

ilicifolia and no Tribal lands essential 

for the conservation of A. ilicifolia. 

Therefore, critical habitat for A. ilicifolia 

has not been proposed on Tribal lands.
