RIN 1018–AU78 

Endangered and Threatened Wildlife 

and Plants; Designation of Critical 

Habitat for the Guajo ́n 

(Eleutherodactylus cooki) 

AGENCY: Fish and Wildlife Service, 

Interior. 

ACTION: Proposed rule. 

SUMMARY: We, the U.S. Fish and 

Wildlife Service (Service), propose to 

designate critical habitat for the 

threatened guajo ́n (Eleutherodactylus 

cooki), a frog endemic to Puerto Rico, 

under the Endangered Species Act of 

1973, as amended (Act). In total, 

approximately 217.2 acres (ac) (88 

hectares (ha)) fall within the boundaries 

of the proposed critical habitat 

designation. The proposed critical 

habitat is located in the municipalities 

of Humacao, Las Piedras, Maunabo, 

Patillas, and Yabucoa, Puerto Rico. 

DATES: We will accept comments from 

all interested parties until December 4, 

2006. We must receive requests for 

public hearings, in writing, at the 

address shown in the ADDRESSES section 

by November 20, 2006.

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 for the guajo ́n as provided by 

section 4 of the Endangered Species Act 

of 1973, as amended (Act) (16 U.S.C. 

1531 et. seq.), including whether it is 

prudent to designate critical habitat; 

(2) Specific information on the 

amount and distribution of guajo ́n 

habitat, and what areas should be 

included in the designation that were 

occupied at the time of listing that 

contain the features that are 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 and why; 

(3) Land use designations and current 

or planned activities in the subject areas 

and their possible impacts on proposed 

critical habitat; 

(4) Any foreseeable economic, 

national security, or other potential 

impacts resulting from the proposed 

designation and, in particular, any 

impacts on small entities; 

(5) Whether the benefit of exclusion of 

any particular area outweigh the 

benefits of inclusion under section 

4(b)(2) of the Act; and 

(6) Whether our approach to 

designating critical habitat could be 

improved or modified in any way to 

provide for greater public participation 

and understanding, or to assist us in 

accommodating public concerns and 

comments. 

If you wish to comment, you may 

submit your comments and materials 

concerning this proposal by any one of 

several methods (see ADDRESSES

section). Please submit Internet 

comments to jorge_saliva@fws.gov in

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/or 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 

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 ESA section 4(b)(2), 

there are significant limitations on the 

regulatory effect of designation under 

ESA section 7(a)(2). 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 


pwalker on PRODPC60 with PROPOSALS3
Federal Register / Vol. 71, No. 193 / Thursday, October 5, 2006 / Proposed Rules 58955 

of destruction or adverse modification 

of that habitat, but it does not require 

specific actions to restore or improve 

habitat. 

Currently, only 470 species or 37 

percent of the 1,264 listed species in the 

United States under the jurisdiction of 

the Service, have designated critical 

habitat. We address the habitat needs of 

all 1,264 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 evaluated 

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). 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 this final designation. 

Rather, it relies on the guidance issued 

by the Director in response to the 

Gifford Pinchot decision (see ‘‘Adverse 

Modification Standard’’ discussion 

below). 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 time frame 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 

(NOIs) 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 

In this proposed rule, we intend to 

discuss only those topics directly 

relevant to the designation of critical 

habitat. For more information on the 

guajo ́n (which is also known as the 

Puerto Rican demon), refer to the final 

listing rule published in the Federal 

Register on June 11, 1997 (62 FR 31757). 

The guajo ́n is a petricolous (i.e., 

inhabiting rocks) frog species endemic 

to the southeastern part of Puerto Rico. 

This species is one of 16 species of the 

genus Eleutherodactylus, commonly 

known as ‘‘coquı ́es,’’ that inhabit the 

island. It is the second largest species of 

Eleutherodactylus in Puerto Rico. The 

guajo ́n has solid brown dorsal 

coloration, white-rimmed eyes, and 

large, truncate (i.e., partially cut) disks 

on its feet (Rivero 1998, p. 13; Joglar 

1986, p. 386). The species exhibits 

sexual dimorphism (separate female and 

male forms) in size, vocalization, and 

coloration (Burrowes 2000, pp. 376, 380; 

Burrowes 1997, p. 26). Females are 

larger than males. The mean size (snoutvent length) for females is 2.01 inches 

(in) (50.94 millimeters (mm)) and for 

males is 1.71 in (43.43 mm). The ventral 

coloration of females is uniformly 

white, while males are yellow extending 

from the vocal sac to the abdomen and 

flanks. Males call for mates by 

producing 3 to 7 similar notes (Drewry 

and Rand 1983, p. 944). Females 

produce only a short, acute call when 

distressed (Burrowes 2000, p. 383). 

Juveniles are brown in color with a 

dorsal pattern of dark brown inverted 

parentheses (Joglar et al. 1996, p. 254; 

Joglar 1998, p. 68). 

The guajo ́n was thought to be limited 

in distribution by the presence of caves, 

grottoes, and rock formations (Rivero 

1998, p. 13; Joglar 1998, p. 62). At the 

time of listing in 1997 (62 FR 31757), 

the guajo ́n was known to be found in 

the Cuchilla de Panduras mountain 

range (municipalities of Maunabo, San 

Lorenzo, and Yabucoa), and in the 

municipalities of Patillas, Humacao, and 

Las Piedras (Moreno 1991, p. 9; Joglar 

1992, p. 40; Joglar et al. 1996, p. 253; F. 

Bird, pers. comm. 1995; C. Ruiz-Lebro ́n, 

pers. comm. 2006). For many years, the 

guajo ́n was believed to be a highly 

localized species that occurred 

exclusively inside caves (Joglar 1998, 

pp. 62, 71; Joglar et al. 1996, p. 256; 

Burrowes 1997, p. 6; Burrowes 2000, p. 

376), but additional habitat studies of 

this species (Vega-Castillo 2000, pp. 36– 

37, 40) have shown that the guajo ́n also 


pwalker on PRODPC60 with PROPOSALS3
58956 Federal Register / Vol. 71, No. 193 / Thursday, October 5, 2006 / Proposed Rules 

lives in rocky streams. Since listing, we 

have discovered additional populations 

in three areas: (1) In Tejas Ward (Las 

Piedras) in an area bounded by Road 

PR–905 to the east, Road PR–908 to the 

west, Road PR–9921 to the north, and 

Road PR–9904 to the south; (2) in 

Guayabota Ward (Yabucoa) in an area 

south of Road PR–900 and north of the 

Maunabo boundary; and (3) within 

Guayabota Ward (Yabucoa), in an area 

that crosses Road PR–900 north of the 

Maunabo boundary, and is about 3,000 

ft (900 m) west of proposed critical 

habitat Unit 11. 

The guajo ́n is found at low and 

intermediate elevations where it 

inhabits caves formed by large boulders 

of granite rock, and associated streams 

with patches of rock without cave 

systems (Burrowes and Joglar 1999, p. 

706; Vega-Castillo 2000, p. 35; C. RuizLebro ́n, pers. comm., 2006). 

Structurally, the caves are complex, 

having several chambers of irregular 

shape and size, and may be at different 

depths between the surface of the 

ground and stream (Burrowes 2000, p. 

376). The ecological conditions of the 

caves are relatively uniform; mean 

temperature and relative humidity are 

the same at any given month of the year, 

and they do not have thermal 

stratification (i.e., no marked 

temperature differences between the 

floor and ceiling of the cave) (Rogowitz 

et al. 1999, p. 179; Rogowitz et al. 2001, 

pp. 542, 545; Burrowes 1997, p. 74). 

Like most of the Eleutherodactylus, the 

guajo ́n has direct development of eggs, 

which are laid on humid boulders 

within grottoes and on cracks, 

depressions, or flat vertical surfaces 

(Joglar et al. 1996, p. 253; Burrowes 

1997, pp. 21–22). The preference for this 

type of microhabitat probably reduces 

evaporative water loss and egg 

predation (Joglar 1998, pp. 64, 68). 

Vega-Castillo (2000, pp. 36, 40) 

reported that, in streams, the guajo ́n has 

been found only in patches of rock in 

the streambed. The streams can be 

perennial or they can be ephemeral, 

formed during heavy rain; the streams 

are also surrounded by secondary forest. 

Rocks in the streambed form crevices 

and grottoes. Streams provide a wide 

variety of retreat sites for the species, 

such as vegetation-covered rocks (e.g., 

rocks covered with moss, ferns, and 

liverworts) that help conserve humidity. 

In rocky stream habitat, the frogs exit 

their retreat site at dusk to forage 

actively over rocks and vegetation. In 

both types of habitat, the species 

exhibits site fidelity and homing 

behavior. Reproductive activity is 

correlated with precipitation and air 

temperature (Rogowitz et al. 2001, pp. 

543–546; Joglar et al. 1996, p. 254), and 

males defend and guard egg clutches 

(Joglar et al. 1996, p. 255; Burrowes 

1997, p. 35). 

The guajo ́n was listed as threatened 

under the Act primarily due to its 

highly restricted geographical 

distribution and habitat requirements 

(Joglar 1998, p. 73). The habitat of this 

species is naturally fragmented and the 

majority of the known populations are 

on private land in southeastern Puerto 

Rico, where the increased levels of land 

development threaten to further reduce 

and fragment the species habitat, 

distribution, and survival (Joglar 1998, 

p. 73). Being a habitat specialist, the 

guajo ́n is adapted to particular 

environmental conditions, and abrupt 

changes in these conditions could result 

in population declines or extirpation. 

Road and urban development can 

cause earth movement and modification 

of vegetation and streams, resulting in 

habitat fragmentation that may interrupt 

the connection between subpopulations, 

affecting the genetic variability and 

population numbers of the guajo ́n 

(Burrowes 1997, p. 71; Joglar 1998, p. 

73). Amphibian populations unable to 

disperse because of barriers may 

experience genetic isolation resulting in 

reduced heterozygosity (i.e., potential 

reduction in genetic variability and 

evolutionary fitness). Fragmenting 

habitat through human activity such as 

roads makes populations less resilient to 

natural population declines (Pechman et 

al. 1991, p. 895). 

Deforestation near streams can result 

in erosion and increase flash flooding. 

Runoff water from slopes during flash 

flooding may disturb the habitat of the 

guajo ́n, and high levels of sediment 

introduced into streams can fill spaces 

between rocks and decrease the 

availability of retreat sites among the 

boulders. Another potential effect of 

flash flooding is the flushing and 

drowning of adults, as well as the 

destruction of nests. 

The use of pesticides, herbicides, and 

fertilizers in agricultural fields could 

have detrimental effects on survival of 

the guajo ́n from runoff into waterways 

adjacent to guajo ́n habitat. Many studies 

have documented negative impacts of 

agrochemicals on frogs; impacts include 

deformities, abnormal immune system 

functions, diseases, injury and death 

(Cooke 1981, pp. 123, 125, 127, 130, 

131; Reeder et al. 1998, p. 264). Also, 

any stream modification (e.g., 

embankment, channelization) or 

development (e.g., tourist, urban) within 

the watershed where the guajo ́n exists 

could result in an increase of chemicalladen sediments and alteration of the 

streams’ quality. 

Recreational use of streams may 

degrade the habitat quality for the 

guajo ́n. People that live adjacent to 

guajo ́n habitat may collect crabs and 

shrimp by pouring chemicals into the 

water (e.g., chlorine). Aquatic species 

exit their retreats to the surface for 

breathing. These chemicals may directly 

affect water and habitat quality for the 

guajo ́n. A decrease in water and habitat 

quality may have a serious impact on 

this species and other amphibians that 

inhabit streams. Recreational use of 

streams may introduce trash and waste 

to the water flow impacting the water 

quality and habitat (Joglar 1993, pp. 27, 

33; Joglar et al. 1996, p. 258; Rivero 

1991, p. 55). For example, caves in the 

Cuchilla de Panduras mountain range 

are used as garbage dumps (Joglar 1998, 

p. 75), attracting potential predators and 

diseases for the guajo ́n. 

Burrowes (1997, pp. 60–64) and 

Burrowes and Joglar (1999, pp. 709–710) 

assessed the genetic variation within 

and among populations of the guajo ́n in 

separate cave systems within the 

historic geographic range of the species 

and found a high degree of genetic 

variation and lack of population 

differentiation in the species. These 

studies also documented that genetic 

flow among populations of the guajo ́n is 

necessary to maintain the high genetic 

variability observed in the species. This 

genetic variability depends on 

interconnection between caves, and the 

availability of clean subterranean 

waterways as indirect dispersal routes 

necessary for out-crossing (Burrowes 

1997, p. 73; Burrowes and Joglar 2000, 

p. 709). These studies also suggested 

that the guajo ́n is perfectly adapted to 

the existing environmental conditions 

in the caves. Thus, habitat conditions, 

e.g., clean waterways between the 

guajonales (the caves and grottoes where 

the guajo ́n lives), are important to 

maintain a high degree of genetic 

variation among the guajo ́n populations. 

Previous Federal Actions 

The guajo ́n was listed as threatened 

under the Act on June 11, 1997 (62 FR 

31757), due to its restricted distribution, 

specialized habitat utilization, and 

threats to its habitat. The Service 

determined that designation of critical 

habitat was not prudent at the time of 

listing because of increased risks of 

vandalism and illegal collection should 

the exact location of individuals be 

made public. On June 10, 2003, the 

Center for Biological Diversity filed a 

lawsuit against the Department of the 

Interior and the Service, alleging, among 

other things, failure to designate critical 

habitat for the guajo ́n. In a settlement 

agreement dated February 5, 2004, the 


pwalker on PRODPC60 with PROPOSALS3
Federal Register / Vol. 71, No. 193 / Thursday, October 5, 2006 / Proposed Rules 58957 

Service agreed to reevaluate the need for 

critical habitat for this species and, if 

prudent, submit a proposed designation 

of critical habitat to the Federal Register 

by September 30, 2006, and a final 

designation by October 1, 2007. This 

document constitutes our new prudency 

determination and our proposed rule to 

designate critical habitat for the guajo ́n, 

and fulfills the settlement agreement. 

For more information on previous 

Federal actions concerning the guajo ́n, 

refer to the final listing rule (62 FR 

31757). 

Critical Habitat 

Critical habitat is defined in section 3 

of the Act as: (i) The specific areas 

within the geographical area occupied 

by a species, at the time it is listed in 

accordance with the Act, on which are 

found those physical or biological 

features (I) Essential to the conservation 

of the species and (II) that may require 

special management considerations or 

protection; and (ii) specific areas 

outside the geographical area occupied 

by a species at the time it is listed, upon 

a determination that such areas are 

essential for the conservation of the 

species. ‘‘Conservation’’ means the use 

of all methods and procedures that are 

necessary to bring an endangered or a 

threatened species to the point at which 

listing under the Act is no longer 

necessary. 

Critical habitat receives protection 

under section 7 of the Act through the 

prohibition against destruction or 

adverse modification of critical habitat 

with regard to actions carried out, 

funded, or authorized by a Federal 

agency. Section 7 requires consultation 

on Federal actions that are likely to 

result in the destruction or adverse 

modification of critical habitat. The 

designation of critical habitat does not 

affect land ownership or establish a 

refuge, wilderness, reserve, preserve, or 

other conservation area. Such 

designation does not allow government 

or public access to private lands. 

Section 7 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 at the time of 

listing must first have features that are 

essential to the conservation of the 

species. Critical habitat designations 

identify, to the extent known using the 

best scientific data available, habitat 

areas that provide essential life cycle 

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

are found the primary constituent 

elements or PCEs, as defined at 50 CFR 

424.12(b)). 

Habitat occupied at the time of listing 

may be included in critical habitat only 

if the essential features thereon may 

require special management or 

protection. Thus, we do not include 

areas where existing management is 

sufficient to conserve the species. (As 

discussed below, such areas may also be 

excluded from critical habitat under 

section 4(b)(2) of the Act.) Furthermore, 

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. 

However, an area that is currently 

occupied by the species but was not 

known to be occupied at the time of 

listing will likely be essential to the 

conservation of the species and, 

therefore, 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 habitats, 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. 

Prudency Determination 

Section 4(a)(3) of the Act and its 

implementing regulations (50 CFR 

424.12) require that, to the maximum 

extent prudent and determinable, we 

designate critical habitat at the time a 

species is listed as endangered or 

threatened. Our regulations at 50 CFR 

424.12(a)(1) state that the designation of 

critical habitat is not prudent when one 

or both of the following situations exist: 

(1) The species is threatened by taking 

or other activity and the identification 

of critical habitat can be expected to 

increase the degree of threat to the 

species; or (2) such designation of 

critical habitat would not be beneficial 

to the species. In our June 11, 1997 final 

rule (62 FR 31757), we determined that 

designation of critical habitat for the 

guajo ́n was not prudent because of 

increased risks of vandalism and illegal 

collection should the exact location of 

individuals be made public. 

Critical habitat designation may 

provide additional information to 

individuals, local and State 

governments, and other entities engaged 

in long-range planning, because areas 

with features essential to the 

conservation of the guajo ́n are clearly 

delineated and the primary constituent 

elements of the habitat necessary for the 

survival of the species are specifically 

identified. Moreover, we do not have 

specific evidence of taking, collection, 


pwalker on PRODPC60 with PROPOSALS3
58958 Federal Register / Vol. 71, No. 193 / Thursday, October 5, 2006 / Proposed Rules 

vandalism, trade, or unauthorized 

human disturbance affecting the guajo ́n. 

Without such evidence, we cannot say 

that designation would increase the 

likelihood of take. Accordingly, we 

withdraw our previous determination 

that the designation of critical habitat 

will increase the degree of threat to the 

species. We determine that the 

designation of critical habitat is prudent 

for this species. At this time, we have 

sufficient information necessary to 

identify specific areas that meet the 

definition of critical habitat and are, 

therefore, proposing critical habitat for 

the guajo ́n. 

Methods 

As required by section 4(b) of the Act, 

we used the best scientific data 

available in determining areas that 

contain the physical and biological 

features essential to the conservation of 

the guajo ́n (see Primary Constituent 

Elements section) and other areas that 

are essential to the conservation of this 

species. We have also reviewed 

available information that pertains to 

the habitat requirements of this species. 

This information included peerreviewed scientific publications; 

unpublished reports from resource 

agencies and universities; field surveys 

and reports; information and maps from 

Puerto Rico Department of Natural and 

Environmental Resources, the Puerto 

Rico Planning Board, Puerto Rico 

Conservation Trust (PRCT), and U.S. 

Geological Survey topographic maps 

(scale 1:20,000); recent aerial photos; 

unpublished data and observations 

collected by Service biologists during 

recent field surveys; forest management 

plans from local agencies; the species’

recovery plan; information received 

from local biologists and researchers 

who have worked with the species and 

its habitat; and information gathered 

during site visits to currently occupied 

sites. All information was used to 

determine the guajo ́n’s currently 

occupied range and habitat features 

needed to support the necessary 

biological functions of the species. We 

are not proposing any areas outside the 

geographical area presently occupied by 

the species because none were found to 

be essential to the conservation of the 

species, however, we are proposing 

three small units that were not known 

to be occupied at the time of listing but 

are currently occupied. 

Primary Constituent Elements for the 

Guajo ́n 

In accordance with section 3(5)(A)(i) 

of the Act and regulations at 50 CFR 

424.12, we are required to base critical 

habitat determinations on the best 

scientific data available and to consider, 

within areas occupied by the species at 

the time of listing, those physical and 

biological features that are essential to 

the conservation of the species (PCEs), 

and that may require special 

management considerations and 

protection. These include, but are not 

limited to, space for individual and 

population growth and for normal 

behavior; food, water, air, light, 

minerals, or other nutritional or 

physiological requirements; cover or 

shelter; sites for breeding, reproduction, 

and rearing (or development) of 

offspring; and habitats that are protected 

from disturbance or are representative of 

the historic geographical and ecological 

distributions of a species. All areas 

proposed as critical habitat for the 

guajo ́n are currently occupied, within 

the species’ historic geographic range, 

and contain sufficient PCEs to support 

at least one life history function. 

The distribution of the guajo ́n is 

associated with the granitic and 

plutonic rocks found in the Cuchilla de 

Panduras mountain range in 

southeastern Puerto Rico. The habitat of 

the guajo ́n lies within several life zones 

as described by Ewel and Whitmore 

(1973, pp. 20–49). The variables used to 

delineate any given life zone are mean 

annual precipitation and mean annual 

temperature. The two predominant life 

zones found within guajo ́n habitat are 

Subtropical Moist and Subtropical Wet 

forests. Trees up to 65.6 ft (20 m) tall, 

with rounded crowns, characterize the 

Subtropical Moist Forest life zone. 

Many of the woody species are 

deciduous during the dry season. The 

abundant moisture of the Subtropical 

Wet Forest life zone is evident in the 

character of its vegetation. Epiphytic 

ferns, bromeliads, and orchids are 

common, the forests are relatively rich 

in plant species, and the growth rates of 

successional trees are rapid. This type of 

forest contains more than 150 species of 

trees that form a dark, complete canopy 

at about 65.6 ft (20 m). 

The guajo ́n is found at low and 

intermediate elevations up to 1,312.3 ft 

(400 m) above sea level (Burrowes 1997, 

p. 52; Burrowes et al. 2004, p. 145; 

Rivero 1998, p. 13), where it inhabits 

caves formed by large boulders of 

granite rock, and in associated streams 

with patches of rock without cave 

systems (Burrowes and Joglar 1999, p. 

706; Vega-Castillo 2000, p. 35; C. RuizLebro ́n, pers. comm., 2006). Caves are 

dark inside, although some light enters 

through gaps formed from the union of 

two or more boulders. Structurally, the 

caves are complex, having several 

chambers of irregular shape and size, 

and may be at different depths between 

the surface of the ground and stream 

(Burrowes 2000, p. 376). The ecological 

conditions of the caves are relatively 

uniform; mean temperature and relative 

humidity are the same at any given 

month of the year, and the caves do not 

have thermal stratification (Rogowitz et 

al. 1999, p. 179; Rogowitz et al. 2001, 

pp. 542, 545; Burrowes 1997, p. 74). 

In streams, the guajo ́n has been found 

only in patches of rock in the streambed 

(Vega-Castillo 2000, pp. 36, 40). The 

streams can be perennial, or they can be 

ephemeral, formed during heavy rain. 

The streams are surrounded by 

secondary forest. Rocks in the 

streambed form crevices and grottoes. 

Streams provide a wide variety of retreat 

sites for the species, such as vegetationcovered rocks (e.g., rocks covered with 

moss, ferns, and liverworts) that help 

conserve humidity. Temperature and 

relative humidity at streams vary with 

the months of the year. The foraging 

habitat of the guajo ́n may extend 

laterally from the edge of streambed (or 

other water source) as far as 66 to 99 ft 

(20 to 30 m) into adjacent vegetated 

areas (Vega-Castillo, pers. obs., 2001). In 

rocky stream habitat, frogs leave their 

retreat site at dusk to forage actively 

over rocks and vegetation. 

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 PCEs for the guajo ́n are: 

(1) Subtropical forest (which may 

include trees such as Cecropia 

schreberiana, Dendropanax arboreus, 

Guarea guidonia, Piper aduncum, 

Spathodea campanulata, Syzygium 

jambos, and Thespesia populnea) at 

elevations from 118 to 1,183 ft (36 to 

361 m) above sea level. 

(2) Plutonic, granitic, or sedimentary 

rocks/boulders that form caves, crevices, 

and grottoes (interstitial spaces) in a 

streambed; and that are in proximity, or 

connected, to a permanent, ephemeral, 

or subterranean clear-water stream or 

water source. The interstitial spaces 

between or underneath rocks provide 

microenvironments characterized by 

generally higher humidity and cooler 

temperatures than outside the rock 

formations. 

(3) Vegetation-covered rocks (the 

vegetation typically includes moss, 

ferns, and hepatics such as Thuidium 

urceolatum, Taxilejeunea sulphurea, 

and Huokeria acutifolia) extending 

laterally to a maximum of 99 ft (30 m) 

on each bank of the stream; these rocks 

provide cover and foraging sites and 

help conserve humidity. 

This proposed designation is designed 

for the conservation of PCEs necessary 


pwalker on PRODPC60 with PROPOSALS3
Federal Register / Vol. 71, No. 193 / Thursday, October 5, 2006 / Proposed Rules 58959 

to support the life history functions of 

the guajo ́n. Because not all life history 

functions require all the PCEs, not all 

proposed critical habitat will contain all 

the PCEs. 

Units are designated based on 

sufficient PCEs being present to support 

one or more of the species’ life history 

functions. Some units contain all PCEs 

and support multiple life processes, 

while some units contain only a portion 

of the PCEs necessary to support the 

species’ particular use of that habitat. 

Where a subset of the PCEs is present at 

the time of designation, this rule 

protects those PCEs 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 used the best scientific data 

available in determining areas that 

contain the features that are essential to 

the conservation of the guajo ́n. We are 

not proposing to designate any areas 

outside the geographical area presently 

occupied by the species. 

We began our analysis by considering 

the historic distribution of and sites 

occupied by the species at the time of 

listing. We reviewed existing 

information to identify the historic 

distribution and sites occupied by the 

guajo ́n at the time of listing. We also 

reviewed available information 

pertaining to the habitat requirements of 

this species. This information included 

literature cited in the final listing rule 

and the final recovery plan, site records, 

published scientific reports, recent 

aerial photos, materials submitted by 

other agencies for development project 

reviews, U.S. Geological Survey (USGS) 

topographic maps (scale 1:20,000), and 

office Geographic Information System 

(GIS) layers. 

An area was considered for 

designation if: (1) It was occupied by the 

guajo ́n at the time of listing and 

possessed at least one or more of the 

PCEs; or (2) was not occupied at the 

time of listing, but is currently occupied 

by the guajo ́n, and has been determined 

to be essential to the conservation of the 

species. These areas were deemed 

essential based on their ability to 

support life history and populationlevel functions for the guajo ́n, as well as 

the need for sufficient habitat to protect 

existing populations. 

We selected areas of habitat known to 

be currently occupied by the species, 

based on field reports from the Puerto 

Rico Department of Natural and 

Environmental Resources (DNER) and 

the PRCT, field visits from Service 

personnel, information from species’

experts, and data cited in the scientific 

literature. Field reconnaissance was 

done in all areas for verification of 

presence/absence. Presence of the 

guajo ́n was documented by listening to 

the distinctive call of the males. 

Based on this review and visual 

inspection of sites where the guajo ́n was 

found, we identified 12 units that 

contain one or more of the PCEs. Areas 

not containing the PCEs are not 

included in the proposal. Such areas 

include high-flow streams and rivers; 

drainages with little or no vegetative 

cover; and drainages with rocks that 

were small, dispersed, or not forming 

crevices and grottoes. One area in the 

municipality of Maunabo and one area 

in the municipality of Patillas that were 

occupied by the guajo ́n at the time of 

listing do not currently contain PCEs 

and the guajo ́n was not observed or 

recorded in consecutive visits to these 

sites in March and April 2006. 

Therefore we are not including either of 

these areas in our proposed designation. 

Boundaries for each unit were 

determined based on known guajo ́n 

sightings, topographical features known 

to be needed by the species, the range 

of elevations used by the species, and 

visual inspection of the units. This 

habitat includes streams with patches of 

rocks and associated riparian vegetation 

that provides foraging habitat for the 

guajo ́n. We have included a foraging 

area of 99 ft (30 m) along creeks and 

drainages as a result of observations by 

experts that the foraging habitat of the 

guajo ́n may extend outside the 

streambed in vegetated areas as far as 30 

meters from the water source (VegaCastillo, pers. obs., 2001). Data layers 

defining map units were created by 

delineating habitats that contained at 

least one or more of the PCEs identified 

above over USGS topographic maps 

(UTM 19, NAD 83). Municipal 

boundaries, rivers, and creeks layers 

were provided by the Puerto Rico 

Planning Board (PRPB) but adapted and 

verified over a base map of USGS 

1:20,000 quadrangles. The roads layer 

was created at the Boquero ́n Field Office 

using a base map of USGS 1:20,000 

quadrangles. Quadrangles used were: 

Humacao, Punta Guayane ́s, Juncos, 

Yabucoa, Punta Tuna, and Patillas. 

We propose to designate critical 

habitat on lands that we have 

determined were occupied at the time of 

listing and contain sufficient primary 

constituent elements to support life 

history functions essential for the 

conservation of the species (9 units), 

and additional areas not occupied at the 

time of listing that provide habitat 

essential to the conservation of the 

species (3 units). The 12 units that we 

are proposing as critical habitat 

encompass approximately 217.2 ac (88 

ha) within the municipalities of 

Humacao, Las Piedras, Maunabo, 

Patillas, and Yabucoa. The proposed 

units contain habitat that supports 

biological and population-level 

functions (including needs for food, 

shelter, breeding sites, foraging, and 

population expansion) of the guajo ́n. 

Changes in the composition and 

abundance of vegetation surrounding 

guajo ́n habitat, degradation of water 

quality due to agricultural practices 

(e.g., use of herbicides, fertilizers, or 

insecticides), and pollution of streams 

caused by human refuse are threats to 

the guajo ́n that require special 

management. A brief discussion of each 

unit proposed as critical habitat is 

provided in the unit descriptions below. 

When determining proposed critical 

habitat boundaries, we made every 

effort to avoid proposing the designation 

of developed areas such as buildings or 

houses, paved areas, and other 

structures that lack PCEs for the guajo ́n. 

When it has not been possible to map 

out these structures and the land upon 

which they are sited because of scale 

issues, they have been excluded from 

the proposed designation by rule text. 

Therefore, Federal actions limited to 

these areas would not trigger section 7 

consultation, unless they affect the 

species and/or PCEs in adjacent critical 

habitat. 

Special Management Considerations or 

Protection 

When designating critical habitat, we 

assess whether the areas determined to 

be occupied at the time of listing and 

containing the PCEs may require special 

management considerations or 

protection. As discussed in more detail 

in the unit description below, we find 

that units occupied at the time of listing 

(Units 1, 2, 4, 5, 6, 7, 8, 9, and 10) may 

require special management 

considerations or protection due to 

threats to the guajo ́n and/or its habitat. 

All these proposed units are adjacent to 

agricultural lands, roads, trails, homes, 

or other manmade structures. 

Management considerations and 

protection include protection of the 

guajo ́n and its habitat from threats 

posed by deforestation and earth 

movement near streams for road 

construction, and for agricultural, 

urban, and rural development. These 

threats may result in changes in the 

composition and abundance of 

vegetation surrounding guajo ́n habitat, 

as well as degradation of water quality 

from illegal garbage dumping, untreated 

sewage, and agricultural practices (e.g., 

use of herbicides, fertilizers, or 

insecticides).

Proposed Critical Habitat Designation 

We are proposing 12 units as critical 

habitat for the guajo ́n. The critical 

habitat areas described below constitute 

our best assessment at this time of areas 

determined to be occupied at the time 

of listing, contain the primary 

constituent elements, and that may 

require special management (9 units), 

and those additional areas that were not 

occupied at the time of listing but were 

found to be essential to the conservation 

of the guajo ́n (3 units). The 12 areas 

proposed as critical habitat are: 

Mariana, Montones, Tejas, Emajagua, 

Jacaboa, Calabazas, Guayane ́s, Panduras, 

Talante, Guayabota, Guayabito, and 

Guayabo Units.

We present brief descriptions of all 

units, the primary constituent elements 

they contain, and reasons why they 

meet the definition of critical habitat for 

the guajo ́n, below. Universal Transverse 

Mercator (UTM) coordinates and more 

precise legal descriptions of each unit 

are provided in the Proposed Regulation 

Promulgation section. 

Unit 1: Mariana Unit 

Unit 1 consists of approximately 23.6 

ac (9.6 ha) located south of Road PR–

909, west of Road PR–3, and north of 

Quebrada Catan ̃ ao within Mariana 

Ward, Humacao. Unit 1 contains 5,412.8 

ft (1,649.8 m) of an unnamed, rocky 

stream with abundant water, a guajo ́n 

foraging area extending laterally 99 ft 

(30 m) from each bank of the stream, 

and secondary forest on all sides of the 

stream. This unit was known to be 

occupied at the time of listing (J. 

Sustache, DNER database, 1996). Every 

PCE is found within this unit, and 

presence of the species and PCEs at this 

site was confirmed by the Service in 

March 2006. Threats that may require 

special management considerations, due 

to the proximity of Unit 1 to urbanized 

areas and infrastructure (e.g., major 

roads), include changes in the 

composition and abundance of 

vegetation surrounding guajo ́n habitat 

(PCEs 1 and 3), degradation of water 

quality due to agricultural practices 

(e.g., use of herbicides, fertilizers, or 

insecticides), and pollution of streams 

caused by human refuse (PCE 2). 

Unit 2: Montones Unit 

Unit 2 consists of approximately 31.1 

ac (12.6 ha) in Montones Ward, Las 

Piedras. It contains 6,941.7 ft (2,115.8 

m) of the headwaters of the Valenciano 

River in the vicinity of PR 917 Km 9.7, 

and a guajo ́n foraging area of 99 ft (30 

m) on each side of the river. This unit 

was known to be occupied at the time 

of listing (F. Bird-Pico ́, DNER database, 

1996). Although some sections of this 

unit do not contain PCE 1, all other 

PCEs are found within this unit (a rocky 

stream with abundant water surrounded 

by secondary forest, and a rocky creek 

surrounded by vines, herbaceous 

vegetation, shrubs, and trees). In some 

areas of the creek, the water disappears 

underground and reappears at various 

intervals. The presence of the species 

and PCEs at this site was confirmed by 

the Service in March 2006. Threats that 

may require special management 

considerations, due to the proximity of 

Unit 2 to urbanized areas and 

infrastructure (e.g., roads), include 

changes in the composition and 

abundance of vegetation surrounding 

guajo ́n habitat (PCE 1 and 3), 

degradation of water quality due to 

agricultural practices (e.g., use of 

herbicides, fertilizers, or insecticides), 

and pollution of streams caused by 

human refuse (PCE 2). 

Unit 3: Tejas Unit 

Unit 3 consists of approximately 5.2 

ac (2.1 ha) located between Road PR–

905 to the east, Road PR–908 to the 

west, Road PR–9921 to the north, and 

Road PR–9904 to the south within Tejas 

Ward, Las Piedras. It contains 1,312 ft 

(400 m)) of an unnamed tributary of the 

Rı ́o Humacao, and a guajo ́n foraging 

area of 99 ft (30 m) on each side of the 

tributary. This unit was not known to be 

occupied at the time of listing. Every 

PCE is found within this unit (the area 

contains a rocky creek surrounded by 

vines, herbaceous vegetation, shrubs, 

and trees), and this was confirmed by 

the Service in March 2006. Unit 3 is 

essential to the conservation of the 

guajo ́n. The guajo ́n was listed under the 

Act primarily due to its highly restricted 

geographical distribution and its 

specialized habitat requirements (Joglar 

1998, p. 73). Thus, protection of all 

existing populations of the guajo ́n is 

important to the conservation of the 

species. The habitat of this species is 

naturally fragmented, and the majority 

of the known populations are on private 

land where increased levels of land 

development in southeastern Puerto 

Rico are occurring where the species 

occurs, and threaten to further reduce 

and fragment the species’ habitat, 

distribution, and survival (Joglar 1998, 

p. 73). Being a habitat specialist, the 

guajo ́n is adapted to particular 

environmental conditions, and abrupt 

changes in these conditions could result 

in population declines. Additionally, 

fragmenting habitat through human 

intrusions, such as roads, makes 

populations less resilient to natural 

population declines (Pechman et al. 

1991, p. 895). Because it is occupied by 

the species and contains sufficient PCEs 


pwalker on PRODPC60 with PROPOSALS3
Federal Register / Vol. 71, No. 193 / Thursday, October 5, 2006 / Proposed Rules 58961 

to support the life functions of the 

species, Unit 3 is essential to the 

conservation of the species. 

Unit 4: Emajagua Unit 

Unit 4 consists of approximately 33.0 

ac (13.4 ha) between Quebrada Arenas 

and Quebrada Emajagua, north of Road 

PR–901 (on the periphery of an 

underground tunnel under 

construction), within Emajagua Ward, 

Maunabo. It contains three connected, 

unnamed streams/drainages totaling 

about 7,400 ft (2,256 m), and a guajo ́n 

foraging area of 99 ft (30 m) on each side 

of the streams/drainages. This unit was 

known to be occupied at the time of 

listing (R. Thomas, DNER database, 

1965). Every PCE is found within this 

unit, and presence of the species and 

PCEs at this site was confirmed by the 

Service in April 2006. Threats that may 

require special management 

considerations, due to the proximity of 

Unit 4 to urbanized areas and 

infrastructure (e.g., major roads), 

include changes in the composition and 

abundance of vegetation surrounding 

guajo ́n habitat (PCEs 1 and 3) and 

pollution of streams caused by human 

refuse (PCE 2). 

Unit 5: Jacaboa Unit 

Unit 5 consists of approximately 10.3 

ac (4.2 ha) northwest of road PR–758 

within Rı ́os Ward, Patillas. It contains 

2,334.6 ft (711.6 m) of an unnamed 

rocky drainage to the Jacaboa River, and 

a guajo ́n foraging area of 99 ft (30 m) on 

each side of the drainage. This unit was 

known to be occupied at the time of 

listing (R. Thomas, DNER database, 

1965). Every PCE is found within this 

unit (it contains a rocky creek with 

small and large sedimentary rocks and 

boulders, closed forest canopy over the 

creek, and closed, mature forest along 

the shores, including some bamboo 

stands). The presence of the species and 

PCEs at this site was confirmed by the 

Service in April 2006. Threats that may 

require special management 

considerations, due to the proximity of 

Unit 5 to urbanized areas and 

infrastructure (e.g., roads), include 

changes in the composition and 

abundance of vegetation surrounding 

guajo ́n habitat (PCEs 1 and 3), 

degradation of water quality due to 

agricultural practices (e.g., use of 

herbicides, fertilizers, or insecticides) 

and pollution of streams caused by 

human refuse (PCE 2). 

Unit 6: Calabazas Unit 

Unit 6 consists of approximately 13.8 

ac (5.6 ha) located northeast of road PR–

900, between Quebrada Guayabo to the 

south and Rı ́o Guayane ́s to the north, 

within Calabazas Ward, Yabucoa. The 

unit contains a 3,198 ft (975 m) stretch 

of a rocky creek surrounded by vines, 

herbaceous vegetation, shrubs, and 

trees, and a guajo ́n foraging area of 99 

ft (30 m) on each side of the drainage. 

This unit was known to be occupied at 

the time of listing (J. Montero, DNER 

database, 1988). Every PCE is found 

within this unit, and presence of the 

species and PCEs at this site was 

confirmed by the Service in March 

2006. Threats that may require special 

management considerations, due to the 

proximity of Unit 6 to urbanized areas 

and infrastructure (e.g., roads), include 

changes in the composition and 

abundance of vegetation surrounding 

guajo ́n habitat (PCEs 1 and 3), 

degradation of water quality due to 

agricultural practices (e.g., use of 

herbicides, fertilizers, or insecticides), 

and pollution of streams caused by 

human refuse (PCE 2). 

Unit 7: Guayane ́ s Unit 

Unit 7 consists of approximately 7.9 

ac (3.2 ha) northeast of Road PR–900 

between Quebrada Guayabo to the south 

and Rı ́o Guayane ́s to the north, and 

north of Unit 6, within Calabazas Ward, 

Yabucoa. It contains 4,265 ft (1,300 m) 

of an unnamed drainage, and a guajo ́n 

foraging area of 99 ft (30 m) on each side 

of the drainage. This unit was known to 

be occupied at the time of listing (J. 

Montero, DNER database, 1988). Every 

PCE is found within this unit (it 

contains a rocky creek surrounded by 

vines, herbaceous vegetation, shrubs, 

and trees). The presence of the species 

and PCEs at this site was confirmed by 

the Service in March 2006. Threats that 

may require special management 

considerations, due to the proximity of 

Unit 7 to urbanized areas and 

infrastructure (e.g., roads), include 

changes in the composition and 

abundance of vegetation surrounding 

guajo ́n habitat (PCEs 1 and 3), 

degradation of water quality due to 

agricultural practices (e.g., use of 

herbicides, fertilizers, or insecticides), 

and pollution of streams caused by 

human refuse (PCE 2). 

Unit 8: Panduras Unit 

Unit 8 consists of approximately 28.6 

ac (11.6 ha) to the northwest and 

southeast of Road PR–3 within 

Calabazas Ward, Yabucoa. It contains 

2,314.1 ft (705.6 m) of an unnamed 

drainage, a guajo ́n foraging area of 99 ft 

(30 m) on each side of the drainage, and 

18.2 ac (7.4 ha) of lands owned by the 

PRCT near the top of Cerro La Pandura. 

This unit was known to be occupied at 

the time of listing (J. Rivero 1998, DNER 

database, 1978). Every PCE is found 

within this unit (it contains a rocky area 

with medium and large granite 

boulders, a drainage with closed-canopy 

forest over the drainage, and closed, 

mature forest along the edges). The 

presence of the species and PCEs at this 

site was confirmed by the Service in 

March 2006. Threats that may require 

special management considerations, due 

to the proximity of Unit 8 to urbanized 

areas and infrastructure (e.g., roads), 

include changes in the composition and 

abundance of vegetation surrounding 

guajo ́n habitat (PCEs 1 and 3) and 

pollution of streams caused by human 

refuse (PCE 2). This area does not 

currently have a management plan 

(Fernando Silva, pers. comm., 2006). 

Unit 9: Talante Unit 

Unit 9 consists of approximately 23.5 

ac (9.5 ha) east of Road PR–3 within 

Calabazas Ward and Talante Ward, 

Yabucoa. It contains the headwaters of 

the Talante Creek, five unnamed 

drainages (totaling about 3,500 ft (1,061 

m)), and a guajo ́n foraging area of 99 ft 

(30 m) on each side of the creek and 

drainages. About 2.8 ac (1.1 ha) of Unit 

9 are within Calabazas Ward, and the 

remaining 21.6 ac (8.7 ha) are within 

Talante Ward. This unit was known to 

be occupied at the time of listing (J. 

Rivero 1998, DNER database, 1978). 

Every PCE is found within this unit (it 

contains drainages with medium and 

large granite boulders that are 

surrounded by vines, herbaceous 

vegetation, shrubs, and trees, and that 

connect to a small rocky creek; some 

patches contain big rocks that are 

completely exposed to the sun or 

covered with vines). The presence of the 

species and PCEs at this site was 

confirmed by the Service in April 2006. 

Threats that may require special 

management considerations, due to the 

proximity of Unit 9 to urbanized areas 

and infrastructure (e.g., major roads), 

include changes in the composition and 

abundance of vegetation surrounding 

guajo ́n habitat (PCEs 1 and 3), 

degradation of water quality due to 

agricultural practices (e.g., use of 

herbicides, fertilizers, or insecticides) 

and pollution of streams caused by 

human refuse (PCE 2). 

Unit 10: Guayabota Unit 

Unit 10 consists of approximately 

13.1 ac (5.3 ha) northeast of intersection 

of roads PR–181 and PR–182, and south 

of the municipal boundary with San 

Lorenzo, within Guayabota Ward, 

Yabucoa. It contains a small unnamed 

creek (about 700 ft (212 m)), and a 

guajo ́n foraging area of 99 ft (30 m) on 

each side of the creek. This unit was 

known to be occupied at the time of 


pwalker on PRODPC60 with PROPOSALS3
58962 Federal Register / Vol. 71, No. 193 / Thursday, October 5, 2006 / Proposed Rules 

listing (J. Rivero, DNER database, 1980; 

Burrowes 1997). Every PCE is found 

within this unit. The northwest section 

of the rocky creek (large and medium 

granite boulders) is surrounded by 

closed canopy over the creek, with 

herbaceous vegetation and some trees 

along the shore. The southeastern 

section of the rocky creek has large and 

medium sedimentary boulders and is 

surrounded by semi-closed canopy over 

the creek and shores that are primarily 

exposed to the sun, with some areas 

covered with grass. The presence of the 

species and PCEs at this site was 

confirmed by the Service in April 2006. 

Threats that may require special 

management considerations, due to the 

proximity of this unit to urbanized areas 

and infrastructure (e.g., roads), include 

changes in the composition and 

abundance of vegetation surrounding 

guajo ́n habitat (PCEs 1 and 3), 

degradation of water quality due to 

agricultural practices (e.g., use of 

herbicides, fertilizers, or insecticides), 

and pollution of streams caused by 

human refuse (PCE 2). 

Unit 11: Guayabito Unit 

Unit 11 consists of approximately 

17.3 ac (7.0 ha) south of Road PR–900 

and north of the Maunabo boundary, 

within Guayabota Ward, Yabucoa. It 

contains 1,232.6 ft (4,042 m) of an 

unnamed drainage and tributary that 

connect to Quebrada Guayabo, and a 

guajo ́n foraging area of 99 ft (30 m) on 

each side of both the drainage and 

tributary. This unit was not known to be 

occupied at the time of listing. The unit 

is split into a rocky drainage to the west 

(large, clumped, granite boulders), and a 

rocky creek to the east (large granite 

boulders). Both are surrounded by 

closed canopy over the drainage and 

creek, and closed mature forest along 

the shores. Thus, every PCE is found 

within this unit, and presence of the 

species and PCEs at this site was 

confirmed by the Service in April 2006. 

Unit 11 is essential to the conservation 

of the guajo ́n for several reasons. The 

boulders and closed canopy provide the 

essential habitat for guajo ́n reproduction 

and foraging. The guajo ́n was listed 

primarily due to its highly restricted 

geographical distribution and habitat 

requirements (Joglar 1998, p. 73). The 

habitat of this species is naturally 

fragmented, and the majority of the 

known populations are on private land, 

where the increased levels of land 

development currently occurring in 

southeastern Puerto Rico threatens to 

further reduce and fragment the species’

habitat, distribution, and survival (Joglar 

1998, p. 73). Being a habitat specialist, 

the guajo ́n is adapted to particular 

environmental conditions, and abrupt 

changes in these conditions could result 

in population declines. Additionally, 

fragmenting habitat through human 

intrusions such as roads makes 

populations less resilient to natural 

population declines (Pechman et al. 

1991, p. 895). Protection of all existing 

populations of the guajo ́n is extremely 

important due to its limited distribution 

and the specialized habitat it occupies. 

Unit 12: Guayabo Unit 

Unit 12 consists of approximately 

9.8 ac (3.9 ha) along Quebrada Guayabo, 

along and south of Road PR–900 in 

Guayabota Ward, Yabucoa. It contains 

2,247.5 ft (685 m) of the 

southwesternmost section of Quebrada 

Guayabo, and a guajo ́n foraging area of 

99 ft (30 m) on each side of the stream. 

This unit was not known to be occupied 

at the time of listing. Every PCE is found 

within this unit and presence of the 

species and PCEs at this site was 

confirmed by the Service in April 2006. 

Unit 12 is essential to the conservation 

of the guajo ́n because it contains the 

PCEs (a rocky stream surrounded by 

closed canopy over the stream, and 

closed mature forest along the shores 

that provide the habitat essential to the 

guajo ́n for food, shelter, breeding, 

foraging, and population expansion), 

and because it is occupied. Due to the 

species’ limited distribution and the 

specialized habitat it occupies, 

protection of all existing populations of 

the guajo ́n is extremely important to 

conservation of the species. 

The habitat of this species is naturally 

fragmented, and remaining habitat is 

threatened by land development which 

can further reduce and fragment the 

species’ habitat, distribution, and 

survival (Joglar 1998, p. 73). Being a 

habitat specialist, the guajo ́n is adapted 

to particular environmental conditions, 

and abrupt changes in these conditions 

could result in population declines. 

Additionally, fragmenting habitat 

through human intrusions, such as 

roads, makes populations less resilient 

to natural population declines 

(Pechman et al. 1991, p. 895). 

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 et 

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

Under 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 PCEs 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 proposed 

species or result in destruction or 

adverse modification of proposed 

critical habitat. This is a procedural 

requirement only. However, once 

proposed species become listed, or 

proposed critical habitat is designated 

as final, the full prohibitions of section 

7(a)(2) 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 


pwalker on PRODPC60 with PROPOSALS3
Federal Register / Vol. 71, No. 193 / Thursday, October 5, 2006 / Proposed Rules 58963 

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 

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) 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 may affect, but 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 instances where a new 

species is listed or critical habitat is 

subsequently designated that may be 

affected and the Federal agency has 

retained discretionary involvement or 

control over the action or such 

discretionary involvement or control is 

authorized by law. Consequently, 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 the 

guajo ́n 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 the Guajo ́n 

and Its Critical Habitat 

Jeopardy Standard 

Prior to and following designation of 

critical habitat, the Service has applied 

an analytical framework for guajo ́n 

jeopardy analyses that relies heavily on 

the importance of populations to the 

survival and recovery of the guajo ́n. 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 the guajo ́n 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 population(s), inclusive of 

associated habitat conditions, a jeopardy 

finding is considered to be warranted, 

because of the relationship of each 

population to the survival and recovery 

of the species as a whole. 

Adverse Modification Standard 

The analytical framework described 

in the Director’s December 9, 2004, 

memorandum is used to complete 

section 7(a)(2) analyses for Federal 

actions affecting critical habitat for the 

guajo ́n. 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 critical habitat units is to support 

viable populations of the guajo ́n. 

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 PCEs to 

an extent that the conservation value of 

critical habitat for the guajo ́n is 

appreciably reduced. Activities that, 

when carried out, funded, or authorized 

by a Federal agency, may affect critical 

habitat for the guajo ́n include, but are 

not limited to: 

(1) Activities that would significantly 

alter the vegetation structure in and 

around creeks, streams, and drainages. 

Such activities could include, but are 

not limited to, vegetation cutting for 

expanding or maintaining roads, 

development of new roads and trails, 

and construction of new homes and 

commercial establishments. The 

elimination or alteration of vegetation 

structure could result in habitat 

fragmentation that may interrupt the 

connection between populations, alter 

guajo ́n foraging activities and the 

availability of foraging resources, reduce 

the quality of breeding microhabitat 

(e.g., change in temperature and 

humidity levels within breeding 

crevices and caves), and result in direct 

mortality of individuals through 

trampling or crushing, or desiccation 

from sun exposure. 


pwalker on PRODPC60 with PROPOSALS3
58964 Federal Register / Vol. 71, No. 193 / Thursday, October 5, 2006 / Proposed Rules 

(2) Activities that may alter the 

natural flow of water. Such activities 

could include, but are not limited to, 

stream modifications related to the 

expansion or maintenance of roads, 

development of new roads and trails, 

and construction of new homes and 

commercial establishments. Alteration 

of water flow may result in drowning of 

adults and loss of egg clutches through 

erosion and increase flash flooding, 

abandonment of suitable habitat and 

establishment into less-favorable areas, 

and reduction of breeding activities 

(e.g., insufficient or excessive humidity 

for proper egg development). 

(3) Activities that may reduce the 

quality of water. Such activities could 

include, but are not limited to, 

recreational activities within major 

streams and rivers connecting drainages 

and tributaries used by the species, 

agricultural practices (e.g., use of 

pesticides, herbicides, or fertilizers), 

and pollution of streams caused by 

human refuse. 

(4) Activities that eliminate or 

degrade the natural connection between 

guajo ́n populations. Such activities 

could include, but are not limited to, 

vegetation cutting for expanding or 

maintaining roads, development of new 

roads and trails, and construction of 

new homes and commercial 

establishments. These activities may 

interrupt the connection between 

existing populations; thus, dispersal and 

interaction between sub-populations 

could be affected, restricting gene flow 

and jeopardizing the integrity of the 

species’ gene pool. 

We consider the proposed 12 critical 

habitat units to be currently occupied by 

the guajo ́n, based on peer-reviewed 

scientific publications; unpublished 

reports from resource agencies, nongovernment organizations, and 

universities; field surveys and reports; 

and field inspections by Service 

personnel. All of the units included in 

this proposed designation contain the 

features that are essential to the 

conservation of the guajo ́n or are 

essential to the conservation of the 

species. Federal agencies already 

consult with us on activities in areas 

currently occupied by the guajo ́n, or if 

the species may be affected by the 

action, to ensure that their actions do 

not jeopardize the continued existence 

of the guajo ́n. 

Application of Section 3(5)(A) and 

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

Act 

Section 3(5)(A) of the Act defines 

critical habitat as the specific areas 

within the geographical area occupied 

by the species on which are found those 

physical and biological features (i) 

Essential to the conservation of the 

species, and (ii) which may require 

special management considerations or 

protection. Therefore, areas within the 

geographical area occupied by the 

species that do not contain the features 

essential to the conservation of the 

species are not, by definition, critical 

habitat. Similarly, areas within the 

geographical area occupied by the 

species that require no special 

management or protection also are not, 

by definition, critical habitat. Thus, for 

example, areas that do not need special 

management may not need protection if 

there is lack of pressure for change, such 

as areas too remote for anthropogenic 

disturbance. 

There are multiple ways to provide 

management for species’ habitat. 

Statutory and regulatory frameworks 

that exist at a local level can provide 

such protection and management, as can 

lack of pressure for change, such as in 

areas too remote for anthropogenic 

disturbance. Finally, State, local, or 

private management plans as well as 

management under Federal agencies’

jurisdictions can provide protection and 

management to avoid the need for 

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 

or protection 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 or protection 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. In this proposed 

designation of critical habitat for the 

guajo ́n, we are not considering the noninclusion of any units on the basis of 

adequate management plans, under 

section 3(5)(A) of the Act. 

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

critical habitat shall be designated, and 

revised, on the basis of the best 

available scientific data after taking into 

consideration the economic impact, 

national security impact, and any other 

relevant impact, of specifying any 

particular area as critical habitat. 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 section 4(b)(2) the Secretary has 

discretion as to which factors to 

consider and how much weight will be 

given to any factor. Under section 

4(b)(2), 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 this 

proposed designation of critical habitat 

for the guajo ́n, we are not considering or 

proposing any exclusions pursuant to 

section 4(b)(2) of the Act. However, we 

will be conducting an economic 

analysis of the impacts of the proposed 

critical habitat designation and related 

factors, which will be made available for 

public review and comment. Based on 

public comment on that document, the 

proposed designation, and the 

information in the final economic 

analysis, areas 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. Under 50 CFR 424.19, we 

must propose an area as critical habitat, 

and receive public comment on that 

action, prior to making an exclusion of 

that area under section 4(b)(2) of the Act 

from the final critical habitat 

designation. 

Economic Analysis 

An analysis of the economic impacts 

of proposing critical habitat for the 

guajo ́n 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.southeast.fws.gov, or by contacting 

the Boquero ́n Field Office directly (see 

ADDRESSES).

Federal Register / Vol. 71, No. 193 / Thursday, October 5, 2006 / Proposed Rules 58965 

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. Copies of 

this proposed rule will be sent to these 

peer reviewers, immediately following 

publication in the Federal Register. We 

will invite these peer reviewers to 

comment, during the public comment 

period, on the specific assumptions and 

conclusions regarding the proposed 

designation of critical habitat. 

We will consider all comments and 

information received during the 

comment period on this proposed rule 

during preparation of a final 

rulemaking. Accordingly, the final 

decision may differ from this proposal. 

Public Hearings 

The Act provides for one or more 

public hearings on this proposal, if 

requested. Requests for public hearings 

must be made in writing at least 15 days 

prior to the close of the public comment 

period. We will schedule public 

hearings on this proposal, if any are 

requested, and announce the dates, 

times, and places of those hearings in 

the Federal Register and local 

newspapers at least 15 days prior to the 

first hearing. 

Clarity of the Rule 

Executive Order 12866 requires each 

agency to write regulations and notices 

that are easy to understand. We invite 

your comments on how to make this 

proposed rule easier to understand, 

including answers to questions such as 

the following: (1) Are the requirements 

in the proposed rule clearly stated? (2) 

Does the proposed rule contain 

technical jargon that interferes with the 

clarity? (3) Does the format of the 

proposed rule (grouping and order of 

the sections, use of headings, 

paragraphing, and so forth) aid or 

reduce its clarity? (4) Is the description 

of the notice in the SUPPLEMENTARY

INFORMATION section of the preamble 

helpful in understanding the proposed 

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

this proposed rule easier to understand? 

Send a copy of any comments on how 

we could make this proposed rule easier 

to understand to: Office of Regulatory 

Affairs, Department of the Interior, 

Room 7229, 1849 C Street, NW., 

Washington, DC 20240. You may e-mail 

your comments to this address:

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. 

Within these areas, the types of 

Federal actions or authorized activities 

that we have identified as potential 

concerns are listed above in the 

‘‘Adverse Modification Standard’’

section. An announcement will be made 

in the Federal Register and in local 

newspapers when the draft economic 

analysis is available for public review 

and comment. When it is completed, the 

draft economic analysis will be 

available from the Internet Web site at 

http://www.southeast.fws.gov or by 

contacting the Boquero ́n Field Office 

directly (see ADDRESSES). 

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, the 

agency will need to consider alternative 

regulatory approaches. Since the 

determination of critical habitat is a 

statutory requirement pursuant to the 

Act, we must then evaluate alternative 

regulatory approaches, where feasible, 

when promulgating a designation of 

critical habitat. 

In developing our designations of 

critical habitat, we consider economic 

impacts, impacts to national security, 

and other relevant impacts pursuant to 

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

discretion allowable under this 

provision, we may exclude any 

particular area from the designation of 

critical habitat providing that the 

benefits of such exclusion outweigh the 

benefits of specifying the area as critical 

habitat and that such exclusion would 

not result in the extinction of the 

species. As such, we believe that the 

evaluation of the inclusion or exclusion 

of particular areas, or combination 

thereof, in a designation constitutes our 

regulatory alternative analysis. 

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 E.O. 12866. This draft 

economic analysis will provide the 

required factual basis for the RFA 

finding. Upon completion of the draft 

economic analysis, the Service will 

publish a notice of availability of the 

draft economic analysis of the proposed 

designation and reopen the public 

comment period for the proposed 

designation for an additional 60 days. 

The Service will include with the notice 

of availability, as appropriate, an initial 

regulatory flexibility analysis or a 

certification that the rule will not have 

a significant economic impact on a 

substantial number of small entities 

accompanied by the factual basis for 

that determination. The Service has 

concluded that deferring the RFA 

finding until completion of the draft 

economic analysis is necessary to meet 

the purposes and requirements of the 

RFA. Deferring the RFA finding in this 

manner will ensure that the Service 

makes a sufficiently informed 

determination based on adequate 

economic information and provides the 

necessary opportunity for public 

comment.

58966 Federal Register / Vol. 71, No. 193 / Thursday, October 5, 2006 / Proposed Rules 

Executive Order 13211 

On May 18, 2001, the President issued 

an Executive Order (E.O. 13211) on 

regulations that significantly affect 

energy supply, distribution, and use. 

Executive Order 13211 requires agencies 

to prepare Statements of Energy Effects 

when undertaking certain actions. This 

proposed rule to designate critical 

habitat for the guajo ́n is not a significant 

regulatory action under Executive Order 

12866, and it is not expected to 

significantly affect energy supplies, 

distribution, or use. Therefore, this 

action is not a significant energy action 

and no Statement of Energy Effects is 

required. 

Unfunded Mandates Reform Act (2 

U.S.C. 1501 et seq.) 

In accordance with the Unfunded 

Mandates Reform Act 

(2 U.S.C. 1501), the Service makes the 

following findings: 

(a) This rule will not produce a 

Federal mandate. In general, a Federal 

mandate is a provision in legislation, 

statute or regulation that would impose 

an enforceable duty upon State, local, 

tribal governments, or the private sector 

and includes both ‘‘Federal 

intergovernmental mandates’’ and 

‘‘Federal private sector mandates.’’

These terms are defined in 2 U.S.C. 

658(5)–(7). ‘‘Federal intergovernmental 

mandate’’ includes a regulation that 

‘‘would impose an enforceable duty 

upon State, local, or tribal governments’’

with two exceptions. It excludes ‘‘a 

condition of Federal assistance.’’ It also 

excludes ‘‘a duty arising from 

participation in a voluntary Federal 

program,’’ unless the regulation ‘‘relates 

to a then-existing Federal program 

under which $500,000,000 or more is 

provided annually to State, local, and 

tribal governments under entitlement 

authority,’’ if the provision would 

‘‘increase the stringency of conditions of 

assistance’’ or ‘‘place caps upon, or 

otherwise decrease, the Federal 

Government’s responsibility to provide 

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

governments ‘‘lack authority’’ to adjust 

accordingly. At the time of enactment, 

these entitlement programs were: 

Medicaid; AFDC work programs; Child 

Nutrition; Food Stamps; Social Services 

Block Grants; Vocational Rehabilitation 

State Grants; Foster Care, Adoption 

Assistance, and Independent Living; 

Family Support Welfare Services; and 

Child Support Enforcement. ‘‘Federal 

private sector mandate’’ includes a 

regulation that ‘‘would impose an 

enforceable duty upon the private 

sector, except (i) A condition of Federal 

assistance or (ii) a duty arising from 

participation in a voluntary Federal 

program.’’

The designation of critical habitat 

does not impose a legally binding duty 

on non-Federal government entities or 

private parties. Under the Act, the only 

regulatory effect is that Federal agencies 

must ensure that their actions do not 

destroy or adversely modify critical 

habitat under section 7. 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 due to current public 

knowledge of the species’ protection, 

the prohibition against take of the 

species both within and outside of the 

designated areas, and the fact that 

critical habitat provide no incremental 

restrictions, we do not anticipate that 

this rule will significantly or uniquely 

affect small governments. As such, a 

Small Government Agency Plan is not 

required. We will, however, further 

evaluate this issue as we conduct our 

economic analysis and revise this 

assessment if appropriate. 

Executive Order 12630—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 proposing critical 

habitat for the guajo ́n in a takings 

implications assessment. The takings 

implications assessment concludes that 

this designation of critical habitat for 

the guajo ́n does not pose significant 

takings implications. 

Federalism 

In accordance with Executive Order 

13132, the rule does not have significant 

Federalism effects. A Federalism 

assessment is not required. In keeping 

with DOI and Department of Commerce 

policy, we requested information from, 

and coordinated development of, this 

proposed critical habitat designation 

with appropriate State resource agencies 

in Puerto Rico. The designation of 

critical habitat in areas currently 

occupied by the guajo ́n 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 propose 

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 the 

guajo ́n. 

Paperwork Reduction Act of 1995 (44 

U.S.C. 3501 et seq.) 

This rule does not contain any new 

collections of information that require 

approval by OMB under the Paperwork 

Reduction Act. This rule will not 

impose recordkeeping or reporting 

requirements on State or local 

governments, individuals, businesses, or 

organizations. An agency may not 

conduct or sponsor, and a person is not 

required to respond to, a collection of 

information unless it displays a 

currently valid OMB control number. 

National Environmental Policy Act 

It is our position that, outside the 

Tenth Circuit, we do not need to 

prepare environmental analyses as 

defined by the NEPA in connection with 

designating critical habitat under the 

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. 


pwalker on PRODPC60 with PROPOSALS3
Federal Register / Vol. 71, No. 193 / Thursday, October 5, 2006 / Proposed Rules 58967 

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 with features essential for the 

conservation of the guajo ́n. Therefore, 

critical habitat for the guajo ́n has not 

been designated on Tribal lands.

Guajo ́n (Eleutherodactylus cooki) 

(1) Critical habitat units are depicted 

for Humacao, Las Piedras, Maunabo, 

Patillas, and Yabucoa, Puerto Rico, on 

the maps below. 

(2) The primary constituent elements 

of critical habitat for the guajo ́n are the 

habitat components that provide: 

(i) Subtropical forest (which may 

include trees such as Cecropia 

schreberiana, Dendropanax arboreus, 

Guarea guidonia, Piper aduncum, 

Spathodea campanulata, Syzygium 

jambos, and Thespesia populnea) at 

elevations from 118 to 1,183 ft (36 to 

361 m) above sea level; 

(ii) Plutonic, granitic, or sedimentary 

rocks/boulders that form caves, crevices, 

and grottoes (interstitial spaces) in a 

streambed, and that are in proximity, or 

connected, to a permanent, ephemeral, 

or subterranean clear-water stream or 

water source. The interstitial spaces 

between or underneath rocks provide 

microenvironments characterized by 

generally higher humidity and cooler 

temperatures than outside the rock 

formations; and 

(iii) Vegetation-covered rocks (the 

vegetation typically includes moss, 

ferns, and hepatics such as Thuidium 

urceolatum, Taxilejeunea sulphurea, 

and Huokeria acutifolia) extending 

laterally to a maximum of 99 feet (30 

meters) on each bank of the stream. 

These rocks provide cover and foraging 

sites and help conserve humidity. 

(3) Critical habitat does not include 

manmade structures existing on the 

effective date of this rule and not 

containing one or more of the primary 

constituent elements, such as buildings, 

driveways, lawns, aqueducts, airports, 

and roads, and the land on which such 

structures are located. 

(4) Critical habitat maps. Data layers 

defining map units were created by 

delineating habitats that contain at least 

one or more of the PCEs defined in 

paragraph (2) of this entry, over United 

States Geological Survey topographic 

maps (UTM 19, NAD 83). USGS 

1:20,000 quadrangles used in the base 

map were: Humacao, Punta Guayane ́s,
