Endangered and Threatened Wildlife and Plants; Designation of
Critical Habitat for Elfin-Woods Warbler
AGENCY: Fish and Wildlife Service, Interior.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We, the U.S. Fish and Wildlife Service (Service), designate
critical habitat for the elfin-woods warbler (Setophaga angelae) under
the Endangered Species Act of 1973, as amended (Act). In total,
approximately 27,488 acres (11,125 hectares) in the Maricao, San
Germ[aacute]n, Sabana Grande, Yauco, R[iacute]o Grande,
Can[oacute]vanas, Las Piedras, Naguabo, Ceiba, Cayey, San Lorenzo,
Guayama, and Patillas municipalities in Puerto Rico fall within the
boundaries of the critical habitat designation. The effect of this
regulation is to extend the Act's protections to the elfin-woods
warbler's critical habitat.
DATES: This rule is effective on July 30, 2020.
ADDRESSES: This final rule is available on the internet at http://www.regulations.gov under Docket No. FWS-R4-ES-2020-0030 and at http://www.fws.gov/caribbean. Comments and materials we received, as well as
some supporting documentation we used in preparing this rule, are
available for public inspection at http://www.regulations.gov under
Docket No. FWS-R4-ES-2020-0030.
The coordinates or plot points or both from which the maps are
generated are included in the administrative record for this critical
habitat designation and are available at http://www.regulations.gov at
Docket No. FWS-R4-ES-2020-0030 and at http://www.fws.gov/caribbean. Any
additional tools or supporting information that we developed for this
critical habitat designation will also be available at the Service
website and in the preamble at http://www.regulations.gov.

SUPPLEMENTARY INFORMATION:
Executive Summary
Why we need to publish a rule. Under the Act, if we determine that
any species is an endangered or threatened species, we must designate
critical habitat to the maximum extent prudent and determinable. We
published in the Federal Register a final rule to list the elfin-woods
warbler as a threatened species on June 22, 2016 (81 FR 40534). On that
same day, we also published a proposed rule to designate critical
habitat for the elfin-woods warbler (81 FR 40632). Designations of
critical habitat can only be completed by issuing a rule.
What this rule does. This rule will finalize the designation of
critical habitat for the elfin-woods warbler under the Act.
Accordingly, this rule revises part 17 of title 50 of the Code of
Federal Regulations at 50 CFR 17.95.
Basis for this rule. Under section 4(a)(3) of the Act, if we
determine that any species is an endangered or threatened species we
must, to the maximum extent prudent and determinable, designate
critical habitat. Section 4(b)(2) of the Act states that the Secretary
shall designate critical habitat 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. Section 3(5)(A) of the Act
defines critical habitat as (i) the specific areas within the
geographical area occupied by the species, at the time it is listed, on
which are found those physical or biological features (I) essential to
the conservation of the species and (II) which may require special
management considerations or protections; and (ii) specific areas
outside the geographical area occupied by the species at the time it is
listed, upon a determination by the Secretary that such areas are
essential
[[Page 39078]]
for the conservation of the species and that the area contains one or
more of those physical or biological features essential to the
conservation of the species, as interpreted by regulation at 50 CFR
424.12. 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.
The critical habitat we are designating in this rule, in three
units comprising 27,488 acres (ac) (11,125 hectares (ha)), constitutes
our current best assessment of the areas that meet the definition of
critical habitat for the elfin-woods warbler.
Economic analysis. In accordance with section 4(b)(2) of the Act,
we prepared an economic analysis of the impacts of designating critical
habitat. We published this announcement and solicited public comments
on the draft economic analysis (81 FR 40632; June 22, 2016).
Peer review and public comment. In accordance with our joint policy
on peer review published in the Federal Register on July 1, 1994 (59 FR
34270), and our August 22, 2016, memorandum updating and clarifying the
role of peer review of actions under the Act, we sought the expert
opinions of six independent specialists with scientific expertise that
included familiarity with the species, the geographic region in which
the species occurs, and conservation biology principles. The purpose of
peer review is to ensure that our designation is based on
scientifically sound data and analyses. We received responses from two
peer reviewers on our technical assumptions, analysis, and whether or
not we used the best scientific data available. These peer reviewers
generally concurred with our methods and conclusions and provided
additional information, clarifications, and suggestions to improve this
final rule. Information we received from peer review is incorporated in
this final designation of critical habitat. We also considered all
comments and information received from the public during the comment
period for the proposed designation of critical habitat.
Previous Federal Actions
All previous Federal actions are described in the proposed and
final listing rules for the elfin-woods warbler as a threatened species
under the Act published on September 30, 2015 (80 FR 58674) and June
22, 2016 (81 FR 40534). Concurrently with the final listing rule, we
adopted a rule under section 4(d) of the Act to provide for the
conservation of the elfin-woods warbler. We published our proposed rule
to designate critical habitat for the elfin-woods warbler on June 22,
2016 (81 FR 40632).
On August 27, 2019, we published a final rule in the Federal
Register (84 FR 45020) to amend our regulations concerning the
procedures and criteria we use to designate and revise critical
habitat. That rule became effective on September 26, 2019, but, as
stated in that rule, the amendments it sets forth apply to ``rules for
which a proposed rule was published after September 26, 2019.'' We
published our proposed critical habitat designation for the elfin-woods
warbler on June 22, 2016 (81 FR 40534); therefore, the amendments set
forth in the August 27, 2019, final rule at 84 FR 45020 do not apply to
this final designation of critical habitat for the elfin-woods warbler.
Nonetheless, we note that this designation is also consistent with the
standards set forth in the August 27, 2019 amendments to the
regulations.
Summary of Comments and Recommendations
In the June 22, 2016, proposed critical habitat rule (81 FR 40632),
we requested that all interested parties submit written comments on the
proposed designation of critical habitat for the elfin-woods warbler by
August 22, 2016. We also contacted appropriate Federal, State, and
local agencies, scientific organizations, and other interested parties
and invited them to comment on the proposed rule and draft economic
analysis (DEA). A newspaper notice inviting general public comment was
published in Primera Hora on June 24, 2016. We did not receive any
requests for a public hearing, and we did not receive any comments on
the DEA.
During the comment period, we received two comment letters from
peer reviewers directly addressing the proposed critical habitat
designation and one public comment. All substantive information
provided during the comment period has either been incorporated
directly into this final determination or addressed below, as
appropriate.
Peer Reviewer Comments
(1) Comment: A peer reviewer recommended adding the westernmost
patches of forest within the boundaries of the Maricao Commonwealth
Forest (MCF) as critical habitat for the elfin-woods warbler. According
to the reviewer, these forest patches qualify as essential habitat for
the conservation of the species for breeding, reproduction, or rearing
of offspring. The reviewer also reported two observations of elfin-
woods warbler in those patches.
Our Response: We reviewed the westernmost boundaries of Unit 1
(Maricao) of the proposed critical habitat and the new data documenting
the species' occurrence in the area. Based on the reanalysis of the
area and the data provided by the peer reviewer, we revised Unit 1 to
add approximately 363 ac (146 ha). This additional area comprises 2.8
percent of Unit 1. The Puerto Rico Department of Natural and
Environmental Resources (PDNER) manages 97.8 percent of the additional
area, in the MCF, with the remaining 2.2 percent (8 ac) of the
additional area on private land.
(2) Comment: A peer reviewer recommended we expand the Maricao Unit
because they believed habitat with physical and biological features on
private lands outside the western boundary of the MCF was left out of
the critical habitat designation. The reviewer recommended designating
active and abandoned shade-grown coffee plantations, agricultural lands
with native forest cover, and closed canopies that exist in the
mountainsides parallel to road PR#105 up to km 12.4, as critical
habitat. The reviewer stated that this area encompasses suitable
habitat consistently used and occupied by the elfin-woods warbler.
Our Response: We reanalyzed the lands adjacent to the western
boundary of the MCF. As described in our response to comment 1, we
identified an additional 8 ac (3.2 ha) of private land adjacent to the
MCF that is occupied and contains the physical and biological features
required by the elfin-woods warbler that we are including as critical
habitat. We determined the remainder of these private areas suggested
by the peer reviewer are disturbed and do not fit our established
criteria for critical habitat at this time (see Criteria Used To
Identify Critical Habitat). Because these areas are occupied, the
species is protected in these areas. For example, where a landowner
requests Federal agency funding or authorization for an action that may
affect a listed species or critical habitat, the Federal agency would
be required to consult with the Service under section 7(a)(2) of the
Act. Additionally, the prohibitions of section 9 of the Act apply to
the elfin-woods warblers that occur within these areas.
(3) Comment: A peer reviewer recommended we include Guilarte
Commonwealth Forest as another area outside the geographic range of the
[[Page 39079]]
elfin-woods warbler at the time of listing to be included as critical
habitat, based on the potential of this forest to provide connectivity
between occupied sites for genetic exchange and because it contains the
necessary habitat to support the species.
Our Response: Based on the best available information at this time,
we do not consider the Guilarte Commonwealth Forest (GCF) essential to
the conservation of the species. The elfin-woods warbler has never been
observed in the GCF, indicating the GCF may not be essential habitat
for the species. In addition, occupancy of resilient populations of the
elfin-woods warbler in the three areas that constitute its known
historical range, which we are designating as critical habitat, would
likely be sufficient to ensure conservation of the species. A critical
habitat designation does not signal that habitat outside the designated
area is unimportant or may not be beneficial for the recovery of the
species. The Service can develop recovery actions during recovery
planning for this site. We will continue working with our State
partners to address the conservation needs of the elfin-woods warbler.
Comments From States
Section 4(b)(5)(A)(ii) of the Act requires the Service to give
actual notice of any designation of lands that are considered to be
critical habitat to the appropriate agency of each State in which the
species is believed to occur, and invite each such agency to comment on
the proposed regulation. Section 4(i) of the Act states, ``the
Secretary shall submit to the State agency a written justification for
his failure to adopt regulations consistent with the agency's comments
or petition.'' For this rule we did not receive any written comments
from the Commonwealth of Puerto Rico.
Public Comments
We received one public comment on the proposed rule. While the
commenter indicated support for the habitat protection of the elfin-
woods warbler, the commenter did not provide substantive comments
requiring the Service's response.
Summary of Changes From Proposed Rule
This final rule incorporates changes to our proposed rule based on
the comments and information we received, as discussed above in the
Summary of Comments and Recommendations. All changes made were included
accordingly into the document, tables, and maps. As a result, the final
designation of critical habitat reflects the following changes from the
June 22, 2016, proposed rule (81 FR 40632):
1. We revised Unit 1 (Maricao) to include additional area as
critical habitat. This unit now consists of approximately 12,978 ac
(5,252 ha), which is an increase of approximately 2.8 percent of the
proposed area for Unit 1.
2. We corrected an error in the acreage of Unit 3 (Carite). The
error resulted from rounding of numbers (rounding up from 0.55), and
the change was an increase of approximately 1.1 ac (0.45 ha).
3. We refined our description of the physical and biological
features to be more explicit about the features we are identifying,
specifying these features include elevations above 300 meters in active
shade-grown coffee plantations or forested agricultural lands dominated
primarily by native vegetation, or abandoned coffee plantations or
agricultural lands with native forest cover and a closed canopy. In the
proposed rule, we did not specify the elevations in these landscapes.
No adjustments to the unit boundaries were needed as a result of this
change.
4. We updated the coordinates or plot points from which the maps
were generated. The information is available at http://www.regulations.gov under Docket No. FWS-R4-ES-2020-0030, and from the
Caribbean Ecological Services Field Office website at http://www.fws.gov/caribbean.
Critical Habitat
Background
Critical habitat is defined in section 3 of the Act as:
(1) The specific areas within the geographical area occupied by the
species, at the time it is listed in accordance with the Act, on which
are found those physical or biological features
(a) Essential to the conservation of the species, and
(b) Which may require special management considerations or
protection; and
(2) Specific areas outside the geographical area occupied by the
species at the time it is listed, upon a determination that such areas
are essential for the conservation of the species.
Our regulations at 50 CFR 424.02 define the geographical area
occupied by the species as: An area that may generally be delineated
around species' occurrences, as determined by the Secretary (i.e.,
range). Such areas may include those areas used throughout all or part
of the species' life cycle, even if not used on a regular basis (e.g.,
migratory corridors, seasonal habitats, and habitats used periodically,
but not solely by vagrant individuals).
Conservation, as defined under section 3 of the Act, means to use
and the use of all methods and procedures that are necessary to bring
an endangered or threatened species to the point at which the measures
provided pursuant to the Act are no longer necessary. Such methods and
procedures include, but are not limited to, all activities associated
with scientific resources management such as research, census, law
enforcement, habitat acquisition and maintenance, propagation, live
trapping, and transplantation, and, in the extraordinary case where
population pressures within a given ecosystem cannot be otherwise
relieved, may include regulated taking.
Critical habitat receives protection under section 7 of the Act
through the requirement that Federal agencies ensure, in consultation
with the Service, that any action they authorize, fund, or carry out is
not 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 the government
or public to access private lands. Such designation does not require
implementation of restoration, recovery, or enhancement measures by
non-Federal landowners. Where a landowner requests Federal agency
funding or authorization for an action that may affect a listed species
or critical habitat, the Federal agency would be required to consult
with the Service under section 7(a)(2) of the Act. However, even if the
Service were to conclude that the proposed activity would result in
destruction or adverse modification of the critical habitat, the
Federal action agency and the landowner are not required to abandon the
proposed activity, or to restore or recover the species; instead, they
must implement ``reasonable and prudent alternatives'' to avoid
destruction or adverse modification of critical habitat.
Under the first prong of the Act's definition of critical habitat,
areas within the geographical area occupied by the species at the time
it was listed are included in a critical habitat designation if they
contain physical or biological features (1) which are essential to the
conservation of the species and (2) which may require special
management considerations or protection. For these areas, critical
[[Page 39080]]
habitat designations identify, to the extent known using the best
scientific and commercial data available, those physical or biological
features that are essential to the conservation of the species (such as
space, food, cover, and protected habitat). In identifying those
physical or biological features within an area, we focus on the
specific features that support the life-history needs of the species,
including but not limited to, water characteristics, soil type,
geological features, prey, vegetation, symbiotic species, or other
features. A feature may be a single habitat characteristic, or a more
complex combination of habitat characteristics. Features may include
habitat characteristics that support ephemeral or dynamic habitat
conditions. Features may also be expressed in terms relating to
principles of conservation biology, such as patch size, distribution
distances, and connectivity.
Under the second prong of the Act's definition of critical habitat,
we may designate critical habitat in areas outside the geographical
area occupied by the species at the time it is listed, upon a
determination that such areas are essential for the conservation of the
species.
For the elfin-woods warbler, we determined whether unoccupied areas
are essential for the conservation of the species by considering the
life-history, status, and conservation needs of the species. Our
decision was further informed by observations of species-habitat
relationships, habitat suitability models derived from these
observations, and the locations of historical records to identify which
features and specific areas are essential to the conservation of the
species and, as a result, the development of the critical habitat
designation.
Section 4 of the Act requires that we designate critical habitat on
the basis of the best scientific data available. Further, our Policy on
Information Standards Under the Endangered Species Act (published in
the Federal Register on July 1, 1994 (59 FR 34271)), the Information
Quality Act (section 515 of the Treasury and General Government
Appropriations Act for Fiscal Year 2001 (Pub. L. 106-554; H.R. 5658)),
and our associated Information Quality Guidelines provide criteria,
establish procedures, and provide guidance to ensure that our decisions
are based on the best scientific data available. They require our
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 we are determining which areas should be designated as
critical habitat, our primary source of information is generally the
information developed during the listing process for the species.
Additional information sources may include any generalized conservation
strategy, criteria, or outline that may have been developed for the
species, 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, other
unpublished materials, or experts' opinions or personal knowledge.
Habitat is dynamic, and species may move from one area to another
over time. We recognize that critical habitat designated at a
particular point in time may not include all of the habitat areas that
we may later determine are necessary for the recovery of the species.
For these reasons, a critical habitat designation does not signal that
habitat outside the designated area is unimportant or may not be needed
for recovery of the species. Areas that are important to the
conservation of the species, both inside and outside the critical
habitat designation, will continue to be subject to: (1) Conservation
actions implemented under section 7(a)(1) of the Act, (2) regulatory
protections afforded by the requirement in section 7(a)(2) of the Act
for Federal agencies to ensure their actions are not likely to
jeopardize the continued existence of any endangered or threatened
species, and (3) section 9 of the Act's prohibitions on taking any
individual of the species, including taking caused by actions that
affect habitat. Federally funded or permitted projects affecting listed
species outside their designated critical habitat areas may still
result in jeopardy findings in some cases. These protections and
conservation tools will continue to contribute to recovery of this
species. 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 (HCPs), or other species conservation planning
efforts if new information available at the time of these planning
efforts calls for a different outcome.
Physical or Biological Features Essential to the Conservation of the
Species
In accordance with section 3(5)(A)(i) of the Act and regulations at
50 CFR 424.12(b), in determining which areas within the geographical
area occupied by the species at the time of listing to designate as
critical habitat, we consider the physical or biological features
(PBFs) that are essential to the conservation of the species and which
may require special management considerations or protection. For
example, physical features might include gravel of a particular size
required for spawning, alkali soil for seed germination, protective
cover for migration, or susceptibility to flooding or fire that
maintains necessary early-successional habitat characteristics.
Biological features might include prey species, forage grasses,
specific kinds or ages of trees for roosting or nesting, symbiotic
fungi, or a particular level of nonnative species consistent with
conservation needs of the listed species. The features may also be
combinations of habitat characteristics and may encompass the
relationship between characteristics or the necessary amount of a
characteristic needed to support the life history of the species. In
considering whether features are essential to the conservation of the
species, the Service may consider an appropriate quality, quantity, and
spatial and temporal arrangement of habitat characteristics in the
context of the life-history needs, condition, and status of the
species. These characteristics 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, or
rearing (or development) of offspring; and habitats that are protected
from disturbance.
The elfin-woods warbler is an endemic Puerto Rican bird with a very
limited distribution. It is typically observed in forested habitats
with closed canopy and well-developed understory in higher elevations.
Based on the best available information, there are only two known
elfin-woods warbler populations, one each in eastern and western Puerto
Rico.
The eastern population occurs at El Yunque National Forest (EYNF)
located within the Sierra de Luquillo mountains. The species' primary
habitat in EYNF consists of the dwarf forest (Kepler and Parkes 1972,
pp. 3-5) and the Palo Colorado forest (Wiley and Bauer 1985, pp. 12-
18). The dwarf forest falls within the lower montane rain forest life
zone (Ewel and Whitmore 1973, p. 49). It is found on exposed peaks with
short, stunted vegetation above 900 meters (m) (2,952 feet (ft)) in
elevation (Weaver 2012, p. 58). The
[[Page 39081]]
dwarf forest is characterized by a single story of trees that range
from 1 to 6 m (3 to 19 ft) in height, depending on exposure (Weaver
2012, p. 58). However, trees located on rocky summits are limited to 2
to 3 m (6 to 10 ft) in height. Although no tree species is confined to
this type of forest, only a few species, such as Podocarpus coriaceus
(no common name, referred to as ``Podocarpus''), Ocotea spathulata
(nemoc[aacute]), and Ilex sintenisii (no common name), are adapted to
survive on the exposed summits of this forest (Weaver 2012, p. 58). The
dwarf forest is also characterized by the abundance of mosses,
epiphytes, and liverworts that cover the majority of the forest surface
(Lugo 2005, p. 514).
The Palo Colorado forest occurs on gentle slopes within the lower
montane wet and lower montane rain forest life zones, approximately
between 600 and 900 m (1,968 and 2,952 ft) in elevation (Weaver 2012,
p. 1; U.S. Forest Service (USFS) no date). This forest type mainly
consists of fast-growing trees with heights not exceeding more than 24
m (78 ft) (Lugo 2005, p. 506). This forest type is essentially an
upland swamp of short-statured trees with shallow root systems (USFS,
no date). Some of the most common tree species are Cyrilla racemiflora
(Palo Colorado), Prestoea montana (Sierra palm), Ocotea spathulata, and
Croton poecilanthus (sabin[oacute]n) (Weaver 2012, p. 55). The
understory of the Palo Colorado forest is dominated by grasses,
bromeliads, ferns, and sedges (Lugo 2005, p. 508).
The western population of the elfin-woods warbler is located within
the MCF and adjacent agricultural lands. The MCF is located within the
Cordillera Central (central mountain range) of Puerto Rico. The primary
habitat of the western population consists of Podocarpus forest,
exposed ridge woodland, and timber plantation forests (Gonz[aacute]lez
2008, pp. 15-16). The Podocarpus forest is located on the slopes and
highest peaks (600 to 900 m (1,968 to 2,952 ft)) within the lower
montane wet forest life zone (DNR 1976, p. 185; Ewel and Whitmore 1973,
p. 41). At the MCF, this type of forest grows on deep serpentine soils
and is dominated by Podocarpus coriaceus trees; a continuous closed
canopy of approximately 20 m (66 ft) of height; and a well-developed
understory composed of tree ferns (Cyathea spp.), Sierra palm, and
vines (Tossas and Delannoy 2001, pp. 47-53; Anad[oacute]n-Irizarry
2006, p. 53; Gonz[aacute]lez 2008, pp. 15-16). The exposed ridge
woodland forest is found in valleys, slopes, and shallow soils with a
more or less continuous canopy (Gonz[aacute]lez 2008, pp. 15-16). These
forest associations are found at elevations ranging from 550 to 750 m
(1,804 to 2,460 ft) within the subtropical wet forest life zone (DNR
1976, p. 185; Ricart-Pujals and Padr[oacute]n-V[eacute]lez 2010, p. 9).
The timber plantation forest is found in elevations ranging from 630 to
850 m (2,066 to 2,788 ft) within the subtropical wet forest and the
subtropical moist forest life zones (DNR 1976, p. 185). Habitat in this
forest is predominantly Calophyllum calaba (Mar[iacute]a trees),
Eucalyptus robusta (eucalyptus), and Pinus caribaea (Honduran pine)
planted in areas that were deforested for agriculture (Delannoy 2007,
p. 9; Gonz[aacute]lez 2008, p. 5).
In the privately owned lands adjacent to the MCF, the species has
been reported mainly within secondary forests (both young and mature
secondary forests) and shade-grown coffee plantations (Gonz[aacute]lez
2008, pp. 15-16). The young secondary forests are less than 25 years
old with a mostly open canopy approximately 12 to 15 m (40 to 50 ft) in
height (Gonz[aacute]lez 2008, p. 6). These forests are found within the
subtropical moist and subtropical wet forest life zones at elevations
ranging from 300 to 750 m (984 to 2,460 ft) (Gonz[aacute]lez 2008, p.
59; Puerto Rico Planning Board 2015, no page number), and cover
approximately 98 percent of the MCF (DNR 1976, p. 185). The understory
is well developed and dominated by grasses, vines, and other early
successional species (Gonz[aacute]lez 2008, p. 6). Mature secondary
forests are over 25 years old, developing in humid and very humid,
moderate to steep slopes. These forests are characterized by a closed
canopy of approximately 20 to 30 m (66 to 100 ft) in height and sparse
to abundant understory (Gonz[aacute]lez 2008, p. 6). The shade-grown
coffee plantations are covered with tall mature trees, dominated mostly
by Inga vera (guaba), Inga laurina (guam[aacute]), Andira inermis
(moca), and Guarea guidonia (guaraguao) trees, reaching 15 to 20 m (50
to 66 ft) in height, with an open understory without grasses
(Gonz[aacute]lez 2008, p. 6). Located adjacent to the MCF at elevations
between 300 and 600 m (984 and 1,968 ft), these shade-grown coffee
plantations extend the vegetation cover and provide habitat for the
species (Gonz[aacute]lez 2008, p. 59).
According to the habitat suitability model developed for the
species, all the habitats described above occur within the intermediate
to very high adequacy category (Col[oacute]n-Merced 2013, p. 57). This
model is based on a combination of elevation and vegetation cover in
areas where the species is known to occur. In addition, the species
appears to be associated with high elevations and is seldom observed in
elevations lower than 300 m (984 ft). The habitat types identified
above are the only habitats that the species is known to occupy and use
for normal behavior that support its life-history processes. Thus,
protection and maintenance of these forested habitat features are
essential for rearing, growth, foraging, migration, and other normal
behaviors of the species.
Limited information is available concerning the elfin-woods
warbler's breeding, reproduction, and offspring development. However,
based on the best available information, shaded and forested corridors
are features that are essential to breeding, reproduction, and rearing.
The elfin-woods warbler's breeding occurs between March and June
(Raffaele et al. 1998, p. 406). Clutch size is usually two to three
eggs, but there have been observations of nests that contain broods of
up to four nestlings (Raffaele et al. 1998, p. 406; Rodr[iacute]guez-
Mojica 2004, p. 22). The species' nest is described as a compact cup,
usually close to the trunk and well hidden among epiphytes of small
trees (Raffaele et al. 1998, p. 406). The first elfin-woods warbler
nest was found in 1985 at EYNF (Arroyo-V[aacute]zquez 1992, p. 362),
and later, two nests were found in the MCF area (Arryo-V[aacute]zquez
1992, p. 362). Both nests in the MCF were in Podocarpus forest, placed
in trees among dry leaf litter trapped in vegetation or vines at
heights between 1.3 and 7.6 m (4.3 and 25.0 ft) (Arroyo-V[aacute]zquez
1992, pp. 362-364). In 2004, the first nesting event in a cavity of a
rotten Cyrilla racemiflora stump in the MCF area was reported
(Rodr[iacute]guez-Mojica 2004, p. 22). The nest was placed about 7 m
(23 ft) above ground and 6 centimeters (cm) (2 inches (in)) deep from
the lower border of the irregular rim of the stump. No other warbler
species in Puerto Rico have been reported using such a nesting site
(Rodr[iacute]guez-Mojica 2004, p. 23).
Based on the available information describing the habitat used by
the elfin-woods warbler, we identified the dwarf, Palo Colorado,
Podocarpus, exposed ridge woodland, and timber plantation forests and
forest associations (shaded and forested corridors); secondary forests;
and shade-grown coffee plantations. These habitats contain physical or
biological features that are essential to the conservation of the
elfin-woods warbler because they provide space for population growth
and normal behavior; cover and shelter; and sites for breeding,
rearing, and development of offspring.
[[Page 39082]]
Summary of Essential Physical or Biological Features
We derived the specific physical or biological features (PBFs)
essential to the conservation of the elfin-woods warbler from studies
of this species' habitat, ecology, and life history as described above.
Additional information can be found in the final listing rule published
in the Federal Register on June 22, 2016 (81 FR 45035), and in our
proposed critical habitat designation, which also published in the
Federal Register on June 22, 2016 (81 FR 40632). We have determined
that the following PBFs are essential to the conservation of elfin-
woods warbler:
1. Wet and rain montane forest types:
a. Podocarpus forest at elevations between 600 and 900 m (1,968 and
2,952 ft) with continuous closed canopy of 20 m (66 ft) in height,
dominated by Podocarpus coriaceus trees with well-developed understory.
b. Dwarf forest at elevations above 900 m (2,952 ft) with a single
story of trees between 1 and 6 m (3 and 19 ft) in height, with an
understory of mosses, epiphytes, and liverworts.
c. Palo Colorado forest at elevations between 600 and 900 m (1,968
and 2,952 ft) with a closed canopy of approximately 20 m (66 ft) and an
understory dominated by grasses, ferns, bromeliads, and sedges.
2. Forested habitat areas that contain:
a. Active shade-grown coffee plantations or forested agricultural
lands that are above 300 m in elevation and are dominated primarily by
native vegetation; or
b. Abandoned coffee plantations or agricultural lands (i.e.,
agricultural practices were discontinued) with native forest cover and
a closed canopy found above 300 m in elevation.
3. Forested habitat (at elevations between 300 and 850 m (984 and
2,788 ft)) not contained within the habitats described in PBF 1 or PBF
2:
a. Exposed ridge woodland forest found in valleys, slopes, and
shallow soils with a more or less continuous canopy at elevations
ranging from 550 to 750 m (1,804 to 2,460 ft);
b. Timber plantation forest at elevations ranging from 630 to 850 m
(2,066 to 2,788 ft); or
c. Secondary forests dominated by native tree species with a closed
canopy of approximately 20-30 m (66-100 ft) in height at elevations
ranging from 300 to 750 m (984 to 2,460 ft).
Special Management Considerations or Protection
When designating critical habitat, we assess whether the specific
areas within the geographical area occupied by the species at the time
of listing contain features that are essential to the conservation of
the species and may require special management considerations or
protection.
The Maricao unit contains privately owned agricultural lands in
which various activities may affect one or more of the PBFs. The
features of this unit essential to the conservation of the elfin-woods
warbler may require special management considerations or protection to
reduce the following threats: Loss, fragmentation, and degradation of
habitat due to unsustainable agricultural practices; hurricanes; and
human-induced fires. The features of the El Yunque unit may require
special management considerations or protection to reduce threats or
potential threats from hurricanes and human-induced fires, which may be
exacerbated by the effects of climate change.
Management activities that could ameliorate these threats or
potential threats include but are not limited to the following: The
2014 candidate conservation agreement (CCA) signed by the Service, U.S.
Forest Service, and Puerto Rico Department of Natural and Environmental
Resources (PRDNER) to implement conservation practices for the benefit
of the elfin-woods warbler and its habitat in EYNF and MCF (USFWS
2014); implementation of conservation agreements with private
landowners to restore habitat and minimize habitat disturbance and
fragmentation; and development and implementation of management plans
for other protected lands where the species is found.
Criteria Used To Identify Critical Habitat
As required by section 4(b)(2) of the Act, we use the best
scientific data available to designate critical habitat. In accordance
with the Act and our implementing regulations at 50 CFR 424.12(b), we
review available information pertaining to the habitat requirements of
the species and identify specific areas within the geographical area
occupied by the species at the time of listing and any specific areas
outside the geographical area occupied by the species to be considered
for designation as critical habitat.
Because of the vulnerability associated with small populations,
limited distributions, or both (as described in the final listing
rule), conservation of the elfin-woods warbler requires protection of
both existing occupied habitat and potential habitat (i.e., suitable
for occupancy but currently unoccupied), and the establishment of new
populations to reduce or eliminate such vulnerability. In this case, we
considered potential habitat to be historically occupied areas that
currently possess the PBFs suitable for elfin-woods warbler
recolonization and subsequent persistence. Therefore, for the elfin-
woods warbler, in addition to areas occupied by the species at the time
of listing, we are designating habitat outside the geographical area
occupied by the species at the time of listing (Unit 3, Carite), which
was historically occupied but is presently unoccupied, because it is
essential for the conservation of the species and that the area
contains one or more of those physical or biological features essential
to the conservation of the species.
Sources of data for this critical habitat designation include
reports on assessments and surveys throughout the species' range, peer-
reviewed scientific and academic literature, habitat suitability
models, personal communications with the species experts (e.g.,
Col[oacute]n-Merced 2013; Gonz[aacute]lez 2008; Anad[oacute]n-Irizarry
2006; Delannoy 2007; Arroyo-V[aacute]zquez 1992; P[eacute]rez-Rivera
2014, pers. comm.); and information from Service biologists. Other
sources include databases maintained by Commonwealth and Federal
agencies regarding Puerto Rico (such as elevation data, land cover
data, aerial imagery, protected areas, and U.S. Geological Survey
(USGS) topographic maps). Critical habitat units were then mapped using
ArcMap version 10 (Environmental Systems Research Institute, Inc.), a
geographic information system (GIS) program.
To further refine the critical habitat boundaries, we used an
existing elfin-woods warbler habitat suitability model (Col[oacute]n-
Merced 2013, p. 51). This model uses variables such as elevation and
vegetation cover to predict suitable habitat for this species in Puerto
Rico (Col[oacute]n-Merced 2013, p. 45). This model has been validated
in several locations in Puerto Rico (Anad[oacute]n-Irizarry 2017, pp.
7-10; Anad[oacute]n-Irizarry et al. 2017, entire).
In order to identify essential features within private lands
adjacent to the MCF, we established a buffer zone of 500 m (0.31 mile
(mi)) from the boundary line of the MCF to include forested areas in
abandoned and active shade-grown coffee plantations where the elfin-
woods warbler has been reported on the north, east, and west sides of
the forest (Gonz[aacute]lez 2008, p. 59). We used 500 m (0.31 mi) as
our buffer zone, because our best understanding of the available
information (e.g., spatial data and on-
[[Page 39083]]
the-ground data) is that this area encompasses suitable habitat that
supports the conservation of the elfin-woods warbler.
Areas Occupied at the Time of Listing
The final critical habitat designation focuses on occupied forested
areas within the species' historical range containing the PBFs that
will allow for the maintenance and expansion of existing populations
and for possible new populations. Two locations meet the definition of
geographic areas occupied by the species at the time of listing: (1)
EYNF, and (2) MCF and adjacent private lands to the north, east, and
west.
Areas Outside the Geographical Area Occupied at the Time of Listing
To consider for designation areas not occupied by the species at
the time of the listing, we must demonstrate that these areas are
essential for the conservation of the species and that the area
contains one or more of those physical or biological features essential
to the conservation of the species. To determine if these areas are
essential for the conservation of the elfin-woods warbler, we
considered the life history, status, habitat elements, and conservation
needs of the species such as:
(1) The importance of the area to the overall status of the species
to prevent extinction and contribute to the species' conservation;
(2) Whether the area contains the necessary habitat to support the
species;
(3) Whether the area provides connectivity between occupied sites
for genetic exchange; and
(4) Whether a population of the species could be reestablished in
the area.
The Carite Commonwealth Forest (CCF) is within the historical range
of the elfin-woods warbler, within the Sierra de Cayey mountains in
southeast Puerto Rico (Silander et al. 1986, p. 178); the Sierra de
Cayey mountains are connected to the Cordillera Central mountains,
which extend from Aibonito in the east to Maricao in the west of Puerto
Rico (Monroe 1980, p. 16). However, the species has not been reported
in CCF since 2000 (Anad[oacute]n-Irizarry 2006, p. 34; P[eacute]rez-
Rivera 2014, pers. comm.; Aide and Campos 2016, entire).
The CCF has been managed for conservation by the PRDNER since 1975
(previously Department of Natural Resources (DNR); DNR 1976, p. 169).
This forest covers about 6,660 ac (2,695 ha), and ranges between 820
and 2,962 ft (250 and 903 m) in elevation (DNR 1976, p. 168). The mean
annual precipitation is 225 cm (88.5 in), and the mean temperature is
72.3 degrees Fahrenheit ([deg]F) (22.7 degrees Celsius ([deg]C)) (DNR
1976, p. 169; Silander et al. 1986, p. 183).
The CCF contains the following forest types, which contain the PBFs
for the elfin-woods warbler: Dwarf forest, Palo Colorado forest, timber
plantation forest, and secondary forests. These are the same forest
types used by the elfin-woods warbler in EYNF and MCF and are located
within the same life zones in CCF as they are in EYNF and MCF (Ewel and
Whitmore 1973, p. 74).
Although studies conducted by Anad[oacute]n-Irizarry (2006, 2014)
between 2003-2004 and 2012-2013 failed to detect the species within the
CCF, she suggested the possibility that the species may still be
present in isolated pockets of forest that were not searched during
those studies. The elfin-woods warbler may be difficult to detect owing
to its persistent and relatively sedentary behavior and because it has
an affinity for certain small and isolated pockets of forest
(Anad[oacute]n-Irizarry 2006, p. 54; Delannoy 2007, pp. 22-23;
P[eacute]rez-Rivera 2014, pers. comm.). However, surveys contracted by
the Service and conducted between March and April 2016 did not detect
the species within the CCF and adjacent private lands (Aide and Campos
2016, entire). In any case, the CCF contains habitat that is likely
suitable for the elfin-woods warbler due to its similarity in
elevation, climatic conditions, and vegetation associations with EYNF
and MCF (Col[oacute]n-Merced 2013, p. 57). This area contains habitat
with ``intermediate to very high adequacy'' (favorable to optimal
combination of elevation and vegetation cover in the known elfin-woods
warbler habitat) according to the habitat suitability model for the
species (Col[oacute]n-Merced 2013, p. 57).
The CCF provides the necessary habitat to support the elfin-woods
warbler in the easternmost part of the Cordillera Central. The presence
of suitable habitat characteristics and historic occurrence of the
species within the CCF increases the opportunity for future
reestablishment of a population of elfin-woods warblers in this forest.
In addition, the connectivity between MCF and CCF through the
Cordillera Central is expected to result in genetic exchange between
the existing MCF populations and CCF populations that may be
reestablished in the future. While there is connectivity between MCF
and CCF, the EYNF is within the Sierra de Luquillo mountains with lower
elevation and development between the mountain ranges that
significantly reduces connectivity between CCF and EYNF. For the above-
mentioned reasons, we conclude that suitable habitat within the CCF
meets the four considerations described above, and is therefore
essential for the conservation of the elfin-woods warbler.
General Information on the Maps of the Critical Habitat Designation
When determining critical habitat boundaries within this final
rule, we made every effort to avoid including developed areas such as
lands covered by buildings, pavement, and other structures because such
lands lack physical or biological features necessary for elfin-woods
warbler. The scale of the maps we prepared under the parameters for
publication within the Code of Federal Regulations may not reflect the
exclusion of such developed lands. Any such lands inadvertently left
inside critical habitat boundaries shown on the maps of this final rule
have been excluded by text in the rule and are not designated as
critical habitat. Therefore, a Federal action involving these lands
will not trigger section 7 consultation with respect to critical
habitat and the requirement of no adverse modification unless the
specific action would affect the physical or biological features in the
adjacent critical habitat.
We are designating as critical habitat in areas that we have
determined were occupied at the time of listing in 2016 and contain
physical or biological features to support life-history processes
essential to the conservation of the species. We are also designating
specific areas within one unit outside of the geographical area
occupied by the species at the time of listing, which were historically
occupied but are presently unoccupied, because we have determined that
such areas are essential for the conservation of elfin-woods warbler
and that the area contains one or more of those physical or biological
features essential to the conservation of the warbler.
All units were designated based on one or more of the elements of
physical or biological features being present to support elfin-woods
warbler's life processes. Some units contained all of the identified
elements of physical or biological features and supported multiple life
processes. Some units contained only some elements of the physical or
biological features necessary to support the elfin-woods warbler's
particular use of that habitat.
The critical habitat designation is defined by the map or maps, as
modified by any accompanying regulatory text, presented at the end of
this document under Regulation
[[Page 39084]]
Promulgation. We include more detailed information on the boundaries of
the critical habitat designation in the discussion of individual units
below. We will make the coordinates or plot points or both on which
each map is based available to the public on http://www.regulations.gov
under Docket No. FWS-R4-ES-2020-0030 and at http://www.fws.gov/caribbean.
Final Critical Habitat Designation
We are designating approximately 27,488 acres (11,125 hectares) in
three units as critical habitat for elfin-woods warbler. The critical
habitat areas described below constitute our best assessment of areas
that meet the definition of critical habitat for the elfin-woods
warbler. Those three units are: (1) Maricao, (2) El Yunque, and (3)
Carite. Table 1 shows the name, occupancy of the unit, municipality,
land ownership, and approximate area of the designated critical habitat
units for the elfin-woods warbler.

--------------------------------------------------------------------------------------------------------------------------------------------------------
Note: Area sizes may not sum due to rounding.
We present brief descriptions of all units, and reasons why they
meet the definition of critical habitat for elfin-woods warbler, below.
Unit 1: Maricao
Unit 1 consists of 12,978 ac (5,252 ha). Approximately 8,861 ac
(3,586 ha) are owned by the Commonwealth and managed by the PRDNER, and
4,117 ac (1,666 ha) are in private ownership. This unit is located
within the municipalities of Maricao, San Germ[aacute]n, Sabana Grande,
and Yauco and encompasses the majority of the Maricao Commonwealth
Forest. The unit is located north of State Road PR-2, south of State
Road PR-105, and approximately 65 miles (mi) (105 kilometers (km)) west
of the International Airport Luis Mu[ntilde]oz Marin. This unit is
within the geographical area occupied by the elfin-woods warbler at the
time of listing. This unit contains all the PBFs and a core population
of the species, and will likely contribute to range expansion of the
elfin-woods warbler by serving as a source of birds to found elfin-
woods warbler populations in Carite, which is currently unoccupied but
contains the PBFs.
The PBFs in this unit may require special considerations or
protection to address the following threats or potential threats that
may result in changes in the composition or abundance of vegetation
within this unit: Loss, fragmentation, and degradation of habitat due
to unsustainable agricultural practices; hurricanes; and human-induced
fires.
Unit 2: El Yunque
Unit 2 consists of 11,430 ac (4,626 ha) of federally owned land
managed by the U.S. Forest Service (EYNF). It is located within the
municipalities of R[iacute]o Grande, Canovanas, Las Piedras, Naguabo,
and Ceiba. The unit is located east of State Road PR-186, north of
State Road PR-31, and approximately 15 mi (24 km) east of the
International Airport Luis Mu[ntilde]oz Marin. This unit is within the
geographical area occupied by the elfin-woods warbler at the time of
listing and contains PBFs 1(b) and 1(c) (see Physical or Biological
Features Essential to the Conservation of the Species, above). This
unit represents a core population of the species and helps to maintain
the elfin-woods warbler's geographical range.
The PBFs in this unit may require special considerations or
protection to reduce threats or potential threats from hurricanes and
human-induced fires, which may be exacerbated by the effects of climate
change.
Unit 3: Carite
Unit 3 consists of 3,080 ac (1,247 ha) of lands owned by the
Commonwealth and managed by the PRDNER. It is located within the
municipalities of Cayey, San Lorenzo, Guayama, and Patillas. The unit
is located within the CCF west of State Road PR-7740 and State Road PR-
184 that runs within the CCF, and approximately 23 mi (37 km) south of
the International Airport Luis Mu[ntilde]oz Marin. This unit was not
occupied by the elfin-woods warbler at the time of listing and is
considered to be essential for the conservation of the species. As
discussed above (see Criteria Used to Identify Critical Habitat), this
unit currently has the habitat features, including all of the PBFs, to
support the elfin-woods warbler. Therefore, this unit provides an
opportunity for expansion of the species' documented current range into
an area that was previously occupied; this potential expansion will
help to increase the redundancy and resiliency of the species.
Therefore, we conclude that this unit is essential for the conservation
of the elfin-woods warbler.
Effects of Critical Habitat Designation
Section 7 Consultation
Section 7(a)(2) of the Act requires Federal agencies, including the
Service, to ensure that any action they fund, authorize, or carry out
is not likely to jeopardize the continued existence of any endangered
species or threatened species or result in the destruction or adverse
modification of designated critical habitat of such species. In
addition, section 7(a)(4) of the Act requires Federal agencies to
confer with the Service on any agency action which is likely to
jeopardize the continued existence of any species proposed to be listed
under the Act or result in the destruction or adverse modification of
proposed critical habitat.
We published a final regulation with a revised definition of
destruction or adverse modification on August 27, 2019 (84 FR 44976).
Destruction or adverse modification means a direct or indirect
alteration that appreciably diminishes the value of critical habitat
[[Page 39085]]
as a whole for the conservation of a listed species.
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. Examples of actions that are subject to the
section 7 consultation process are actions on State, tribal, local, or
private lands that require a Federal permit (such as a permit from the
U.S. Army Corps of Engineers under section 404 of the Clean Water Act
(33 U.S.C. 1251 et seq.) or a permit from the Service under section 10
of the Act) or that involve some other Federal action (such as funding
from the Federal Highway Administration, Federal Aviation
Administration, or the Federal Emergency Management Agency). 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 carried out by a Federal agency--do not require
section 7 consultation.
Compliance with the requirements of section 7(a)(2) is documented
through our 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 and
are likely to adversely affect, listed species or critical habitat.
When we issue a biological opinion concluding that a project is
likely to jeopardize the continued existence of a listed species and/or
destroy or adversely modify critical habitat, we provide reasonable and
prudent alternatives to the project, if any are identifiable, that
would avoid the likelihood of jeopardy and/or destruction or adverse
modification of critical habitat. We define ``reasonable and prudent
alternatives'' (at 50 CFR 402.02) as alternative actions identified
during consultation that:
(1) Can be implemented in a manner consistent with the intended
purpose of the action,
(2) Can be implemented consistent with the scope of the Federal
agency's legal authority and jurisdiction,
(3) Are economically and technologically feasible, and
(4) Would, in the Director's opinion, avoid the likelihood of
jeopardizing the continued existence of the listed species and/or avoid
the likelihood of destroying or adversely modifying 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 set forth requirements for Federal
agencies to reinitiate formal consultation on previously reviewed
actions. These requirements apply when the Federal agency has retained
discretionary involvement or control over the action (or the agency's
discretionary involvement or control is authorized by law) and,
subsequent to the previous consultation, we have listed a new species
or designated critical habitat that may be affected by the Federal
action, or the action has been modified in a manner that affects the
species or critical habitat in a way not considered in the previous
consultation. In such situations, Federal agencies sometimes may need
to request reinitiation of consultation with us, but the regulations
also specify some exceptions to the requirement to reinitiate
consultation on specific land management plans after subsequently
listing a new species or designating new critical habitat. See the
regulations for a description of those exceptions.
Application of the ``Destruction or Adverse Modification'' Standard
The key factor related to the destruction or adverse modification
determination is whether implementation of the proposed Federal action
directly or indirectly alters the designated critical habitat in a way
that appreciably diminishes the value of the critical habitat as a
whole for the conservation of the listed species. As discussed above,
the role of critical habitat is to support physical or biological
features essential to the conservation of a listed species and provide
for the conservation of the species.
Section 4(b)(8) of the Act requires us to briefly evaluate and
describe, in any proposed or final regulation that designates critical
habitat, activities involving a Federal action that may violate section
7(a)(2) of the Act by destroying or adversely modifying such habitat,
or that may be affected by such designation.
Activities that the Services may, during a consultation under
section 7(a)(2) of the Act, find are likely to destroy or adversely
modify critical habitat include, but are not limited to:
(1) Actions that would significantly alter the structure and
function of active shade-grown coffee plantations, abandoned coffee
plantations, and/or agricultural lands with native forest cover and a
closed canopy. These actions or activities may include, but are not
limited to, deforestation, conversion of shade-grown coffee to sun-
grown coffee plantations, and unsustainable agricultural practices
(i.e., agricultural and silvicultural practices other than sun-to-
shade-grown coffee conversion, and herbicide and pesticide use outside
coffee plantations). These actions could degrade the habitat used by
the elfin-woods warbler for feeding, reproducing, and sheltering.
(2) Actions that would significantly alter the vegetation structure
in and around the Podocarpus, dwarf, or Palo Colorado forests and
forest associations. These actions or activities may include, but are
not limited to, habitat modification (e.g., deforestation,
fragmentation, loss, introduction of nonnative species, expansion or
construction of communication facilities, expansion of recreational
facilities, pipeline construction, bridge construction, road
rehabilitation and maintenance, habitat management), Federal and State
trust species reintroductions, trail maintenance, camping area
maintenance, research, repair and restoration of landslides, and any
other activities that are not conducted in accordance with the
consultation and planning requirements for listed species under section
7 of the Act. These activities could alter the habitat structure
essential to the elfin-woods warbler and may create suitable conditions
for other species that compete with or prey upon the elfin-woods
warbler or displace the species from its habitat.
Exemptions
Application of Section 4(a)(3) of the Act
Section 4(a)(3)(B)(i) of the Act (16 U.S.C. 1533(a)(3)(B)(i))
provides that: ``The Secretary shall not designate as critical habitat
any lands or other geographical areas owned or controlled by the
Department of Defense, or designated for its use, that are subject to
an integrated natural resources management plan (INRMP) prepared under
section 101 of the Sikes Act (16 U.S.C. 670a), if the Secretary
determines in writing that such plan provides a benefit to the species
for which critical habitat is proposed for designation.'' There are no
Department of Defense lands with a completed INRMP within the final
critical habitat designation.
Consideration of Impacts Under Section 4(b)(2) of the Act
Section 4(b)(2) of the Act states that the Secretary shall
designate and make revisions to critical habitat on the basis of the
best available scientific data after
[[Page 39086]]
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
statute on its face, as well as the legislative history, are clear that
the Secretary has broad discretion regarding which factor(s) to use and
how much weight to give to any factor.
The first sentence in section 4(b)(2) of the Act requires that we
take into consideration the economic, national security, or other
relevant impacts of designating any particular area as critical
habitat. We describe below the process that we undertook for taking
into consideration each category of impacts and our analyses of the
relevant impacts.
Consideration of Economic Impacts
Section 4(b)(2) of the Act and its implementing regulations require
that we consider the economic impact that may result from a designation
of critical habitat. To assess the probable economic impacts of a
designation, we must first evaluate specific land uses or activities
and projects that may occur in the area of the critical habitat. We
then must evaluate the impacts that a specific critical habitat
designation may have on restricting or modifying specific land uses or
activities for the benefit of the species and its habitat within the
areas proposed. We then identify which conservation efforts may be the
result of the species being listed under the Act versus those
attributed solely to the designation of critical habitat for this
particular species. The probable economic impact of a proposed critical
habitat designation is analyzed by comparing scenarios both ``with
critical habitat'' and ``without critical habitat.''
The ``without critical habitat'' scenario represents the baseline
for the analysis, which includes the existing regulatory and socio-
economic burden imposed on landowners, managers, or other resource
users potentially affected by the designation of critical habitat
(e.g., under the Federal listing as well as other Federal, State, and
local regulations). The baseline, therefore, represents the costs of
all efforts attributable to the listing of the species under the Act
(i.e., conservation of the species and its habitat incurred regardless
of whether critical habitat is designated). The ``with critical
habitat'' scenario describes the incremental impacts associated
specifically with the designation of critical habitat for the species.
The incremental conservation efforts and associated impacts would not
be expected without the designation of critical habitat for the
species. In other words, the incremental costs are those attributable
solely to the designation of critical habitat, above and beyond the
baseline costs. These are the costs we use when evaluating the benefits
of inclusion and exclusion of particular areas from the final
designation of critical habitat should we choose to conduct a
discretionary 4(b)(2) exclusion analysis.
For this particular designation, we developed an incremental
effects memorandum (IEM) considering the probable incremental economic
impacts that may result from the proposed designation of critical
habitat. The information contained in our IEM was then used to develop
a screening analysis of the probable effects of the designation of
critical habitat for the elfin-woods warbler (Abt Associates, Inc.
2016). We began by conducting a screening analysis of the proposed
designation of critical habitat in order to focus our analysis on the
key factors that are likely to result in incremental economic impacts.
The purpose of the screening analysis is to filter out particular
geographic areas of critical habitat that are already subject to such
protections and are, therefore, unlikely to incur incremental economic
impacts. In particular, the screening analysis considers baseline costs
(i.e., absent critical habitat designation) and includes probable
economic impacts where land and water use may be subject to
conservation plans, land management plans, best management practices,
or regulations that protect the habitat area as a result of the Federal
listing status of the species. Ultimately, the screening analysis
allows us to focus our analysis on evaluating the specific areas or
sectors that may incur probable incremental economic impacts as a
result of the designation. The screening analysis also assesses whether
units are unoccupied by the species and thus may require additional
management or conservation efforts as a result of the critical habitat
designation for the species; these additional efforts may incur
incremental economic impacts. This screening analysis combined with the
information contained in our IEM are what we consider our draft
economic analysis (DEA) of the proposed critical habitat designation
for the elfin-woods warbler; our DEA is summarized in the narrative
below. The DEA, dated March 7, 2016, was made available for public
review from June 23, 2016, through August 22, 2016 (81 FR 40632). We
did not receive any public comments on the DEA. A copy of the DEA may
be obtained by contacting the Caribbean Ecological Services Field
Office (see ADDRESSES) or by downloading from the internet at http://www.regulations.gov.
Executive Orders (E.O.s) 12866 and 13563 direct Federal agencies to
assess the costs and benefits of available regulatory alternatives in
quantitative (to the extent feasible) and qualitative terms. Consistent
with the E.O. regulatory analysis requirements, our effects analysis
under the Act may take into consideration impacts to both directly and
indirectly affected entities, where practicable and reasonable. If
sufficient data are available, we assess to the extent practicable the
probable impacts to both directly and indirectly affected entities. As
part of our screening analysis, we considered the types of economic
activities that are likely to occur within the areas likely affected by
the critical habitat designation. In our evaluation of the probable
incremental economic impacts that may result from the proposed
designation of critical habitat for the elfin-woods warbler, first we
identified, in the IEM dated December 7, 2015, probable incremental
economic impacts associated with the following categories of
activities: Forest management, silviculture/timber management,
implementation of conservation/restoration practices, human-induced
fire management, development or improvement of existing infrastructure
(e.g., roads, water intakes, water pipelines, electric transmission
lines), recreation facilities, agriculture, and single house
development funded by the U.S. Department of Housing and Urban
Development (HUD). We considered each industry or category
individually. Additionally, we considered whether their activities have
any Federal involvement. Critical habitat designation generally will
not affect activities that do not have any Federal involvement; under
the Act, designation of critical habitat only affects activities
conducted, funded, permitted, or authorized by Federal agencies. In
areas where the elfin-woods warbler is present, Federal agencies
already are required to consult with the Service under section 7 of the
Act on activities they fund, permit, or implement that may affect the
species. When this final critical habitat designation rule becomes
[[Page 39087]]
effective, consultations to avoid the destruction or adverse
modification of critical habitat will be incorporated into the existing
consultation process.
In our IEM, we attempted to clarify the distinction between the
effects that will result from the species being listed and those
attributable to the critical habitat designation (i.e., difference
between the jeopardy and adverse modification standards) for the elfin-
woods warbler's critical habitat. Because the majority of the critical
habitat units are already managed for the conservation of natural
resources, all units have co-occurring federally listed species, and
two of the three units are occupied by the elfin-woods warbler, it is
unlikely that costs will result from section 7 consultations
considering critical habitat alone, consultations resulting in adverse
modifications alone, or project modifications attributable to critical
habitat alone. The only incremental costs predicted are the
administrative costs due to additional consideration of adverse
modification of critical habitat during section 7 consultations.
Based on estimates from existing section 7 consultations on a
surrogate listed species, the Puerto Rican sharp-shinned hawk, the DEA
predicts that 5.4 requests for technical assistance, 2.4 informal
consultations, and 0.6 formal consultations per year will consider
critical habitat for the elfin-woods warbler. The 363 ac (146.9 ha) we
are including in Unit 1 of our critical habitat designation, after the
proposed designation and DEA were complete, does not significantly
alter the economic predictions. Within this 363 ac, there have been no
consultations and one species list request in the past 5 years.
In addition, because there are other federally listed species in
all units of the critical habitat for elfin-woods warbler, the Service
finds that the designation of critical habitat for the elfin-woods
warbler is unlikely to lead to changes in permitting processes by
Commonwealth or local agencies or other land managers.
We note that ``any project modifications or conservation measures
recommended to prevent adverse modification of the elfin-woods
warbler's critical habitat will not differ from project modifications
and conservation measures recommended to prevent the jeopardy of other
federally listed co-occurring species in the area (e.g., Puerto Rican
sharp-shinned hawk)'' (Abt Associates, Incorporated 2016, p. 11).
Federally listed species occupy areas in the three critical habitat
units for the elfin-woods warbler. Therefore, we do not expect
substantial impacts within any geographic area or to any sector as a
result of this critical habitat designation.
Based on peer review comments that identified an area that is
occupied by the species and has the PBFs that support the species, we
added 363 ac (146.9 ha) to proposed critical habitat in Unit 1
(Maricao). This added area consists of 355 ac within lands managed for
conservation by the Puerto Rico Department of Natural and Environmental
Resources, with the remaining 8 ac privately owned. The incremental
economic effects of this addition are minimal, because the area being
added is 1.3 percent of the total critical habitat, predominantly
contains lands managed for conservation, and harbors federally listed
species covered under section 7 of the Act.
Based on the finding that the critical habitat designation will
have minimal impact on land use or other activities (i.e., there is
little incremental difference due to the designation), the DEA
concludes that benefits will also be minimal. Possible benefits, aside
from the conservation of elfin-woods warbler, could include cultural
heritage benefits and other non-use benefits. Due to limited data
availability, however, the DEA does not monetize these benefits.
Exclusions Based on Economic Impacts
The first sentence of section 4(b)(2) of the Act requires the
Service to consider the economic impacts (as well as the impacts on
national security and any other relevant impacts) of designating
critical habitat. In addition, economic impacts may, for some
particular areas, play an important role in the discretionary section
4(b)(2) exclusion analysis under the second sentence of section
4(b)(2). In both contexts, the Service has considered the probable
incremental economic impacts of the designation. When the Service
undertakes a discretionary section 4(b)(2) exclusion analysis with
respect to a particular area, we weigh the economic benefits of
exclusion (and any other benefits of exclusion) against any benefits of
inclusion (primarily the conservation value of designating the area).
The conservation value may be influenced by the level of effort needed
to manage degraded habitat to the point where it could support the
listed species.
The Service uses its discretion in determining how to weigh
probable incremental economic impacts against conservation value. The
nature of the probable incremental economic impacts, and not
necessarily a particular threshold level, triggers considerations of
exclusions based on probable incremental economic impacts. For example,
if an economic analysis indicates high probable incremental impacts of
designating a particular critical habitat unit of lower conservation
value (relative to the remainder of the designation), the Service may
consider exclusion of that particular unit.
As discussed above, the Service considered the economic impacts of
the critical habitat designation and the Secretary is not exercising
his discretion to exclude any areas from this designation of critical
habitat for the elfin-woods warbler based on economic impacts.
Exclusions Based on Impacts on National Security and Homeland Security
Under section 4(b)(2) of the Act, we consider whether there are
lands where a national security impact might exist. We have determined
that the lands within the final designation of critical habitat for the
elfin-woods warbler are not owned or managed by the Department of
Defense or Department of Homeland Security, and, therefore, we
anticipate no impact on national security. Consequently, the Secretary
is not exercising his discretion to exclude any areas from the final
designation based on impacts on national security.
Exclusions Based on Other Relevant Impacts
Under section 4(b)(2) of the Act, we consider any other relevant
impacts, in addition to economic impacts and impacts on national
security. We consider a number of factors including whether there are
permitted conservation plans covering the species in the area such as
HCPs, safe harbor agreements, or candidate conservation agreements with
assurances, or whether there are non-permitted conservation agreements
and partnerships that would be encouraged by designation of, or
exclusion from, critical habitat. In addition, we look at the existence
of tribal conservation plans and partnerships and consider the
government-to-government relationship of the United States with tribal
entities. We also consider any social impacts that might occur because
of the designation.
In preparing this final rule, we have determined that some areas
within the final designation are included in management plans or other
conservation agreements such as the Service's Wildlife Conservation
Extension Agreements with private landowners, Natural Resources
Conservation Service's conservation contracts with private landowners,
cooperative
[[Page 39088]]
agreements with nongovernmental organizations (NGOs), and the CCA
signed at the end of 2014 among the Service, U.S. Forest Service, and
PRDNER to implement conservation practices for the recovery of the
elfin-woods warbler within EYNF and MCF.
Although the initiatives with private landowners and NGOs promote
the restoration and enhancement of elfin-woods warbler habitat adjacent
to the EYNF and MCF, potential challenges such as limited resources and
uncertainty about landowners' participation may affect the
implementation of conservation practices that mitigate impacts of
agricultural practices and ensure the conservation of the species'
essential habitat. We do not anticipate any negative effects of
designating critical habitat in areas where existing partnerships
occur. Further, there are no tribal lands in Puerto Rico. Therefore,
the Secretary is not exercising his discretion to exclude any areas
from the final designation based on other relevant impacts.
Required Determinations
Regulatory Planning and Review (Executive Orders 12866 and 13563)
Executive Order 12866 provides that the Office of Information and
Regulatory Affairs in the Office of Management and Budget (OMB) will
review all significant rules. The Office of Information and Regulatory
Affairs has waived their review regarding their significance
determination of this rule.
Executive Order 13563 reaffirms the principles of E.O. 12866 while
calling for improvements in the nation's regulatory system to promote
predictability, to reduce uncertainty, and to use the best, most
innovative, and least burdensome tools for achieving regulatory ends.
The executive order directs agencies to consider regulatory approaches
that reduce burdens and maintain flexibility and freedom of choice for
the public where these approaches are relevant, feasible, and
consistent with regulatory objectives. E.O. 13563 emphasizes further
that regulations must be based on the best available science and that
the rulemaking process must allow for public participation and an open
exchange of ideas. We have developed this rule in a manner consistent
with these requirements.
Regulatory Flexibility Act (5 U.S.C. 601 et seq.)
Under the Regulatory Flexibility Act (RFA; 5 U.S.C. 601 et seq.),
as amended by the Small Business Regulatory Enforcement Fairness Act of
1996 (SBREFA; 5 U.S.C. 801 et seq.), 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 RFA to require Federal agencies to provide a
certification statement of the factual basis for certifying that the
rule will not have a significant economic impact on a substantial
number of small entities.
According to the Small Business Administration, small entities
include small organizations such as independent nonprofit
organizations; small governmental jurisdictions, including school
boards and city and town governments that serve fewer than 50,000
residents; and small businesses (13 CFR 121.201). Small businesses
include manufacturing and mining concerns with fewer than 500
employees, wholesale trade entities with fewer than 100 employees,
retail and service businesses with less than $5 million in annual
sales, general and heavy construction businesses with less than $27.5
million in annual business, special trade contractors doing less than
$11.5 million in annual business, and agricultural businesses with
annual sales less than $750,000. To determine if potential economic
impacts to these small entities are significant, we considered the
types of activities that might trigger regulatory impacts under this
designation as well as types of project modifications that may result.
In general, the term ``significant economic impact'' is meant to apply
to a typical small business firm's business operations.
Under the RFA, as amended, and as understood in the light of recent
court decisions, Federal agencies are required to evaluate the
potential incremental impacts of rulemaking only on those entities
directly regulated by the rulemaking itself and, therefore, are not
required to evaluate the potential impacts to indirectly regulated
entities. The regulatory mechanism through which critical habitat
protections are realized is section 7 of the Act, which requires
Federal agencies, in consultation with the Service, to ensure that any
action authorized, funded, or carried out by the agency is not likely
to destroy or adversely modify critical habitat. Therefore, under
section 7, only Federal action agencies are directly subject to the
specific regulatory requirement (avoiding destruction and adverse
modification) imposed by critical habitat designation. Consequently, it
is our position that only Federal action agencies will be directly
regulated by this designation. There is no requirement under RFA to
evaluate the potential impacts to entities not directly regulated.
Moreover, Federal agencies are not small entities. Therefore, because
no small entities are directly regulated by this rulemaking, the
Service certifies that the final critical habitat designation will not
have a significant economic impact on a substantial number of small
entities.
During the development of this final rule, we reviewed and
evaluated all information submitted during the comment period that may
pertain to our consideration of the probable incremental economic
impacts of this critical habitat designation. Based on this
information, we affirm our certification that this final critical
habitat designation will not have a significant economic impact on a
substantial number of small entities, and a regulatory flexibility
analysis is not required.
Executive Order 13771
We do not believe this rule is an E.O. 13771 (``Reducing Regulation
and Controlling Regulatory Costs'') (82 FR 9339, February 3, 2017)
regulatory action because we believe this rule is not significant under
E.O. 12866; however, the Office of Information and Regulatory Affairs
has waived their review regarding their E.O. 12866 significance
determination of this rule.
Energy Supply, Distribution, or Use--Executive Order 13211
Executive Order 13211 (Actions Concerning Regulations That
Significantly Affect Energy Supply, Distribution, or Use) requires
agencies to prepare Statements of Energy Effects when undertaking
certain actions. OMB has provided guidance for implementing this
Executive Order that outlines nine outcomes that may constitute ``a
significant adverse effect'' when compared to not taking the regulatory
action under consideration. Our economic analysis finds that none of
these criteria are relevant to this analysis. Thus, based on
information in the economic analysis, energy-related impacts associated
with elfin-woods warbler conservation activities within critical
habitat are not expected. As such, the designation of critical habitat
is not expected to significantly affect
[[Page 39089]]
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
et seq.), we make the following findings:
(1) This rule will not produce a Federal mandate. In general, a
Federal mandate is a provision in legislation, statute, or regulation
that would impose an enforceable duty upon State, local, or tribal
governments, or the private sector, and includes both ``Federal
intergovernmental mandates'' and ``Federal private sector mandates.''
These terms are defined in 2 U.S.C. 658(5)-(7). ``Federal
intergovernmental mandate'' includes a regulation that ``would impose
an enforceable duty upon State, local, or tribal governments'' with two
exceptions. It excludes ``a condition of Federal assistance.'' It also
excludes ``a duty arising from participation in a voluntary Federal
program,'' unless the regulation ``relates to a then-existing Federal
program under which $500,000,000 or more is provided annually to State,
local, and tribal governments under entitlement authority,'' if the
provision would ``increase the stringency of conditions of assistance''
or ``place caps upon, or otherwise decrease, the Federal Government's
responsibility to provide funding,'' and the State, local, or tribal
governments ``lack authority'' to adjust accordingly. At the time of
enactment, these entitlement programs were: Medicaid; Aid to Families
with Dependent Children work programs; Child Nutrition; Food Stamps;
Social Services Block Grants; Vocational Rehabilitation State Grants;
Foster Care, Adoption Assistance, and Independent Living; Family
Support Welfare Services; and Child Support Enforcement. ``Federal
private sector mandate'' includes a regulation that ``would impose an
enforceable duty upon the private sector, except (i) a condition of
Federal assistance or (ii) a duty arising from participation in a
voluntary Federal program.''
The designation of critical habitat does not impose a legally
binding duty on non-Federal Government entities or private parties.
Under the Act, the only regulatory effect is that Federal agencies must
ensure that their actions do not destroy or adversely modify critical
habitat under section 7. While non-Federal entities 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 onto State governments.
(2) We do not believe that this rule will significantly or uniquely
affect small governments because the majority of the critical habitat
units are already managed for natural resource conservation by the
Federal government or the Commonwealth of Puerto Rico, and all critical
habitat units have co-occurring federally listed species that are
already being considered by the Commonwealth and municipalities for any
actions proposed in the area. Therefore, a Small Government Agency Plan
is not required.
Takings--Executive Order 12630
In accordance with E.O. 12630 (Government Actions and Interference
with Constitutionally Protected Private Property Rights), we have
analyzed the potential takings implications of designating critical
habitat for elfin-woods warbler in a takings implications assessment.
The Act does not authorize the Service to regulate private actions on
private lands or confiscate private property as a result of critical
habitat designation. Designation of critical habitat does not affect
land ownership, or establish any closures, or restrictions on use of or
access to the designated areas. Furthermore, the designation of
critical habitat does not affect landowner actions that do not require
Federal funding or permits, nor does it preclude development of habitat
conservation programs or issuance of incidental take permits to permit
actions that do require Federal funding or permits to go forward.
However, Federal agencies are prohibited from carrying out, funding, or
authorizing actions that would destroy or adversely modify critical
habitat. A takings implications assessment has been completed and
concludes that this designation of critical habitat for elfin-woods
warbler does not pose significant takings implications for lands within
or affected by the designation.
Federalism--Executive Order 13132
In accordance with E.O. 13132 (Federalism), this rule does not have
significant Federalism effects. A Federalism assessment is not
required. In keeping with Department of the Interior and Department of
Commerce policy, we requested information from, and coordinated
development of the proposed critical habitat designation with,
appropriate State resource agencies in Puerto Rico. We did not receive
comments from Federal agencies for this rule. From a federalism
perspective, the designation of critical habitat directly affects only
the responsibilities of Federal agencies. The Act imposes no other
duties with respect to critical habitat, either for States and local
governments, or for anyone else. As a result, the rule does not have
substantial direct effects either on the States, or on the relationship
between the national government and the States, or on the distribution
of powers and responsibilities among the various levels of government.
The designation may have some benefit to these governments because the
areas that contain the features essential to the conservation of the
species are more clearly defined, and the physical or biological
features of the habitat necessary to the conservation of the species
are specifically identified. This information does not alter where and
what federally sponsored activities may occur. However, it may assist
these local governments in long-range planning because they no longer
have to wait for case-by-case section 7 consultations to occur.
Where State and local governments require approval or authorization
from a Federal agency for actions that may affect critical habitat,
consultation under section 7(a)(2) would be required. While non-Federal
entities that receive Federal funding, assistance, or permits, or that
otherwise require approval or authorization from a Federal agency for
an action, may be indirectly impacted by the designation of critical
habitat, the legally binding duty to avoid destruction or adverse
modification of critical habitat rests squarely on the Federal agency.
Civil Justice Reform--Executive Order 12988
In accordance with Executive Order 12988 (Civil Justice Reform),
the Office of the Solicitor has determined that the rule does not
unduly burden the judicial system and that it meets the requirements of
sections 3(a) and 3(b)(2) of the Order. We are designating critical
habitat in accordance with the provisions of the Act. To assist the
public in understanding the habitat needs of the species, this rule
identifies the elements of physical or biological
[[Page 39090]]
features essential to the conservation of the elfin-woods warbler. The
designated areas of critical habitat are presented on maps, and the
rule provides several options for the interested public to obtain more
detailed location information, if desired.
Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.)
This rule does not contain information collection requirements, and
a submission to the Office of Management and Budget (OMB) under the
Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.) is not
required. We may not conduct or sponsor and you are not required to
respond to a collection of information unless it displays a currently
valid OMB control number.
National Environmental Policy Act (42 U.S.C. 4321 et seq.)
It is our position that, outside the jurisdiction of the U.S. Court
of Appeals for the Tenth Circuit, we do not need to prepare
environmental analyses pursuant to the National Environmental Policy
Act (NEPA; 42 U.S.C. 4321 et seq.) in connection with designating
critical habitat under the Act. We published a notice outlining our
reasons for this determination in the Federal Register on October 25,
1983 (48 FR 49244). This position was upheld by the U.S. Court of
Appeals for the Ninth Circuit (Douglas County v. Babbitt, 48 F.3d 1495
(9th Cir. 1995), cert. denied 516 U.S. 1042 (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 (Consultation and
Coordination With Indian Tribal Governments), and the Department of the
Interior's manual at 512 DM 2, we readily acknowledge our
responsibility to communicate meaningfully with recognized Federal
Tribes on a government-to-government basis. In accordance with
Secretarial Order 3206 of June 5, 1997 (American Indian Tribal Rights,
Federal-Tribal Trust Responsibilities, and the Endangered Species Act),
we readily acknowledge our responsibilities to work directly with
tribes in developing programs for healthy ecosystems, to acknowledge
that tribal lands are not subject to the same controls as Federal
public lands, to remain sensitive to Indian culture, and to make
information available to tribes. As discussed above, there are no
tribal lands in Puerto Rico, and therefore, we have identified no
tribal interests that will be affected by this final rulemaking.

elevations ranging from 300 to 750 m (984 to 2,460 ft).
(3) Critical habitat does not include manmade structures (such as
buildings, aqueducts, runways, roads, and other paved areas) and the
land on which they are located existing within the legal boundaries on
July 30, 2020.
(4) Critical habitat map units. Data layers defining map units were
created by delineating habitats that contain at least one or more of
the physical or biological features defined in paragraph (2) of this
entry, over a U.S. Department of Agriculture 2007 digital orthophoto
mosaic, over a base of U.S. Geological Survey digital topographic map
quadrangle, and with the use of a digital landcover layer. The
resulting critical habitat unit was then mapped using State Plane North
American Datum 83 coordinates. The maps in this entry, as modified by
any accompanying regulatory text, establish the boundaries of the
critical habitat designation. The coordinates or plot points or both on
which each map is based are available to the public at the Service's
internet site, http://www.regulations.gov under Docket No. FWS-R4-ES-
2020-0030, and at the field office responsible for this designation.
You may obtain field office location information by contacting one of
the Service regional offices, the addresses of which are listed at 50
CFR 2.2.
