Endangered and Threatened Wildlife and Plants; 90-Day Finding on
a Petition To List the Coqui Llanero (Eleutherodactylus juanariveroi)
as Endangered
AGENCY: Fish and Wildlife Service, Interior.
ACTION: Notice of petition finding and initiation of status review.
-----------------------------------------------------------------------
SUMMARY: We, the U.S. Fish and Wildlife Service (the Service), announce
a 90-day finding on a petition to list coqui llanero (Eleutherodactylus
juanariveroi), a tree frog, as threatened or endangered under the
Endangered Species Act of 1973, as amended (Act). Following our review
of the petition, we find that it provides substantial scientific or
commercial information indicating that listing this species may be
warranted. Therefore, with the publication of this notice, we initiate
a status review to determine if listing the coqui llanero is warranted.
To ensure that the status review is comprehensive, we request
scientific and commercial data and other information regarding this
species. We will initiate a determination on critical habitat for this
species if and when we initiate a listing action.
DATES: We made the finding announced in this document on July 8, 2009.
To allow us adequate time to conduct this review, we request that
information be submitted on or before September 8, 2009.
ADDRESSES: You may submit information by one of the following methods:

SUPPLEMENTARY INFORMATION:
Information Solicited
When we make a finding that a petition presents substantial
information indicating that listing a species may be warranted, the Act
(16 U.S.C. 1531 et seq.) requires us to promptly commence a review of
the status of the species. To ensure that the status review is complete
and based on the best available scientific and commercial information,
we seek information on the coqui llanero. We request information from
the public, other concerned governmental agencies, Native American
Tribes, the scientific community, industry, or any other interested
parties concerning the status of the coqui llanero. We seek information
regarding:
(1) The species' historical and current status and distribution,
its biology and ecology, and ongoing conservation measures for the
species and its habitat;
(2) Information relevant to the factors that are the basis for our
making any listing determination for a species under section 4(a) of
the Act, which are:
(a) The present or threatened destruction, modification, or
curtailment of the species' habitat or range;
(b) overutilization for commercial, recreational, scientific, or
educational purposes;
(c) disease or predation;
(d) the inadequacy of existing regulatory mechanisms; or
(e) other natural or manmade factors affecting its continued
existence and threats to the species or its habitat; and
(3) Information on the effects of climate change, sea-level change,
and water temperature change on the distribution and abundance of the
species.
If we determine that listing the species is warranted, we intend to
propose critical habitat to the maximum extent prudent and determinable
at the time we propose the listing. Therefore, with regard to areas
within the geographical range currently occupied by the coqui llanero,
we also request data and information on what may constitute physical or
biological features essential to the conservation of the species, where
these features are currently found, and whether any of these features
may require special management considerations or protection. In
addition, we request data and information regarding whether there are
areas outside the geographical area occupied by the species that are
essential to the conservation of the species. Please provide specific
comments and information as to what, if any, critical habitat you think
we should propose for designation if the species is proposed for
listing, and why such habitat meets the requirements of the Act.
Please note that submissions merely stating support for or
opposition to the action under consideration without providing
supporting information, although noted, will not be considered in
making a determination, as section 4(b)(1)(A) of the Act (16 U.S.C.
1531 et seq.) directs that determinations as to whether any species is
a threatened or endangered species must be made ``solely on the basis
of the best scientific and commercial data available.'' Based on the
status review, we will issue a 12-month finding on the petition, as
provided in section 4(b)(3)(B) of the Act.
You may submit your information concerning this status review by
one of the methods listed in the ADDRESSES section.
If you submit information via http://www.regulations.gov, your
entire submission--including any personal identifying information--will
be posted on the Web site. If your submission is made via a hardcopy
that includes personal identifying information, you may request at the
top of your document that we withhold your personal information from
public review. However, we cannot guarantee that we will be able to do
so. We will post all hardcopy comments on http://www.regulations.gov.
Information and materials we receive, as well as supporting
documentation we used in preparing this finding, will be available for
public inspection on http://www.regulations.gov, or by appointment,
during normal business hours, at the U.S. Caribbean Ecological Services
Field Office (see FOR FURTHER INFORMATION CONTACT section).
Background
Section 4(b)(3)(A) of the Act requires that we make a finding on
whether a petition to list, delist, or reclassify a species presents
substantial scientific or commercial information indicating that
[[Page 32511]]
the petitioned action may be warranted. We are to base this finding on
information provided in the petition, supporting information submitted
with the petition, and information otherwise available in our files. To
the maximum extent practicable, we are to make this finding within 90
days of our receipt of the petition and publish our notice of the
finding promptly in the Federal Register.
Our standard for substantial scientific or commercial information
within the Code of Federal Regulations (CFR) with regard to a 90-day
petition finding is ``that amount of information that would lead a
reasonable person to believe that the measure proposed in the petition
may be warranted'' (50 CFR 424.14(b)). If we find that substantial
scientific or commercial information was presented, we are required to
promptly commence a status review of the species.
On May 22, 2007, we received a petition dated May 11, 2007, from
the Caribbean Primate Research Center requesting that we list the coqui
llanero as endangered under the Act. The petition also requested that
we designate critical habitat concurrently with listing, if listing
occurs. The petition clearly identified itself as such and included the
requisite identification information for the petitioners, as required
in 50 CFR 424.14(a). In a July 23, 2007, letter to the petitioners, we
responded that we had reviewed the petition and determined that an
emergency listing was not necessary. We also stated that we would not
be able to address the petition until funding became available. Actions
in this petition were precluded by court orders and settlement
agreements for other listing actions that required nearly all of our
listing funds for fiscal year 2007. However, in fiscal year 2008,
funding became available, enabling us to address this petition.
Accordingly, this finding addresses the petition. On January 22, 2009,
we received an amended petition dated January 13, 2008. The amended
petition included literature references published in 2007, provided
photographs and maps, and updated information on current threats to the
species.
Species Information
Neftali Rios-L[oacute]pez and Richard Thomas first collected the
coqui llanero (Eleutherodactylus juanariveroi), a tree frog, in 2005
from a seasonally flooded herbaceous wetland near the U.S. Naval
Security Group Activity Sabana Seca (USNS-GASS) property and the
Caribbean Primate Research Center, Toa Baja, Puerto Rico. The coqui
llanero was later described as a new species of the genus
Eleutherodactylus, family Leptodactylidae, in 2007. Although the new
species is similar to the Eleutherodactylus gryllus, differences in
morphological ratios, body coloration, frequency of calls, call
structure, DNA, and habitat association indicate that it is a well-
differentiated species (Rios-L[oacute]pez and Thomas 2007, pp. 53-60;
Caribbean Primate Research Center 2007, p. 1; Caribbean Primate
Research Center 2008, p. 1). At the time of this determination, this
endemic Puerto Rican tree frog is only known from this type locality
(Rios-L[oacute]pez and Thomas 2007, p. 60; Caribbean Primate Research
Center 2007, p. 1; Departamento de Recursos Naturales y Ambientales
(DRNA) 2007a, p. 3; DRNA 2007b, p. 1; Caribbean Primate Research Center
2008, p. 2). It is only known to occur in the Sabana Seca-Ingenio Ward,
Toa Baja, a municipality of Puerto Rico located on the northern coast,
north of Toa Alta and Bayam[oacute]n; east of Dorado; and west of
Cata[ntilde]o, approximately 12 miles (20 kilometers) from San Juan.
The coqui llanero is the smallest Puerto Rican Eleutherodactylus
and is the only known herbaceous-wetland specialist in Puerto Rico
within the taxonomic genus Eleutherodactylus. It has a mean snout-vent
length of 14.7 millimeters (mm) (0.58 inches (in)) in males, and 15.8
mm (0.62 in) in females. The nares (nasal passages) are prominent, and
a ridge connects them behind the snout tip, giving the tip a somewhat
squared-off appearance. The species has well-developed glands through
its body; its dorsal coloration is yellow to yellowish brown with a
light, longitudinal, reversed comma mark on each side; and its mid-
dorsal zone is broadly bifurcated (divided into two branches). The
species' communication call consists of a series of short high-pitched
notes with call duration varying from 4 to 21 seconds. The
advertisement call has the highest frequency among all Puerto Rican
Eleutherodactylus, between 7.38 and 8.28 kilohertz. The calling
activity starts at approximately 4:30 p.m. and decreases significantly
before midnight. Egg clutches comprise one to five eggs and are found
on leaf axils or leaf surfaces between 0.4 meters (m) (1.3 feet (ft))
and 1.2 m (3.9 ft) above water level (Rios-L[oacute]pez and Thomas
2007, pp. 53-62). Observers did not see parental care in the field
(Caribbean Primate Research Center 2007, p. 3; Caribbean Primate
Research Center 2008, p. 5).
The coqui llanero is only known to occur in the Sabana Seca-Ingenio
Ward, Toa Baja type locality, which consists of approximately 180
hectares (ha) (444.8 acres (ac)) of seasonally flooded palustrine
(marshy, non-tidal wetlands substantially covered with emergent
vegetation such as trees, shrubs, and moss, or fresh-water herbaceous
wetland), at 17 m (55.8 ft) above sea level (Rios-L[oacute]pez and
Thomas 2007, p. 60; Caribbean Primate Research Center 2007, p. 2).
According to the petitioner, the species' habitat may represent a
relict of an endemic habitat type (Rios-L[oacute]pez and Thomas 2007,
p. 63). The habitat is categorized as within the subtropical moist
forest life zone (Ewel and Whitmore 1973, pp. 20-38). The main
vegetation in this herbaceous wetland consists of toothed midsorus fern
(Blechnum serrulatum), willdenow's maiden fern (Thelypteris
interrupta), bulltongue arrowhead (Sagittaria lancifolia), flat sedges
(Cyperus sp.), spike rushes (Eleocharis sp.), and vines and grasses
(Caribbean Primate Research Center 2007, p. 2; Caribbean Primate
Research Center 2008, p. 2).
The majority of the individuals were found perching and calling on
the toothed midsorus fern and willdenow's maiden fern. Reproduction,
however, only occurs on the bulltongue arrowhead (Caribbean Primate
Research Center 2007, p. 2; Caribbean Primate Research Center 2008, p.
4). All specimens (45 individuals) were collected while perching,
sitting, or calling on herbaceous vegetation, mainly on ferns. Egg
clutches were found on leaf axils (21 egg clutches) or leaf surfaces (3
egg clutches) of only S. lancifolia (Rios-L[oacute]pez and Thomas 2007,
p. 60).
Five-Factor Evaluation
Section 4 of the Act (16 U.S.C. 1533), and its implementing
regulations at 50 CFR part 424, set forth procedures for adding species
to the Federal List of Endangered and Threatened Wildlife and Plants. A
species may be determined to be an endangered or threatened species due
to one or more of the five factors described in section 4(a)(1) of the
Act: (A) The present or threatened destruction, modification, or
curtailment of its habitat or range; (B) overutilization for
commercial, recreational, scientific, or educational purposes; (C)
disease or predation; (D) the inadequacy of existing regulatory
mechanisms; or (E) other natural or manmade factors affecting its
continued existence.
In making this 90-day finding, we evaluated whether information
regarding the coqui llanero, as presented in the petition and clarified
by information available in our files, is substantial, thereby
indicating that the petitioned action may be warranted. Our
[[Page 32512]]
evaluation of this information is presented below.
A. The Present or Threatened Destruction, Modification, or Curtailment
of Habitat or Range
According to the petition, the existence of the coqui llanero is
imperiled due to the existing and imminent threatened destruction,
modification, and curtailment of its wetland habitat and geographic
range. The petitioner identified three main threats under Factor A: (1)
The construction of a go-kart and motorbike racetrack in the coqui
llanero's wetland habitat, (2) urban development, and (3) contamination
from the Toa Baja Municipal Landfill. The petition claims that the
construction and operation of a go-kart and motorbike racetrack within
the vicinity of the habitat of the coqui llanero are presently
affecting the species' habitat. The petition also claims that
contamination with oil, gasoline, and other pollutants due to this
racetrack is a threat since the area is prone to flooding.
Information in our files (DRNA 2007b, pp. 23-25) supports the
petitioner's contention that the construction and operation of a
racetrack for motorbikes and go-karts located north of the habitat
would have negative impacts and is a current threat to the species. The
Commonwealth of Puerto Rico's final designation of essential critical
natural habitat for the coqui llanero (see Factor D discussion below)
shows a photograph of the flooded racetrack (DRNA 2007b, p. 25). The
text below the illustration specifies that the habitat of the coqui
llanero was filled for the construction of racetrack, and that as a
result of flooding events, contaminants such as oil and gasoline from
the track spilled frequently into the wetland (DRNA 2007b, p. 25).
As described in the petition, the Toa Baja Landfill, located inland
on top of a limestone hill, is another major threat to the coqui
llanero. The petition states that polluted waters from the continued
operation of this landfill may pose a serious threat to the coqui
llanero, because underground-contaminated waters and leachates reaching
the wetlands may change water quality, soils, and consequently plant
composition (Caribbean Primate Research Center 2007, p. 4; Caribbean
Primate Research Center 2008, pp. 6-9).
The petitioner also contends that the species and its habitat are
threatened by large-scale residential projects that are currently
planned within and around the coqui llanero habitat located within the
south tract of the former U.S. Navy NSGA Sabana Seca. The petitioner
states that the Municipality of Toa Baja (as part of its land use
plans) intends to zone the habitat, an area formerly part of the Sabana
Seca Navy Base, for residential development. The petitioner claims that
the U.S. Navy, in collaboration with the Municipality of Toa Baja, has
selected residential development as the ``preferred alternative'' for
the wetlands area within the south tract of the former navy base, which
would represent the destruction of 168 ha (416 ac) of wetlands,
including the coqui llanero's habitat.
In 2005, the U.S. Navy consulted with the Service on the sale of
the former USNS-GASS property and reuse of the land for residential
purposes. The proposed disposal mechanism for Sabana Seca involved the
marketing and sale of the property. At that time, we were not aware of
the existence of this new species and its habitat within the property.
Therefore, the Service was only concerned about the possible adverse
effects to wetland resources of future re-use and development of this
area.
The petitioners assert that the above issues substantially impact
the distribution and abundance of the coqui llanero, as well as its
habitat in all of its range. Based on the information provided in the
petition and available in our files, we conclude that the petitioners
have presented substantial information to indicate that the present or
threatened destruction or modification of habitat or range may present
a threat to this species.
B. Overutilization for Commercial, Recreational, Scientific, or
Educational Purposes
Neither the petition nor information in our files presents
information indicating that overutilization of coqui llanero for
commercial, recreational, scientific, or educational purposes is a
threat. Therefore, we find that the petition does not present
substantial information to indicate that the overutilization for
commercial, recreational, scientific, or educational purposes may
present a threat to the coqui llanero.
C. Disease or Predation
Neither the petition nor information in our files presents
information indicating that disease or predation are significant
threats to the coqui llanero. Therefore, we find that the petition does
not present substantial information to indicate that disease or
predation may present significant threats to the coqui llanero.
D. Inadequacy of Existing Regulatory Mechanisms
The petitioner claims that we need to list the species and
designate critical habitat for it because no other regulatory mechanism
protecting the species or its habitat is in place. However, according
to information in our files, the Department of Natural and
Environmental Resources (DNER) for the Commonwealth of Puerto Rico
designated the species as Critically Endangered and designated its
habitat as Essential Critical Natural Habitat under Commonwealth Law
241 and Regulation 6766 in July 2007. The designation as ``critically
endangered'' prohibits any person from taking the species: It prohibits
harm, possession, transportation, destruction, or import or export of
individuals, nests, eggs or juveniles without previous authorization
from the Secretary of DNER. Article 2 of Regulation 6766 includes all
prohibitions.
DNER designated approximately 200 ha (509 ac) as ``essential
critical natural habitat'' in accordance with Regulation 6766. Article
4.05 of this regulation specifies that an area designated as essential
critical natural habitat cannot be modified unless scientific studies
determine that such designation should be changed. Article 2.06 of this
regulation prohibits collecting, harassing, hunting, and removing,
among other activities, of listed animals within the jurisdiction of
Puerto Rico.
Because the coqui llanero's habitat is the first to be designated
as Essential Critical Natural Habitat under Commonwealth Law 241 and
Regulation 6766, no one is certain of the level of protection this law
will provide. Therefore, we conclude that the petitioners have
presented substantial information to indicate that existing regulatory
mechanisms may be inadequate to protect the coqui llanero.
E. Other Natural or Manmade Factors Affecting the Species' Continued
Existence
The petitioner asserts that the species is at risk of extinction
throughout its range as a result of its extremely limited distribution
of approximately 200 ha (494 ac). With European colonization, land was
extensively drained and modified for agricultural practices. A shift in
the Puerto Rican economy from agriculture to industry led to land
abandonment, and this species' habitat is thought to represent a relic
of an endemic herbaceous palustrine wetland. Based on the information
provided in the petition and information in our files, the species is
currently only known
[[Page 32513]]
from the Sabana-Seca-Ingenio Ward (the locality in which the species
was described), a seasonally flooded palustrine herbaceous wetland in
Toa Baja (Rios-L[oacute]pez and Thomas 2007, p. 60; Caribbean Primate
Research Center 2007, p. 2; DRNA 2007a, pp. 1-11; and DRNA 2007b, pp.
1-38; Caribbean Primate Research Center 2008, p. 2). Land conversion to
residential or commercial projects is likely to occur in the near
future because the Municipality of Toa Baja (as part of its land use
plans) intends to zone the habitat, an area formerly part of the Sabana
Seca Navy Base, for residential development. This species has not been
found in any other location. The species' limited range and apparent
habitat requirements may be a factor affecting the species' continued
existence.
The petitioner also asserted that the species is threatened by
other reasons related to its low reproductive capacity, highly
specialized ecological requirements, brush fires, use of herbicides and
changing climate conditions. Although the petition reports an abundance
of 450 individuals/ha (181 individuals/ac) (Caribbean Primate Research
Center 2007, p. 3; Caribbean Primate Research Center 2008, p.5), it
identified low reproductive capacity as a threat to the species. Rios-
L[oacute]pez and Thomas (2007, p. 60) found that egg clutches generally
contain 1 to 5 eggs, based on data collected from 24 egg clutches.
Rios-L[oacute]pez and Thomas (2007, p. 63) indicated that recent
surveys conducted in nearby wetlands failed to locate the species and
that apparently, there are few or no wetlands with plant composition
similar to that found in the Sabana-Seca type locality.
No additional information was provided regarding how many wetlands
have been surveyed for determining presence or absence of the species
nor what type of studies have been conducted to compare habitat
characteristics among these wetlands. However, the evidence presented
in the petition and in the scientific literature suggest that the
species is an obligate marsh-dweller (Rios-L[oacute]pez 2007, p. 62)
and has only been found in the Sabana Seca-Ingenio Ward. Also, the
petition mentions that brush fire increases the species risk of
extinction by reducing the cover of the wetland. The amended petition
mentioned that the current use of herbicides in the former base, as
part of the maintenance work on the grounds, represents a current
threat to the species. Additionally, the amended petition identified
changing climatic conditions as a possible threat to the wetland where
the coqui llanero is currently present. However, no further information
was provided supporting these threats.
To summarize, the primary natural or manmade threats appear to be
the limited distribution, low reproductive capacity, highly specialized
ecological requirements, and potential threats such as the use of
herbicides and fires to the species' habitat. Based on the information
presented in the petition and available in our files, we find that the
petition presents substantial information to indicate that other
natural or manmade factors may be affecting the continued existence of
the coqui llanero. Therefore, we find that the petition presents
substantial information for this factor.
Finding
Section 4(b)(3)(A) of the Act requires that we make a finding on
whether a petition to list, delist, or reclassify a species presents
substantial scientific or commercial information indicating that the
petitioned action may be warranted. We are to base this finding on
information provided in the petition, supporting information submitted
with the petition, and information otherwise available in our files. To
the maximum extent practicable, we are to make this finding within 90
days of our receipt of the petition and publish our notice of the
finding promptly in the Federal Register.
Our process for making this 90-day finding under section 4(b)(3)(A)
of the Act is limited to a determination of whether the information in
the petition presents ``substantial scientific and commercial
information,'' which is interpreted in our regulations as ``that amount
of information that would lead a reasonable person to believe that the
measure proposed in the petition may be warranted'' (50 CFR 424.14(b)).
As described in our five-factor analysis above, the petition presents
substantial information indicating that listing the coqui llanero as
threatened or endangered throughout its entire range may be warranted
based on Factors A, D, and E. We reviewed the petition, supporting
information provided by the petitioner, and information in our files,
and we evaluated that information to determine whether the sources
cited support the claims made in the petition.
The petition and supporting information identified numerous factors
affecting the species, including residential development, lack of
regulatory mechanisms protecting the species and its habitat, and the
limited habitat suitability available to the species. Our conclusion is
based on information that indicates that the species' continued
existence may be affected by loss and fragmentation of habitat from
land conversion, development, and habitat contamination (Factor A);
inadequate protection from threats by regulatory mechanisms (Factor D);
and other natural or manmade factors such as limited habitat and range,
low reproductive capacity, highly specialized ecological requirements,
and use of herbicides and fires (Factor E). The petition did not
contain information indicating that Factors B and C are considered a
threat to this species. As a result of this finding, we are initiating
a status review of the species. At the conclusion of the status review,
we will issue a 12-month finding, in accordance with section 4(b)(3)(B)
of the Act, as to whether or not we believe a proposal to list the
species is warranted.
The ``substantial information'' standard for a 90-day finding is
not the same as the Act's ``best scientific and commercial data''
standard that applies to a 12-month finding to determine whether a
petitioned action is warranted. A 90-day finding is not a status
assessment of the species and does not constitute a status review under
the Act. Our final determination of whether a petitioned action is
warranted is not made until we have completed a thorough status review
of the species as part of the 12-month finding on a petition, which is
conducted following a positive 90-day finding. Because the Act's
standards for 90-day and 12-month findings are different, as described
above, a positive 90-day finding does not mean that the 12-month
finding also will be positive.
