Fish and Wildlife Service

Endangered and Threatened Wildlife and Plants; 5-Year Reviews of 
18 Caribbean Species

AGENCY: Fish and Wildlife Service, Interior.

ACTION: Notice of initiation of 5-year reviews; Request for public 


SUMMARY: We, the U.S. Fish and Wildlife Service (Service), are 
initiating 5-year reviews of 18 Caribbean species under section 4(c)(2) 
of the Endangered Species Act of 1973, as amended (Act). The purpose of 
a 5-year review is to ensure that the classification of a species as 
threatened or endangered on the List of Endangered and Threatened 
Wildlife and Plants is accurate. The 5-year review is an assessment of 
the best scientific and commercial data available at the time of the 

DATES: To allow us adequate time to conduct our reviews, we must 
receive all information you submit for our consideration on or before 
November 20, 2007. However, we will continue to accept new information 
about any listed species at any time.

ADDRESSES: Send information on the 18 listed species to the Field 
Supervisor, Caribbean Field Office, U.S. Fish and Wildlife Service, 
Post Office Box 491, Boquer[oacute]n, PR 00622. Information we receive 
in response to this notice will be available for public inspection by 
appointment, during normal business hours, at the Cabo Rojo National 
Wildlife Refuge, Ecological Service Office, Carr. 301, Km. 5.1, Bo. 
Corozo, Boquer[oacute]n, PR, 00622.

FOR FURTHER INFORMATION CONTACT: Marelisa Rivera, Boquer[oacute]n, 
Puerto Rico, at address above (telephone, 787/851-7297, ext. 231).

SUPPLEMENTARY INFORMATION: We are initiating 5-year reviews of 18 
Caribbean species: The Puerto Rican broad-winged hawk (Buteo 
platypterus brunnescens), Puerto Rican sharp-shinned hawk (Accipiter 
striatus venator), yellow-shouldered blackbird (Agelaius xanthomus), 
Mona boa (Epicrates monensis monensis), Monito gecko (Sphaerodactylus 
micropithecus), Mona ground iguana (Cyclura cornuta stejnegeri), St. 
Croix ground lizard (Ameiva polops), Puerto Rican crested toad 
(Peltophryne lemur), Aristida chaseae (no common name), pelos del 
diablo (Aristida portoricensis), palma de manaca (Calyptronoma 
rivalis), Cranichis ricartii (no common name), higuero de Sierra 
(Crescentia portoricensis), Eugenia woodburyana (no common name), 
Lyonia truncata var. proctorii (no common name), palo de rosa 
(Ottoschulzia rhodoxylon), c[oacute]bana negra (Stahlia monosperma), 
and Vernonia proctorii (no common name) under the Endangered Species 
Act of 1973, as amended (16 U.S.C. 1531 et seq.; the Act). Of the above 
list of 18 species, the following 3 are currently listed as threatened: 
Mona boa, Puerto Rican crested toad, and c[oacute]bana negra; the other 
15 species are currently listed as endangered. Our regulations at 50 
CFR 424.21 require that we publish a notice in the Federal Register 
announcing those species currently under active review.
    Under the Act, we maintain a List of Endangered and Threatened 
Wildlife and Plants at 50 CFR 17.11 (for animals) and 50 CFR 17.12 (for 
plants) (collectively referred to as the list). The list is also 
available on our Internet site at http://endangered.fws.gov/wildlife.html#Species.
 Section 4(c)(2)(A) of the Act requires that we 

conduct a review of listed species at least once every 5 years. Then, 
on the basis of such reviews, under section 4(c)(2)(B), we determine 
whether or not we should remove any species from the List (delist), or 
reclassify it from endangered to threatened or from threatened to 
endangered. Delisting a species must be supported by the best 
scientific and commercial data available and only considered if such 
data substantiate that the species is neither endangered nor threatened 
for one or more of the following reasons: (1) The species is considered 
extinct; (2) the species is considered to be recovered; and/or (3) the 
original data available when the species was listed, or the 
interpretation of such data, were in error. Any change in Federal 
classification would require a separate rulemaking process. We publish 
amendments to the list through final rules in the Federal Register.

What Information Do We Consider in Our Review?

    A 5-year review considers the best scientific and commercial data 
that has become available since the current listing determination or 
most recent status review of each species, such as:
    A. Species biology, including but not limited to population trends, 
distribution, abundance, demographics, and genetics;
    B. Habitat conditions, including but not limited to amount, 
distribution, and suitability;
    C. Conservation measures that have been implemented to benefit the 
    D. Threat status and trends (see five factors under heading ``How 
do we determine whether a species is endangered or threatened?''); and
    E. Other new information, data, or corrections, including but not 
limited to taxonomic or nomenclatural changes, identification of 
erroneous information contained in the List, and improved analytical 

We request any new information concerning the status of any of these 18 
species. Support any information you submit with documentation such as 
maps, bibliographic references, methods used to gather and analyze the 
data, and/or copies of any pertinent publications, reports, or letters 
by knowledgeable sources.


    The following definitions will assist you as you submit information 
regarding the species:
    A. Species includes any species or subspecies of fish, wildlife, or 
plant, and any distinct population segment of any species of vertebrate 
which interbreeds when mature.
    B. Endangered means any species that is in danger of extinction 
throughout all or a significant portion of its range.
    C. Threatened means any species that is likely to become an 
endangered species within the foreseeable future throughout all or a 
significant portion of its range.

How Do We Determine Whether a Species Is Endangered or Threatened?

    Section 4(a)(1) of the Act establishes that we determine whether a 
species is endangered or threatened based on one or more of the 
following five factors:
    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 

Section 4(a)(1) of the Act requires that our determination be made on 
the basis of the best scientific and commercial data available.

What Could Happen as a Result of Our Review?

    If we find that there is new information concerning any of these 18 
species indicating that a change in classification may be warranted, we 
may propose a new rule that could do one of the following: (a) 
Reclassify the species from endangered to threatened (downlist); (b) 
reclassify the species from threatened to endangered (uplist);

[[Page 54062]]

or (c) delist the species. If we determine that a change in 
classification is not warranted, then the species will remain on the 
List under its current status.
