Fish and Wildlife Service, Interior.




The U.S. Fish and Wildlife Service (Service) announces a 5-year review of the Puerto Rican parrot (Amazona vittata), Puerto Rican plain pigeon (Columba (=Patagioenas) inornata wetmorei), red-cockaded woodpecker (Picoides borealis), Puerto Rican boa (Epicrates inornatus), Virgin Islands tree boa (Epicrates monensis granti), guajón (Eleutherodactylus cooki), Harrisia portoricensis (higo chumbo), and Adiantum vivesii (no common name), under section 4(c)(2) of the Endangered Species Act of 1973, as amended (Act). The purpose of reviews conducted under this section of the Act is to ensure that the classification of species as threatened or endangered on the List of Endangered and Threatened Wildlife and Plants (50 CFR 17.11 and 17.12) is accurate. The 5-year review is an assessment of the best scientific and commercial data available at the time of the review.


To allow us adequate time to conduct this review, information submitted for our consideration must be received on or before November 14, 2005. However, we will continue to accept new information about any listed species at any time.


Information submitted on the red-cockaded woodpecker should be sent to the Field Supervisor, Clemson Field Office, U.S. Fish and Wildlife Service, 2610 Lehotsky Hall, Box 341003, Clemson, South Carolina 29634. Information on the other seven listed species should be sent to the Field Supervisor, Caribbean Field Office, U.S. Fish and Wildlife Service, P.O. Box 491, Boqueron, Puerto Rico 00622. Information received in response to this notice of review will be available for public inspection by appointment, during normal business hours, at the same address in Clemson, South Carolina, and at Cabo Rojo National Wildlife Refuge, Ecological Service Office, Carr. 301, Km. 5.1, Bo. Corozo, Boquerón, Puerto Rico, for the other seven species.

Under the Act (16 U.S.C. 1533 et seq.), the Service maintains a list of endangered and threatened wildlife and plant species at 50 CFR 17.11 (for animals) and 17.12 (for plants) (collectively referred to as the List). Section 4(c)(2)(A) of the Act requires that we conduct a review of listed species at least once every five years. Then, on the basis of such reviews, under section 4(c)(2)(B), we determine whether or not any species should be removed from the List (delisted), or reclassified 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. The regulations at 50 CFR 424.21 require that we publish a notice in the Federal Register announcing those species currently under active review. This notice announces our active review of the following species that are currently federally listed as threatened: guajón and higo chumbo; and the following species currently federally listed as endangered: Puerto Rican parrot, Puerto Rican plain pigeon, red-cockaded woodpecker, Puerto Rican boa, Virgin Islands tree boa, and Adiantum vivesii.

The List is found in 50 CFR 17.11 (wildlife) and 17.12 (plants) and is also available on our Internet site at​wildlife.html#Species. Amendments to the List through final rules are published in the Federal Register.

What Information Is Considered in the 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 species;

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 methods.Start Printed Page 53808

Definitions Related to This Notice

The following definitions are provided to assist those persons who contemplate submitting information regarding the species being reviewed:

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 existence.

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 This Review?

If we find that there is new information concerning any of these eight 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); or (c) delist the species. If we determine that a change in classification is not warranted, then these species will remain on the List under their current status.

Public Solicitation of New Information

We request any new information concerning the status of these eight species. See “What information is considered in the review?” heading for specific criteria. Information submitted should be supported by 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. Our practice is to make comments, including names and home addresses of respondents, available for public review. Individual respondents may request that we withhold their home addresses from the supporting record, which we will honor to the extent allowable by law. There also may be circumstances in which we may withhold from the supporting record a respondent's identity, as allowable by law. If you wish us to withhold your name and/or address, you must state this prominently at the beginning of your comment. We will not consider anonymous comments, however. We will make all submissions from organizations or businesses, and from individuals identifying themselves as representatives or officials of organizations or businesses, available for public inspection in their entirety.
