Start Preamble


Fish and Wildlife Service, Interior.


Notice of initiation of reviews; request for information.


We, the U.S. Fish and Wildlife Service (Service), are initiating 5-year status reviews of 15 species under the Endangered Species Act of 1973, as amended (Act). We conduct these reviews to ensure that the classification of species as threatened or endangered on the Lists of Endangered and Threatened Wildlife and Plants is accurate. A 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, we must receive your comments or information on or before June 8, 2010. However, we will continue to accept new information about any listed species at any time.

Under the Act (16 U.S.C. 1531 et seq.), we maintain lists of endangered and threatened wildlife and plant species in the Code of Federal Regulations (CFR) at 50 CFR 17.11 (for wildlife) and 17.12 (for plants) (collectively referred to as the List). The List is also available on our Internet site at​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 any species should be removed from the List (delisted), or reclassified from endangered to threatened or from threatened to endangered. If we consider delisting a species, we must support the action by the best scientific and commercial data available. We must consider if these 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 make amendments to the List through final rules published in the Federal Register.

Our 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 15 species currently listed as endangered: Bariaco (Trichilia triacantha), Calyptranthes thomasiana (no common name), capá rosa (Callicarpa ampla), Cook's holly (Ilex cookii), Chamaecrista glandulosa var. mirabilis (no common name), chupacallos (Pleodendron macranthum), Vahl's boxwood or diablito de tres cuernos (Buxus vahlii), erubia (Solanum drymophilum), Myrcia paganii (no common name), nogal (Juglans jamaicensis), palo de nigua (Cornutia obovata), palo de Ramón (Banara vanderbiltii), uvillo (Eugenia haematocarpa), Puerto Rican nightjar or guabairo (Caprimulgus noctitherus), and white-necked crow (Corvus leucognaphalus).

What Information Do We Consider in a 5-Year 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.


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.

What Could Happen as a Result of This Review?

If we find that there is new information concerning any of these 15 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 Start Printed Page 18233from 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.

Request for New Information

To do any of the following, contact Marelisa Rivera at the address or phone number provided under ADDRESSES:

(a) To get more information on a species,

(b) To submit information on a species, or

(c) To review information we receive, which will be available for public inspection by appointment, during normal business hours, at the listed address.

We request any new information concerning the status of these 15 species. See “What Information Do We Consider in a 5-Year 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.

Public Availability of Comments

Before including your address, phone number, e-mail address, or other personal identifying information in your comment, you should be aware that the entire comment—including your personal identifying information—may be made publicly available at any time. While you can ask us in your comment to withhold your personal identifying information from public review, we cannot guarantee that we will be able to do so.
