SUPPLEMENTARY INFORMATION:

Why is a 5-year review conducted?

Section 4(c)(2)(A) of the Act (16 U.S.C. 1531 et seq.) requires that we conduct a review of listed species at least once every 5 years. We are then, under section 4(c)(2)(B) and the provisions of subsections (a) and (b), to determine, on the basis of such a review, whether or not any species should be removed (delisted) from the List of Endangered and Threatened Wildlife and Plants (50 CFR 17.12), or reclassified from endangered to threatened (downlisted), or from threatened to endangered (uplisted).

The 5-year review is an assessment of the best scientific and commercial data available at the time of the review. Therefore, we are requesting submission of any new information (best scientific and commercial data) on the following 24 species since their original listings as either endangered (Arizona cliffrose, Attwater's prairie chicken, Bee Creek Cave harvestman, Bone Cave harvestman, Coffin Cave mold beetle, Gila topminnow, Knowlton's cactus, Kretschmarr Cave mold beetle, Large-fruited sand verbena, Mancos milkvetch, Nichol Turk's head cactus , Ouachita rock pocketbook, Sentry milkvetch, Texas snowbells, Tooth Cave pseudoscorpion, Tooth Cave spider, and Walker's manioc) or threatened (Chiricahua leopard frog, Devils River minnow, Loach minnow, New Mexico ridge-nosed rattlesnake, Pecos sunflower, San Francisco Peaks groundsel, and Spikedace). If the present classification of any of these species is not consistent with the best scientific and commercial information available, the Service will recommend whether or not a change is warranted in the Federal classification of that species. Any change in Federal classification would require a separate rule-making process.

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 the 24 species listed in Table 1.

What information is considered in the review?

A 5-year review considers all new information available at the time of the review. These reviews will consider 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 of Endangered and Threatened Wildlife and Plants, and improved analytical methods.

How are these species currently listed?

The List of Endangered and Threatened Wildlife and Plants (List) is found in 50 CFR 17.11 (wildlife) and 17.12 (plants). Amendments to the List through final rules are published in the Federal Register. The List is also available on our internet site at http://www.fws.gov/​endangered/​wildlife.html. In Table 1 below, we provide a summary of the listing information for the species under active review.

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 five following 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 the 24 species listed in Table 1 indicating 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) remove the species from the List. 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 the 24 species listed in Table 1. 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. Before including your address, phone number, e-mail address, or other personal identifying information in your comments, you should be aware that your 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.
