[Federal Register: March 20, 2008 (Volume 73, Number 55)] [Notices] [Page 14995-14997] From the Federal Register Online via GPO Access [wais.access.gpo.gov] [DOCID:fr20mr08-54] ======================================================================= ----------------------------------------------------------------------- DEPARTMENT OF THE INTERIOR Fish and Wildlife Service [FWS-R2-ES-2008-N0023, 21012-11130000-C4] Endangered and Threatened Wildlife and Plants; 5-Year Reviews of 28 Southwestern Species AGENCY: Fish and Wildlife Service, Interior. ACTION: Notice of reviews. ----------------------------------------------------------------------- SUMMARY: We, the U.S. Fish and Wildlife Service (Service), announce 5- year reviews of 28 southwestern species listed under the Endangered Species Act of 1973 (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 is accurate. The 5-year review is an assessment of the best scientific and commercial data available at the time of the review. DATES: To allow adequate time to conduct this review, information submitted for our consideration must be received on or before June 18, 2008. However, we will continue to accept new information about any listed species at any time. ADDRESSES: Information submitted on these species should be sent to the Service at the addresses listed under ``Public Comments'' in the SUPPLEMENTARY INFORMATION section. Information received in response to this notice of review will be available for public inspection by appointment, during normal business hours, at the same addresses. FOR FURTHER INFORMATION CONTACT: Contact the appropriate office named in ``Public Comments'' for species-specific information. 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 28 species since their original listings as either endangered (Arizona hedgehog cactus, Big Bend gambusia, Brady pincushion cactus, Clear Creek gambusia, Comal Springs dryopid beetle, Comal Springs riffle beetle, fountain darter, Kearney blue star, Leon Springs pupfish, Peck's Cave amphipod, San Marcos gambusia, Sonoran pronghorn, Socorro isopod, Socorro springsnail, south Texas ambrosia, southwestern willow flycatcher, Terlingua Creek cat's- eye, Texas ayenia, Texas blind salamander, Texas wild-rice, Tobusch fishhook cactus, Yaqui chub, and Yaqui topminnow) or threatened (beautiful shiner, Hinckley oak, San Marcos salamander, Sonora chub, and Yaqui catfish). 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 28 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.

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 28 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; (b) reclassify the species from threatened to endangered; 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.
