florida gators... never threatened!

If you ain't a Gator, you should be! Alligators (and endangered crocs) are important indicator species atop their food chains, with sensitivity to pollution and pesticides akin to humans. See ESA blawg. Gator blood could be our pharmaceutical future, too. See ESA musing.


Follow the truth.

"This institution will be based on the illimitable freedom of the human mind. For here we are not afraid to follow truth wherever it may lead, nor to tolerate any error so long as reason is left free to combat it." -- Thomas Jefferson to William Roscoe, December 27, 1820.

73 Fed. Reg. 14,995 (March 20, 2008)(Department of the Interior, Fish and Wildlife Service; Endangered and Threatened Wildlife and Plants; 5-Year Reviews of 28 Southwestern Species)

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.

COMMENTARY: The species include: Arizona hedgehog cactus, Beautiful shiner, Big Bend gambusia, Brady pincushion cactus, Clear Creek gambusia, Comal Springs dryopid beetle, Comal Springs riffle beetle, Fountain darter, Hinckley oak, Kearney blue star, Leon Springs pupfish, Peck’s Cave amphipod, San Marcos gambusia, San Marcos salamander, Sonora chub, 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 catfish, Yaqui chub, and Yaqui topminnow.

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.
