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.

74 Fed. Reg. 16232 / Vol. 74, No. 67 / Thursday, April 9, 2009 / DEPARTMENT OF THE INTERIOR / Fish and Wildlife Service / Endangered and Threatened Wildlife and Plants; Recovery Plan for the Rio Grande Silvery Minnow (Hybognathus amarus)/ Notice of document availability: draft amendment and supplement to the 2007 Draft revised recovery plan for Rio Grande Silvery Minnow.

SUMMARY: We, the U.S. Fish and Wildlife Service (Service), announce the availability of an amendment and supplement to our draft revised Recovery Plan (Recovery Plan) for the Rio Grande silvery minnow (Hybognathus amarus) under the Endangered Species Act of 1973, as amended (Act). The species currently inhabits the Rio Grande in New Mexico and has been introduced to the Big Bend area of Texas. This amendment and supplement consist of revised draft recovery criteria and a population viability assessment (PVA, or draft Appendix H), respectively. We invite public review and comment on these documents. After review we will incorporate the documents into the Final Recovery Plan (the PVA as Appendix H).

One of America’s most critically endangered species, the Rio Grande silvery minnow (Hybognathus amarus), began to face a brighter future on December 17, 2008, with the release of more than 430,000 hatchery-raised fish into former habitat in the Big Bend region of west Texas.  The U.S. Fish and Wildlife Service plans to release additional fish there over the next four years to establish an experimental, self-sustaining wild population in the lower Rio Grande.  Photo (by Aimee Roberson) and caption info from FWS.
