U.S. Fish and Wildlife Service Announces Availability of the Final Revised Recovery Plan for the Pallid Sturgeon
For Immediate Release
March 3, 2014
DENVER — The U.S. Fish and Wildlife Service (Service) is announcing the availability of the Pallid Sturgeon Revised Recovery Plan (Plan). The Pallid Sturgeon (Scaphirhynchus albus) is a bottom-feeding fish considered to be a relic of the dinosaur era, which historically occupied the Missouri and Yellowstone rivers in Montana downstream to the Missouri-Mississippi confluence and the Mississippi River possibly from near Keokuk, Iowa, downstream to New Orleans, Louisiana. The species is listed as endangered under the Endangered Species Act of 1973 (Act).
Pallid Sturgeon are an important indicator of the health of several of America's largest rivers, and represent a unique piece of America's natural history, with fossil ancestors dating back over 70 million years. The draft revised plan summarizes and updates the available information on the species life history needs, reevaluates the threats to the species, and identifies recovery efforts.
The U.S. Fish and Wildlife Service originally drafted the recovery plan in 1993 as an outline of the steps necessary to recover the imperiled fish, which dates back to the prehistoric era. Revisions to the recovery plan will allow the Service and its conservation partners to better address threats such as habitat destruction to the imperiled fish.
The objective of a recovery plan is to provide a framework for the recovery of a species so that protection under the Act is no longer necessary. A recovery plan includes scientific information about the species and provides criteria and actions necessary for the Service to be able to remove it from the Federal List of Endangered and Threatened Wildlife and Plants. Recovery plans do not regulate federal agencies or their partners, but recovery plans are often adopted by federal agencies as sound environmental policy.
"In order to keep pace with the rapidly changing and heavily used rivers the pallid sturgeon calls home, we updated its recovery plan to better meet the conservation challenges," said Noreen Walsh, Mountain-Prairie regional director. "It's our goal to conserve and protect this 'living dinosaur' from extinction for future generations of Americans."
A number of threats to the pallid sturgeon's habitat have complicated the recovery of this freshwater fish. Human modification of its river habitat such as river channelization, impoundment, and altered flow regimes are in part responsible. Degraded water quality and disease are among other factors proving challenges to recovery of the pallid sturgeon.
