Fish and Wildlife Service declines to list 
California's midvalley fairy shrimp

WASHINGTON (01/30/04) -- The U.S. Fish and Wildlife Service has decided against listing the the midvalley fairy shrimp as an endangered under the Endangered Species Act. The small crustacean is found in shallow seasonal wetlands known as vernal pools in Sacramento, Solano, Contra Costa, San Joaquin, Merced, Madera, Fresno and Yolo counties in California’s Central Valley.

The Services's decision comes in response to a petition – filed in August 2001 by the Center for Biological Diversity and VernalPools.Org – to list the midvalley fairy shrimp as endangered. 

“The Service has commissioned new survey efforts and will continue to review any new information concerning the status of the midvalley fairy shrimp,” said Wayne White, field supervisor of the Sacramento Fish and Wildlife Office. “The information will help us monitor and encourage the conservation of the species.”

The Service said from what it knows of the current range and distribution of the species, the midvalley fairy shrimp is well represented on protected lands and in areas with little or no current threat. Additionally, existing regulatory mechanisms under the California Environmental Quality Act, the Clean Water Act, and the ESA – while not directly applied to the midvalley fairy shrimp – are likely to moderate the rate and extent of habitat loss for this species. As a result of these factors, the Service finds that the species is not in danger of extinction in the foreseeable future.

A complete description of the Service’s finding on the midvalley fairy shrimp appears in the January 26, 2004, Federal Register, pages 3592–3598 [TEXT] [PDF].
