The U.S. Fish and Wildlife Service (Service) today announced the availability of the draft economic analysis for a proposed rule to designate critical habitat for Sierra Nevada bighorn sheep (Ovis canadensis californiana), a federally threatened species. Areas proposed as critical habitat include portions of Tuolumne, Mono, Fresno, Inyo, and Tulare counties in California. The draft economic analysis estimates potential costs for conservation activities to be approximately $26.7 million and costs associated solely with the designation of critical habitat to be approximately $135,000 over a 20-year period in areas proposed as critical habitat.

“In releasing the analysis, the Service also reopened the public comment period on the proposed critical habitat designation. Comments and information previously submitted on the proposal to designate critical habitat for Sierra Nevada bighorn sheep between July 25, 2007, and November 23, 2007, need not be resubmitted,” said Bob Williams Field Supervisor for the Nevada Fish and Wildlife Office. “Comments already received will be incorporated into the public record and will be fully considered in preparation of the final rule.”

Critical habitat is a term of the Endangered Species Act that identifies geographic areas containing features essential for the conservation of a threatened or endangered species, and which may require special management considerations or protection. Designation of critical habitat does not affect land ownership, establish a refuge or preserve, and has no impact on private landowners taking actions on their land that do not require Federal funding or permits.

The proposed critical habitat includes open upland, montane, and alpine habitats with rocky areas along the eastern slope of the Sierra Nevada Mountains from about 4,000 feet to approximately 14,500 feet. Of the proposed critical habitat, 416,407 acres, occurs on federally managed lands with the remaining 1,005 acres, under private ownership and 165 acres managed by local government.

When specifying an area as critical habitat, the Endangered Species Act requires the Service to consider economic and other relevant impacts of the designation. If the benefits of excluding an area outweigh the benefits of designating it, the Secretary may exclude an area from critical habitat, unless that would jeopardize the existence of a threatened or endangered species.
