Endangered and Threatened Wildlife and Plants; Designation of Critical Habitat for Mount Charleston Blue Butterfly (Plebejus shasta charlestonensis)

Samenvatting

We, the U.S. Fish and Wildlife Service, propose to designate critical habitat for the Mount Charleston blue butterfly (Plebejus shasta charlestonensis) under the Endangered Species Act. In total, approximately 5,561 acres (2,250 hectares) are being proposed for designation as critical habitat. The proposed critical habitat is located in the Spring Mountains of Clark County, Nevada. If we finalize this rule as proposed, it would extend the Act's protections to this species' critical habitat. We also announce the availability of a draft economic analysis of the proposed designation of critical habitat for the Mount Charleston blue butterfly.
