Designation of Critical Habitat for Four Distinct Population Segments of the Foothill Yellow-Legged Frog

We, the U.S. Fish and Wildlife Service (Service), propose to designate critical habitat for four distinct population segments (DPSs) of the foothill yellow-legged frog (Rana boylii) under the Endangered Species Act of 1973, as amended (Act). In total, approximately 760,071 acres (307,590 hectares) in California fall within the boundaries of the proposed critical habitat designation. We also announce the availability of an economic analysis of the proposed designation of critical habitat for four DPSs.
