Removal of 23 Extinct Species From the Lists of Endangered and Threatened Wildlife and Plants; Ivory-Billed Woodpecker

We, the U.S. Fish and Wildlife Service (Service), propose to designate critical habitat for the federally endangered Southern Sierra Nevada distinct population segment (DPS) of fisher (Pekania pennanti) under the Endangered Species Act of 1973, as amended (Act). In total, we propose to designate approximately 554,454 acres (ac) (224,379 hectares (ha)) in six units in California as critical habitat for the Southern Sierra Nevada DPS of fisher. We also announce the availability of a draft economic analysis of the proposed critical habitat designation.
