Endangered and Threatened Wildlife and Plants; Establishment of a Nonessential Experimental Population of Black-footed Ferrets in Wyoming

We, the U.S. Fish and Wildlife Service (Service), in coordination with the State of Wyoming and other partners, will reestablish additional populations of the black-footed ferret (Mustela nigripes), a federally listed endangered mammal, into prairie dog (Cynomys spp.) occupied habitat in Wyoming and classify any reestablished population as a nonessential experimental population (NEP) under section 10(j) of the Endangered Species Act of 1973, as amended (Act). This final rule establishes the NEP area and provides for allowable legal incidental taking of the black-footed ferret within the defined NEP area. The best available data indicate the reintroduction of black-footed ferrets to Wyoming is biologically feasible and will promote conservation and recovery of the species. This NEP area and two previously designated NEPs in Wyoming collectively cover the entire State of Wyoming and provide consistent management flexibility Statewide. We are also amending the historical range column for the species within the List of Endangered and Threatened Wildlife (List) to include Mexico; the historical range information in the List is informational, not regulatory.
