Endangered and Threatened Wildlife and Plants; Revision of a Nonessential Experimental Population of Black-Footed Ferrets (Mustela nigripes) in the Southwest

Abstract

We, the U.S. Fish and Wildlife Service (Service and USFWS), propose to revise the regulation for the nonessential experimental population of the black-footed ferret (Mustela nigripes) (ferret) in Arizona. We established the Aubrey Valley Experimental Population Area (AVEPA) in 1996 in accordance with section 10(j) of the Endangered Species Act of 1973, as amended (ESA). This proposed rule would allow the reintroduction of ferrets across a larger landscape as part of a nonessential experimental population and include the AVEPA within a larger "Southwest Experimental Population Area" (SWEPA), which includes parts of Arizona and identified contiguous Tribal land in New Mexico and Utah. This proposed revision provides a framework for establishing and managing reintroduced populations of ferrets that will allow greater management flexibility and increased landowner cooperation. The best available data indicate that reintroduction of the ferret into suitable habitat in the proposed SWEPA is biologically feasible and will promote the conservation of the species. We are seeking comments on this proposal and on our draft environmental assessment (EA) that analyzes the potential environmental impacts associated with the proposed regulatory revisions.
