We, the U.S. Fish and Wildlife Service (Service), in cooperation with the State of Alaska, propose to establish a nonessential experimental population of wood bison in central Alaska, in accordance with section 10(j) of the Endangered Species Act of 1973, as amended. This proposal, if made final, would also establish provisions under which wood bison in Alaska would be managed. We are seeking comments on this proposal and on our draft environmental assessment, prepared pursuant to the National Environmental Policy Act of 1969, as amended, which analyzes the potential environmental impacts associated with the proposed reintroduction.
