Designation of Critical Habitat for the Southern Selkirk Mountains Population of Woodland Caribou (Rangifer tarandus caribou): Proposed rule; availability of supplementary documents and announcement of public hearing.

We, the U.S. Fish and Wildlife Service (Service), announce the reopening of the comment period on our November 30, 2011, proposed rule to designate critical habitat for the southern Selkirk Mountains population of woodland caribou (Rangifer tarandus caribou) under the Endangered Species Act of 1973, as amended (Act). We also announce the availability of a draft economic analysis of the proposed designation and an amended required determinations section of the proposal. We are reopening the comment period to allow all interested parties an opportunity to comment simultaneously on the proposed rule, the associated draft economic analysis, and the amended required determinations section. We will also hold a public informational session and hearing (see DATES and ADDRESSES).
