Revised Critical Habitat for the Contiguous United States Distinct Population Segment ofthe Canada Lynx (Lynx canadensis): Proposed rule.

We, the U.S. Fish and Wildlife Service (Service), propose to revise designated critical habitat for the contiguous United States distinct population segment of the Canada lynx (Lynx canadensis) (lynx) under the Endangered Species Act of 1973, as amended (Act). In the contiguous United States, the lynx generally inhabits cold, moist boreal forests. Approximately 42,753 square miles (mi\2\) (110,727 square kilometers (km\2\)) fall within the boundaries of the proposed revised critical habitat designation. The proposed revised designation would add an additional 40,913 mi\2\ (105,959 km\2\) to the existing critical habitat designation of 1,841 mi\2\ (4,768 km\2\). The proposed revised critical habitat is located in Boundary County, Idaho; Aroostook, Franklin, Penobscot, Piscataquis, and Somerset Counties in Maine; Cook, Koochiching, Lake, and St. Louis Counties in Minnesota; Flathead, Glacier, Granite, Lake, Lewis and Clark, Lincoln, Missoula, Pondera, Powell, Teton, Gallatin, Park, Sweetgrass, Stillwater, and Carbon Counties in Montana; Chelan and Okanogan Counties in Washington; and Park, Teton, Fremont, Sublette, and Lincoln Counties in Wyoming.
