{"abstract":"We, the U.S. Fish and Wildlife Service (Service), revise the critical habitat designation for the contiguous U.S. distinct population segment (DPS) of the Canada lynx (Lynx canadensis) under the Endangered Species Act of 1973, as amended (Act). In total, approximately 14,030 square miles (36,340 square kilometers) in Colorado, Idaho, Montana, and Washington, fall within the boundaries of the revised critical habitat designation. This revision fulfills our obligations under a settlement agreement to address issues raised by the District Court of Montana regarding our 2014 final critical habitat designation.","action":"Final
