This biological assessment (BA) documents the potential effects of existing Forest Service (FS) Land and Resource Management Plans (LRMPs), or 'Forest Plans' and Bureau of Land Management (BLM) Land Use Plans (LUPs) on the Canada Lynx (Lynx canadensis), hereafter referred to as the lynx. LRMPs and LUPs are collectively referred to as 'Plans' in this document. In a Federal Register notice on July 8, 1998, the U.S. Fish and Wildlife Service (FWS) proposed a distinct population segment of the lynx within 16 states to be listed as threatened (U.S. Fish and Wildlife Service 1998a). This BA evaluates 57 LRMPs and 56 LUPs in 13 of these states: Maine, New Hampshire, Vermont, Michigan, Wisconsin, Minnesota, Colorado, Wyoming, Utah, Montana, Idaho, Oregon and Washington.
