BLM's National Conservation Lands, formally National Landscape Conservation System (NLCS), offers some of the most remarkable landscapes found on the public lands in the American West. Many of these places have already received special recognition and protection through congressional or presidential conservation designations. The National Conservation Lands adds to these designations by focusing on the opportunities and management needs of these national treasures. Managing these areas is part of the BLM's multiple-use mission to sustain the health of the public lands for present and future generations. The following units are part of the National Conservation Lands in Montana and the Dakotas:
In addition to these units, Montana also has 39 wilderness study areas.
