Nationally, the NLCS contains more than 800 units totaling more than 25 million acres. Idaho BLM has 74 NLCS units that encompass approximately 3 million acres of public land. These units include the Snake River Birds of Prey National Conservation Area, Craters of the Moon National Monument, four National Historic Trails, a National Scenic Trail, and 66 wilderness study areas. Idaho’s NLCS areas are described below.
Idaho’s public lands have many other exceptional areas that are highly valued for their scenic and recreational values. However, they are not part of the NLCS because they have not been nationally designated by either the President or Congress. Information about these outstanding places, which include river systems, lakes, recreation areas, and unique habitats, is found under recreation, rivers, and field offices.
