The Bureau of Land Management's National Conservation Lands, also known as the National Landscape Conservation System, contain some of the West's most spectacular landscapes. It includes over 886 federally recognized areas and approximately 27 million acres that include Wilderness areas.
The BLM in Oregon and Washington manages 127 different National Conservation Lands which include two National Monuments, one Cooperative Management and Protection Area, one legislated Outstanding Natural Area, 86 Wilderness Study Areas, 25 Wild & Scenic Rivers (the most of any BLM state), two National Scenic Trails, two National Historic Trails and nine Wilderness Areas.
Wilderness is Congressionally-designated pieces of land that is managed in accordance with the Wilderness Act of 1964 to "...secure for the American people of present and future generations the benefits of an enduring resource of wilderness." Wilderness areas are places where natural processes take precedent; areas managed so that nature remains substantially unchanged by human use. Rugged trails provide the only access into wilderness, and travel is restricted to foot or horseback.
