National Conservation Lands, formally known as the National Landscape Conservation System, is a 35-million-acre (140,000 km2) collection of lands in 873 federally recognized areas considered to be the crown jewels of the American West. These lands represent 10% of the 258 million acres (1,040,000 km2) managed by the Bureau of Land Management (BLM). The BLM is the largest federal public land manager and is responsible for over 40% of all the federal public land in the nation. The other major federal public land managers include the US Forest Service (USFS), National Park Service (NPS), and the US Fish and Wildlife Service (USFWS). Over the years, the Bureau of Land Management has had to adjust its approach to public land management to fit the changing needs of the nation. The BLM historically has managed lands under its jurisdiction for extractive uses, such as mining, logging, grazing, and oil and gas production. In 1983, Congress acknowledged the value of watersheds, wildlife habitat, recreation, scenery, scientific exploration and other non-extractive uses with the designation of the first BLM-managed wilderness area - the Bear Trap Canyon unit of the Lee Metcalf Wilderness in Montana. In 1996, President Clinton underscored non-extractive priorities on BLM lands when he established the first national monument to be administered by the BLM - the Grand Staircase-Escalante National Monument in southern Utah. With this and several similar designations, a new focus emerged that would become part of how the agency looks at the land it manages: the protection of special areas where conservation and restoration of the landscape and its biological or cultural resources is the overriding objective. The Bureau of Land Management's National Landscape Conservation System, better known as the National Conservation Lands, was created in 2000 with the mission to conserve, protect, and restore these nationally significant landscapes that have outstanding cultural, ecological, and scientific values for the benefit of current and future generations. There are ten different federal conservation designations for the units that make up the National Conservation Lands:
