The Bureau of Land Management, an agency of the US Department of the Interior, was officially established in 1946, though the work of its mission dates back to 1812 with the General Land Office, which merged with the US Grazing Service to form the current agency. BLM administers a tenth of America's public lands, more than any other government agency. The mission of BLM is "managing public land for multiple uses while conserving natural, historical, and cultural resources. In the language of FLPMA, the BLM is to administer public lands “on the basis of multiple use and sustained yield” of resources." Multiple uses include: "renewable energy development (solar, wind, other); conventional energy development (oil and gas, coal); livestock grazing; hardrock mining (gold, silver, other), timber harvesting; and outdoor recreation (such as camping, hunting, rafting, and off-highway vehicle driving)."
