The Bureau of Land Management (BLM) administers 247.3 million acres of public lands in the United States, which is one-eighth of the country's total landmass. The BLM was formed in 1946 by combining the General Land Office and Grazing Service to more efficiently manage federal lands and resources. It focuses on managing public lands for uses like energy development, recreation, grazing, and conservation. Over time, the BLM has grown to over 10,000 employees and generates billions of dollars each year from activities on its lands.
