The Bureau of Land Management (BLM) is an agency within the United States Department of the Interior which administers America's public lands, totaling approximately 264 million acres (1,070,000 km²) or one-eighth of the landmass of the country. Most public lands are located in western states. With approximately 9,000 permanent employees, and over 1,000 more temporary, this works out to over 26,000 acres (105 km²) per employee. Its budget is nearly 1 billion dollars for 2007 ($3.50 per acre, $3.30 per person).

The BLM's stated mission is to sustain the health, diversity and productivity of the public lands for the use and enjoyment of present and future generations.
