The Bureau of Land Management's (BLM) mission is to sustain the health, diversity, and productivity of America’s public lands for the multiple use and enjoyment of present and future generations.
The BLM manages one in every 10 acres of land in the United States, and approximately 30 percent of the Nation’s minerals. These lands and minerals are found in every state in the country and encompass forests, mountains, rangelands, arctic tundra, and deserts.
Congress tasked the BLM with a mandate of managing public lands for a variety of uses such as energy development, livestock grazing, recreation, and timber harvesting while ensuring natural, cultural, and historic resources are maintained for present and future use.
Most BLM public lands are located in these 12 western states: Alaska, Arizona, California, Colorado, Idaho, Montana, Nevada, New Mexico, Oregon, Utah, Washington, and Wyoming. BLM headquarters is located in Washington, DC. Other locations -- https://www.blm.gov/about/what-we-manage
