Livestock grazing is the most extensive commercial use of public lands in the United States. The two largest categories of public lands are the national forests, managed by the United States Forest Service, and the public lands managed by the Bureau of Land Management (BLM). Grazing is authorized on approximately 159 million acres, or about 90 percent, of the 177 million acres of BLM lands in the western United States.(1) The 18 million acres of BLM lands that are not used for livestock grazing consist mostly of lands that cannot be grazed because of lack of forage, lack of ...
