P.L. 73-482 (June 28, 1934) provides for the regulation of grazing on the public lands (excluding Alaska) to improve rangeland conditions and stabilize the western livestock industry. The law initially permitted 80 million acres of previously unreserved public lands of the United States to be placed into grazing districts to be administered by the Department of the Interior. As amended, the law now sets no limit on the amount of lands in grazing districts. There are currently approximately 150 million acres in grazing districts.
