Federal Land Policy Management Act, or FLPMA (Pub.L. 94-579), is a United States federal law that governs the way in which the public lands administered by the Bureau of Land Management are managed. The law was enacted in 1976 by the 94th Congress. In the FLPMA, Congress recognized the value of the public lands, declaring that these lands would remain in public ownership. Congress used the term "multiple use" management, defined as "management of the public lands and their various resource values so that they are utilized in the combination that will best meet the present and future needs of the American people." It is found in the United States Code under Title 43.
