	Overview

The federal government owns roughly 640 million acres, more than a quarter of the land in the United States. Four federal agencies—the National Park Service (NPS), Fish and Wildlife Service (FWS), and Bureau of Land Management (BLM), all in the Department of the Interior (DOI), and the U.S. Forest Service (FS) in the Department of Agriculture—administer about 95% of those lands. No single law provides authority for these four agencies to acquire and/or disposal of lands. The extent to which each of the agencies has authority to acquire and dispose of land, and the nature of the authorities, varies considerably. Most notably, the BLM has relatively broad authority for both acquisitions and disposals. By contrast, the NPS has no general authority to acquire land to create new park units or to dispose of park lands. The FS authority to acquire lands is mostly limited to lands within or contiguous to the boundaries of a national forest. The agency has various authorities to dispose of land, but they are relatively constrained and infrequently used. The FWS has various authorities to acquire lands but no general authority to dispose of its lands. In general, the acquisition authorities are designed to allow federal agencies to acquire lands that could be viewed as benefitting from federal management. The disposal authorities generally are designed to allow federal agencies to dispose of land that is no longer required for a federal purpose, might be inefficient to manage, or might be chiefly valuable for another purpose. The Federal Land Policy and Management Act of 1976 (FLPMA; 43 U.S.C. Issues for Congress

Congress often faces questions on the adequacy of existing acquisition and disposal authorities; the nature, extent, and location of their use; the extent of federal land ownership overall; and the sources and levels of land acquisition funds, among other issues. The suitability of the acquisition and disposal authorities, and the extent and circumstances of their use by the agencies, forms the backdrop for congressional consideration of measures to establish, modify, or eliminate the use of authorities. In other cases, Congress directs a particular acquisition or disposal to facilitate the action. Congress also addresses acquisition and disposal policy in the context of deliberations on the role and goals of the federal government in owning and managing land generally. Acquisition Funding

Another set of issues pertains to the sources and levels of funds for land acquisition. For instance, the FWS has a mandatory source of funds for land acquisition through the Migratory Bird Conservation Fund, as discussed below. As another example, the BLM also has mandatory spending authorities that allow the agency to keep the proceeds of land sales and use these proceeds for subsequent acquisitions and other purposes. A principal FWS land acquisition authority is the Migratory Bird Conservation Act of 1929 (MBCA; 16 U.S.C. The MBCA authority is used frequently because of the availability of funding through the Migratory Bird Conservation Fund (MBCF, 16 U.S.C. In addition, the four federal land management agencies have different standing authorities for disposing of lands. In some cases, the proceeds may be used for specified land acquisition purposes. §1713(a)):
(1) such tract because of its location or other characteristics is difficult and uneconomic to manage as part of the public lands, and is not suitable for management by another Federal department or agency; or
(2) such tract was acquired for a specific purpose and the tract is no longer required for that or any other Federal purpose; or
(3) disposal of such tract will serve important public objectives, including but not limited to, expansion of communities and economic development, which cannot be achieved prudently or feasibly on land other than public land and which outweigh other public objectives and values, including, but not limited to, recreation and scenic values, which would be served by maintaining such tract in Federal ownership.
The federal government owns roughly 640 million acres, heavily concentrated in 12 western states. Four agencies—the National Park Service (NPS), Fish and Wildlife Service (FWS), and Bureau of Land Management (BLM) in the Department of the Interior, and the U.S. Forest Service (FS) in the Department of Agriculture—administer about 95% of those lands.
The extent to which each of these four federal agencies have authority to acquire and dispose of land varies considerably. The BLM has relatively broad authority for both acquisitions and disposals under the Federal Land Policy and Management Act of 1976 (FLPMA). The agency also has other authorities for disposing of land, including two laws that allow the agency to retain the proceeds for subsequent land acquisition, among other purposes, and a law that allows transfers to governmental units and other entities for public purposes. By contrast, the NPS has no general authority to acquire land to create new park units or to dispose of park lands. The FS authority to acquire lands is mostly limited to lands within or contiguous to the boundaries of a national forest. The agency has various authorities to dispose of land, but they are relatively constrained and infrequently used. The FWS has various authorities to acquire lands but no general authority to dispose of its lands. The agency frequently uses acquisition authority under the Migratory Bird Conservation Act of 1929 because of the availability of funding through the Migratory Bird Conservation Fund.
The nature of the acquisition and disposal authorities of the four federal agencies also varies. In general, the acquisition authorities are designed to allow the four agencies to bring into federal ownership lands that many contend could benefit from federal management. Disposal authorities generally are designed to allow agencies to convey land that is no longer needed for a federal purpose or that might be chiefly valuable for another purpose. Some of the authorities specify particular circumstances where they can be used, such as the conveyance of FS land for educational purposes and the disposal of BLM land for recreation and public purposes.
Congress often faces questions on the adequacy of existing acquisition and disposal authorities; the nature, extent, and location of their use; and the extent of federal land ownership overall. The current acquisition and disposal authorities form the backdrop for consideration of measures to establish, modify, or eliminate authorities, or to provide for the acquisition or disposal of particular lands. In some cases, Congress enacts bills to provide authority to acquire or dispose of particular parcels where no standing authority exists and, in other cases, to direct or facilitate land transactions. Congress also addresses acquisition and disposal policy in the context of debates on the role and goals of the federal government in owning and managing land generally, and it has considered broader measures to dispose of lands or to promote acquisition.
Other issues for Congress pertain to the sources and levels of funds for land acquisition. The Land and Water Conservation Fund (LWCF) is the primary source of funding for land acquisition. Congress has considered diverse measures related to the LWCF, such as legislation to make LWCF funding permanent and bills to direct LWCF monies to additional, nonacquisition purposes. Additionally, the FWS has the Migratory Bird Conservation Fund, an account with mandatory spending authority supported by revenue from three sources. The BLM also has mandatory spending authorities that allow the proceeds from land sales to be used for land acquisition, among other purposes.
