The BLM provides for land use, purchase, exchange, donation and sale; determines the boundaries of federal land; and maintains historic records for these ownership transactions. Land ownership transfer through purchase, exchange, donation and sale is an important component of the BLM’s strategy. Disposing (by sale or exchange) small, isolated and difficult to manage parcels improves the BLM’s overall ownership pattern which reduces costs associated with managing those parcels and reduces the potential risk of conflicts with adjacent landowners. Consolidated ownership patterns provide an efficient landscape for BLM managers and their planning and decision making processes for preservation, conservation values considered important to remain under the BLM jurisdiction. The bureau completes ownership transactions involving land and interests in land when such transactions are in the public interest and consistent with publicly-approved land use plans.
