Bureau of Land Management Maps of Oregon, 1944-1993

Historical Note:

The United States Bureau of Land Management was formed in 1946 from the merger of the General Land Office and the United States Grazing Service. The Bureau of Land Management is in charge of administering over 245 million acres of public land, most of which is located throughout the 12 western states. The Bureau's mission is to sustain the health, diversity, and productivity of America's public lands for the use and enjoyment of present and future generations, which also includes managing the lands for energy development, livestock grazing, timber harvesting, and recreation. In Oregon, the western region is characterized by 2 million acres of checkerboard timberland ownership which is considered some of the most productive forests in the world, while the eastern Oregon portion of their ownership is known for large basin and range topography in semi-arid landscapes benefiting livestock grazing and range land habitat.

The Bureau of Land Management manages the Oregon and California Railroad Revested Lands (O&C Lands) in western Oregon. These lands (approximately 2.6 million acres) were originally granted to the Oregon & California Railroad for development of a railroad between Portland, Oregon, and San Francisco, California. The lands were reconveyed to the federal government in 1916 and have been managed by BLM since 1937.
