Maps: Bureau of Land Management Holdings

A vast amount of this nation's shared natural heritage—245 million acres—is owned and administered by the Bureau of Land Management (BLM). BLM lands represent many types of terrain—including canyon country, Arctic tundra, sage-grass steppes, mountains, and ancient forests—that serve as important habitat for fish and big game such as antelope, bison, bighorn sheep, and elk. The BLM's National Landscape Conservation System, established by Congress in 2009, safeguards 27 million acres, but these lands are only a small fraction of the agency's ecologically significant holdings.

The following maps show the land under BLM's purview.
