Public Land
From Wikipedia
https://en.wikipedia.org/wiki/Public_land
In the United States, governmental entities including cities, counties, states, and the federal government all manage land which are referred to as either public lands or the public domain. The majority of public lands in the U.S. are held in trust for the American people by the federal government and managed by the Bureau of Land Management (BLM), U.S. National Park Service, Bureau of Reclamation, or Fish and Wildlife Service under the Department of the Interior, or by the U.S. Forest Service under the Department of Agriculture. Other federal agencies that manage public lands include the National Oceanic and Atmospheric Administration and the U.S. Department of Defense.
