national parks National Park Service hundreds of other federally managed wilderness areas western states protected state military states
There are 63 national parks, which are managed by the National Park Service, and hundreds of other federally managed parks, forests, and wilderness areas, managed by the National Park Service and other agencies. Altogether, about 28% of the country's land area is publicly owned and federally managed, primarily located in the western states. Most of this land is protected, though some is leased for oil and gas drilling, mining, logging, or cattle ranching, and less than one percent of it is used for military purposes.
