This is an area larger than the state of California or Iraq. In Alaska, there are 58,182,216 acres (235,455 km²) of wilderness. This represents about 56% of the wilderness area in the United States. The National Park Service (NPS) has oversight of 44 million acres (180,000 km²) of wilderness at 47 locations. The U.S. Fish and Wildlife Service has responsibility for nearly 21 million acres (85,000 km²) in 71 areas. The Bureau of Land Management (BLM) oversees more than 6.5 million acres (26,000 km²) at 177 unique sites. The Department of Agriculture, the U.S. Forest Service oversees nearly 35 million acres (142,000 km²) of wilderness areas in 407 areas. Some wilderness areas are managed by multiple agencies, so the above totals exceed the actual number of units (680) in the system. In addition, some of the 47 NPS areas with wilderness have multiple units designated as such (for example, Lake Mead National Recreation Area).
Some areas are designated wilderness by state or tribal governments. These are not federal parks. See List of U.S. state and tribal wilderness areas.
