  1. Footnote for Agency and State or Region.A wilderness area can exists in more than one state or region and/or is managed by more than one agency. In these cases, if unit or regional acreages and total acreages are shown, they will differ and, depending on the sort criteria selected, units of the same wilderness may not be listed or may not be listed consecutively. See footnote 2 below. Year may also differ. See footnote 3 below. Press enter to return to previous content.
  2. Footnote for Acreage Operator. Total acreage is the current acreage of the entire wilderness. This measurement will include all acres of a wilderness, regardless of any state, agency, region or year selections you make. Unit acreage is wilderness acreage existing in a single state managed by a single agency. Unit acreage should not be confused with administrative unit acreage, a further breakdown of acreage that differs by agency. Regional acreage, if shown, is wilderness acreage found within the Fish and Wildlife Service or Forest Service region selected. Since almost 25% of wilderness areas have acreage designated under multiple laws, search the wilderness law library, see footnote 4 below for link, by wilderness, year or public law for a breakdown of how a wilderness area has grown over time. Press enter to return to previous content.
  3. Footnote for Designation Year. Designation indicates the year that a wilderness was designated by Congress. For multi-managed wilderness areas, this represents the year in which each agency started managing the area, and may be different depending on the agency. For example, the Domeland Wilderness was originally designated in 1964, but at that time was managed only by the Forest Service. The Bureau of Land Management did not begin managing the area until its acreage was added in 1994. Similarly, for wilderness areas with acreage in more than one state, this represents the year the acreage was first designated in that state. For example, while the Absaroka-Beartooth Wilderness was originally designated in 1978 in Montana, its Wyoming portion did not come into existence until 1984.

Exploring Wilderness Data

The Federal laws that established individual wilderness units—beginning with the Wilderness Act of 1964 and including all subsequent wilderness legislation—are the legally definitive sources for wilderness names, locations, original acreages, and dates of designation.

Wilderness Connect’s National Wilderness Preservation System database, searchable using the form above, is grounded in the following publication, which compiled legislated acreages for all designated wilderness areas:

Current acreage figures reflect the sum of administrative unit acreages as reported by each managing agency through annual realty reports.
