Boundaries of declared wilderness areas in NSW under S.8 of the Wilderness Act 1987.

,Wilderness areas are federally-owned public lands managed by the federal government through four agencies, the Bureau of Land Management, Fish and Wildlife Service, Forest Service, and National Park Service. When the National Wilderness Preservation System started in 1964, only 54 wilderness areas were included. Since then, the system has grown nearly every year to include more than 800. The time component of this service is based on the year in which the wilderness was originally designated (additions may have occurred in subsequent years). Overall, however, only about 5% of the entire United States—an area slightly larger than the state of California— is protected as wilderness. Because Alaska contains just over half of America's wilderness, only about 2.7% of the contiguous United States—an area about the size of Minnesota—is protected as wilderness. To learn more about wilderness areas, visit Wilderness Connect, the authoritative source for wilderness information online. Wilderness Connect also publishes two other map resources:,,,Although wilderness areas are federally-owned, some areas contain non-federal parcels within their boundaries. Non-federal lands within some wilderness areas are included as part of this feature dataset as a separate layer. Termed inholdings or edgeholdings, these lands are privately-owned or owned by local governments, state governments or Indigenous Nations. Hundreds of inholdings and edgeholdings exist across the wilderness system. Generally, however, they are small compared to the size of the wilderness itself. Since the rules and regulations that apply to wilderness areas do not apply to these non-federally-owned parcels, it is important for wilderness visitors to know their location to avoid trespassing where access is not allowed. The owners of inholdings and edgeholdings can develop these parcels (as long as developments do not affect the character of the surrounding wilderness lands) and they retain special and limited access to them, sometimes, but not always, by motorized means.,

This data layer depicts the Wilderness and Proposed Wilderness that have been placed upon the lands and waters administered by the U.S. Fish and Wildlife Service (USFWS) in North America, U.S. Trust Territories and Possessions. These special areas, such as wilderness, are primarily designated by the U.S. Congress. The primary source for this information is the USFWS Wilderness program and the NWRS Realty program.

The Federal Land Policy and Management Act of 1976 (FLPMA) mandated by the Secretary of Interior to report to the President on the wilderness suitability of lands managed by the Bureau of land Management (BLM) by October 21, 1991. This report is the result of a comprehensive study of public lands in Idaho by the Bureau of Land Management regarding the suitability of these lands for wilderness designation. Summary, from the Idaho Wilderness Study Report dated 1991. For more information contact us at blm_id_stateoffice@blm.gov.

Areas that have been designated by Congress, Executive Order, Presidential Proclamation, or an Executive branch Department, excluding National Wilderness and National Wild & Scenic Rivers, with related details including the date of the designation, status of the final boundary description, authority, and land status case and document information.

This vector polygon dataset represents the current gross extent of Congressionally-designated wilderness for the National Park Service, Alaska Region. The Congressionally-designated wilderness boundaries defined in this dataset are external wilderness unit boundaries. They do not exclude lands (e.g. inholdings) that fail to meet the Alaska National Interest Lands Conservation Act (ANILCA) definition for "public lands" (i.e. Public Law 96-487, 94 Statute 2371, Title I, Section 102(3 A-C), December 1980).
