The National Wilderness Preservation System is comprised of wilderness areas managed by the Bureau of Land Management, Fish and Wildlife Service, Forest Service and National Park Service. The dataset available here was created by mining and combining the best available data from these federal agencies into a single dataset representative of the entire wilderness system. The Wilderness Institute at the University of Montana's College of Forestry and Conservation, through a unique partnership with these four agencies, maintains and serves this public dataset online in both map service and shapefile format.
Shapefiles are for use by those with GIS mapping software and expertise using and manipulating geographic data. You can download a shapefile of the entire NWPS
or select a wilderness below to download just the boundary for that area. You can also connect to our public wilderness feature service
and map service
(you may need to omit "rest" when adding from ArcGIS). Feature level metadata is available for boundaries that have been updated since 7/22/2009. This Excel spreadsheet
provides the date of last update and contact information for the person from which the data was obtained. Boundaries are generally reobtained from the managing agencies and updated within this dataset yearly.
There are no wilderness areas (yet) that begin with the letter X.
