This data layer consists of National Wilderness Preservation System areas in the United States, Puerto Rico, and the U.S. Virgin Islands. The map layer was created by combining the best available data from the federal agency responsible for administration of a given wilderness area. Where larger scale data could not be obtained, the National Atlas layer "National Wilderness Preservation System" was used as the data source. In its present form source data varies from a scale of 1:10000 to 1:2,000,000.

Data Input

In its present state these data are intended for geographic display and analysis at the national level, and for large regional areas. This is a work in progress and dates on individual records represent the last known update date (see accompanying spreadsheet at http://www.wilderness.net/GIS/WildernessUpdates.xls and cross reference using WID for contact/source information where available). The intent is to replace smaller scale data with larger scale data as it becomes available. It is hoped that the end result will be a dataset at or near national map accuracy standards for 1:24000 (1:36000 for Alaska) scale data. In its present form source data varies from a scale of 1:10000 to 1:2,000,000 (see lineage for details on source scale).

Caution: The data displayed in WFDSS are intended for STRATEGIC USE ONLY. Always verify the positional accuracy of the data with local knowledge.


Boundary names containing "(Draft boundary)" have not been finalized and are not official. Different wildernesses treat inholdings differently, so you should consult agency-specific maps to identify the exact location of private inholdings within wilderness. Wilderness.net manages this map as a service to Internet users of digital geographic data. Wilderness.net is in no way condoning or endorsing the application of these data for any given purpose. It is the sole responsibility of the user to determine whether or not the data are suitable for the intended purpose. It is also the obligation of the user to apply those data in an appropriate and conscientious manner. Although Wilderness.net attempts to use the most current and complete geospatial data available, accuracy varies. Wilderness.net provides no warranty, nor accepts any liability occurring from any incorrect, incomplete, or misleading data, or from any incorrect, incomplete, or misleading use of these data.

Wilderness GIS Team Contacts

The WFDSS application is "data rich". It requires data which is spatially oriented and graphically displays information to support wildland fire and other natural resource decisions. Due to the type and number of interagency spatial data sets required in April 2009 an interagency GIS Team was formed to provide data support for WFDSS. This Team is responsible for acquiring, consolidating, and validating their agency spatial and tabular data. In addition this team developed and maintained communications among local, regional, and national agency personnel to improve the collection process and provide explicit guidance on data needs. The members of the WFDSS GIS Team are:
