The BLM OR Wilderness and WSA Map Service represents the congressionally designated BLM Wilderness areas (with Inholdings) and Wilderness Study Areas (WSA) (which are essentially roadless areas under BLM jurisdiction that met specific Wilderness Act criteria) within Oregon and Washington. WSA boundaries were inventoried in the mid 1980's and are defined in the October 1991 "Wilderness Study Report". WSAs have special management restrictions and priorities. They are a one-time designation and new WSAs, or an addition to an existing WSA, is rare. For a complete description of the data, consult the Wilderness and the Wilderness Study Areas Spatial Data Standards at: https://www.blm.gov/about/data/oregon-data-management.

The BLM OR Wilderness and WSA Map Service is created from wilderness.gdb\wilderness\wld_poly and wilderness_study_area.gdb\wilderness_study_area\wsa_poly. This map service has scale dependencies. Labels for the BLM Wilderness Study Area and the Forest Service Wilderness Study Area layers display at a scale in beyond 1:500,001. Labels for the Designated Wilderness display at a scale in beyond 1:10,000,001.
