WSA_ARC: This data set represents Wilderness Study Area (WSA) boundaries as inventoried in the mid1980's and defined in the October 1991 "Wilderness Study Report". Wilderness Study Areas are essentially roadless areas under BLM jurisdiction. Wilderness Study Areas have special management restrictions and priorities. They are a one-time designation and new WSA or additions to WSA are rare. For a complete description of this data consult the Wilderness Study Areas Spatial Data Standard. http://www.blm.gov/or/datamanagement/index.php
