BLM State Wilderness Study Documents

Bright green, rolling hills partially covered by cloud shadows.In 1976, Congress passed the Federal Land Policy and Management Act, directing the BLM to identify and review all the public lands under its administration which possess the wilderness characteristics described in the Wilderness Act. The BLM conducted three phases of wilderness review: inventory, study, and reporting.  The documents on this page are the results of that process. The inventory documents describe the characteristics of the lands reviewed, and indicate which lands became Wilderness Study Areas.  The reporting documents summarize the study of the multiple resource values of each WSA, and include the “suitable” or “non-suitable” recommendation the BLM based on the values identified during the study, reported to Congress.  These documents represent the information known at the time of their publication and may not reflect current conditions, which may have changed since publication.
