Title I, Subtitle F of the Omnibus Public Lands Management Act of 2009 (Public Law 111-11, March 30, 2009) designated as Wilderness some 517,000 acres of BLM-managed lands in Owyhee County, Idaho, previously inventoried as Wilderness Study Areas.  It released another 199,000 acres from WSA status for multiple-use.  
Public Law 107-361 (Dec. 17, 2002; introduced as H.R.2818, Aug. 2, 2001) authorized conveyance of approximately 10.23 acres within the Sand Mountain WSA to the owner of the Sand Hills Resort.  Conveyed acreage is exempt from all requirements of the policy for Management of Wilderness Study Areas.
Presidential Proclamation 7373 (Nov. 15, 2000) enlarged Craters of the Moon National Monument and transferred portions of four WSAs to the National Park Service: the Great Rift (335,123 acres), Raven's Eye (45,578 acres), Little Deer (33,531 acres) and Bear Den Butte (9,700 acres).  WSA acres in the Craters of the Moon National Monument that remain under BLM jurisdication continue to be managed under Section 603(c) of FLPMA and are counted in the Idaho WSA total acreage.
Public Law 103-64 (Aug. 4, 1993) designated the Snake River Birds of Prey National Conservation Area and released the Birds of Prey WSA (26,713 acres). 
A small amount of designated Wilderness (802 acres) in the Frank Church River of No Return Wilderness lies in the BLM Cottonwood Field Office.
