A bill to prohibit the removal by the Secretary of the Interior of certain areas from wilderness study status.

Prohibits the removal of an area from wilderness study area status on the grounds that such area comprises less than 5,000 contiguous acres if such area is: (1) contiguous with land formally determined to have wilderness or potential wilderness values; (2) contiguous with an area of less than 5,000 acres administered by an agency authorized to study and preserve wilderness areas, and the combined total of the two areas is 5,000 acres or more; or (3) subject to strong public support for wilderness identification and is of a size practicable and suitable for wilderness management.

Prohibits the removal of an area designated as a wilderness study area before December 31, 1981, from wilderness study area status: (1) on the grounds that such area lacks the requisite wilderness characteristics if it may possess such characteristics when considered in association with contiguous lands administered by an agency other than the Bureau of Land Management; or (2) on the grounds that such area overlays nonfederally-owned mineral rights.

Prohibits the Secretary of the Interior from modifying or revoking the inventory of public lands subject to review and designation as wilderness under the Federal Land Policy and Management Act of 1976 without express congressional approval.
