All WSAs in the Planning Area will continue to be managed under the IMP, until such time as Congress either designates all or portions of the WSAs as wilderness or releases the WSAs, or portions of the WSAs, from any further consideration for wilderness and the lands revert back to general land use management.

Wilderness interim management is subject to valid existing rights and the grandfather clause under all of the alternatives.

The WSA designation is beneficial to the protection of air and watersheds, soil and water quality, ecological stability, plant and animal gene pools, archeological and historical sites, habitats for wildlife, and livestock grazing.
