219.27—Special designations.

The Forest Service may recommend special designations to higher authorities or, to the extent permitted by law, adopt special designations through plan amendment or revision. Special designations are areas within the National Forest System that are identified for their unique or special characteristics and include the following:
(a) Congressionally designated areas. Congressionally designated areas may include, but are not limited to, wilderness, wild and scenic rivers, national trails, scenic areas, recreation areas, and monuments. These nationally significant areas must be managed as required by Congress and may have specific requirements for their management.
(b) Wilderness area reviews. Unless federal statute directs otherwise, all undeveloped areas that are of sufficient size as to make practicable their preservation and use in an unimpaired condition must be evaluated for recommended wilderness designation during the plan revision process. These areas may be evaluated at other times as determined by the responsible official.
(c) Administratively designated areas. Administratively designated areas may include, but are not limited to, critical watersheds, research natural areas, national monuments, geological areas, inventoried roadless areas, unroaded areas, motorized and non-motorized recreation areas, botanical areas, and scenic byways.
