Lands with Wilderness Characteristics

The Bureau of Land Management (BLM) is required to maintain inventories of Lands with Wilderness Characteristics (LWC). An inventory of wilderness resources on BLM-administered public lands is an important part of our management. The wilderness characteristics inventory is required to be brought up to date whenever the BLM is undertaking a land use planning effort or revision of land use plans. The Lands with Wilderness Characteristics Inventory (LWCI) is being reviewed and updated as a component of the data used in the Desert Renewable Energy and Conservation Plan (DRECP) and Western Mojave (WEMO) Route Network and Plan Amendment.

The BLM conducts the inventory process using the criteria from Section 2(c) of the Wilderness Act to determine the presence of wilderness characteristics, such as:

  • Size: the roadless area has at least 5,000 acres of contiguous public lands (or is of sufficient size to make practicable the preservation and use in an unimpaired condition);
  • Naturalness: the area generally appears to have been affected primarily by the forces of nature, with any human imprints being substantially unnoticeable;
  • Outstanding opportunities: the area provides outstanding opportunities for solitude or a primitive and unconfined type of recreation;
  • Supplemental values: the area may also contain ecological, geological, or other features of scientific, educational, scenic or historical value.

You can learn more information on the Bureau of Land Management's policy and guidance for conducting wilderness characteristics inventories by accessing the BLM Manual 6310: Conducting Wilderness Characteristics Inventory on BLM Lands.

The map and navigation below will direct you to the Lands with Wilderness Characteristics Inventory Reports conducted by the Field Offices. These Inventory Reports are not yet compliant with Section 508 of the Rehabilitation Act of 1973. These documents will be made 508 compliant as soon as possible.
