Lands with Wilderness Characteristics Inventories

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 that will be used in the RMPs for Western Oregon planning project.

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 Conducting WildernessCharacteristics Inventory manual.

Map Summary of LWCs

In 2013, the BLM completed its LWCI updates for western Oregon and you can view the information here:

Each link will connect you to the full inventory findings located in the district selected.

The inventory findings contain a map of the wilderness area.

The BLM is in the process of uploading detailed inventory reports for all areas that were examined in detail and were found to lack wilderness characteristics for a variety of reasons.

If you have questions about LWCI, please contact the Wilderness and National Landscape Conservation System at 503-808-6086 or contact your local district office.
