Priority Landscape Category
20-Year Forest Health Strategic Plan: Eastern WA Priority Landscapes
Description

120,477 total acres, of which 89,217 are forested.  Moderate to low risk of uncharacteristically large fires in most locations. DNR trustlands and Yakama Nation land occupy 86% of this landscape. Private land with homes covers a small portion in several canyons in the eastern portion. DNR's landscape evaluation identified 19,000-29,000 acres are recommended to be treated to move the landscape into a more resilient condition. This includes shifting an estimated 13,000– 16,700 acres from dense to open forest, while maintaining 28-40% of the overall landscape in dense forest to provide for habitat, wood production, and carbon storage. Maintenance treatments in existing open forest are needed on an estimated 4,000-8,000 acres. 

As of October 31, 2023, since 2017 in this priority landscape:

  • Individuals and organizations have reported 3,948 acres of forest health treatments completed impacting 3,761 footprint acres.
  • No acres have experienced low or mixed severity in the priority landscape, while 12,494 acres of Forest Practice Applications have been approved for some kind of active management.

Projects can be associated with multiple Priority Landscapes, but the simple project location marker is mapped in a single location. Therefore, some Projects may appear outside the Priority Landscape boundary.
