Management Direction for Large Diameter Trees in Eastern OR & Southeastern WA

Large and small trees growing close together in a dry forest area.

The USDA Forest Service Pacific Northwest Region released a proposal to amend land management plans on six national forests in eastern Oregon and southeastern Washington. The proposed amendment replaces the 21-inch standard with a guideline that emphasizes recruitment of a combination of old trees and large trees. 

The Eastside Screens were created in 1994 as an interim measure to protect riparian areas, encourage a healthy mix of young and old trees, and maintain wildlife habitat and connectivity. Now, more than two decades later, the “21-inch standard” has been reassessed considering current forest conditions, the latest science, project-level amendments, and public feedback.

Analysis of the proposed action resulted in a finding of no significant impact on quality of the human environment. The final decision notice and finding of no significant impact for the Forest Management Direction for Large Diameter Trees in Eastern Oregon project was signed by James Hubbard, Under Secretary for Natural Resources and Environment, United States Department of Agriculture, and became effective January 15, 2021.
