The ecology and management of moist mixed-conifer forests in eastern Oregon and Washington: a synthesis of the relevant biophysical science and implications for future land management. Gen. Tech. Rep. PNW-GTR-897. Portland, OR: U.S. Department of Agriculture, Forest Service, Pacific Northwest Research Station. 254 p.


Land managers in the Pacific Northwest have reported a need for updated scientific information on the ecology and management of mixed-conifer forests east of the Cascade Range in Oregon and Washington. Of particular concern are the moist mixed-conifer forests, which have become drought-stressed and vulnerable to high-severity fire after decades of human disturbances and climate warming. This synthesis responds to this need. We present a compilation of existing research across multiple natural resource issues, including disturbance regimes, the legacy effects of past management actions, wildlife habitat, watershed health, restoration concepts from a landscape perspective, and social and policy concerns. We provide considerations for management, while also emphasizing the importance of local knowledge when applying this information at the local and regional level.


Keywords: Disturbance ecology, landscape restoration, land management, resilience, stewardship.

In Pendleton July 1-2, 2014,  a Moist Mixed-Conifer Synthesis Meeting and Field Trip was held to bring together scientists, technical specialists, forest collaboratives, and policy-makers to discuss management strategies for eastside moist-mixed conifer forests with the following focus:



  • Review the latest research findings on moist mixed-conifer forests from Pacific Northwest Research Station’s “Science Synthesis” (in press), and provide opportunities for meeting and field trip participants to ask questions.
  • Further communications between science and management regarding possible uses for the synthesis product.
  • Identify next steps to further integrate moist mixed-conifer findings into Blue Mountains Plan Revision and moist-forest restoration efforts at the local level.
