Long-term effects of fuel treatments, overstory structure, and wildfire on tree regeneration in dry forests of Central Washington
Year: 2020
The long-term effectiveness of dry-forest fuels treatments (restoration thinning and prescribed burning) depends, in part, on the pace at which trees regenerate and recruit into the overstory. Knowledge of the factors that shape post-treatment regeneration and growth is limited by the short timeframes and simple disturbance histories of past research. Here, we present results of a 15-year fuels-reduction experiment in central Washington, including responses to planned and unplanned disturbances.We explore the changing patterns of Douglas-fir regeneration in72 permanent plots (0.1 ha) varying…

Dry Forests of the Northeastern Cascades Fire and Fire Surrogate Project Site, Mission Creek, Okanogan-Wenatchee National Forest
Year: 2009
The Fire and Fire Surrogate (FFS) project is a large long-term metastudy established to assess the effectiveness and ecological impacts of burning and fire “surrogates” such as cuttings and mechanical fuel treatments that are used instead of fire, or in combination with fire, to restore dry forests. One of the 13 national FFS sites is the Northeastern Cascades site at Mission Creek on the Okanogan- Wenatchee National Forest. The study area includes 12 forested stands that encompass a representative range of dry forest conditions in the northeastern Cascade Range. We describe site histories…

Masticating Fuels: Effects on Prescribed Fire Behavior and Subsequent Vegetation Effects
Year: 2009
In fire management, there is an ongoing quest to find cost-effective, ecologically sound, and risk-reducing approaches to restoring dry conifer forests. So far little is known about the effectiveness of using mastication equipment in conjunction with prescribed burning to help meet management and restoration goals. Richy Harrod is the Deputy Fire Management Officer at the Okanogan-Wenatchee National Forest in Wenatchee, Washington. He and his colleagues began to address this knowledge gap and found that mastication may be a cost-effective and important tool for managers looking for additional…
