Abstract:

This data publication includes data collected as part of a research-management collaboration study of the short-term effects and economic viability of using mastication equipment - with or without subsequent prescribed fire - to precommercially thin overly dense dry coniferous stands in the eastern Cascade Mountains and reduce wildfire hazards. This study was embedded within the Hungry-Hunter Ecosystem Restoration Project on the Methow Valley Ranger District of the Okanogan-Wenatchee National Forest in north-central Washington State, USA. Responses of interest to Forest Service managers and scientists for this study included overstory structure, canopy and ladder fuels, surface fuels, tree regeneration, and understory vegetation. Data presented here include measures of overstory structure, tree regeneration, and surface fuels. Measurements were taken before (2004) and after (2007) mastication treatments and, where applicable, again after prescribed burning treatments (2008).
