The authors reconstructed the species composition and structure of Engelmann spruce forest stand populations over a 319-year period between stand-replacing fire to determine how changes in the stand structure of spruce over time affect the size and severity of spruce beetle outbreaks.
This paper examines the post-fire recovery, resistance and resilience, of understory vegetation after a mega fire along a gradient of fire severities.
The authors reconstructed the fire regime characteristics of a warm-dry mixed conifer forest to evaluate potential changes to the fire regime since Euro-American settlement and examine the extent of high- or mixed-severity fire in these ecosystems historically.
Using the Forest Vegetation Simulator (FVS), the authors examined the effects of projected climate scenarios on future forest trajectories of ponderosa pine ecosystems in the Rodeo-Chediski Fire, and they further examined the potential effects of management strategies, including prescribed fire, to mitigate climate effects and increase resilience.
The authors reconstructed the fire regime before and after fire exclusion around approximately 1880 to determine if recent large, high-severity fire is within the natural range of variability for Sky Island ecosystems in the Pinaleño Mountains of Arizona, U.S.
The authors assessed potential future trajectories of forest stand structure in treated and untreated sites within the Rodeo-Chediski fire in response to multiple scenarios of climate change using the Climate-Forest Vegetation Simulator (FVS).
The authors compared treated and untreated areas after the 2011 Wallow Fire to assess if fuel treatments reduced fire severity and increased ecological resiliency of mixed-conifer forests based on three metrics: high severity patch size, tree survivorship, and nonnative/native herbaceous understory cover post-fire.
The authors examined the effects of initial fire severity on subsequent fire severity and also how the pattern of burn severity patches is affected by initial burn conditions.
The authors examined fire-on-fire interactions in two wilderness areas to determine the extent to which a wildfire can influence the severity of a subsequent fire and, if so, how long does the effect last. They also looked at the influence of topography and vegetation on burn severity of reburned areas.
The authors examined ponderosa pine stands using historic General Land Office (GLO) land survey data to reconstruct forest structure and fire regimes of pre-widespread European settlement on the Coconino Plateau and Grand Canyon National Park.
