Predicting Burn Severity Patterns in Yosemite National Park and the Douglas Complex Fires in Oregon

Mountainous topography creates fine-scale environmental mosaics that vary in precipitation, temperature, insolation, and slope position. This mosaic in turn influences fuel accumulation, moisture, and forest structure that in turn influence patterns of burn severity. We studied the effects of varying environmental conditions on burn severity across a largely wilderness area in Yosemite National Park from 1984 to 2013.We were also fortunate to have pre-fire lidar data for a portion of the 2013 Rim fire in Yosemite and for three fires collectively known as the Douglas Complex fires that burned in 2013 in a managed landscape in southwestern Oregon. This allowed us to assess the relative influence of the biophysical pattern and pre-fire forest structure on patterns of burn severity. We also have examined the patterns of forest structures and openings that result from fires in both Yosemite and the Douglas Complex.
