Large wildfire incidence has increased in forests throughout the western U.S. following changes in vegetation structure and pattern, along with a changing climate. Given this increase there is great interest in whether fuels treatments and previous wildfire can alter fire severity patterns in large wildfires. The 255,000 acre 2013 Rim Fire created an opportunity to study fuels treatment effects across a large forested landscape in the Sierra Nevada. We assessed the relative influence of previous fuels treatments (including wildfire), fire weather, vegetation and water balance on Rim Fire severity. We did this at three different spatial scales to investigate whether the influences on fire severity changed across scales.
