The fire season of 2020 was unprecedented in the Western US. In one summer, three different fires individually broke the record of Colorado's largest wildfire. Understading the recovery following these historic events can lend insight into the compounding effects of wildfire and climate change. Reorganization of the understory community after disturbance can indicate changes in conditions not yet reflected in tree communities. Understory dynamics also affect watershed characteristic, wildlife, and tree regerneration, so knowledge about the influence of wildfire on understory plant communities is crucial. The purpose of this study is to determine if a trend toward thermophilization is being shown in understory vegetation following 4 different wildfires in 2020 and to compare the relative importance of burn severity, forest type, and other environmental factors on community composition. Thermophilization is an process in which the relative abundance of warm-adapted taxa in an area increases due to a warming climate, especially in combination with disturbances. We found a trajectory of thermophilization in high elevation forests that burned at high severity. We also found that drivers of community composition varied by forest type. These findings help assess how wildfire is affecting plant communities in the 21st Century and highlight what future management concerns may be.
