Abstract

The 2012–2016 drought and associated bark beetle outbreaks in California resulted in extensive tree mortality and provided a unique opportunity to examine questions of why some trees die while others survive these co-occurring disturbances and to increase understanding of how subsequent bark beetle-caused tree mortality alters fuel profiles and forest flammability over time. Our study objectives were to: (1) identify factors relating to conifer tree mortality and monitor changes in vegetation after mortality and (2) determine temporal changes in fuel loading and hazard due to bark beetle- and drought-associated tree mortality.
