On a sunny day in June, about 30 acres of land tucked along rolling hills just north of Capay were set on fire. Wearing a bright yellow, long sleeve shirt, long pants, leather gloves, hard hat and heavy-duty goggles, UC Davis Assistant Professor Emily Schlickman participated in her first prescribed burn, a planned and controlled fire that aims to help reduce wildfire risk.

Just over 9,900 wildfires burned about 4.3 million acres in 2020. That’s more than twice the previous record of acres burned in California. Yet it is about average compared to burn rates likely experienced before Euro-American settlement, according to a study from the University of California, Davis, that summarizes the 2020 fire season and examines its drivers.
