CAL FIRE's fire scientists and wildfire mitigation experts developed the map using a science based and field-tested model that assigns a hazard score based on the factors that influence fire likelihood and fire behavior.

The map has shown increased fire hazard due to California's climate change, which is increasing wildfire severity. The map has been updated to reflect the zones in California that are susceptible to wildfire to provide transparency for planning and preparedness efforts.
