Tree mortality in California crosses all land ownerships; government, citizens and private industry are working together to mitigate hazards and create more resilient forests.

The total number of trees that have died due to drought and bark beetles is an historic 129 million on 8.9 million acres.

High numbers of hazard trees in our forests and around communities, campgrounds, along roads, trails and utility corridors pose a significant threat to communities if a wildfire breaks out in the affected areas.
