California’s Estimated 29 Million Dead Trees Fueling Increased Wildfire Risks

The Forest Service survey of California shows that the number of dead trees in the state rose from 3.3 million in 2014 to an estimated 29.1 million in 2015. The 2015 surveys covered almost all of the state. Scientists and fire officials are concerned because under normal circumstances forests lose between 1 percent and 1.5 percent of their trees annually, but the state is losing between 7 and 20 percent of its forests.
