The California Department of Forests and Fire (CalFire) now estimates that there are more than 66 million dead trees in the Southern Sierras alone, with many additional dead trees throughout California. According to CalFire, the number of dead trees has increased from 3.3 million in 2014 to 29 million in 2015 and now more than 66 million in just six counties. The huge increase in tree mortality is due to a combination of drought, climate change and bark beetles. The Governor’s Emergency Proclamation on Tree Mortality calls for removal of dead and dying trees in High Hazard Zones and conversion to bioenergy and other beneficial uses.
