Millions of trees in the Sierras and Central Coast are continuing to die off at an alarming rate from a lethal combination of drought, a bark beetle epidemic and warmer temperatures. Heavily impacted trees include Ponderosa, Lodgepole, Sugar and other types of pine trees. Federal officials estimate 26 million trees have been killed in the Sierra Nevada from November of 2015 through June of 2016. This number is expected to increase considerably throughout the year.
