FRAZIER PARK, CA - MAY 7: Dead and dying trees are seen in a forest stressed by historic drought conditions in Los Padres National Forest on May 7, 2015 near Frazier Park, California. According to an aerial survey conducted by the U.S. Forest Service in April, about 12 million trees have died in California forestlands in the past year because of extreme drought. The dead trees add to the flammability of a drying landscape that is increasingly threatened by large, intense wildfires. In some areas where extremely hot wildfires have occurred, as in the 437-square mile Cedar fire that burned across San Diego County in 2003, most trees have died and chaparral brush is displacing the forests and animals that rely upon them. The findings of the study were compared to similar surveys taken in July 2014. (Photo by David McNew/Getty Images)
