Since 2010, an estimated 129 million trees have died in California’s national forests due to conditions caused by climate change, unprecedented drought, bark beetle infestation and high tree densities. Most visible and immediately concerning are the high number of hazard trees in and around communities and campgrounds and along roads, trails and power lines. PSW has been working with Region 5 to address tree mortality by using existing science and identifying future research opportunities. Learn about this latest research on PSW’s updated web pages on tree mortality in California, with videos and information on drought, bark beetles, wildfire risks, wildlife management and restoration strategies.
