Trees are dying

Millions of trees in the Sierras and Central Coast forests are stressed from higher temperatures, competition for water resources during this historic drought, and multiplying bark beetles. They simply can't withstand this deadly combination of stressors and are rapidly turning orange and dying. Even with the increased rainfall this past year, stressed trees will continue to die because while green, they have been invaded by bark beetles and just don't know they're dying yet.

Our forests are changing

A dead tree, the bark has fallen off and the trunk has been bleached by the sun.

Many agents interact to influence the makeup and structure of our forests, including insects, pathogens, and fire. Wildlife depend on snags (standing dead trees; #standingdead) for their survival. If a dead tree does not have the potential to endanger people or property, it could be left standing for our animal friends.
