Beetles killing more trees in Washington, likely due to drought [View all]
Washington had fewer dead or dying trees last year, but beetles that feed on dry trees caused greater damage across the state, a concerning trend for environmental officials.
The states annual forest health survey from the Washington Department of Natural Resources and the U.S. Department of Agriculture Forest Service found that Washingtons forests are suffering from increased heat, drought and wildfires, making them more susceptible to deadly beetles that feed on its bark.
Glenn Kohler, a forest entomologist at DNR, said that its hard to tell for sure if the drought is causing the beetle populations to spread, but it is likely.
I think theyre just breeding up in drought-stressed trees and moving to other drought-stressed trees, Kohler said. As long as these drought effects remain, I anticipate well see more.
