Heightened tree mortality in Western Washington
The majority of trees that DNR’s Forest Health Program has examined show no indication of being killed by pathogens, insects, or other animals. Fortunately, even in the hardest-hit stands, the majority of trees received adequate water and are unaffected.
Landowners may see an increase in the number of red trees as the weather heats up, but if green trees have put out a flush of new, expanding bright needles on branch tips this spring, they are likely to survive.
