So many brown Doug-fir trees this year, what is the cause and is there a cure?

A:

We think that most of the problems this year are drought related - trees are stressed and then other insects and disease can more easily attack the trees. I spoke with our Forest Health Specialist, Dave Shaw. He recommended that you look at the following article: Many Douglas-fir with dead tops and branches in the Willamette Valley this year. I wish we had better news.
