Doug Fir health/woodpecker
Hi, We have two very large Doug fir trees in front of our house and recently noticed a woodpecker damaging the trunk near the base of the south facing tree. I have included pictures of the trees and the woodpecker damage, wondering if this is a sign of disease or just poor health in this tree. Last year we added mulch to the area and I worry it didn’t let the roots of this tree breathe, is this a possibility for the cause of the issue and if so what can we do to help the tree?
