So, I've contacted the SCE, The forest service, the WW fire Dept, and the USDA. I've had very little luck in getting any information about bark beetle. It seems as though it may not be as big a problem as it was in the last drought.
SCE will remove the one tree that is at risk of falling on the power lines. They said they have no interest or obligation in the other trees on the neighbors lot or in identifying a bark beetle infestation.
My main concern is identifying if it is indeed a bark beetle infestation, and if so, how to 1. Remove the trees next door that are completely dead and 2. Make sure my trees and neighboring trees don't get infected.
Do I need a private arborist? Any recommendations?
