Question
Visible on multiple tree species, cannot identify for sure but looks like spruce (but also species with flat needles). Observed on both the sunny and shady slopes of the mountain valleys. Old growth trees affected (whole trees observed with needles fallen off).
Answer
Thank you for your request. Unfortunately, determinig the exact cause of this damage is not easy. Your pictures shows a different species, and while each may contribute to the tree defoliation, it´s challenging to pointout the primary reason of this problem. If you are still interested in determining the reason of this problemme, I recommend taking some more pictures of the damaged areas, particulary defoliated branches, larvae or some other more visible symptoms. With best regards Milan Zubrik
