Question
WHAT IS THIS?
What is this material oozing form this tree? Photo taken in Mendocino National Forest.
AnswerI can not tell the species of the tree BUT it looks like a conifer tree. Assuming this it looks like a bark type insect more then likely a bark beetle and the conifer when the beetle cut the resin cells under the bark will exude pitch from the wound. It is not a real health problem to the tree unless there are numerous wounds up and around the trunk.
