Borer Damage on Silver Maple
Hello! I have a young Silver Maple that I believe to be infested with some kind of borer, but I haven't had much luck finding pictures on Google of trees with similar damage. The outer bark is stripped away around where the small holes are, and the holes seem to be smaller than most that I've seen online. I saw the first hole about six months ago, and just recently several more have appeared. Do you have any guesses as to what kind of borer might be causing the damage and if there's anything I can do to help the tree?
