Q.The bark is falling off Manitoba Maple tree
The bark is falling off of 2 of the Manitoba Maple trees in my backyard. These trees are close to 50 years old and I am thinking they may be dying, but where the bark has fallen off there are small holes.

This actually looks like the handiwork of a type of tree borer. Fore more information on tree borers, visit the following link:
