My Cherry trees look like they are dying, the tops of the trees are losing their leaves and the trunks of the trees have little holes in them about i/8" in diameter like a beetle has emerged from it . My apple trees have the same hole in the trunk but the foliage seems healthy for now. The holes in the apple trees just appeared this year, the holes in the cherry trees have been there for 3 or 4 years. The cherry tree exhibits the same symptoms as the ash beetle infected ash trees.
