The bark is beginning to shed in large pieces from our local ash trees. Nearly every mature ash tree is dead or dying from the damage of emerald ash borer. The larva live between the bark and the wood, carving tunnels as they feed. The tunnels girdle the tree, cutting of precious circulation. It’s hard to appreciate the utter destruction taking place beneath that bark. The galleries cover every square inch of the area exposed here. The tree has no chance.
