They killed all my ash trees 3 years ago up here. The wood still has value until it falls even if its dead. Logger told me he would buy the ash until it fell on the ground and then it was too late. Bad thing is if they are going to log the loggers dont want just the ash they want the other hardwood too.

Ash damage looks like "D" on its side. The round holes are wood peckers working the tree. The bore gets under the bark and eats a ring around the tree killing it.

Some of my ash are falling since this summer so Im using them as firewood. h.h.
