You are correct HH, the ash bore drills a D shape hole.
The logger we talked to had the same idea, let's get the oak/hickory/walnut.......... that was until we explained we DID NOT need the money. We only want a value for trees that are going to die anyway.
Now to be totaly honest, there are "some" walnuts on banks of creeks we will have cut and removed. This is based on roots being washed out or root freeze from exposure. What WILL NOT happen is a "rape" of our woods, we don't need the money. What we are trying to do is clean up a disaster............ it came from China and we are sending the infected logs back to China.....
As an owner of this property, I don't have a mortatge, I own it........... I will sell the salvage wood with little regret. My heirs will see the results of this plague, I hope I planned well for the renovation......
