I'm dreading that dammed bug's arrival here. We have mainly an Oak/Hickory forest, but there are quite a few White Ash as well. I'm going to start taking out a few that are crooked, blocking sun from trees that have a future, etc. Like you said, Dennis, it just won't be the same out there, and I hate losing such a useful tree.
Maples are plentiful here as are cherry and locust. Already the holes left by the ash are filling with baby trees. Something is bound to fill the void and maybe forests go through a sort of evolution over time. It will be interesting ( for future generations) to see what grows there.
They do but again this is not a native pest. If pine nettles take out a pine stand that's one thing but when an import keeps wiping out natives and there is no natural predator tto that pest that's a problem.
