This ash tree volunteered from an old burn pile.  I was hoping it would develop into a nice shade tree, but I’m afraid it is not to be.   This is the first real sign of infestation I’ve seen in our neighborhood. We have a few other ash trees in the yard, and I would hate to lose them.  Apparently there are some systemic insecticides available in the last few years, which I’m reading about at http://www.emeraldashborer.info  The threshold for surviving is 50% canopy loss, so I think we’ll burn this tree in our woodburner, but will think seriously about treating the others.

Between drought and the emerald ash borer, this ash tree has had a rough summer.

Emerald ash borer grubs leave this typical “D” shaped exit hole in the Spring.  Woodpeckers have also taken an interest.
