WHAT’S GOING ON IN THE FOREST?
I’m not sure you can tell or not from the photo, but one ash tree is looking healthier than the other. The ash on the right was treated 2 years ago, while the one on the left was untreated. This area in Sullivan County–for some reason–has experienced lower emerald ash borer pressure than others and is just beginning to show symptoms. The one on the right seems to be less chlorotic or darker green and it’s crown is fuller. I would have never noticed this if they were not adjacent to one another. Over time, I expect the untreated tree will begin to lose branches, experience bark damage and die off as others do.
