The tree that died suddenly on my property had small holes through out the trunk. Looked like some sort of boring insect got it. It also had a blackish trunk and well as a swollen trunk where it split in spots. I doubt the gas leak had anything to do with it. I've also have noticed that a lot of tree's around me are thinning, have a green lichen or moss growing on them, small and large hole in the trunk and the trunks are turning black.

I couldn't even begin to think of who to call about this either. I tried Rutgers and they were no help. I would love to find a person who knows about trees in the Cinnaminson, NJ area.
