The back tree in the center of the photo and the one on the right side have been taken over by ivy. It won't show for a while, but we went up there and cut away all the ivy in a broad band around the base of those trees. Eventually the vines will die, the leaves will fall off and the trees will survive longer. It's imposible to pull all the ivy out of a badly infested tree, all you can do is kill it and let the leaves fall off.
