I've got some crab apple trees at work that appear to have been girdled over the winter by some type of varmit about a foot off the ground, suspect this was done by rabbits judging by the rabbit turds around the base of the tree. They lasted a year but didn't bloom or leaf out the following year and died. Wascawy Wabbits!
