In our analyses, we have sought: (1) to confirm cotton rats as the culprit by examining the relationship between cotton rat density and recent girdling activity as well as where cotton rats were present in the past in relation to old girdling activity, (2) to learn whether certain size classes of pines were selected over others, presumably because of their differential nutritional value, and (3) to determine how pine density influences the extent of girdling damage and evaluate the possible ecological role of cotton rats in succession.
