The terms girdling and ring-barking tend to be used synonymously in arboriculture, but in the presentation accompanying this CEU quiz, Dr. Greg Moore argues that these are two distinctly different processes, both in the actions taken by arborists and in the effects these processes have on trees. This presentation discusses research surrounding girdling and ring-barking, including tree responses, consequences of damage, and restorative measures. In discussing the two types of cuts, Dr. Moore shares how trees can often survive various levels of damage from either type of cut.
