One use of the term, according to the United States Department of Agriculture Forest Service, is as follows: "Girdling severs the bark, cambium, and sometimes the sapwood in a ring extending entirely around the trunk of the tree." These can reduce the flow of water, nutrients, and sugars at this point on the trunk. Hydraulic conductance and photosynthesis were measured in kiwifruit (Actinidia sp.) This effect became more significant for the current year's treatment, after repeated yearly treatments. Girdling is one reason why you see young saplings with protective plastic around the trunk.
