The bark provides protection for vesicular system that gives the tree the ability to survive and thrive. Girdling, also called ring-barking, is the complete removal of the bark (consisting of cork cambium or "phellogen", phloem, cambium and sometimes going into the xylem) from around the entire circumference of either a branch or trunk of a woody plant. No matter how much of the tree bark has been damaged, you will need to repair the wound. This causes peeling bark on willows.

The cells in the roots are essentially starved of energy and can no longer function in order to bring water and nutrients into the xylem. However, cork trees have all of their bark harvested every few years. In bicollateral bundles, the xylem is sandwiched between two segments of phloem. Some energy is stored in the roots, which allows them to temporarily continue to transport water. Removing the bark around the trunk is referred to as "girdling." If your willow tree bark is falling off, it could be a sign of borer insects. When a tree is injured, the injury generally breaks the bark, reducing the tree's ability to absorb water and nutrients.
