What is the process of making shallow cuts in the bark of a tree called?

The process of making shallow cuts in the bark of a tree is called girdling. Girdling involves removing a strip of bark around the entire circumference of the tree or making shallow cuts that can inhibit the flow of nutrients and water within the tree. This method is sometimes used in forestry and tree management to promote the growth of other nearby plants or to manage tree populations.

While scoring might seem similar, it typically refers to making shallow cuts not necessarily meant to affect the tree's health but rather to aid in harvesting sap or other materials. Pruning and trimming generally refer to the removal of branches or foliage for better air circulation, light penetration, or aesthetics, and do not involve cutting into the bark in a way that would disrupt the tree's vascular system.
