Overgrowth of Injury

Overgrowth of injury is a natural response of the tree to injury or damage. When a tree is injured, it responds by producing new wood around the damaged area in an attempt to repair itself. This new wood growth can appear as a raised or swollen area on the trunk or branch of the tree and is known as overgrowth of injury.

In lumber, overgrowth of injury can manifest as a raised or irregular area on the surface of the wood. This feature can be caused by a variety of factors, including insect infestations, disease, or physical damage to the tree. Overgrowth of injury is more commonly found in hardwoods than in softwoods.
