The greatest danger to a tree from a large unprotected wound is that:

• A. The wound may cause immediate death
• B. The wound may become infected
• C. The wound will heal quickly on its own
• D. The wound will result in immediate sprouting

Answer: (B)

A large unprotected wound is most dangerous because it invites infection that leads to wood decay. When bark and cambium are removed, pathogens—fungi and bacteria—can enter the exposed wood and colonize it. Over time this decay weakens structural tissues, which can compromise the tree’s stability and increase the risk of branch or trunk failure, especially under wind, rain, or heavy loads. Trees do have defenses like compartmentalization and callus formation, and some healing can occur, but the process is slow and imperfect. Immediate death from a single wound is unlikely, and while sprouts may appear, they don’t address the underlying decay risk. The key danger is that infection and decay can spread internally and reduce the tree’s strength long after the wound first occurs.
