Which of the following indicate potential internal decay after a storm?

• A. Cracks or splits in the trunk
• B. Hollow sounds on percussion
• C. Loose or peeling bark
• D. All of the above

Answer: (D)

After a storm, internal decay can be hidden inside the tree, so you rely on external clues to flag risk. Cracks or splits in the trunk suggest that the wood inside has been weakened and may be decaying, compromising structural integrity. When you strike the wood and listen, a hollow or dull sound often means there are cavities inside where decay has eaten away wood. Loose or peeling bark can indicate underlying damage or disease beneath the surface, with decay processes pushing bark away or preventing proper bark attachment. Each of these signs points to potential internal decay, and seeing them all together makes the concern even stronger. So, all of these indicators can signal internal decay after a storm. If you notice them, have an arborist assess the tree for safety and possible removal or remediation.
