Woodpecker Holes in Silver Maple: Decay Indicator

Large silver maple has woodpecker nest hole in old pruning wound; new hole excavated 1 ft below. Owner fears tree decline.

Holes Signal Internal Decay

Woodpeckers excavate in softened, fungus-decayed wood. The tree may be hollow. Holes don't harm the living cambium—but structural strength decreases.

Management

• Annual fertilization: 10-10-10 at 1 lb/inch trunk diameter (spring after frost).
• Monitor for large dead limbs, lean, or cavity expansion.
• If hollow but sound, tree can live decades.
• If lean threatens structures, consult arborist for risk assessment.

Enjoy the birds; manage the risk.
