Old Tree Trunk Damage with Decay: Not Deer, Likely Past Wound Leading to Structural Hazard

Assessment

The damage is old, with significant internal decay under lost bark. Deer are unlikely the original cause; they may have rubbed on existing wounds. Decay fungi enter through bark injuries and progress slowly but irreversibly.

Implication

The extent of decay warrants tree removal and replacement, especially near structures/power lines. No treatment reverses advanced internal decay.

Prevention for Other Trees

• Protect trunks from mower/string trimmer damage.
• Prune properly to avoid stubs and tearing.
• Monitor for early signs of decay (conks, cracks, seepage).
