Saving Trees from Horse Bark Chewing and Preventing Recurrence

Damage Assessment

4 ft of bark removed around trunk (16–22″ DBH). Survival depends on cambium integrity.

If Cambium Intact (Tree Leafing Out)

• Grafting wax on bark to seal against insects/disease.

Prevention for Remaining Trees

• Wire mesh (rabbit cage) around trunks—physical barrier horses can't chew through.

Key Takeaway

Tree survival hinges on cambium damage. Wire mesh is the only reliable long-term deterrent for habitual chewers.
