Question:

How can I prevent deer from rubbing off the bark on small trees in the yard?

Answer:

In fall, bucks rub their antlers on trees to remove the dried velvet from their antlers and to mark their territory.  This rubbing removes the thin layer of bark on small trees and can seriously damage or destroy them.  Trunk damage typically occurs 1½ to 3½ feet above the ground. 

Damage caused by bucks rubbing their antlers on small trees can be prevented by driving three sturdy wooden stakes or fence posts around each tree in late summer.  Space the stakes or posts about 18 inches apart.
