Protecting Trees With Fencing
Individual trees can be spared from beaver gnawing by placing wire cylinders around the base of their trunks. The purpose of this heavy wire cylinder is simply to keep the beaver from getting to the tree. The cylinders can be made from 3 to 4 foot tall galvanized garden fencing (2" x 4" mesh).

 

(Notes: The fencing should extend 2 feet above the highest snow level to prevent winter chewing. It generally does not need to be anchored to the ground. Cut the bottom to fit a sloping ground, or to protect prominent roots from chewing. Leaving a few inches of space between the tree and the wire allows for tree trunk growth. Replace as needed with a larger diameter cylinder to allow for trunk expansion).
Abrasive Tree Paint Protection
Ingredients:
Paint: Exterior Latex (choose a color to match the bark)
Mason Sand (30 mil or 70 mil)
Formula Mix 5 oz sand per quart of paint, or
Mix 20 oz sand per gallon of paint, or
Mix 140 gm sand per liter of paint.
(Notes: Make only in small batches at a time on the day you are going to apply it. Using too much sand will cause the mixture to roll off the tree. Apply paint to bottom three to four feet of tree trunk. For best results, do not paint every tree, leaving some for beaver food. This formula does not work for saplings, so protect them with wire fencing). Leave some trees for the beaver. They were here before we were!
