Protection:
* Tree wrap: Wrap the damaged area with a protective material like burlap or plastic mesh. This will prevent further chewing and help the tree bark to regenerate.
* Hardware cloth: Wrap the trunk with hardware cloth, ensuring it's secured tightly. This is a more permanent solution, but it's important to make sure the cloth doesn't constrict the tree's growth.
* Repellents: You can try using commercial repellents designed for squirrels. However, these are often not very effective, and you'll need to reapply them frequently.
Healing:
* Pruning: If the damage is extensive, you may need to prune the damaged branches to help the tree recover.
* Fertilizer: Apply a balanced fertilizer to help the tree grow strong and healthy.
Prevention:
* Provide alternative sources of food: Squirrels often chew on trees because they're looking for food. Provide them with bird feeders, nut feeders, or other food sources to deter them from your trees.
* Plant squirrel-resistant trees: Some tree species are less susceptible to squirrel damage. Consider planting oak, maple, or birch trees.
Important Note:
* Avoid using glue traps: These can be harmful to squirrels and other wildlife.
* Consult a professional: If the damage is severe, you should consult with an arborist or tree expert.
Remember, the best way to prevent squirrel damage is to create an environment that makes your trees less appealing to them.
