Damage to Trees by Squirrels
Squirrel damage is caused by:
- gnawing the bark of trees. If a complete ring of bark disappears, the tree will die. This is because the food and water are transported up and down the tree in the bark - in the phloem and xylem. If the bark is removed, the tree starves to death because the transport links are broken.
- damaging the growing tip of the tree. This causes loss of apical dominance, resulting in the tree becoming multi-stemmed, & loosing form.
- wounding the surface of the tree, which allows infections to enter, causing disease and decay
