Check trees for damage after storms

Winter storms cause tremendous stress and severe damage to trees in the urban forest. Obviously, a snapped or downed tree should be removed. What about a tree that suffers minor damage? How can a home owner tell if a tree is safe?

Assessing the damage
Minor damage - with only the smallest branches of the tree being injured - usually results in little or no permanent injury to the tree. All that is required is cleanup of the broken twigs and branches and perhaps a thinning prune to restore a pleasing shape.

More severe damage - such as large broken branches, removal of bark, and splitting or splintering of the trunk - can be caused by strong winds and heavy ice storms. When a tree is severely damaged, the first question that must be answered is: "Is the condition of the tree such that keeping it is worthwhile?"

"Most arborists will take the time and effort to save a tree only if the tree will still be healthy, attractive, and of value to the property owner after repairs," explains Robert Rouse, staff arborist for the National Arborist Association. A tree care expert may recommend removal of a tree that has brittle wood and a branch structure that makes it vulnerable to additional damage from future storms. Trees that have been previously damaged by storms are prime candidates for removal.

Other factors to consider when determining if a tree is worth saving include species; age; growing location; value it adds to the property; and sentimental value. If it has been determined that a tree is not worth saving, remove it as soon as possible. If it is not removed and the tree dies, it could become a hazard tree. Removal of hazard trees is dangerous and requires special techniques, adding to the cost.

Treating the tree
Assuming the decision has been made to repair the tree, the next question is: "Am I capable of repairing the damage myself or should I seek professional help?" Major repair will undoubtedly require the use of a chain saw and climbing equipment. Unless one is experienced in the use of such equipment and comfortable working off the ground, it may be best to have the work performed by a competent professional.

Inspect trees for damage after a storm. If a tree possesses hazards, such as broken or hanging limbs, have a reputable tree care company give an assessment. This is important because the owner could be held liable if the branch or tree falls and damages property or causes personal injury.
