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 homeowner 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 braches and perhaps a crown cleaning to resotre a pleasing shape.
- More severe damage - large broken branches, split crotches, 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?" A tree care professional should be consulted to answer this question.
"Most aborists will take the time and effort to save a tree only if the tree will still be healthy, atractive and of value to the property owner after repairs," explains Tchukki Anderson, BCMA and staff arborist for the Tree Care Industry 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 topped by storms can be prime candidates for removal," says Anderson.
Other factors to consider when determining if a tree is worth saving:
- Species - Is this type of tree prone to pests and other problems?
- Age - Is the tree mature or over-mature?
- Vigor - What health condition was the tree in before the damage?
- Value it adds to the property - Does the tree still have value, even if partially damaged?
- Sentimental value - Is the tree a living monument?
If 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 to the tree crew and requires special techniques, addiing to the cost.
