The first thing to do after a damaging storm is to carefully examine each injured tree for the type and extent of damage. Pay particular attention to trees that present obvious hazards to people of property. Large, broken branches or split portions of the main trunk that are still partially attached and hanging over houses, sidewalks, driveways, garages, or other buildings should be considered first. For safety reason, always allow the utility company to handle broken limbs or tree damage around power lines.
After hazards are eliminated and debris on the ground have been cleaned up, assess individual trees to determine whether further treatment is required. The effect of storm damage on the survival, longevity, appearance, and function of each tree must be judged, remembering that safety and the protection of people and property should be the most important consideration.
Severe splitting of the main trunk or any type of injury that results in removal of more than one-third of the bark around the circumference of the main trunk usually places the tree in severe jeopardy and may make removal necessary. Larger trees that have had broken tops are also poor risks. Broken side branches or minor trunk or top injuries do not typically put the tree at risk. Also, carefully inspect the tree for hidden damage. Identify cracks in the trunk or in large limbs. To reduce safety hazards, it is important to find hidden damage before repair work begins.
Any type of minor wounding may reduce the useful life of a tree. Such wounding can provide an entrance point for decay fungi or insects. Damage to trees also may reduce or destroy their intended function or severely disfigure the tree or ruin the appearance. The decision to retain or remove the tree depends on the individual situation.
