Tree Care


Hazard Trees
A hazard tree has defects that weaken the tree's integrity and has the potential to strike a target. A target is anything of value such as a person, car, or house.

Tree Evaluation
Inspect tree roots, trunk flare, main stem, branches, and branch unions on all sides yearly and after severe storms for defect. Use binoculars to inspect branches of large trees.

Some defects in Hazard Trees include:
• Dead branches
• Cracks
• Weak branch unions
• Decay
• Cankers
• Root problems
• Poor tree architecture

Corrective Measures
When a tree has the potential to strike a target, move the target, if possible. Contact a Certified Tree Expert (CTE) to evaluate and resolve the hazard. CTEs have the expertise and skills to properly evaluate and treat hazard trees. The CTE may advise you to prune the affected branches or, if the tree has severe defects, remove the tree.

Preventing Hazardous Trees
Trees require maintenance. Properly prune all trees to promote good structure. When planting a tree, remember to choose the right tree for the right place. During construction, take care not to injure the tree or its roots.
