However, trees may be dangerous. Trees or parts of trees may fall and cause injury to people or damage to property. We call trees in such situations hazardous, to signify the risk involved with their presence. While every tree has the potential to fall, only a small number actually hit something or someone.
It is an owner's responsibility to provide for the safety of trees on his/her property. This brochure provides some tips for identifying the common defects associated with tree hazards. However, evaluating the seriousness of these defects is best done by a professional arborist.
Regular tree care will help identify hazardous trees and the risk they
present. Once the hazard is recognized, steps may be taken to reduce the
likelihood of the tree falling and injuring someone.
