TREE HAZARDS – final part

The International Society of Arboriculture publishes in its tree care website the following guidelines on planning for a beautiful, valuable landscaping for all needs. At ABOVE AND BEYOND – TREE SERVICE we can help you planning your next tree project!  Contact us if you have any questions!

Defects in Urban Trees

The following are defects or signs of possible defects in urban trees (see figure):

  1. regrowth from topping, line clearance, or other pruning
  2. electrical line adjacent to tree
  3. broken or partially attached branch
  4. open cavity in trunk or branch
  5. dead or dying branches
  6. branches arising from a single point on the trunk
  7. decay and rot present in old wounds
  8. recent change in grade or soil level, or other construction

Defects in Rural Trees

The following are defects or signs of possible defects in rural trees (see figure):

  1. recent site construction, grading and tree removal, clearing of forests for development
  2. previous tree failures in the local area
  3. tree leaning near a target
  4. forked trunk; branches and stems equal in size
  5. wet areas with shallow soil

Managing Tree Hazards

An arborist can help you manage the trees on your property and can provide treatments that may help make your tree safer, reducing the risk associated with hazardous trees. An arborist familiar with hazard tree evaluation may suggest one or more of the following:

  • Remove the target. While a home or a nearby power line cannot be moved, it is possible to move picnic tables, cars, landscape features, or other possible targets to prevent them from being hit by a falling tree.
  • Prune the tree. Remove the defective branches of the tree. Because inappropriate pruning may weaken a tree, pruning work is best done by an ISA Certified Arborist.
  • Cable and brace the tree. Provide physical support for weak branches and stems to increase their strength and stability.
  • Provide routine care. Mature trees need routine care in the form of water, fertilizer (in some cases), mulch, and pruning as dictated by the season and their structure.
  • Remove the tree. Some hazardous trees are best removed. If possible, plant a new tree in an appropriate place as a replacement.

Recognizing and reducing tree hazards not only increases the safety of your property and that of your neighbors but also improve the tree’s health and may increase its longevity!

Ensuring Quality Care for Your Tree

Trees are assets to your home and community and deserve the best possible care. If you answered “yes” to any of the questions in the tree hazard checklist or see any of the defects contained in the illustrations, your tree should be examined by an ISA Certified Arborist.
