TREE CARE

Most trees and shrubs in cities or communities are planted to provide beauty or shade. While these are excellent

benefits, trees and shrubs serve many other purposes. They beautify our surroundings, purify our air, manufacture

precious oxygen, act as sound barriers, and help us save energy through their cooling shade in summer and their

wind reduction in winter. Providing care for trees on their property is a responsibility as a homeowner that is very

commonly overlooked.



The first thing to be sure of is that your trees are not a hazard. Below are tips provided by the International Society

of Arboriculture to help identify if your tree is hazardous or not.



Recognizing Tree Risk


Learn to identify common tree defects that may indicate tree risk and understand how tree risk can be managed.

 

Trees provide significant benefits to our homes and cities, but when trees fall and injure people or damage property,

they are liabilities. Understanding and addressing the risks associated with trees makes your property safer and

prolongs the life of the tree. Take care of your trees and they will provide you with continuous enjoyment.
 

Trees are an important part of our world. They offer a wide range of benefits to the environment and provide
tremendous beauty. However, trees may be dangerous. Trees or parts of trees may fall and cause injury to people

or damage to property. It is important to assess trees for risk. While every tree has the potential to fall, only a

small number actually hit something or someone — a target. There is no such thing as a completely “safe” tree. 

It is an owner’s responsibility to provide for the safety of trees on his or her property. Regular tree care will help

identify trees with unacceptable levels of risk. Once the risk is identified, steps may be taken to reduce the likelihood

of the tree falling and injuring someone.


Trees that fall into utility lines have additional serious consequences. Not only can they injure people or property

near the line, but hitting a line may cause power outages or surges, fires, and other damage. Downed lines still

conducting electricity are especially dangerous. A tree with a potential to fall into a utility line is a very serious

situation.
 

Tree Risk Checklist
 

Consider these questions:
 

  • Are there large, dead branches in the tree?

  • Are there detached branches hanging in the tree?

  • Does the tree have cavities or rotten wood along the trunk or in major branches?

  • Are mushrooms present at the base of the tree?

  • Are there cracks or splits in the trunk or where branches are attached?

  • Have any branches fallen from the tree?

  • Have adjacent trees fallen over or died?

  • Has the trunk developed a strong lean?

  • Do many of the major branches arise from one point on the trunk?

  • Have the roots been broken off, injured, or damaged by lowering the soil level, installing pavement, repairing 

sidewalks, or digging trenches?

  • Has the site recently been changed by construction, raising the soil level, or installing lawns?

  • Have the leaves prematurely developed an unusual color or size?

  • Have trees in adjacent wooded areas been removed?

  • Has the tree been topped or otherwise heavily pruned?
     

Defects in Urban Trees


The following are defects or signs of possible defects in urban trees:



  • Regrowth from topping, line clearance, or other pruning

  • Electrical line adjacent to tree

  • Broken or partially attached branches

  • Open cavity in trunk or branch

  • Dead or dying branches

  • Branches arising from a single point on the trunk

  • Decay and rot present in old wounds

  • Recent change in grade or soil level, or other construction


Defects in Rural Trees
 

The following are indicators or signs of possible defects in rural trees:
 

  • Recent site construction, grading and tree removal, clearing of forests for development

  • Previous tree failures in the local area

  • Tree leaning near a target

  •  Forked trunk; branches and stems equal in size

  • Wet areas with shallow soil
     

 

Managing Tree Risk
 

An arborist can help you manage the trees on your property and can provide treatments that may help reduce the risk associated with certain
trees.

An arborist familiar with tree risk assessment 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. Such supports are not guarantees against failure.

  • Provide routine care. Mature trees need routine care in the form of water, nutrients (in some cases), mulch, and pruning as dictated by the season and their structure.

  • Remove the tree. Some trees with unacceptable levels of risk are best removed. If possible, plant a new tree in an appropriate place as a replacement.



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