Taking Care of Tree Hazards
Makes Your Property Safer and
the Life of the Tree
15 , 2004
Consider these questions...
there large dead branches in the tree?
there detached branches hanging in the tree?
the tree have cavities or rotten wood along the trunk or
in major branches?
mushrooms present at the base of the tree?
there cracks or splits in the trunk or where branches are
any branches fallen from the tree?
adjacent trees fallen over or died?
the trunk developed a strong lean?
many of the major branches arise from one point on the trunk?
the roots been broken off, injured, or damaged by lowering
the soil level, installing pavement, repairing sidewalks,
or digging trenches?
the site recently been changed by construction, raising
the soil level or installing lawns?
the leaves prematurely developed an unusual color or size?
trees in adjacent wooded areas been removed?
the tree been topped or otherwise heavily pruned?
of defects present in urban trees...
from topping, line clearance or other pruning
line adjacent to tree
or partially attached branch
cavity in trunk or branch
or dying branches
arise at one point on the trunk
and rot present in old wounds
change in grade or soil levels, or other construction
of defects present in rural trees...
site construction, grading and tree removal; clearing of
forests for development
tree failures in the local area
leaning near target
trunk; branches and stems equal in size
areas with shallow soil
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:
the Target -- While we can't move a
home or a nearby power line, we can sometimes move picnic
tables, cars, landscape features, etc. to prevent them from
being hit by a falling tree.
Prune the Tree -- Remove the defective branches
of the tree. Since inappropriate pruning may also weaken a
tree, it is best done by an ISA trained professional.
Cable and Brace the Tree -- Provide physical
support for weak branches and stems to increase their strength
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.
