Keep Trees Safe During Construction
CHAMPAIGN, IL-Are you planning to build a
home or remodel? Is construction planned in your community? Are trees on or
near the site? If so, remember to consider the negative impact of construction
on trees, cautions the International Society of Arboriculture (ISA). Jim
Skiera, Executive Director of ISA states, "People often buy treed lots because
they value the mature tree look then, due to construction activity, unknowingly
destroy the trees and end up paying large tree removal costs to then live on a
treeless lot."
"Many construction procedures can be devastating to surrounding
trees if no measures have been taken to protect them," said Skiera. "Visible
injuries are most recognizable, but it is damage to the root systems that often
results in tree loss." Planning can minimize some of these more common tree
damage problems:
Damage caused during construction
-
Soil compaction caused by increased foot traffic and heavy machinery decreases
soil oxygen and water pores, inhibiting root penetration, resulting in tree
health decline.
-
Severed roots - If just one major root is severed, the tree can loose 5 to 20
percent of its root system
-
Site clearing - Trees may be exposed to additional sunlight and winds after
neighboring trees are removed, blow downs may occur
-
Physical injury to the trunk, limbs, and branches
Plan ahead
Consult an arborist during the planning stages of construction to
assess potential hazards. Careful planning will save the expense and hassle of
repairing or removing damaged trees.
-
Construct barriers by setting up construction fences. Allow at least one foot
of space from the trunk for each inch of trunk diameter. A twelve-inch tree
needs a twelve-foot diameter fenced off area around the base.
-
Limit access and appoint one route as the main entrance and exit to the
grounds.
-
Monitor construction and work as a team with builders and your arborist. Your
vigilance will help the workers stay aware of your concerns.
-
Post-construction maintenance - evaluate the condition of all remaining trees.
Talk to your arborist about necessary maintenance and monitoring needs.
Treatment and repair
There are treatments that can save some trees harmed by
construction, but action must be taken immediately. Trees may need watering,
mulching, bracing, pruning, or even removal. Each tree should be evaluated
individually to ensure that it receives the appropriate treatment, repair, and
follow up care. For planning or tree care assistance during construction,
contact an ISA Certified Arborist in your area.
