Hazard Tree Evaluation
Hazard trees are trees that have a very real potential to fail and injure or damage
a target (homes, utility lines, cars, people.) Trees in populated areas usually are in
a more stressful physical environment than those trees found in the forest. In an urban/suburban
environment there is a much greater chance of a tree will fail due to the stressful conditions.
Many of the hazards of significant trees can be alleviated through early detection and
assurance of a good environment for their health.
Jim's evaluation takes many factors into account:
- History: Construction activity damage, change of grade or drainage,
torn limbs or topped trunks can all lead to a weakened structure.
- Signs of decay: Dieback and decay in limbs trunk, roots or crown
is a sign of real danger.
- Recent Exposure: Trees situated at the edge of a newly cleared open
space are not accustomed to the elements of wind and sun.
- Root system: Failure of roots can be devestating. Healthy roots usually spread
uniformly and are expansive, providing support, water and nutrients. Some species of tree are
suseptable to fungal infections.
- Environmental Conditions: Trees in unstable environments, such
as wet soils or significant slopes, can fail. Competition with other trees and plants (like ivy
and vines) for water and nutrients will weaken the tree.
The key to reducing the risk a tree hazard is to identify and correct the problem.
Jim's knowledge and experience can provide you the answers you need to make a thoughtful,
If the problem is detected early enough, the tree may be pruned or treated to reduce
the hazard. However, in some instances the tree cannot be properly managed, and removal
of the tree is advised.
For trees in decline, or ones that must eventually be removed because of their ultimate
size, consider early planting of replacement plants (of appropriate species) to reduce the
environmental effects and visual loss.
