Tree risk assessment (TRA) is a systematic process used to identify, analyze, and assess the potential risks associated with trees. By evaluating the risk of trees before and after a storm, mitigation measures can be taken to reduce the risk and preserve trees that have an acceptable level of risk. This type of assessment is typically performed by a qualified arborist who has been trained in evaluating trees and holds the ISA rating for tree risk assessment. Tree risk assessments are usually conducted after a storm or disaster to ensure that damaged trees are removed or mitigated.
When assessing a tree, an arborist will take into account a variety of factors such as soil conditions, what structures are endangered if the tree falls, the general health of the tree, exposure to wind, etc. There are certain elements that can indicate to an arborist that a tree is at risk of falling. These include signs of decay, dead branches, weak branch unions, root damage, and leaning trunks. If you've had a weather incident and damaged trees, Essel's arborists can help by performing a high-tech tree risk assessment and labeling the trees for removal or other type of mitigation.
Certified arborists prefer not to cut down trees if they can be avoided and, if possible, will do everything possible to save a tree.
