Tree Risk Assessment
Unhealthy and damaged trees can often pose a significant risk to people and property, which is why a tree risk assessment is so crucial to ensuring the safety of your employees, visitors, and guests. We perform industry-standard tree risk assessment. Following the American National Standard for Tree, Shrub, and Other Wood Plant Management – Standard Practices (Tree Risk Assessment a. Tree Failure), also known as ANSI A300 Part 9. We assess trees using the formula Probability x Consequences = Risk.
Limited Visual Assessment
This is used when the tree will be viewed from a defined, limited perspective. It consequently has limitations as to which risks it may detect. This view may include an aerial patrol, a drive-by windshield survey, a foot patrol, or photographs.
Basic Tree Risk Assessment
This level involves looking at the tree’s roots, trunk and crown to detect structural defects. It is a 360-degree, ground-based visual observation of the tree.
Advanced Tree Risk Assessment
This level is anything in excess of level 2. It may include tissue testing, drone inspection and resistance drilling.
After potential targets are identified, our consulting arborists will provide a range of options to mitigate damage risks. There are essentially three options – removing the target, treating the tree, and treating the target. Removal is always a last resort if no other options are available.
