VISUAL TREE ASSESSMENT
Method of assessing the structural integrity of trees using external symptoms of mechanical stress (such as bulges, reactive growth, etc. and defects (cracks, cavities, conks, etc.). There are three levels of assessment. Quick walk or drive by is level 1. Level 2 is walk around whole tree and assess tree from tree base to tree crown assessing health and risk. If needed hammer / sound testing is done to hear if hollowness in tree is observed. A probe may also be used to check depth of cavities or hollows in the tree. Level 3 is all of the Level 2 plus the use of intrusive testing such as drills, resistograph drilling or other methods to test the internal integrity of the tree.
TREE RISK ASSESSMENT
A systematic process used to identify, analyze, and evaluate tree risk.
The inspection of a tree or tree part due to the tree or tree part caused damage or harm to people or property. Assessment forensics of the tree or part to aid in determining why that tree or tree part failed. Have worked expert witness cases due to injury or death caused by tree or tree parts, if the tree failed due to disease or storm events, or if chemicals were used to damage or kill the tree.
TREE PROTECTION PLAN
Development of a plan to save one to many trees from activity that is near the critical root zones of the tree(s). Write up of Guidelines to Tree Protection and Construction Sequences. Tree Inventory is part of the tree protection plan which details the species, size and health and risk potentials of the trees in development.
