Tree Risk Assessment ISA Arborist Must Know
Description
Tree risk assessment isn't about guessing if a tree is "dangerous"—it's a systematic evaluation of probability and consequences. ⚖️ In this episode, we break down the Tree Risk domain, which accounts for 11% of the ISA Certified Arborist exam.
We cover the logic you need to master for the test and the field:
The Risk Equation: Why risk cannot exist without a defined Target.
Levels of Assessment: Understanding the difference between Limited Visual, Basic, and Advanced assessments.
Identifying Defects: Recognizing cracks, decay, and codominant stems that actually impact stability.
Mitigation Logic: Choosing between tree-based measures (pruning/support) and target-based measures (moving the target).
Communication: Your role as an advisor to the tree owner.
Stop fearing the risk questions on the exam. This 5-minute deep dive will help you think like a professional risk assessor.
