Tree Risk Assessments

Tree risk assessment is the systematic process used to identify, analyze, and evaluate tree risk. Risk is assessed by categorizing or quantifying both the likelihood of occurrence and the severity of the consequences.

Tree risk evaluation is the process of comparing the assessed risk against given risk criteria to determine the significance of the risk. The magnitude of risk can be categorized or calculated and compared to the client's tolerances (or other predefined tolerances or ordinance requirements) to determine if the risk is acceptable.
