Which assessment type produces a numeric value based on probabilities and consequences?

The choice of a quantitative tree risk assessment is correct because this type of assessment uses mathematical models and statistical analysis to produce a numeric value that quantifies the risk associated with a tree. In a quantitative assessment, both the probabilities of specific failure scenarios and the consequences of those failures are calculated, allowing for a more precise evaluation of risk.

This approach typically involves various metrics and data-driven methodologies, making it possible to assign numerical values that reflect the level of risk. This capability is essential for making informed decisions regarding tree management, as it helps to prioritize actions based on risk levels.

In contrast, qualitative assessments focus on descriptive characteristics and expert judgment without generating numeric risk values. Risk management assessments might involve strategies for mitigating identified risks but do not inherently produce the numeric evaluations characteristic of quantitative assessments. Visual tree assessments involve examining a tree’s health and structural integrity primarily through observation, which does not yield a numeric risk assessment based on probabilities and consequences.
