Which aspect is NOT typically included in tree risk assessments?

In tree risk assessments, the primary focus is on evaluating factors that contribute to potential hazards posed by trees, such as their structural integrity, health, and environmental interactions. While the aesthetic value of a tree can influence decisions regarding its management, it is not a critical factor in risk assessment.

Species identification is essential in risk assessments as different species may have varying vulnerabilities to pests, diseases, and structural issues. Quantitative safety evaluation involves analyzing measurable data related to tree health and stability, which is integral to assessing risk. Historical damage assessments provide context regarding past incidents and patterns that can help in evaluating future risks associated with a tree.

On the other hand, aesthetics, while important in landscaping and tree management, does not directly impact the tree's risk of failure or harm to persons or property. Therefore, this aspect is generally not included in formal tree risk assessments.
