Why is species identification critical during risk assessment?

Species identification is critical during risk assessment because different tree species exhibit varying levels of vulnerability to environmental stresses and have distinct maintenance requirements. Each species reacts differently to factors such as pests, diseases, weather conditions, and soil types. For example, some species may be more susceptible to wind throw during storms or may have root systems that are less stable in poor soil conditions. Understanding these species-specific traits enables the assessor to accurately evaluate the risks they pose and implement appropriate management practices tailored to the particular needs of each species.

This knowledge is essential not only for determining current conditions but also for predicting future growth patterns and risk levels. When species are correctly identified, it allows for recommendations that can mitigate risks—such as pruning, cabling, or even removal—based on empirical knowledge of that species' characteristics. Consequently, accurate species identification is a foundational element in effectively conducting a tree risk assessment, leading to enhanced safety and better management practices overall.
