What does a tree risk assessor need to evaluate to determine the risk of tree failure?

To determine the risk of tree failure accurately, a tree risk assessor must evaluate multiple factors that encompass the overall health of the tree, its structural integrity, and the environmental conditions surrounding it. The health of the tree involves assessing diseases, pests, or any physiological issues that might compromise its vitality. Structural evaluation looks at the tree's trunk, branches, and root system to identify any defects, weaknesses, or instabilities, such as cracks or leaning trunks.

Additionally, environmental conditions play a critical role in risk assessment, as factors like soil quality, weather patterns, and nearby infrastructure can influence how the tree interacts with its surroundings and when it might fail. Therefore, a comprehensive assessment that takes into account all these factors is essential for making informed decisions regarding the management and safety of the tree.
