What role does tree health play in determining risk?

Tree health plays a critical role in determining risk because it directly influences various factors associated with a tree's structural integrity and resilience. A healthy tree typically has strong, intact tissues that can better resist environmental stresses such as high winds, snow loads, and diseases. When a tree is healthy, it is less likely to develop issues such as decay, fractures, or other structural failures that could lead to hazardous conditions.

Conversely, a tree that is unhealthy may be more susceptible to pests, diseases, and environmental damage, significantly increasing the risk of failure. For instance, if decay sets in due to disease or poor health, it can compromise the tree's structural strength, making it more prone to falling or losing limbs. Thus, evaluating the health of the tree is essential for conducting a comprehensive risk assessment, as it informs the likelihood of potential hazards associated with that tree. This understanding is pivotal in making informed decisions regarding tree management and safety measures.
