How does the age of a tree relate to risk assessment?

The relationship between the age of a tree and risk assessment is important because older trees often have a greater likelihood of developing defects and experiencing health decline. As trees age, factors such as natural wear and tear, environmental stressors, disease accumulation, and exposure to decay organisms can contribute to structural weaknesses.

These factors are critical in risk assessment because they help determine the potential hazards an older tree may present, particularly in urban settings where proximity to people or property increases the stakes. The assessment will consider aspects like structural defects, the tree's vitality, and its overall stability, which can be adversely affected by age.

In contrast to younger trees, which may be more vigorous and less likely to have accumulated defects, older trees require careful evaluation to understand their condition and any necessary management actions to mitigate risk. This understanding assists arborists and risk assessors in making informed decisions about tree management and public safety.
