Why is decay detection important in tree risk assessment?

Decay detection is vital in tree risk assessment because it helps identify areas within a tree that have undergone degradation, which can significantly impact its structural integrity and stability. When a tree experiences decay, typically due to fungi or other pathogens, it can weaken the internal structure, making it more prone to failure during wind events or other stresses.

By locating specific regions of decay, tree care professionals can evaluate the potential risks posed by a tree, determine if it needs intervention or removal, and implement appropriate management strategies to mitigate hazards. This proactive approach is crucial in maintaining safety in areas where trees are near population centers, structures, or transportation routes, ensuring that decisions are based on accurate assessments of a tree's health and stability.
