ISA Certified Arborist Practice Exam 2025 – 400 Free Practice Questions to Pass the Exam

A tree risk assessment is a crucial process used in arboriculture to evaluate the likelihood of a tree failing and potentially causing harm to people or property. This assessment involves a systematic approach, considering factors such as the tree's structural integrity, health, species characteristics, and environmental conditions.

The primary goal of a tree risk assessment is to identify any hazards that a tree may present. For example, signs of decay, cracks, or significant leaning can all indicate an increased risk of failure. By understanding these risks, arborists can make informed decisions regarding management, maintenance, and necessary corrective actions like pruning or cabling, to enhance the tree's safety and longevity.

Other options provided do touch on relevant aspects of tree care and health. However, they do not focus on the core objective of a tree risk assessment, which is specifically concerned with evaluating the safety risk posed by a tree rather than its age, nutritional status, or aesthetic value.
