Tree Risk Assessment Qualification (TRAQ) Practice Exam

Site conditions that hinder root growth and place targets nearby raise both the chance of failure and the potential damage if one occurs. Compacted soil reduces pore space, limiting root expansion and anchorage; poor drainage creates waterlogged, oxygen-poor roots; shallow roots further weaken stability. When a tree sits close to structures or busy walkways, any failure can cause direct damage to property or injury to people, increasing the consequences. In contrast, deep, well-drained soil helps reduce risk, soil color isn’t a risk indicator, and rainfall isn’t the sole determinant of risk.
