Tree Risk Assessments

Wherever trees are present, people, property and activities are at potential risk of injury, damage, or disruption. It is impossible to maintain trees free of risk; some level of risk must be accepted to experience the benefits that trees provide. Trees are a significant aspect of life in our urban environment; they provide us many health benefits, environmental benefits and economical benefits. These benefits increase as the size and age of trees increase.

Tree risk assessment is often a technical process that requires considerable knowledge, experience, judgement and skill. Our Tree Risk Assessment Qualified (TRAQ) Arborists have been trained by the International Society of Arboriculture to systematically inspect and evaluate your tree and the potential risk associated to it.

Tree Risk Assessment Qualified (TRAQ) is a new designation for ISA Certified Arborists who have successfully passed a rigorous test of their knowledge and skill with regard to evaluation of the structural condition of trees. Through a specific, step-by-step, process the Arborist can evaluate all aspects of a tree.

Tree Risk Assessment can be used for two reasons;

  1. Proactively identify high-risk situations before accidents occur. The Assessor can then recommend action so that damage to property and people can be avoided.
  2. To assure the Tree Risk Manager or the Tree Owner that the mechanical integrity of the tree is acceptable within his or her threshold for acceptable risk. The Assessor can suggest mitigation work that would bring the risk level within the threshold for acceptable risk.
