Benefits of QTRA

QTRA is a probabilistic tree risk assessment system that:

  • is repeatable
  • moves away from predictive assessment (we do not need to state that a tree is either safe or unsafe or that it will not fail).
  • provides protection for both the tree inspector and manager
  • reduces the need for hazard remediation particularly in low use areas
  • conforms to standards accepted (in the UK) as best practice in the management of industrial and workplace risk and provides:
    • a clear structure within which to assess tree safety
    • a framework within which trees can be assessed at all levels of detail, from an overview of a municipality to the detailed appraisal of a single tree
    • a numerical basis for comparative risk assessment of trees
    • a numerical basis for the application of a thresholds of tolerable and acceptable risks
