Benefits of qtra

QTRA is a probabilistic tree risk assessment method 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
