QTRA is internationally recognised and is based on the central principle of risk management of probability, consequence and severity. The QTRA methodology provides:

  • an accurate, credible and effective risk assessment for any number of trees

  • provides clearly actionable outcomes that allow risk management actions to be prioritised and undertaken across a broad range of tree conditions and site variables.
