Quantified Tree Risk Assessment Practice Note - Version 5.3.8

The Quantified Tree Risk Assessment Practice Note is a technical summary of the QTRA method as it is currently practised and includes guidance on how risk assessments can inform the management of risks from falling trees. 

Version 5 of the QTRA method is a substantial revision of the method with different risk outputs and new advice on how the QTRA risk of harm can inform management decisions. All tree managers using Quantified Tree Risk Assessments to inform the management of risks from falling trees should be familiar with this document, which can be downloaded here and distributed freely.
