We have recently added support for QTRA – Quantified Tree Risk Assessment Method as described at www.qtra.co.uk.

On the TreeSafety Customise Survey webpage, use the Survey Templates button to select the QTRA methodology.  This will setup the OTISS risk assessment fields with the appropriate names and scores for Target Range, Size and Possibility of Failure. During a survey, when you enter (or change) any of these fields, then the Risk of Harm field is automatically calculated and colour coded using the QTRA V5.1 rules.

The QTRA feature is only available to registered QTRA users. To activate these features, please enter the registration number from your QTRA certificate on your Account Settings page – we will check it at www.qtra.co.uk.
