Research & Development

The Quantified Tree Risk Assessment system has been developed over many years during which there has been invaluable feedback and comment from Registered Users reviewing or applying the system.

To maintain a consistently applied methodology and optimise the value of QTRA, feedback from users informs adaptation and modification of the system and dissemination of information and updates to users.  We welcome your cemments and feedback.


Join our Public Discussion Forum to discuss tree safety management with tree professionals, land managers and tree owners, or attend one of our training courses to become a Registered User of the system.
