Testimonials from QTRA Users and their clients


"QTRA is a game-changer. A tree's risk is now backed up by a repeatable, auditable and transparent methodology, expressed in terms that a client or passer-by can understand.

The results of a QTRA can both reinforce and confound an initial visual inspection - trees which may previously have been condemned are able to be retained with a greater level of confidence than possible before. The days of home-grown risk assessment matrices are over."

Tom Hurley, Arboriculturist, Exeter, UK
