Quantified Tree Risk Assessment Ltd

QTRA training instructs delegates in the application of the Quantified Tree Risk Assessment method and gives an insight into the wider principles of risk management putting your observations of tree stability into the context of risk. Further, we explore how decay colonises trees, demonstrate how trees with good vitality are mechanically self-optimising, look at the limitations of strength-loss formulae, and show you how to map decay and sound wood with the Thor 710 hammer.
