Risk Assessments

A tree risk assessment determines the level of risk that an individual tree poses. The level of risk is determined by a combined measure of the likelihood and

consequences of tree failure. 

All of our Arborists are trained and certified in using the Quantified Tree Risk Assessment (QTRA) system, which quantifies the risk of significant harm from tree failure in a way that enables tree managers to balance safety with tree values and operate to predetermined limits of tolerable or

acceptable risk.

This type of report is commonly associated with applying for the pruning or removal of trees that require a

permit to be removed.
