TY - JOUR T1 - Quantified Tree Risk Assessment Used in the Management of Amenity Trees JF - Arboriculture & Urban Forestry (AUF) SP - 57 LP - 65 DO - 10.48044/jauf.2005.007 VL - 31 IS - 2 AU - Michael J. Ellison Y1 - 2005/03/01 UR - http://auf.isa-arbor.com/content/31/2/57.abstract N2 - A system of tree risk assessment is proposed that expands concepts developed by others and enables a probability of significant harm to be applied to tree failure risk. By evaluating the components of a tree failure hazard and assigning to them estimates of probability, the proposed system enables the skilled tree inspector to calculate the product of those probabilities to produce a numerical estimate of risk. The use of quantification in the assessment of tree hazards enables property owners and managers to operate, as far as is reasonably practicable, to a predetermined limit of reasonable or acceptable risk.
