Good day today 25th June 2014 I completed the international Society of Arboricuture (ISA) Tree Risk assessment Qualifications course (TRAQ) This training helps me to keep up to date with the latest practices methodology and procedures. This approach is Qualitative risk assessment using ratings of likelihood and consequences of an event to determine a risk level and evaluate the level of risk against qualitative criteria. what is assessed is target what the tree or parts of the tree can impact, Occupation rate of target area, Tree defects and conditions of the crown, trunk roots and root collar their fall distance and then on mitigation options. Then decision these options with the tree manager/owner's and then deciding on a course of action.
