The Tree Risk Assessment Qualification (TRAQ) is owned and developed by the International Society of Arboriculture (ISA).

The program expands your fundamental knowledge of tree risk assessment by learning a standardised, systematic process for assessing tree risk. You will be able to provide information to decision makers and tree owners to foster informed decisions that promote the safety of people and property, and enhance tree benefits, health, and longevity. You will learn strategies to systematically identify and assess tree risk.

This internationally recognised qualification course comprises of a two-day education course followed by a ½ day assessment (2.5 days in total) that includes both a written and field component. The course prepares the participant to take the TRAQ assessment to become ISA Tree Risk Assessment Qualified . It is required you attend the course and successfully complete the assessment in order to receive the ISA Tree Risk Assessment Qualification.

Tree Biology and Mechanics:

Participants will learn how to assess wood structure, decay, tree mechanics, and evaluate their impact on likelihood of tree or tree part failure. Participants will also learn how to identify and assess defects and conditions that may affect likelihood of failure.

Tree Inspection and Assessment

Participants will learn about types of targets, assess the likelihood of a tree or tree part impacting target, and estimate the consequences of tree or tree part failure. Participants will also learn how to assess site factors that may influence likelihood of failure.

Data Analysis and Risk Categorisation

After learning the tree and target factors that must be assessed, participants will combine likelihood of failure, likelihood of impact, consequences of failure to derive risk rating. This rating helps the assessor communicate tree risk to clients and risk managers and allows comparison risk levels between trees.

Risk Reporting

Participants will learn skills for clearly communicating tree risk to clients, both in written and verbal reports. Participants will also learn about the key components that should be included in a report after completing a tree risk assessment.

The qualification consists of a two-day educational course followed by a half-day assessment that includes both a written and a field component. You must attend the course and successfully complete the assessment in order to receive this qualification.

When applying to participate in a TRAQ event, applicants must agree to the terms, conditions, and policies outlined in the Tree Risk Assessment Qualification Application Guide.

All course registrants will receive a copy of the Tree Risk Assessment Manual and a course workbook. These are provided in hard copy to all in-person registrants, and in soft copy for any online refresher course attendees.

Flindersia australis (Australian Teak) It has really cool looking fruit capsules, the kids and I love watching them open and have done some time lapse photography on them
