Prospectus (en anglais) :

Tree risk assessment is an area of urban forest management that has evolved rapidly in the past decade. We have moved from simple hazard tree assessment concepts into a more sophisticated understanding of risk in general. With the introduction of the ISA’s Best Management Practices document for Tree Risk Assessment, and the Tree Risk Assessment Qualification (TRAQ), several new approaches and guidelines have been introduced. Within the field of tree risk assessment there are many techniques and concepts to master; from basic principles through to sophisticated diagnostic techniques.

This course will focus on Level Three advanced tree risk assessment, but will also link this to Levels One and Two to show when Level Three may be required, and how to relate it to other work.

This course will be delivered by Dr. Julian Dunster, the designer of the original Certified Tree Risk Assessor credential (TRACE) and author of the new ISA Tree Risk Assessment manual for the TRAQ course. The course will be of interest to anyone practicing tree risk assessment, and especially arborists already holding the Tree Risk Assessment Qualification.


Dr. Julian Dunster has unique academic and professional qualifications. He is a Registered Consulting Arborist, a Registered Professional Forester, and a Registered Professional Planner, and in addition to two degrees in forestry, he holds a Doctorate in Regional Planning and Resource Development. Julian has over thirty years of hands on experience from assignments all over the world, and his innovative work has been recognised with many awards. Julian uses these qualifications and expertise to provide you with practical, science based information, combined with a pragmatic understanding of what will or will not work well.

Key Factors

Levels of Assessment

Review how each level feeds into the next one to provide increasing levels of detail.


The Implications of Advanced Assessment: An Overview

  • why do you need it?
  • asking the right questions
  • knowing what to look for
  • knowing what you are looking at
  • professional and legal implications


Knowing What to Look For

  • baselines: the biological and mechanically ‘perfect’ tree
  • variations around ‘perfection’ and what they might mean
  • Knowing what you are looking at
  • Body Language: how to read and interpret it
  • Theorising ideas about what any one variation might mean
  • How to test your theory and see if you are right


Testing Techniques

  • Invasive versus non-invasive issues
  • discussion


Documenting and Defending the Results

The importance of clearly documenting the thought processes that lead you to undertake a Level Three assessment. Showing where, why and how you tested, and what you concluded based on the results.


Class Session Discussing Real World Examples

Participants are encouraged to submit beforehand a brief outline of a case study about investigations or anomalies they have encountered (details will be provided with the registration information). Up to six of these will be selected for presentation and discussion in class. We will examine the basic issues and then decide what we would have done, and how we might have interpreted the issues to arrive at a conclusion.
