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.
This course will be of use to anyone interested in tree diseases, and particularly anyone conducting risk assessment of trees with disease.
Arborists and foresters conducting tree risk assessments need to:
- Know what to look for, and
- Know what they are looking at.
Fungi affecting trees show considerable variability in form and their ability to cause decay. Part of that variability is driven by the species of tree and fungus, the age and vigor of the tree, the extent of the fungal attack and associated decay, and the ability of the tree to compartmentalize the invading pathogens. Understanding the CODIT process is integral to understanding where decay may be within the tree. Minimizing bark scaring from park or forest management activities reduces the creation of fungal infection courts that threaten long-term tree health.
Writing is a critical part of communication. If the reader cannot understand what you are telling them, how do you expect them to proceed? In this class we will review how to write effectively. We will work on the writing styles needed to develop or respond to a request for proposal, as well as site memos, field reports, letter and formal reports with each one tailored to their intended use. The report themes will focus on risk assessment, construction sites, and site memos in general.
Introduction to Tree Climbing is a 2-day hands-on workshop designed for tree care professionals who want to learn or refresh the basic fundamentals, practice and safety protocols of tree access and climbing for arboricultural work. This course will teach those new to climbing the basic skills to be safe, efficient and productive out in the field. If students have personal climbing equipment they are encouraged to bring their gear to learn how to properly inspect the life support components. Emphasis on ANSI Z133 safety standards compliance will be an ongoing theme throughout the 2 day workshop to drive home the importance of safety.
The ISA Tree Risk Assessment Qualification (TRAQ) program provides an opportunity for professionals in the arboriculture industry to expand their knowledge through education and training in the fundamentals of tree risk assessment. This qualification promotes the safety of people and property by providing a standardized and systematic process for assessing tree risk. The results of a tree risk assessment can provide tree owners and risk managers with the information to make informed decisions to enhance tree benefits, health, and longevity.

The results of a tree risk assessment can provide tree owners and risk managers with the information to make informed decisions to enhance tree benefits, health, and longevity. The Tree Risk Assessment Renewal workshop is a one-day refresher, with five hours of instruction, and three hours of take the exam. Current TRAQ holders can complete the abbreviated course as early as four years into their qualification.
What is structural support and how does it affect tree health and longevity? The Structural Support Systems Workshop will be a 2 day workshop that is lecture based and hands-on. This workshop will cover the ANSI A300 Part 3 Supplemental Support Systems standards that are applied to the installation and maintenance of tree support systems, including cabling, bracing and guying. Various cabling approaches with be discussed such as bracing for split trees, through rods, and outside the box support systems. Static versus dynamic cabling systems will be compared, looking at where, when and why to install each system. Looking at structure support of weakened unions, wind dampening, and supporting abnormal growth structure, we will take a comprehensive approach at the purpose of cabling a tree and which system would likely be most successful. Cabling system construction and installation practices will be discussed to focus on the approach to find the most effective system to fit the tree.
