Workshop Descriptions

Advanced Tree Risk Assessment

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.

Basics of Tree Biomechanics

This workshop will cover the basics of tree biomechanics, and how these principles can be used to guide pruning goals, tree risk assessment, and tree healthcare.

How have trees adapted to survive wind storms? When is a decayed tree no longer safe? How can we prune trees to increase strength through structure? If you have ever found yourself asking any of these questions, then there is an answer to be found in tree biomechanics. Tree biomechanics is the study of tree biology using engineering principles to better understand how trees have adapted to withstand various forces imposed upon them.

This workshop will cover the basics of tree biomechanics and show how to use the current findings in the field to better understand tree stability and wood strength. The goal of this workshop is to increase your knowledge of tree structure, and show how to use research findings to shape your arboricultural practices. The instructor will share how studies in the field are helping us learn more about tree behavior and predicting tree failure.

The workshop will include lectures plus interactive examples to learn how trees work. Workshop participants will examine tree samples to see and feel firsthand how taper, mass damping, and sway influence tree behavior.

Effective Report Writing: Guidance for Arborists and Urban Foresters

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.

Fruit Tree Pruning

Arborists are often asked to prune fruit trees that have been long neglected or haphazardly pruned without a clear philosophy. This class will equip participants with knowledge specific to fruit trees: common trained forms and pruning approaches, species-specific habits and challenges, and tactics to improve production of quality fruit. We will discuss how to interpret and approach client expectations and needs while prioritizing biology-based care, and opportunities for educating and partnering with clients. The day will consist of an indoor lecture, outdoor tour/demonstration on a site with diverse trees, and light hands-on practice in groups.

In-Person Attendance: Electrical Hazard Awareness Training

Arborists need to be aware of potential electrical hazards in their work environment.  Tree care brings arborists in close contact with energized power lines and equipment that have the potential for serious injury and fatalities. This training is for tree care professionals who want to avoid deadly encounters and other negative consequences with electricity.  Keep your crew safe with electrical hazard awareness training.

ISA Tree Risk Assessment Qualification

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.

ISA Tree Risk Assessment Qualification Renewal

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 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.

Oregon Forest Pest Detector Training: Help Combat the Tree Killers

Become part of Oregon’s frontline in the defense against invasive forest insect pests. In this workshop you will learn how to recognize the signs and symptoms of emerald ash borer and Asian longhorned beetle, two of Oregon’s least wanted forest threats. You will learn about current early detection and rapid response efforts and how to report a suspected pest so that it is handled quickly. These are good skills to have in the arborist’s toolbox and also a boost to keeping Oregon’s forests healthy. Learn about the following:

Remote Attendance: Electrical Hazard Awareness Training

Arborists need to be aware of potential electrical hazards in their work environment.  Tree care brings arborists in close contact with energized power lines and equipment that have the potential for serious injury and fatalities. This training is for tree care professionals who want to avoid deadly encounters and other negative consequences with electricity.  Keep your crew safe with electrical hazard awareness training.

Rising Above the Noise: Increasing Your Personal and Professional Impact and Influence

As arborists and urban foresters, we face many challenges and opportunities to help people understand and connect with the important role trees play in our daily lives. Yet so many people still take trees for granted. This presentation will help attendees with the “non-tree” aspects of moving their arboriculture and urban forestry efforts to the next level through three key contexts:

  • Personal effectiveness
  • Organizational growth
  • Collaborative action

The key messages are that we need to continuously learn and hone our “soft-skills” and strategic thinking abilities, we need to grow our organizations and companies to be both efficient and nimble, and we need to work collaboratively with each other to increase our influence and ability to rise above the noise that clamors for people’s attention.

Tree Appraisal Techniques

Working within the context of the 10th Edition of the Guide for Plant Appraisal, this two day workshop gives an overview of the appraisal process and provides an opportunity to practice in the field. Participants will review common mistakes and refine their craft as appraising arborists. Participants will learn about some of the key changes from the 9th to the 10th edition and apply the techniques in the field and in case studies.

The first portion of the workshop is a lecture that discusses the primary components of the Trunk Formula Technique (TFT) and a short history of the changes made from the 9th Edition to the 10th Edition.  Participants then divide into groups and appraise several trees using TFT. The class will reconvene and discuss the results.

The second day begins with an explanation of the concept of anchoring and how to evaluate the reliability, accuracy, and precision of data points. It explores methods of appraising partial loss, diminution of market value, percentage contribution, and net present value. Next, participants have an opportunity to reconcile different possible methods as they are applied to a given assignment. Participants, through a series of case studies, practice using the different appraisal methods and defending their conclusions.

Trees and the Law (Canada)

The workshop starts by understanding terms and legal principles and how these drive professional practice and possible advice to clients. This will include:

  • Duty of care
  • Standard of care
  • Negligence
  • Liability
  • Damages and penalties

With the use of case studies and reviews of court decisions, we will see why the courts favour or disapprove of certain actions, and that will then help to inform us about why professional practice requires certain set actions and processes that help to keep companies and clients better organized.

Various forms of damage will be reviewed including trespass, and personal and property damage, and the implications of these for the plaintiff and the defendant. The use of evidence and reports will be discussed to show how these can make or break a case.

The course will be suitable for anyone in the industry including tree care companies, municipal, utility, certified and consulting arborists.
