Class Descriptions

Advanced Tree Identification

This course is designed as a supplement and compliment to the Basic Tree Identification course. Where the basic course just touched the surface, this advanced identification workshop will do a quick review of the basics, and then focus in on key concepts and topics that will expand upon your base knowledge.  Topics covered more in-depth include basic botany and biology with the goal of providing a more thorough understanding of what differentiates trees into genre, and ultimately species.

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 beenintroduced. 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.

Basic Tree Identification

This basic identification workshop will cover topics to help the practitioner identify common species in the Pacific Northwest, both native and non-native, focusing on what to look for when the leaves aren’t available.  We will review common terminology and concepts that will help arborists and other green industry workers narrow down trees not covered in the workshop into genera, and ultimately lay the foundations for identification of most trees down to the species.

As there are well more species that can grow in our region than can be covered in a single basic workshop, focus will be on larger concepts that will lay the ground work for future identification. We will cover the use of dichotomous keys and get familiar with descriptive terminology to help narrow down unknown species.

Common Fungi Affecting Pacific Northwest Trees and Implications for Tree Risk Assessment

Improve your tree disease field assessment skills in this all-day class at Sunnyside Forest and Rotary Field House located at the South Surrey Recreation Center complex. Morning lectures will cover visual assessment techniques for disease, using a combination of signs and symptoms of common diseases in native PNW trees.

In the afternoon, we will be outdoors examining diseases of Douglas-fir, western hemlock, western red cedar, bigleaf maple, and Pacific madrone. The types of wood decay, fungus fruiting bodies, as well as structural and risk implications will be discussed, and sonic tomography and resistance drilling will be demonstrated as examples of advanced risk assessment techniques.

Creating Wildlife Habitat Trees

This class will discuss and demonstrate how instead of removing trees to the ground, portions can be safely retained and used as habitat. Demonstration will include techniques like ‘Coronet Pruning’ and how you can create bird boxes by either using pre‐existing cavities or creating them with the use of a saw. You will learn how you can attract the type of animal you are creating habitat for by the size and location of the holes you create, such as making large angled upward cuts into the side of a standing log creates a great space for bats to roost.

Electrical Hazards 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 Course

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.

Pruning, Planting and Selecting for Street Tree Diversity

The role of an Arborist often involves knowing and using expertise in the areas of pruning, planting and tree selection.  This workshop will start with nursery practices, learning about new tree cultivars and choices for various environments, in particular street planting.  Structural pruning of young trees, and dealing with root issues will also be covered as part of this workshop to help ensure tree success.

Tree Protection During Construction

Trees are commonly damaged during construction and successful preservation requires special consideration. This workshop explores strategies for managing trees during construction.

Learn about:

  • The importance of the arborist’s role throughout project planning, design, and construction;
  • The value of preserving existing trees with development;
  • Identifying trees that are suitable for preservation;
  • The possible ways trees may be affected by construction;
  • Tree protection measures and monitoring;
  • The use of alternative construction techniques to provide for tree protection; and
  • Addressing tree damage, risk potential and remedial treatments.

Trees and the Law

The presentation will include statutory enactments affecting trees and developments in law including those involving adjoining landowners, logging, timber trespass, public utilities, governmental police powers, governmental liability, trees and roadways, the rights and responsibilities of landowners, duty of care, negligence, and damages.  The presentation will specifically include measures of damages for damage to or destruction of trees.
