Workshop Descriptions

Common Fungi Affecting PNW Trees and Implications for Tree Risk Assessment

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:

  1. Know what to look for, and
  2. 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.

Emergency Response and Aerial Rescue

This two-day workshop is designed to educate tree climbers on the most likely scenarios where they may have to respond to an emergency. Emphasis is on emergency preparedness, readiness and accident prevention. The importance of self-rescue strategies and understanding the ‘working alone’ definition reinforces the importance of emergency readiness.

Participants are educated in the truths about tree work accidents and fatalities, information based on arborist statistics and industry reviews provides the basis for the specific rescue techniques trained and practiced. Participants are educated in key terms and definitions relating to rope parts, knots, hitches and specialized equipment. Physics concepts such as reaction force and potential energy associated with various rope rescue systems and configurations complete this comprehensive workshop.

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.
