Program Overview

This course was developed in consultation with the Workers’ Compensation Board of British Columbia (WCB), British Columbia Hydro, Wildlife and Danger Tree Committee of British Columbia, and numerous reviewers around North America.The course is administered by the Pacific Northwest Chapter of the International Society of Arboriculture (PNW-ISA).

The need for the course was defined in British Columbia by a tree-caused fatality in 2000 which helped WCB focus attention on worker safety on golf courses and inurban areas. PNW-ISA approached WCB to explore ways to design and implement a training course for the assessment of trees in urban areas and in the urban/rural interface areas. These discussions resulted in a project, funded by WCB, PNW-ISA,and BC Hydro, to develop a completely new course and accreditation. The course design work was undertaken by Dr. Julian Dunster of Dunster & Associates Ltd.

The effort involved several years of extensive research, testing, and review of the materials. In the summer of 2004, WorkSafe BC recognized the course and credential as an accepted industry standard in British Columbia. After a successful 2005 course launch in British Columbia, the course is now being offered in thePacific Northwest.

Course Intent

The intent of the course is to:

• provide tree risk assessment training for urban and urban/rural interface areas using the most current theory, practice, and technical concepts employed in arboriculture,
• set the standard at a high level of competence to ensure those accredited are skilled, knowledgeable, and fully aware of their professional responsibilities,and
• promote safety and sound arboriculture as a part of the course.

Course Information

The two-day course trains participants in the process of tree risk assessment. The combination of classroom lectures and field work includes modules on biology, structural mechanics, risk theory and practice, reading tree conditions, assessing and assigning risk levels, and prescribing risk mitigation strategies.

Upon successful completion of the course, participants will be accredited as PNW-ISA Certified Tree Risk Assessors and meet current industry standards. This training course applies to all work activities in and around trees located in urban and urban/rural interface areas. These include municipal or regional parks, golf courses, and other public land, development and construction sites, utility corridors, highways, railways, and rapid transit rights of way, riparian corridors, bicycle and hiking trails, greenways, and all private lands where risk assessment is requested to fulfill municipal, regional, provincial, or insurance company requirements.

Prerequisites

Participants will receive the course manual approximately three (3) weeks in advance and are strongly encouraged to read and study in detail before attending the course. Candidates are expected to have the ability to identify tree species, native or exotic, and to understand and apply basic biology, mechanics, risk assessment, and risk management concepts.

Equipment

• Required: Hard hat, field notebook, appropriate outdoor clothing
• Suggested: Increment borer, clinometers, binoculars, diameter tape      

Course Examination

The closed book exam is 2.5 hours in length. A mark of 85% or better is required to pass. This standard applies to the full two-day course as well as the challenge exam. Upon successful completion of the exam, participants will be accredited as PNW-ISA Certified Tree Risk Assessors.

The Certified Tree Risk Assessor qualification is good for a four-year period from the quarterly date of successful exam completion. Certification renewal options include attending the entire course again or writing a challenge exam. Recertification fees apply to both options.

Seating is limited to 15 full course registrants. Seating limit does not apply to challenge or retake exams. We do reserve the right, however, to limit attendance at any course.

Course Schedule

This is a two-day course. Day One lectures cover all material in the course manual. On Day Two, a morning outdoor field session helps participants learn how theory integrates into practice. The morning is spent examining trees and practicing assessment skills and data recording.

The exam is held on the afternoon of Day Two for 2.5 hours. A mark of 85% or better is required to pass. Those who score less than 85% are eligible for a retake exam (fees apply).
