Important Information Concerning Extension Letters

If your Certificate is about to expire, and you cannot attend an appropriate module due to Geographic Hardship (there are no courses available in your local area by the date of certificate expiry) you may be eligible for a one-time (per module), 90-day certificate extension.

For Forest Harvesting & Silviculture and Parks & Recreation, you will need to complete an online assessment for your course, and successfully pass, to qualify for an extension letter. Should you not pass, there is a $50 fee for each additional attempt at successfully completing the online assessment.

This assessment will evaluate your current WLDT knowledge, and ensure you have the relevant information needed to complete your job.  Once you successfully complete the assessment with a minimum grade of 80%, an extension letter will be created and emailed to you. To access your course assessment please use the respective links below, where you will be prompted to create an account. If you need assistance, please contact our main office at cstudies@unbc.ca.

For Wildland Fire extensions there is no online assessment requirement.  Please email your request for an extension to cstudies@unbc.ca.

For those whose Wildland Fire Safety Certifications expired as of July 1st, 2021, you can apply for a one-time 90-day extension. The caveat around not having had an extension previously has been waived in order to ensure people’s Certifications remain valid through the 2021 Fire season.  After receiving this one-time extension, people will be required to take a Fire course to renew their Certifications.  To make your extension request please email Lesley Haines at Lesley.haines@unbc.ca.

The Wildlife Dangerous Tree Assessor Certificate consists of three modules that provide specialized training in proper assessment and procedures for resolving wildlife dangerous trees in specific forestry and industry-related operations.

1. Forest Harvesting & Silviculture Module

The Forest Harvesting & Silviculture Module teaches students to identify wildlife trees and assess the necessary steps to ensure worker safety and habitat protection when operating around wildlife/dangerous trees. The knowledge and techniques learned in this course are applicable to workplace activities in forestry operations, silviculture, oil and gas, and road construction/deactivation.

2. Parks & Recreation Module

The Parks & Recreation Module is developed and designed specifically for parks and recreation sites, and municipal settings, such as urban parks, where exposure to potentially dangerous trees may occur.

3. Wildland Fire Safety Module

This course provides students the knowledge and technical procedures for assessing tree hazards and establishing appropriate safe-work practices in situations where there is potential exposure from dangerous trees to workers on the fire line. It also provides information on assessing both tree hazards and wildlife-tree habitat value, where opportunities exist.

Important Certificate Information

There are certain times of year that UNBC has limited capacity to deliver Wildlife Dangerous Tree Assessor courses, specifically during firefighting season.

For the month of June, custom Wildland Fire Safety module deliveries will be scheduled on a limited basis depending on instructor availability and fire safety considerations.  In July and August, Wildland Fire Safety module deliveries will cease, being offered again in September. 

During firefighting season (June/July/August), the Forest Harvesting & Silviculture and the Parks & Recreation modules will also be offered, but on a limited basis and dependent upon forest closures. 

Winter courses will not be publicly offered in the interior of BC from December 1 through March 1. We encourage you to register for courses early in the year, to ensure you are able to receive your certification prior to the start of the field season.

Courses may get cancelled under the following safety conditions: heavy rainfall or wind storms, restrictive overhead conditions (i.e. heavy snowfall), field sites not being accessible due to snow on the ground and/or road washouts.


Wildlife Dangerous Tree Assessor certificates are valid for a four-year period. To continue working as an assessor, you must renew your certificate no later than the expiry date printed on the card and letter. You will receive your pass/fail letter and/or wallet card in the mail two to three weeks from the date of grade submission to UNBC.

Outside of course delivery, field cards can be obtained from the following three sources:
1: Government of BC.
2: Parks and FHS hardcopies: call the Distribution Centre at 1-800-282-7955.
3: Fire hardcopies: call 250-387-5965 or visit your local Fire Centre to request a set.
