Important Information Concerning Extension Letters

Due to an increase in course cancellations as a result of COVID-19,  we have updated our process for extension letters.

If your certificate has expired since January 1st, 2021, and you are unable to attend a Wildlife Dangerous Tree (WLDT) course due to course cancellations, you will need to complete the online assessment for your course to qualify for an extension letter.

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.

Wildland Fire Safety
No extension option available

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.
