The Wildlife/Danger Tree Assessor's Course (WDTAC) is recognized in British Columbia by the provincial Ministry of Forests and Range, Ministry of Environment, and WorkSafe BC (Workers' Compensation Board), as the current "standard of care" for assessing dangerous trees and evaluating wildlife habitat value in forestry, non-urban park, and wildland fire situations. Three 2-day course modules exist for the WDTAC.
