Retention of living and dead trees, singly and in patches, is key to maintaining biodiversity. 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” (i.e., the best available and accepted standards and practices) for assessing dangerous trees and evaluating wildlife habitat value in forestry, non-urban park, and wildland fire situations.
