Welcome to Biogeoclimatic Ecosystem Classification (BEC) System in BC Educational Training Site

This site provides an educational perspective on the Biogeoclimatic Ecosystem Classification (BEC) System in BC. The BEC system was developed by Dr. V.J. Krajina of the University of BC and has been adopted and expanded by the BC Ministry of Forests as a framework for managing ecosystems. Since the 1970’s, regional ecologists have continued to refine and develop the classification system.
