Poster Abstract: The biogeoclimatic ecosystem classification (BEC) system is a widely used management tool in British Columbia that describes climatic zones and site types using climax/mature plant communities as indicators of environmental quality. The classification has been widely applied for myriad applications requiring an understanding of biological communities and site potential. Even though the alpine tundra and adjacent high subalpine occupies over 150,000 km2, making it the largest climatic zone in British Columbia, it has received limited attention to date. I will present a preliminary provincial classification of high elevation subzones and some representative ecosystems.
