A biogeoclimatic zone is defined as "a geographic area having similar patterns of energy flow, vegetation and soils as a result of a broadly homogenous macroclimate." [1] [2] All zones are officially abbreviated in capital letters (AT for Alpine Tundra, BWBS for Boreal White and Black Spruce, and so on).

Canada is unique among countries in that it borders three marine realms: the Arctic, Temperate Northern Atlantic, and Temperate Northern Pacific.These realms can be further subdivided into three marine biomes and fifteen marine ecoregions based upon biological distinctiveness.
The Vaseux-Bighorn National Wildlife Area extends over the Bunchgrass and Ponderosa Pine Biogeoclimatic Zones of British Columbia. [4] Both biogeoclimatic zones fall in the Coast and Purcell mountains' rain shadow, creating a dry climate in the Vaseux-Bighorn NWA with hot summers and relatively short winters. [4]
The dense and diverse forests make this zone the second most productive forest zone in British Columbia and Canada. Sub-Boreal ( Hemiboreal ) Spruce and Pine-Spruce Zones: The central interior of the province, consisting of the rolling lake-studded terrain of the Cariboo — the Fraser and Nechako Plateaus — is characterised by severe, snowy ...
The Thormanby Islands are located within the Coastal Douglas-fir (CDF) biogeoclimatic zone, [5] the smallest and most at-risk of British Columbia's 16 biogeoclimatic zones. [6] The CDF contains more species at risk than any other biogeoclimatic zone in BC, including 24 globally imperiled species and 282 species that are provincially-listed ...
The Ecology of the North Cascades is heavily influenced by the high elevation and rain shadow effects of the mountain range. The North Cascades is a section of the Cascade Range from the South Fork of the Snoqualmie River in Washington, United States, to the confluence of the Thompson and Fraser Rivers in British Columbia, Canada, where the range is officially called the Cascade Mountains but ...
The Boreal Mountains and Plateaus Ecoregion is unique among other British Columbia ecoregions in that it contains several volcanoes of late Tertiary and Pleistocene age. Level Mountain and Mount Edziza are the most prominent volcanoes of this ecoregion which reach elevations of 2,134 m (7,001 ft) and 2,787 m (9,144 ft), respectively.
