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).
Biogeoclimatic ecosystem classification (BEC) [1] [2] is an ecological classification framework used in British Columbia to define, describe, and map ecosystem-based units at various scales, from broad, ecologically-based climatic regions down to local ecosystems or sites.
British Columbia is the most biodiverse province with 18 ecoregions across 4 biomes. By contrast, Prince Edward Island is the least biodiverse with just one ecoregion - the Gulf of St. Lawrence lowland forests - encompassing the entire province.
This zone experiences the warmest and wettest climate in Canada. [2] The lower Georgia Strait may receive as little as 600 mm of annual precipitation, but other areas in this zone receive as much as 3,000 mm. [3] Moderated by the influence of the Pacific Ocean, the zone experiences mild winters and cool summers. [5]
There are three distinct types of vegetation on this coast: the forests of the coastal plain dominated by western hemlock (Tsuga heterophylla), western red cedar (Thuja plicata) and amabilis fir (Abies amabilis); mountain forest of mountain hemlock (Tsuga mertensiana), amabilis fir and yellow cedar (Chamaecyparis nootkatensis); and alpine tundra with sedge meadows and lichen-covered rocks.

This new ecozone map includes 18 terrestrial, 12 marine and 1 freshwater ecozone, the latter two of which were derived from the marine bioregions outlined by Fisheries and Oceans Canada in 2009. [8] [6] This comprehensive framework is currently in use by Environment and Climate Change Canada to determine protected area coverage of Canada's ...
Coastal southern British Columbia has a mild, rainy oceanic climate, influenced by the North Pacific Current, which has its origins in the Kuroshio Current. Hucuktlis Lake on Vancouver Island receives an average of 6,903 mm (271.8 in) of rain annually, and some parts of the area are even classified as warm-summer Mediterranean , some of the ...
