Fourteen ecoregions comprise the Ecozone, ranging from the Mount Logan Ecoregion in the north to the Cascade Ecoregion and Lower Mainland Ecoregion in the south. The name of the comparable ecozones in the United States , where Level II ecoregions correspond to the international term "ecozone", are the Marine West Coast Forest and the ...
