The Pacific Maritime Ecozone is a Canadian terrestrial ecozone, spanning a strip approximately 200 kilometres wide along the British Columbian coast, then narrowing along the border with Alaska. It also includes all marine islands of British Columbia, and a small portion of the southwestern corner of the Yukon. 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 Northwestern Forested Mountains. ecoregions. In the floristic province system, the region is described as part of the Rocky Mountain Floristic Region. Also in use is a system of biogeoclimatic zones defined and used by the British Columbia government, which defines the same area as the Coastal Western Hemlock zone, though a small portion flanking the Strait of Georgia comprises the Coastal Douglas-fir zone. In the different ecoregion system established by the World Wildlife Fund, the region corresponds to the Pacific Temperate Rain Forests Ecoregion, sub-ecoregions of which are the Queen Charlotte Islands ecoregion, Vancouver Island ecoregion, British Columbia mainland coastal forests ecoregions ==Geography== This ecozone is the most diverse in Canada, and perhaps the world. Its northern inland extent is primarily alpine tundra, whereas the picturesque northern coast features numerous fjords and valleys, with massive glaciers common in the mountains. To the south, the small flatland of the Fraser Valley is located at the southern end of the Coast Mountains, noted for temperate rainforests. In its marine areas are notable undersea kelp forests. Lying on the Pacific Ring of Fire, it exhibits many hot springs. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Pacific Maritime Ecozone (CEC)」の詳細全文を読む スポンサード リンク
