The Montane Cordillera Ecozone, as defined by the Commission for Environmental Cooperation (CEC), is an ecozone in south-central British Columbia and southwestern Alberta, Canada (an ecozone is equivalent to a Level I ecoregion in the United States). A rugged and mountainous ecozone spanning 473,000 square kilometres, it still contains "two of the few significant agricultural areas of the province", [1] the Creston Valley and the Okanagan Valley. Primarily a mountainous region, it consists of rugged ecosystems such as alpine tundra, dry sagebrush and dense conifer forests. [2] The interior plains are encircled by a ring of mountains. [3] The area has a mild climate throughout the year, with typically dry summers and wet winters. [4]

The corresponding name in the United States for this ecozone, where it is classed as a Level I ecoregion by the United States Environmental Protection Agency, which is identical though differently-named than the CEC system, is the Northwestern Forested Mountains ecoregion.

Geography

It contains the headwaters for the Fraser and Columbia rivers and many of their tributaries, notably the Thompson and Kootenay.

It is bordered to the west by the Pacific Maritime Ecozone, to the north by the Boreal Cordillera Ecozone, to the northeast by the Boreal Plains Ecozone, and to the southeast by the Prairies Ecozone.

Ecoprovinces

This ecozone can be further subdivided into four ecoprovinces: [5]

Geography of Alberta

Alberta is one of the thirteen provinces and territories of Canada. Located in Western Canada, the province has an area of 661,190 km2 (255,290 sq mi) and is bounded to the south by the United States state of Montana along 49° north for 298 km (185 mi); to the east at 110° west by the province of Saskatchewan for 1,223 km (760 mi); and at 60° north the Northwest Territories for 644 km (400 mi). The southern half of the province borders British Columbia along the Continental Divide of the Americas on the peaks of the Rocky Mountains, while the northern half borders British Columbia along the 120th meridian west. Along with Saskatchewan it is one of only two landlocked provinces or territories.

Kootenay National Park National park in British Columbia, Canada

Kootenay National Park is a national park of Canada located in southeastern British Columbia. The park consists of 1,406 km2 (543 sq mi) of the Canadian Rockies, including parts of the Kootenay and Park mountain ranges, the Kootenay River and the entirety of the Vermilion River. While the Vermilion River is completely contained within the park, the Kootenay River has its headwaters just outside the park boundary, flowing through the park into the Rocky Mountain Trench and eventually joining the Columbia River. The park ranges in elevation from 918 m (3,012 ft) at the southwestern park entrance to 3,424 m (11,234 ft) at Deltaform Mountain.

Geography of British Columbia Overview of the geography of British Columbia

British Columbia is the westernmost province of Canada, bordered by the Pacific Ocean. With an area of 944,735 km2 (364,764 sq mi) it is Canada's third-largest province. The province is almost four times the size of the United Kingdom and larger than every United States state except Alaska. It is bounded on the northwest by the U.S. state of Alaska, directly north by Yukon and the Northwest Territories, on the east by Alberta, and on the south by the U.S. states of Washington, Idaho, and Montana. Formerly part of the British Empire, the southern border of British Columbia was established by the 1846 Oregon Treaty. The province is dominated by mountain ranges, among them the Canadian Rockies but dominantly the Coast Mountains, Cassiar Mountains, and the Columbia Mountains. Most of the population is concentrated on the Pacific coast, notably in the area of Vancouver, located on the southwestern tip of the mainland, which is known as the Lower Mainland. It is the most mountainous province of Canada.

North American Cordillera North American portion of the American Cordillera mountain chain

The North American Cordillera, sometimes also called the Western Cordillera of North America, the Western Cordillera or the Pacific Cordillera, is the North American portion of the American Cordillera, the mountain chain system (cordillera) along the western coast of the Americas. The North American Cordillera covers an extensive area of mountain ranges, intermontane basins and plateaus in Western/Northwestern Canada, Western United States and Mexico, including much of the territory west of the Great Plains.

Creston Valley Wildlife Management Area

The Creston Valley Wildlife Management Area is a Canadian river delta wetland and Wildlife Management Area near Creston in south-central British Columbia, on the floodplain of the Kootenay River at the south end of Kootenay Lake. Predominantly marshland, it was classified as a wetland of international importance on February 21, 1994, and is also a globally significant Important Bird Area. It is one of the "few significant agricultural areas of the province", and is in the Montane Cordillera. It stretches north along Kootenay Lake for approximately 20 km, and south to the United States border. It is both the only breeding site of the Forster's tern and the only site with leopard frogs in the province, as well as one of the few Canadian habitats for the Coeur D'Alene salamander. Creston Valley provides staging and nesting areas for migratory birds on the Pacific Flyway.

Atlantic Maritime Ecozone

The Atlantic Maritime Ecozone, as defined by the Commission for Environmental Cooperation (CEC), is an ecozone which covers the Canadian provinces of Prince Edward Island, Nova Scotia, and New Brunswick, as well as the Gaspé Peninsula of Quebec. It is adjacent to the Atlantic Marine Ecozone to the east, and the Mixedwood Plains to the west. The roughly-corresponding Level I Ecoregion to this ecozone in the United States Environmental Protection Agency's classification, which is also part of the CEC system, is the Northern Forests ecoregion, though that classification includes the woodlands and swamps of northern Michigan and Minnesota, which are adjacent to the Boreal Shield ecozone.
