The Boreal Plains Ecozone, as defined by the Commission for Environmental Cooperation (CEC), is a terrestrial ecozone in the western Canadian provinces of Manitoba, Saskatchewan and Alberta. It also has minor extensions into northeastern British Columbia and south-central Northwest Territories. [1] [2] The region extends over 779,471 km2, of which 58,981 km2 is conserved (7.6 percent). [3]
Wood Buffalo National Park, the largest national park in Canada, and Whooping Crane Summer Range, the only nesting and breeding area for the critically endangered whooping crane, are both located in the northern portion of this ecozone. [4]
Industry in this ecozone once consisted primarily of forestry and agriculture, but in 1967 Great Canadian Oil Sands Limited began extracting bitumen from the Athabasca oil sands. Operations there have expanded significantly since 2003, and the oil sands are becoming an increasingly significant economic factor in the region.
Overlaying a bedrock of Cretaceous shale and Tertiary sediments are thick deposits of soil that form a flat terrain in the Interior Plains. [5] It borders the Montane Cordillera to the west, closely following the border between Alberta and British Columbia. To its south is the Prairies ecozone for its entire extent, while to the north are the Taiga Plains, with its northeastern periphery adjacent to the Taiga Shield. 20 sub-region are located within the ecoregion. [6]
Covering 650,000 square kilometres (250,000 sq mi), it is a region of subdued relief with few lakes. However, meltwater from glacial retreat between 11,000 and 8,000 years ago resulted in extensive deltas and dunes, forming Lake Winnipegosis at the eastern end of this zone. [7] It is a remnant of Lake Agassiz, a large glacial lake. [7] Most rivers originate in the Rocky Mountains, flowing eastward through the zone. [7]
Oil, Forestry, and agriculture are the largest industries. The region is nearly covered by timber, about 84% of the region, [8] The Athabasca oil sands area around 141,000 square kilometres (54,000 sq mi) of land. Agriculture takes place mainly in the Peace River Country in Alberta and British Columbia. This can employ up to 20% of the land area, though it is typically less than that. Large communities include, Fort St. John, Grande Prairie, Fort McMurray, Hayriver, La Ronge, and The Pas.
This ecozone can be further subdivided into three ecoprovinces: [9]
Lying east of the Rocky Mountains, the region experiences low precipitation, averaging 450 millimetres (18 in) annually, [7] with 300 millimetres (12 in) in the west and 650 millimetres (26 in) in the east. However, this is greater than the rate of evaporation by over 100 millimetres (3.9 in) in the south, and 300 millimetres (12 in) in the north and at the foothills of the Rockies. The excess moisture promotes the development of wetlands and peat bogs, which account for between 25–50% of the ecozone's area. [10]
Summers are moderately warm, with mean July temperatures of 13 to 15 °C (55 to 59 °F), whereas winters may be very cold, with mean January temperatures of −17.5 to −11 °C (0.5 to 12.2 °F). [10]
Each province continues to work on defining subregions within the larger national ecozone system. [11]
The Alberta Natural Subregion – Natural Regions (2006) found within this ecozone are: [12]
The Manitoba Ecoregions within this ecozone are: [13]
The Saskatchewan Ecoregions within this ecozone are: [14]
A number of protected areas have been established to protect representative and/or significant portions of this ecozone. These include:
The Boreal Shield Ecozone, as defined by the Commission for Environmental Cooperation (CEC), is the largest ecozone in Canada. Covering 1.8 million square kilometres it covers almost 20% of Canada's landmass, stretching from northern Saskatchewan to Newfoundland.
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. A rugged and mountainous ecozone spanning 473,000 square kilometres, it still contains "two of the few significant agricultural areas of the province", 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. The interior plains are encircled by a ring of mountains. The area has a mild climate throughout the year, with typically dry summers and wet winters.
The Boreal Cordillera Ecozone, as defined by the Commission for Environmental Cooperation (CEC), is a Canadian terrestrial ecozone occupying most of the northern third of British Columbia and southern half of Yukon. Within it is found Kluane National Park and Reserve, and a small portion of the southern range of Nahanni National Park Reserve. Most of the area's population is based in the city of Whitehorse, and it contains most of Yukon's population. The portion in British Columbia is barely populated.
The Fauna of Saskatchewan include several diverse land and aquatic animal species. From the multiplicity of invertebrates and vertebrates, two have been chosen as symbols of Saskatchewan. Cenozoic vertebrate fossils reveal the geological evolution of the interior plains and its prehistoric biogeography. Today, Saskatchewan's ecosystems range from the sub-arctic tundra of the Canadian Shield in north Saskatchewan to aspen parkland, the Mid-Continental Canadian forests in the centre of the province and grassland prairie. Fauna inhabit areas unique to their own specific and varied breeding, foraging and nesting requirements. With a large land and water area, and small population density, the ecoregions of Saskatchewan provide important habitat for many animals, both endangered and not. Naturalists observing wildlife have enumerated shrinking and growing wildlife populations. They advocate programs and methods to preserve or re-introduce endangered species and identify programs of control for outbreaks of wildlife populations. A broad diversity of wildlife habitats are preserved as parks and reserves protecting the feeding and breeding grounds of protected and indigenous fauna of Saskatchewan.

This level of generalization is well suited for national scale reporting. In the last 20 years, all Provinces and Territories have refined and automated their respective regional ecological framework. It is important, then, to provide a current national perspective which accurately reflects current regional efforts. ... Detailed ecological information remains with jurisdictions.
