Boreal cordillera

This ecozone has some of Canada’s warmest and wettest weather. The cougar, which preys on these animals, is almost as adept at climbing.

Some of the drumlins along the upper Back River are nearly flat and others west of Chantrey Inlet are among the most dramatic in Canada. With agriculture being so extensive, many of the traditional habitats for animals have been lost, and species with them. Other mountainous forms like buttes cylindrical-like forms and mesas flat-topped mountains with steep sides are found here.

Mountainous topography dominates the landscape, with numerous fiords and glacial valleys, bordered by coastal plains along the Pacific margin. The abundance of other popular fish, like salmon and herring, have had marked shifts in numbers. Summers are short with prolonged periods of daylight. At a certain level trees no longer survive, although a wide variety of flowers is seen. In the eastern portion of the ecozone, balsam fir is often the dominant species, but the challenge is to protect it from spruce budworm a native pest that cordillrea be destructive during major outbreaks long enough for the trees to reach rotation age or a size at which they cotdillera be harvested.

Mammals of the Boreal Shield include moose, wolf, woodland caribou, white-tailed deer, black bear, porcupinebatraccoonmartenfisher, skunklynx, bobcat and eastern chipmunk. Some fish such as the Salish sucker are on the endangered list. Other species such as the cardinalCarolina wren and green heron are unique to this area.

The prairies are also important for their mineral industry, particularly fossil fuels. Near the poleward limits of trees to the south, the sizes of the shrubs vary from a metre and decrease to heights of a few centimetres toward the northern edge.

Because of the severe climate, vegetation is commonly ground-hugging and dwarf-like in form. Common mammals of the Taiga Shield include barren-ground and woodland caribou, moose, wolf, snowshoe hare, arctic fox, black and grizzly bears, and lynx. The main activities on the Taiga Plains are hunting and trapping. CalgarySaskatoonRegina and Winnipeg are among the larger urbanized areas.

Waters are relatively shallow, being less than m deep over broad areas. The Old Crow Plain is covered with a myriad of small lakes photo by I. The islands and mainland associated with this unit consist of mostly plains and rolling hills. Terrestrial ecozones of Canada.

The Boreal Cordillera ecozone, covering sections of northern British Columbia and the southern Yukon, has a Pacific Maritime influence that moderates temperatures over most of its area. Just over eight per centkm 2 of Canada’s land mass is contained in this ecozone. With a total population of 3 density 1. In the northern reaches of this ecozone, the average annual temperature is below The overall area receives up to 3, mm of precipitation per year.

The Prairie ecozone occupies an area from south-central Alberta to southeastern Manitoba.

Along the northern margins of this unit polar bear, walrus, ringed and harbour seals, along with beluga and bowhead whales can be seen. More precipitation falls in the Boreal Cordillera to the west.

Natural Regions

The tourism industry continues to develop. The waterfowl, in particular, rely on the Arctic wetlands and small lakes as key breeding and nesting grounds during the summer period. The types of vegetation respond mainly to patterns in soils and climate. The eastern areas are in a “rain shadow,” and receive only about mm per year.

I forgot my password. The soils are usually referred to as grassland or Chernozemic soils. Harvesting of both fish and marine mammals contributes significantly to the livelihood and culture of Aboriginal peoples. Mammals include muskox, wolf, arctic fox and bears artwork by Autumn Downey.

The Southern Arctic ecozone is where many of the more typical Arctic features begin to respond to the warmer temperatures and extended growing seasons. Hundreds of islands — as massive as Baffin Island and as small as Garnet Island — give this area a special character. The arctic sea ice rotates in a counter-clockwise, circumpolar gyre i. In the wetter lowlands, tamarack is more common.

Boreal Cordillera

Soils are generally frozen throughout most of the year and thaw to moderate depths in the summer. Geographic location, waterways, and a combination of gentle topography, fertile soils, a warm growing season, and abundant rainfall have made this the most densely populated and intensely used area in Canada.

The ecozone is a major habitat for waterfowl, especially the Canada goose. Soils are formed mainly in the few narrow valley bottoms. They often migrate great distances to the south to winter.
