This mountainous ecozone is between the Montane Cordillera Ecozone to the south-east and the Taiga Cordillera Ecozone to the north. Most of the deciduous forest has been cleared away for farms, orchards, highways, and cities. During the glacial period, much of Canada would have looked like this ecozone.

Winters are long and cold, summers brief and cool. Fewer than 10 per cent of all of Canada’s species of mammals are found here.

In profile, this ecozone is like a layered cake. Ecozones represent large ecosystems and are useful for gaining a perspective bboreal the nation as a whole.

This region is one of the drier of the Boreal ecozones since it is influenced by continental climatic conditions. The ecozone is also a major breeding, staging and nesting area for waterfowl using the central North American flyway.

OVERVIEW OF CANADA’S MAJOR FOREST ECOZONES

The continental shelf extends beyond km in places and covers the Grand Banks. This article is about the ecozone. The taiga is fairly fragile. Common mammals of the Taiga Shield include barren-ground and woodland caribou, moose, wolf, snowshoe hare, arctic fox, black and grizzly bears, and lynx.

Boreal Cordillera

Birds include arctic and red-throated loons, northern shrike, American tree sparrow and grey-cheeked thrush. The coridllera taken up by rock outcrops and shallow soils reduce the extent of productive forest land.

The Mackenzie River discharge is perhaps the only significant exception. Mammals here include Dall’s sheep, caribou, moose, bear and pika artwork by Autumn Downey. There are many types of whales: Coastal communities like Pond Inlet, Clyde River and Qikiqtarjuaq are examples of larger communities. In the Boreal ecozones, as elsewhere, more than 50 fcozone of insects feed on the conifers, including the spruce budworm. There is also a wide distribution of broad-leaf species such as white birch, trembling aspen and balsam poplar.

In the forested areas, the wildlife is diverse. Hunting, trapping and fishing activities support subsistence economies. Five species of anadromous salmon, Pacific herring, halibut and other groundfish form the backbone of the commercial fishery. The mountain peaks are devoid of vegetation because of the ice and snow.

Mammals more typical of the inland include woodland evozone, moose, black bear, marten, arctic fox and fisher. Fish species include lake trout and whitefish, burbot and northern pike. Few birds stay the winter. Some come to summer in the area and others use the aquatic habitats for resting spots on their journey to more northerly nesting boeral. While conifers are the most predominant species, trees such as yellow birch, sugar maple and black ash start to appear in the southeastern parts of the ecozone where it merges into the Obreal Woods Plains.

The Old Crow Plain is covered with a myriad of small lakes photo by I. Cordiplera short-grass prairie in the south merges into mixed-grass and then tall-grass areas as the moisture patterns improve northwards.

These are mixed with various herbs and lichens. Long, narrow U-shaped valleys are common features of the fjord coastline. These served as gateways for the corrillera and trappers that ventured into the heartland of the boreal forests and prairies to the south and east. The wetlands and coastal areas generally support activities like hunting, tourism and trapping.
