Boeal polynyas — open areas of up-welling waters — remain open throughout the winter. As the Arctic has nearly 60 per cent of Canada’s estimated oil resources and 50 per cent of the potential gas resources, various oil and gas activities have been active in the area. Sperm whales are found offshore. These rivers of ice spread outwards from the peaks like roots on a tree, slowly crawling down through the valleys.

Boreal cordillera

Ice caps have their own majesty and form. Precipitous declines in groundfish stocks, particularly codled to drastic cutbacks in the fishing and fish-processing industries.

Some come to summer in the area and others use the aquatic habitats for resting ecoaone on their journey to more northerly nesting grounds. In the sense of nutrients, these soils are of moderate quality. The resulting soils are frozen year-round except for thin surface layers that thaw in the brief summer period. The coastal fringe is noted for extensive areas of stunted balsam fir and spruce. The more rolling aspects of the terrain in this ecozone are cordillear with the deposits of moraines.

The Rockies to the west, which block moisture-bearing winds from the Pacific, contribute to the dryness of this climatic regime. In profile, this ecozone is like a layered cake. In the nearby marine environment, typical species include walrus in the eastseals bearded, harp and harbourbeluga whales and narwhal.

Fewer than 10 per cent of all of Canada’s species of mammals are found here. L ower elevations are generally forested by White Spruce and Subalpine Fir.

The best forest growth is associated with White Spruce on fine-textured moist soil near wetlands and water. Commercial fishing concentrates on rainbow smeltwhite perch and common carp. Tim Fitzharris and John Livingston, Canada: Elias Mountains have perpetual ice and snow cover.

Huntingfishing and trapping remain activities for local residents in this ecozone, most of whom are Inuit. The climate is marked by hot, humid summers and cool winters.

OVERVIEW OF CANADA’S MAJOR FOREST ECOZONES

Some materials originated from old lake-bottom cordilleta lacustrine and others were derived from former sea-bottom deposits. The prairies receive less moisture than the Boreal Plains ecozone to the north, and experience periodic droughts. Archived from the original on June 25, The boreal forest in this ecozone supports the pulp and paper industry. Concentrations of humpback, bluefin and minke whales are typical in this ecozone.

Typical shrubs include dwarf birchwillows, Labrador tea and heath. Ecozones and ecoregions of British Columbia Geography of Yukon. Cordiillera bears roam the coastal areas. The land consists largely cordllera rolling plains along with some hills.

The ecozone has a strongly continental climate characterized by long, cold winters and short, warm summers except in the coastal margins where it is moderated by maritime conditions.

Breeding colonies for several species of marine birds are also found here.

Boreal Cordillera

Some examples of breeding bird populations unique to the ecozone within Canada include fork-tailed storm-petrelsBrandt’s and pelagic cormorantspigeon guillemot, marbled and ancient murrelets, Cassin’s and rhinoceros auklets, and tufted and horned puffins. Several mines have been successful ventures. The spruce component, retained for diversity and regeneration, is harvested about 20 years later.

Closed stands of conifers, largely white and black spruce, balsam fir, and tamarack, are characteristic. Over three-quarters of this ecozone is on the western side of the bay in the northern parts of the Northwest Territories and Nunavut.

The main activities on the Taiga Plains are hunting and trapping. These are mixed with various herbs and lichens. Mining, gas and oil production, and tourism are also significant economic activities in the ecozone.

Fire suppression and harvesting practices throughout the ecozone have also resulted in a shift from conifers to hardwoods, particularly in the boreal mixedwoods and the red pine and white pine stands in the southern part of the ecozone.

Underlying the surface are largely horizontal layers of sedimentary rocks. Ecozonr much more limited in extent, the lower Gulf Islands near Victoria and Nanaimo have the rarer Garry oak and arbutus trees.
