Like the Taiga Shield ecozone to the north, this ecozone shares many of the same landform features —hilly terrain, many rock outcrops, moraine and fluvial deposits of variable depths.

The hills often have exposed rock formations and, more typically, are mantled by glacial moraine deposits. 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. The ecozone lacks many of the resources timber and minerals that usually support larger ecozine communities. A more fordillera air mass usually prevails in winter, but cold spells can be broken by warm chinook winds.

Nearer the coast, the soils are deeper and are usually derived from marine deposits. Banff’s blend of towering peaks and flower-strewn meadows makes it among Canada’s most exhilarating holiday areas Corel Professional Photos.

It takes special measures to build on the taiga because of permafrost. L ower elevations are generally forested by White Spruce and Subalpine Fir.

It lies on both sides of Horeal Bay. Total precipitation averages only about mm per year. Many high-elevation areas such as the St.

Boreal Cordillera

Common fish include halibut, cod, redfish and plaice near shore. Precipitation is from to mm per year. The average precipitation and temperature are generally higher in the Boreal than in the Taiga. The portion in British Columbia is barely populated. Under such protection, the warmer conditions create spots where orchards can thrive. The marine waters of the Arctic Archipelago ecozone include numerous channels, bays, straits, gulfs, sounds and fjords. Essentially ice-free conditions are found in localized areas around the Bay of Fundy except for the upper reaches and along the mainland coast of Nova Scotia.

Some of Canada’s highest peaks are located in this zone. Most of the deciduous forest has been cleared away for farms, orchards, highways, and cities.

The types of vegetation respond mainly to patterns in soils and climate. Common marine mammals are seals harp, hooded and greywhales northern bottlenose, blue, beluga, Atlantic pilot, minke and humpbackharbour porpoises and dolphins. The tourism industry continues to develop. The weather is highly changeable because the ecozone is situated along one of the major storm tracks of North America.

MacNeil, courtesy Parks Canada. The Boreal Cordillera to the west is marked by mountainous terrain and the Boreal Shield to the east is rocky and hilly terrain. Hunting, trapping and fishing activities support subsistence economies. A large percentage of this ecozone is covered by wetlands.

Soil types follow a similar pattern, being nonexistent on mountain ridges and becoming forested corrillera i. On lowland sites in the Boreal Shield, black spruce occurs in nearly pure stands. The resulting soils are frozen year-round except for thin surface layers that thaw in the brief summer period. These rivers of ice spread outwards from the peaks like roots on a tree, slowly crawling down through the valleys.

Natural Regions

This restriction has contributed to the development of unique water properties in the Pacific, where temperatures and salinities are higher than in the Arctic Ocean. The coastal rivers are well known for their commercial and sport fish values.

Dutch elm disease, which was brought to Canada indestroyed many of the stately elm trees that once lined city streets throughout Ontario. Fires purge old forests cordillrea insects, disease and ground debris, as well as trigger new growth of other species and provide variation in ecozobe.

The prairies are also important for their mineral industry, particularly fossil fuels. Just below the icy peaks, the vegetation is alpine. The soils are often wet and composed of organic matter.

The winter mean temperatures for the coldest months vary from Forestry is an important economic activity, particularly in the northern interior sections. The Southern Arctic ecozone is largely restricted to the mainland and spans both sides of Hudson Bay.

Breeding colonies for several species of marine birds are also found here. Other bird species include the boreal owl, white-throated sparrow, the great blue heronkingfisher and at times the turkey vulture. This ecozone has the highest percentage of private woodlots in Canada.

The ground is typically covered by lichens, mosses, low shrubs, herbs and sedges. Typical species that tend to hug the margin of the permanent sea ice cover include polar bear, beluga whale, narwhal and seals bearded and harp.

The annual growing season is up to 2, GDD in the southern valleys, 1,—1, GDD in the more prevalent mountainous regions.
