The Canadian Shield is made up of the oldest known rocks some of which date back to the formation of the planet. (Humo-Ferric Podzol 3) They are forested soils found primarily on sandy parent materials in areas underlain by igneous rocks, most prominently on the Canadian Shield, but are also found in other regions on sandy glacio-fluvial deposits. Vegetation & Soil. (Humo-Ferric Podzol 3) They are forested soils found primarily on sandy parent materials in areas underlain by igneous rocks, most prominently on the Canadian Shield, but are also found in other regions on sandy glacio-fluvial deposits. Soil and vegetation- Thunder bay is in the wet climate soils, soil region. More suitable for the thin, sandy soil, evergreens such as spruce, pine, and fir thrive throughout this region. It comprises of northern coasts and all islands of Canadian Archipelago, which is often referred to as . By Graeme Wynn. Since the soil layers are so thin plants with big root systems are unable to sustain and grow on the Canadian Shield. Farmers would . The Canadian Shield makes up most of Canada and also two smaller parts in the United States of America. The variety of Boreal and Taiga forests contain mainly Birch, Tamarack, Spruce, Aspen, Willow, Hemlock, and Pine trees. A: Organic mulch includes residue of plants or crops. Summer days are a range from 18.5 hours in the south and 15 hours in the north. It is full of rivers, lakes, and a dike swarm that is the largest dike swarm known to Earth. The areas around Hudson Bay and James Bay are lowlands covered with clay. However the area has many marshes and bogs. The variety of plants makes the Canadian Shield rich with vegetation. The majority of the vegetation on the Canadian Shield is part of the boreal forest ecosystem filled with spruce, pine, birch, aspen, ash, poplar and fir trees since they have short root systems (Britannica, 2016). As a result, most rivers in the region flow into those two bays. Plants can grow to five by four feet (150 x 120 cm). It also covers parts of Greenland. Some of the world's oldest known rocks (about 3.96 billion years old) are in the Canadian Shield, located near Great Slave Lake (In the Northwest Territories). Some of the oldest rock on earth is exposed here, great outcroppings of Precambrian granite scoured clean by the Ice Age glaciers that retreated 10,000 years ago. Home Page > Vegetation. Though, since the northern part is far away from the south, there are a lot of Coniferous trees there. But the uneven distribution of these resources has shaped and sharpened political tensions within the country. The soil in the Canadian Shield is not leached or calcified and has a layer of bedrock directly underneath it. Since the soil layers are so thin plants with big root systems are unable to sustain and grow on the Canadian Shield. The crust, also known as the North American Craton, extends from northern Mexico to Greenland and consists of hard rocks at least 1 billion years old. Boreal forests are also made up of mostly coniferous trees such as pines, cedars, spruce, and fir trees. This area is at the intersection of the Canadian Shield metamorphic bedrock to the north and the Phanerozoic limestone bedrock to the south and is dominated by thin morainal deposits over bedrock. Because of there long roots, they can reach more nutrients. Taking into consideration that natural vegetation is generally influenced by climate (bodies of water, latitude, ocean currents, wind, elevation and landforms) and soil, this means that natural vegetation depends on all of the above mentioned . Ecologists recognize broad regions called ecosystems that are characterized by fairly stable complexes of climate, soils, and plant and animal life. Tundra. Many forests exist in the Canadian Shield. The rest of the region has coarse soil that does not retain moisture well and is frozen with permafrost throughout the year. The Canadian Shield, also called the Laurentian Plateau, or Bouclier canadien (French), . ecoregions within the Taiga , compared with Shield four described by the Ecological Stratification Working Group in 1995. The centre of the Shield is much lower in elevation than its' other portions. The Canadian Shields vegetation is primarily trees like birch trees, spruce trees, aspen trees, hemlock trees, willow trees. There are three important vegetation belts: the Tundra, the Taiga and the Prairies. There isn't much good farm land, because of the thin soil, with an exception of northeast Ontario and areas in Quebec. Comments. A food called lichen is part of the vegetation there, and people pick it from off the rocks. The landscape of the Shield has been levelled by many long periods of erosion and presents an even, monotonous skyline interrupted by rounded or flat-topped summits and ranges of hills. Fire has decreased albedo and net radiation in some northern regions (Liu, Ran-derson, Lindfors, & Chapin, 2005; Yoshikawa, Bolton, Romanovsky, Fukuda, & Hinzman, 2003), but not in others (Rouse & Kershaw, 1971). The Canadian Shield doesn't have many farms. Some of the trees are deciduous and some are coniferous. This type of forest is distinguished by long, cold winters and short, hot, wet summers. In the southern part, there are very cold snowy winters, while the summers are warm and long. The area shown is in the subarctic region and was eroded by glaciers during the last ice age. In between the mountains there are fertile valleys, lakes and rolling hills. The discussion that follows concentrates on . How much. For example; in northern areas you will see Coniferous trees, as you go south you will find more and more Broadleaf trees. Canadians extract copper, gold, nickel , zinc and lead from this area. Exploration and the Fur Trade -- Tales from the Canadian Shield -- Forests and Water -- Landforms -- Long Winters, Short Summers -- Charting the Climate -- Raging Fires -- Natural Resources -- Soil of the Canadian Shield -- Sparse . . The forest that makes up the Canadian Shield is known as a boreal forest or taiga. 2006 Mar;25(3):823-35. doi: 10. It's in the boreal and taiga vegetation region where a lot of coniferous trees grow. This is an overarching concern given that soil and water are cornerstones to all life on earth, as they provide the homes for most organisms and many of the nutrients, minerals and elements that are essential for . In addition, the soil is too thin to be of use as only a thin layer now covers the Canadian Shield. Farmers would . The Tundra: This area occupies one-fourth of the total area of the country. year -1 (Bickerstaff et al. The Canadian Shield. It is mainly composed of granite and has a thin layer of soil. Sitemap. The Canadian Shield is the ancient core of the North American Continent. Cotton grass, sedge, dwarf heath, shrubs, mosses and lichens are the most common vegetation in the Canadian Arctic (Aun et al. Intended to help secondary students understand the major physical features of each region, the . The Canadian shield is the exposed part of the North American craton, one section of the earth's floating crust. Comments. long and hot summers with mild winters, and plentiful precipitation (ideal for hardwood trees) Soil is similar to mixed forest, but contains more humus and less acidic properties. soil moisture and the vegetation canopy by changing soil properties, the energy budget and interception capacity (Burn, 1998). The vast forests consist of mainly Birch, Aspen, Tamarack, Spruce, Willow, Hemlock and Pine trees. The boundaries of these regions are not usually sharp lines on the landscape but are broad transition areas. The Canadian Shield has a variety of climates. The underlying bedrock largely determines the vegetation diversity of this landscape by creating dry, soil-poor . The Canadian Shield makes up most of the Boreal Shield, and was once a Precambrian mountain. The Canadian Shield is made up of deep-rooted mountains and spruce, lakes, bogs, and rock. As a result, there is little soil and sparse vegetation, so that is exposed. The Canadian Shield is mainly covered in trees, deciduous and coniferous. The lowlands of the Canadian Shield have a very dense soil that is not suitable for forestation; it also contains many marshes and bogs ( muskegs ). Many forests exist in the Canadian Shield. It is the coldest and deepest and because it has a cooler climate and poor soil conditions it is the least polluted. These two factors largely determine the patterns of soil and vegetation in the region. The bedrock, being quite impervious to water, prevents rainfall from penetrating all that deep and results in large areas of shallow lakes, swamps, and exposed rocky outcrops. 1. Figure 10.1CC BY (Attribution) license. . Beneath the Niagara Falls is the Pre-Cambrian rocks of the Canadian Shield the crescent-shaped basement of our continent. Canadian Shield is a large area of Precambrian rock that forms the core of Canada. . . There isn't much good farm land, because of the thin soil, with an exception of northeast Ontario and areas in Quebec. Relative Ages of Igneous and Metamorphic Rocks in the Canadian Shield. Because of the abundance of rocks, the erosion of the soil, and the glacial scraping of the land, the Canadian Shield has thin soil making it difficult to use for agricultural purposes, however the vegetation there has adapted to survive. The Canadian Shield. The southern part of the Boreal shield has met the Mixed wood Plains therefore making the vegetation Deciduous. As you go The correspondent to natural vegetation region of the Boreal Shield is the Boreal and Taiga forest. The Canadian shield was formed during the Precambrian era. VEGETATION Vegetation in the Canadian Shield is mainly coniferous forests. It comprises of northern coasts and all islands of Canadian Archipelago, which is often referred to as . It is composed mainly of highly metamorphosed granite, with smaller areas of metamorphosed sedimentary and igneous rocks and some areas of relatively horizontal but still quite ancient sedimentary rocks. The vegetation here is quite different from the rest of Canada. When we pollute our air, we are also polluting the precipitation that falls into water bodies and soils. 1. Get Started. 2) Minerals - this makes a lot of sense because the Shield is solid rock. In the southern part of the Interior Plains, no trees exists instead there is only grass and herbs. As the smallest Natural Region in Alberta, the Canadian Shield is a landscape shaped by granite bedrock exposures, sparse vegetation, coarse glacial deposits and countless lakes The Canadian Shield Natural Region is a remote landscape within Alberta that has a relatively little disturbance. The Canadian Shield is the ancient core of the North American Continent. Many would consider the Podzolic soils to be the most visually striking of Canadian soils. It is a leached soil profile because of the large amounts of precipitation. It is the world's largest continental shield covering 8 million square km (3 million square miles) and mostly consists. Vegetation: The vegetation of Canada, like the soil varies with the climate. The main type of vegetation is grasslands which includes . The Canadian Shield underlies the eastern and north-eastern portion . The Prairie Provinces are underlain by approximately igneous and metamorphic rocks of the Canadian Shield and sedimentary rocks (Figure 10.2). This is called the "tundra". Vegetation The plants of the Canadian Shield are different from the rest of plants in Canada. The Canadian Shield is one of the largest geologic continental shields in the world. relatively flat with rounded hills (that used to be mountains) store house of Canada's metallic minerals (lead, nickel, copper, ziinc, gold) gouged the bedrock, which eventually became lakes and rivers. Shaped somewhat like a horseshoe, or like the shields that ancient warriors used to . Mining is the connected industry. Both landforms and climate affect the distribution of plants, animals, and soils. The Arctic Cordillera consists of Precambrian rock, which is . The vegetation here endures the coldest of climates; the annual mean temperature in this zone is below negative with fewer than 50 growing days a year. . Natural Resources / Industries in the Canadian Shield Region today: 1) Furs - from fur bearing animals (hunting and trapping is still a large industry). It ranges from alpine tundra to coastal rainforest to grasslands and savannah forests. Temperatures in the winter range from -18 to -20* Celsius. There are lots of beatiful forests and rocky soil in the Canadian Shield.
