ESSAY Earth & space science Semester 2: Taiga Region
Introduction
The boreal forest, also known as the Taiga region is the major life zone of vegetation that is composed of various trees, soils, flora, and fauna. The Taiga region reaches across the upper northern hemisphere. Thus following across Canada, Alaska, and northern New England: making this the largest land biome in the world. In this particular region, there are various types of soil, flora, and fauna that flourish. Also, as this is a giant turf of land, a large number of threats can occur, such as: human activities, climate change, and pollution. And with this many nations are taking many steps to protect it. Climate and Geography The Taiga region reaches across the upper northern hemisphere. Following across Canada, Alaska, and northern New England. It is the largest land biome in the world that comprises approximately 29% of the Earth’s forest cover. Mainly in Russia and Canada, which stretches 3,600 miles from the Pacific Ocean near Russia to the Ural Mountains. This region is entirely

In the forests of Taiga, the soil is likely to be youthful and defective in nutrients, this is due to the “lack of the deep, organically enriched profile that is present in the temperate deciduous forests” (Quoted from, Wikipedia, Taiga: Climate and Geography). In addition, thinness of the soil is the cause of the cold weather, that overtime can allow many of the nutrients to be carried into the plants with more ease. Many of the floras came from North America and Asian due to the connection of the Bering land bridge that allowed of number of animals and plants to be colonized in both continents. Lastly, there is a small range of fauna because of the harshness of the temperature. There are about 85 species of mammals, 130 types of fish, and 32,000 categories of
The Taiga Shield Ecozone is made up of wetlands, shrublands, meadows and open forests. This Ecozone is a subarctic region therefore, the cold temperatures make it hard for vegetation to grow. There are trees, such as the coniferous species black and white spruce, tamarack, and dwarf pines. Most of them are stunted and do not reach full growth because of the climate. The tree line is at the northern edge of the Taiga Shield Ecozone and beyond the tree line is where the arctic tundra is. The soils found in this Ecozone are very thin and highly leached. The Taiga Shield has igneous, metamorphic and, sedimentary rock. These types of rocks are located in the Taiga Shield because of the volcanoes that formed it originally and the
larger vegetation zones to the way we should understand the ecology of the land scape.
Canada is a country filled with different and diverse ecozones. Two ecozones in Ontario are the Boreal Shield and the Mixedwood Plains. The Boreal Shield covers a large portion of Canada. It has a lot of wooded areas and holds a small amount of Canada’s population. The Mixedwood Plains is Canada’s smallest ecozone. Even though it’s small, it holds much of Canada’s population. The Mixedwood Plains is a better place to live than the Boreal Shield based on its urban population, its more comfortable climate and its strong economic base.
A forest is filled is diverse types of vegetation with in the forest such as mosses, ferns, and wild
Canada's Boreal is one of the last boundary forests left in the world. It provides vital assistance that humanity relies on.
My biome is the Taiga. One place the Taiga can be found is Oslo,Norway. Some abiotic factors in the Taiga are rain, sunlight, soil, temperature, and wind. Some biotic factors are moose, black bears, wolves, moss, and pine trees. Those abiotic and biotic factors interact a lot. There are four levels of organization. They are species, population, community, and ecosystem. An ecosystem is all the biotic and abiotic factors in a specific place. An example of a ecosystem in the Taiga is spruce trees, pine trees, mushrooms, owls, and bears. Those are only a few of the abiotic and biotic factors that make up the Taiga.
In the Taiga biome, the animals living there can survive through the cold and snowy climate of the biome. The Gray Wolf or the Timber Wolf is the top of the food chain and is the largest wild canine. The Gray Wolf lives in the forests of the Taiga Biome and is part of a species of lupus. The River Otter inhabits the swamps, lakes and rivers of the Taiga Biome. The River Otter also inhabits the woods in the Taiga Biome. River Otters are a species of canadensis and are also omnivores so they eat both plants and animals. The Snowshoe Rabbit or also known as the Varying Hare also lives in the forest areas of the Taiga Biome. Snowshoe Rabbit is found mostly in the higher parts of North America and they migrate throughout the midwest United States.
Malcolm X is the most influential person ever. He showed significance by impacting nationalism, self defense, and power for black people during the civil rights movement. “There is no better than adversity”. Every defeat, every heartbreak, every loss, contains it’s own seed, it’s own lesson on how to improve your performance next time.” Says Malcolm X in a speech.
Forest ecosystems cover around 31% of our land across the world; they produce vital supplies from oxygen to logs for the production of paper and furniture such as tables.
"Showing a great deal of variety; very different ". Not only is that the definition of diverse, but it is also a description if Canada. Canada is described like this because it is so different from other places in terms of physical characteristics, population, and natural resources. Due to these factors Canada is unlike other places but in a good way.
Southeast Alaska contains 10.9 million acres of forest land. Forty percent of southeast Alaska’s forest land or 4.4 million acres is reserved federal land and includes National Park Service or U.S. Forest Service lands, national forest wilderness areas, and federal game refuges (Campbell et al. 2004). The coastal rainforest of southeast Alaska spans across the majority of the coast and at KLGO, the coastal rainforest spans from sea level to around 3500 feet in elevation. Southeast Alaska receives high levels of annual precipitation and coniferous trees dominate the area, although Skagway receives less precipitation compared to the rest of the region. Coastal rainforest vegetation around KLGO includes: western and mountain hemlock, Sitka spruce,
The Great Bear Rainforest has a lot of kelp forest which live in the lakes,these are living plants that are used to make asian seaweed and it also feeds certain wildlife there such as seals and other microscopic and life forms such as shrimp possibly.
The Aquatic biome is the most significant out of all of the five biomes. Water is essential and important for life here on Earth. It’s what we all need in order to survive. Water also supports life, and many different species live in it, or for some parts of their life. Since water covers one-thirds of the Earth, the temperature of the aquatic biome tends to be humid and slightly cool. It is fairly constant so it can be able to tolerate life. This region is filled with so many different species of animals some big and some even small. The Aquatic biome is broken into two regions freshwater and marine
A biome, also known as life zones, consists of all plants, animals, and other organisms, as well the physical environment in a particular area. A biome is characterized by its’ plant life, climate, and location. The climate and physical features determine the boundaries of a biome. A biome is made up of many different ecosystems. The ecosystems tend to have the same pants and animals as neighboring biomes around the boundaries. The major biomes are the tundra, taiga, tropical rain forest, temperate forests, desert, grassland, savanna, chaparral, and marine. Each biome has it’s own characteristics such as the tundra.
Physiologically, the country is divided into five regions, according to altitude (the Terai, the Siwalik, the Middle Mountains, the High Mountains and the High Himal). Of the total land area, forests cover 4.27 million ha (29.0 percent) and shrub covers 1.56 million ha (10.6 percent) (DFRS 1999). The annual rate of forest depletion in the Terai was 1.3 percent from 1978/79 to 1990/91. In the hilly area, forest areas have declined at an annual rate of 2.3 percent from 1978/79 to 1994. In the entire country, from 1978-79 to 1994, the forest area has decreased at an annual rate of 1.7%. This trend indicates the ongoing pressure on forest resources, especially in the Terai.
