These ecosystems are commonly known as taiga and are located in parts of North America, Europe, and Asia. [1] The ecosystems that lie immediately to the south of boreal zones are often called hemiboreal. There are a variety of processes and species that occur in these areas as well. The Köppen symbols of boreal ecosystems are Dfc, Dwc, Dfd ...
Taiga (boreal forests) has amazing natural resources that are being exploited by humans. Human activities have a huge effect on the taiga ecoregions mainly through extensive logging, natural gas extraction, and mine-fracking. This results in the loss of habitat and increases the rate of deforestation.
Arctic ecology is the scientific study of the relationships between biotic and abiotic factors in the arctic, the region north of the Arctic Circle (66° 33’N). [1] This region is characterized by two biomes: taiga (or boreal forest) and tundra. [2]
These seven can be divided into two main groups. The northern regions of the boreal forest consists of four eco-zones – Taiga Cordillera, Taiga Plains, Taiga Shield and Hudson Plains – that are the most thinly treed areas where the growing season and average tree size progressively shrinks until the edge of the Arctic tundra is reached. [21]
This vast ecoregion is located in the heart of Siberia, stretching over 20° of latitude and 50° of longitude [1] (52° to 72° N, and 80° to 130° E). The climate in the East Siberian taiga is subarctic (the trees growing there are coniferous and deciduous) and displays high continentality, with extremes ranging from 40 °C (104 °F) to −65 °C (−85 °F) and possibly lower.
To the south is the Boreal Cordillera, to the east are the Taiga Plains, and its northern extent is defined by Yukon's coastline, at which it abuts the Southern Arctic ecozone. The northernmost area is an arctic tundra which is beyond the tree line , so is characterised by small plants and shrubs .
The Taiga Shield Ecozone, as defined by the Commission for Environmental Cooperation (CEC), is an ecozone which stretches across Canada's subarctic region. Some regions exhibit exposed Precambrian bedrock of the Canadian Shield , the oldest of the world's geological formations. [ 1 ]
This is a region of spruce taiga forest covering much of the central and northern interior of the U.S. state of Alaska and Yukon, Canada, from the Bering Sea and Beaufort Sea coasts to the Richardson Mountains in the east with the Brooks Range to the north and the Alaska Range to the south. This is an area of low hills and flatlands from sea ...
