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 ]
Taiga or tayga (/ ˈ t aɪ ɡ ə / TY-gə; Russian: тайга́, IPA:), also known as boreal forest or snow forest, is a biome characterized by coniferous forests consisting mostly of pines, spruces, and larches. The taiga or boreal forest is the world's largest land biome. [1]
Boreal forest near Shovel Point in Tettegouche State Park, along the northern shore of Lake Superior in Minnesota. A boreal ecosystem is an ecosystem with a subarctic climate located in the Northern Hemisphere, approximately between 50° and 70°N latitude.
60% of the land in the European Union part of the region is covered by forest, but most of this is commercial plantings. Less than 5-10% of the forest is old growth. The typical western taiga forest contains Norway spruce (Picea abies) and Scots pine (Pinus sylvestris) growing on shallow soil covered in moss, lichen and ericaceous shrubs. [1]
The Scandinavian and Russian taiga is an ecoregion within the taiga and boreal forests biome as defined by the WWF classification (ecoregion PA0608). [1] It is situated in Northern Europe between tundra in the north and temperate mixed forests in the south and occupies about 2,156,900 km 2 (832,800 sq mi) in Norway, Sweden, Finland and the northern part of European Russia, being the largest ...
In the far north, a band of Arctic tundra encircles the shore of the Arctic Ocean. The ground beneath this land is permafrost (frozen year-round). In these difficult growing conditions, few plants can survive. South of the tundra, the boreal forest stretches across North America and Eurasia.
Because the island is young and isolated from larger land masses, species biodiversity is relatively low. Forest cover has been reduced to about 1% of the original birch forest by a long history of timber extraction and soil erosion caused by sheep grazing. Blanket bogs (areas of high rainfall and peat accumulation) are common. [1] [2] [3] [4]
