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]
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 ...
Beaver, Canadian lynx, bobcat, wolverine, and snowshoe hare are all keystone species in the taiga area. These species are keystone because they have learned to adapt to the cold climate of the area and are able to survive year-round. These species survive year-round in taiga by changing fur color and growing extra fur.
The species within boreal ecosystems varies as it consists of both terrestrial and aquatic habitats. The species composition include many generalized and less specialized feeders. [ 4 ] From the equator to the poles, species richness decreases, and there is a negative relationship with species richness changes as climate changes.
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.
The Southern Hudson Bay taiga is a terrestrial ecoregion, as classified by the World Wildlife Fund, which extends along the southern coast of Hudson Bay and resides within the larger taiga biome. The region is nearly coterminous with the Hudson Plain , a Level I ecoregion of North America as designated by the Commission for Environmental ...
The Okhotsk-Manchurian taiga ecoregion (WWF ID: PA0606) is an area of coniferous forests in the Russian Far East, covering the Amur River delta, the west coast of the Okhotsk Sea, and the rugged extension of the northern Sikhote-Alin Mountains that run southwest-to-northeast through the Primorsky and Khabarovsk regions. It is the southernmost ...
The plant life here is varied for Alaska, composted of a mixture of conifers and other trees, shrubs, and herbs. The dominant trees in this region are black spruce (Picea mariana), white spruce (Picea glauca), lutz spruce (Picea x lutzii), quaking aspen (Populus tremuloides), balsam poplar (Populus balsamifera), black cottonwood (Populus trichocarpa) and paper birch (Betula papyrifera).
