In comparison with other biomes, however, the taiga has low botanical diversity. Coniferous trees are the dominant plants of the taiga biome. Very few species, in four main genera, are found: the evergreen spruce, fir and pine, and the deciduous larch. In North America, one or two species of fir, and one or two species of spruce, are dominant.
White spruce, black spruce and tamarack are most prevalent in the four northern eco-zones of the Taiga and Hudson Plains, while spruce, balsam fir, jack pine, white birch and trembling aspen are most common in the lower boreal regions. Large populations of trembling aspen and willow are found in the southernmost parts of the Boreal Plains. [12]
A boreal ecosystem is an ecosystem with a subarctic climate located in the Northern Hemisphere, approximately between 50° and 70°N latitude. 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 ...
Watersheds characterize much of the taiga ecoregion as interconnecting rivers, streams, lakes, and coastlines. Due to a cool climate, low evaporation levels keep moisture levels high and enable water to have serious influences on ecosystems. The vast majority of water in the taiga is freshwater, occupying lakes and rivers.
[1] [3] These transition to alpine tundra and lowland taiga in a southeastern arc across the zone. To the northwest are rolling hills, throughout which are found broad wetlands reaching the coast of the Beaufort Sea. The interior, comprising the Selwyn Mountains and Mackenzie Mountains, is primarily steep, mountainous terrain with sharp, narrow ...
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]
To the west it abuts the foothills of the Boreal Cordillera in British Columbia and southern Yukon, and the Taiga Cordillera further north. These two ecozones comprise the Mackenzie Mountains . Its northern borders are with the Southern Arctic ecozone in northeastern Northwest Territories, and the Arctic Archipelago Marine ecozone at the delta ...
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 ...
