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 boreal forest zone consists of closed-crown conifer forests with a conspicuous deciduous element (Ritchie 1987). [4] The proportions of the dominant conifers (white and black spruces, jack pine ( Pinus banksiana Lamb.), tamarack, and balsam fir) vary greatly in response to interactions among climate , [ 5 ] topography , soil , fire , pests ...
Brown bears are among the largest and most widespread taiga omnivores. The boreal forest/taiga supports a relatively small variety of highly specialized and adapted animals, due to the harshness of the climate. Canada's boreal forest includes 85 species of mammals, 130 species of fish, and an estimated 32,000 species of insects. [37]
The region is on the divide between European and Asian ecoregions, and also the meeting point of tundra and taiga. It is in the Palearctic realm, and mostly in the Boreal forests/taiga ecoregion with a Humid continental climate, cool summer climate. It covers 174,565 km 2 (67,400 sq mi). [1]
The Kamchatka Taiga ecoregion (WWF ID: PA0604) is a "conifer island" in the middle of the Kamchatka Peninsula, along the Kamchatka River. It is the easternmost example of Siberian taiga. The region has unusual ecological conditions, a "snow forest" that combines low temperatures, high humidity and boreal forest with heavy snowfall.
The coniferous forest goes by many names, including: Boreal forest, fir-spruce forest, the North Woods, and the taiga. It is noted in New England for its "harsh" conditions such as cold, subarctic temperatures, a short growing period, sandy-gravely acidic soil, and a high rate of leeching of nutrients out of the soil.
This region is characterized by two biomes: taiga (or boreal forest) and tundra. [2] While the taiga has a more moderate climate and permits a diversity of both non-vascular and vascular plants, [ 3 ] the tundra has a limited growing season and stressful growing conditions due to intense cold, low precipitation, [ 4 ] and a lack of sunlight ...
The tundra sub-zone contain one domain, the forest tundra domain. It is the ecotone between the boreal zone and the Arctic zone, and extends roughly from 55° to 58° north. Shrubby heathland with shrubs and lichens has patches of forest in sheltered sites, mainly stunted black spruce less than 3 metres (10 ft) high.
