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.
The subarctic climate (also called subpolar climate, or boreal climate) is a continental climate with long, cold (often very cold) winters, and short, warm to cool summers. It is found on large landmasses, often away from the moderating effects of an ocean, generally at latitudes from 50°N to 70°N, poleward of the humid continental climates .
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] Insects play a critical role as pollinators, decomposers, and as a part of the ...
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 effects of increased temperature on boreal forest growth have varied, often depending on tree species, site type, and region, as well as whether or not the warming is accompanied by increases or decreases in precipitation.
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 ...
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.
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 local ecology is also affected by volcanic activity. [1] The region is about 300 km long (north–south), and averages about 100 km west–east. [2]
