The woodland mix varies according to geography and climate; for example, the Eastern Canadian forests ecoregion (of the higher elevations of the Laurentian Mountains and the northern Appalachian Mountains) in Canada is dominated by balsam fir Abies balsamea, while further north, the Eastern Canadian Shield taiga (of northern Quebec and Labrador ...
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.
These seven can be divided into two main groups. The northern regions of the boreal forest consists of four eco-zones – Taiga Cordillera, Taiga Plains, Taiga Shield and Hudson Plains – that are the most thinly treed areas where the growing season and average tree size progressively shrinks until the edge of the Arctic tundra is reached.

This type of forest is also known as taiga, a term which is sometimes applied to the climate found therein as well. Even though the diversity may be low, the area and numbers are high, and the taiga (boreal) forest is the largest forest biome on the planet, with most of the forests located in Russia and Canada.
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 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.
Subarctic regions are often characterized by taiga forest vegetation as deciduous trees can't withstand the long winters, though where winters are relatively mild, as in northern Norway, broadleaf forest may occur—though in some cases soils remain too saturated almost throughout the year to sustain any tree growth and the dominant vegetation ...
