Boreal Forests/Taiga

Boreal forests, also known as taiga, are extensive forests found across northern regions such as Canada, Alaska, parts of the northern United States, and several countries in Europe and Asia, including Sweden, Finland, Russia, and Japan.

Boreal Forests/Taiga

Boreal Forests/Taiga

Can be found in Canada, Alaska, and parts of the northern contiguous United States. Sweden, Finland, much of Russia from Karelia in the west to the Pacific Ocean (including much of Siberia), much of Norway and Estonia, some of the Scottish Highlands, some lowland/coastal areas of Iceland, and areas of northern Kazakhstan, northern Mongolia, and northern Japan.


Biotic factors: Many conifer trees (evergreens with needles) grow in the taiga, eg: Evergreen spruce, fir, pine, and deciduous larch, or tamarack. Some broadleaf deciduous trees and shrubs also grow in Taiga, most common are alder, birch, and aspen.

Larch forests

Larch forests claim the thin, waterlogged substrate in level areas underlain with permafrost. These forests are open with understories of shrubs, mosses and lichens. In Alaska stands of Larix larichina are localized phenomena, but in Siberia east of the Yenesei River the extreme continentality and nearly continuous permafrost give rise to vast areas dominated by Larix dihurica.

Pine forests

Pine forests, in North America dominated by the jack pine (Pinus banksiana), occur on sandy outwash plains and former dune areas. These are low nutrient, droughty substrates not tolerated by spruce and fir.

TREES

Needleleaf, coniferous (gymnosperm) trees are the dominant plants of the taiga biome. A very few species in four main genera are found: the evergreen spruce (Picea), fir (Abies), and pine (Pinus), and the deciduous larch or tamarack (Larix). In North America, one or two species of fir and one or two species of spruce are dominant. Across Scandanavia and western Russia the Scots pine is a common component of the taiga.

Soil: Podzolization occurs as a result of the acid soil solution produced under needleleaf trees. The main soil order associated with the taiga is spodosol.

DECIDUOUS
