The latitudinal distribution of vegetation cover in Siberia
Komarov Botanical Institute of Russian academy of sciences Professor Popov str., 2,
The latitudinal changes of vegetation cover on the plains of Siberia are observed. In Western Siberia there are 4 zones (tundra and taiga, and forest-steppe and steppe only here), in Central and North-Eastern Siberia − only 2 zones (tundra and taiga).Tundra zone is represented by 4 subzones in Central Siberia; in Western and North-Eastern Siberia − by 3 subzones (there are no polar subzone). All 5 subzones of the taiga zone are distinguished both in Western Siberia and in the Central Siberia, but in the Central Siberia, forests are found in very high latitudes. The feature of the taiga zone of Western Siberia is high paludification. As a result, the vegetation of mires dominates over the zonal vegetation. Zonal West Siberian types are dark coniferous forests. Light coniferous forests predominate in the taiga zone of Central and North-Eastern Siberia. In the forest-steppe zone in Western Siberia forests are small-leaved − birch, aspen-birch (Betula pendula, Populus tremula). The abundance of mires is the feature of this zone, as well as in the taiga.
