The land north of Novosibirsk is essentially characterized by Taiga and Tundra biomes. The Taiga area experiences relatively low precipitation throughout the year (200–750 mm annually), primarily as rain during the summer months, but also as fog and snow; as evaporation is also low for most of the year, precipitation exceeds evaporation and is sufficient for dense vegetation growth. Snow may remain on the ground for as long as nine months in the northernmost extensions of the taiga ecozone.
Much of the area currently classified as taiga was recently glaciated. As the glaciers receded, they left depressions in the topography that have since filled with water, creating lakes and bogs (especially muskeg soil), found throughout the taiga.
Further north of the Taigas, is the Tundras, which has the typical permafrost, due to the rigorous continental climate of Siberia and the north half of the Far East .
In the European part of Russia, permafrost occurs only in the tundra and the forest-tundra zone. Its southern boundary goes from the Kola Peninsula to the mouth of the Mezen River and further on almost along the Arctic Circle to the Urals. In West Siberia, the permafrost border runs along the Enisei River near the River Podkamennaya Tunguska, where it sharply turns to the south and goes along the right bank of the Enisei River. To the east of the Enisei, the permafrost is spread almost everywhere, except for south Kamchatka, Sakhalin Island, and Primorjie.
