There is a fair amount of precipitation, but it is usually in the form of snow, not rain. These cold conditions create a unique vegetative habitat that is not found in warmer regions on the planet. Most of the forest consists of different species of Larch, which is a genus of coniferous cone-bearing trees.
Larch trees are not evergreens, but are deciduous, which means they loose their needle-shaped leaves during parts of the year. Image credit: Creative Commons. This truly vast area is bordered by the Yenisei River to the west and the Verkhoyansk, Kolyma and Dzhugdzhur Mountain ranges to the east.
The climate is subarctic and strongly continental—from September until April the Siberian anticyclone causes bitterly cold, dry conditions. In the southwest, average monthly temperatures are The average annual temperature is In the northeast of the ecoregion, the average annual temperature has dropped to Most of the ecoregion lies in the zone of permanent permafrost.

A biome is an area classified according to the species that live in that location. Temperature range, soil type, and the amount of light and water are unique to a particular place and form the niches for specific species allowing scientists to define the biome. However, scientists disagree on how many biomes exist. Some count six forest, grassland, freshwater, marine, desert, and tundra , others eight separating two types of forests and adding tropical savannah , and still others are more specific and count as many as 11 biomes.
Use these resources to teach middle school students about biomes around the world. A terrestrial ecosystem is a land-based community of organisms and the interactions of biotic and abiotic components in a given area. Examples of terrestrial ecosystems include the tundra, taigas, temperate deciduous forests, tropical rainforests, grasslands, and deserts.
The type of terrestrial ecosystem found in a particular place is dependent on the temperature range, the average amount of precipitation received, the soil type, and amount of light it receives.
Use these resources to spark student curiosity in terrestrial ecosystems and discover how different abiotic and biotic factors determine the plants and animals found in a particular place. Trees are important because they provide valuable commodities, including wood, paper, and fruit.
However, forests are not distributed equally around Earth, and there are economic and social implications of some regions having more timber resources than others.

Arctic Circle. Also called taiga. Huge areas of wilderness host brown bears, grey wolves, Eurasian lynx, reindeer and sable. The Lower Dvuobje wetlands are home to the hauntingly beautiful, critically endangered Siberian crane. The flagship species of the West Siberian Taiga ecoregion is the Siberian flying squirrel.

The Ob River flows from the southeast to the northwest of the ecoregion. The north is bounded by tundra and the south of the ecoregion bordered by hemiboreal forests. The climate is subarctic with a mildly continental influence.
