Vegetation: This biome has very characteric trees. Dominant trees in the tiaga are Needleleaf, coniferous (gymnosperm) trees. From a biodiversity standpoint, there is little diversity in the main trees. The four main genera found are: 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.
There are several other trees that can be found in this zone. They are early succesional trees (trees found in disturbed habitats that over time will be replaced by the climax community of spruce, firs and pines). The most common trees are the deciduous alder (Alnus), birch (Betula), and aspen (Populus).

The boreal forest corresponds with regions of subarctic and cold continental climate. There are long, severe winters (up to six months with mean temperatures below freezing) and short summers (50 to 100 frost-free days), as is a wide range of temperatures between the lows of winter and highs of summer.
