plants and animals
The boreal forest shelters more than 85 species of mammals, including some of the largest and most majestic—wood bison, elk, moose, woodland caribou, grizzly and black bears, and wolves—and smaller species, such as beavers, snowshoe hares, Canada lynx, red squirrels, lemmings, and voles.
Numerous species of shrubs, including willow, alder, and mountain ash

climate
Climate: 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.

The Boreal forest is chilly and if it would to go through global warming it will require much stronger protections if they are to survive global warming
precipitation
Precipitation
- Precipitation takes place in two forms in the taiga biome: snow and rain. Precipitation falls in the form of snow during winter months; the annual precipitation being 20 to 40 inches (50 to 101 cm). Rainfall in the taiga biome typically occurs in the moist summer, registering an average annual rainfall of 10 to 20 inches (25 to 50 cm). This brings the average precipitation in this biome to approximately 40 inches (101cm)
biodiversity
Boreal forests include numerous species of coniferous and deciduous trees, shrubs, grasses, and species of fungi and lichens. Large and small mammals have adapted to the harsh conditions of the boreal forest, and billions of birds breed in or migrate through the boreal forest each year. Biodiversity in the boreal forest is of global significance.

geographical distribution and soil condition
geographic distribution and soil condition
Most of the soils are strongly leached as a result of centuries of leaching and somewhat impoverished parent materials. The soils are generally strongly acid and the main soil process under this dominantly leaching climate is 'podzolisation' leading to podsolic soils. The extreme climate coupled with the strong soil acidity means that relatively few organisms exist in the soil and the turnover of organic matter is slow
Worldwide, the boreal forest covers 12 million km2 and accounts for about 1/3 of the planet's forests, making it one of the largest biomes in the world (Lakehead University 2007). Found between 50° and 60° northern latitude, just south of the Arctic circle, the boreal forest stretches over the northern hemisphere in a large, circumpolar band across Canada, Alaska, Russia, and Scandinavia.
