Temperature & Precipitation
From this graph we can see that the taiga is a very cold place, with winters that have temperatures as low as -25 Celsius. Water availability is quite high, getting from 30-84 cm of rainfall annually. However most of it is snow during the winter months.
Taiga forest doesn't have very good soil. Because of the cold climate permafrost is very common in the soil. How the snow melts during the warm season but since the water cannot seep through the permafrost it creates soggy, damp soil near rivers and ponds.
Cross section of permafrost
Taiga forest in the summer get around 20 hours of sunlight a day however they get around 20 hours of darkness during the winter. This low amount of sunlight helps the taiga survive. The snow that falls during the winter is low but because of the low amount of sunlight it does not melt. This snow works as insulation and keeps the soil under it from freezing while the air above is freezing.
The canadian lynx and the snow shoe hare are have a very close prey/predator relationship. The hare is the lynx's main source of food. For this it has adapted to killing it very well. It's round feet allow to run on the snow very easily. The rare to has adapted to avoiding this predator by using camouflage. It has a white coat of fur in the winter and a darker brown one during the summer.
The taiga is an interesting forest. Many call it the forest of frost and fire. Between the season the taiga goes through drastic changes and these changes effect different species in different ways. In the winter the heavy snow acts as a layer of insulation, keeping small animals safe from the cold but at the same time bringing life into a standstill. In the summer the hot weather the forest runs dry. This is the time of forest fires. Forest fires bring forth new life. As the big forest burn down shrubs and smaller plants are able to flourish. The majority of these fires, 70% of them are cause by lighting strikes.
