[2015] Arnav Podihetty: Taiga Ecosystem

In this biome, summers are short and mild and the winters are long, cold and dry. Rainfall, or precipitation, mostly falls as snow, usually 40-100 cm each year.

The average tempurature per year is 32 degrees fahrenheit

The average temperature reaches 10 °C for no more than 4 months in the year.Winter temperatures can be as low as -50 °C. The climate in the taiga is 32 degrees fahrenheit per year.

Taiga Ecosystem

Taiga, also called boreal forests, is the largest land biome. These forests are found in a broad belt across Europe, Asia and North America : about two thirds are in Siberia, and the rest are in Scandinavia, Alaska and Canada. The largest area of taiga is in Russia.

There is very little variation in the plants of this biome because they need to be hardy to survive the weather. Plants are mostly evergreen conifers with leaves like needles, such as pine, fir and spruce. Leaves like this minimise water loss, do not freeze and do not get weighed down with snow. The snow slides off the needles

The forest canopy lets in a restricted amount of sunlight, and this limits the understorey growth. The ground is covered with a thick layer of needles and dead twigs, matted together by fungus.

Animals found in taiga biome include woodpeckers, hawks, moose, bear, weasel, lynx, fox, wolf, deer, hares, chipmunks, shrews, and bats. Mammals living in the boreal forests have all adapted in various ways to survive the long cold winters. Generally they have heavy fur coats and many hibernate through the winter. Most are herbivores. However, the taiga is the habitat of the Siberian tiger, a carnivore and efficient hunter, the largest of the tiger family.

Climate Chart

Taiga is the Russian word for forest and is the largest biome in the world.

Animals that live here have certain characteristics that help them to survive:•They generally have thick fur or feathers to keep them warm. •Many animals have sharp claws and are good at climbing trees. •They have large feet to allow them to walk on the snow without sinking. •Many of them change colors from white fur in the winter, to help them hide in the snow, to brown fur in the summer, to help them hide in the trees.
