Taiga Forest Plants and Trees
Taiga forest is also known as boreal forest and northern forest as well. This forest occupies 17 % of total land of Earth. Taiga forest covers 26 % of total forest area on earth.
Life is very difficult in this forest. Cooling and loneliness is the major factors which make life arduous. During winter temperature of boreal forest goes down to -54 degree Celsius. This bone-chilling temperature makes life difficult for animals, birds and trees also.
In winter season many animals of taiga go to hibernate, many of them migrate to warmer areas and some other coordinate with the climate. Only 10 % of total 300 bird species of taiga stay there for winter.
Approx 32000 species of insects and 130 species of fish live in taiga. Taiga forest consists of very few genus of trees. Most of the trees which are found in taiga are evergreens. Trees of boreal forest has developed some skills to make life easier in this onerous forest.
Trees of taiga have thick bark with long, sharp, waxy needles. These trees don't loose needles all year long. The wax of these trees protect them in winter from freezing and drying out. On the other hand upper canopy of thick bark burns away in wild fires of summer. This makes taiga susceptible to wild fires which are very much common there in summer.
After burning thick bark of trees, sunlight reach easily to the ground of taiga and makes way for new plants to grow. Summers are normally warm, rainy and humid in taiga.
Temperature in summer goes up to 21 degree Celsius. This is the time when life comes to track. Summer is the growing season of boreal forest. Summers here last only for 50 to 100 days long. To save time trees immediately start photosynthesis after ending of freezing winter days of taiga.
Autumn and spring are almost finished here in taiga, they hardly get noticed. Many insect eating birds and reptiles also come towards taiga during this season.
Many predators and herbivores animals live here and flesh eating animals depend on their preys for the food. All insects, birds and animals play a major role in life cycle of taiga forest.
Taiga forest is spread in many countries and continents of the world including United states, Russia, Siberia, Canada, Scandinavia, Scotland, Finland, Iceland, Alaska, Norway, Sweden, Mangolia, Northern Kazakhstan and parts of Japan. Taiga forest is situated just under tundra on Northern hemisphere.
