The Russian miracle
Taiga is
the largest type of forest on the Earth. Its huge territory accounts
for one-fifth of the world's total forested land and contains as much as
one-half of the world's evergreen forests.
The taiga is one of
the world’s largest terrestrial ecosystems. It is a great example of how
nature strives through the harshest of weather conditions.The word
taiga comes from Turkish and it means “coniferous forests.”
These
forests represent the largest, oldest and snowiest type of land
territory, covering extremely large areas in northern Russia, mostly
Siberia. In some places, the width of these forests reaches several
thousand kilometers. The taiga takes up about 11 percent of the Northern
Hemisphere.
Similar forests can be found in areas of Eurasia and
North America, and mountain regions of Northern Europe. The areas
covered by this type of forest are larger in Russia than anywhere else
in the world. The taiga is sometimes referred to as a Russian miracle.
Harsh climate
The taiga forests have one of the coldest biomes on Earth its temperatures vary considerably in the winter and summer.
The
temperature in the summer is usually around 10 degrees Celsius and
never higher than 20 degrees. Even though summers are mostly warm, they
are very brief - for a large part of the year, the sun does not rise too
far above the horizon. Winters last up to six months, with the average
temperature far below freezing.
Most of the year, however, the
temperature of minus 50 degrees Celsius is considered normal. The lowest
temperature that can be experienced in the taiga is said to be MINUS 68
degrees Celsius.
Those who have experienced the taiga, say living
there is cold and lonely. The spring and autumn are so brief, you
hardly know they exist at all.
Taiga flora and fauna - adapting to the weather

The
soil in the taiga is thin and poor in nutrients. This contributes to
the fact that most trees in the taiga grow close to the ground and
their roots don’t go too far into the soil. Even though the taiga is
mostly coniferous – dominated by larch, spruce, fir, and pine, some
broadleaf trees can also been seen here. For example birch, aspen,
willow, and rowan. A lot of the trees found in the taiga change their
biochemistry throughout the year, so they have the strength to better
resist freezing. Taiga is also no stranger to moss and bogs.
Nowhere
else in the world is there such a large number of furry animals than in
the taiga. Large herbivorous animals and small rodents are residents in
these forests – bears, weasels, raccoons, wolves, lynxes, rabbits and
squirrels. They are well adapted to the harsh weather.
Often, the
larger animals eat a lot during the warmer months, gain a lot of weight,
and then sleep through the colder months when they hibernate. The
animals that don’t hibernate generally become less active.
Brown bears are among the largest and most widespread across taiga.
About
300 species of birds spend summers in the taiga. Only about 30 species
stick around for the winter – the ones with more feathers to keep them
warm. The taiga produces an enormous amount of oxygen – it is said to
generate enough oxygen on its own to re-generate enough oxygen for the
entire planet.
Taiga in danger
One of the most
serious threats to the taiga is deforestation for human purposes. And
this practice has been on the rise in recent years. A lot of animals of
the taiga are hunted and trapped for their rich furs. This plays a major
role in the decline of their populations. Global warming is also a
reason for concern.
