Taiga
Facts
In
the taiga, the average temperature is below freezing for six months of
the year. Total yearly precipitation in the taiga is 12 - 33 inches (30
- 85 centimeters). Although the cold winters have some snowfall, most of
the precipitation comes during the warm, humid summer months.

Because of the tilt of the earth on its axis, in the taiga
you'll find long nights in the winter and long days in the summer.
During the summer months, the taiga fills up with millions
of insects. Birds, who eat insects, migrate every year for the plentiful
food supply.
The taiga is prone to wildfires. Many trees have adapted
to this by growing thick bark, which can protect a tree from a mild fire.
Decomposition
Because of cool temperatures decomposition is slow in
the taiga. Undecayed vegetation builds up on the forest floor, making it
feel like a sponge. Since decomposition is slow, the soil is thin and lacking
in nutrients. Trees grow taller where warmer temperatures allow for faster
decompostion or by streams and rivers which carry nutrients from higher
ground.
