Siberian forest near Irkutsk

The taiga is a biome--a biome is a type of habitat that is determined by a specific climate--which is located just south of the tundra biome.  It is characterized by coniferous (evergreen) forests, really just endless, endless expanses of forest. This covers much of Russia, especially Siberia.

The winters in the taiga are long and very cold (-65 to 30° F) with some snowfall.  The summers are short, warm (up to 70° F), rainy and humid.  Spring and fall tend to be almost non-existent.

The taiga does not have as many plant and animal species as some of the other biomes, but it does have insects--lots of them--especially in the summertime.

Most plants are coniferous trees, evergreens like pine, spruce, hemlock, fir and larch.  The Scotch pine is especially prevalent in Siberia.

The evergreens have long, thin waxy needles.  The wax gives them some protection from freezing temperatures and from drying out.  Evergreens don't loose their leaves in the winter like deciduous trees.  They keep their needles all year long.  This is so they can start photosynthesis as soon as the weather gets warm.  The dark color of evergreen needles allows them to absorb heat from the sun and also helps them start photosynthesis early.

Where there are some deciduous trees, they tend to be alder, aspen and birch.
