Taiga
This is a biome prevalently characterized by conifer
forests that stretch out in the northern hemisphere and occupy the
northern regions of Europe, Asia and northern America. The taiga,
delimited to the north by the biome of the tundra, covers the
sub-arctic regions of the planet. The continental cold climate of
these areas, characterized by long, rigorous winters and brief dry
summers, makes the vegetation of the taiga less diversified in
comparison to that of other biomes. The arboreal species that are
more diffused are therefore pines, firs (above all red and Siberian
firs) and the larches, whose leaves in the form of needles and
pyramidal crowns allow them to bear the intense snowfalls; there are
also, however, forests of birch trees, poplars and alders. In the
brushwood are prevalently found heathers and mosses. The taiga hosts
numerous animals, among which big mammals such as the bear, the elk,
the reindeer and the wolf; but also animals of more modest size such
as the lynx, the wolverine and the sable. Among the birds,
crossbills and nutcrackers are common in the taiga and usually
frequent the forests of conifers.
