When collecting subspecies information on hunted birds, range states are encouraged to age the birds to generate age-ratio of harvest. Tundra and taiga are two biomes that exist in the far northern regions of the Earth. The soil in the taig… While both the tundra and taiga have lichens and mosses, many grasses and wildflowers grow in the tundra that are less common in the taiga.

Quel type de plantes poussent dans l'eau salée. In the winter, a heavy blanket of snow protects plants that are low to the ground. This biome of the north of Siberia, that has been called taiga, also appears in the region of the sea of the Hudson, in the north of Canada.

The taiga is a broad band of coniferous forests that lies across Europe, Asia and North America. Arctic tundra occurs in the far Northern Hemisphere, north of the taiga belt. In the tundra, summer lasts six to eight weeks. The ground, poor in organic substances, presents shortage of nutrients. Reindeer, which live in the tundra during the arctic summer, live in the taiga during the winter. The Scandinavian countries, Siberia and Canada present forests of firs, pines and larches, and of birches. Le sol de la taïga est très acide et pauvre en azote, ce qui rend la croissance difficile pour les plantes qui ne sont pas adaptées à l'environnement. Another major difference between the taiga and tundra is precipitation. Conifer needles are protected with a waxy coating that reduces water loss when the ground is frozen and no liquid water is available.
