Vegetation

The natural vegetation of this climate is the evergreen coniferous forest which is called 'Taiga' in Russia. The species of the trees are spruce, pine, maple, fir and cedar. They are cone-shaped with short and drooping branches. Their leaves are like a needle so that they can prevent water loss. Their shallow roots absorb enough water when there is ice-melting. The wood of the trees is soft and very useful. It is used for making pulp for paper, matches, plastics, etc.

Animals

Very few animals live in this cold dry climate. They are small, sturdy and have short tails and ears. The body is covered with thick fur which protects them from cold. The main species of wild beasts are bear, beaver, squirrel, minx and lynx.

 

 

Tundra Climate

Position and Distribution

The Tundra climate region is located beyond 60°N and 70°N latitudes around the pole in the Northern Hemisphere. The chief areas of this climate are the northernmost parts of Canada, Alaska, north-west Scandinavia, Iceland, Greenland and Siberia.

 

Climate

There is severely cold throughout the year. The temperature goes down below the freezing point. In some places it is below -35°C. Summer is short not more than three months long. Winter lasts for nine or ten months. Sun rays are very slanting. Rainfall occurs in summer and is not more than 25 cm. Heavy snowfall occurs in winter.
