There is one kind of biomes named Tundra in Canada.Tundra is type of biome where the tree growth is hindered by low temperature and short growing seasons. The word " tundra" usually refers only to the areas where the subsoil is permafrost ,or frozen soil.Permafrost tundra includes vast areas of northern Russia and Canada .
The tundra biome is in the upper northern hemisphere,just below the ice-covered polar seas,at 60° to 70° north latitude.
Technically, there are three Tundra biome regions on Earth. First, the Arctic Tundra biome covers the Northern Hemisphere of Earth. It is just south of the polar seas and spans the northern hemisphere. See the Map below for more details. As you can see, it is has to be one of the coldest places on earth given its global location. The second biome region is the Alpine Tundra. It includes: American Cordillera (North and South America), the Alps and Pyrenees (Europe), the Rift Mountains (Africa) and a large portion of the Tibetan Plateau (Tibet). The third tundra biome is the Antarctic, located in the Antarctic region

Arctic tundra contains areas of stark landscape and is frozen for much of the year. The soil there is frozen from 25–90 cm (10–35 in) down, and it is impossible for trees to grow. There are two main seasons, winter and summer, in the polar tundra areas. During the winter it is very cold and dark, with the average temperature around −28 °C (−18 °F), sometimes dipping as low as −50 °C (−58 °F). During the summer, temperatures rise somewhat, and the top layer of seasonally-frozen soil melts, leaving the ground very soggy. The tundra is covered in marshes, lakes, bogs and streams during the warm months. Generally daytime temperatures during the summer rise to about 12 °C (54 °F) but can often drop to 3 °C (37 °F) or even below freezing. In Canada and Russia, many of these areas are protected.
Tundra tends to be windy, with winds often blowing upwards of 50–100 km/h (30–60 mph). However, in terms of precipitation, it is desert-like, with only about 15–25 cm (6–10 in) falling per year (the summer is typically the season of maximum precipitation).

Characteristics of tundra include:
Extremely cold climate,Low biotic diversity,Simple vegetation structure,Limitation of drainage,Short season of growth and reproduction,Energy and nutrients in the form of dead organic material,Large population oscillations.The tundra is cold and dark much of the year but has 24 hours of daylight each day during its brief summer.

Polar bear
Common Names: Sea Bear
Genus: Ursus
Species: maritimus
he Polar bear are the most recognised animal of the Tundra. Here are a fewadaptations that make them suitable to this biome: They have long stiff hair in between their feet that provide them traction. This also protects their feet from the cold. Their hair usually shakes free any water or ice from by swimming. These bears also have hollow fur, which traps air inside thus for making the bear buoyant. Their small rounded ears prevents water from entering the bears ear. This protects them from freezing water inside their ear and ear drum. They have a thick layer of fat which keeps them warm in the winters and it is up to 11cm thick. The skin under fur is black and this is for better heat retention. This thick lush white fur also gives them protection as they camouflage well with snow.

Arctic Fox
Common Names: Polar Fox, White Fox
Genus: Lagopus
Species: alopex
Arctic fox is one of the cutest animals in the tundra. Here are a few adaptations that make them suitable to this biome: They have short heavily furred, rounded ears (to protect from the cold). This limits the escape of body heat from the fox. Their coat changes color (in the summer the fur is reddish brown to act as a camouflage, and in the winter it turns white to blend into the snowy environment. It develops a layer of insulating fat to keep warm. They have a phenomenal breeding rate. They are able to remain active during temperatures of around -50 degrees celcus thus for making it possible to function and survive in extreme circumstances.

No trees grow here since the growing season is too short.Many plants grow close to the ground,where they absorb the warmth that has been trapped by the dark soil and are sheltered from the fierce wind.
Arctic Moss
Genus: Calliergon
Species: giganteum
Arctic Moss has tiny rootlets instead of roots due to the extreme permafrost. It also grows in lake bottoms and bogs and this iswhere it gets most of its nutrients from. It stores lots of the unused nutrients in the leaves for the next spring so it can grow again.
The Calliergon giganteum has adapted well to its cold climate. When it is not growing, it stores nutrients so new leaves can be made quickly next spring. The more leaves the more they can photosynthesize. It is adapted to the incredibly strong winds because it grows near to the ground. Because it can grow under water it is protected from the drying winds and cold, dry air of the frozen tundra. Its long life and slow growth are probably adaptations to the short growing season and the cold.

Caribou Moss
Common Name: Caribou Moss, Reindeer Lichen
Genus: Cladonia
Species: rangiferina
Parts Used: entire organism
Caribou Moss can go a long time without water. They just grow dry and go dormant when there isn't water and/or light. They can grow again after being dormant for a very long time. Caribou moss grows in arctic and northern regions around the world. It grows on the ground and on rocks. It looks like a foamy, gray-green spongy mass, and grows to be 1 to 4 inches high. The stems, or stocks, are hollow. Although it is called caribou moss, it is actually a lichen.
Lichen can survive for long periods of time without water. They just dry out and go dormant when there is little water or light. They can begin to grow again even after very long periods of dormancy.
