Characteristics of Tundra

● The Arctic tundra is a very harsh cold biome.

● It has very cold winters● The average winter Temp. -34° C

(-30° F),● The average summer Temp.

3-12° C (37-54° F)

RainfallThe average rainfall in the Arctic biome is 6 to 10 inches.

Effect on the Environment

The effect that humans have on the environment is that they can harm the species that live there by building by or on the land that species have lived on.

Polar bear

Polar bears are the largest land carnivores in the world, rivaled only by the Kodiak brown bears of southwestern Alaska. Polar bears sit at the top of the food chain in the biologically rich Arctic. The most carnivorous of the bear species, polar bears feed primarily on the fat of ice-dependent seals. The remains of these seals provide food for many other Arctic wildlife species, giving polar bears a vital role in their ecosystem.

Population

The World Conservation Union (IUCN) estimates that there are between 20,000-25,000 polar bears in the world.

SealHarp seals spend most of their time diving and swimming in the icy waters of the North Atlantic and Arctic Oceans. These sleek swimmers often hunt for fish and crustaceans at 300 feet (90 meters) and may dive to nearly 1,000 feet (300 meters). They are able to remain submerged for up to 15 minutes.

During mating season, females form large colonies on floating ice and give birth to young. Older seals return annually to pack ice to molt. They lose their pelts and top layers of skin and grow a new fur coat every year. Harp seals are sometimes called saddleback seals because of the dark, saddle-like marking on the back and sides of their light yellow or gray bodies of the adults.

Arctic Fox The arctic fox is an incredibly hardy animal that can survive frigid Arctic temperatures as low as –58°F in the treeless lands where it makes its home. It has furry soles, short ears, and a short muzzle—all-important adaptations to the chilly clime. Arctic foxes live in burrows, and in a blizzard they may tunnel into the snow to create shelter.

Ermine - Mustela ermineaAt full adult size total body length from head to rump is 170 mm to 330 mm.

Ermine are distributed all the way around northern part of the globe. They are found in the north temperate regions of Eurasia and North America. In the New World, they range from east to west in a broad belt from the Arctic Ocean and adjacent islands of the Canadian Archipelago southward into the northern United States. Ermine are absent from the Great Plains.

This is three natural beautiesOf the Arctic biome

Habitat The tundra is a terrestrial biome that is characterized by extreme cold,low biological diversity,long winters ,brief growing seasons,and life that only the hardiest plants and animals can survive in this environment.The vegetation that grows on the tund

ra is restricted to a low diversity of small,ground-hugging plants that are well-adapted to survive in nutrient -poor soils.

Plants that could be found in the arcticThe plants that could found in the arctic is

The flowering plants , arctic moss, arctic

Willow, bearberry, caribou moss, diamond-

Leaf willow, labrador tea, pasque flower,

Tufted saxifrage

What helps the plants survive in the arctic tundraPlants also have adapted to the tundra by developing the ability to grow under a layer of snow, to carry out photosynthesis in extremly cold temperature, and for flowering plants

populationIn physical geography,tundra is a type of biome where the tree growth is hindered by low temper and short growing seasons . the term tundra comes through Russian from the Kildin Sami.
