Transcript of Tundra
The only tree that grows in the Tundra is the dwarf willow. The average height of the tree is 4 inches.
During the "summer ( May to July )" of the Tundra the sun is out for almost the whole day, including midnight.
Artic Poppy is a plant in which it's stems help store water and keep the plant warm. The plant is always facing the sun because that's what gives it warmth which helps the plant produce more seeds.
Cushion plants are plant that grow in tight clusters and look like mini cushions. Cushion plants are common in the Tundra and carry on photosynthesis from the short daylight they receive.
The Arctic Hare is one of the most opportunistic species of the Tundra. They live rocky outcrops or hillsides with crevices to protect them from the extreme weather and predators. They can also be mistaken as snowshoe.
The Lemming is a the rodent of the Tundra. It is herbivorous, feeding on grass and shrubs, and occasionally larva. Their long soft fur protects them from the cold.
The Tundra climate changes very little in the summer time,it ranges from 45 to 50° F. The sun barely gives of any warmth for the 24 hours it shines in the Tundra. The day and night are about the same temperatures with it being slightly colder at night.
The Tundra's soil is basically a layer of permafrost and dry ground. The soil does not allow the penetration of water to seep through because it is so rough and hard. So it gives plants a hard time to survive. Although the plants do survive of off dead organic matter from the previous season. The soil is also fragile which turns disturbed ground, to sinkholes and the loss of scarce top soil.
Two species of Arctic Fox are at risk of being endangered because of fur hunters in Norway, Sweden, Finland, and the Kola Peninsula. The other species is in Russia due to a parasite spread from dogs.
The Caribou in Queen Elizabeth Islands of northern Canada, and the Northwestern coast of Greenland are at risk of being endangered. They are at risk of being endangered because of their food diet.
The Musk Ox was at risk of being endangered in 1917 because there were only 500 of them. Now there's over 40,000, which puts them off the endangered animal species list.
The Polar Bear are at risk of being endangered due to the climate change. The Polar Bears habitat is know melting which causes their shelter and food to decrease.
Humans are begging to raise their concerns about the Tundra because of the global warming incidents. We have built national parks to preserve the wildlife and environment of the Tundra. The human population worldwide of the Tundra is about 100,000. Although humans have a somewhat positive affect on the Tundra, there still is a negative affect too. Hunters hunt here for food and fur, killing the animals that belong there. As humans we need to be respectful of our nature and wildlife because they have life's too.
