  1. Tundra By Katie Thompson And Katherine Francis

  2. Facts In the summer months, the sun shines all the time, even at midnight. The movement of the plates and the warming and cooling of the planet have caused the cold conditions that are present today. As the sea freezes, the salt rises to the surface as crystals called ice flowers. The only tree that grows in the Tundra is the dwarf willow tree. A layer of permanently frozen subsoil call permafrost is found in the Tundra. It consist of mostly gravel and finer material.

  3. Characteristics Extremely cold climate Low biotic diversity Simple vegetation structure Limitation of drainage Large population of oscillations Energy and nutrients in the form of dead organic material Short growing season

  4. Areas where Tundra can be found Arctic (northern hemisphere) • Canada, Alaska Alpine- High elevation of mountains around the world • Ex: Mt. Everest

  5. Producers Arctic Moss Dwarf Arctic Willow Bearberry

  6. Consumers Arctic Hare Wolves Arctic Ground Squirrel Snowy Owl Bear Eskimo Curlew Arctic Fox Lemming Caribou

  7. Tundra Food Chain }

  8. Natural Resources Uranium Oil

  9. Concerns Countries are exploring for oil and uranium which is damaging the land. 1/3 of the world’s soil bound Carbon is found in these regions. When the permafrost melts in the summer the carbon is getting released in the atmosphere. Global warming is causing the polar ice caps to melt which is causing many species to loose their homes

  10. Endangered Species Arctic Fox Grizzly Bear Fern Musk Ox Polar Bear
