  1. Tundra Ian D. Trevor W. Ivonne F.

  2. Location • Northern Hemisphere • Northern America, Canada, North Pole, Russia • Cold conditions • Winter: -34 degrees C. • Summer: 3-12 degrees C. • Sweeping Winds

  3. Vegetatation • Low Shrubs, sedges, reindeer mosses, liver warts, and grasses. • 400 varieties of flowers • Crutose and foliose lichen • Plants are adapted to sweeping winds and cold climates. • Deep roots: against winds • Reproduce budding • Can preform photosynthesis with little light.

  4. Animals • Herbivores: Lemmings, vole, caribou, arctic hares, and squirrels • Carnivores: Arctic foxes, wolves, and polar bears • Birds: Ravens, snow bunting, falcons, loons, and various species of gulls. • Insets: mosquitos, arctic bumble bees, flies, and moths • Fish: cod, flatfish, salmon, trout • Animals are adapted for cold winter • Thick hides, thick fur, blubber to insulate heat

  5. Endangered Species • Polar Bears • Are endangered because of the global warming and melting ice caps. • Their main prey is seal found under the ice, less ice fewer prey • Humans are trying to find newer technology and energy that reduces harm on the environment and ozone layer.

  6. Soil • Permafrost • 5-10 inches deep • Gravel finer soil • Reserves moisture for the plants

  7. Threats to the Biome • Thinning of the ozone layer • Gases and burned fuels thin the ozone layer melting ice caps. • Oil spills • Mining for resources and destroying the permafrost needed for plant species to survive.
