  1. Artic Tundra By: Lottie and Nate Arctic Tundra

  2. Map

  3. Characteristics • Northern Hemisphere, including North Pole • Extremely cold climate • Low biodiversity • Short season of growth and reproduction • Limitation of drainage • Simple vegetation structure, no deep roots

  4. Climate • Average summer 37-54 F° • Average winter -30 F° • Rainfall totals 6-10 in/yr.

  5. Seasonal Information Summer is the best time to visit the Arctic Tundra. The temperatures are manageable and animals are out of hibernation. Summer is the main breeding season for arctic animals, so you can see baby animals.

  6. Unique Features • Permafrost: underground soil that holds captured water for 2+ years. • Prevents water from soaking into the ground when snow melts during the summer marshes and ponds • Usually 5 feet deep

  7. Plant Species • Low shrubs • 400 different varieties of flowers • Crustose and Foliuce lichen

  8. Plant Adaptation • Plants have adapted to high winds and soil disturbances • Plants group together • Short in height • Can carry out photosynthesis in low temperature and low light intensities

  9. Animal Species • Herbivore • Lemmings, caribou, arctic hares • Carnivore • Arctic foxes, wolves, polar bears • Migratory Birds • Ravens, falcons, loons • Insects • Arctic bumble bees • Fish • Cod, flatfish, salmon, trout

  10. Animal Adaptations • Animals have adapted to withstand cold winters • Breed and raise young quickly in the summer • Additional fat insulation • Many animals migrate or hibernate during winter

  11. Visit the Tundra! • Best season to visit is in the summer, many national parks are closed during winter • Tours • Car, motorcycle, helicopter, snow mobile • National parks offer great hiking trails • Over 20 National Parks in Alaska

  12. Environmental Concerns • Ice and glacier melt • Warming by .5 degrees each decade
