  1. Land Biomes

  2. Tundra Found in parts of Canada, Alaska, and Siberia

  3. Tundra – “The Cold Desert” • Found at latitudes around the North Pole • Less than 25 cm (10”) precipitation yearly • Very cold year round -40ºC (-40ºF) in winter • Cold, dry, treeless region

  4. Tundra – “The Land of the Midnight Sun” • Winter lasts 6 to 9 months with no daylight • Summer is short and cold with 24 hours of sunlight a day

  5. Tundra- • Soil is poor • Permafrost • Layer of permanently frozen soil

  6. Plants of the Tundra Tundra plants are resistant to drought and cold Examples: • Reindeer moss (a lichen!) • Lichens • True mosses • Grasses • Small shrubs and flowers

  7. Plants of the Tundra • Reindeer moss – It’s a lichen!

  8. Plants of the Tundra • Lichens

  9. Plants of the Tundra • Lichen

  10. Plants of the Tundra • True Mosses

  11. Plants of the Tundra • Small shrubs and flowers

  12. Plants of the Tundra • Small shrubs and flowers

  13. Plants of the Tundra • Small shrubs and flowers

  14. Plants of the Tundra • Grasses

  15. Animals of the Tundra Many animals of the tundra migrate there during the short summer Examples: • Biting insects • Snowy owls • Arctic hares • Caribou • Musk oxen • Lemmings

  16. Animals of the Tundra • Biting insects Mosquito Blackfly

  17. Animals of the Tundra • Snowy owl

  18. Animals of the Tundra • Arctic hare

  19. Animals of the Tundra • Caribou – “Reindeer”

  20. Animals of the Tundra • Musk oxen

  21. Animals of the Tundra • Lemmings

  22. Animals of the Tundra • Lemmings (lem-ing)

  23. Taiga or Coniferous Forest Found in parts of Canada, Alaska, and Russia

  24. Taiga or Coniferous Forest • World’s largest land biome • Latitudes between 50ºN and 60ºN

  25. Taiga- • Warmer and wetter than the Tundra • Winters are long and cold (-10º-14ºC) (14º-57ºF) • 35 - 40 cm (13”-16”) of precipitation yearly (mostly snow)

  26. Plants of the Taiga There is no permafrost, so trees can grow. Mosses and lichens grow on the forest floor. Examples: • Coniferous (Cone-bearing, Evergreen trees) • Firs • Spruces • Pines • Hemlocks • Cedars

  27. Plants of the Taiga • Fir tree

  28. Plants of the Taiga • Spruce tree

  29. Plants of the Taiga • Hemlock tree

  30. Plants of the Taiga • Liverwort (a moss)

  31. Plants of the Taiga • Mosses

  32. Animals of the Taiga Many animals live in the Taiga. Examples: • Moose • Black Bear • Lynx • Wolves • Badgers • Wolverines • Deer

  33. Animals of the Taiga • Moose

  34. Animals of the Taiga • Black bear

  35. Animals of the Taiga • Lynx

  36. Animals of the Taiga • Wolf

  37. Animals of the Taiga • Badger

  38. Animals of the Taiga • Wolverine
