  1. Biomes. Part II Tundra and Boreal Forest Science 8 10/07

  2. Tundra • Tundra means: “Marshy Plain” • Landscape: treeless,dotted with lakes, ponds and bogs • Liquid water available only 2 to 3 months a year. “artic desert”

  3. Tundra • Location: encircles the top of the world. • See map.

  4. Tundra Permafrost: the ground is permanently frozen. Only the top layer thaws in summer. Summer means a lot of water on the surface.

  5. Producers of the Tundra • Not much species diversity. • Plants complete their life cycles in the very short summer months. • Lichens, mosses, sedges, grasses, dwarf willows

  6. Producers of the Tundra

  7. Consumers of the Tundra • More consumer diversity in summer • Migrating summer birds: ducks, geese, shore birds. Most take advantage of area for nesting

  8. Consumers of the Tundra • Year round resident • Mammals: polar bears, musk ox, snowy owls, artic fox. • All animals suited for long winter. Long coat, white

  9. Consumers of the Tundra

  10. Boreal Forest • Also known as the northern coniferous forest. • Made up almost completely of spruce trees and fir trees.

  11. Boreal Forest • Also known as Taiga • Location: Lies south of tundra covers broad zone across North America Europe and Asia.

  12. Climate of the Boreal Forest • Closer to the equator receives more energy from the Sun. • More snowfall insulates the ground no permafrost. • Still cold

  13. Producers of the Boreal Forest • Waxy coating on needle shaped leaves prevents damage from cold and water loss during long winter. • Few plants on forest floor. Not enough sun light • Some birch, willow and aspens

  14. Producers of the Boreal Forests

  15. Consumers of the Boreal Forest • More diversity in plant species means more diversity in animals • Moose, Beaver, Wolf, Seed Eating Birds, Red Squirrels, Voles, Summer Insects

  16. Consumers of the Boreal Forest
