Week4

  1. 1. Boreal Forests
  2. 2. GEOGRAPHY <ul><li>Largest biome in the world </li></ul><ul><li>6.4 mil. sq. mi. </li></ul><ul><li>29% of the world's forests </li></ul><ul><li>Located below the tundra biome </li></ul>
  3. 3. CLIMATE <ul><li>Long winters </li></ul><ul><li>6 months below freezing </li></ul><ul><li>-65 to 30 F </li></ul><ul><li>Short summers </li></ul><ul><li>Warm, rainy and humid </li></ul><ul><li>20 to 70 F </li></ul>
  4. 4. INHABITANTS
  5. 5. Endangered Animals <ul><li>Beaver </li></ul><ul><li>Siberian Tiger </li></ul><ul><li>Wood Bison </li></ul><ul><li>Whooping Crane </li></ul><ul><li>Peregrine Falcon </li></ul><ul><li>Lynx </li></ul><ul><li>Grizzly Bear </li></ul><ul><li>Snow Leopard </li></ul>
  6. 6. World's largest storehouse of carbon Their biomass is so huge that in spring and summer worldwide levels of carbon dioxide fall and oxygen levels rise If disrupted large amounts of carbon dioxide will escape into the atmosphere resulting in worldwide temperature change
  7. 7. HUMAN IMPACT
  8. 8. Oil Mining Alberta's Tar Sands is the second largest in the world only to Saudi Arabia, so large you can see it from space
  9. 9. LOGGING 90% of logging done is by clear cutting. Taking large sections of the forest at once and then replanting with one type of tree the following year. It takes years if not decades for these trees to grow back and produce the canopy they once had
  10. 11. Conclusion <ul><li>The Boreal forests provide the earth with great resources but these resources should not be taken for granted. Decline in a single resource such as trees can have a great impact worldwide. Sending every living creature into a downward spiral that we my not be able to recover from. </li></ul>
