  • 1. Savanna
    Environmental Science
    3rd Period
    By: Eddie Riley, Nieem, Jordan Bowling, Robert Thoman
  • 2. Africa
    Shaded regions are the regions in Africa that are considered Savannas.
  • 3. Savanna Climate
    • Wet Climate
    The wet season lasts 5 to 6 months and lasts from December to March.
    The wet season is during the summer. The average temperature during the wet is about 85°F.
    • Dry Climate
    The dry season lasts 5 to 6 months, usually from May to October.
    The average temperature during the dry season is about 70°F.
    Through August and September the temperatures begin to rise as the sun moves more directly overhead.

  • 4. Abiotic Factors in Savanna
    • Abiotic Factors
    • 5. Almost every major geological and soil type occurs within the biome.
    • 6. Rainfall varies from 235 to 1,000 mm per year.
    • 7. Altitude ranges from sea level to 2,000 m.

  • 8. Biotic Factors
    • Biotic Factors (Plants)
    • 9. Senegal Gum Acacia
    This plant tends to grow in areas that are filled with grass and trees.
    This plant doesn’t really have any Predators, but Giraffes, antelopes and Elephants like to eat its leaves.
    The main source of food/energy for this plant is water and the sun.

    • Biotic Factors (Plants)
    • 11. Elephant Grass
    Tends to grow more in damp, wet areas. Dried out river beds are perfect.
    Farmers will cut this down to feed other animals.
    The main source of food/energy for this plant is water and the sun.

  • 12. Biotic Factors
    • Biotic Factors (Animals)
    • 13. African Elephant
    African Elephants tend to stay around grassy and dry areas.
    No animal is really going to try and eat and Elephant, but Lions, Jaguars and Leopards can eat baby elephants.
    Elephants eat different plants, trees and shrubs.
  • 14. Biotic Factors
    • Biotic Factors (Animals)
    • 15. Grants Zebra
    Tends to stay around grassy, dry and hot areas.
    Lions, Jaguars and Leopards are the main predators.
    They are Grazers, they eat shrubs, twigs, leaves, plants.
  • 16. Environmental Issues
    Natural Issues
    Seasonal fires play a vital role in the savanna's biodiversity.
    Human Disturbances
    Farmers have been over farming the savannah for years and if they keep on doing it. The ground won’t be able to grow and vegetation.
    Cattle rearing has been going on for more that 6,000 years in India and Africa and if the ranchers keep it up then we could have more green house gases then cars produce.
