African Savanna Basics



African Savanna highlighted on World Map
  • Tropical grassland dotted with trees and shrubs that covers over 25 African countries
  • Dry, but nutrient-rich volcanic soil due to the seven month dry season
  • Long dry season (winter) and short wet season (summer)
    • Warm temperature year-round and never drops below 20˚C

Plant and Animal Adaptation

Both plants and animals have adapted to their surroundings.
  • Plants:
    • Roots are extremely long and extend deep into the ground to reach groundwater 
    • Most trees have developed fire-resistant bark and have high water-holding capacities
    • Baobab tree
  • Animals: 
    • Alter their diets to fit with available food sources and can go long periods without food
    • "Grazers" and "browsers" learn to compete/work with with other species and use their size to their advantage
