Much of the plant life on savannas is adapted to seasonal aridity.

African Savannas occur between forest or woodland regions and grassland regions. The climate varies, with an average temperature of 27°C with peaks of 30°C in April and October, and between 50 and 150 centimetres of rain per year. Flora includes:

• Acacia (Tree)
  • Loses leaves in dry season to conserve moisture
  • Leafy canopy in rainy season (flattened by winds)
• Baobab (Tree)
  • Stores water in trunk
  • Thick bark to protect it from fires in dry season
  • Long Tap roots to reach underground moisture
  • Few leaves to reduce water loss through transpiration
• Grass
  • Grow Quickly to 3 or 4 meters in clumps
  • Shoots die in dry season leaving only roots
• Low Shrubs
  • Drought resistant
  • Small
  • Thorns not leaves
