Flora

Plants that could be found here


  • Rhode grass
  • Red oat grass
  • Star grass

Adaptation


  • Grasses roots are deep, which allow them to be unharmed during the fires in the dry season. They contain starch reserves, so after the fire they can regrow. Some plants have, what they call corky bark that is smooth and resonance that is fire resistant. Then some grasses have adapted to grow an inch or more during 24 hours during the rainy season.

Fauna

Animals


  • Giraffes
  • Zebra
  • Elephant
  • Hyenas

Adaptations

  • Larger animals are able to run fast enough to escape fire during the dry season.

  • Cavs of animals are born during rainy season and there's grass to be found, and mothers have plenty of milk.

  • Small animals dig holes to refuge from the fires created by the dry fire season.
