  • Soil and geography: in grasslands, the soil is red/yellow/grey or red/black clay. Grass-
    land soil has rich fertile upper layers.

  • Flora: vegetation is mainly grass, but trees can grow on the hills and along river beds.

  • Fauna: many types of grass-eating herbivores can be found in this habitat, such as
    black wildebeest, blesbok and eland. Rodents are also common in grasslands which
    makes this biome an ideal hunting ground for birds of prey. The diverse plant species
    also support many plant-eating insects such as butterflies, grasshoppers, crickets and
    ants.
