KEYSTONE SPECIES-ELEPHANTS (HERBIVORY PREDATOR)

Elephants native to African grasslands (savannas). Without the presence of elephants, grasslands would probably develop into forests. Elephants graze on trees such as acacias, above, preventing them from growing to maturity. By eating small trees, elephants preserve the grasslands, because the grasses need plenty of sun to survive. If they were not there, the savanna would convert to a forest or scrublands.
