Black Rhino

(Diceros bicornis)
IUCN RED LIST: Critically Endangered

Intensive anti-poaching efforts have had encouraging results since 1993, and the population now numbers around 5,500 in the wild.

The black rhino, is slowly coming back from horrendous losses. By 1993, fewer than 2,300 rhinos remained from populations of more than 65,000 in the 1970s. Today, black rhino numbers hover around 5,500 animals. They are also being hard-hit by poaching, but so far, are holding their own.

Biology
  • The black rhino lives in Africa, primarily in grasslands, savannahs and tropical bush lands.
  • There are four black rhino sub-species.
  • Black rhinos are browsers. Their prehensile upper lip is adapted for grasping and holding leaves and branches of shrubs and trees.
  • Black rhinos can live to be 30 - 35 years in the wild.
  • Gestation lasts approximately 15 - 16 months, and mothers give birth to one calf every 2.5 - 3 years.
  • Females and sub-adults generally are social, but bulls are typically solitary.
  • Adult female black rhinos have overlapping ranges and are not really as solitary as often portrayed. Males are generally solitary and may be territorial.
