Fun Facts

  1. A rhino's horn is not a true horn that is attached to the skull. It grows from the skin and is made up of keratin fibers, the same material found in hair and nails.
  2. The white rhino has a wide squared off lip that allows it to eat a wide swath of the green, short grasses that grow in the open savannahs.
  3. Unlike other rhino species, the white rhino is semi-gregarious; the females and sub-adults are rarely alone. The dominant male patrols the territory that the females and young pass through. Females in managed situations will reproduce better if they are in a group.
  4. During the European exploration of Africa, the white rhino was actually less numerous than the black rhino. In recent history the black rhino populations have been heavily poached to alarmingly low levels. Today, because of careful management in the Republic of South Africa, the white rhino population has increased dramatically. South Africa has approximately 80% of the world's population of white rhinos.

Ecology and Conservation

The white rhino is one of the largest pure grazers alive, making them an integral aspect of the southern African grasslands. Seed dispersal and the hindering of woody plant encroachment are important parts of their role in the grasslands.

People of some cultures believe that rhino horn contains medicinal or curative properties. The medical aspects are not proven but are still the primary reason for the poaching of the species. Because of education and awareness to the plight of the rhino many things are being done with varying degrees of success. Some of the conservation measures that have been attempted by some range countries are increased patrols by rangers, a shoot on sight policy for poaching, a dehorning program for rhinos, and the relocation of rhinos to safer areas.

Economic sanctions, or the threat of such, against countries that continue to consume rhino horn have had the greatest impact in their regulatory policies. Many of these countries have increased jail time and amounts of fines for those involved in the illegal trade in rhino horn.
