Rhino horn trade triggers extinction threat The IUCN warns that other rhinos could follow saying Africa’s northern white rhino is “teetering on the brink of extinction” while Asia’s Javan rhino is “making its last stand” due to continued poaching and lack of conservation. The subspecies of the black rhino – which is classified as “critically endangered” by the International Union for Conservation of Nature’s (IUCN) Red List of Threatened Species – was last seen in western Africa in 2006. Conservation efforts are in place to help reduce rhino poaching and to protect the black rhinos of South Africa.Africa’s western black rhino is now officially extinct according the latest review of animals and plants by the world’s largest conservation network. It has been traded and exported to numerous Asian countries for medicinal uses, and Yemen to be used as jambiya dagger handles. Rhino horn has been an ingredient to traditional Chinese medicine for thousands of years, falsely believed to treat various ailments from epilepsy to fevers. The trade in rhino horn has increased exponentially, posing an even greater threat to the rhinos of Africa. Rhino horn has become a commodity valued more than cocaine. Small populations of the Southwestern black rhino are being developed, and a trans-located population of the eastern black rhino is established in the Addo Elephant National Park in South Africa. The species is under great threat, with the population having drastically declined from about 65 000 in 1970 to 2400 in 1995. The majority of black rhinos are found in South Africa, Namibia, Zimbabwe, and Kenya. The black rhino sometimes covers the dunghills of the white rhino with its own dung. Only during the cow’s oestrus cycle, will the bull move closer and can spend about 30 days with the cow. Bulls may kill younger bulls wandering into their area of land.

Black Rhino DietThe black rhino is a browser, feeding on trees and higher bushes. The black rhino is actually light grey of colour, but their skins are coated and coloured by the soil and mud in which they like to roll. The black rhino is smaller than the white, with bulls weighing up to 1200 kg and cows weighing approximately 800 kg. The black rhino has a pointed upper lip, a head held high for browsing (smaller than the white rhino), with rounded, cone-shaped ears. The appearance of the black rhino can be described by distinguishing it from the white rhino species, most distinctly by the shape of its upper lip, head, and shape of its ears. The western black rhino was declared extinct in 2011, and the black rhino species overall is under threat of poaching. There are four subspecies in Africa namely the southern central black rhino (Diceros bicornis minor) eastern black rhino (Diceros bicornis michaeli) southwestern black rhino (Diceros bicornis bicornis) and the western black rhino (Diceros bicornis longipes). © Roger de la Harpe NameBlack rhinoceros (Diceros bincornis sp).
