Black Rhino
Diceros bicornis
The Black Rhinoceros is a herbivorous browser that belongs to the order of the Perissodactyla. It’s one of the two species of Rhinos native to Africa and its current range includes Southern and Eastern areas of Africa. There are about 3,610 Black Rhino still left in the wild, but it has been estimated that there were about 70,000 in the late 1960's. The Black Rhino has seen the most drastic decline of all rhino species, because of poaching and habitat loss. But due to conservation efforts numbers are stabilizing and slowly rising, although tremendous effort is still needed to secure the future for the Black Rhino. There are four subspecies of Black Rhino, but the West African Black Rhino (Diceros bicornis longipes) is tentatively declared extinct.
