Ecologists estimate that the African white and/ or black rhinos might go extinct in ten years if the rate poaching does not slow down. While the African black rhino and the Indian rhino numbers are stable, at 5600 and 3700 respectively, the Sumatran rhino is extinct in Malaysia, only occurs in Indonesia now and numbers less than 80 individuals. The Javan rhino has is even closer to extinction with less than 60 individuals and only occurs in Ujung Kulon National Park in Indonesia. However the rhino that has been hit the hardest with poaching is the white rhino – this has been because the white rhino had made a amazing species recovery from the 1970s and 80s poaching and had increased its population to over 21,000 individuals. This species is also easily found in its habitat as it spends its time in open grassy areas, which is why the majority of the killed rhinos have been white rhino.
