African Rhinoceroses: Challenges continue in the 1990s
Despite the concern expressed and the measures taken by conservationists and wildlife authorities, the status of African rhinos has worsened during the last decade. The black rhino, Diceros bicornis, has continued to rapidly decline in number, resulting in further fragmentation and extinction of populations. Today most countries have fewer black rhinos than they had three years ago; the deaths represent a great loss of unique genes and adaptation to local environment. However, Kenya, Namibia, South Africa and Zimbabwe have stable populations and, although on the decline in Botswana and towards extinction in Mozambique, the southern white rhino Ceratotirerium simum simum has continued to show an overall increase.
