Elephant management in East African reserves and national parks has become one of the urgent conservation problems of today. In this study of the African savanna elephant, Dr Sikes shows that two diseases of the heart and arteries, found only in lowland elephants, were directly associated with the degeneration of the habitat when elephant numbers began to build up in the Tsavo National Park in Kenya and the Queen Elizabeth and Murchison Falls National Parks in Uganda. The two diseases thus appear to be natural factors tending to limit the elephant populations in these reserves, and she suggests four lessons to be drawn from this discovery by those concerned with elephant management in national parks.
