Estimates vary widely. McNaughton, after repeated road counts, estimated 60-108 in the combined areas of Serengeti NP and Masai Mara GR. The Serengeti Ecological Monitoring Program's (SEMP) aerial survey of the woodlands of the Serengeti ecosystem produ
In 1975 a total ground count in the Lake Manyara National Park resulted in an estimate of 35-40 black rhinos. Between July 1975 and October 1978, 26 rhino carcasses were found. The Park is small, so probably most of the carcasses were found. The Park au
Sixteen black rhinos were translocated to Rubondo Island between 1963 an 1965, since when five carcasses, two of them calves, have been found. The low visibility in the forested areas makes rhinos difficult to see, but communal dung heaps, scratching mar
Mount Meru and its surroundings being densely forested, it is difficult to census rhinos there, but rangers' reports show that both the Arusha Park and the Mt Meru Game Reserve have lost nearly all their rhinos. Between March 1975 and October 1977 16 rhi
I have no first-hand information on the Mkomazi Game Reserve, bordering Kenya's Tsavo National Park, which is soon to be upgraded to a national park. According to the Game Department, very few rhinos may survive there, and it is doubtful if they still for
Aerial survey 1982. On behalf of the Tanzanian Rhino and Elephant Task Force a census was carried out in the Selous Game Reserve in Southern Tanzania in 1981. About 35% of the 55,000 km? Game-Reserve was surveyed and the results were compared with a su
Ngorongoro Conservation Area. Up to 1965 Fosbrooke estimated that only about three rhinos were poached annually in the Ngorongoro Conservation Area (NCA), all speared by Masai. In 1978 the estimate was over 25, mostly killed with rifles by non-Masai poac
Until a few years ago Tarangire was famous for its large rhino population. In 1974 a Mweka Wildlife College rhino census in the Park, using ground transects, gave an estimate of 250. Heavy poaching seems to have started here earlier than in the Serenget
Kenya in the last ten years has lost over 90 percent of its black rhinos and today fewer than 1500 survive in scattered populations.
Mount Meru and its surroundings being densely forested, it is difficult to census rhinos there, but rangers' reports show that both the Arusha Park and the Mt Meru Game Reserve have lost nearly all their rhinos. Between March 1975 and October 1977 16 rhi
Burigi and Biharamulo Game Reserves. These reserves west of Lake Victoria, together with the surrounding forest reserves, cover nearly 5000 sq km. An aerial survey was made in February 1980 and a ground survey in August. An aerial total count was carri
In October 1978 and October 1979 S. Makacha, staff scientist in the Ngorongoro Conservation Area, in a thorough ground survey of the Maswa Game Reserve, found 41 carcasses in the eastern half of the reserve, but saw no live ones. In several recce flights
Black rhinos are by nature solitary and have a low population density. They communicate with one another and orientate within the home range largely by scent marks. In a drastically reduced population the marking system cannot be maintained, so that intra-specific communication is greatly reduced and with it the chance of reproduction.
