During the periods of full moon from May to October 1980, black rhinoceroses were censused at all the important waterholes in the Etosha National Park. The results indicate an increase in the rhinoceros population which was substantially higher than expected. However, the high population in the west, where in some areas apparent over-utilization of the available food resource was evident. has since been affected by drought, anthrax and in particular poaching. From 1981 to June 1983, 17 mortalities relating mainly to unnatural causes were recorded, including 7 confirmed cases of poaching. As a consequence, in certain areas, many rhinoceroses have left traditional home ranges and a number of unrecorded mortalities are suspected. Control measures include the sucessful translocation of 29 rhinoceroses to the east of Etosha and in 1981, the vaccination of 36 rhinoceros against anthrax.
With anti-poaching measures presently being inadequate, poaching poses the greatest threat to the black rhinoceros population. The implementation of effective anti-poaching measures has become a matter of urgency and is presently receiving attention.
