Abstract

Selected Papers from the Rhinoceros Conservation Workshop, Skukuza, Kruger National Park,31 August – 4 September 1988 Water-hole census techniques as developed in Etosha for monitoring black rhinoceros are described in detail. The systematic recording of animals visiting water-holes at night yielded data on the population size and structure, and frequency of drinking of this species. Population size estimates derived from this method were compared with estimates derived from aerial census techniques. It was concluded that censusing at a water-hole accounted for 32 percent more animals than a total aerial count by helicopter, and 70 percent more animals than by using a fixed- wing aircraft.
