Evaluating the accuracy of some commonly used game-counting methods

The accuracy of game counts on an eastern Transvaal Lowveld game ranch was examined. A drive count was used to produce control estimates of actual population sizes. A helicopter count was more accurate than one from a fixed-wing aircraft. Twenty-four hour waterhole counts were relatively inaccurate. Line transect counts were relatively accurate when a fixed […]

Carrying Capacities of Natural Veld in Natal For Large Wild Herbivores

Carrying capacities for wild herbivores in a variety of bioclimatic regions in Natal were examined. In calculating stocking rates, estimated relative energy requirements of the various species were used to equate species of differing size. Herbivores were grouped according to the anatomy of their alimentary canals and to the type and parts of plants they […]

The numerical status of sixteen game species in the Transvaal, excluding the Kruger National Park

The paper describes the results of a survey to determine the numbers of the following game species in the Transvaal: springbok, blesbok, zebra, blue wildebeest, black wildebeest, red hartebeest, gemsbok, eland, nyaia, buffalo, elephant, giraffe and squarelipped rhinoceros. The distribution of each species is discussed and the different localities of occurrence are illustrated. The growing […]

Observations On Lactation And Milk Composition Of The Giraffe Giraffa Camelopardalis

Milk samples collected from giraffe Giraffa camelopardalis in the eastern Transvaal Lowveld of South Africa were analysed by conventional methods. Changes in the composition of the milk at different stages of the lactation cycle were noted. The prelactation secretion and milk of early lactation was considerably richer than the milk of established lactation in terms […]

The behaviour and dietary preferences of southern giraffe (giraffa camelopardalis giraffa) on the umphafa private nature reserve, kwa-zulu natal

The giraffe (Giraffa camelopardalis) has been severely neglected among the scientific community in terms of research. This investigation explores their behavioural patterns with focus on feeding behaviours and dietary preferences under influencing factors, which provides vital information for conservation in situ and population management ex situ. The behaviour and dietary composition of nine Southern Giraffe […]

Genetic Markers in Wild Animal Studies

A survey is given of the work performed in the Onderstepoort laboratory on the studies of genetic markers in wild animals. The implications of using genetic markers reflecting single gene changes in animal studies are discussed. Preliminary results indicate that certain wild animal populations are genetically less variable than others, and the consequences are discussed. […]
