The spatial ecology, habitat preference and diet selection of giraffe (Giraffa Camelopardalis Giraffa) in the Kalahari region of South Africa

The research project was conducted within two separate study areas. The main research project was conducted in the Khamab Kalahari Nature Reserve (KKNR) in the North West Province of South Africa. The main research project only commenced after the completion of a preliminary study that was conducted on the Woodland Hills Wildlife Estate in the Free State Province of South Africa.Little is known of the environmental impacts on giraffe in this ecological region, and concern has been expressed regarding population

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 strip width equal to the mean visibility index of the vegetation was used, and when the population estimate was based on the perpendicular sighting distance.

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 concern for the conservation of wildlife in the Transvaal has resulted in an increase in the numbers of most of the species during the past

The implications of the reclassification of South African wildlife species as farm animals

The Government Gazette No. 42464 dated 17 May 20191 amended Table 7 of the Animal Improvement Act (Act no. 62 of 1998), which lists breeds of animals, to include at least 32 new wild animal species, including 24 indigenous mammals. The list includes threatened and rare species such as cheetah, white and black rhinoceros, and suni. Some alien species such as lechwe, various deer species and rabbits are also included. The cornerstone of the original Act is ‘To provide for

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 of total solids, fat, ash, and protein but not in lactose. Differences in minerals and trace elements were not significant. Giraffe milk is richer than

Estimating the trends in herbivore numbers in the Southern District of the Kruger National Park

Census data over several years of survey were utilized to develop a sampling strategy in which the species totals for both abundant and rare herbivore species can be estimated should aerial sample surveys be conducted. Correspondence analysis is used towards the development of this sampling strategy. The study pertains to the Southern District of the Kruger National Park. Census data from 1977 to 1989 were used. It is shown that the trends indicated by the census data, are also clearly

Diet and seasonal dispersal of extralimital giraffe at Sanbona Wildlife Reserve, Little Karoo, South Africa

South African giraffe (Giraffa camelopardalis giraffa) have been introduced as an extralimital species to private farms in the Little Karoo on the basis of economic sustainability, and the need to create a competitive tourism product. However, little is known about the medium- to long-term impacts and ecological sustainability of such introductions. The diet of a population of giraffe on Sanbona Wildlife Reserve, near the town of Ladismith, was assessed via direct observations between January and October 2014, in order to

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. If this phenomenon should be substantiated by further investigations, then certain corrective measures to ensure the survival of certain animal groups or even species would

Habitat partitioning by ungulates on a game ranch in the Mopani veld

Large herbivores display varying degrees of habitat selectivity and thus exhibit a heterogeneous distribution. This study investigated the spatial and temporal distribution of Burchells zebra Equus burchelli, blue wildebeest Connochaetes taurinus, eland Taurotragus oryx, gemsbok Oryx gazella, giraffe Giraffa camelopardalis, impala Aepyceros melampus, kudu Tragelaphus strepsiceros, and warthog Phacochoerus aethiopicus, on the Messina Experimental Farm. The sighting frequency of the ungulates, expressed as distance covered by vehicle, divided by the number of individuals of a species recorded, is presented for

Two quantitative methods of analysing ungulate habitat data

Ungulate habitat data for 10 ungulate types that use the grasslands of Jack Scott Nature Reserve were quantitatively analysed using simultaneous confidence intervals and detrended correspondence analysis. The first method is hypothesis-testing whereas the second method is hypothesis-generating. The two methods complemented each other and both revealed the same major habitat selection patterns.
