The diet selection, habitat preferences and spatial ecology of relocated giraffe (Giraffa camelopardalis) in the Kgalagadi Transfrontier Park
Old records and historic eyewitness accounts of giraffe (Giraffa camelopardalis) in the Kalahari, led to the decision by park management to reintroduce giraffe in 1991. Twenty years ago (1991) the translocation of 8 giraffe from the Etosha National Park took place to an area in the Kgalagadi Transfrontier Park which there is limited information as […]
Use of home range behaviour to assess establishment in translocated giraffes
Conservation translocation is a management technique employed to introduce, re-introduce or reinforce wild animal and plant populations. Giraffe translocations are being conducted throughout Africa, but the lack of effective post-translocation monitoring limits our ability to assess translocation outcomes. One potential indicator of translocation success is the establishment of characteristic movement and home range behaviour in […]
Movement patterns and herd dynamics among South African giraffes (Giraffa camelopardalis giraffa)
Giraffes reside in a fission–fusion social system, with sex, age proximity, kinship and home range overlap accounting for some of the variance in herd composition, while season, sex, age and time of day influence diet, home range size and distance travelled. To increase our knowledge of habitat use and fission–fusion herd dynamics, we placed GPS […]
Right on track? Performance of satellite telemetry in terrestrial wildlife research
Satellite telemetry is an increasingly utilized technology in wildlife research, and current devices can track individual animal movements at unprecedented spatial and temporal resolutions. However, as we enter the golden age of satellite telemetry, we need an in-depth understanding of the main technological, species-specific and environmental factors that determine the success and failure of satellite […]
Home range and seasonal movements of Giraffa camelopardalis angolensis in the northern Namib Desert
Estimates of home range size of giraffe in the northern Namib Desert were on average larger than those in other populations. In particular, the largest individual home range of any giraffe bull (1950 km2) was recorded – correlated with low population density, reduced forage density and increased searching for receptive cows. The predominant pattern of […]
Collared!
North-western Namibia is a spectacular land of desert mountains, gorges, plains, and ephemeral rivers, and a land of stark beauty and seemingly inhospitable wilderness. It was here that the wildlife vet and capture expert Michael D. Kock came to help attach satellite collars to desert-dwelling elephants and giraffes so that their movements in their vast […]
