Although the opportunistic feeding habits of leopards were evident in this study, scat analysis showed that ungulates were by far the predominant food, with impala being the most frequent item. The fact that cattle calves were only taken up to ± 100 days old, emphasize the relevance of a proper stock management program to prevent stock losses. In addition, where such measures were impractical, temporary physical barriers such as electric fencing showed potential for application. Modification on different capture techniques were investigated not only to capture leopards for radio collaring but also for the elimination of problem leopards. The effective home range size of a resident male and female leopard in the Naboomspruit area were calculated at 303 km2 and 157 km2 respectively. A density of one leopard per 53 km2 are suggested for the Naboosmpruit study area. Both leopards were predominantly nocturnal with some crepuscular activity. Translocation experiments revealed different results. The conducting of translocations in farming areas, where problem leopards are involved are however not suggested. Leopard density and distribution patterns showed that numbers are relative safe, and that populations are currently to a large extent linked, which makes natural gene flow a possibility. Although suitable areas for leopards thus exist, these may not be available as homogenous units in the future, due to increasing human pressure. / Dissertation (MSc (Zoology))--University of Pretoria, 2006. / Zoology and Entomology / unrestricted
