The re-introduction of large carnivores into relatively small conservation areas that fall within the historic distribution range of the species is becoming an increasingly common occurrence. The success of such re-introductions depends very much on the quality of the information that is available to guide management decisions, but in many cases, little information is available. The re-introduction of lions and cheetahs to Sanbona created the opportunity to monitor the behaviour of re-introduced predators to a relatively large system that was characterised by a low ungulate stocking density and little standing water. The broad aims were to study the feeding and spatial ecologies of the lions and cheetahs, to collect standard base-line data, and to examine the effects of the low prey density and limited standing water on habitat selection, range size and diet. The diet (data collected from direct observation and faecal analysis) was similar to that reported in previous studies, and lions and cheetahs preferred greater kudu, black wildebeest and springbok. Lions preferred medium to large prey items, and cheetahs preferred medium to small prey items. The hilly and mountainous terrain of much of the reserve meant that only 50% of the total space was available to the predators. Home ranges of most of the predators were focused around the single large body of standing water. This is likely to have been a response to the water, the vegetation, and the prey that was attracted to these. Habitat selection was also influenced by inter and intra-specific interactions at least for a solitary male lion and female cheetahs. Range sizes were larger than on some other reserves and it is suggested that this was a result of the low prey density. These results form the basis for management recommendations including the importance of continuing to monitor the system and opening up additional parts of the reserve to the predators.

South Africa presently experiences high levels of crime daily. Although crime is accepted as an everyday occurrence for its citizens, it affects the economy of the country. This study analysed security measures implemented on Commercial Private Game Reserves (CPGRs) in Limpopo and the impact of crime thereof. CPGRs are enclosed areas containing various species of fauna and flora. Visitors from domestic and foreign origins visit these reserves to enjoy nature and its tranquillity. This study analysed the security measures to determine their effectiveness for CPGRs. The study further explored the use of security risk management strategies and risk assessments as crime reduction tools. The study was carried out using a case study research design. Data were collected by the researcher using three methods: observation, onsite checklists and semi-structured one-on-one interviews which were conducted on site. Validity and reliability indicate the trustworthiness of the study. The researcher reduced the data gathered through the use of thematic data analysis. Interviews were transcribed and themes were created and identified by the researcher. The comprehensive data indicated the importance of a security risk manager on a CPGR. The research found that very few security risk managers are employed and that managers of security risks employed on CPGRs have various titles. However, while the CPGRs have similar risks, their risk reduction strategies vary. The most commonly used measures are people, physical and technological measures with each having various subdivisions. The security measures implemented by CPGRs in the Limpopo province which were analysed are not formulated using a scientific approach as most properties do not make use of a formal security risk assessment. The study is deemed valuable as a model was developed from the findings that could be used by game reserves to guide them to apply relevant security measures. A formal security programme is often limited due to financial constraints of the reserve or the reserve owners, however, not all strategies should be considered as a financial expense as much can be done without exhausting financial reserves. The findings contributed to making recommendations to improve the overall security of CPGRs. This study encourages more research into the subject to improve the security industry and to stimulate the tourism industry. / Security Risk Management / M. Tech. (Security Management)

Shamwari Game Reserve was the first enclosed conservation area in the Eastern Cape Province of South Africa to reintroduce free ranging lions, cheetahs, leopards and wild dogs back into their historic range. At that time (2000 – 2001), little information was available on the ecology and behaviour of these predators in the habitats of the Eastern Cape, and management decisions were based on assumptions and unfounded comparisons with extant populations but from quite different habitats. The aim of this study was therefore to obtain a better understanding of the feeding ecology and space use of the predator guild, and the carrying capacity of Shamwari Game Reserve to enable more informed management decisions. In addition, the reserve is a photographic based tourism venture and understanding both the ecological and financial sustainability of the predator guild was important. The diets of the predators were similar to those reported in other studies; larger predators killed a greater range of prey species than did smaller predators and a small number of prey species made up the majority of the kills. The larger predators had a higher mean kill mass than the smaller species and prey selection was influenced by prey size, prey abundance and prey habitat preference, and risk associated with hunting the species. Diet was flexible and responded to natural and management induced changes in prey abundance. There was a considerable overlap in space use by the lions, cheetahs and leopards with their core areas being centred on and around the Bushmans River. Space use was driven by resource distribution and landscape attributes, and by the presence of other predators of the same or different species. The long term viability of wild dog within the reserve was explored and the results confirmed that there was neither the required space nor the ecological processes and the wild dogs were removed from the reserve. A carrying capacity of the reserve for the predator guild was determined using the Maximum Sustainable Yield method to assess the potential prey species off take and a resultant density of 3.3 to 6.6 lion female equivalent units per 10 000 ha was established. The natural carrying capacity of the reserve with respect to predators will not sustain the tourism objectives and consequently prey supplementation was necessary to maintain predator density at levels high enough to sustain tourism. Under these conditions the large predator guild is still sustainable financially although careful, responsible management is needed to provide ecological sustainability.
