Operation Wallacea and our partners, Wildlife and Ecological Investments (WEI), coordinate large-scale research programmes to provide an empirical backbone for key conservation projects in South Africa. Our main aim is to assist conservation managers with pressing large-scale issues that they do not necessarily have the resources to address themselves. The South Africa research programme covers a series of reserves across the country, each using slightly different management strategies to conserve wildlife in their reserves. Big game areas in South Africa are fenced to avoid the spread of disease and conflicts between communities and dangerous animals. However, in reserves surrounded by densely populated areas such as Somkhanda Game Reserve, human-wildlife conflict can be a major challenge. Here, our research teams are looking at the extent of this conflict with a special focus on large mammal species. Large mammal distributions are monitored regularly through game transects, and nocturnal mammal distributions are assessed using a matrix of camera traps set up throughout the reserve. By combining this information with our knowledge of areas of dense human activity, we can begin to understand how human disturbance can alter large mammal movement and behaviour. 

The restriction of natural movement caused by fences can also lead to locally dense mammal populations with high levels of vegetation impact. Elephants, for example, are ecosystem engineers and their impact can alter vegetation structure and composition. By directly monitoring both fire and feeding impact on vegetation and its knock-on effects to other taxa, such as birds, our teams can assist the reserve managers to better understand how elephants can affect long-term change in the ecosystem. Monitoring of this type is also highly important in Gondwana Game Reserve, which is situated in the biodiversity hotspot of the Cape Floral Kingdom in the Western Cape, and is one of the first reserves to introduce elephants back into this region. This Big-5 reserve has converted agricultural land to conservation, with the large mammals feeding on old agricultural grasslands as fynbos vegetation holds little nutritional value for large herbivores. Reserve management here have therefore asked us to monitor how the large, enigmatic game species are utilising the various vegetation types found within the reserve, to conserve the diversity of critically endangered vegetation types while supporting Big-5 tourism and conservation of the area.
