![]() ![]() They have a herbivorous diet, small brains (400600 g) for mammals of their size, one or two horns, and a thick (1.55 cm), protective skin formed from layers of collagen positioned in a lattice structure. With respect to the favourable status of the species world-wide, continued introductions were recommended, providing owners were aware of management requirements. Rhinoceroses are some of the largest remaining megafauna: all weigh at least one tonne in adulthood. Habitat utilisation was generally broad, only highly rocky and steep areas being avoided.Ĭertain parts of Namibia’s semi-arid environment were considered to be marginal or inherently unsuitable habitat for white rhino due to overgrazing and low rainfall, but with management support, rhinos can persist and thrive largely independent of the available habitat. Pure patches of grassland and presence of water characterize it during the rainy season. Grazers, on the other hand, favor low-growing vegetation like grass. This habitat type is scattered all over the park area. Browsers tend to favor eating leaves and fruits from bushes and shrubs. They had apparently successfully adapted to utilise this semi-arid environment. All 5 species of rhinoceros are herbivores, only eating plants and other vegetation. In this study, the rhinos were found to primarily select the dominant, soft grass species and areas with high grass density and biomass. Rhino activity locations were overlaid onto spatial maps of environmental parameters and analysed’using GIS techniques. ![]() Following an intensive assessment of the habitat in the area, traditional African tracking techniques were applied to observe and record rhino habitat selection, grazing and activity patterns at approximately 2,000 GPS locations. Spatial utilisation of a group of white rhino in a potentially marginal, semi-arid environment was investigated by comparing rhino habitat selection with that available. White rhino numbers in National Parks have increased due to co-ordinated management and protection operations. Effective management involves protection from poaching, regular monitoring and providing supplementary feed when grazing is poor. ERIC DINERSTEIN, Conservation and Research Center, National Zoological Park. The value of the animals has increased significantly since 1989, which has encouraged farmers to protect and manage rhinos sustainably, and numbers are now increasing. DEMOGRAPHY AND HABITAT USE BY GREATER ONE-HORNED. Most early introductions of white rhinos to private land were not successful due to poaching, over-hunting and poor management. The preferred habitat varies depending on the species, but range from savannas, grassland plains, wetlands, and dense forests in. This study investigated habitat utilisation of the white rhinoceros (Ceratotherium simum simum) in a semi-arid environment and established the history and current status of the species, following its introduction to Namibia.
