Development of integrated wildlife and livestock land uses will maximise returns of economic direct use value (Barnes et al. 2003), enhance biodiversity conservation and alleviate poverty. The pastoral communities in semi-arid and arid rangelands are looking for information and options for increased income from livestock production and marketing including, if possible, some income from wildlife. They expect KARl to help identifying the best model for the wildlife and livestock integration. This includes ways to improve livestock production and management to reduce diseases; to reduce predation problems with new strategies including alternative ways of enclosing livestock at night; to harvest trees sustainably; more up-dated information on government policies and guidance in natural resource management and co-existence of wildlife and people with their livestock. In such pastoral lands, soil fertility and water availability drive the plant species diversity, but moderate levels of grazing can increase the richness of plant species and can stimulate the productivity of grasses. Moderate amounts of grazing by wildlife can double the productivity of grass for the grazer (McNaughton 1976, 1979) and improve the nutrient contents of the grass (McNaughton 1988). Thus when livestock 'populations are low to moderate, they sometimes can diversify plant communities and improve energy and nutrient flows to other grazers
