Though large scale protected areas have become a crucial concept in conservation, the implementation of such projects are often constrained by cost. It becomes crucial, then, for parks to develop a cost-effective method of sampling which can serve the dual purpose of both monitoring and planning conservation areas. By using CyberTracker data collected in Kruger National Park, Hui et al. have compared various models of sampling in order to determine the most accurate and least effort intensive mode of gathering data.
