The Rietvlei Nature Reserve, situated between Johannesburg and Pretoria, has introduced a new male cheetah into its 3 800ha reserve after a two year absence in order to regulate the prey population in the reserve. The reserve was left without cheetah after the two male cheetah, which got reintroduced into Rietvlei in March 2003, died in 2012 and 2013 from old age. Rietvlei Game Reserve and the Endangered Wildlife Trust (EWT) are currently also searching for a female cheetah to join the new male. This should happen by early 2015. Rietvlei Nature Reserve forms part of EWT's Cheetah Metapopulation Project.
