Black and white rhino populations in the Greater Kruger (Kruger National Park and surrounding reserves) in South Africa have plummeted from over 10,000 rhinos in 2010 to around 2,600 in 2023. Hundreds of rhinos are killed each year by poachers for their horns. These are sold on the illegal global market.
Nature reserve managers, rangers, international funders, and local non-profit organisations have invested millions of dollars in anti-poaching interventions. These include tracking dogs to track poachers, artificial intelligence-enabled detection cameras, helicopters to monitor reserves and, more recently, dehorning (removing rhinos’ horns reduces the incentive for poachers).
To see if these were working, the Greater Kruger Environmental Protection Foundation set up a research project involving several reserve managers, rangers, and scientists from the University of Cape Town, Nelson Mandela University, University of Stellenbosch, and the University of Oxford.
