Date Time Zebras with high-tech sensors detect rhino poachers Scientists at Wageningen University & Research have developed a high-tech early warning system for poaching. By equipping prey animals such as zebras, wildebeests and antelopes with sensors, suspicious changes in their movements are detected. Algorithms then recognise whether this behaviour may have been caused by poachers. This technology could represent a breakthrough in the fight against poaching. Poaching puts pressure on populations of targeted species, including rhinos and elephants, around the world. “It’s an enormously lucrative industry that’s difficult to stop,” says ecologist Henjo de Knegt. “In this study, we are using the latest technologies to help reduce poaching.”
