Rhinos in Africa are killed for their valuable horns on a daily basis. Scientists from Wageningen University & Research are currently running tests in which they fit ungulates such as zebras and wildebeests with GPS transmitters. Restlessness and flight behaviour in these ungulates appears to warn for the presence of poachers. In the future, a smart computer system will collect these signals and alert the park rangers. Which technology would you like to use for nature conservation?
