The process begins with the Rhinos Without Borders team working with game managers in South Africa to identify animals in reserves that are crowded or are facing intense poaching threats.
Once the rhino are selected, an experienced vet darts them with a sedative from a helicopter. Then the rhinos are blindfolded and given ear plugs to keep them calm while medical checks are undertaken. Once they are ready to be moved, a rope is placed around their head and they are given an antidote to the sedative, before being walked into a crate. Rhino hide is between 1.5 – 5 cm thick so the dart must be powerful enough to penetrate its armour!
