Bothongo Rhino & Lion Nature Reserve

This guide to the Bothongo Rhino & Lion Nature Reserve begins in 2010, when poachers killed one of the reserve's rhinos for its horn. Owners Ed and Lorinda Hern, working with veterinarian Charles van Niekerk, dreamed up an unusual countermeasure involving dye and a chemical mixed straight into a sedated rhino's horn. You'll hear how the treatment was designed to work at an airport scanner and in a buyer's hands, and why it began in 2011. Listen for what may be grazing nearby, carrying that secret inside its horn.
