In response to valid concerns that increasing the demand for rhino horn by wealthy consumers in Asia (which far exceeds any possible supply from dehorning live rhinos), particularly over the last decade, has led to the killing of rhino and the decimation of many African rhino populations, the international trade in rhino horn is banned under the Convention on International Trade in Endangered Species (CITES). Unquestionably, the devastating loss of thousands of rhinos in South Africa particularly over the past two decades is not only due to the illegal killing of rhinos. These unacceptably high numbers of decimation are also the result of: contentious policy and management decisions; direct involvement of some of South Africa’s professional trophy hunters; corrupt members of the South African Police Service; some rhino breeders; crooked veterinarians and nature conservation officials; and South Africa’s porous border. South African wildlife farmers Johan Kruger and John Hume, Wildlife Ranching South Africa (WRSA), and the Private Rhino Owners Association (PROA) pushed to open the domestic trade in rhino horn, arguing it was their constitutional right to sell a so-called "renewable resource." Dawie Groenewald, a South African wildlife farmer, hunting safari operator and an alleged wildlife trafficker who, is also facing more than 1600 charges related to rhino poaching in South Africa, claimed in an interview with Bryan Christy in National Geographic, that he was the mastermind behind this pro-trade legal battle. Groenewald stated that whilst Kruger’s name was on the court papers, he was the one behind the master plan.
