PRETORIA - A South African judge on Thursday lifted a domestic ban on trade in rhino horns, alarming conservationists who described it as an “extremely dangerous move” that could worsen a poaching crisis. The government said it planned to appeal against the ruling, which was delivered in the Pretoria High Court after two South African game breeders fought a legal battle to overturn the moratorium. The court decision came ahead of a meeting in Johannesburg next year of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), which could lift the global ban. South Africa’s rhino poaching epidemic saw a record 1,215 rhino killed last year for their horn, and some private rhino breeders say selling legally-harvested horns could stifle the lucrative black market trade. Rhinos are slaughtered by poachers for their horn, which is used as a traditional medicine in east Asia.
