Mpumalanga - Game reserves in Mpumalanga are battling to keep their rhino alive and conservationists are now resorting to putting poison in horns in a desperate attempt to keep poachers away.
The animals are tranquilised and a specialised veterinary team drills into the horn before injecting a pink poison that is said to render them useless in the black market.
Lorinda Hearn, of Rhino Rescue Project said, "The fact that we have to resort to measures like this is a testament to how dire the poaching situation is in the country."
Rhino horns can fetch nearly R10 million in parts of Asia.
Conservationists say the legalisation of rhino horn may be the only option.
Environmentalists predict if poaching continues at its current pace, South Africa's rhino population could soon become extinct.
