South Africa is considering legalising rhino horn trade - in a bid to combat rampant rhino poaching, but the suggestion has been met with mixed reaction in Southern Africa.
Demand for rhino horn is at an all time high and South Africa, which has the largest reserves of the wild animal, is a prime hunting ground for poachers.
Over the past three years, gangs are said to have killed more than 800 rhinos for their horns, which can fetch £22,000 ($35,055) per kg on the black market.
Poachers use a chainsaw to cut away the rhino's horns, after darting it with a tranquilizer - drugged and helpless the animal bleeds to death.
Large syndicates are involved in this multi-billion dollar trade worldwide - exporting the horns from Africa to parts of Asia and the Middle-East.
Despite many anti-poaching measures 310 have been killed in South Africa this year, more than 330 had been killed at the end of last year - and the numbers are set to increase, experts warn.
In the five years up to 2005, an average of 36 rhinos were killed each year.
Some say today's efforts are "too conventional" and are not enough.
Now South Africa has commissioned a study into whether legalising trade in rhino horn could in fact help to bring down poaching, the Department of Environmental Affairs announced recently.
"We are impartial at this stage but we are looking at all the suggestions which could help us in the fight against poachers," the department's spokesperson, Albie Modise, told the BBC.
"We are awaiting submissions and would consider this if we get authentic scientific backing that this would be effective," he said.
The idea is that legalising rhino horn trade would make South Africa directly responsible for meeting the demand for the horns - taking power out of the hands of poachers and placing it in the hands authorities who would also be sensitive to current conservation efforts.
These authorities would do market research into global markets of the trade, said Mr Modise.
The department says rhino horn stock piles could also be sold to fund further rhino conservation efforts.
Mr Modise says the suggestion first came up at a rhino summit held last year to find ways of tackling poaching in southern Africa.
Rhino horn trade is regulated by the Convention on International Trade in Endangered Species (Cites) and at present South Africa allows the export of horns only as hunting trophies.
The legal debate
But the consideration has drawn heavy criticism from international conversation group WWF, which says this would be a setback by decades the efforts made to stabilise the rhino population.
"We understand the need to come up with new ways of combating the rhino horn trade but we are against the notion that legalising it is the answer," said Morne du Plessis, of WWF in South Africa.
