Conservationists fear that poaching may escalate as a result of the decision by the department of energy affairs and tourism to cut down on rhino hunting. One response to the illicit rhino horn trade is the micro-chip project, which will see samples taken from horns of dead rhino stored in registered containers and kept safe for future use in DNA finger printing.
