Wildlife authorities in Zimbabwe have begun dehorning the country's 700 adult rhinos to curb rampant poaching, a conservation group said today. "Our target is to dehorn every single adult rhino and to ear-notch the young ones for record-keeping," lisa Marabini, director for the Aware Trust Zimbabwe (ATZ) conservation group, told AFP. "Poaching is a very serious problem in this country. This (dehorning) will act as a dissuasive measure and reduce the potential reward for poachers." ATZ, which includes veterinarians and conservationists, is working with the Zimbabwe Parks and Wildlife Management Authority on the dehorning project. The authority was not immediately available to comment.
