What chance have the rhinos?

The hunters use three kind of trap for rhino, the most harmful to the population being the one that drives spear deep into the rhino's back, because, not only does it very rarely kill the rhino immediately, but local hunters admitted that more than half of the speared rhinos were never found. Dr Borner himself found evidence of one rhino that had tried to rub the spear off its back on surrounding trees and must have run several kilometres before it died of internal injuries.
