Dehorning
In a desperate attempt to stop the killing of rhino from poachers in Zimbabwe, a dehorning policy was introduced by National Parks and Wildlife Management. Unfortunately, this policy has been a failure - over 80 dehorned rhino were killed by poachers in 1993. In addition, dehorning is a very expensive exercise. Due to the growth of the horn stumps, the dehorning has to be repeated on an annual basis and each time there is a risk of mortality from the stress associated with immobilisation and capture.
