In African reserves where the practice of dehorning animals has been implemented, poaching rates have seen a dramatic decrease of over fifty per cent. This method focuses on the removal of rhinoceros’ horns, which are highly coveted in certain regions of Asia. Like the human process of cutting nails, the dehorned rhinoceros near Kruger National Park in South Africa will eventually witness the regrowth of its horns.
In the battle against poaching in Africa, the strategy that wildlife managers tend to adopt is akin to taking a sledgehammer to crack a nut. This involves investing heavily in reinforced ranger patrols, the latest surveillance hardware, scent detection canines, and even the use of helicopters. These measures are primarily employed to safeguard rhinos, the horns of which continue to garner interest in places like China and Vietnam.
Despite the extensive resources allocated towards rhino preservation efforts, one of the most effective methods to prevent their slaughter is comparably simple and cost-effective: dehorning. This is according to research findings published in the scientific journal, Science, with statistics revealing a significant 78 per cent decrease in rhino poaching across eight reserves in Southern Africa due to dehorning initiatives.
In contrast, conventional law enforcement techniques seem to have less impact. Regardless of numerous arrests of alleged poachers, the study demonstrated that such aggressive law enforcement tactics did not drastically reduce the number of rhino casualties. The dominant approach to combating wildlife crime for several decades has been to apprehend and prosecute poachers. However, the outcome of this investigation indicates that it is time to critically reassess the sustainability and effectiveness of this approach.
One of the major contributions of the study is tackling the desperate need for substantial data to support the dehorning practice. While it’s a commonly employed tactic, it has faced significant criticism questioning both its real impact and associated costs. Yet, the results of this investigation indicate that the advantages of dehorning considerably outweigh the fiscal and logistical burdens.
The trend of rhino dehorning found a strong footing in Southern Africa when the poaching menace surged about a decade ago. Assumed to be a pain-free process, dehorning necessitates the tranquilization of the rhinos before sawing the upper parts of their horns, taking care to stay above the nerves.
Functionally similar to the human practice of trimming fingernails, the removed horns will eventually regenerate. In the context of rhinos, the horns usually replenish themselves in an estimated time frame of 18 months. It’s clear that such a non-invasive procedure, when executed with care and precision, has strong potential to contribute significantly towards the preservation of a species under threat.
