“Cutting off the horns of sedated rhinos with a chainsaw has been viewed by wildlife conservationists in Africa for more than 30 years as a necessary evil to save the iconic endangered species from poaching. They hoped the drastic action was working, but evidence was scarce. Now, a study published Thursday in the academic journal Science has found that dehorning rhinos has led to a large reduction in poaching in game reserves in and around the Kruger National Park in northern South Africa — an area that’s home to 25% of the world’s rhinos and is especially vulnerable to poaching. The results of the seven-year study that ended in 2023 are seen as long-awaited evidence that removing rhinos’ horns — which needs to be done every one to two years because they grow back — helps them survive, even if the animals lose part of their makeup.” (06/05/25)
