Environmentalists in Namibia have accused local wildlife officials of hiding the real extent of rhino poaching in the Etosha National Park, which holds the highest concentration of black rhinos in the world. The Ministry of Environment recently acknowledged that rhino killings at the park quadrupled during the first quarter of 2024. Namibian police apprehended two suspects Sunday for the killing of an adult female black rhino and a medium-sized male calf black rhino at the park's waterhole earlier that day. The two were found in possession of four rhino horns with an estimated value of $55,000. The park has seen a steep increase in rhino poaching, with 28 rhinos killed during the first three months of the year, compared to seven in 2023. Environmental activist and journalist John Grobler attributed the increase, in part, to a three-week mourning period for the passing of Namibia's president, which led to a security lapse by law-enforcement officials. But Grobler suspects officials are still not disclosing the full extent of the rhino poaching. "They still refuse to show us the rhino horn stockpile to show if everything is there, if all the ivory is there," he said. "When you ask them things like this, they tend to sit on their hands for as long as they can before they make any kind of disclosure. My fear is that it could actually be worse than 28 rhinos, it could be more than that."
