Stephen Ornes highlighted many aspects of the impacts and control of wild pigs (2 April, p 40). But there are probably not “23 million feral pigs in Australia”. The paper “How many are there? The use and misuse of continental-scale wildlife abundance estimates” in Wildlife Research reports with 95 per cent confidence that the number is between 3.5 million and 23.5 million, around an estimate of 13.5 million (doi.org/bgr3).
