Abstract

Species with large geographic ranges are considered resilient to global decline. However, human pressures on biodiversity affect increasingly large areas, in particular across Asia, where market forces drive overexploitation of species. Range-wide threat assessments are often costly and thus extrapolated from non-representative local studies. The Chinese giant salamander (Andrias davidianus), the world’s largest amphibian, is thought to occur across much of China, but populations are harvested for farming as luxury food. Between 2013 and 2016, we conducted field surveys and 2,872 interviews in possibly the largest wildlife survey conducted in China. This extensive effort revealed that populations of this once-widespread species are now critically depleted or extirpated across all surveyed areas of their range, and illegal poaching is widespread.
