Camera-trap evidence that the silver-backed chevrotain Tragulus versicolor remains in the wild in Vietnam

In an age of mass extinctions, confirming the survival of lost species provides rare second chances for biodiversity conservation. The silver-backed chevrotain Tragulus versicolor , a diminutive species of ungulate known only from Vietnam, has been lost to science for almost three decades. Here, we provide evidence that the silver-backed chevrotain still exists and the first photographs of the species in the wild, and urge immediate conservation actions to ensure its survival. Interviews with local people and camera-trap surveys have led to the first scientifically confirmed sightings of the silver-backed chevrotain for more than 25 years. The news that this species is not extinct is tempered by major threats of habitat loss and poaching in the region.
