Whodunit? Using DNA to Identify Predators

Wolves, bears, mountain lions, and coyotes can sometimes attack and kill livestock. Many USDA Wildlife Services (WS) field specialists are experts in determining which predator species is responsible for livestock depredation events based on the location of the injuries, tooth marks, tracks, and other clues. But sometimes the clues left at the scene are not enough and more high-tech methods are needed. WS is exploring how predator DNA collected at predation sites can help improve our understanding of predator-prey interactions and the impacts of predators on livestock and endangered species.
