A team of scientists led by the Wildlife Conservation Society (WCS) and Appalachian State University used environmental DNA (eDNA) to document the breadth of high-alpine biodiversity present on Earth's highest mountain, 29,032-foot Mt. Everest (8,849 m). This critical work is part of the 2019 National Geographic and Rolex Perpetual Planet Everest Expedition, the most comprehensive single scientific expedition to the mountain in history.
