More and more scientists today are using environmental DNA—or eDNA—to identify species or organisms inhabiting a particular area by measuring genetic traces found in water, soil, or air. In 2019, a group of researchers co-led by WCS’s Tracie Seimon surveyed Mt. Everest to explore high elevation biodiversity there using eDNA. Now that they have begun publishing their findings, WCS Wild Audio checked in with Tracie to find out what they learned.
