Streams harbor many secretive and rare species that are difficult to find and study. Under the Amphibian Research and Monitoring Initiative, USGS scientists and their partners developed and demonstrated an efficient protocol for detecting the DNA of stream-dwelling amphibians that occur in low density in fast-moving water. The simple protocol is widely applicable to inventory and monitoring efforts across large watersheds, and could revolutionize surveys for various stream-dwelling amphibians the way that sampling fur for the DNA has for elusive mammals.
