Using environmental DNA (eDNA) analysis, scientists revealed evidence for extensive species diversity in streams, some of which was previously hidden. They also detected salmonids (migratory fish species such as Pacific salmon and cutthroat trout) further upstream than expected, which has significant implications for conservation and forest management.
