This project tests the use of modern metabarcoding techniques to determine presence of amphibian and fish species in mountain lakes in the Oregon Cascade Range. The project collects and preserves environmental DNA from a range of lakes that can be analyzed to provide information on persistence of game fish where they have been stocked and biodiversity of amphibians in alpine and subalpine lakes in the Cascades. We also will use this information along with habitat measurements to understand what habitat conditions facilitate fish and amphibian co-existence.
