Invisible Trace Evidence: Using Environmental DNA (eDNA) to Detect Species in Aquatic Ecosystems
Highly accurate – eDNA sampling when correctly implemented, is definitive for detection of presence and very sensitive to detection of aquatic species; The credibility of eDNA survey data, however, depends on adequate methodological validation and verification; accurate results require rigour during field sampling, sample processing, laboratory analysis, and primer design and/or verification. Hemmera recently developed accepted standards for collection of eDNA for the BC Ministry of Environment and has completed for multiple transportation projects including MOTI’s South Fraser Perimeter Road (target species - red-legged frog and Pacific water shrew), MOTI’s Kicking Horse Canyon Phase 4 (target species Western toad) and TransLink’s Surrey Langley SkyTrain project (target species – multiple salmonids, Pacific water shrew and red-legged frog).
