Geotagged edna detections by reserve

This data visualization tool allows us to select sample sites at different Reserves and see the eDNA detections from those samples displayed in different ways. These sites are currently in draft form: they do not include all sites, nor all detections, and species ID’s have not been confirmed in all cases.

Great Bay Reserve

Wells Reserve

South Slough Reserve

Hudson River Reserve

nerrs science collaborative 2-page project fact sheet

"Biological monitoring programs are essential foundations for effective management of estuaries and coasts, but they can be expensive to conduct and may be traumatic for the target species. Advancements in DNA methods now make it possible to identify the organisms in an area by the DNA they leave behind. Environmental DNA (eDNA) comes from feces, gametes, scales, and cells that an organism sheds, and is easily collected from water and sediment samples. Rapid reductions in analytical costs now allow scientists to analyze eDNA in water samples and identify..."
