Using Environmental DNA and Citizen Science to Monitor Salamanders in Great Smoky Mountains National Park


This is a page for real-time updates about our citizen science projects in Great Smoky Mountains National Park. The goals of these projects are to evaluate the potential of environmental DNA surveys for 1) characterizing plethodontid salamander communities along an elevational gradient; and 2) detecting variation in life history phenology in plethodontid salamanders.


Citizen scientists, check back often for new results!

Hello Citizen Scientists! We finally have sequence data back from our Pigpen Branch eDNA sampling over the last year. We've processed the DNA sequences and compared them to known sequences of salamanders from the Southern Appalachians. Here's a sneak peek at what the data look like. 

Each column represents a separate sequencing reaction from a single sample, and each color represents DNA from a different species of salamander. It's a pretty fi...
