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!

Hey folks! We've just received sequences from our first sampling at the Tremont streams.

Unfortunately, we encountered a few complications while amplifying the DNA (we're working on fixing these for the next batch of samples!), but here's a little teaser from a Pigpen Branch sample collected in June. The chart shows the proportion of sequences that matched each salamander species. It uses scientific names, but here are the common names associated w...
