Discover ABMI Data & tools
While audio recorders are used to monitor calling frogs and toads, salamanders cannot be detected using this method. Therefore, we conducted a pilot project with Innotech Alberta to explore the effectiveness of environmental DNA (eDNA) technology for monitoring amphibians—including salamanders—in wetland habitats. The objectives of the project were to:
The project revealed that eDNA is a valuable tool in the monitoring tool box. Results indicated that both monitoring methods (eDNA and ARUs) had advantages depending on the target species. For example, non-calling Tiger Salamanders were only detected by the eDNA method while ARUs detected a single western toad at one site that was not detected by eDNA. We are continuing to work with Innotech to improve eDNA sampling methodologies for amphibians and are exploring DNA monitoring methods for macroinvertebrates and vascular plants.
