eDNA

eDNA

eDNA is a rapidly advancing field that is allowing for early detection of aquatic invasive and at-risk species. The AEPA and the Hanington lab are at the forefront of helping advance this work in Alberta.

Communities and organizations are 'diving in' to help with the boots on the ground aspect of the work, which can be done by anyone who's received training. This "citizen science" approach allows the scientists with expertise to focus on the in-lab analysis.

NSWA first worked with AEPA and the Hanington lab in the summer of 2023 and just completed more extensive sampling in the summer of 2024. Two Summer Field Research Technicians were hired to undertake the eDNA water sampling and to broaden connections and partnerships with Indigenous communities. 

2024 eDNA Sampling Sites in the NSR Watershed

NSWA Field Research Technicians completed 108 eDNA samples across the watershed's four reaches during the summer of 2024. This map outlines the sites visited, some of which were sampled multiple times.

Preliminary results show that no new invasive species have been detected in the watershed. Whirling disease, first found in the watershed’s headwaters in 2018, has not
shown signs of expanding its range.

The NSWA is continuing periodic eDNA sampling throughout 2025. Together, the NSWA and partners can ensure early detection of invasive species and the coordination of a quick response.
