Detection of amphibians using environmental DNA

Environmental DNA (eDNA), is a technique that makes it possible to detect organisms by analyzing environmental samples. By examining water samples, we can use eDNA technology to identify and monitor all amphibian species found in Sweden. This provides a simpler and more cost-effective way to track and protect our amphibians.

In spring, amphibians migrate to suitable water bodies for mating and egg-laying. During this period (March–June), they are most active in the water, making it the ideal time for detection using eDNA methods. eDNA sampling offers a fast, cost-efficient, and non-invasive alternative to traditional surveys, and does not require expert knowledge.

IVL offers a simple and practical eDNA sampling kit for water, which includes everything needed to quickly and efficiently filter and preserve samples directly in the field. The sample is then sent to IVL’s eDNA laboratory for analysis.
