About eDNA?

Environmental DNA (eDNA for short) is DNA that’s released into the water by plants and animals in a host of ways: from their skin, faeces, mucous, hair, eggs and sperm, or when they die. It is now possible to monitor the freshwater species that live in ponds, streams and other waterbodies simply by collecting a water sample, and analysing it for traces of DNA.

Freshwater Habitats Trust was involved in the first large scale application of this exciting new technique – investigating its potential to survey ponds for Great Crested Newts across England and Wales in 2013.  With the help of many wonderful volunteers we’ve now gone on to collect the first national data set as part of PondNet 2015. The method is also being used to identify sites with alien American Bullfrogs.
