eDNA is DNA that is collected from the environment where the individual resides instead of from the organism itself. The eDNA is DNA that has been released from the organism through substances such as mucus, fecal matter, skin cells, carcasses, etc., into the environment it lives in.

eDNA can be used to detect the species of organisms that are currently living in an environment, such as a pond.

"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"

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, please click here for the survey results! The method is also being used to identify sites with alien American Bullfrogs.

The2013 work on the Great Crested Newt was funded by Defra, Natural England, the Joint Nature Conservation Committee and Scottish Natural Heritage, and undertaken by Freshwater Habitats Trust with French genetics specialists SPYGEN, Amphibian and Reptile Conservation and the Durrell Institute of Conservation and Ecology at the University of Kent.
