Brodie Thomas, a project placement helping to facilitate NatureScot's use of genetic technologies, explains what Environmental DNA is, and how this non-invasive sampling technique can monitor wildlife and help build up a detailed image of what lives where. 

She explains the pros and cons of the technique, how it's being used to detect the presence of invasive non-native species, and the potential use of eDNA to help tackle nature loss and climate change.
