eDNA has many benefits and is a method that not only provides specific species detection but can also be used to conduct biodiversity assessments and perform dietary analyses.
A single sample can be used to test for multiple un-related taxonomic groups e.g., fish, invertebrates, mammals, and some pathogens.
The many benefits of eDNA testing include:
- Sensitivity with detection of species at low densities
- eDNA surveys are less invasive and provide a lower risk of transferring INNS and/or disturbing protected species than traditional survey methods
- Sample collection is quick and generally requires fewer resources than traditional methods, therefore often saving money
eDNA is particularly good for sites of public interest or for confidential projects as it is less obvious and can be completed quickly. For example, electric fishing surveys require several team members and can attract a lot of attention from passers-by.
