Environmental DNA (eDNA) is organismal DNA that can be found in the environment. eDNA originates from cellular material shed by organisms (e.g., skin, hair, saliva, or feces) into aquatic and terrestrial environments. Researchers sample the air, soil, water or other areas to track or detect invasive, endangered, or rare species.
Use of eDNA for Inventory and Monitoring
Improved Detection of Native Species
Protocols using eDNA allows for cost-effective and standardized detection tool of species distribution, especially species that can be difficult to find and identify.
Early Detection of Invasive Species
Environmental DNA can be an effective tool for early detection of invasive species (e.g., Invasive Carp, dreissenid mussels, etc.). Random or regular sampling can help detect and track the presence of invasive species by taking samples in natural ecosystems or at ports of entry (e.g., airports or shipping containers).
