How is eDNA used?
Used in various fields including conservation biology, ecology, and wider environmental monitoring in both terrestrial and aquatic environments, eDNA sampling can be used to assess species richness, track changes in biodiversity, monitor invasive species, and for comparing the effectiveness of different nature restoration efforts.
When it comes to assessing species in remote or landscape-size locations, eDNA sampling can be more time-efficient and cost-effective than traditional survey methods as multiple samples can be gathered at the same time, reducing the need for time-consuming fieldwork.
eDNA data provides insight into quality and suitability of habitats based on the identified presence of indicator species (species which when present, represent the wider health status of an ecosystem). Methodologies and techniques used to collect eDNA data can be standardised, making it easier to quantify and compare results across different habitats and regions and enhancing collaboration and data sharing among researchers and land managers.
