eDNA Assessment

Revolutionising Species Detection

eDNA Assessment

Environmental DNA (eDNA) assessments provide a fast, non-invasive, and highly accurate method for detecting species presence in aquatic and terrestrial environments. By analysing genetic material shed by organisms into their surroundings, we can identify species without the need for physical sightings or trapping, making it an invaluable tool for biodiversity monitoring and environmental compliance.

eDNA is collected from water or soil samples where organisms naturally shed cells, scales, or bodily fluids. These samples are then analysed in a laboratory using advanced DNA sequencing techniques to detect species-specific genetic markers. This process eliminates the need for direct observation, reducing the impact on wildlife and increasing survey efficiency.

The Advantages of eDNA Over Traditional Survey Methods

One of the key benefits of eDNA assessments is the ability to detect species with greater sensitivity than conventional methods. Many species, particularly aquatic or cryptic terrestrial species, can be difficult to locate using visual surveys or trapping techniques. eDNA allows for the detection of rare, endangered, or invasive species with minimal disturbance to the ecosystem.

In addition to enhanced accuracy, eDNA surveys are also faster and more cost-effective. Traditional survey methods often require extensive fieldwork over multiple seasons, while eDNA sampling can be completed quickly and provide reliable results in a fraction of the time. This makes eDNA particularly valuable for large-scale projects or when time-sensitive decisions need to be made.

When Are eDNA Assessments Required?

eDNA assessments are increasingly being used in environmental impact assessments, biodiversity monitoring, and regulatory compliance projects. Developers, councils, and conservationists may require eDNA surveys to confirm species presence in a given area before undertaking construction, habitat restoration, or conservation initiatives. These assessments are particularly useful when traditional survey methods are impractical due to difficult terrain, elusive species, or seasonal activity variations.

For project developers, regulatory agencies, and environmental managers, eDNA surveys offer a powerful tool for ensuring compliance and minimising project delays. The ability to rapidly confirm species presence or absence helps streamline environmental approvals and reduces the risk of costly revisions due to unexpected survey findings.

Furthermore, because eDNA methods are non-invasive, they are ideal for projects where minimal environmental impact is a priority. The reduced need for intensive fieldwork also translates to cost savings, making eDNA a practical and efficient choice for species monitoring and biodiversity assessments.
