Environmental DNA (eDNA) Brings Accuracy and Confidence to Environmental Surveys

When planning construction, infrastructure projects, or activities such as mining, reliable information about an area’s natural values is essential. Environmental impact assessments (EIA) and various permitting processes require comprehensive ecological surveys to ensure that the effects on nature are properly considered in decision-making.

Traditional methods such as field observations and species identification remain important, but they are often time-consuming and may be affected by human error or weather conditions. eDNA offers a valuable complement to these traditional surveys.

How Does eDNA Work in Practice?

Environmental DNA refers to traces of genetic material left behind by organisms in their surroundings for example, in water, soil, or sediment. When these samples are analyzed in a laboratory, it’s possible to identify which species are present in the area without needing to observe them directly.

This makes species mapping faster, more accurate, and often more cost-effective. eDNA is particularly well-suited for situations where:

• the goal is to detect endangered or rare species, such as the moor frog, freshwater pearl mussel, or various insect species

• a wide range of species needs to be surveyed efficiently at once

• the ecological status of water bodies or soil is being assessed

• repeatable and comparable results are needed for long-term monitoring

Tangible Benefits in Permitting Processes

Using environmental DNA brings clear added value to environmental impact assessments and the various stages of permitting. It can:

• reduce the need for fieldwork and speed up the delivery of results

• improve reliability, as findings are not influenced by human interpretation or weather conditions

• produce data that can be archived and revisited later

• standardize methods, making it easier for authorities to compare results and make informed decisions

eDNA together wtih traditional methods form a stronger foundation for sustainable planning and decision-making.
