Testing the Waters: Unlocking River Wandle’s Hidden Biodiversity with eDNA

Who really calls the River Wandle home? In the lead-up to the UK River Summit, we’re excited to announce a collaboration with Trace Biomonitoring to reveal the hidden wildlife of the river using cutting-edge environmental DNA (eDNA) technology. 

What is eDNA and Why Does it Matter? 

All living creatures constantly shed DNA into their surroundings—whether through skin cells, scales, waste, or other biological material. By collecting water samples and filtering out this environmental DNA, scientists can identify the diverse species present in a given ecosystem without disturbing them. This method offers a powerful, non-invasive way to monitor biodiversity and track changes in freshwater health. 

eDNA Sampling on the Wandle 

Trace Biomonitoring will take five eDNA samples from different points along the length of the River Wandle. The data will reveal which species are thriving in the river, helping us build a clearer picture of its ecological health. Ahead of the Summit, we’ll share these findings to spark conversation and raise awareness about the incredible life supported by this urban river. 

Showcasing the Results at the UK River Summit 

At the Summit, we’ll display key insights from this eDNA study, and a specialist from Trace Biomonitoring will be on hand to discuss how molecular tools like eDNA are revolutionizing the way we monitor and protect our waterways. This collaboration highlights the power of innovative science in conservation and how new techniques can make river monitoring more accessible and impactful. 

Stay tuned as we uncover the hidden biodiversity of the River Wandle!
