2nd Water Vole Release in The Lost Valley
This week marks a special milestone in our conservation journey at Heligan, as we continue to restore one of Britain’s most endearing and threatened mammals to our landscape. Following on from last September’s successful water vole release, we have now completed the next stage of the project with a second release into The Lost Valley.
A Species in Need of Protection
Water voles, often remembered as the inspiration for Ratty in The Wind in the Willows, are Britain’s fastest-declining mammal. Once widespread across our rivers, ditches, and wetlands, they have suffered catastrophic losses over the last century due to habitat loss, pollution, and predation by invasive American mink. Conservation efforts like ours play a vital role in reversing that decline, reconnecting this much-loved species with the environments they need to survive.
By restoring water voles to our river catchment, we not only safeguard their future but also improve the health of our wetland ecosystems. These small mammals are ecological engineers, their burrowing and grazing helping to shape riverbanks and encourage diverse plant growth that benefits countless other species.
From the Beaver Enclosure to the Sea
Our first release last year was a resounding success. Since then, the voles have spread through our river catchment, journeying from the beaver enclosure all the way down towards Mevagissey. Habitat surveys carried out by our team have shown just how well they are adapting. Along the banks of our large lakes in The Lost Valley, we have found numerous burrows and tunnels, a clear sign of flourishing activity. Most excitingly, we have even photographed them with their young, known as pups, proof that this population is breeding and establishing itself naturally.
Building on Success
Working again with Derek Gow Consultancy, we have now carried out a second release of water voles into The Lost Valley and further afield across the Heligan estate. These areas were carefully chosen after detailed habitat surveys identified them as suitable environments to support thriving vole populations.Heligan’s Wildlife Coordinator Toby shared his thoughts on the project:
“After the success of our first release, this second batch will help to bolster up our overall population and further increase the chances of this special species thriving here at Heligan for years to come.”
Looking Ahead
The return of water voles to The Lost Valley is more than just a conservation story. It is a sign of resilience, of landscapes healing and species returning where once they had vanished. As the voles settle further into their new homes, we look forward to following their progress and sharing more glimpses of their secretive lives with you.
