Water Voles Return to River Wey Following Two-Decade Hiatus

Water voles have been reintroduced to the River Wey in Farnham, marking a significant milestone after a 20-year absence from the local area. Approximately 300 of these animals were released into the town center’s waterways as part of a broader initiative aimed at restoring the species, which the National Trust identified as Britain’s fastest-declining mammal due to predation and habitat destruction.

The Monday release in Surrey was a collaborative effort led by the National Trust and the Environment Agency, supported by various local organizations and volunteers. The species, famously known as "Ratty" in The Wind in the Willows, had been locally extinct for twenty years, according to David Elliott, the National Trust’s lead ranger for South Downs West.

"This wonderful little animal is making a comeback, and we are thrilled to share this news with the residents of Farnham," Elliott stated. He emphasized the importance of the event, noting, "The water vole was once a common species. While the loss of rare animals often captures public interest, the disappearance of common species is what truly demands our concern."

Conservationists are working to re-establish a self-sustaining water vole population stretching along the River Wey, from its origin on Black Down in the South Downs National Park down to Weybridge on the Thames. Paul Davy, the Environment Agency’s River Wey catchment coordinator, hailed the initiative as a vital project. He described the water vole as a "much-loved native species and ecosystem engineer" that had been missing from the Wey catchment for a considerable time.

Libby Ralph, a Farnham resident and volunteer, recalled seeing water voles during the 1980s. Although she participated in a county-wide survey between 2014 and 2015, she noted that the results were disheartening. "We searched diligently but, sadly, concluded that water voles were functionally extinct in Surrey," she said. "I have hoped ever since that we would one day be able to return them to the River Wey."

This event marks the second release of the species in the region, following an initial introduction near Haslemere last August. Additional releases are scheduled over the next year, with early indicators suggesting that the first groups have successfully established themselves.

According to the National Trust, water voles are crucial for riverside biodiversity. They serve as a food source for predators like otters and barn owls, while their grazing habits help reshape habitats and create opportunities for rare plants to thrive.
