First Water Vole release in Surrey for over 20 years in Upper Hogsmill River!

On 30 July, we joined our partners, South East Rivers Trust and Citizen Zoo, to release the first water voles in Surrey for over 20 years.  Around 50 water voles were released onto the Hogsmill river and Chamber Meads wetland at a celebratory event. 

The return of this endangered species marks a major milestone for Surrey’s biodiversity and one of the most exciting rewilding projects in the region. The project also underpins our commitment to manage biodiversity and create resilient ecosystems across the borough that support climate change.

This milestone was the result of a pioneering wetland restoration project led by the South East Rivers Trust (SERT) and reintroduction project by rewilding organisation Citizen Zoo, with support from Wildwood Trust, Natural England Species Recovery Programme, Thames Water and Epsom & Ewell Borough Council.  

The Wildwood Trust, based in Kent and Devon, is one of the UK’s leading centres for conservation breeding, and bred 50 water voles through its expert captive breeding programme for release on the upper Hogsmill river. Wildwood has played a key role in restoring water vole populations across the UK.  

“We are deeply committed to protecting and nurturing habitats that help biodiversity flourish, and we are honoured that the Upper Hogsmill River in our borough has been chosen as the second release site for the reintroduction of water voles.” said Councillor Liz Frost, Chair of Epsom & Ewell Borough Council’s Environment Committee. “They will be the first water voles living in the wild in Surrey for over 20 years. This milestone reflects the strength of our partnerships to create the right conditions for these once-extinct animals to thrive and reflects our borough’s dedication to managing biodiversity and creating resilient ecosystems that play a role in tackling climate change.” 

“Water voles were once a familiar sight on the Hogsmill, but due to habitat loss and invasive predators, they died out.  Now, after years of dedicated river restoration work, and the creation of the flagship wetland at Chamber Mead, as well as extensive monitoring by a band of dedicated local volunteers , we’re thrilled to have brought them back to the upper Hogsmill in Surrey,” said Dr Bella Davies, CEO of the South East Rivers Trust.  

“This is not just a win for water voles—it's a flagship moment for urban river restoration across the UK,” said Elliot Newton,  Director of Rewilding at Citizen Zoo. “With the help of local people, we’re giving this species a real chance to thrive again.”  

 “The UK’s biodiversity is facing a critical decline - putting our ecosystems, food security, and climate resilience at risk,” said Tyrone Capel, Conservation Officer at Wildwood Trust. “Ambitious rewilding projects like this are central to our mission: returning nature to the places it once thrived. We’re proud to support this initiative by breeding water voles for release along the Hogsmill and ultimately reversing the near 20 year extinction of Water voles in Surrey.”
