The American mink — a non-native predator introduced to the UK through fur farming in the 20th century — has been a major factor in the 94% decline of native water voles. Since 2023, River Thame Conservation Trust have partnered with the Berkshire, Buckinghamshire and Oxfordshire Wildlife Trust (BBOWT) to deliver a landscape-scale American mink control programme across the Thame catchment.
Thanks to this work, although the River Thame had not seen confirmed, sustained water vole presence since the early 2000s, there were some sightings in late 2025.
Unfortunately the initial funding that supported this work has now come to an end, and despite efforts, further funding has not yet been secured. RTCT is currently exploring alternative ways to maintain and build on this momentum, including support for the volunteer network, equipment and monitoring.
If you would like to help support this vital work to continue there are many ways you can get involved - through volunteering, donations or by attending the Shabbington Ball in September this year.
This Bond-inspired evening takes place on Saturday 19th September in a glamorous marquee in Shabbington, with tickets now on general sale. Guests can expect a sparkling reception, gala dinner, live music and more all in support of two local charities - with RTCT being one. But hurry - there are only a few tickets left.
