Mink reported in Colchester - September 2017

Despite efforts to remove mink from the River Colne over the past 8 years, they still appear occasionally and cause problems for the reintroduced water vole population. After 7 years of successful breeding, water voles started to disappear from Cymbeline Meadows this summer and the volunteer River Wardens with Essex Wildlife Trust, co-ordinated by CNHS Mammal Recorder Darren Tansley, set to work removing the mink.

However one has made it’s way into the Lexden area and has been raiding fish ponds in people’s back gardens in the Straight Road area. If you see a dark, ferret like animal in your garden then please email Darren via Essex Wildlife Trust
