Water Voles

Water Voles are at risk of extinction due mainly to the American Mink.  It is believed that water vole numbers are down by one fifth – including no water voles in Cornwall.   Mink escaped from fur farms into British canals, and are today causing a huge decline in water vole population, as they are a mink’s favourite prey.  It has been stated that if we do not try to control the numbers of mink in our canals and rivers, water voles ‘will become extinct in England.’  With programmes being put in place to control the levels of mink (trapping) the population of voles should increase, although the government will not propose funding due to the mink not being seen as an economic threat, meaning that the funding to help save the voles is provided by charities.  Apart from the mink, the disappearance of water meadows and riverside vegetation - which is what the herbivore water voles live on – has helped in the decline of numbers.

Darren Tansley (small mammal specialist and Essex Wildlife Trust’s Water for Wildlife Officer) and his team have been working exceedingly hard to boost the numbers of vole within Essex.  Darren and the team (mainly volunteers), recently surveyed Essex waterways to count numbers of water voles.  They then caught hundreds of water vole at Fingringhoe Wick Nature Reserve (as their habitat would soon be flooded) and then re-homed them within the Bishop Stortford estuaries where their populations will hopefully flourish.  Reports suggest that the water voles have settled in well at Bishop Stortford.
