I think the voling season may be over: it's true that last year I managed to keep spotting them at White Lion Meadow car park till the start of November, but there was a much bigger colony and also the weather was quite a lot milder. Water voles don't hibernate, but they do spend longer and longer periods underground as winter takes hold.
So instead of a vole I post pictures of the installation of the information board near Whitchurch Country Park. I saw a water vole just across the road from here, swimming under the bridge, one evening early this summer. (I should add, the board isn't really 6 feet high. The picture was taken before we sank the legs into concrete.)
