I've looked a few times at White Lion Meadow, the colourfully named town car park near Tesco, but haven't seen anything other than this rat climbing a bramble. But I know the voles are there because they're leaving their carefully-cut lengths of reed neatly piled on the banks.
This blog charts the fortunes of water voles in and around the Whitchurch area, North Shropshire. Water voles are one of the UK's most threatened mammals, extinct in many counties, and so it's vital they receive as much monitoring and protection as there is going. Here in Whitchurch we're lucky enough to have them right in the middle of town - how cool is that?
