I admit I was gutted when the voles moved up from White Lion Meadow car park (near Tesco), but their absence has made me look further afield. This evening I had a walk through Whitchurch Country Park and found stacks of water vole prints under both bridges, and also this possible otter spraint in the same place the survey group found one last year. It certainly smelled of fish oil, so I can't think what other type of scat it can have been. I include this photo of a feeding station, but not at all confident it isn't field vole!
On the way back to the car I saw a water vole nip across the brook from one bank to the other.
Added 9/6/2007 - I'm now not sure these footprints are water vole. they may be rat, more splayed out then usual because of the soft mud.
