http://www.woodlanereserve.co.uk/edgeleyroadsummary.htm There've only been a handful of occasions I've been down to that field and seen nothing, so blanks on the chart just mean I wasn't around/was concentrating on another site.
We've always felt at the Whitchurch Water Vole Group that Whitwater Fishery was probably the most important site for w-vs in the area.
But increasingly I'm wondering whether the field off Edgeley Road, where I've had almost all my sightings this year and last, is at least as important a colony - possibly even more so given the way it links other key sites. Although the stream's barely a dribble, the swampy grassland surrounding it is more holey than a Swiss cheese and you have to be really careful where you tread for burrows and trackways. There are latrines every couple of yards, and as I walked down one short length of the bank tonight I heard four separate voles plop into the water. The stream itself forms a kind of T shape and I've only explored the stem; currently the branches of the T are so overgrown that the banks are impenetrable. All the evidence suggests they're just as heavy with voles as the rest, though.
Here's a summary of my sightings from the last few months:
