Greenfields water vole survey: these tiny mud-coloured droppings (lower right) are what we're looking for
...and this is where we're looking, in amongst this vegetation. Needle in a haystack doesn't come close.
It's helpful when animals leave their scat on prominent places
as this Grindley Brook otter has done.
I was watching for water voles and seeing none when this polecat slunk past on the far bank. All mustelids will take a vole if they get the opportunity, and there are already weasels and otters recorded for this stretch. However I'm hoping the polecat doesn't impact too far on the Edgeley Road colony. There are good vole numbers here, at least.
