Dragonfly (Southern Hawker?) at Colemere
Burrow at Edward German Drive
Feeding at White Lion Meadow
Droppings at White Lion Meadow. Despite the light green colour, these were definitely water vole because of the size.
Survey today at Colemere, near Ellesemere. Our group didn't find any water vole evidence, but we did see a toad, a field vole and a lot of dragonflies, butterflies and damselflies. Not sure yet how the other groups got on.
On the way home I checked White Lion Meadow car park and found feeding and droppings, despite the downpours and fluctuating water levels of late. A stroll up Edward German Drive revealed several burrows (for scale, think of a Pringles tube) and some feeding.
Update regarding the other survey groups' results, from Malcolm Monie's report: Some signs were found in and near the Roden itself in the Wolverley area, but at a low density. Upstream, the brook flowing out of Colemere was examined and despite good habitat, no water vole signs were to be found. A survey 3km farther downstream revealed just one site where a couple of burrows and possible water vole feeding signs were found, as distinct from field voles which were present on the same stretch.
We think mink presence plus only intermittently suitable habitat are the key issues.
