It's very overgrown on this stretch, but that's great for the voles - more food and cover.
A single water vole dropping laid on top of a feeding station.
Below, three feeding stations and a vole-cut piece of sedge.
The voles at Black Park Road are pretty shy, but there's clearly a thriving population on that stretch. In the tiny section I looked at by the public footpath there are lots of field signs, and I could hear several chomping away.
