An increase in dormice has been indicated through footprint tunnels, placed in hedgerows as part of the scheme.
Project officer Julie Grainger said: “The footprints that are in the tunnels could be wood mice or dormice.
“We need to analyse the little patterns that are on there and see if we can work out which ones they are.”
More than 200m of new hedgerow has been planted – a highway for all sorts of wildlife to travel along.
Ms Cragg said: “We’re very keen to put it back into the landscape, because it connects some of our existing hedges over to Monkwood.
“[It] will act as a sort of corridor, wildlife corridor, through the landscape for small mammals like dormice, but also navigating bats and all sorts of things.”
