A pair of beavers who were introduced to a nature reserve in February are said to be settling in well and starting to make an impact.
The Eurasian beavers were released into an enclosure at the Old River Bed in Shrewsbury as an experiment, partly to help naturally manage an area of wetland.
Tom Freeland, from the Shropshire Wildlife Trust, said there was evidence of them felling and stripping trees and digging new channels.
In the coming months he said he expected to see more evidence of them changing the landscape.
