Now a protected species, beavers were once widespread in Britain, but they were hunted to near-extinction by the 16th Century.
A nationwide scheme to reintroduce the animals is being run by Forestry England, in collaboration with Natural England and the Beaver Trust.
The animals in the Wyre Forest have built many dams that help to reduce flooding, since moving into the enclosure, including one stretching 30 metres.
“We’ve now got probably about eight to ten smaller dams that have been built,” Boles added.
“Some of them are really quite small and dinky if you like, so they might be some of the younger beavers that have been doing that.”
