A pregnant female was spotted in May and the kit has been filmed swimming, the National Trust says.

“We are thrilled that after an absence of around 400 years we now have beavers back and breeding.”

She added: “The beavers have put a lot of effort into building and maintaining their lodges and getting their family settled, showing great perseverance and resilience during their relocation and then during the floods we’ve had over the last year,”
