A family of beavers has been released into a Lincolnshire river to live in what officials claim is England’s largest beaver enclosure.
The four animals are expected to help return the West Glen River near Grantham to a more natural course after centuries of being straightened and deepened to drain farmland.
The family will live in an enclosure measuring about 200 hectares (494 acres) which includes 20,000ft (6,000m) of specialist perimeter fencing and shelters made by community volunteers.
Claire Barrett from Nattergal, which runs the site, said: “The beavers will be our nature engineers and create an amazing complex of wetland habitats which bring in other species to enjoy the landscape.”
