Shivering and rain-drenched at the side of a pond in Cornwall, a huddle of people watched in hushed silence as a beaver took its first tentative steps into its new habitat. As it dived into the water with a determined “plop” and began swimming laps, the suspense broke and everyone looked around, grinning.

The soggy but momentous occasion marks the first time in English history that beavers have been legally released into a river system, almost one year after the government finally agreed to grant licences for releases.

“It’s a beaver blind date,” said Cheryl Marriott, the director of nature and people for the Cornwall Wildlife Trust, as another made its way into the water.
