National Trust celebrates birth of baby beaver one year after reintroduction
The first beavers in Northumberland for more than 400 years have been stupendously busy. There are new dam systems, as well as canals and burrows, the creation of new wildlife-rich wetlands and, thrillingly, a baby beaver.Whether it is male or female remains to be seen. “Beavers don’t have external genitalia,” said Heather Devey, an expert. “They are really hard to sex. It’s really only through their anal glands that you can tell.”The National Trust has not yet done that check but it is overjoyed by the birth and the wider benefits one year on from the release of a family of four Eurasian beavers on the Wallington estate in Northumberland.Paul Hewitt, the countryside manager for the Trust at Wallington, said their impact on the estate’s environment had been “astonishing”.He added: “This time last year I don’t think I fully knew what beavers did. Now, I understand a lot more and it is a massive lightbulb moment. It is such a magical animal in terms of what it does.”Paul Hewitt, the countryside manager for the Trust at Wallington, said the beavers had created new dams, canals and burrows and wildlife-rich wetlands.

The first beavers in Northumberland for more than 400 years have been stupendously busy. There are new dam systems, as well as canals and burrows, the creation of new wildlife-rich wetlands and, thrillingly, a baby beaver.
