Conservationists spent £29,000 making 20 wildlife ponds in England. Two beavers created twice as many in half the time for free

Conservationists spent significant funds and time digging fewer ponds. Beavers are ecosystem engineers that transform landscapes by building dams. Their work creates habitats and natural flood defenses for wildlife.
