A look at some of Britain's wildest and wettest corners, and their inhabitants. Beavers display their skills as landscapers, a water spider constructs its own air tank, and starlings put on a head-turning display to keep a peregrine falcon at bay.

Britain's forests contain booming populations of previously rare wild boar and goshawks.

Only the hardiest of beasts survive in Britain's mountains and uplands, including the golden eagle and its prey the mountain hare, plus 400,000 red deer, the flamboyant black grouse, and sheep who have grazed for centuries.
