Beavers are the engineers of the animal world, creating wetlands where wildlife can thrive. After a 400-year absence, beavers are back in Britain!

Considered Britain's most threatened butterfly, the high brown fritillary can be only be found in a few areas of England and Wales.

A summer visitor, the wheatear is a handsome chat, with black cheeks, white eyestripes, a blue back and a pale orange chest. Look for it on upland heaths and moors.

With tiger-like stripes, red fins and a humped back, the perch is a striking fish. It can be seen in lowland waterbodies and waterways across the UK, often in shoals.
