Red squirrels are native to the UK but are a lot rarer than their grey cousins. They live in a few special places across the UK thanks to reintroduction projects.

Found around our coasts during the breeding season, the little tern is a diminutive seabird. Despite its size, it performs remarkable aerial courtship displays.

One of our most common butterflies, the meadow brown can be spotted on grasslands, and in gardens and parks, often in large numbers. There are four subspecies of meadow brown.

Our smallest breeding seabird, the storm petrel is barely larger than a house martin! They mostly nest among rocks or in burrows on small offshore islands.

The yellow, star-like flowers of bog asphodel brighten up our peat bogs, damp heaths and moors in early summer, attracting a range of pollinating insects.

The large white is a common garden visitor - look out for its brilliant white wings, tipped with black.

These large rocky shore fish look like they belong in deeper waters, but they are the find of the day for any rockpooler!

A fierce predator of small fish and flying insects, the brown trout is widespread in our freshwater rivers. It is has a golden body, flanked with pale-ringed, dark spots.

The extensive, golden-brown reedbeds that are formed by stands of Common reed are a familiar sight in our wetlands. They provide an important home for many species, including the rare Bittern.

A scarce tree of England and Wales, the Large-leaved lime is the rarest of our native limes. It is tall and broad, and can be found in forests and parks, where it is frequently planted.
