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

The Brown argus favours open, chalk and limestone grasslands, but can also be spotted on coastal dunes, in woodland clearings and along disused railways.

Shepherd's purse is often considered a 'weed'. It produces a lot of seeds and can be found on cultivated and disturbed land, such as arable fields, tracks and gardens.

The secretive woodlark can be hard to spot. It nests on the ground on our southern heathlands and uses scattered trees and woodland edges for lookout posts.

Largely confined to the north of the UK, the rare pine marten is nocturnal and very hard to spot. However, it can be enticed to visit a peanut-laden birdtable.

In mild years, the spring-flowering primrose can appear as early as December. Look out for its pretty, creamy-yellow flowers in woodlands and grasslands.

A 'weed' of cultivated and disturbed ground, Round-leaved fluellen is a trailing plant with round leaves and yellow flowers that appear over summer.

The chestnut-brown bank vole is our smallest vole and can be found in hedgerows, woodlands, parks and gardens. It is ideal prey for owls, weasels and kestrels.

The brown hare is known for its long, black-tipped ears and fast running - it can reach speeds of 45mph when evading predators.

A king among birds, the goldcrest displays a beautiful golden crown. Our smallest bird, it can be spotted in conifer woodlands and parks across the UK.

A tall and hairy plant, Great willowherb displays pretty pink-and-cream flowers. It can be found in damp places, such as wet grasslands, ditches and riversides.
