A common tree, ash is familiar to many of us for its autumnal bunches of winged seeds, called 'keys'. It can be found in woodlands and prefers damp and fertile soils.

A scrambling plant, Bush vetch has lilac-blue flowers. It is a member of the pea family and can be seen along woodland edges and roadside verges, and on scrubland and grassland.

In early spring, listen out for the 'chiff chaff chiff chaff' song of the appropriately named chiffchaff. It can be heard in woodland, scrub, parks and gardens across the UK.

Famed for its tapping in the middle of the night, supposedly heralding tragedy, the Deathwatch beetle is a serious wood-boring pest. In houses, their tunnelling can cause major damage.

With its familiar features, the Field pansy is a delicate version of a garden favourite. Usually creamy-yellow in colour, it can be seen in fields and on roadside verges and waste ground.

As its name suggests, the scarlet elfcup is a bright red, cup-shaped fungus. It is widespread, but scarce, and can be found on fallen twigs and branches, in shady, damp places.

Seabass is a seafood favourite, appearing on menus throughout the UK. But it's in trouble in UK seas, with much of the seabass we eat imported from European fish farms.

The branching, finger-like projections of this fungus give it the appearance of an underwater coral. Its striking colour and form make it easy to spot, but it is scarce in the UK.
