Sometimes called 'Marsh samphire', wild common glasswort is often gathered and eaten. It grows on saltmarshes and beaches, sometimes forming big, green, fleshy carpets.

This impressive beetle digs burrows, lays thousands of eggs and has bee-riding larvae.

A dark, stocky warbler, the Cetti's warbler is most likely to be heard, rather than seen - listen out for its bubbling song among willow, marsh and nettles.

The willow tit lives in wet woodland and willow carr in England, Wales and southern Scotland. It is very similar to the marsh tit, but has a distinctive pale panel on its wings.
