Matt Baker and Margherita Taylor are in Essex. Matt is with the Essex Wildlife Trust on Fingringhoe Wick – a newly created stretch of saltmarsh. It's a race against the tide as Matt helps the team do their first ever winter fish survey. They continue their 'wildlife stock take' by monitoring the mammals that also call this place home.

Margherita Taylor hears about a project to preserve the spirit of the Dig for Victory campaign, before meeting Adrian Thomas from the RSPB. Adrian has done something that's never been done before in the society's 130-year history. Not only has he created the RSPB's first sound archive, but he also released a single using only birdsong!
