Steve Brown goes on a whistlestop tour of the place he calls home - the Isle of Sheppey. A flat landscape typified by saltmarsh, sea and big skies, this is a wilderness full of wildlife. The programme spends the day immersed in nature at Elmley Marshes on the north Kent coast. It's the country's only family-run farm that is also a designated national nature reserve.With waders within the wetlands, livestock on the saltmarsh that snakes down to the sea and raptors soaring high in the enormous skies, Steve gives viewers an insight into the landscape he loves. The programme also looks back at some of Countryfile's favourite forays on to marshland, on the seas and in the sky.
