This week we're in Herefordshire where Sean is at Bodenham Lake, site of a huge habitat creation project. When work is complete there will be new spaces for otters, water rail, bitterns and the lake's best known inhabitant, the grass snake. Sean joins Sophie Cowling, the warden here, and her volunteers as they seek out these slippery creatures as part of an ongoing survey. Margherita meanwhile is in a traditional orchard looking to turn its fortunes around with the help of a brew popular in medieval times - verjuice. Made from the juice of unripe apples, verjuice is proving a hit with foodies and top chefs alike. Adam is also in Herefordshire, helping to get another of the country's famous crops in - hops. Matt's getting ready for this year's Countryfile Ramble for Children in Need by meeting Josh, an inspirational 14-year-old whose ambition is to climb a mountain. John is here to announce the winner of this year's Countryfile photographic competition, and Tom is investigating how city-based drug gangs are targeting some of the countryside's most vulnerable children.
