Matt meets caravan enthusiasts near Morecambe Bay as they celebrate 100 years of caravanning history. He also discovers how the rise of camping has allowed farms to diversify. Ellie steps aboard a ‘floating apothecary’ run by two trained herbalists who use plants from the forest to make natural remedies. Adam meets top chef Michael Wignall as they take a tour of his favourite suppliers in North Yorkshire, including a Himalayan salt chamber. John goes from fleece to fabric as he tries his hand at shearing with blade scissors and dying unspun wool using spring flowers. The whole process is sustainable, biodegradable and bringing cloth-making back to Bristol. Anita is doing the donkey work in Northern Ireland as she takes part in a tradition stretching back centuries in which donkeys do all the ploughing and planting of traditional Irish crops. And while Steve is on a quest to spot some of the birds returning to the UK this spring, he meets a local artist who makes 3D paper sculptures inspired by nature.
