This week the team are on the Gwent Levels. Matt Baker meets a group of fishermen who are still catching salmon the way it has been done there for centuries. Ellie Harrison is on the trail of a star species that has made an amazing comeback on the Levels. Tom Heap is looking at what is being done to ensure that those most in need in the countryside can access the healthiest fresh food, and it’s the calm before the lambing season storm down on Adam’s farm.
