This week Countryfile is in Somerset. Matt Baker is visiting a farm that’s giving budding farmers a helping hand. Helen Skelton’s got a liking for lichen deep in Exmoor’s woodlands, and she’s discovering the creatures that call the north Somerset coastline home. In a special film for Comic Relief, Sir Tony Robinson will be visiting a charity that’s making a real difference to people’s lives. Adam Henson is in Cheshire on a shopping trip with a difference - he’s buying livestock, and Tom Heap is looking at whether enough is being done to protect our coastal waters.
