Ellie Harrison and Tom Heap are in the Mendips looking at how this stunning but fragile area is being protected from the invasion of visitors. Ellie scales Cheddar Gorge and discovers the damage cars are wreaking on narrow, winding roads. She also learns how white-clawed freshwater crayfish are being saved from voracious invaders. Tom finds out how the countryside can help transform lives and investigates if the government’s new green subsidy scheme can really deliver for farmers and the environment. Meanwhile, Adam meets one of his heroes, international rugby ref turned farmer Nigel Owens, who is facing his herd’s first TB test.
