Earlier in 2014 we asked for viewer suggestions as to where we should go to film, and so John Craven and Shauna Lowry head for the Sperrin Mountains in Northern Ireland. Shauna takes a walk into this little-known but beautiful region. She learns it was the birthplace of the great poet Seamus Heaney and visits an old blacksmith's forge made famous in one of his well-known poems. John learns about the unique relationship between one of our most endangered species and fish found nowhere else but Northern Ireland. Shauna takes us on a tour of her old stomping ground around Strangford Lough, before joining John panning for gold on the pretty Ballinderry River. James Wong has the latest from the Grow Wild campaign to get people planting wildflowers. Adam's joined by Dr James Logan as they explore the creepy crawly world of ticks, one of nature's biggest pests, and Tom Heap asks whether a new wave of garden cities really can provide a perfect blend of town and country.
