Sean Fletcher, Margherita Taylor and Steve Brown are in Northern Ireland. Sean is at the beautiful Lower Lough Erne meeting the two boat-building brothers reviving the traditional clinker boat. He sees the intricate way they are made and gets to sail in one - the first time a wooden clinker boat has set sail on the Lough in decades. Margherita explores the boom in pine marten numbers in Fermanagh and finds that, while it is good news for the local red squirrel population, it is bad news for smallholders. And Steve Brown heads to Killeter, where the local churches are putting on a very special display to mark the 200th anniversary of the birth of Cecil Frances Alexander, writer of All Things Bright and Beautiful.

Matt Baker and Margherita Taylor are in Dorset, where Matt spends time at Lorton Meadows, a nature reserve renowned for its birds of prey. He meets Sam Dallimore, who shows him some of the nest boxes, before meeting up with Jason Fathers, who is installing web cameras. And the stars of the show are the polygamous kestrels - one male with two females, a rare occurrence in the raptor world. Thanks to the webcams, Matt gets a close-up view of the chicks too. Margherita dons her oilskins and tests her sea legs out with the couple who turned their passion for sea fishing into a thriving business. The programme also features Kieran Peree, who gave up his training as an engineer to dive for scallops off the Dorset coast. Adam visits a care farm that is helping people rebuild their lives. Tom discovers how low pupil numbers and a lack of funds mean many rural schools are facing a fight to survive. And Anita meets the first of the contenders in Countryfile's search for a young presenter.
