In this special episode, Ellie joins Adam and his team for 48 hours of hectic lambing action. She may be the rookie in Adam's lambing shed, but Ellie quickly gets to grips with multiple births, touch-and-go adoptions and the emotions of the life-or-death decisions faced each day during this busiest of spring seasons on the farm. Tom Heap finds out why mountains of wool, historically the nation's most valuable sheep product, are now piling up in warehouses across the country. In Cumbria, Hannah Jackson – the Red Shepherdess - meets young upland farmers bringing new ideas to this traditional form of sheep farming. Plus how to count sheep using an almost forgotten Celtic language system.

Joe Crowley discovers how science is helping better understand nature on Bedfordshire's Greensand Ridge. He gets up close with avian giants, finding out how the world's longest-running bird survey helps monitor heron numbers. He gets on his bike to help map the amount of plastics polluting our rural landscape, and is out on toad patrol, helping create a new national DNA database to discover why these amphibians are in trouble. As spring appears, Adam finds out if his farming gambles are paying off, Tom investigates whether the UK's environmental ambitions will change the face of our national parks and areas of outstanding natural beauty, and naturalist Dan Rouse captures the seasonal spectacle of thousands of oystercatchers on the Gower Peninsula.
