Greensand Ridge

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.
