Chalk

Ray Mears reveals that he spent much of his childhood searching the South Downs for the Adonis Blue butterfly. Back then, they were a rare sight but now, thanks to conservation work, they are easily spotted and Ray gets to marvel at one perched on his finger. Ray's looking at chalk habitats and explains that chalk is made from creatures that lived in the sea millions of years ago. He's on the South Coast and journeys Westwards and, on his way, he spies peregrine falcons, kittiwakes, a wealth of wild flowers and, of course, the Adonis Blue.
