Anne is in Perthshire meeting the woman keeping an eye on the Fortingall Yew, perhaps Europe's oldest tree, discovering the story behind this piece of living history. Following this winter's storms, Dougie assesses the damage to the forests in the worst hit areas of north east Scotland.
Meanwhile, JJ is in Ayrshire finding out how trees have inspired one artist to discover her creative side using a chainsaw, and Arlene meets the man who has devoted his career to looking after trees.
