In this special autumn episode, Dougie is at Mar Lodge Estate in the Cairngorms hoping to get a glimpse of one of nature’s most dramatic spectacles, the red deer rut, while Euan is celebrating the colour red in our autumnal landscape. Conservationist Gabrielle Flinn is in the forest searching for creatures in the invertebrate world that live in woodpiles. Arlene is at Dalkeith Country Park picking acorns to ensure the future generation of historic oak trees, while Nick discovers that pumpkins aren’t just for Halloween and why we should be eating them more. And pumpkins are on the menu for Nick and Dougie in their seasonal outdoor cook-out at the Lake of Menteith.
