Herds on the Move: Caribou and the Tundra's Greatest Show

Join host David Hale on an Arctic adventure exploring one of nature's most spectacular phenomena - the great caribou migration. Discover how these remarkable animals navigate over 1,500 miles annually across some of Earth's harshest terrain, following ancient pathways encoded in their DNA. Learn about the intricate timing of caribou migrations, from winter retreats in boreal forests to summer calving grounds on the tundra's coastal plains. Explore the deep cultural connections between indigenous Arctic peoples and caribou herds, particularly the relationship between the Gwich'in people and the Porcupine Caribou Herd. Understand how modern satellite tracking reveals the incredible navigation abilities of these Arctic wanderers and the complex social structures within massive migrating herds. Examine the challenges climate change poses to traditional migration routes, including altered vegetation patterns and changing snow conditions. Discover the traveling ecosystem that follows caribou herds, from wolves and bears to eagles and foxes, all participating in this grand Arctic procession. This episode reveals how caribou migrations represent more than just animal movement - they're demonstrations of adaptation, resilience, and the vital importance of protecting wildlife corridors in our changing world.
