Episode Information

Travelling north across the planet, somewhere around latitudes of 60 to 70 degrees, you’ll run out of forest. This land is barren, hostile and bitterly cold – too harsh for even trees to take root. This is tundra. Bleak to the extreme, this icy wasteland harks back to the struggles of the last great ice age. But with some of the most dramatic seasonal changes, it offers rich rewards for those tough enough to take on the challenge. Unsurprisingly, the creatures that live here are some of the most highly adapted and fascinating animals on the planet. From tiny lemmings charging about year round to the giant muskox in their great, shaggy coats ploughing their way through the snowdrift, the tundra is home to all shapes and sizes. And every creature plays a role in balancing this delicate landscape, a place that, despite its remoteness, touches us all.
