Once a mountain kingdom of ancient palaces and emperors, Korea in the 21st century is largely known for its modern cities and decades of conflict. Tensions between North and South may be what defines it to outsiders but beyond the battle scars there is another side to Korea. In the south are large pockets of untouched wilderness where extraordinary animals flourish and Koreans continue to practice age-old traditions in tandem with the seasons and with nature. It is in these connections, rather than in division, that we see the true Korea. At the southernmost tip of the peninsular we follow a pod of bottlenose dolphins through the volcanic islands of Jeju. They click at each other as they encounter a human in their midst, but the dolphins know this diver well - they have shared the ocean with the Haenyeo, or sea women, for thousands of years. We travel onwards to the isolated island of Marado, where three generations of sea women are preparing for a dive. Today is the start of the conch season, and they work hard whatever the weather to maximise their catch. In the grounds of an ancient palace on the mainland, a raccoon dog family takes advantage of a rare event. Just once every five years, hundreds of cicadas emerge from below ground providing an easy feast for the raccoon dogs who voraciously fill their bellies. Those that escape their jaws make for the safety of the trees, where they metamorphosise into their flying form. On the mud flats of Suncheon Bay we find a habitat that is neither land nor sea. Only recently has the ecological value of mudflats been recognised. A staggering 50 per cent of the earth's oxygen is produced by phytoplankton - microscopic algae that are found here in great abundance. That is why the mudflats are known locally as the lungs of the earth. Plankton is far from the only life here - the mud of the bay is rich in nutrients and supports one of the most diverse ecosystems on the peninsula. We follow the story of a young mudskipper who has emerged for his first mating season. His journey to find love is paved with obstacles.
"Magical Appearances" explores how swallows magically appear each spring and asks how did complex and beautiful insects like butterflies suddenly arrive in the summer.The discovery of the swallow’s epic migration and the revelation that butterflies could metamorphose into totally different looking adults were scientific stories both cloaked in mystery and controversy.
The documentary series reveals the extraordinary riches and wonders of the Polar Regions that have kept people visiting them for thousands of years. Today, their survival relies on a combination of ancient wisdom and cutting-edge science. Most Arctic people live in Siberia, either in cities like Norilsk - the coldest city on earth - or out on the tundra, where tribes like the Dogan survive by herding reindeer, using them to drag their homes behind them. On the coast, traditional people still hunt walrus from open boats - it is dangerous work, but one big walrus will feed a family for weeks. Settlers are drawn to the Arctic by its abundant minerals; the Danish Armed Forces maintain their claim to Greenland's mineral wealth with an epic dog sled patrol, covering 2,000 miles through the winter. Above, the spectacular northern lights can disrupt power supplies so scientists monitor it constantly, firing rockets into it to release a cloud of glowing smoke 100 kilometres high. In contrast, Antarctica is so remote and cold that it was only a century ago that the first people explored the continent. Captain Scott's hut still stands as a memorial to these men. Science is now the only significant human activity allowed; robot submarines are sent deep beneath the ice in search of new life-forms, which may also be found in a labyrinth of ice caves high up on an active volcano. Above, colossal balloons are launched into the purest air on earth to detect cosmic rays. At the South Pole there is a research base designed to withstand the world's most extreme winters. Cut off from the outside world for six months, the base is totally self-sufficient, even boasting a greenhouse.
Part one of two. Thirty years ago explorer Benedict Allen lived in Papua New Guinea with the Niowra, a remote people. Broadcast journalist Frank Gardner has always wished to see wild birds of paradise, so Benedict resolves to take him along. The duo set out through some of the most inhospitable terrain on the planet, negotiating swamps, mountains and crocodile-infested waters, heading into the cloud forest. Despite Frank requiring the use of a wheelchair following a shooting incident in 2004, Benedict determines to get him to their destination.
This special, narrated by Andrew Scott, celebrates spring on planet Earth, and the extraordinary tricks that animals and plants find to rise to the new challenges it brings. This magical season brings a burst of new life - but as soon as the air starts to warm, it's a race to wake up and get ahead of everyone else. For many, it's the perfect time to find a mate and raise babies - but for everything, from adventurous grizzly bear cubs and amorous dancing grebes, to flowers in the desert and swifts that fly marathons, spring is about rushing to make the most of the opportunities this busy season brings.
