Cumbria is one of the last major strongholds for red squirrels - one of the British Isles’ iconic native mammals, an endangered species, and a national favourite. Lakeland charities, volunteers, businesses and scientists are pulling together to protect these rare animals.

In French Polynesia, there is a place where every year, thousands of groupers gather in secret followed by hundreds of sharks… The photographer, diver and biologist Laurent Ballesta, with his team, wanted to better understand what motivates these fish to wait until the exact day of the full moon to spawn all at once! With the help of researchers from the CNRS of Moorea, they dived and conducted numerous experiments to study and witness this unique phenomenon. Taking advantage of this period of incredible richness, Laurent Ballesta did a record dive of 24 hours at over 20 meters.

The Australian pelican is built for long distance travel. One of the largest pelicans in the pelican family, with a light skeleton and a wingspan of over eight feet, it can be airborne all day and deep into the night, riding far and high on rising thermals. When rare weather systems bring heavy rains, huge numbers of Australian pelicans abandon the sea and coastal waters and embark on a mass pilgrimage to a place a thousand miles inland. It’s the last place you would look for one of their kind, the Australian Outback, one of the driest, hottest places on the planet.

Barely known and never seen, elephant shrews baffle even the zoologists. With their stilt-like legs and long mobile trunk, joined to the body of a large shrew with a golden bottom, they certainly deserve their name - though they are related to neither elephant not shrew! This shy, endangered creature has become the mascot of Kenya’s beautiful Arabuko National Park. The income they attract via tourism pays for the education of local children. The elephant shrew has truly become the Spirit of the Forest.

Every year in northern Canada, polar bears migrate to Hudson Bay to hunt seals. From October to November, while waiting for the ice pack to form, they take up residence on the outskirts of the town of Churchill. Hunted for a long time and now the stars of safaris, the bears have become a tourist attraction and therefore a considerable source of income for Churchill.

It is the foundation of all life. We live on it and from it: the soil. What does the soil do for us? What do we do with the soil? How is it formed? And why is it in danger? The documentary follows an earthworm through its subterranean life cycle and, from here, keeps returning to researchers whose projects are dedicated to protecting the soil.

Whether on land, in fresh water, or in the sea, tortoises, terrapins, and turtles have an advantage. Nature has blessed them with a protective shell that locks out interference and danger.

The mysterious jungles of Thailand are home to some of the rarest wild cats on earth - the Clouded Leopard, The Asian Leopard, The Indian Fishing Cat and the Indo Chinese Tiger.

Told by an old Sagauro cactus, of the many guests which live in its "hotel," from ants to owls nestling in its bark and unlikely co-habitants such as a rattle snake and next door, protected by a barrier of thorn balls, a desert rat.
