A land of fire and ice, the volcanic peninsula of Kamchatka lies in Russia’s far east. With the land constantly being reworked by eruptions and landslides, this far-flung part of the country is dangerous, but incredibly fertile. Heading right into this magical land, this stunning film follows soaring golden eagles, scavenging wolverines, young red foxes and local brown bears partial to a dip in a natural hot spring.

While Asiatic black bears hang from the trees and chipmunks search for food, the spotted sika deer travels to the coast to supplement its diet with kelp. The presence of deer on this open ground attracts the region's big predator, the Amur tiger. But the largest cat in the world has dangerous enemies itself: poaching and habitat destruction are an ever-present threat to tigers in the Ussuriland region of Russia.

Siberia is vast and covers most of Northern Asia. Encompassing roughly ten percent of our planet's landmass and sparsely populated, its name has become synonymous with the harsh environment, where bitter and relentless cold rules for much of the year. Accounting for around 10 per cent of the world’s dry land, Siberia is famous as a brutally cold place. Yet it is home to a diverse range of habitats and animal life – including musk deer, camels, gazelles and the extraordinary Siberian salamander, which can spend years encased in -40°C ice and still survive. Exploring from the frozen north to the southern steppes, this is the real Siberia.

From high snowy peaks to baking deserts, the Caucasus is much more than a simple mountain range. With habitats including forests, alpine meadows and arid salt flats, like the rest of Russia it boasts a dazzling array of wildlife. Home to wild boars, Eurasian lynx, long-eared hedgehogs, bezoar ibex, rare highland European bison and the truly bizarre glass lizard, this area is another jewel in Russia’s wilderness crown.

The Russian Arctic is one of the world’s most extreme habitats, yet it is a haven for polar bears, lemmings, arctic foxes and walruses. In late August, massive muskoxen bulls gather together to compete for mating dominance. Each bull can weigh 400 kilogrammes and charge at a speed of 40 kilometres an hour; a head-to-head impact can be heard more than a kilometre away.

Travel through the majestic Primeval forests of the Urals. This Russian sanctuary is a land of extremes where giant deer and half-tonne leviathans. Eurasian elk make seasonal journeys in search of food. Unlike other deer, Eurasian elk are normally solitary and for pregnant females, the stress of meeting leads to fighting. As the snow retreats, opportunists like lone wolves advance to feed on winter's victims…

In far eastern Russia lies the legendary Kamchatka Peninsula, a remote haven between the Sea of Okhotsk to the west and the Pacific Ocean to the east. From volcanoes to endless shorelines, most of Kamchatka is a pristine wilderness, rich with huge bears and plentiful salmon, preserved by its remoteness…perched on the edge of the world.

From Lake Baikal – the deepest lake in the world – to the Volga River and Caspian Sea, Russia's inland water is a treasure trove of biodiversity.

From icy coastal tundra in the Arctic Circle to treeless grass steppe in the south, Siberia is home to ancient forests and the world’s deepest lake. Known as the ‘sleeping land,’ much of Siberia is encased in ice and snow for most of the year. Animals here must adapt to survive and thrive, or perish in this frozen land.

In far eastern Russia, mountainous boreal taiga in the north meets temperate rainforests in the south. Stretching over two million square miles, it’s a vast region about twice the size of India. An unfathomable expanse of forest intersected by clean rivers, this is Russia’s richest diversity hotspot. Here species find their last refuge in a wild place like no other.
