Amur: Asia's Amazon

The Amur’s coastal delta is one of the richest ecosystems on earth. Nourished by the mighty river’s enormous sediment load, the Sea of Okhotsk is a marine hotspot of biodiversity with arctic and subtropical species living side by side.

Commonly known as the "Black Dragon", the Heilong-jiang forms a natural border between China and Russia and, free of dams and bridges, is a sanctuary for wetlands and wildlife.

Moving upstream into Mongolia, the itinerary of the series leaves behind the boreal woodland wilderness of China’s extreme north and Siberia’s south to follow the Amur’s two westernmost tributaries across the planet’s vastest wild grasslands.
