The Amur-Heilong River, which originates in the Khan Khentil wilderness in Mongolia and flows through Russia and China, is one of the world’s ten largest ten rivers as well as one of the last free-flowing rivers left on the planet. An all-female team of scientists from the United States and Australia is bringing this little known river to the world stage, drawing attention to its breath-taking biodiversity and the threats it faces from climate change, illegal wildlife trade, pollution, resource extraction and proposed dam projects. The team is collecting scientific data as well as photos and videos which the women will public in a web atlas of the Amur River, to be shared with the world. Photo credit: Petr Sharov and V. Solkin
