Western Nghe An Biosphere Reserve, Viet Nam

The Western Nghe An Biosphere Reserve is located in central Viet Nam in mountainous and remote area which is difficult to access. Its climate is strongly influenced by a north-east and south-west monsoon. The topography of the surrounding Annamite mountain range also impacts atmospheric circulation, resulting in significant climatic differences throughout the area. The region hosts some of the most diverse and rich flora and fauna in Viet Nam.
