The worlds biggest freshwater fish and 4 out of the top ten giant freshwater fish species can be found in the Mekong River. The single most important threat is the hydropower dams in the lower Mekong and large tributaries.
A new monkey, a self-cloning skink, five carnivorous plants, and a unique leaf warbler are among the 208 species newly described by science in the Greater Mekong region during 2010. The region is an integral part of one of the top five most threatened biodiversity hotspots in the world.
Spanning five of the world’s 13 tiger range states, the Greater Mekong region possesses the largest combined area of tiger habitat in the world today. Estimates vary significantly but it is thought there could be as few as 350 Indochinese tigers remaining in this region, down from roughly 1,200 in 1998.
