Greater Mekong
The Greater Mekong spans Cambodia, Laos, Myanmar, Thailand, Vietnam and the southern province of Yunnan in China, and contains some of the most biologically diverse habitats on our planet.
Since 1997, over 1500 new species have been described by science in the jungles, rivers and even urban areas of the Greater Mekong. This is in addition to a number of rare species including crested gibbon, tigers, Mekong Irrawaddy dolphin and the elusive Saola, which has been described as the most remarkable large mammal discovery of the last 70 years.

Protecting the Greater Mekong
WWF supports a ten-year delay in the approval of lower Mekong river mainstream dams to ensure a comprehensive understanding of all the impacts of their construction and operation. Immediate electricity demands can be met by fast tracking the most sustainable hydropower sites on the lower Mekong’s tributaries, and WWF is developing tools to help assess which tributaries can be developed for hydropower without compromising the ecological integrity of the lower Mekong basin.
On climate change, WWF is devising ways to enhance the region’s resilience to the current and forecast impacts of climate change. Asia’s first regional climate change agreement that incorporates climate change adaptation into existing development plans is being promoted as on such solution.
With offices in Cambodia, Laos, Thailand and Vietnam, WWF Greater Mekong is working with government, industry and NGO partners to secure a future where people's daily actions support biodiversity conservation and sustainable use of natural resources, upon which the quality of life for the people of the Greater Mekong region depend.
