The mission of Watershed Management Protection Authority (WMPA) is to provide a future with secure forest, productive agriculture, secure land tenure, and positive human development within the Nakai Nam Theun National Protected Area.

Nakai Nam Theun National Protected Area (NNT NPA) represents Lao PDR’s largest and most diverse natural forest area and has an outstanding conservation value for South East Asia. Three of the last five large mammals to be discovered or re-discovered world-wide occur in Nakai Nam Theun NPA. The most remarkable of these discoveries is the Saola (Pseudoryx nghetinhensis) endemic to the isolated Annamite Ranges region on the Lao-Vietnam border. Nakai Nam Theun NPA also represents a global stronghold for four threatened primate taxa including the Endangered Red-Shanked Douc (Pygathrix nemaeus), Vulnerable Pygmy Slow Loris (Nycticebus pymeaus), Globally Threatened Francois Langur (Trachypithecus francoisi) and Endangered Southern White Cheeked Gibbon (Nomascus siki) and is home to some 430 bird species including the Endangered White-Winged Duck (Cairina scutulata).The NNT NPA forms the core of a series of connected conservation areas straddling the Lao-Vietnam border. Collectively the conservation areas represent the most important protected area in the Lao-Cambodia-Vietnam Region and act as one of the last remaining biodiversity corridors in South East Asia.
