Western Forest Complex

The Western Forest Complex (WEFCOM) is a large natural conservation area in Thailand, located in the country's western region along its border with Myanmar. It covers 12 national parks and 7 wildlife sanctuaries, and serves as the main biodiversity conservation corridor of the region. Covering 18,730 km², it is one of the largest protected territories in Southeast Asia. The geography of the Western Forest Complex ranges from lowlands to the mountains of the Thai highlands and the Dawna-Tenasserim Hills.^[1]

Because of its large size, the complex supports a diversity of large mammals, including Indochinese tiger, Indochinese leopard, dhole, clouded leopard, sun bear, 10 species of primates (all five of the region's macaques), gaur, banteng, water buffalo, elephant, tapir, and four of Thailand's five deer species. Altogether 153 mammal species, 490 bird species, 41 reptiles, and 108 species of fish are confirmed in the area.
