Western Forest Complex

The Western Forest Complex, straddling two countries, Thailand and Myanmar, including 19 national parks and wildlife sanctuaries, is 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.
Because of its large size, it supports diverse large mammal fauna, 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.
