The Western Forest Complex, straddling two countries - Thailand and Myanmar - and comprising 19 national parks and wildlife sanctuaries, is a main biodiversity conservation corridor of the region. Covering 18,730 square km, it is one of the largest protected territories in South East 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 a rich large mammal fauna, including tiger, 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.
