The Dong Phayayen - Khao Yai Forest Complex spans 230 km between Ta Phraya National Park on the Cambodian border in the east, and Khao Yai National Park in the west. It is a rugged mountainous area ranging between 100 m and 1,351 m in altitude, with about 7,500 ha of its 615,500 ha above 1,000 m. The north side is drained by several tributaries of the Mun River, itself a tributary of the Mekong River. The southern side is drained by numerous scenic waterfalls and gorges and four main fast streams that flow into the Prachinburi River.

The site is home to more than 800 species of fauna, including 112 mammals (among them two species of gibbon), 392 species of birds and 200 reptiles and amphibians. It is internationally important for the conservation of globally threatened and endangered mammals, birds and reptiles, among them 19 that are vulnerable, four that are endangered, and one that is critically endangered. The area contains substantial and important tropical forest ecosystems, which can provide a viable habitat for the long-term survival of these species.

The complex also contains the last substantial area of globally important tropical forest ecosystems of the Thailandian Monsoon Forest biogeographic province in north-east Thailand, which in turn can provide a viable habitat for long-term survival of endangered, globally important species, including tiger, elephant, leopard cat and banteng. The unique overlap of the range of two species of gibbon, including the vulnerable pileated gibbon, further adds to the global value of the complex. In addition to the resident species, the complex plays an important role in the conservation of migratory species, including the endangered spot-billed pelican and critically endangered greater adjutant.
