Dong Phayayen-Khao Yai Forest Complex
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. The site is home to more than 800 species of fauna, including 112 mammal species (among them two species of gibbon), 392 bird species and 200 reptile and amphibian species. It is internationally important for the conservation of globally threatened and endangered mammal, bird and reptile species, 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.

Description of values
Significant natural habitats for a diversity of species, including threatened and endangered species.
Conservation of migratory bird species.
Illegal logging operations for the high value timbers have become increasingly sophisticated and violent confrontations between loggers and park rangers often occur. The rate at which illegal logging has increased in recent years had outpaced the ability of park officials to respond and address this issue (IUCN, 2014a) but the IUCN mission in 2017 noted the ongoing efforts being made to address this threat, including at the national and international levels. These efforts will need to be further strengthened by international cooperation on law enforcement and prosecution, to ensure a strict control of the supply chain and prosecution of foreign loggers arrested in Thailand and who were deported largely without prosecution or penalties even though forestry law, immigration laws and others have been broken. Although the State Party has reported that cases of illegal logging of Siamese rosewood have been decreasing since 2014 (State Party report, 2017), new cases continue to be reported in local media, and the threat clearly remains very high.
In addition to these larger scale dams, small scale check dams have been built in many streams in all parks over the last 5 years, in an effort to help raise water tables and to provide drinking sources for wildlife. However, no ecological studies appear to have been conducted prior to building these dams, and their ecological impact, particularly on migratory species of small fish, is unknown (IUCN Consultation, 2017).
The importance of this site for Thailand’s substantial tourism industry should also be further quantified to ensure that this is well managed and sustainable and that benefits flow back to local people and communities.
