Dong Phayayen - Khao Yai Forest Complex

The second largest protected forest complex in Thailand: Dong Phayayen – Khao Yai (DP-KY) is about 6,200 and composed of 4 national parks and one wildlife sanctuary including Khao Yai, Thap Lan, Pang Sida, Tha Praya National Parks, and Dong Yai Wildlife Sanctuary.

Tigers DP-KY can be recovered for 100 adult tigers if managed properly: If consider the same calculation tiger population of WEFCOM, DP-KY, with 6,200, can hold approximately 100 adult tigers, 20 adult male tigers and 80 adult female tigers.

The last tiger in Khao Yai National Park: In 2001, the researchers set up camera traps in Khao Yai and captured only one tiger, which many people suspected the last tiger in Khao Yai. They have no tiger photographs from Khao Yai Since.

Hope for tiger recovery in Dong Phayayen: During 2018-2019 the researchers from Dong Phayayen-Khao Yai Wildlife Research Station captured about 18 adult tigers in the area in the middle of Dong Phayayen side, including Thap Lan, Pang Sida, Ta Praya National Parks and Dong Yai Wildlife Sanctuary. This gives a high hope for conducting tiger recovery in DP-KY.


Recovering tiger prey is the most important goal for recovering tigers in Dong Phayayen-Khao Yai: The effort to recover tigers and prey in DP-KY has evoked movements of various sectors in Thai society. The National Science and Technology Development Agency (NSTDA) has recognized the importance of the efforts and supported the coordinated endeavor led by Faculty of Forestry, Kasetsart University for a 5-year project (2018-2022) aiming for habitat improvement for boost up food sources for tiger prey, especially gaur, banteng, and sambar in Thap Lan and Pang Sida National Parks. If successful, it will help speed up the tiger recovery process in DP-KY.

Thailand first wildlife corridor for tiger and other wildlife: In 2019 the Department of Highways opened the first wildlife corridor worth US$40 million linking Khao Yai and Thap Lan National Parks. In the near future we hope that tigers from Thap Lan will be recovered and use the wildlife corridor to cross from Thap Lan to Khao Yai National Parks.
