Site description The IBA boundary follows that of the original Yok Don National Park, and does not include the recent extensions that were approved in 2001. Yok Don is situated on the low plateau that covers northern Dak Lak and southern Gia Lai provinces in the Central Highlands. The topography of most of the site is flat, at an elevation of around 200 m. Mount Yok Don is the highest point in the IBA. The Srepok river is the only permanent flowing watercourse at the site. Almost 100% of the site area is under forest cover. The majority of the forest is dry dipterocarp forest, with smaller areas of semi-deciduous and evergreen forest. The canopy of the dry dipterocarp forest is open, and the trees have thick, fire-resistant bark.
Key Biodiversity Yok Don is one of the few established protected areas in Vietnam to support a significant population of the globally threatened Green Peafowl Pavo muticus.
Non-bird biodiversity: Brickle et al. (1998) recorded two threatened primate species at Yok Don: Rhesus Macaque Macaca mulatta and Stump-tailed Macaque Macaca arctoides. The latter species was also recorded by Eames and Nguyen Tu (in prep.). 'Silvered' Leaf Monkey Trachypithecus villosus has also been recorded at the site (Le Xuan Canh et al. 1997).Duckworth and Hedges (1998) report the occurrence of Asian Elephant Elephas maximus, Gaur Bos gaurus and Banteng B. javanicus at Yok Don.

Protection status Although precise information is not available, it appears that Yok Don National Park was first decreed as a nature reserve in 1977. Subsequently, the establishment of a 40,000 ha nature reserve called Tieu Teo Easup was decreed in 1986. It appears that the protected area was intended to have two sectors: one in Chu Prong district, in what is now Gia Lai province, and one in Easup district, Dak Lak province. However, protected areas were never established in these two sites. The decision to establish Tieu Teo Easup Nature Reserve was later used as the basis for establishing Yok Don Nature Reserve in Buon Don district, Dak Lak province. An investment plan to upgrade Yok Don Nature Reserve to National Park status was approved in 1991. The area of the national park given in this decree was 58,200 ha. In 1998, FIPI prepared a revised investment plan for Yok Don National Park. This investment plan proposed expanding the national park by 57,345 ha, to a total area of 115,545 ha. This investment plan has been approved by Dak Lak PPC, and was also approved by MARD in September 2001.
