This mostly pristine forested park is home to a large variety of important animal and bird species.

[1][2] Phou Xang He National Protected Area is located about 100 kilometres (60 mi) east of Savannakhet, near the village of Phalan and covers parts of Assaphone, Thaphalanxay, Phin, Xepon and Viraboury districts.

[1] Threatened animal species in the park include elephant, tiger, leopard, clouded leopard, black crested gibbon, François' langur, giant muntjac, gaur, pygmy slow loris, dhole, Asian black bear, sun bear, banteng and large-spotted civet.

Phou Xang He's large area and relatively pristine state make the park important in conserving these species in an undisturbed habitat.

Road development and improvement may increase opportunities for illegal trade in wildlife and forest products.
