The vegetation of Phou Hin Poun National Biodiversity Conservation Area is shaped by its
tropical savanna climate, and the rugged, cave-riddled and porous karst terrain. Over 50% of the landscape is estimated to be rocky outcroppings, and most of the rest is dry evergreen forest and scrubland. This diverse landscape is home to 113 species of mammal, 160 species of bird, 81 species of reptile, 47 species of amphibian and 145 species of fish. Another species discovered in the Phou Hin Poun NBCA,
Saxatilomys paulinae, represents a new genus of the
Murinae subfamily, the Old World rats and mice. Mammals known or suspected to live in Phou Hin Poun include the
Indian elephant (
Elephas maximus indicus), the
Indochinese tiger (
Panthera tigris corbetti), the critically endangered
saola (
Pseudoryx nghetinhensis), the
giant muntjac (
Muntiacus vuquangensis), the
Assam macaque (
Macaca assamensis),
François' langur (
Semnopithecus francoisi laotum), and the
black giant squirrel (
Ratufa bicolor). Birds found in Phou Hin Poun NBCA include the
grey peacock-pheasant (
Polyplectron bicalcaratum), the
hill myna (
Gracula religiosa),
red-collared woodpecker (
Picus rabieri), the
sooty babbler (
