The park's main forest type is semidry evergreen forest. Upland forest is considered moist evergreen forest. Animal species include the endangered
yellow-cheeked gibbon. Wild elephants once roamed the area, but now only domesticated ones are found. Bird life includes the
grey-faced tit-babbler, found only in
Indochina, and rare
hornbills. The wetlands are home to the
Siamese crocodile,
hog deer and
green peafowl, all endangered. ==Threats==
