Cambodia is still home to many mammal species that once roamed widely throughout the forests of Southeast Asia. The Lower Mekong Dry Forests Ecoregion holds globally significant populations of several wild cattle and deer species as well as of such iconic species as Indochinese tiger and Asian elephant, while the Mekong River is home to the largest freshwater population of Irrawaddy dolphins in the world. Altogether, not less than 16 globally endangered and two critically endangered mammal species still occur in Cambodia.
