There are for example populations of threatened birds, including colonies of breeding water birds such as the world's largest populations of the near-threatened Asian Openbill (Anastomus oscitans), and other birds such as the wintering Black Kite (Milvus migrans). Endemic mammals that remain are the Limestone Rat (Niviventer hinpoon), Neill's Long-tailed Giant Rat (Leopoldamys neilli) and the near-endemic Thailand Roundleaf Bat (Hipposideros halophyllus).
