Lomphat Wildlife Sanctuary is a heavily forested area straddling Ratanakiri, Mondulkiri, and Kratie provinces in eastern Cambodia set aside by the Cambodian government as a wildlife preserve. With an area of 250,000 hectares, it is home to a variety of endangered wild animals such as banteng, tiger, gaur, dholes and sun bear, as well as leopards, Eld's deer, sambar deer, muntjacs and wild pigs. In addition, a number of rare birds are present: surveys have confirmed the presence of green peafowl, greater and lesser adjutant storks, sarus cranes, oriental pied hornbills, giant ibises, white-shouldered ibises, milky and wooly-necked storks, and vulture sp. (slender-billed and white-rumped), which are increasingly rare in most of South and Southeast Asia.
A Chinese company is planning to build a dam on the Srepok river, which would flood the surrounding villages and inundate more than a third of the sanctuary.
