Lomphat Wildlife Sanctuary is a protected area covering in eastern Cambodia that was established in 1993. It is heavily forested and straddles Ratanakiri, Mondulkiri, and Kratie provinces. It is home to a variety of endangered wildlife such as banteng, 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 woolly-necked storks, and slender-billed and white-rumped vultures, 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.
