The sanctuary includes an area of 1,155 km² of Khiri Rat Nikhom District and Ban Ta Khun District, north of Khao Sok National Park and Ratchaprapha Dam. Most lowland areas in the Khlong Saeng valley were flooded with the construction of the dam and the creation of Cheow Lan Reservoir. This now flooded area was the only site in Thailand where Storm's stork (Ciconia stormi) was confirmed to breed in 1986.^[2] Khlong Saeng is believed to be the habitat of about 200 wild elephants and 400 gaur. The population of clouded leopards and Asian golden cats is thought to have increased. In 2019, cameras were installed in the sanctuary to take pictures of endangered and protected animals in a 750,000-rai area north of the Ratchaprapha Dam. Photos captured rare animals such as clouded leopards and Asian golden cats. Traces of other rare animals such as black tigers and leopards were also found.^[3]
