Geographic Range [top]

Range Description:	Small populations remain in Laos, Viet Nam, and Indonesia, but wild Siamese crocodiles are virtually gone in Thailand. In 2000 a single specimen was discovered in Kaeng Krachan National Park in western Thailand, and in 2002 one to three were sighted in Khao Ang Rue Nai Wildlife Sanctuary in central Thailand. An effort has begun to establish additional populations by releasing captive reared specimens in areas of protected habitat
Countries:	Native: Cambodia; Indonesia; Malaysia; Viet Nam Possibly extinct: Thailand Presence uncertain: Brunei Darussalam; Lao People's Democratic Republic; Myanmar
