Hat Chao Mai NP was designated as the first dugong conservation zone in Thailand. The rich ecosystems of Hat Chao Mai and Mo Ko Libong provide suitable habitats for many terrestrial and marine fauna species such as mammals, reptiles, amphibians as well as birds including migratory species. They are located in the Andaman Sea, deemed to be one of the world's sites with high biological diversity. Mo Ko Libong NHA was initially established to protect habitats of migratory birds but was later on discovered to have large seagrass beds which provide major food source to a large group of Dugong.
