S. celebensis is a medium sized pig which is still found in abundance in central, east and south-east Sulawesi. It is now scarce in south and north-east Sulawesi and may be extinct on nearby Selayar Island. It also occurs as a native form on the adjacent islands of Buton, Muna, Kabeana, Peleng, Lembeh and on some of the Togian Islands (Burton and Macdonald 2006). As originally shown by Groves (1981), this species has also been truly domesticated and widely transported to other islands, where it has also often hybridized with S. scrofa, thus giving rise to a variety of introduced domestic and feral pig populations amongst the Indonesian the islands of Flores, Timor, Simeuleu, Seram, Buru and Nias Islands. Domesticated forms of S. celebensis can be seen on the islands of Roti and Sawu (Groves 1983, Bell 1987). Wild pigs from Halmahera, previously referred to as feral S. celebensis, have been shown to have greater genetic affinity to the New Guinea pigs (Larson et al. 2005).
