The Javan warty pig occurs in Leuweung Sancang Nature Reserve and Meru Betiri National Park in southern Java, Nusakambangan Nature Reserve on the Nusa Kambangan island and in a protected area on the Bawean island.

[3] The Javan warty pig is mainly a solitary creature, but groups of three or four individuals have been sighted.

When a group of individuals is frightened, the recorded alarm call sounds like a shrill whistle.

[3] September to December is thought to be the mating season of the Javan warty pig.

[3] Between 2003 and 2005, captive Javan warty pig in Surabaya Zoo had litters of two to four piglets, born between March and August.

This species threatens the Javan pig not only through resource competition, but also by cross-mating and creating hybrids of S. verrucosus and S.

[7] The most recent conservation project, through the World Association of Zoos and Aquariums, aims to capture healthy Javan warty pigs and breed them in captivity.

One of the problems with this project is finding true S. verrucosus, not hybrids, which brings up another goal of the program, molecular mapping.

Scientists will extract DNA from the wild pigs and record their genetic code to separate hybrids from true S. verrucosus.
