Found from Somalia to east and southern Zaire down to the Cape Provinces in South Africa. It can be discovered on Madagascar and on Mayotte Island within the Comoros; nonetheless, it was most definitely put right here by people.
Generally discovered in additional moist habitats with vital vegetative cowl and have a tendency to keep away from drier, extra open areas. May occupy riverine, lowland, swamp, and montane forests in addition to woodland savannas, scrub habitat, and cultivated areas.
Mainly nocturnal, sleeping in self-excavated burrows or in heavy thickets of vegetation in the course of the day. Those dwelling within the southern Cape have a tendency to be extra diurnal in the course of the colder months, suggesting temperature regulation could also be an necessary issue influencing the exercise rhythms in some populations. They dwell in single male household teams containing a number of females and their younger (group dimension vary 4 to 15 people), although each species have been noticed in bigger herds. Family teams are territorial, comparable to different African suids. Territorial encounters are sometimes characterised by ritualized shows and scent marking. Territory sizes differ with location and vary from 0.05-2.5 acres (0.02-1 ha). Adult males play a job in rearing and defending the younger. Males disperse from the natal group, whereas females might stay on the natal territory.
FEEDING ECOLOGY AND DIET
Omnivorous, consuming roots, bulbs, fungi, fruit, eggs, invertebrates, birds, small mammals, and carrion. They use their snouts to root within the floor and may do severe harm to crops in a short while. Field research in Uganda have discovered that bush pigs might comply with teams of monkeys as they forage and feed on the discarded fruits.

The IUCN has designated this species as widespread and regionally ample or comparatively safe, relying on the subspecies. Though the bush pig continues to be comparatively widespread, its distributions are patchy in sure areas. They have been reported to be uncommon outside of protected areas, and they're extensively hunted both for subsistence or for industrial sale of the meat at native markets. In some international locations, poaching inside protected areas is a severe menace. The clearing of some forested areas and conversion to cropland has benefited this species in some areas.
SIGNIFICANCE TO HUMANS
Notorious crop raiders. They are additionally typically thought to move illnesses on to livestock. Eradication applications for these species have been largely unsuccessful as a result of they breed rapidly and are cryptic in nature. Potamochoerus does characterize an necessary supply of meat for food or income in some locations, whereas in others the meat is prevented as a result of it's thought to transmit epilepsy.
