Densities vary depending on conditions, with about onepig per square kilometre in woodland, forest and grazing land, and as many as 10–20 in wetlands and seasonally inundated floodplains. Boars generally roam alone over an area of up to 40 square kilometres, while sows range over areas smaller than 20 square kilometres. During dry conditions, groups of up to 100 pigs may gather around waterholes.
