The wild boar is a non-native animal in Arizona, and established feral populations haven’t been documented here as they have in Texas and the Southeast. Open occurrence databases hold only 15 Arizona records for the species, 12 of them photographs. Those scattered records don’t establish its abundance or distribution.

A species Arizona works to keep out

Feral swine root up soil, foul water, and outcompete native wildlife, so where they establish they cause lasting damage. Arizona sits on the arid western edge of that problem. The few records are spread thinly across Mohave, Pima, Pinal, and other counties, consistent with occasional escaped or released animals rather than a breeding, spreading herd. State and federal agencies actively watch for and remove any that turn up, which is part of why the tally stays so low.

Reading a sparse record

With so few observations there is no meaningful seasonal signal here, and the map is best read as evidence of individual animals, not an established range. NatureServe treats the species as exotic in the state and gives it no conservation rank, since a non-native animal is not what the ranking system exists to protect. In Arizona’s southern backcountry, a pig-like animal may instead be a javelina, a native peccary only distantly related to true swine.
