Wild boar, often called feral swine in Ohio, aren’t a native part of the state’s wildlife. They descend from escaped or deliberately released domestic pigs and Eurasian wild boar, and the state treats them as an invasive nuisance species rather than game to be conserved. The 15 scattered records gathered since 2000 don’t point to an established, welcome population.

Reports show up in most months with a small September bump, but the pattern is too thin to say much about real activity. Ohio hasn’t assigned the species a NatureServe rank, since that system tracks native wildlife conservation status, not an unwanted introduced species.
