Wild boars were introduced in North Carolina in 1912 when a shipment of twelve boars arrived at a hunting lodge near Robbinsville. By 1920, the original number had grown to over one hundred. Several escaped their pens and spread into the Great Smoky Mountains National Park. U.S. Forest Service officials sponsored several hunting expeditions to kill the wild boards because of their threat to native wildlife. Their population has been reduced, but it has not been eradicated.
