According to NCWRC hogs in eastern NC are considerd feral (escapees from the farm) some local herds remained that way for years reverting back to "wild" only to a certain extent (pretty wild in some cases),BUT thanks to some YAHOOS releasing true strain Russian Boars illegaly imported from other areas we are seeing more of a mixed herd and increasing populations. They are causing problems in some areas for the farmers (find one and you probably found a place to hunt) I'm waiting and fearing the day some kid fishing his local creek gets attacked by a territorial boar or protective momma sow(I hope not)not to mention the damage that they are doing to native habitat (deer and turkey food) Hope this helps check the regs at
