Feral hogs are a big problem for Tennessee, so a hog season was added in 1999. This plan backfired a bit as it romanticized hog hunting. Hogs started cropping up in places they hadn't been before as people were importing them into new habitats.
Tennessee realized they needed to fix the escalating problem and have eliminated the hog season, so now hogs are not big game they are classified as nuisance animals. "These hogs are very destructive. They do not discriminate on what they eat or what they destroy," said Ben Layton, big game biologist for the Tennessee Wildlife Resources Agency. "This invasive species devastates crops and roots through surfaces to the point it damages water quality with runoff."
A landowner who is having issues with wild hogs can now go out, any time of the day and shoot or trap the hogs. Trapping isn't allowed during other hunting seasons though, unless the landowner gets an exemption as well as an exemption to shoot the hogs at night. From WBIR.com .
