As you can see from the video, hogs are a huge nuisance to farms and they can destroy massive areas of crops over time if not kept in check. The size of a herd of wild hogs in Oklahoma, where this video was shot, can be more than a dozen and each pig will do his fair share of eating each day. The farmers yield can be greatly affected at the end of the season based on how many hogs are on his land grazing his fields. The smaller farms with a wild hog infestation are the most affected.
Many hunters in Oklahoma, where I am from, have been hired to help farmers keep their land free of the massive herds of roaming stomaches. Many farmers welcome hog hunters to hunt their land for free. The thinning of hogs in some Oklahoma areas is a on going process and requires that hunters continue to hunt them for the scale to stay balanced.
