Feral pigs are widely considered a nuisance species. The wild hogs cause an estimated $1.5 billion in property damage every year all over the United States on both public and private lands, according to the Mississippi State University Center for Resolving Human-Wildlife Conflicts. They are an invasivespecies that can disrupt entire food chains.
“They’re really bad for the ecosystem,” said Craig Sasser, refuge manager at Waccamaw National Wildlife Refuge in South Carolina. “They out-compete everything in the swamp. They destroy roads and dikes, and they do a lot of damage to nearby farms. The refuge has developed a comprehensive management plan that includes public hunting, trapping, and enclosures to keep the impacts from feral pigs to a minimum.”
