Feral swine (Sus scrofa) are an invasive species that now occur throughout much of the United States threatening people, property, agricultural crops and livestock, as well as natural resources with their behaviors, parasites, and diseases.  Since 2009, federal and state wildlife management agencies have confirmed the presence of feral swine in a number of counties in Illinois.  In an attempt to protect both agricultural and natural resources from feral swine damage, the USDA-APHIS-Wildlife Services program and the Illinois Department of Natural Resources have implemented an integrated feral swine damage management program.  This successful collaborative approach utilized multiple removal techniques combined with public outreach, education and regulations to culminate in the successful elimination of several feral swine populations, the early detection of emerging populations, and helped to prevent the establishment of a culture of feral swine hunting in Illinois.
