Habitat: Commonly found in rural areas, but are adapting to suburban areas. Feral swine are land mammals that use water and dig wallows to regulate body temperature.

Native Range: Europe and Asia

Diet: Feral swine are opportunistic omnivores; they eat what they can when they can. Dietary items include crops, bird and reptile eggs, fawns and young of domestic livestock, tree seeds and seedlings, nuts, roots, and tubers.

Local Concern: Feral swine can be aggressive toward humans and can transmit several serious diseases. Feeding habits put feral swine in direct competition for resources with deer, bear, turkey, squirrel, and waterfowl. Additionally, swine use their sharp tusks to root for food and wallow in the dirt. These two activities destroy crops and native vegetation, negatively affect water quality, and can cause erosion.

Means of Introduction: Intentional release, escape from domestication

Other Names: Eurasian boar, Russian boar, wild boar, wild hog, razorback
