Abstract

Feral swine (Sus scrofa; Figure 1), also known as feral hogs, feral pigs, wild pigs, wild boar, or other similar derivations, are a non-native species considered to be one of the most destructive invasive terrestrial vertebrates in North America. While feral swine populations remained relatively small and confined in the continental United States following initial introductions by European explorers during the 15th century, substantial range expansion has occurred across every geographical region of the United States (Figure 2). This expansion has primarily been attributed to human-mediated movements, predominately for the purpose of establishing populations for recreational hunting, and facilitated by feral swine’s highly adaptable biological and behavioral traits (e.g., habitat generalist, opportunistic omnivore, extremely high reproductive rate). Consequently, ecological, agricultural, and urban/suburban damages and human health and safety risks have increased substantially across the United States, requiring extensive management efforts to mitigate their destructive impacts.
