Which entities are included under the umbrella term 'feral swine' when discussing US invasive populations?

Escaped domestic pigs, their hybrids, and imported wild boar lineages

In the context of agricultural and ecological management in the United States, the term 'feral swine' is intentionally broad because all variations exhibit similar, damaging ecological impacts regardless of precise origin. This umbrella classification covers pigs that have escaped from domestic settings and established successful breeding groups in the wild. It also includes populations that have resulted from hybridization between escaped domestic pigs and existing wild boar stocks. Finally, it encompasses lineages that were directly imported as wild boar stock but now reside outside controlled environments. This unified terminology simplifies the regulatory and management approach toward this pervasive invasive category.
