Pest Risk Assessment for Feral Pigs in Oregon

Feral pigs, wild boars, and hybrids either currently inhabit, or have been successfully introduced to every continent except Antarctica, and many oceanic islands. There are thirteen current known localities of feral pigs in Oregon (see Appendix A), distributed in various locations in southern and central Oregon. The biology of feral pigs indicates that these animals are capable of inhabiting virtually all available habitat west of the Cascade mountains, and the majority of the habitat east of the Cascades, with preference for riparian regions. Reports of feral pig biology and ecology in other regions in the United States, as well as around the world, give no indication of any limits to distribution, with the exception of high elevations
