/ Wild pigs continue to disrupt local agriculture and ecosystems, especially on island habitats, according to researchers at the University of Hawaiʻi at Mānoa and the Royal Melbourne Institute of Technology, Wild pigs are unique among invasive species because they can act as both top predators and destructive herbivores, researchers say. Hawaiʻi’s first pigs originally came with Polynesians who brought an Asianic breed of pig. James Cook’s arrival brought a European type of pig. The two pigs hybridized, and researchers believe this is when they became feral. Wild pigs act as an “ecosystem engineer.” They can root and dig enough to alter the soil structure, which fundamentally changes the ecosystem type.
