Are wild pigs a problem in America?



  1. 0 Votes

    Domestic pigs that have escaped into the wild, as well as wild boars introduced from Europe, have caused significant environmental damage in the US – mainly in the south, southeast, and Hawaii. Wild pigs damage local ecosystems by digging up the ground, preying on native plants and animals not adapted to pigs as predators, and rooting up vegetation to a degree that leaves the soil vulnerable to erosion. As with most invasive animal species, the problem is most serious in ecosystems that evolved in isolation and where local plants and animals are not adapted to large, omnivorous mammals. Consistent with this logic, Hawaii is almost certainly the US state where wild pigs have inflicted the most damage on local flora and fauna.
