There is an interesting opinion piece in the Honolulu Advertiser about invasive species, by columnist Lee Cataluna, referring to this recent report about the feral pig (Sus scrofa) problem in Manoa. In it, she speaks of feral pigs as a problem of Honolulu's urban elite, saying that while they do not want the pigs rooting around in their gardens, they also cringe at the thought of an organized culling. Ms. Cataluna notes that in a more rural area she visited, people just treated the pigs as something to be hunted down, and were even selling the "ono" (delicious) pork as a way of raising funds for the local school.
We typically hear about feral pigs with respect to their ability to damage wild habitats, rather than their negative interactions with people. Though Manoan residents note environmental damage as one of their reasons for concern about the feral pigs, my guess is that their interest has been piqued mostly by the risks to their flower beds and pets.
