Auckland Island pig : ウィキペディア英語版 | Auckland Island pig
The Auckland Island pig is a feral (but now conservation-managed) landrace of domestic pig (''Sus scrofa'') found on subantarctic Auckland Island, New Zealand. Its ancestors have inhabited the island since 1807, and, as an invasive species, has had a considerable environmental impact. ==History== In the 18th and 19th centuries, Europeans released domestic pigs on many subantarctic islands. Various introductions of pigs were made to uninhabited Auckland as a source of food for stranded sailors or visiting whalers; the first took place in 1807, with further liberations in 1840, 1842 and the 1890s. By the end of the 19th century, the island held a thriving population of pigs of mixed origin which was largely undisturbed until the late 20th century, interbreeding to produce a distinctive local population.〔(RBCSNZ: Auckland Island Pigs ) accessed 7 January 2008〕
