Feral pig

The feral pig (from Latin fera, 'a wild beast') is a pig (Sus scrofa) living in the wild, but which has descended from escaped domesticated individuals in both the Old and New Worlds. Razorback and wild hog are American colloquialisms, loosely applied to any type of feral domestic pig, wild boar, or hybrid in North America; pure wild boar are sometimes called 'Russian boar' or 'Russian razorbacks'. The term 'razorback' has also appeared in Australia, to describe feral pigs there. A feral pig is a domestic pig that has escaped or been released into the wild, and is living more or less as a wild animal, or one that is descended from such animals. Zoologists generally exclude from the feral category animals that, although captive, were genuinely wild before they escaped. Accordingly, Eurasian wild boar, released or escaped into habitats where they are not native, such as in North America, are not generally considered feral, although they may interbreed with feral pigs. Likewise, reintroduced wild boars in Western Europe are also not considered feral, despite the fact that they were raised in captivity prior to their release. The natural habitats of wild boar are woodlands; however, feral populations root and forage in areas where they conflict with human activities, such as in picnic areas, on golf courses, football pitches, village greens, etc. In the UK, wild boar can be farmed under licence. However, to release them into the wild is illegal. Established populations of wild boar occur in the Forest of Dean, Gloucestershire. These are often active during the daytime (diurnal behavior) and are less wary of people. This is in contrast to populations in East Sussex, which are nocturnal and wary of people. Groups of wild boar have been reported in the Scottish Highlands including Invermoriston, near Loch Ness, and between Newtonmore and Laggan. A group believed to be a mix of wild boar and domestic pig that escaped from a farm, have been seen in the Strathnairn area near Inverness. Wild boar occur elsewhere in the UK according to the Department for Environment, Food and Rural Affairs. It said between 100 and 200 were estimated to be in Kent and East Sussex, and about 20–30 in West Dorset. The practice of introducing domestic pigs into the New World persisted throughout the exploration periods of the 16th and 17th centuries. The Eurasian wild boar (S. s. scrofa), which originally ranged from Great Britain to European Russia, may have also been introduced. By the 19th century, their numbers were sufficient in some areas such as the Southern United States to become a common game animal. Domestic pigs were first introduced to the Americas in the 16th century. Christopher Columbus intentionally released domestic swine in the West Indies during his second voyage to provide future expeditions with a freely available food supply. Hernando de Soto is known to have introduced Eurasian domestic swine to Florida in 1539, although Juan Ponce de León may have introduced the first pigs into mainland Florida in 1521.
