Wild boar became extinct in England at least three hundred years ago but in recent years escapees and releases from wild-boar farms have re-established wild populations. A large population near the coast in East Sussex provides Rye’s annual Wild Boar Festival in October with ‘wild boargers’, ‘boargignon’ and other delicacies from the ‘last of the summer swine’.
