Wiped out

The wild boar wandered into Sweden after the last ice age. But they were hunted by humans for their meat, and also for the crop damage they caused. They were wiped out completely in the 17th century.

...but reintroduced

Today, there are wild boars in large parts of southern and central Sweden. The population has grown from a few individuals that escaped from wildlife enclosures. Their range has expanded rapidly, because the sows produce litters of about six boarlets. The current population originated with some wild boars that were introduced from Germany and Poland; there has also been some cross-breeding with domestic pigs.
