In UK, the meat from wild boar (Sus scrofa) has recently been served by gourmet restaurants. Farmers here have raised them in captivity to supply the market. The meat is apparently more tasty than ordinary pork.

However, some farmers illegally released their stock into the wild, and other boar escaped. The wild population is now around 1000, scattered around southern England, particularly the Forest of Dean.
They cause no end of problems, attacking ramblers and charging out of the bushes to savage dogs and people.

The British Wildlife organisations are very concerned and would like the problem to be addressed.

While there used to be wild boar throughout our forests in the Middle Ages (they were considered excellent game for hunting) they had died out hundreds of years ago until this recent 'invasion'.

African wild boar (Hylochoerus meinertzhageni) are huge and have vicious, sharp tusks which can slash flesh wide open. Thank goodness the gourmets in UK didn't decide they wanted to eat those!
