French farmers drove a flock of around 250 sheep around Paris on Thursday to highlight the effect a growing wolf population is having on their flocks.
Previously hunted to extinction across most of Western Europe, wolves crossed the Alps from Italy into the French countryside in the 1990s as a European convention on the conservation of wildlife re-introduced packs back into the wild.
Now farmers are complaining that packs of the government-protected predators are attacking livestock.
There have been 4,800 attacks on sheep by wolves so far this year – 1,000 more than in 2013, according to official figures from the French Sheep Organization (FNO), AFP have reported.
