Well, even more recent reports from Germany also claim that wolves are damn clever to cope even with e-fences. Unfortunately, the question of wild wolves roaming the country now has become a cultural war issue where you can easily guess the left/right divide.

For our ecosystem, a well-managed wolf population is probably a good thing, but rationality is about to go out the window over here. Of course, wolves do not slaughter herds out of pure fun, but also true is that the can wreak quite a bit of economic damage if they break into a holding pen.
