i was told of a method they use in russia and estonia.

they had people out tracking the animals and when they found a place where the pack were holding up they ringed the area(meaning they had a string with some square pieces of fabric on it each couple of yeards or so)
that apparently kept the pack in that encircled area and then they made a driven hunt with a few packs of dogs and a lot of people standing in the perimeter with shotguns and buckshots, it should be quite a sporting adventure since they then act as vild boar only faster.

just an idea a friend of mine were in russia a few years ago and tryed it, it must have worked to a certain degree as he came home with two pelts(really good quality)

i dont know how hard it would be for you to ring them there, but it is worth a shot if you can drum up the manpower

best
