Wire Puzzle

Why would someone leave two pieces of wire netting on the ground in the middle of the woods in one of the most remote parts?

And quite a distance away why this bag, full of wire netting in an equally remote place? We're used to seeing items dumped but not as far away from a car park as this. Nowhere that I know is chicken wire like this used for fencing so why?

Even more of a wire puzzle, how can this barbed wire fence still be here. I can find nobody to defend its existence and it is, of course, barbaric.
