No, Kolmården is not part of the actual reserve, but sits right next to it. A huge insvesment like Wildfire could disrupt cultural/social, ecological and even economic values in the surrounding area, which means that it is Länsstyrelsens business. To take your argument to extreme would be to place a nuclear plant in you backyard and say that "you other people have no authority here, because this is my land"...
And just for the record: it might seem as if i'm trying to bug the hell out of you, but I am only trying to be realistic and look at both sides. At this point it is not granted that Wildfire will be built. My personal believfs (and hopes) is that they will, in time, get a permit for Wildfire. But, as I said before, at this point it is not granted that they will.
