I'm sorry but isn't this just Darwinism in play here? You get natural selection, and various species that are selected against become extinct.
But it's not like it's going to turn into some sort of desert, the area, after forest fires, will be replaced by another species that is presumably resistant to the fungus, and life moves on.
