I don't know where you live and hunt in Appleby, but I can assure you that the hogs have not been eradicated. I hunt the Lanana bottom just south of Appleby, and the hogs move through our place on a regular basis. I have been hunting the same place for 13 years, and they do seem to have become more "nomadic" but are definitely still there.
Here is a picture of my son with a hog that he killed a couple of weeks ago.
