A new study shows that the wolves of Yellowstone are affecting elk populations in very surprising ways. Since 1995, elk populations have been declining. It was estimated in 1995 that elk populations in the northern range numbered somewhere between 17,000 and 19,000. In the three winters prior to 2008, the estimated elk population has dropped to somewhere between 6,279 and 6,738.
