Just read the article on one of aol's main pages too so it must be true. ;o) I was just in Yellowstone Friday and had a great time visiting what is truly an amazing national treasure. My 2 day tour of the area certainly doesn't make me an expert on the local situation, but there were elk all over the place. Bison, however, were EVERYWHERE. The published literature in the park mentioned that bison numbers were being controlled by hunting on the neighboring land and mentioned Nez Perce and other local tribes exercising treaty rights to hunt them. No details were given regarding the process for managing elk populations. As a hunter, I left with the impression that both elk and bison numbers could be managed by quota hunting opportunities. I had that impression more for bison than elk though.
We also saw mule deer, coyotes, black bears, moose, and a single wolf while in the park. It was a great trip.
