Wolves are definently gonna be a big problem for the elk populations. Not only are they some of the most wasteful and cruel predetors the absence of the wolves for so long has had the elk and other game animals forget how to protect themselves and survive with wolves. They have become an unhealthy and unethical change to the game populations in most of the areas of reintroduction. Ive got a poll on what people think the effect of the reintroduction will do to the Northern Yellowstone elk herds on my site at www.freewebs.com/smokechaser if anyone wants to vote on it.
