There seems to be a lot of people that think that setting up the proper balance of critters and plants will create an unchanging system. Like the wilderness is a terrarium, or something. We've already seen nature doesn't work that way, it's in a constant state of flux... think fire. There's numerous studies/papers how areas, that have had little or no impact by humans, have evolved in flora and fauna.
To try to sort out what changes are attributable to us, and correct that by restoring this critter, or that plant, is a joke. Wolves interact with a hell of a lot more than Elk, and Elk interact with a hell of a lot more than aspen. It's way more complicated than that, and I'm betting there's a lot of interactions we don't even know about yet.
They're trying to maintain national parks as a static, never changing setting, but that's not nature, that's Disneyland.
