Scientific research has left no doubt in his mind about the beneficial - really, ecosystem-saving - presence of wolves.

So Mary and I jumped at the chance to assist this professor emeritus at Oregon State University in his field work related to plants, elk, and wolves. His scientific wandering takes him well off trail in areas of Yellowstone where grizzlies travel. Adding two people, even if they aren't scientists, to his group of one makes sense.

As we walk away from the trailhead and toward the distant hills where we will spend the day working, Beschta points with his hiking pole to some healthy willows and aspen growing along Glen Creek. If wolves were still absent from Yellowstone, he says, those aspen and willow would have been eaten down to the nubs by elk who could dine there for as long as they pleased.
