“Ecologically, wolves play a very important at the top of the food chain. Now that we’ve had wolves back in Yellowstone, elk are acting more like wild animals than alternative livestock, and we actually have willow and aspens sprouting along streams where they haven’t been able to grow in 70 years because the behavior of elk has changed. As a result of that, before wolf reintroduction there was one beaver lodge in the northern range of Yellowstone, today there’s nine. And that ripple affect goes into the soil, it goes to the stream, it goes to the fish, migrant birds, so wolves have a ripple affect throughout the region.”
