Proctor says returning wolves to Colorado will help restore a predator-prey balance that the ecosystems of the southern Rocky Mountains have not known in a century.

What is one positive ecological benefit that can be achieved by the reintroduction of a native predator?

First, large carnivore reintroduction has to initiate a predictable trophic cascade — that is, where carnivores reduce the abundance of herbivores, which, in turn, increases the abundance of the plants they feed on. Second, the magnitude of that trophic cascade has to push an ecosystem back to a previous state.
