In canada they have been allowed to grow and adapt with the environment and the environment with the wolves. This has happened in certain locales in the lower 48 as well. But introducing wolves has been an ecological disaster in most of the West. They aren't allowed to managed, hunted and controlled.
Dropping off wolves into a area rich with game is like giving the town drunk the keys to the bar.
I was not a advocate of reintroduction of wolves due to no plan to limit their numbers and we still don't!
