The study I linked to said the opposite. You've got George Moonbat and the BBC claiming it's the magic of wolves.
When you're comparing the destructive force of a wildfire to the minor impact of wolves occasionally redirecting ungulate grazing for causing change in vegetative growth, the non-insane person would recognize that fire is more direct and powerful agent.
The 1988 wildfires burned down over a third of Yellowstone and in the middle of the natural regeneration they introduce wolves and then claim the natural result of fire induced regeneration is somehow the result of the magical presence of wolves. It's utter bison scat and propaganda.
I use the term magical, because that's how all the pro wolf nuts talk about them, all breathy spiritualism.
WHo is george Moonbat? Is he an eco-nut?
