How Wolves Help. Wolves play a very important role in the ecosystems in which they live. Since 1995, when wolves were reintroduced to the American West, research has shown that in many places they have helped revitalize and restore ecosystems. They improve habitat and increase populations of countless species from birds of prey to pronghorn, and even trout.
An arctic wolf doesn't necessarily have predators. They use that for hunting reasons. Their only real enemy/predator is either the human or the bear. The bears are as we all k â¦ now, much bigger than a wolf, and although bears don't eat wolves, they can kill them in a fight.But if it is avoiding enemies (such as the human or bear) they use their white coat to hide in the snow.heir only real enemy/predator is either the human or the bear.
