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.
Often, one of the adult wolves stays with the pups to watch over them. Wolf pups love to play. They chase each other and roll around the way dog puppies do. Many of their games appear to be a sort of practice for the things they will do as adult wolves.Pups have been observed playing with toys like bones, feathers or the skins of dead animals.his sounds terrible to us, but wolf pups love it! All the wolves in a pack help take care of the pups. When the pups are very small, other pack members bring food to the mother so she does not have to leave the den.
