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.
Wolves mostly eat mammals or creatures smaller than itsself most like rodents like mica,rats,groundhogs,squirrels and some eat fish like tuna and trout. If you live in countri â¦ es wolfs live in and have a farm they are likely to eat chickens,sheep and lambs aswell. they can also eat bugs of the ground.ray wolves eat deer, elk, moose, caribou, sometimes wild goats, rabbi â¦ ts, mice, other smaller mammals, birds, fish. They have a wide range of prey, including carrion, which is one reason why gray wolves have survived so long. Sometimes they take down livestock.
