What was the rationale behind introducing wolves to the greater yellowstone ecosystem?

To balance out populations and to control vegetation growth

Explanation:

The reasoning behind introducing wolves to the Greater Yellowstone Ecosystem was to increase the population of wolves there since they were once scattered because of people killing these animals off with the assumption that they were predators and were viewed as dangerous animals.

The wolves play a key role in keeping ecosystems healthy. They help keep deer and elk populations in check, which can benefit many other plant and animal species. The carcasses of their prey also help to redistribute nutrients and provide food for other wildlife species, like grizzly bears and scavengers
