02. Article pick: A rewildling triumph: wolves help to reverse Yellowstone degradation

When Yellowstone was first established in 1872 there was no legal protection for wildlife in the park. In fact, wolves were over-hunted by park employees as part of a policy of to eliminate all predators. The last was killed in 1926 and for most of the 1900s wolves remained absent. This left elk populations exploding and made for a very unbalanced ecosystem.

This article shares the results of the historical reintroduction of gray wolves into Yellowstone National Park in 1995, and how these carnivorous creatures brought the park back to life.
