Following the eradication of the gray wolf in Yellowstone National Park in 1926, the population of elk—a primary prey of the gray wolf—exceeded a healthy size for the park’s ecosystem. Elk overpopulation led to overgrazing of areas that a multitude of other animals relied on for food and shelter. As scientists began to see how essential the gray wolf was to the Yellowstone food chain, ecological restoration strategies were employed to reintroduce the gray wolf to the park in 1996. The rebound effect in the park’s natural ecosystem was noticed almost immediately.
