What was the rationale behind introducing wolves to the Greater Yellowstone Ecosystem (GYE)?

Wolves were reintroduced to the Greater Yellowstone Ecosystem in 1995 to restore ecological balance and address issues stemming from the decline of the wolf population in the early 20th century. The absence of wolves had led to overpopulation of elk, which in turn caused overgrazing and degradation of vegetation, impacting the entire ecosystem. By reintroducing wolves, wildlife managers aimed to control elk populations, promote biodiversity, and restore natural processes within the ecosystem. This action has since led to positive ecological changes, such as improved vegetation growth and increased populations of other species.
