How did wolves affect the elk population?

Wolves play a crucial role in regulating elk populations through predation, which helps maintain a balance in the ecosystem. By hunting weaker and older elk, wolves prevent overpopulation and overgrazing, allowing vegetation to regenerate. This, in turn, supports a diverse range of other species and promotes overall ecological health. The reintroduction of wolves in areas like Yellowstone National Park has demonstrated these effects, leading to increased biodiversity and healthier habitats.
