Ecological role
Wolves are a keystone species. Their return to ecosystems such as Yellowstone National Park changed the behavior of prey animals and helped restore vegetation and river systems in a chain reaction known as a trophic cascade.
Pack structure
Gray wolves live in family packs usually led by a breeding pair and their offspring of different ages. The pack cooperates to hunt large prey such as deer, elk, and moose, and defends a territory that can span hundreds of square kilometers.
