Overview
The wolverine is a powerful, solitary carnivore known for its strength and fearlessness despite its relatively small size. It can defend kills from much larger predators and travel vast distances in harsh environments. Wolverines are symbols of endurance and resilience in cold ecosystems.

Conservation
Wolverines play an important role in northern ecosystems by scavenging carrion, controlling small prey populations, and recycling nutrients across vast wilderness areas. They are threatened by climate change that reduces deep, persistent snow needed for denning, as well as habitat fragmentation, trapping, and human disturbance. Conservation efforts focus on protecting large connected habitats, limiting disturbance in denning areas, monitoring populations, and addressing climate impacts to help ensure wolverines can survive in a warming world.​
