Species Information
The North American wolverine (Gulo gulo luscus) in the contiguous United States was determined to be a distinct population segment (DPS). This DPS is a candidate for listing under the Act (75 FR 78030; December 14, 2010). The North American wolverine (Gulo gulo luscus) is a member of the Mustelidae (weasel) family and resembles a small bear with a bushy tail. It has a broad, rounded head; short, rounded ears; and small eyes. Each foot has five toes with curved, semi-retractile claws used for digging and climbing. Female wolverines use birthing dens that are excavated in snow. Persistent, stable snow greater than 5 feet deep appears to be a requirement for natal denning as it provides security for offspring and buffers cold winter temperatures. Wolverines occur within a wide variety of alpine, boreal, and arctic habitats, including boreal forests, tundra, and western mountains. Wolverines are opportunistic feeders and consume a variety of foods depending on availability. They primarily scavenge carrion, but also consume small animals and birds, fruits, berries, and insects. Potential threats to the wolverine include climate change, dispersed recreation, transportation corridors, and land management activities.
