Known for their fierce resilience, these elusive predators are facing unprecedented threats across North America's mountains.

In the lower 48 United States, the wolverine population has dwindled to an estimated 300 individuals, clinging to fragmented alpine ranges.

Wolverines depend entirely on deep, persistent spring snowpack to build insulated dens and rear their young safely.

As the snowline retreats higher, expanding human infrastructure and winter recreation further divide their rapidly shrinking territories.

Their struggle is a warning sign. When top scavengers lose ground, it signals a deeper imbalance in the broader mountain ecosystem.

This phenomenon, known as the 'climate squeeze,' continuously forces cold-adapted species upward until there is nowhere left to climb.
