Threats to Wolverines
Wolverines rely on deep spring snow to rear their young, so they are especially vulnerable to the loss of their alpine habitat due to climate change. One study suggests that wolverines may lose two-thirds of their habitat by the end of the century.
They are also threatened by trapping, habitat loss and fragmentation, and disturbance from winter recreation activities. Given the low numbers of wolverines and the fact they are spread over such a vast area, each of these threats can have a major impact on wolverine recovery.
Male wolverines are typically 30-40% larger than females.
Height: 16 inches (.41m) (males); 14 inches (.36m) at shoulders (females)
Length: 31-44 inches (.8 - 1.1m) (including its bushy tail)
Weight: 25-55 lbs (11-18 kg) (males), 15-30 lbs (7-14 kg) (females). Exceptionally large males can weigh over 70 lbs (31 kg)
Lifespan: 10-12 years.
