Wolverines are good climbers and often rest in trees.
They are not fast movers, so they do not chase or stalk their prey. They pounce on their prey from rocks or trees. The female has one litter of every two or three years. She digs out a den in a snowdrift, a tree hollow, under the roots of fallen trees, or under rocks. Wolverines can live up to 13 years.
