Wolverine
(Gulo gulo) In our country, the wolverine lives in the mountains and the mountain-adjacent forests. The wolverine became a protected species in 1969 when the population was pushed back to the Norrbotten mountains. Today, the population is estimated at a few hundred individuals. The wolverine has a circumpolar distribution, meaning it lives in mountain and tundra areas as well as in the northern parts of the taiga (coniferous forest) in Europe, Asia, and North America. For most of the year, wolverines live alone in large, extensive home ranges. The wolverine digs a den in the snow. The cubs are blind at birth and have white fur. They weigh about 100 grams.
