European bison

European bison

(Bison bonasus) The European Bison, also known as the Wisent, is a true herd animal. They often move calmly and slowly when searching for food. The herd usually contains 10-30 animals and is led by an older cow with a calf. The European Bison no longer lives in the wild in Sweden. It disappeared from southern Sweden almost 1,000 years ago. The European Bison was exterminated in the wild around the time of World War I, but was saved by the 50 or so animals that were in 8 zoos, one of which was in Sweden. Characteristics of bulls include dark brown fur, a powerful shoulder area, hump, shaggy mane, short broad head with short horns, forelock, and chin beard.

Wolf

Wolf

(Canis lupus) The wolf was one of the first animals to migrate into Sweden after the Ice Age. 150 years ago, it was widespread throughout the country. Through intensive hunting, the wolf was close to extinction during the 1970s and 80s. In 1966, the wolf was protected in Sweden. Since the mid-1980s, the number of wolves has slowly increased, and in the early 2000s, there were about 100 individuals.

Brown Bear

Brown Bear

(Ursus arctos) The brown bear is a forest-dwelling animal, living in the boreal forest areas of northern Europe, Asia, and North America, where it is called the grizzly bear in some areas. The Swedish bear population of a few thousand animals is slowly increasing despite a general hunting of the species. The bear is a plantigrade, meaning that it walks on the whole sole of the foot, just like humans do.

Belongs to: Order Carnivora (carnivores/predators)
Family: Bears (Ursidae).
Weight: Up to 350 kg (males in Sweden), up to 160 kg (females in Sweden).
Lifespan: 20 - 30 years
Mating season: Mating season typically occurs in May-June.
Gestation period: The gestation period for bears is around 7-8 months, but the actual fetal development is only 2-3 months, due to a phenomenon called delayed implantation.
Cubs: 1-3 cubs (sometimes 4 or 5) are usually born in January during the winter hibernation.
