The park is home to many species of mammal characteristic to northern Sweden, in particular the Eurasian lynx () and the brown bear (), considered endangered in the country. Besides these two species, one can find the red fox (), the European badger (), the European pine marten (), the moose (), the Eurasian beaver (), the grey seal (), and the muskrat (). One can also find small mammals, such as the Eurasian red squirrel (), the American mink () and the stoat (). The territory of the lynx is much more vast than the park itself, which is therefore not sufficient to protect these animals. Indeed, the population of lynx in the region is decreasing, probably because of habitat fragmentation as a result of European route E4.
