The park is home to many rare mammals such as the Eurasian lynx ("Lynx lynx"), wildcat ("Felis silvestris"), beaver ("Castor fiber"), Eurasian otter ("Lutra lutra"), western barbastelle ("Barbastella barbastellus"), Bechstein's bat ("Myotis bechsteini") and the greater mouse-eared bat ("Myotis myotis"). Also present are red deer, in which two-thirds of the population overwinter in an enclosure, in order to prevent excessive grazing to the land. Even moose have been recorded in the park, from a population in the Lipno Reservoir, Czech Republic.
