By its geomorphologic, climate, and vegetation characteristics, Nature Park Papuk provides exceptional natural habitats to numerous animal species. Almost all representatives of middle-European fauna live here. More then 200 years ago, according to the natural scientist Taubea, in the area of Papuk lived bears, wolves, lynxes, and beavers, which died out.

Thick woods of Papuk showed to be an ideal habitat and shelter to numerous wild animals. Their habitats are overlapping, so one can find several animal species in same locations: deer, doe, and boar. From the smaller mammals, there are foxes, badgers, pine martens, even otters, which live in the stream Brzaja. Out of other fauna, in the bushes there are hedgehogs, and moles, but in the ground and trees there are a lot of beetles of the order coleoptera, butterflies, and other insects.

Numerous mountain streams in Papuk are habitats to specific fish species, amphibians, and reptiles. Cold, clear water of streams Brzaje, Kovačice, and Dubočanke, are habitats of autochthon lake trout, which has hatching ground in the upper streams. Besides, one can find fresh-water barbel, and lamprey. From the animals of water habitats, there can be found endangered population of cray-fish, turtles and several species of frogs

A bird kingdom of Nature Park Papuk is rather diverse and rich in, primarily forest birds. It is hard to find a place where you can't hear them singing. Birds, some with their appearance, some with their songs, create special atmosphere to woods of Papuk. The largest representatives among forest birds today are rare birds of prey, out of which with the appearance and behaviour the most prominent is common buzzard. A very beautiful and noticeable forest bird is golden oriole, whose pleasant song revives forests and groves. The king of all singing birds, nightingale, one can find in the valleys covered with forests, and forests, which are on lower altitudes.

Although the diversity of animal species in Papuk is substantial, some species' numbers are endangered. Therefore, not to repeat the story of the Papuk bears, wolves, or lynxes, we need more effective protection, scientific research, and careful management of this area.
