There are collections of invertebrates and vertebrates, unique plants and animals and rare species included to the Red book. The museum exposition begins with the geographical location of Roztochia. Then one can see stands with local rocks and minerals, lichens and mossies, fruits and seeds, pathogenous fungi. In jars with formalin a fish, an adder and a grass snake "swim", and on the opposite side one can see the local flowers "in blossom".
The museum collection of stuffed animals is of great interest — one can see a deer, a badger, a wild boar.
