The territory of the Botanic Garden of P. J. Šafárik University creates suitable conditions for a wide range of wild species of animals. Over 100 species of birds, 25 species of mammals, 8 species of amphibians, and 3 species of reptiles have been found in the previous observations in this area. Interim monitoring results also point to an interesting invertebrate fauna. For example, we register over 40 species of ants representing more than a third of the species of the myrmeco fauna in Slovakia, which is remarkable in such a relatively small area. The ongoing inventory of other groups will certainly bring interesting results.
Heated greenhouses are a specific environment in which several exotic thermophilic species of animals have found their suitable milieu. In addition to phytophagous species damaging plants and species deliberately released against them as a part of biological protection, other species also occur spontaneously.
