During 264 controls 8,680 bats were found, of which 8,652 were identified. Sixty-four caves were controlled at least once, and bats were found in 56 of them. The presence of at least 13 bat species was confirmed: Rhinolophus hipposideros, R. ferrumequinum, Myotis myotis, M. bechsteinii, M. nattereri, M. emarginatus, M. mystacinus/brandtii/alcathoe, M. dasycneme, M. daubentonii, Eptesicus nilssonii, E. serotinus, Plecotus auritus and Barbastella barbastellus. The most numerous species were R. hipposideros (71.6%), M. myotis (13.5%), M. emarginatus (6.8%), and B. barbastellus (4.2%). Over the past 35 years 
a distinct increase in the numbers of bats has been observed. The biggest increases concern R. hipposideros, M. emarginatus and B. barbastellus. After an increase from 2013 to 2017, the population of M. myotis remained stable during the next five years of research. The rare bat species R. ferrumequinum, M. bechsteinii, and E. nilssonii were noted. The most important sites are: Ciemna Cave, Nietoperzowa Cave, Racławicka Cave, Twarda Cave, Wierzchowska Górna Cave and Łokietka Cave.
