Between 1958-2000, 3,148 records of hibernating bats were made in a natural limestone cave, 92 % of them concerning Rhinolophus hipposideros. Other species included Myotis myotis, M. mystacinus, M. brandtii, M. emarginatus, M. nattereri, M. daubentonii, Plecotus auritus, P. austriacus, and Myotis blythii. The abundance of R. hipposideros decreased between 1958-1963 and between 1970-1974. The number of bats increased between 1984-2000 due to the protection of the cave. Between 1991-2000, 517 bats were netted and banded from spring until autumn in front of the cave. Nettings of species not found in winter (Myotis bechsteinii, Eptesicus serotinus, Vespertilio murinus, Nyctalus noctula and Barbastella barbastellus) increased the total number of species to 15. Significant differences were found in species composition, diversity and dominance between the netted and hibernating bats. We analysed 1,038 individuals marked at Turold and 237 recaptured, plus 10 bats marked elsewhere and recaptured at Turold. The longest movement recorded (66 km) was in a female of M. blythii, the highest age (19.5 years) was in a male of R. hipposideros.
