Abandoned quarries from Saharna 47041rsquo; N, 28057rsquo; E situated at the 80ndash;100 m above the sea level have several entrances. he ceiling consists of multiple cracking, remained after extraction activities and has a height of between 1.5 and 3 m. he irst individuals were observed near the entrance at 2ndash;4 m. A total of 7 km of underground passages were investigated and 325 individuals from 9 species. In 2013 we recorded only 112 individuals from 7 species, while in 2014 ndash; 213 individuals from 9 species. During both years the dominant species was Eptesicus serotinus with about 65% in 2013 and only 40% in 2014, followed by Myotis daubentonii and Rhynolophus hiiposideros in the irst year and by R. hipposideros then M. daubentonii in the second year of study. he rest of the species were registered in low number, between 0.5% and 7%. It must be mentioned the presence of Barbastella barbastellus species with approximately 2% in each study period. It is a very rare, endangered species of our fauna and the Saharna site represent the only known hibernation place of this species in R. Moldova. he abandoned stone quarries from Saharna represent an important bat hibernation shelter, where hundreds of individuals spent the winter and this site need special protection.

Pe parcursul ambilor ani de studiu, specia dominantă a fost E. serotinus cu cca. 65% în 2013 şi 40% în 2014, urmată de M. daubentonii şi R. hipposideros, în primul an de studiu şi de R. hipposideros apoi M. daubentonii, în al doilea an.
