This report
presents data on the species composition of bats
inhabiting underground structures and complexes
on the left bank of the Dnister River according
to survey results for 2020–2021. Field studies of
bats (order Chiroptera) inhabiting underground shelters
of the left bank of the middle and lower reaches
of the Dnister were conducted from August 2020 to
October 2021. In total, we found 26 underground
sites and complexes potentially suitable for bats
in Transnistria and in 15 of them we counted their
number and species composition. Most of the detected
underground objects are of anthropogenic origin
(former industrial tunnels for limestone mining
and manual mining), and only 2 of natural origin
— a shallow cave in the village of Rascov, Camenca
District and a karst cave in the village of Mikhailovka,
Rybnitsa District. The identified objects formed
the basis of the first detailed cadastre of underground
structures of the left bank of the Dnister and adjacent
areas. Each underground facility was mapped with
exact GPS coordinates and assigned a corresponding
index and serial number. According to the survey
results, 8 species of bats were recorded: Rhinolophus
hipposideros, Myotis blythii, Myotis bechsteinii,
Myotis daubentonii, Myotis dasycneme, Plecotus auritus,
Plecotus austriacus, and Eptesicus serotinus. The
most widespread and frequently encountered species
in the studied area are the lesser horseshoe bat
Rhinolophus hipposideros and Daubenton’s bat Myotis
daubentonii. The rare species include the brown
long-eared bat Plecotus auritus and the grey long-eared
bat Plecotus austriacus. The pond bat Myotis dasycneme
and Bechstein’s bay Myotis bechsteinii are considered
extremely rare, and the latter has never been recorded
in Transnistria before. Based on the obtained data
and in order to preserve the species diversity of
bats, we identified a number of underground complexes
as key objects of primary importance in the life
of bats during hibernation and their breeding season.
