Monitoring Bat Colonies in the Mines of Furceni and Morovaia, Near the "Orheiul Vechi" Cultural-Natural Reserve
The study of rock-dwelling fauna continues to yield essential insights into local biodiversity. Recent monitoring efforts have centered on maternity colonies within the Furceni mine while expanding for the first time to abandoned mines near the village of Morovaia, close to Orheiul Vechi. These findings underscore the critical role that subterranean habitats play in sustaining protected bat populations. The research was conducted as part of the project "Protection of Rare Fauna Species and Regulation of Tourism in the Rocky Habitats of the Orheiul Vechi Cultural-Natural Reserve".
Over the summer, fieldwork at the Furceni mines homed in on a maternity colony of lesser horseshoe bats numbering around 700 expectant females.
Listed in the Red Book of the Republic of Moldova, the lesser Horseshoe Bat (Rhinolophus hipposideros) is the genus's tiniest representative, tipping the scales at just 3 to 9 grams. This cave-dwelling mammal relies on subterranean hideouts for both hibernation and breeding. While scattered across the country's wooded areas, it thrives in higher numbers along the rocky river valleys of the Dniester, Prut, and their tributaries. After mating in the autumn, females split off from the males to form dedicated maternity colonies through pregnancy, birth, and nursing, eventually producing a single pup. Hibernation runs from November through March. Their menu features a steady diet of flies, moths, small beetles, and the occasional spider.
As a bonus finding, researchers spotted three Barn Swallow (Hirundo rustica) nests tucked away inside the mine.
Finding swallow nests deep underground highlights how flexibly the species can adapt to subterranean settings, making the most of available rock structures to safely raise their young..
Morovaia Gorge Mines
For the first time this year, surveys were carried out in the abandoned mines near the village of Morovaia, close to Orheiul Vechi. These subterranean hideouts turned out to be home to an array of rare bat species, including the lesser mouse-eared bat (Myotis blythii), Natterer's bat (Myotis nattereri), the grey long-eared bat (Plecotus austriacus), the whiskered bat (Myotis mystacinus), and Bechstein's bat (Myotis bechsteinii).
Every species found on-site is listed in the Red Book of Moldova, with Bechstein's bat and Natterer's bat flagged as critically endangered.
