| Popis | Only little is still known about the presence and distribution of different bat species in the province of Flemish Brabant (Flanders, Belgium). From 2012 till 2014, several research methods were combined to collect data about different species. The fieldwork especially focused on four of them : Nyctalus leisleri, Myotis emarginatus, Myotis myotis and Myotis bechsteinii. Twenty forests and parks, well distributed over the whole province, were investigated with bat detectors. This resulted in 2706 recordings from 14 different bat species, with most abundant Pipistrellus pipistrellus (1716, 63,3%). Netting with the use of an acoustic lure was conducted in forested areas, resulting in 264 caught bats from 11 species. For finding Myotis emarginatus, automatic detectors were placed in stables and barns. In a stable where the presence of M. emarginatus was proved, netting was conducted. Caught individuals were tracked, telemetry revealed a small roost, routes and foraging areas. Additional to the yearly monitored hibernating sites (mainly ice cellars and bunkers), permission was granted to count hibernating bats in two larger military sites – fort Leopold and the Citadel of Diest. With seven different species, both sites appeared to be regionally important for hibernating bats. Mistnetting on swarming bats at those two sites and a tunnel in the large Sonien forest, resulted in 10 bat species – including Myotis emarginatus and M. bechsteinii. With M. myotis as target species, 50 attics from churches and abbeys around larger old forests were checked on the presence of bats. Even though M. myotis could not be found, 42 attics hosted other bat species. Visual observations, carcasses and DNA extraction from collected bat droppings showed that it concerned here at least six species ,mostly Plecotus austriacus and P. auritus. The use of the different research methods, manual bat detectors, automatic bat detectors, mistnetting with lure in forests, mistnetting in stables, telemetry, winter countings, swarming research, attic investigations and DNA analyses, provides complementary information about the presence and distribution of 15 bat species in the province. |
