Bats in forests

Forest bats roost in different tree cavities or under exfoliating bark. They form nursery colonies there and several species use tree cavities even in winter, during hibernation period.

We have been conducting forest bat research since 1994. Our work extends to the areas of Bükk Mountains, Mátra Mountains, Zemplén Mountains, Heves-Borsodi-Hilly Country, Karancs and Medves Mountains. Observations on forest bats were made on more than 400 nights on 50 different locations.

During our surveys, all of the forest bat species that can be found in Hungary were documented in the research area. The presence of the maternity colonies of all forest bat species were noted.

The colonies of the very rare Greater Noctule (Nyctalus lasiopterus) were localised by radio-tracking.

Unfortunately during the activity of forestry many bats die and/or loose their habitat. The documented data of occurrences can help to find valuable bat habitats and to create conservation plans. In the future we would like to localise forest parts where maternity colonies of strictly protected species are present, and collect data on unexplored forests of the North Hungarian Mountains.
