Bats in Kaunas

The city of Kaunas in Lithuania has eleven bat reserve areas within its city limits, a merit only a few cities can be proud of! These reserves were established in June 1991 to protect Lithuanian bat diversity and to save the main winter roosts of Lithuanian bats.

The reserves are in the area of the former Kaunas fortress built at the end of the 19th century and partly rebuilt at the beginning of this century by the Russians. In the meantime, people have moved away from the fortress and today the humid and cool vaults and corridors provide a perfect place for hibernating bats. To ensure the safety of bats hibernating there, thereserves are fully closed from September to May. Naturally it is forbidden to destroy roosts and the habitats of protected bats, and penalties for such foolish action are in force.

The Lithuanian bat fauna includes over 10 species. The most abundant species are Myotis daubentoni, Pipistrellus nathusi, Plecotus auritus and Eptesicus serotinus. As in many parts of the world, Lithuanian bats have also declined in recent years. Although historical information in scarce, it is clear that Lithuanian bats are under threat and many species are today less common than formerly.
