Pieniny Mts was the last refuge of the lesser horseshoe bats in Poland, where these bats survived.

In the Pieniny National Park, with kind support of its staff, first Polish research and conservation activities of this species took place, and became the base to create the Lesser Horseshoe Bat Conservation Programme.

The Park safeguarded the horseshoe bat hibernacula and implemented in cooperation with the PTPP “pro Natura”, an experiment to conform the new building of park headquarters to the needs of the bats. As a result, a new horseshoe bat roost have been created.
