Bats have followed the human for centuries. They are threatened by habitat destruction and the increasing loss of their food source, insects. It is therefore all the more important to design and maintain large bat hibernation sites that are suitable for the species.

From October 26 to 28, 2021 the International Bat Conference "Protection of bat populations - threats, problems, practices, solutions" has taken place via ZOOM. The conference has taken place within the Natura Viadrina + project, financially supported by the INTERREG VA Brandenburg - Poland 2014 - 2020 program of the European Union.

We have put together a diverse program where bat experts from different European countries shared their knowledge and experiences about the conservation of large hibernation sites for bats like industrial buildings, bunkers, caves, etc. For example, the hibernacula "Alte Brauerei Frankfurt (Oder)" in Germany and the bunker complex "Nietoperek" in Poland have been presented.

Andreas Streit & Suren Gazaryan - EUROBATS

The International Agreement on the Conservation of Populations of European Bats (EUROBATS) was set up under the Convention on the Conservation of Migratory Species of Wild Animals, which recognises that endangered migratory species can be properly protected only if activities are carried out over the entire migratory range of the species. EUROBATS aims to protect all 51 European bat species through legislation, education, conservation measures and international co-operation with Agreement members and with those who have not yet joined. The Agreement provides a framework of co-operation for the conservation of bats throughout Europe, Northern Africa and the Middle East. The EUROBATS Secretariat was established by the First Session of the Meeting of Parties in 1995. It started working in Bonn, Germany in 1996. Its particular functions are to  exchange information and co-ordinate international research and monitoring initiatives; arrange the Meetings of the Parties and the Advisory and Standing Committee meetings; stimulate proposals for improving the effectiveness of the Agreement, and attract more countries to participate in and join the Agreement; raise public awareness for the bat conservation.
