International Experts Exchange on Sicista betulina in Molfsee, Germany from 28. - 30. Oct. 2012

The Northern Birchmouse (Sicista betulina) shows a compact distribution east of Finland, the Baltic States, Poland and the Slovak Republic. Additionally there are scattered relict populations in Norway, Sweden, Denmark, Germany and Austria. In contrast to its wide distribution there is a lack of theoretical knowledge and especially practical experiences about the Northern Birchmouse. Thus in practical nature conservation Sicista betulina remains mostly unconsidered. This is a heavy neglect of the species’ relevance in European legislation and of its role as a part of Mammal Biodiversity.


Experts throughout Europe ask the same basic questions:

How can I detect the Northern Birchmouse? What do I have to do to safeguard its populations?

We think, an international exchange about Sicista betulina is an important step to collect and distribute the existing knowlegde and maybe to establish project groups for further cooperations.

We invite You to be a part of the "International Northern Birchmouse Exchange" in Kiel (Germany)!

The meeting has a clear focus on the exchange of practical experiences and the exchange of conservation issues and conservation project ideas!



The “International Birchmouse Exchange” is part of the Danish-German INTERREG-Project “BioGrenzKorr”, which is co-financed by EU funds from the INTERREG 4 A programme.

The Northern Birchmouse situation in the project region can be described as follows:

In the wider Danish-German border region Sicista betulina is present in several sites; first animals were already recorded in 1936. Since then knowledge hasn’t much increased on the German site, while experts in Denmark successfully surveyed this species. There nowadays researchers gained a completely new view of the species’ distribution. On this regional scale knowledge transfer has started, but there is a big need for the exchange of knowledge and practical experiences on a European scale. The INTERREG-partner organisations aim at the exchange of knowledge and as a result of this als work on the improvement of the situation of small mammals which are listed in the Habitat Directives’ Annex IV (S. betulina, M. avellanarius, different bat species).  The “International Experts Exchange on Sicista betulina” is part of this project.
