82-85 autochthonous mammal species are living in Germany today. For 18 of these a special conservational responsibility exists. Nearly the entire range (> 90-100 %) of three taxa (Castor fiber albicus, Microtus bavaricus - if still existing in Germany - and Mus deomsticus helgolandicus) is restricted to Germany exclusively. For these species Germany carries the highest degree of responsibility. For further 12 taxa there is a high degree of responsibility because a major part of their known stock (> 10%) lives in Germany, and Germany is situated in the core area of the species. For populations of the Northern birch mouse (Sicista betulina) and the Alpine shrew (Sorex alpinus) a special responsibility is claimed because isolation in evolutionary significant (ESU) is strongly supposed. For four taxa at the moment no classification is possible due to lack of information, but a special responsibility of Germany seems possible: a genetically distinct Wood mouse (Apodemus spec.) living in Southwest Germany, populations of the Forest dormouse (Dryomys nitedula) because the geographical limits of the subspecies intermedius occuring in Germany are not known, and for a population of the Greater noctule (Nyctalus noctula) hibernating in Schleswig-Holstein and the population of the Harbour porpoise (Phocoena phocoena) in the Baltic Sea there is currently not enough genetic information to classify. Conservation measures for more widespread species for which Germany has a global responsibility should be focussed in areas with large populations of these species because here the greatest amount of genetic diversity can be supposed. For other locally more restricted species (e.g. Northern birch mouse, Alpine shrew or northern populations of Miller's water shrew - Neomys anomalus) there is an urgent need for strictly protection and management of known habitats.
