Résumé :	The Mandarin Duck became established in Germany as a neozoon during the last century. An outstanding source was Berlin, where releases took place in the 1920s planned by O. Heinroth in the Grosser Tiergarten, the large central park of Berlin near the Zoological Garden. During World War II the development was interrupted. However, as early as in the 1950s the Grosser Tiergarten in Berlin was colonized again. From here, in the 1980s the small population started to spread towards southwest arriving at Potsdam about 1990. The population increase is best documented by winter counts, which exceeded 400 individuals. Knowledge from other parts of Germany is summarized, and, although more or less incomplete, yields an estimate of 250-370 breeding pairs in Germany. The ecological position of Mandarin Duck causes no real competition with other species. Any actions to reduce the population for reasons of nature conservation cannot be recommended.
