    Notes: Die heutigen Wälder, die man in Europa vorfindet, waren nicht immer dort. VOr 22000 Jahren - im Hochglazial - gab es nur im Mittelmeergebiet die klimatischen Voraussetzungen für das Wachstum von Bäumen. Allerdings waren dies meist keine dichten Wälder, sondern Steppen mit einzelnen Baumgruppen. Das bedeutet jedoch, daß die heute in Europa wachasenden Bäume während der letzten 12000 Jahre - also seit dem Ende der letzten Eiszeit - nach Mittel- und Nordeuropa eingewandert sein müssen. Am Beispiel der Waldbäume Eiche (Quercus), Hainbuche (Carpinus), Fichtet (Picea) und Tanne (Abies) soll diese Einwanderung aufgezeigt werden.

    Description: The paper aims at studying the immigration history of Picea and Quercus since the Last Glaciation in Europe. The data are presented in maps showing the geographical distribution patterns of the first traces of the relevant taxa which point to the very beginning of immigration of the various taxa into the sites studied, not by isopollen-maps, but by overlayering-maps. Another set of maps informs about the geographical distribution patterns of the various taxa becoming important components of the vegetation. The ages are given in calibrated 14C years. The immigration maps cover the time from 14000 cal. 14C yr. b. p. till today. It becomes evident that there existed strong differences in time and in space regarding the immigration processes of the taxa studied.The chosen form of visualizing the migration pattern of the taxa studied enabled a discussion based on regional and spatial aspects like direction, ways, time and velocity of immigration, with regard to a palaeoecological interpretation of these processes.
