Die spät- und frühpostglaziale Vegetationsentwicklung im Umkreis der Alpen. Bemerkungen zur Arbeit von H. Zoller: „Pollenanalystische Untersuchungen zur Vegetationsgeschichte der insurbischen Schweiz“, 1960

Abstract. Based upon newer papers a brief summary is given on Late-glacial and Pre-boreal vegetational history at the western and northern border of the Alps; the effects of the Bölling- and especially the Alleröd-oscillation are demonstrated. Proceeding of that the different results by H. Zoller (I960) in Southern Switzerland are examined and the arguments for another dating of his two Late-glacial pollen diagramms are discussed. According to that the first afforestation in the lowlands at the southern border of the Alps occured not in the Allerod but already in the Boiling period; the „Piottino-oscillation", associated with the Gschnitz-Stadium, is probably not a new discovered Pre-boreal climatic oscillation, but corresponds to the Alleröd-oscillation. Therefore it seems not necessary to doubt the synchronism of Younger Dryas and Schlußvereisung in the Alps.
