Palaeoecological investigations of buried peat profiles from the Zbudovská blata marshes, Southern Bohemia

Abstracts

The authors present the results of basic stratigraphic investigation, pollen analyses and macroscopic analyses of plant remains concerning two buried peat profiles and their mineral covers in the Zbudovská blata marshes near České Budějovice (southern Bohemia, Czechoslovakia). Both profiles (JC-9-A and JC-9-B) are characterized by two phases of sedimentation—earlier organogenic (Dryas III, Pre-boreal, Boreal periods) and later minerogenic (Sub-atlantic period). A stratigraphic hiatus appears between these two phases. The palaeoecological investigation supports the existing information about the rare occurrence ofCorylus in some areas of Czechoslovakia during the Boreal period, brings proofs of fir forests in the area of the České Budějovice Basin in the early Sub-atlantic period, and yields new data on the palaeophytogeography of some aquatic, swamp and mire plants. The paper also attempts to reconstruct the succession of local peatforming communities. A comparison of the development of vegetation in the České Budějovice Basin and in the neighbouring Třeboň Basin is appended.
