A section more than 3 m deep from “De Borchert” (near Denekamp, The Netherlands), which included part of the Younger Dryas and almost the whole of the Holocene, was studied by analysing the micro- and macrofossils per 0.8 cm in order to obtain maximum information regarding the regional and local vegetational succession and any climatic changes that might have taken place during that time interval.

Newly recognised and recorded microfossils (fungi, algae, fossils of unknown taxonomic identity) are illustrated, described and interpreted. The analysis of pollen and other palynomorphs in combination with the analysis of macrofossils, permitted the following main conclusions:

During the later part of the Younger Dryas the presence of certain herbaceous forms (e.g., Typha latifolia) indicates a minimum average July temperature of 12–13°C.

A detailed reconstruction of the vegetational and climatic changes …
