the method regional populations utilized this greenery was examined. This is done by the combination of archaeobotanical analyses of samples from historical sites and palaeoecological analyses of modern natural deposits. The primary approaches utilized are pollen, wood and charcoal analysis however likewise results from other analyses such as loss-on-ignition, the research study of seeds and fruits, mosses, diatoms, animal bones and molluscs are utilized in this research study.
5700 and 4630 cal BC as an effect of the postglacial relative sea level (RSL) rise, leading to the deposition of wood peat. From c. 4600 cal BC onwards, (peaty) clay was deposited on top of this peat. This clay contains lots of marine and brackish microfossils suggesting tidal activity and a boost of salinity.
3800 cal BC and peat growth resumed. Sedges (Cyperaceae), ferns (Filicales) and birch (Betula) have now become crucial in the wetland plants showing more mesotrophic conditions. In between c. 3840 and 1830 cal BC also yew (Taxus baccata) takes place in this carr vegetation. Additional Info of the mire plants and the combined impacts of a decrease in the rate of RSL rise and a shift to a wetter, more oceanic environment ultimately led to the advancement of oligotrophic bogs.
