Figure S6. Diagram of main pollen types from core KHQ-14. Microfossil data are subdivided into four phases. Pollen is calculated as percentages of a total land pollen sum including trees, shrubs and terrestrial herbs, but not aquatic herbs or pteridophyte and bryophyte spores. Aquatic herbs, fens, NPPs, microscopic charcoal fragments and foraminifera linings were expressed in concentration form. Calibrated ages are shown by arrows together with age-axis and core column on the left of the pollen diagram.
