Percentage pollen diagram of selected taxa and categories. Data is plotted on an age scale (cal BP) and tephra layers were excised. Categories: broadleaf deciduous (Quercus deciduous, Corylus, Ulmus, Fagus), steppe (Helianthemum-t, Sanguisorba, Artemisia, Amaranthaceae, Plantago, Apiaceae, Rumex, Galium-t, Filipendula). In the broadleaf deciduous curve, the discontinuous line shows values in Les Palanques core (2 km distance from PdP) and the grey line shows SB2 Banyoles core (25 km away). Sedimentary charcoal data is plotted as accumulation rate of charcoal particles, n of particles > 1 mm width and 0.5–0.99 mm width, and charcoal peaks identified by numerical analyses. Red shadings indicate periods of intense eruptive and fire activity, grey lines show events of tephra deposition. Greenland isotopic curves (GRIP and GISP2)42,43 are plotted and cooling episodes/cold phases (blue) and warmer periods (orange) are indicated.
