Figure 6

Pollen and stomata record of Tăul dintre Brazi plotted against depth and calibrated BP timescales. Norway spruce (Picea abies) fossils are highlighted in red. LPAZ: local pollen assemblage zones as in Table 3; first occurrence of spruce stomata at 13,900 cal yr BP; - early Holocene population expansion of spruce between 11,750 - 10,780 cal yr BP inferred by pollen and stomata increases. Black rectangles along the timescale bar indicate the position of the radiocarbon dated samples.
