The time-series are 10–16 years long, all ending in 2007. We calculated correlations between pollen data and climate. Summer warmth was found to enhance the following year’s PAR of Picea, Pinus non-cembra, Larix and Fagus. Cool summers, in contrast, increase the PAR of Abies, Alnus viridis and Gramineae in the following year, while wet summers promote PAR of Quercus and Gramineae. Wetness and warmth in general were found to enhance PAR of Salix. Care is advised when extrapolating our results to PAR in pollen sequences., because there are large errors associated with PAR from sediments, due to the effects of taphonomy and sedimentation and high uncertainty in dating.
