The significant changes in vegetation composition during the Holocene can be traced by pollen delivered into sedimentary archives, such as bogs and lakes. They are ideal archives for investigating these changes, as pollen usually is well preserved in lake and bog sediments and can be used as proxy data for vegetation reconstructions. Earlier palaeoenvironmental studies were mainly based on pollen percentages and did not reflect pollen-vegetation relationships. Therefore, the REVEALS (Regional Estimates of Vegetation Abundance from Large Sites) model was applied to obtain quantitative reconstruction of the past vegetation composition for the north eastern area of Latvia. The results of REVEALS modelling are compared with previous reconstructions.
