Quantitative reconstruction of vegetation abundance utilising pollen records from Lake Ladoga, Lake Onega, and Lake Lembolovskoye in north-western Russia was conducted using the REVEALS model. Two modelling approaches, integrated with three sets of relative pollen productivities and fall speeds, produced divergent outcomes. The option that most accurately reflected the vegetation composition was selected for further analysis. The comparison of modern vegetation with sub-recent spectra from surface samples in the study region enabled an evaluation of the reliability of the model. © Author(s) 2024.
