Current ecological understanding has recognised that ecosystems are subject to ongoing processes of changing climate, disturbances, and many landscapes have been shaped by humans for millennia. Because the fossil data are able to record multiple generations of a species through time, they can be used as a surrogate for measurement of biotic responses to environmental and disturbance scenarios occurring at different temporal scales (10 to 103 years).

Here, I review palaeoecological records spanning the last 60 ka from Central Eastern Europe, with focus on the Carpathian region and tackle several research questions: i) The temporal and spatial magnitude of the vegetation responses to the climate and human impact inferred from pollen records highlighting differences and similarities between sub-regions; ii) Glacial refugia, implication of small localised population survival for postglacial species range shifts and migration rates; iii) Patterns, drivers and consequences of biomass burning in this region and how human-driven fire regimes changed with shifts in land use strategies; and iv) The application of REVEALS model to correct for biases in taxon-specific pollen productivities and dispersal, and basin type for an accurate quantification of vegetation cover and the magnitude and timing of land cover change brought by human use of land.
