The Verijärv area, South Estonia over the last millennium: A high resolution quantitative land-cover reconstruction based on pollen and historical data

摘要: Integration of palynological proxies with annual lamina counting, C-14, Pb-210, Cs-137 and Am-241 radiometric dating, historical documents old cadastral maps enabled reconstruction changes in the cultural landscape resulting from extensive forest clearance, arable farming slash-and-burn practices South Estonia over last millennium. Changes land-cover were quantitatively reconstructed using Landscape Reconstruction Algorithm (LRA) models. These reconstructions are accordance data century, while for late 19th century time-slice exhibit a considerably more open higher portion cultivated land than that recorded on maps, possible reasons this discrepancy discussed. Taxa represented pollen spectrum values 70%) agrarian activities including agriculture; AD 1870 to 1950, variable openness (70-80%) 1950 2000, modern overgrowing semi-open (<70%) landscape.
