Key words: Great Principality of Moscow, Radonezh, palynological analysis, sporo-pollen spectra, medieval economy, reconstructions of the natural environment and human impact, 13th–16th cc.
The article is part of the Radonezh paleolandscape project of the RAS Institute of Archeology, the RF Ministry of Culture Institute of Heritage and the Biology Faculty of the MSU; it compares the palynological data from a series of cross-sections in different parts of the Morozovskoye bog (Sergievoposadsky region of the Moscow oblast) and the cross-sections in the residual plowing horizons of the village of Ivonino (16th c.). The article suggests methods of identifying the zonal and local components in sporo-pollen spectra, and of comparative assessment of the impact of medieval economy on the natural vegetation through recording the pollen from indicator groups. The article reconstructs the natural environment and human impact on one of elevations of the Klin-Dmitrov morainic ridge during the period of internal colonization of the Great Principality of Moscow in the 13th–16th cc.
