Abstract

The paper presents the new multy-proxy data from the Bolsheberezovskoye mire, the key-section for forest-steppe region in the Upper Don River basin (central part of European Russia), notably, the Kulikovo Battle-fi eld area. According to obtained results the studied area was covered by steppe (middle Atlantic, early Subatlantic) and forest-steppe vegetation (Subboreal, middle and late Subatlantic). Climatic reconstructions have shown that landscape dynamics of the region in the second half of the Holocene were determined by changes in effective moisture. Even small reductions in annual precipitation, accompanied by the rise of summer temperature by 1–3 °С comparing to their present values, were suffi cient to cause a shift from the forest-steppe to typical steppe communities and, probably, higher frequencies of fi res.
