“…BMA estimates were calculated with Polygon 1.5 (http://dendro.naruto-u.ac.jp/nakagawa/). The data set of modern analogues consists of 720 modern pollen samples from a wide variety of landscapes in Eastern Europe and Siberia (Novenko et al., ), combined with estimates of forest cover from MODIS satellite images (Hansen et al., ). A test of the accuracy of the applied method using a database of surface pollen assemblages shows that the BMA technique can reproduce present day characteristics with R 2 = .57, SEE = 10.8%.…”

“…Studies focusing on at the structure and position of the Eastern European forest‐steppe ecotone are hitherto not available. However, many palaeoecological studies have been carried out in this region during the last decades (Alexandrovskiy & Chichagova, ; Chendev et al., , ; Khotinsky, ; Klimanov & Serebryannaya, ; Novenko, Eremeeva, & Chepurnaya, ; Novenko, Glasko, & Burova, ; Novenko, Volkova, Glasko, & Zuganova, ; Novenko, Tsyganov, Rudenko, et al., ; Novenko, et al., ; Serebryannaya, ; Spiridonova, ). Although, most of these studies focussed on climate and environmental change at individual sites, not considering the dynamics of the forest‐steppe ecotone.…”

Question The European forest‐steppe ecotone extends over 6,000 km from the Carpathian to the Ural Mountains. It is extensively used for agriculture with very few patches of semi‐natural vegetation. Little is known about the history of the forest‐steppe ecotone in Eastern Europe and here we examine its Holocene dynamics and stability and investigate when it was transformed to the modern agro‐pastoral landscapes. Location Mid‐Russian Upland. Methods We summarize the information from five pollen diagrams for the last 7,000 years and estimate forest cover using the best modern analogue technique. We use the PCA and principal curve analysis to evaluate compositional changes. Results The pollen data suggest that the East European forest‐steppe boundary was located 50–70 km further northwest from the presumed present position during the period 7,000–4,500 cal yr BP. After 4,500 cal year BP, it moved approximately 100–130 km to the southeast. Since 2,000 cal year BP land use affected the boundary, while a total forest clearance and transformation to agricultural landscapes took place in the last 400 years. Pollen data indicate a NW–SE direction of the forest‐steppe vegetation gradient. Prior to clearance, open lime–pedunculate oak forests existed in the NW, while the south was characterized by pine woodlands with an admixture of oak and lime with 20%–40% forest cover. Conclusions The East European forest‐steppe ecotone is sensitive to climate change. The Late Holocene expansion of forest cover is in agreement with evidence suggesting an increase in moisture availability during this time. The rapid recovery to a similar composition after human disturbance indicates a high resilience of woodland in the ecotone, which may be connected to a naturally high disturbance regime, possibly through fire. The information revealed on the position of the gradient and natural composition of the forest is currently not depicted in maps of the potential natural vegetation.

“…The method was recently applied to pollen spectra from Northern Eurasia (e.g., Tarasov et al, 2007 and references therein) and the European part of Russia (Novenko et al, 2014), demonstrating that this technique can be very effective for reconstructing tree cover during the Late Pleistocene and Holocene. The modern tree-cover estimates were taken from the VCF (Vegetation Continuous Fields) product (Hansen et al, 2003).…”

“…The leave-one-out cross-validation test showed the best correlation between pollen-based modern woody cover reconstructions and MODIS measurements at a radius of 20 km (R 2 = 0.5546 and RMSEP = 11.8%), which is sufficient for the reconstruction of major changes in forest vegetation (Novenko et al, 2014). Accordingly, in this study, we used a distance of 20 km as a characteristic radius to reconstruct changes in woody coverage.…”
