profiles provide insight into postglacial evolution of wetlands related to this landscape. The AA. found clear evidence of the disappearance from the peat of higher vascular species that, today, grows mostly in the plains of Siberia. Correlation of the data
obtained with the accepted chronology of the Holocene events in the Russian Altai suggests the following stages of postglacial environmental change in the Malye Chily River valley : 1) the continuation of the Late Würm glaciation degradation (before 7000
