The paper is devoted to reconstruction of natural conditions in the Bronze Age and the Early Iron Age basing on the data of spore-and-pollen analysis with respect to the sediments of Nizhne-Ingalsky-3 settlement. The authors give a detailed description of two sections of the monument, describe their palynological features, give radiocarbon datings, and compare the results with the data obtained from the other sections in the Ingalsky Valley. Basing on analysis of spore-and-pollen diagrams, certain regional features of subboreal and sub-Atlantic periods of Holocene have been discovered.
