Vegetation history in the Lake Ilchir basin (East Sayan Mountains) for the last 8500 years

The pollen record presented here is the first continuous and well-dated records from Lake Ilchir covering the last 8490 cal years, allowing detailed reconstruction of vegetation and environmental dynamics in the region. The results of the pollen analysis and pollen-based vegetation and climate reconstruction suggest that grass-dominated meadow communities prevailed in the lake basin from 8490 to 6000 kyr BP. The absence of larch and fir stomata in the sediments suggests the growth of trees rather far from the Lake shore. Probably, the climate in the basin was moderately cold with insufficient moisture. The high Scots pine pollen percentage in comparison with surface pollen spectra suggests a higher than today position of the upper boundary of the pine in response of higher-than-present summer insolation. Between 6000-3700 kyr BP the climate was characterized by warmer than modern winter seasons and high snow cover, which did not allow the soils to freeze and supported the development of fir in the Ilchir Lake basin. However, the increased abundance of larch pollen and stomatal cells of its needles in sediments suggest an increased role of larch in the composition of local vegetation and / or its approach to the lake shoreline. Expansion of the areas of larch means that climate gradually became sharply continental, more arid. The last 3700 years was characterized by a continuing increase in climate continentality and cooling that led to the complete disappearance of fir and appearance of spruce in the lake catchment. The more detailed temporal resolution of future palaeoecological records from this region will improve our understanding of the interaction of the lakes hydrology with climate and will provide valuable information for the efficient use of water resources.
