For several years, Russian-Kyrgyzstan scientists were actively studying the of Obishir-V site, which is located in Kyrgyzstan. Archaeologists have found that the Fergana Valley and its surrounding territories were actively inhabited by people in the early Holocene, as evidenced by a large number of archaeological sites of that time. They suggest that this process was associated with favorable climatic conditions, the main factors of which were warming and / or increasing humidity. The paper presents the paleoecological results of a study of terrestrial molluscs found in the Upper Neopleistocene – Lower-Middle Holocene sediments of the Obishir-V locality. Taxonomic analysis of the composition of the malacofauna made it possible to reconstruct paleoecological conditions regarding the preferences of the molluscs on temperature, humidity, vegetation and their habitats (biotopes). It was found that paleolandscapes and vegetation remained practically unchanged during the period of accumulation of the studied sediments. Molluscs lived among steppe vegetation in dry and warm climate, but there were also short intervals with higher humidity. Studies have shown that favorable climatic conditions were formed in the region about 13 thousand years ago, three thousand years before the intensive settlement of the territory
