The pollen production of local taxa is very low, among which Betula nana, Salix, Selaginella selaginoides, Dryas octopetala and steppe xerophytes Eurotia ceratoides, Ephedra and halophilous taxa Kochia prostrata, Salsola kali and Salicornia herbaceae have been identified (Pirrus 1971).
Dryas octopetala leaves from sandy silt at a core depth of 650-645 cm and macro-remains at a depth of 630-625 cm, respectively, showed the ages of 14 370 [+ or -] 205 and 14 245 [+ or -] 155 cal yr BP (Table 2).
Arctic species such as Dryas octopetala and Betula nana almost disappear above this level and the macrofossil assemblage is dominated by aquatic and telmatic plant remains (Potamogetonaceae, Ranunculus sect.
The main species found, Betula nana and Dryas octopetala, are typical pioneer plant species of the late glacial period, which provide information about the local terrestrial biota, suggesting rather severe climate conditions up to 13 500 cal yr BP (660-556 cm).
Arctic species, which are characteristic of late glacial vegetation, were represented by Dryas octopetala, Salix polaris, and Betula nana.
In the lower part of the interval the number of Dryas octopetala leaves reaches a maximum, suggesting a more severe local climate.
