The comparison between subrecent pollen spectra and plant macrofossil complexes with the taxonomic diversity of tundra vegetation was makes by methods of comparative floristic on example of Yuribey River on the Yamal Peninsula. The results of analyses are showed that subrecent materials by the composition corresponded to the present tundra vegetation type. They include representatives of the leading families and taxons from coenotic active fraction of flora. In a small number in the subrecent materials contains long-distance transported component presented by pollen and seeds of trees (Betula sect. Betula, Picea, Larix).
