An analysis of the composition of surface spore-pollen spectra (SPS) was carried out within a gradient from forest-tundra to northern taiga. In total, 20 sub-recent moss-lichen surface samples were obtained on the territory of the Nadymsky and Purovsky districts of Yamalo-Nenets Autonomous Area. All studied spectra contain pollen of Larix sibirica Ledeb., Picea obovata Ledeb., Pinus sibirica Du Tour, P. sylvestris L., Betula pubescens Ehrh., B. nana L, as well as Ericaceae, Asteraceae and Cyperaceae. In the SPS of the studied communities, an increase in the participation of the pollen of Pinus species, a decrease in the content of Betula nana pollen, and an increase in the diversity of the taxonomic composition of herbs at the transition from the forest-tundra to the northern taiga are observed. The low content of Picea obovata pollen in the forest-tundra and northern taiga spectra reflects the low proportion of spruce in the studied communities. The low pollen proportion of Larix sibirica in the forest-tundra and northern taiga does not reflect the actual participation of L. sibirica in the vegetation cover, but is associated with rapid destruction of pollen and its low flight ability. The low content of Larix sibirica pollen in the forest-tundra and northern taiga does not reflect the actual participation of larch in the stand.
