Modern pollen data from pristine taiga forest of Pechora-Ilych state nature biosphere reserve (Komi republic, Russia): first results

Abstract

Abstract. The first results of modern pollen investigations from western slop of Ural Mountains presented. 33 modern pollen samples have been collected in June 2016 from four dominant forest types (Sphagnum, true moss, tall fern and tall herbs sections) in Pechora-Ilych state nature biosphere reserve (Komi republic, Russia). The detail record of surrounding vegetation was performed at every sampling point. Pollen assemblages are mostly dominated by tree pollen (Betula type, Pinus haploxylon type and Picea). The pollen assemblages and vegetation records will be statistically analyzed (clustering and correspondence analysis) to investigate how vegetation is reflected in pollen assemblages and for producing new series of PPEs.

Did long‐term fire control the coniferous boreal forest composition of the northern Ural region (Komi Republic, Russia)?

“…The data required for the proper use of REVEALS are the size of the lake/peat, the pollen records and the pollen productivity estimates (PPE). However, the PPE, which is related not only to the species, but also to the region where the species are established, is not available for all regions because it has not been estimated everywhere (Bunting & Hjelle, 2010; von Stedingk, Fyfe, & Allard, 2008; Xu et al., 2014) and has not yet been developed in the Republic of Komi (Lisitsyna, Smirnov, & Aleynikov, 2017). Therefore, the selection of PPE from Estonia was chosen because this site has a forest similar to the one studied in the Republic of Komi and is situated at the same latitude (Poska et al., 2011).…”
