Vegetation and plant material of the flat palsa peatlands
The aim of the study was to reveal peculiarities and regularities in plant material stock and production as dependent on the plant cover composition, soil characteristics and microrelief of the flat palsa mires in the northern taiga zone in West Siberia. The hollow-lake complexes on permafrost peatl...

Belowground production share in the total production was found to be maximal (70%) in mesotrophic hollows mainly due to the major sedges and cotton grasses. The total primary production was estimated as 4.1 t/ha per year on flat palsa sites, 3.0 t/ha per year in oligotrophic hollows and reached a maximum of 8.5 t/ha per year in dried lake sites.

The aim of the study was to reveal peculiarities and regularities in plant material stock and production as dependent on the plant cover composition, soil characteristics and microrelief of the flat palsa mires in the northern taiga zone in West Siberia. The hollow-lake complexes on permafrost peatlands were chosen as the study sites. The work was carried out in 2013-2017. Plant material structure with differentiation between living and dead belowground organs was investigated and net primary production evaluated. Net primary production was found to range 3.0-4.5 t/ha per year depending on plant species composition of the phytocenosis studied. The production averaged 4.0 t/ha per year with phytomass stock averaging 14.8 t/ha, whereas in dried lake sites the net primary production reached 8.5 t/ha per year with phytomass stock estimated as 18.0 t/ha.
