Productivity of mire complexes of Western Siberian cryolithozone

New quantitative characteristics of ecosystem productivity in mire complexes of the Western Siberian cryolithozone are obtained. Standing crop of living above-ground and below-ground phytomass (up to 30-sm depth) in palsa complexes varied from 130 to 230 t · ha-1. Mortmass stock contributes 70% of the total plant mass. Primary production of palsa complexes in the region is about 5 t · ha-1 · year-1, that is two times lower in comparison with the production of ombrothrophic bogs in the middle taiga sobzone of Western Siberia.
