Ob river floodplain mire
Mires occupy 40% of the Ob river floodplain within the taiga zone. Their forming started about 8 or 9 thousand years ago. Floodplain mires are highly productive ecosystems. Total standing crop is 4.0 or 6.5 t*ha-1. Standing crop of living phytomass takes 50-60% of the total standing crop. The peak o...
