Vegetation and productivity of mire ecosystems in the reserve «Yuganskiy»

Abstract

Over the last four years, biogeocenological studies have been carried out on the territory of the Yuganskiy reserve, that is located in the middle taiga - the most boggy subzone of the taiga of Western Siberia. The vegetation productivity of the main oligotrophic and mesotrophic mire ecosystems of the reserve, which occupy 30-35% of the territory, is estimated. Phytomass stocks vary from 1200 to 3820 g / m2 and constitute from 7 to 36% of the total stocks of plant matter. Pine stand increases phytomass stocks by 60% on the ryam, by 40% on the ridge, by 10% on hummocks of a pool complexes. Production in the ecosystems of ridges and ryams vary from 700 to 1000 g / m2 per year, in hollows - from 650 to 1700 g / m2 per year, the most productive were more waterlogged ecosystems of pool complexes and mesotrophic open bogs.
