The remarkable part of the forested area is swampy. In certain regions, like the vast West Siberian plain, swamp and waterlogged ecosystems occupy about 30% of the total area. The biogeochemical cycling in these ecosystems is very complex and specific. The slow rates of biogeochemical turnover, typical for all Boreal Forest ecosystems are more depressed in Swamp ecosystems. For instance, in the Sphagnum Swamp ecosystem, the most widespread type of Swamp ecosystems, the annual NPP... 

The plan would have reduced the average annual discharge of the Ob and Yenisey by 32%, created a gigantic 250,000 km reservoir on the West Siberian Plain inundating swamps, forests, farmland, and the largest, but unknown at the time, oil deposits in the USSR.

Little was heard of it after Stalin s death in 1953 when the grand plans for Nature Transformation were quietly shelved.
