Sphagnum ericaceous shrubs, as well as orchids and carnivorous plants. "Sphagnum" and the peat formed from it do not decay readily because of the phenolic compounds embedded in the moss's cell walls. In addition, bogs, like all wetlands, develop anaerobic soil conditions, which produces slower anaerobic decay rather than aerobic microbial action. Peat moss can also acidify its surroundings by taking up cations, such as calcium and magnesium, and releasing hydrogen ions. Under the right conditions, peat can accumulate to a depth of many meters. Different species of "Sphagnum" have different tolerance limits for flooding and pH, so any one peatland
Leningrad Nuclear Power Plant Leningrad Nuclear Power Plant Leningrad Nuclear Power Plant ( ()) is a nuclear power plant located in the town of Sosnovy Bor in Russia's Leningrad Oblast, on the southern shore of the Gulf of Finland, some to the west of the city centre of Saint Petersburg. It consists of four nuclear reactors of the RBMK-1000 type. These reactors are similar to reactors No. 1 and 2 of the Chernobyl Nuclear Power Plant. Two units of the VVER-1200 type are under construction at Power Plant II to replace the current RBMK reactors when they reach the end of their service lives.
