Influence of freezing processes on the vegetation of Sakhalin swamps
Abstract Herewith the current characteristics of the bog vegetation on the Chaivo spit in the north of Sakhalin are outlined. The many-year surveys have discovered icy permafrost at a depth of 45-70 cm which leads to the formation of annual and perennial migratory pingos. Herewith a brief descriptio...

| Summary: | Abstract Herewith the current characteristics of the bog vegetation on the Chaivo spit in the north of Sakhalin are outlined. The many-year surveys have discovered icy permafrost at a depth of 45-70 cm which leads to the formation of annual and perennial migratory pingos. Herewith a brief description of the changes of the pingo vegetation is provided, it has been discovered that the process of lichen growth on the pingos is of selective nature. It has been noticed that some pingos on the bogs of the Chaivo spit have increased in size, which obviously demonstrates the process of replacement, firstly, of mosses by lichens, which in their turn are replaced by herbs and mall shrubs, i.e. pingos on different phases of development can be found. During the period of the surveys, it has been identified that the share of perennial pingos covered with lichens has increased. |
