Dynamics of some rare species of plants on excessly moistened plants of vegetation of the Moscow region

The article provides materials on a number of protected plant species in Moscow and the Moscow region, growing in over-wetted areas of forest, damp glades and in swamps. For a number of plants, long-term observations of the dynamics of their numbers are carried out. The connection of fluctuations in the abundance of a number of plants with weather conditions, primarily the amount of precipitation during the summer period, has been established. Moneses uniflora was found in excessively moist areas of middle-aged pine and birch forests with an admixture of alder gummy. The main satellites of the same flower are Ramischia secunda, Carex caespitosa. In 2007, Moneses met in numerous groups. After dry 2010, a sharp decline in its numbers began, in 2018 only a few specimens were found. On the territory of Moscow, Equisetum variegatum is marked on the Shchukinsky peninsula in a wet middle-aged birch forest with an admixture of pine. Its main satellites are Lycopus europaeus, Phragmites australis, Pyrola minor, Carex hirta...
