Abstract
The paper presents the results of Cypripedium macranthon Sw. monitoring on Bering Island (Kamchatka Krai) in 20122018. Cypripedium macranthon Sw is a rare Orchidaceae species enlisted in several regional Red Books and the Red Book of the Russian Federation. The species on Bering Island inhabits its north-eastern range border and is protected in Komandorsky State Biosphere Nature Reserve. 7 coenopoulations of C. macranthon are found on the island. The studied coenopopulation inhabits the polydominant mixed-herbs-gramineous meadow on coastal sandy dunes. The coenopopulation occupies 4,0 ha and consists of separate loci. The vital state of the plants was defined as normal (3 points). Adult vegetative and generative individuals prevail in the coenopopulation. According to our data the number of shoots was 8 to 16 individuals per sq. m. The average number of generative shoots in 2013, 2017 and 2018 was 9, 10 and 1,4 correspondingly. The maximum generativity index of 81,8% was marked in 2013 due to favorable conditions of the vegetative season. The quantitative data from different periods allow to assume that C. macranthon coenopopulations state is stable which if determined by the population dynamics and proportion of generative shoots.
