Ontogenetic structure and condition of cenopopulations of Gymnadenia conopsea (L.) R. Br. in plant communities of the taiga zone (Kirov region)

The article assesses the state of the cenopopulations of Gymnadenia conopsea (L.) R. Br. in the plant communities of the taiga zone of the Kirov region. The research was carried out during the 2021 growing season within the Slobodsky and Kirovo-Chepetsky districts of the Kirov region. It is established that within the considered fragment of the range, the studied species grows in meadow, forest communities and forest-meadow ecotonic biotopes. The coverage of the grass-shrub layer varies widely - from 25 to 99%. Total in the studied habitats with G. conopsea 110 species have been identified, the species diversity of the grass-shrub layer of the studied cenopopulations ranges from 14 to 38 species of vascular plants. Vascular plants belonging to 6 ecological-cenotic groups were noted in the composition of the communities under consideration. Meadow and meadow-fringe species are the most widely represented - from 42,1 to 69,0%, and there are many boreal species from 9,5 to 36,8%, which is due to successional changes that are currently occurring in the studied territories and represent a change of meadow community to forest. There are also non-moral, nitrophilic wetland species, and boreal species in small quantities. It is revealed that the generative-oriented type of the ontogenetic spectrum is predominant in the studied cenopopulations G. conopsea . According to the "delta-omega" classification, the studied cenopopulations are represented by an aging type. Based on the results of a comprehensive assessment of the state of the organism and population characteristics, the studied coenopopulations of G. conopsea are in a state "close to threatened", "dependent on conservation" or "causing the least concern".
