The results of studying the ecological and demographic parameters of 10 cenopopulations (CP) of Cypripedium calceolus L. in the subzone of the southern taiga in the Kirov region (Slobodskoy, Afanasievsky, Lebyazhsky districts) are presented. In habitats with C. calceolus, the main background of plant groupings is formed by representatives of boreal and non-morale ecological-cenotic groups. The limiting factors affecting the spread of the species are the illumination and acidity of the soil. The generative-oriented type of the ontogenetic spectrum is predominant. According to the “delta–omega” classification, the studied CPs are represented by aging and transitional types. According to the vital state, most CPs are thriving, with the exception of CP 5, 7. A comprehensive assessment of the state of C. calceolus showed that the populations are in a state “close to threatened” or “dependent on conservation”.
