In connection with the anthropogenic load on the natural habitats of many medicinal plant species, it is relevant to assess the ecological conditions of growth in order to study the relationships between species and plant communities. The paper presents the analysis of ecological features of some species of the Lily of the valley family (Convallariaceae) in the Kirov Region. To identify the ecological-phytocoenotic association of the studied species in forest communities of the Kirov Region, 45 coenotic populations (CP) ofConvallaria majalis, 10 CP ofPolygonatum odoratumand 20 CP ofMajanthemum bifoliumwere studied. When analyzing the ecological conditions of the species habitats, H.Ellenberg ecological scales were used. Geobotanical descriptions of plant communities were carried out according to generally accepted methods. It has been established that the amplitudes of the ecological spaces of the studied species in the Kirov Region practically do not fit into most ranges of ecological niches calculated on the basis of H.Ellenberg scales. The species have a wide range of adaptability to the studied environmental factors. All studied species are distributed on medium-moist soils (5thlevel of H.Ellenberg scale). The authors have shown that the studied species are similar in environmental factors such as moisture and soil richness with nitrogen.Convallaria majalisandPolygonatum odoratum photophilous species,Majanthemum bifolium shade-tolerant species are distinguished with respect to illumination. In the grass-shrub layer of the studied habitats of the species, 7 rare, small, narrowly araic species are listed in the Red Book of the Kirov Region(Pulsatilia flavescens(Zuccar.) Juz.,Potentilla humifusaWilld. ex Schlecht.,Centaurea sumensisKalen.,Koeleria glauca(Spreng.) DC.,Eryngium planumL.,Geranium sanguineumL.,Carex bohemicaSchreb.). And 4 species that need constant monitoring and observation in the region (Annex 2) Campanula perscifoliaL.,Pulsatilia patens(L.) Mill.,Platanthera bifolia(L.) Rich.,Iris sibiricaL.).
