| Summary: | Currently population biology and ontogenesis of the species Epipactis palustris remains topical in connection with the protection of the species. The aim is to study the ontogenesis of E. palustris for monitoring and assessment of its coenopopulation in the southern taiga subzone. We studied the cenopopulation of E. palustris which grows within the specially protected area «Nizevsky pinewood». The study was performed using conventional techniques for studying coenopopulations. Ontogenesis was studied on the basis of our own observations, as well as the analysis of literary sources. During the study we have developed our own methodology for the allocation of age states of partial formations of E. palustris, based on the characteristics of leaves and internodes. The age state of partial formations of E. palustris is described. During monitoring the coenopopulation of the species it was found out that the spatial structure has not changed, as for the age range, the changes are minor. Its stability is maintained by means of active vegetative renewal and capture territory, as well as by means of prolonged retention of underground organs. The coenopopulation’s existence is determined by special conditions of the ecotope. Therefore, for the preserving the species and maintaining its stability the full safety of the whole natural ecosystem is required. |
