Purpose. Study of the dynamics and ontogenetic condition of Galanthus nivalis L. and Allium ursinum L. in the localities of the National Natural Park «Kremenet’s Mountains». Methods. Field, statistical, analytical. Results. The present state of the localities Galanthus nivalis L. and Allium ursinum L. in the territory of the National Nature Park «Kremenet’s Mountains» was described. Affiliation of each studied populations to a certain category was determined, according to classification of T. O. Rabotnov (invasive, normal, regressive). Ontogenetic spectrum of the localities species were constructed and analyzed in the aspect of their belonging to one of the types: left-side, centered, right-side. Proportion of plants of different ontogenic states in the investigated localities was determined. On the basis of the received results there were made conclusions on the ontogenetic structure of Galanthus nivalis L. and Allium ursinum L. localities in the conditions of the National Nature Park «Kremenet’s Mountains» are made. Conclusions. In the National Nature Park «Kremenet’s Mountains» for Galanthus nivalis L. and Allium ursinum L. there are three periods and six age classes. It was established that most of populations were full nominated of normal type, and are characterized by monomodal, left-sided age spectrum with maximum on individuals of pregenerative period. In the studied localities, there were no sprouts, but the presence of juvenile specimens indicates the fullness of their age spectrum.

Purpose. The study of ecological and biological and environmental features cenotic growth of C. majalis (L.) in terms of forestry suhrudy Kivertsi Volyn region. Methods. Field, biometrics, statistics. Results. Researched environmental growing conditions lily of the valley (Convallaria majalis L.) in conditions sugrudy Kiverzivsky forestry. The characteristic species as one of the dominate species of grass-bush tier. Installed forest floristic composition of plant communities featuring species.Analyzed the «age» and «ontogenetic population structure» on the basis of the determination ontogenetic spectrums and types of populations.Described the impact of lighting on morphometric parameters aerial organs of C. majalis L.: width and length of the leaf blade, the number of flowers and fruits. Conclusions. The sugrudy conditions of population C. majalis (L.) is not complete spectra that belong to normal and invasive types. The light level is not significantly affect the morphometric parameters of the leaf blade, flowering and fruiting, and the state of the population C. majalis (L.) and its development depends, first of all, on the internal rhythms ontogenesis and human impact.
