According to the results of the research on phytomagnification of the connecting territories of the ecological network of Vinnytsia region, the distribution of rare and endangered species of higher vascular plants, which characterize the value of these territories, is determined. An ontogenetic-populational analysis of the state of cenopopulations was carried out on an example of the rare species Lilium martagon L. This species is a model for the studied phytocoenoses of the connecting territories of ecocorridors of the national (South-Bug, Dnestrovsky), regional (Lyadovsky, Nemiisky) levels. The ontogenetic spectra of investigated L. martagon L. populations were constructed and analyzed for their belonging to one of four types: left-sided, centered, right-handed, bimodal. It is determined that they belong to incomplete ones, with the prevalence of the right-hand spectrum. The integral estimation of the population condition is carried out using the ontogenetic indices of I. M. Kovalenko (indices of regeneration, aging, generative and age). The index of age-old AA Uranov - Δ, index of efficiency of L.V. Zhivotovsky - ω is calculated. The affiliation of each of the studied populations to a certain type of ontogenetic structure of populations according to the classifications by TA O. Rabotnova (invasive, normal, regressive) and LV Zhivotovsky (young, transitional, dying, mature, aging, old) are determined. According to the results of the conducted research, it has been established that L. martagon L. populations are characterized as normal with subsequent transformation into regression. On the basis of the obtained results, conclusions are made on the ontogenetic structure of model populations of the rare species L. martagon L Author Biographies Vira Shavrina, Institute of Agroecology and Environmental Management of The National Academy of Agrarian Sciences of Ukraine Metrolohichna str., 12, Kyiv, Ukraine, 03143 Researcher Department of Landscapes, Biodiversity and Nature Reserve Laboratory of Ecosystem Biodiversity
