The results of our study the ontogenetic structure cenopopulations woody plants on 16 permanent sample plots in mature pine forests located Moscow are presented. For first time, a cenopopulation approach was used to assess regenerative capacity tree species dendrocenoses conditions region. examined areas stands which representative spectra considered, namely: Pinus sylvestris L., Acer platonoides Tilia cordata Mill., Ulmus laevis Pall., Corulys avellana L. Analysis number trees and shrubs lower tiers (undergrowth understory) their occurrence carried out. P. has right-sided age spectrum with predominance individuals generative state is regressive under these conditions, since pregenerative completely absent. A. , U. C. characterized as effectively self-sustaining, while T. moderately selfsustaining. Based study, most populations studied were established be incomplete due absence certain states plants. A significant part have bimodal spectrum. formation generation cycles broad-leaved explained by presence sufficient open – “gaps”. It noted that young fairly mortality rate before they reach influence external intracoenotic factors. composition undergrowth understory showed set shrub vegetation included 12 species.
