- Аннотация: Original and literary data on demographic structure of tree populations in disturbed and undisturbed forests are colligated. Capabilities of ontogenetic methods for estimation and prognosis of forest successions are shown on an example of forest communities of Eastern Europe.The brief generalized diagnoses of ontogenetic stages of trees are presented with marking of forest layer where one can find individuals in correspond ontogenetic stages. Estimation algorithm of coenopopulation status is described on a base of ontogenetic analysis of a tree population. Estimation algorithm of succession status of a plant community is described on a base of compared analysis of status of tree species populations. Definitions of climax and succession are presented on a base of concepts of population structure of live cover of the Earth. Uneven-aged forest with developed mosaics of gaps in canopy and tree falls is considered as a final stage of succession. This forest can be defined as climax or diasporic subclimax in depends on number of species from regional flora which occur there. The groups of early and late succession tree species (ESS and LSS respectively) are defined according to species capabilities to settle in disturbed areas and according to species possibilities of sustained existence in climax forest. It is shown, how one can estimate succession status of a plant community by a compared estimation of ESS and LSS populations. It is marked that there is a problem of attributing of uneven-aged forest with LSS to climax, sub-climax or succession forest. Gap and tree-fall mosaics as well as structure of soil vegetation and soil cover are needed to be considered. Estimation of succession stage of a forest plant community can be done not only on a base of ontogenetic data on tree populations, but also on a base of ordinary data on vegetation sample plots and forest inventory. A brief description of methods for such estimations are presented. It is marked that one have to account spatial parameters of a study area for prognosis of succession dynamics of plant communities. Area and neighbourhood of plant communities in different succession stage with different floristic composition are necessary to consider.
