Abstract: 

The vitality structure of cenopulations of woody plants is formed under the influence of ecological, cenotic and anthropogenic influences. The study of the nature and degree of influence of the ecological parameters of the habitat will make it possible to predict the formation of the vitality structure of woody plants. The objects of study are individuals of the generative age state of three species of woody plants: Quercus robur, Tilia cordata, Acer platanoides. Environmental conditions of habitat were assessed by using range ecological scales. Vitality was assessed by three key determinative morphometric parameters. Correlation analysis was carried out to establish the impact of environmental conditions on the indicators of the vitality of cenopopulations. Both direct and inverse relationships (with a correlation coefficient of 0.5 and above) between ecological conditions and vitality of the studied species were noted. The vitality of Tilia cordata is more influenced compared to other studied species.
