The article is devoted to the study of the dimensional and space-time structure of Caragana arborescens Lam. in various ecological and cenotic conditions in the forest park named after. Foresters of Russia in Yekaterinburg on the basis of population and organismal parameters. For the first time, a quantitative characteristic of the manifestation of organismal indicators in each ontogenetic state of the caragana was obtained. Regularities in the manifestation of traits depending on the ontogenetic conditions of plants and forest type, as well as features of changes in traits that occur during the growth of individuals during the life period, are revealed. Features of the average values of the manifestation of traits in ontogenetic states can be associated with the number of individuals of a given state in the corresponding samples, while there is an influence of habitat conditions. A one-way analysis of variance, in which the habitat type of a coenopopulation fragment was a factor, showed a significant effect of the factor for traits of crown height and width. Significant differences in these traits of the habitat of the mixed herb meadow from other habitats and the reduced values of the traits in the forb pine forest are explained by the predominance of medium generative individuals in the first case, and juvenile individuals in the second. The ability of the species to successfully adapt in fragmented and urbanized areas affected by recreational impacts and other forms of pollution and survive in a wide range of environmental conditions has been established.
