Objective – to set changes in the composition structure of the Monumental glade of state dendropark Trostjanets of the NAS of Ukraine for the last 60 and to give the estimation of her modern state. Material and methods. An object of researches – landscape elements of the Monumental glade (decorative arboreal groups, copsy, single trees, edge of a forest). The changes of composition structure of the Monumental glade determined by comparison of the data driven to the publications of I.N. Gegelskiy (1958) and I.A. Kosarevskiy (1964) with the data got by us in 2017–2018. Determined change in quality and quantitative floristic composition of decorative registration of glade and her bordering, in configuration of both separate decorative groups and open-space and glade on the whole, in the system of prospects and road-net. For this purpose in 2017–2018 taking of inventory of planting of glade is conducted, measurements of separate decorative groups and lateral branches are produced. Results. For the last many trees fell out 60, that resulted in the noticeable rarity of both base-line arrays and decorative groups or to their complete destruction and to the changes in configuration and sizes of glade. The system of prospects of glade was formed by the division of her spacious territory and different geometrical form copsy by arboreal groups and separate trees on more shallow areas. The landscape of glade are organically tied up with arboreal groups and arrays that is located outside a glade and, bordering her, also participate in the construction of prospects. Certain changes happened in the system of prospects of the Monumental glade: the area of free space increased notedly; a glade became more transparent and exposed, that increased the exit of many prospects after her. Conclusions. Both the analysis of dynamics of specific composition of the landscape planting tetifies, in time in him there are substantial changes both on natural reason (age-old aspects, interspecific competition, individual features of plants etc.) and because of anthropogenic influence. Principal reason of noticeable of the exotic trees used for decorative registration of the Monumental glade is an achievement by them the age-related border in the conditions of dendrology park. For maintenance of high-decorativeness of planting realization of the permanent monitoring of their state and change of orientation of transformation changes are needed toward a improvement. To that end it is necessary constantly to conduct the certain complex of optimization measures. Renewal of decorative groups of glade is impossible without moving away of local kinds that took the place of exotic plants. Realization of deckhouses of care limits now.
