The article contains a geobotanical analysis of the types of plant communities with the participation of the rare endemic species Rosa potentilliflora Chrshan. et M. Pop. in the Turgen Gorge of the Trans-Ili Alatau. Rosa potentilliflora Chrshan. et M. Pop. It is rare, has a limited range and is endemic to the forest belt of the Turgen Gorge of the Trans-Ili Alatau. Associations of three plant coenopopulations and the percentage of projective design of vegetation cover are described, divided into tiers of plant communities. Within each cenopopulation, a transect measuring 10×10 m2 was laid out and the age composition of Rosa potentilliflora was determined. The development of the population of this species in the forest zone of the Turgen Gorge of the Trans-Ili Alatau is under normal conditions. In all three coenopopulations, the state of fully mature generative individuals was established, starting with seedlings of the Rosa potentilliflora plant.
