Lawns occupy a significant share of urban green spaces and play an important sanitary and aesthetic role. Their durability and decorative value are ensured by the use of resilient grass species and well-balanced grass mixtures adapted to specific growing conditions. The study revealed that the most common ruderal plant species found on lawns of various functional types at Uman National University include common dandelion (Taraxacum officinale (L.) Weber ex F.H.Wigg.), ribwort plantain (Plantago lanceolata L.), shepherd’s purse (Capsella bursa-pastoris (L.) Medik.), broadleaf plantain (Plantago major L.), couch grass (Elymus repens (L.) Gould), common yarrow (Achillea millefolium L.), and green foxtail (Setaria viridis (L.) P. Beauv.). In particular, couch grass (Elymus repens (L.) Gould) causes significant damage to lawn stands. It was determined that the level of weed infestation of lawn areas within the university territory is predominantly moderate (3-4 points). Sports lawns were found to be the most heavily infested, where ruderal species occasionally displace cultivated grasses. The study also established that the grass stand structure of ornamental lawns is predominantly closed mosaic, whereas sports lawns exhibit separate-group and mosaic-group patterns, which is attributed to significant anthropogenic pressure. Shoot density in ornamental lawns ranged from 75 to 118 shoots per 100 cm², while in sports lawns it did not exceed 67 shoots per 100 cm². Based on a comprehensive quality assessment, the ornamental lawn located in the parterre area of the university was classified as high quality. In contrast, the quality of sports lawns was assessed as moderate to low, indicating the need for restoration.
