Lawns of urban areas are enriched over time by species occurring spontaneously. To determine the diversity of the lawns, phytosociological studies have been performed. They have shown significant differences. The lawns were distinguished into three groups: settlement lawns, street lawns and park lawns – each group having different species composition. Almost 224 species have been found in the ground cover, 53 in the settlement lawns, 190 in the street lawns and 105 in the parks. Despite the difficulties with the assigning the lawns to phytosociological units, nine synanthropic communities and trampled turf have been distinguished. Differentiation of lawn turf is dependent on the habitat, the area occupied and human interaction. On the other hand, large variation is beneficial ecologically and aesthetically.
