Green space in an extremely exposed part of the city center “Aorta of Warsaw” - Case study of the urban lawn

The method of developing city centers is the responsibility of local authorities, which must reconcile the interests of investors applying for valuable land with the utility needs and expectations of residents regarding, inter alia, free squares and green enclaves. This study was conducted in Warsaw (Poland). In the study area, for 20 years there has been a discussion about how the area should be developed. So far, the area is used as lawns. During the monitoring period, 72 plant taxa were found. It is possible to state that an urban lawn is an ecosystem with relatively stable conditions, which is, however influenced by human disturbance and specific stress in the city. A city lawn is an oasis of greenery that is easy to set up and maintain, in the case of modernization, it does not generate large costs related to its restoration, unlike gardens. Maintaining an intensive lawn requires not only the selection of appropriate grass species resistant to the influences of the urban environment, but also the optimal way to us it. This research can be used to choose the optimal method for managing and maintaining greenery, considering the conditions of spatial development and environmental factors.
