Comparative analysis of the lawns structure along Belgrade city roads

Abstract

The research includes a comparative analysis of the structure and floristic composition of different types of lawns along Belgrade roads (grass areas of roundabouts, dividing strips, areas near roads and grass areas of first order roads), their floristic composition, as well as determining changes over a period of 17 years. The analyses are based on the results of floristic research from 2002, as well as the results of field research conducted during 2019. A total of 114 plant species were recorded on the studied lawns along Belgrade roads, among which the highest proportion belongs to the category of weed species. The taxonomic analysis has shown a reduction in the recorded number of families and genera over the study period of 17 years Both studies indicate the absolute dominance of plants from the group of hemicryptophytes. The results of the research are used to provide guidelines and recommendations for improving the condition and structure of lawns along Belgrade roads. Also, they provide the basis for the future selection of adequate types of grass for the establishment of new lawns, as well as the repair of the existing ones, i.e. for the sustainable management of green spaces along city roads.
