“…The oristic richness of urban areas is closely related to their size (Pyšek 1998 Recent studies have shown that there is still a need for knowledge about global patterns of urban greening in all regions of the world (Bille et al 2023). Urban ora has been extensively studied in most parts of Europe (Pyšek 1998; Celesti-Grapow and Blasi 1998; Loram et al 2008; La Sorte et al 2008; Lososová et al 2011), and these data provide evidence for further conservation and development of urban green spaces (Muratet et al 2008;Čeplová et al 2017).…”

The floristic richness of Bosnia and Herzegovina has long been researched, but little attention has been paid to urban flora until recently, and no systematic surveys of urban ecosystems have been conducted. To address this problem, a study of the urban flora of seven cities in Bosnia and Herzegovina was conducted to determine the pattern of floristic diversity and correlation with anthropogenic factors: Size of the urban area, share of green areas in the total urban area, number of inhabitants and population density. The first finding of the study is that cities in Bosnia and Herzegovina are rich in plant species. Species richness reflects the geographical location, so that cities in the Mediterranean biogeographical region are richer in species, such as Mostar and Blagaj, but at the same time species richness also depends on the total area of the city, as is the case with Sarajevo and Banja Luka. The analyses carried out have shown that the floristic diversity of urban flora in Bosnia and Herzegovina largely reflects the natural vegetation of the urban environment compared to urban flora in other parts of Europe. Moreover, the proportion of alien species is lower and contributes to the heterogenisation of the flora. Among the factors of anthropogenisation, population density correlates most strongly with the richness of urban flora. From the results, we conclude that urban plant diversity correlates with both environmental and anthropogenic factors, but in a way that provides a sound basis for conservation systems in urban ecosystems.

“…While appreciated already in ancient times 7 , urban vegetation is being considered ever more crucial in the context of global urbanisation and growing environmental pressure 8,9 , also in the quest for the Sustainable Development Goal 11 of "making cities inclusive, safe, resilient and sustainable" https: //sdgs.un.org/goals/goal11). Urban vegetation provides a broad range of ecosystem services 10 .…”

Tracking green space along streets of world cities

Street green space (SGS) - the presence of vegetation along streets of cities - is an increasingly relevant indicator for sustainable cities. SGS provides a set of local services such as mitigating the urban heat island effect and reducing the impact of extreme precipitation events, while it is also associated with increasing human well-being. Here we present a global analysis of recent trends in SGS based on modelling a street-based indicator of vegetation density (the Green View Index, GVI) with high-resolution multispectral satellite data and additional granular data. Estimating local to continental trends between 2016-2022 based on 190 large cities distributed across seven macroregions, we find that globally SGS has decreased by almost two percent. Statistically significant changes in city-level median SGS (p<0.01) are found in approximately one-quarter of the cities analysed. However, the direction and magnitude of trends both show a high level of heterogeneity between regions, which we explore by assessing SGS inequalities within each city. Our analysis provides an updated picture of SGS across world cities and an open-source, validated approach to assess its future changes in near real-time and support the design of policies for greener cities.
