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 Bo...

ABstr ACt: 298 endemic taxa at the species and subspecies rank have been found in the territory of Bosnia and Herzegovina (BH Mediterranean - Submediterranean (MED-SUBMED), 77 taxa (26%); Central-European Mountainous (CEM) with 69 taxa (23%); Central-European (CE) with 34 taxa (11%); and Pontic (PONT) with six taxa (2%). Within SEM and CEM groups, the most abundant were Dinaric and Dinaric-Balkan elements, in the MED-SUBMED group it was Adriatic Submediterranean, while in the CE group there were Illyrian and Illyrian-Balkan floristic elements. The distribution of each taxon in B&H was mapped in the network of MGRS squares, with a precision level of 10 km. The richness of Balkan endemic flora in B&H was presented as the number of taxa, at the species and subspecies ranks in each MGRS square 10 x10 km. In the same way, the distribution of endemic taxa of each basic chorological groups was represented. It has been confirmed that high mountains of northern Herzegovina (Prenj, Cvrsnica, ...
