    HORIZONTAL AND VERTICAL SPATIAL DISTRIBUTION AND LOSS OF GRASSLAND IN BOSNIA AND HERZEGOVINA
    (Geographical Institute "Jovan Cvijić" of the Serbian Academy of Sciences and Arts (SASA), 2022) Drašković, Branislav; Petronić, Slađana; Gutalj, Marko; Marić, Nataša
    Two databases related to grassland in Bosnia and Herzegovina (B&H) have been used in this research—the Copernicus Grassland (GRA) and CORINE Land Cover (CLC). The data have been processed by using GIS tools, and the spatial distribution of grass vegetation in relation to three biogeographical and four elevation zones has been determined. By using the Copernicus Water and Wetness (WaW) database, an insight into the coverage of grass vegetation in wetlands has been obtained. In addition, the analysis of changes in databases determined the total amount and location of the largest grassland losses. Based on GRA database, B&H is one of the richest countries, with 22.4% of its territory covered by grassland. According to the CLC database, pastures occupy 6.3% and natural grasslands 5.6% of the territory of B&H. However, grassland is exposed to various anthropogenic and natural processes that affect its distribution, quality, functions, etc. The CLC database has been processed by extracting the grasslands (pastures and natural grasslands) and calculating their spatial coverage and changes which happened during the three six-year periods from 2000 to 2018. The trend of decreasing pasture areas and increasing natural grasslands has been noticed. The pastures are most endangered by the processes of conversion to other types of agricultural land, while natural grassland increased spatial coverage during the period 2012–2018 mostly due to the revitalization and grazing of burned areas in the region of Herzegovina. Grasslands have been particularly targeted for afforestation and cropland conversion at present

    Urban Floristic Diversity in Bosnia and Herzegovina – the Reflection of Nature
    (Kluwer Academic Publishers, 2024) Lubarda, Biljana; Rat, Milica; Petronić, Sladjana; Sarajlić, Nermina; Marić, Nataša; Maksimović, Tanja; Anačkov, Goran
    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.
