The urban flora of Imotski

Recently, the flora of the cities of many European countries has been explored to identify new plant species that have a positive or negative impact on the existing flora. In this paper, the urban flora of the town of Imotski was studied with the aim to provide a list of autochthonous and alohtonous plant species, taxonomic analysis of flora and habitat types. The urban flora of Imotski contains 321 plant species of vascular plants distributed on 9 anthropogenic ruderal habitats. The most dominant families in the investigated flora are Asteraceae (48.5%) and Poaceae (43.0%). The dominant life-form categories of flora in the area of Imotski are terophytes (37.5%). ). The analysis of floral elements shows that wide spread plants (26.6%), Mediterranean (23.0%), cultivated and adventive plants (22.4%) are most represented. Dominant plant species on ruderal habitats are Ailanthus altissima, Avocular polygonum, Cynodon dactylon, Portula oleracea, Setaria viridis, Chenopodium album and Conyza canadensis. According to the total number of species in flora, 11% of the species belongs to the alohton adventive plants (neophytes), which are constantly spreading into the composition of natural and anthropogenic habitats. Most of the neophytes originate from the American continent (22 plant species or 63.0%). One of the most invasive species in the flora of Imotski as well as in the flora of Croatia is Ailanthus altissima which spreads to almost all habitats of the urban flora of Imotski. In the investigated flora of Imotski, two endemic species belonging to the Illyrian Adriatic endemic plants and four endangered plant species were found. The influence of man and further urbanization decreases the natural habitats and increases the proportion of ruderal habitats in the flora of Imotski with alohton flora.
