Investigation of floristic composition of Gaziantep and its neighboring villages in terms of hemeroby

In this study, the flora of Gaziantep province, which is one of the most important cities in Turkey with regard to population, was investigated in terms of hemeroby.Within the limits of the study, 215 sampling fields were determined in the city center and neighboring villages and their present floristic compositions were examined. The results revealed 87 families and 395 taxa belonging to 258 genera. Among these species, 18 of them were endemic while 119 of them were exotic and plantation. According to the IUCN threat categories; two of the endemic taxon belonged to CR categorization, four of them belonged to VU, and 12 of them belonged to LR categorization. Results of the analysis of floristic composition of sampling fields with TWINSPAN Multivariate statistical program, 7 different groups in terms of absence/presence were determined. In addition, 17 different biotopes were identified according to floristic content of the study area.The places of these species? floristic contents were specified in hemeroby scale. Soil samples were collected from the habitats of these plants, and chemical and physical analyses were performed on these samples. Multivariate Statistical analyses were also carried out on the ecological results obtained. Soil samples belonging to the plants mentioned were found to have been highly contaminated due to urban factors, and accordingly, the floristic composition and habitats structure of the region exhibited high synanthropic features.
