Abstract
The determination of the flora and fauna structure of university campus areas, which can be evaluated within
the scope of urban ecosystem with high human population and large living areas, is important in terms of determining the
biological diversity of the related areas. Furthermore, the identification of the relevant species provides a resource for the
assessment of environmental and socioeconomic impacts. This study was carried out between 2018-2019 on the
determination of herbaceous plant species and their definition of impacts in Düzce University Konuralp Central campus,
located in Düzce Province, Turkey. The main purpose of the study is to create a resource for the establishment of necessary
measures and control programs against herbaceous plant species in the campus area and for the protection of the
biological diversity and strategies of the relevant area. Based on the results, 65 taxa from 27 families were determined. The
families with the most taxa were Asteraceae, Poaceae, Fabaceae and Cruciferae. When the lifetime of taxa is examined, 33
taxa have annual, one taxon has biennial, 22 taxa have perennial and nine taxa have common lifetime. According to the
frequency of occurrence; Lamium purpureum and Veronica persica were the most common species with 84.4%. The
species following were Anagallis monelli (81.2%), Medicago arabica (72%), Poa bulbosa (72%), Ranunculus repens
(69%), Plantago lanceolata (69%), Conyza canadensis (66%) and Lolium perenne (66%), respectively. As a result of the 65
taxa identified in the campus area having different impact patterns, 108 impacts were evaluated in terms of environmental
(68) and socioeconomic (40) aspects. While the most impact types were determined in the impact of strong reproduction
and spreading with 34 taxa, this was followed by the impact on landscape texture with 26 taxa. When the impact statuses
were examined, 65 negative and 43 positive impacts were detected. The results may provide resources for the
establishment of necessary measures and control programs to reduce the negative effects of herbaceous plant taxa in campus
areas. In addition, it can help develop strategies to preserve positive effects and biodiversity. Lastly, these data may be used
to monitor herbaceous plant taxa changes in the campus area of Düzce University in the coming years.
