Özet

Coastal habitats are very fragile and specialized environments susceptible to human activities and therefore vegetation ecology studies are needed to predict responses to landscape monitoring. There is little information about plant species invading human-made habitats, and no study has been carried out in Turkey on plant species distributed on coastal revetments. Therefore, the present study aimed to present the findings of a survey of plant species in relation to habitat factors to coastal revetments in the city of Trabzon (northeastern Turkey) and to identify and suggest species for future landscaping and environmental remediation works. The fieldwork was undertaken within the boundaries of Trabzon province. Data were collected along three habitat types regarding coastal revetments obtaining a total of 1,277 taxa collected from 46 different revetment areas including 150 sample plots. So, 169 plant species were identified, three of which were the most frequent with high presence of Conyza canadensis L. (44.67 %), Clematis vitalba L. (24.67 %) and Daucus carota (22.67 %). Using descriptive statistics of different diversity indices for plant species present in the three revetment types, significant variations were found in Shannon's diversity index (H'), species richness index (R') and Pielou's evenness index (J'). The results of the regression analysis of relationships between habitat factors and diversity of species indicated that distance from the road and distance from the sea totally affected the diversity and distribution of the species on coastal revetments. Consequently, the ecological roles of the species on coastal revetments are discussed in the conservation and management context. Therefore, when selecting plants to be used in the landscaping of coastal areas and deciding where they should be planted, habitat factors should be considered to have a significant effect on the alpha diversity of plants that can be suggested.
