Abstract

In this study, threat category of local endemic plant species Campanula damboldtiana was reassessed according to IUCN Red List Categories and Criteria. C. damboldtiana prefers special habitat type with marly-gypsaceous soils. The assessment based on new field data such as current population size, distribution areas and the main threats to this taxon. Field studies were carried out during the vegetation periods between 2017 and 2018. In addition to those parameters, soil samples were taken from each location and physical and chemical analyses were performed including pH, EC, gypsum, texture, CaCO3 parameters. Also, bioclimatic interpretations were made with the climatic data of the locations. With a recently discovered population, C. damboldtiana has three populations known from Ankara. The estimated total number of mature individuals was 8982. The area of occupancy and the extent of occurrence were calculated as 16 km2 and 16 km2, respectively. Considering our findings of C. damboldtiana, the IUCN threat category was reassessed as Critically Endangered (CR) as indicated in Red Data Book of Turkish Plants.
