Current Population Sizes, Distribution Areas and Re-Evaluated IUCN Categories of Rare and Endemic Species from Central Anatolia, Turkey: Salsola grandis, Scutellaria yildirimlii and Sideritis gulendamii

Abstract

Salsola grandis, Scutellaria yildirimlii and Sideritis gulendamii are rare and edaphic endemic species, which grow on marly-gypseous soils. The reason that there exists discontinuous distribution for these species is because they need special habitat type. In this study, it is aimed to determine the current population size, distribution area and threat factors for these endemic species. It is also aimed to re-evaluate the IUCN threat category according to 2012 IUCN Red List Category and Criteria because an increase in the population size and the distribution areas were determined by the discovery of the new localities. For small populations, the population size was assessed by counting mature individuals one by one. For relatively larger populations, the number of mature individuals were estimated via randomly chosen sampling areas with the size of 25 m2. Including the new localities, 4 localities of Sa. grandis have the occupancy area of 16 km2 and the extent of occurrence area of 3529 km2. The estimated value of total number of mature individuals is 6067. Although the re-evaluation of collected data suggests that this species belongs to EN category, it is considered that CR category is the most suitable category for Sa. grandis regarding the risk of extinction in the near future. Sc. yildirimilii is distributed through 6 localities with the area of occupancy of 24 km2 and the extent of occurrence of 1305 km2. The estimated value of total number of individuals is 92934. Obtained results suggests that Sc. yildirimlii belongs to the category EN in terms of the extent of occurrence and the area of occupancy whereas it is categorized under VU in terms of number of locations according to 2012 IUCN criteria. However, it is believed that EN category is much more suitable for this species. Si. gulendamii, whose area of occupancy and extent of occurrence are 28 km2 and 5997 km2, respectively, has 7 localities. The estimated value of total number of mature individuals is 20563. Therefore, Si. gulendamii is re-evaluated in EN category according to 2012 IUCN Red List Categories and Criteria taking into account the extent of occurrence, number of locations and threat factors.
