A new distribution area of endemic kasnak oak (Quercus vulcanica [Boiss. et Heldr. ex] Kotschy)

Abstract

Within the scope of this study, current distribution areas and habitat preferences of Kasnak oak (Quercus vulcanica [Boiss. et Heldr. ex] Kotschy) species, which is known as one of the most rarest oak species in the world, have been revealed and a new distribution area has been determined around Ankara-Nallıhan-Sarıcali Mountain for the distribution map. Within the new distributon area, extent of occurrence calculated to be 166.597.545 km2, an area of occupancy calculated to be 68.000 km2 so, the threat category was updated as Least Concern (LC) in this study. Latitude, longitude, altitude (m), geographic location, geographical exposure, slope (%), parent material type, vegetation type, vegetation height (m) and the data related to vegetation cover (%) and climate data were recorded and evaluated during 2018 and 2019 field work. In addition, 112 species and 11 endemic were identified in the same habitat of the Kasnak oak. Consequently, in order to protect the genetic resources of the Kasnak oak species which is endemic to the country, it is very important to update the current distribution areas of the species and to preserve the biological diversity of the country.
