Status of Quercus vulcanica conservation in Europe
There are few genetic studies on kasnak oak. Studies that do exist suggest it has high levels of genetic variation and low genetic differentiation, like other oak species (Sarikaya et al., 2022).
The bibliographic review was conducted by James Chaplin of the EUFORGEN Secretariat in August 2024.
Kasnak oak is closely related to Hungarian oak (Quercus frainetto) with little genetic differentiation between the two species. However, the species differ morphologically and can be genetically differentiated (Yücedağ, Müller, and Gailing, 2021).
Kasnak oak had a wider distribution in Anatolia, especially in the north, prior to the Last Glacial Maximum (Sarikaya et al., 2022). After the last glacial maximum, the species spread from the north to the south of Türkiye (Sarikaya et al., 2022).
The bibliographic review was conducted by James Chaplin of the EUFORGEN Secretariat in August 2024.
Kasnak oak can grow only in some small, isolated locations scattered across Türkiye (Sarikaya et al., 2022). It currently grows on a total area of approximately 10 000 hectares. Its past distribution was much wider but declined because of destructive human activity including deforestation and agricultural expansion (Dutkuner and Genç, 2001). The species is now Near Threatened according to the International Union for Conservation of Nature risk categories and continues to be threatened by destructive human activities (Sarikaya et al., 2022). The genetic diversity of kasnak oak is at risk from genetic drift, inbreeding, and hybridization (Sarikaya et al., 2022). Future climate changes are also expected to reduce the species’ population size and distribution (Sarikaya et al., 2022).
New nature reserves for kasnak oak should be established in areas with climate that will remain suitable in the future, with the focus on the north-western Black Sea region of Türkiye, where the species is currently growing. More genetic studies are needed to provide a more complete understanding of both historical biogeography and intraspecific diversity of the species to help guide conservation actions (Sarikaya et al., 2022).
The bibliographic review was conducted by James Chaplin of the EUFORGEN Secretariat in August 2024.
