Abstract:

 The kasnak oak Quercus vulcanica Boiss. and Heldr. ex Kotschy is an endemic oak species in Türkiye whose largest distribution area is in the western part of the Turkish Lake District. The literature on current plant studies has emphasized some of the natural distribution areas of the kasnak oak in Türkiye to be found in the Murat, Türkmen, and Şaphane mountains in Kütahya province. The kasnak oaks distribution is unknown regarding Budağan Mountain İnyanı Peak 1612 m which lies between Tavşanlı and Emet districts in western Kütahya. The field studies carried out in July 2022 on Budağan Mountain were the first to identify the presence of the kasnak oak there. Kasnak oaks are located in the dry forest area formed of junipers on land made of limestone at an altitude range of 1430-1600 m on Budağan Mountain, with dolines offering a more favorable environment in terms of humidity, especially on the northern side of the mountain. Young kasnak oak groups develop at the base of the dolines and have a height of 3-4 m Individual oaks can reach 80 cm in diameter and 12 m in length. This study involves the natural distribution of the kasnak oak, an endangered NT group according to the risk categories of the International Union for Conservation of Nature IUCN, on Budağan Mountain, an area that has not been previously studied in detail. In addition, the study aims to contribute to the information about the natural distribution of this endemic species and to reveal the areas ecological characteristics.

 Türkiyedeki endemik meşe türlerinden biri olan kasnak meşesi Quercus vulcanica Boiss. and Heldr. ex Kotschynin Anadoluda en geniş yayılış alanı Göller Yöresinin batı kesimidir. Mevcut literatürde, Türkiyedeki doğal yayılış alanları içerisinde kasnak meşesinin Kütahya ilinde Murat Dağı, Türkmen Dağı ve Şaphane Dağında olduğu vurgulanmaktadır. İlin batısında, Tavşanlı ile Emet ilçeleri arasında yükselen Budağan Dağı İnyanı Tepe 1612 m üzerindeki yayılışı bilinmemektedir. Budağan Dağında Temmuz 2022 yılında yapılan arazi çalışmaları esnasında kasnak meşesinin varlığı ilk defa tarafımızca tespit edilmiştir. Kasnak meşesi Quercus vulcanica Budağan Dağının 1430-1600 m yükseltileri arasında kalker yapılı arazide, ardıçların oluşturduğu kuru orman sahasında, nem bakımından daha elverişli bir ortam sunan dolinlerin içerisinde özellikle kuzeye bakan yamaçlarında bireyler halinde yer almaktadır. Dolinlerin tabanlarında ise 3-4 metre boya sahip gençlik halinde kasnak meşesi toplulukları gelişme imkânı bulmuştur. Meşe bireylerinin çapı 80 cm yi, boyu ise 12 metreye kadar çıkmaktadır. Bu çalışma, Dünya Doğayı Koruma Birliği IUCN nin risk kategorilerine göre Tehdit Altında NT grubunda yer alan daha önce hakkında detaylı araştırma yapılmamış kasnak meşesinin Budağan Dağındaki doğal yayılışını konu almaktadır. Ayrıca, bu endemik türün doğal yayılışı ile ilgili bilgilere katkı sağlamayı ve sahanın ekolojik özelliklerini ortaya koymayı da amaçlamaktadır.
