Özet:

 The Macedonian oak Quercus trojana Webb is a mostly small- to medium-sized broad-crested deciduous tree that shows an interrupted distribution starting from Southern Italy in the far west and spreading eastward, covering the Balkans as well as western and southern Türkiye. Macedonian oaks do not form pure stands. They mix with other oak taxa in broad-leaf forests and with shrubs and small trees in sclerophyllous habitats and can also be found in black pine Pinus nigra J. F. Arnold, Turkish pine P. brutia Ten., Taurus cedar Cedrus libani G. Olivier, and Taurus fir Abies cilicica Antoine  Kotschy Carrière forests. According to the records and distribution areas published by different researchers, although no record exists for Macedonian oaks in the northern area of Central Anatolia or in Ankara, this study has determined the species to be distributed in the area northwest of Ankara. The article aims to examine the distribution areas of Macedonian oak in Türkiye and to present a new distribution area and the botanical characteristics of the specimens within this distribution area. The study has identified an assemblage of Macedonian oak between 900-1100 m above sea level around the village of Çakıloba in Ankaras Beypazarı district. A detailed comparison of the herbarium specimens collected from the area was made with Macedonian and Lebanese oaks, and all the measured parameters were found to be compatible with Q. trojana while differing from Q. libani, especially with respect to the length of the petiole and short sharp-edged teeth along the leaf margins. In terms of habitat, while the Macedonian oak trees are the dominant species in some locations, they are also found in mixed forests of downy oak Q. pubescens and black pine. In the studied area, two monumental Macedonian oak trees between 75-85 cm in diameter and between 150-200 years old were also found. The closest Macedonian oaks to this newly discovered community around Ankara are located further west in the provinces of Bilecik, Kütahya, and Eskişehir at a bird-flight distance of 150 km.

 Çoğunlukla küçük-orta boylu, geniş tepeli, yaprağını döken bir ağaç olan Makedonya meşesi Quercus trojana Webb, en batıda Güney İtalyadan başlayarak doğuya doğru Balkanlar ve Türkiyenin batısı ile güneyini kapsayan kesintili bir yayılış gösterir. Makedonya meşesi saf ormanlar oluşturmamaktadır. Yapraklı ormanlarda diğer meşe taksonlarıyla, maki elemanı çalı ve ağaççıklarla karışıma girmekte, ayrıca karaçam, kızılçam, sedir ve Toros göknarı ormanlarında da bulunabilmektedir. Farklı araştırmacılar tarafından günümüze kadar yayınlanan kayıt ve yayılış alanlarına göre, Makedonya meşesinin İç Anadolunun kuzeyinde ve Ankarada kaydı bulunmamakla birlikte bu çalışma ile birlikte türün Ankaranın kuzeybatısında yayılış gösterdiği tespit edilmiştir. Makalenin amacı, Makedonya meşesinin ülkemizdeki yayılış alanlarını irdeleyerek yeni bir yayılış alanını ve bu yayılış alanındaki bireylerin botanik özelliklerini tanımlamaktır. Çalışma ile Ankaranın Beypazarı ilçesi, Çakıloba mahallesi civarında 900-1100 m yükseltiler arasında Makedonya meşesi topluluğu tespit edilmiştir. Alandan toplanan herbaryum örnekleri, morfolojik özellikleri en yakın olan Makedonya ve Lübnan meşesi ile detaylı olarak karşılaştırılmış olup ölçülen tüm parametreler Q. trojana türü ile uyumlu bulunurken özellikle yaprak sapı boyu ve yaprak kenarı dişlerinin kısa olmasıyla Q. libani türünden ayrılmaktadır. Beypazarı Çakılobanın güneyinde yaklaşık 4 km civarı bir hat boyunca Makedonya meşesi yer yer hâkim tür olmak üzere, tüylü meşe ve karaçam ile birlikte karışık ormanlar oluşturmaktadır. Ayrıca, alanda iki farklı mevkide 75-85 cm çaplı ve 150- 200 civarı yaşlı anıtsal Makedonya meşesi örneklerine de rastlanmıştır. Ankaradan Makedonya meşesinin ilk kaydı niteliğindeki bu topluluğa en yakın Makedonya meşeleri daha batıda Bilecik, Kütahya ve Eskişehir illerinde, kuş uçuşu 150 km civarı mesafededir.
