Rediscovery and Neotypification of Festuca decolorata (Poaceae), an Endemic Species from Mount Uludağ (Türkiye) with Amended Species Description and Notes on Ecology, Distribution and Conservation

Jelena ErdalGencer Yaprakİbrahim Kaan ÖzgencilMusa Doğan

Festuca decolorata Markgr.-Dann. is a rare, endemic species from Mount Uludağ in Bursa province, Türkiye. It was described in 1981 based on a single scant herbarium sheet. No other specimen has been recorded ever since, and the species remained known only from the holotype. While conducting the revision of the genus Festuca in Türkiye, we learned that the type specimen itself was no longer present in the collection where it was deposited. During our field surveys in Mount Uludağ, we discovered a small population of F. decolorata for the first time after the type gathering in 1968. Considering that there is no other existing original material on which the name was based, we assigned a neotype for the species. In addition, we performed a detailed examination of the new material and provided an amended taxonomic description and additional data about anatomy, micromorphology, phenology and ecology. We also estimated the species’ potential distribution area using soil wetness, soil type, and forest cover as environmental predictors, and we used the resulting distributional data to assess the Red List status of the species. We found that the species is in grave danger of extinction with a maximum distribution area of only 6.15 km2 and urgent conservation measures are needed to ensure its existence.

Uludağ’dan (Türkiye) Endemik Bir Tür Olan Festuca decolorata’nın (Poaceae) Yeniden Keşfi ve Neotipifikasyonu, Güncellenmiş Tür Tanımı ve Ekolojisi, Dağılımı ve Korunması Üzerine Notlar

Jelena ErdalGencer Yaprakİbrahim Kaan ÖzgencilMusa Doğan

Festuca decolorata Markgr.-Dann. Türkiye’nin Bursa ilinde bulunan Uludağ’a özgü nadir, endemik bir türdür. 1981’de tek bir yetersiz herbarium örneğine göre tanımlanmış olup ve günümüze kadar holotip kaydı dışında kayıt alınmamıştır. Festuca cinsinin Türkiye revizyonu yapılırken tip örneğin artık depolandığı koleksiyonda bulunmadığı öğrenilmiştir. Uludağ’da gerçekleştirilen arazi çalışmaları sırasında, 1968’deki kayıttan sonra ilk kez küçük bir F. decolorata popülasyonu tespit edilmiştir. Ayrıca, yeni materyallerin ayrıntılı incelemesi yapılmış ve düzeltilmiş bir taksonomik tanım hazırlanarak türün anatomisi, mikromorfolojisi, fenolojisi ve ekolojisi hakkında ek veriler sunulmuştur. Çevresel belirleyiciler olan toprak nemi, toprak türü ve orman örtüsü kullanılarak türün potansiyel dağılım alanı tahmin edilip ve elde edilen dağılım verileri, türün Kırmızı Liste durumunu değerlendirmek için kullanılmıştır. Maksimum dağılım alanı sadece 6.15 km2 olan türün ciddi bir yok olma tehlikesiyle karşı karşıya olduğu ve korunması için acil önlemlere ihtiyaç duyulduğu tespit edilmiştir.
