Özet:

 This study aims to investigate the distribution of the Eurasian otter Lutra lutra, an important component of Türkiyes mammalian fauna, in the wetland ecosystems of Bilecik province, formed by the Sakarya River, and to identify the factors affecting biodiversity in the region. The Eurasian otter is classified as a species at risk by the IUCN and is listed as Near Threatened NT, facing various threats such as habitat loss and pollution. In this study, fieldwork was conducted in the wetland areas of Bilecik province, taking into account previously identified suitable habitats. Observations were carried out over four seasons, and indirect monitoring methods such as spraint and footprint tracks were used to detect the presence of the Eurasian otter. Additionally, technological tools such as drones and cameras were utilized during the research process. Information from local people, including fishermen, hunters, and farmers, was collected, and the study focused intensively on the specified regions. As a result of the fieldwork, four potential regions for otter habitation were identified, but detection was only made in two locations. The research findings will significantly contribute to the development of effective management strategies for the conservation of otter populations in the region.

 Bu çalışma, Türkiyenin memeli faunasının önemli bir bileşeni olan Avrasya su samurunun Lutra lutra, Sakarya Nehrinin oluşturduğu Bilecik ili sulak alan ekosistemlerindeki dağılımını araştırmayı ve bölgedeki biyolojik çeşitliliği etkileyen faktörleri belirlemeyi amaçlamaktadır. Avrasya su samuru, IUCN tarafından risk altındaki türler arasında sınıflandırılmakta ve Tehdide Yakın NT olarak listelenmekte olup, habitat kaybı ve kirlilik gibi çeşitli tehditlerle karşı karşıyadır. Bu çalışmada, Bilecik ili sulak alanlarında, daha önce belirlenmiş uygun habitatlar göz önünde bulundurularak arazi çalışmaları yürütülmüştür. Dört mevsim boyunca gözlemler yapılmış ve Avrasya su samurunun tespiti için kullanılan, dışkı ve izler gibi dolaylı izleme yöntemleri kullanılmıştır. Ayrıca, araştırma sürecinde drone ve kameralar gibi teknolojik araçlardan yararlanılmıştır. Balıkçılar, avcılar ve çiftçiler dahil olmak üzere yerel halkın bilgileri toplanarak çalışmalar belirtilen bölgelerde yoğunlaşmıştır. Arazi çalışmaları sonucunda, su samuru yaşamı için dört potansiyel bölge belirlenmiş, ancak yalnızca iki lokasyonda tespit yapılabilmiştir. Bu araştırma, bölgedeki biyolojik çeşitliliğin önemini vurgulamakta ve Avrasya su samuru türünün korunmasına yönelik stratejilerin geliştirilmesine katkıda bulunabilir niteliktedir.
