Abstract

This research was performed in one of the important bird areas in Lake Van Basin, at Dönemeç
(Engil) Delta, (Van - Turkey) from April 2011 to April 2012. A total of, 91 species and 1 subspecies belongs
to 34 families were determined. Out of total, 34.7% (n:32) species were residents, 53.2% (n:49) were summer
visitors, 4.43% (n:4) winter visitors, 6.52% (n:6) non - breeding transit migrants and 1.08% (n:1) random species.
According to International Union for Conservation of Nature (IUCN) criterias, it was observed that one species was
endangered (EN), one species was near threatened (NT), one species was vulnerable (VU) and 89 species were least
concern (LC). The distribution of the species population in the area at six different habitats has been identifed and
habitats of the endangered species, in particular, have been highlighted by creating GIS-based distribution maps.

Dönemeç (Engil) Deltası’nın Mevsimsel Ornitolojik Potansiyelinin Belirlenmesi ve Coğraf Bilgi Sistemleri (CBS) Kullanılarak Sayısal Haritaların Oluşturulması

Abstract

Bu araştırma Van Gölü Havzası’ndaki önemli kuş alanlarından biri olan Dönemeç (Engil) Deltası’nda
gerçekleştirildi. Nisan 2011 ve Nisan 2012 tarihlerini kapsayan bir yıllık arazi çalışmaları sonucunda 34 familyaya
ait 91 tür ve 1 alttür tespit edildi. Bu türlerin 34.7% (32) Yerli, 53.2% (49) Göçmen, 4.34% (4) Kış ziyaretçisi, 6.52%
(6) Transit Göçer, 1.08% (1) Rastlantısal tür olduğu belirlendi. Alandaki türler Uluslararası IUCN kriterlerine göre
değerlendirildiğinde; 1 türün EN (Endangered), 1 türün VU (Vulnerable-Hassas), 1 türün NT (Near Threatened) ve
89 türün LC (Least Concern) statüsünde olduğu belirlendi. Alandaki türlerin, altı farklı habitatta populasyon dağılımı
belirlenmiş, özellikle nesli tehlike altındaki türlerin yaşam alanları GIS tabanlı dağılım haritaları oluşturularak öne
çıkarılmıştır
