Bu çalışmada Samsun ilinde
kumul ekosistemlerde yayılış gösteren nadir türler araştırılmıştır. Araştırma
Samsun kıyısında Çobanyatağı (Terme), Sindel, Hürriyet ve Costal (Çarşamba),
Cernek, Sahilkent (Bafra) ve Doyran (Alaçam) lokalitelerinde yürütülmüştür. Kumul
komuniteleri Nisan 2010’dan Temmuz 2012’ye
kadar, en
küçük alanlar metodu kullanılarak 16 m² lik örnek
parseller şeklinde örneklenmiştir. Çobanyatağı, Sindel, Cernek,
Sahilkent ve Doyran lokalitelerinde üst kumsal (sürüklenme çizgisi), primer
kumul, esas kumul, geçiş kumulu ve stabil kumul zonlarından oluşurken, Costal
ve Hürriyet lokalitelerinde ise özellikle yerleşim alanlarının açılması
nedeniyle stabil kumul zonu tamamen yok olmuş, geçiş zonu da önemli derecede
kesintiye uğramıştır. Nadirlik indeks formülü ile her lokalitede bulunan
zonların nadir türleri belirlenmiştir. Sonuç olarak her bir lokalite bağımsız
olarak değerlendirilmiş ve nadirlik indeks formülüne göre 47 türün nadirlik
indeksinin düşük olduğu tespit edilmiştir.

Rare dune plant species in Samsun Province, Turkey

In the present study, the rare species of the city Samsun which
distributed in sand dune ecosystem were investigated. The study was carried out
in the localities Çobanyatağı (Terme), Sindel, Hürriyet and Costal (Çarşamba),
Cernek, Sahilkent (Bafra) and Doyran (Alaçam) of Samsun sand dune. Sand dune
communities were sampled from April 2010 to July 2012 by using minimal area
method in 16 m² plots. The coastal sand dunes of Çobanyatağı,
Sindel, Cernek, Sahilkent (Bafra) and Doyran (Alaçam) is consist of upper beach/driftline,
primary/embryonic, main, transitional and, fixed dune zones ) while the fixed
zone is totally disappeared and transitional zone is significantly interrupted
in the localities Costal and Hürriyet especially due to the building
settlement. Rare species on each coastal dune zones in all localities were
determined according to the rarity index formula. As a result, each locality was
assessed independently, and it is indicated that the rarity index of 47 species
is low.
