The district of Akçakoca (Düzce) is located into the Western Black Sea Region and Euro-Siberian

Phytogeographical Region in Turkey. In Akçakoca, there are 657 plant taxa. In this research, the general

vegetation of Akçakoca is recorded during the field trips between 2001 and 2003. The most of the area is

covered with broad leaves forest included Fagus orientalis, Carpinus betulus, Castanea sativa. Rhododendron

ponticum, Vaccinium arctostaphylos, Ilex colchica, Ruscus aculeatus and many Rubus sp. are recorded at the

shrubs level. In the vegetation of sandy dune, Cakile maritima is widespread at the early spring and then

Otanthus maritima, Eryngium maritimum, Polygonum mesembricum, Polygonum maritimum, Salvia annua are

determined. In addition that Myrtus communis, Laurus nobilis, Erica arborea, Arbutus unedo, Arbutus

andrachne which are Mediterranean elements are grow up near the coastal area as a pseudomaquis.

Akçakoca (Düzce) İlçesinin Genel Vejetasyonu Üzerine Bir Araştırma

Öz

Batı Karadeniz bölgesinin deniz kıyısında yer alan ve bitki coğrafyası bakımından Avrupa-Sibirya bölgesine

giren Akçakoca (Düzce) ilçesinde 657 bitki taksonu yetişmektedir. Bu araştırmada, 2001-2003 yılları arasında

yapılan arazi gezilerinde ilçenin genel vejetasyonu tespit edilmiştir. Alanın büyük bir kısmı, baskın olarak Fagus

orientalis (kayın), Carpinus betulus (gürgen), Castanea sativa (kestane)’ dan oluşan geniş yapraklı ormanlarla

kaplıdır. Çalı katında Rhododendron ponticum (ormangülü), Vaccinium arctostaphylos (ayı fındığı), Ilex

colchica (ışılgan), Ruscus aculeatus (tavşan memesi) ve bir çok Rubus türleri göze çarpar. Kıyı kumul

vejetasyonunda ise erken ilkbaharda Cakile maritima çok yaygınken zaman geçtikçe Otanthus maritima,

Eryngium maritimum, Polygonum mesembricum, Polygonum maritimum, Salvia annua gibi bitkiler görülür.

Ayrıca, araştırma alanında aslında Akdeniz elementi olan Myrtus communis (mersin), Laurus nobilis (defne),

Erica arborea (funda), Arbutus unedo (koca yemiş), Arbutus andrachne gibi türler kıyıya yakın yerlerde

görülerek yalancı makiyi oluştururlar.
