The district of Akçakoca (Düzce) is located into the Western Black Sea Region and Euro-SiberianPhytogeographical Region in Turkey. In Akçakoca, there are 657 plant taxa. In this research, the generalvegetation of Akçakoca is recorded during the field trips between 2001 and 2003. The most of the area iscovered with broad leaves forest included Fagus orientalis, Carpinus betulus, Castanea sativa. Rhododendronponticum, Vaccinium arctostaphylos, Ilex colchica, Ruscus aculeatus and many Rubus sp. are recorded at theshrubs level. In the vegetation of sandy dune, Cakile maritima is widespread at the early spring and thenOtanthus maritima, Eryngium maritimum, Polygonum mesembricum, Polygonum maritimum, Salvia annua aredetermined. In addition that Myrtus communis, Laurus nobilis, Erica arborea, Arbutus unedo, Arbutusandrachne which are Mediterranean elements are grow up near the coastal area as a pseudomaquis.

Batı Karadeniz bölgesinin deniz kıyısında yer alan ve bitki coğrafyası bakımından Avrupa-Sibirya bölgesinegiren Akçakoca (Düzce) ilçesinde 657 bitki taksonu yetişmektedir. Bu araştırmada, 2001-2003 yılları arasındayapılan arazi gezilerinde ilçenin genel vejetasyonu tespit edilmiştir. Alanın büyük bir kısmı, baskın olarak Fagusorientalis (kayın), Carpinus betulus (gürgen), Castanea sativa (kestane)’ dan oluşan geniş yapraklı ormanlarlakaplıdır. Çalı katında Rhododendron ponticum (ormangülü), Vaccinium arctostaphylos (ayı fındığı), Ilexcolchica (ışılgan), Ruscus aculeatus (tavşan memesi) ve bir çok Rubus türleri göze çarpar. Kıyı kumulvejetasyonunda 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 yerlerdegörülerek yalancı makiyi oluştururlar.
