Abstract

Posidonia oceanica (L.) Delile, an endemic species that plays a significant role in the ecosystem from the Strait of Gibraltar to the Sea of Marmara, is under the influence of the Anthropocene. The conservation of the species, which is one of the invaluable resources of the Mediterranean Sea, is essential to protect its unique ecological system. Nonetheless, the detection of the locations where the species exists is a prerequisite for its protection and the preservation of the associated habitat. Hence, the current investigation depicts the extent of P. oceanica coverage in Paşalimanı Island and the Narlı area of the Kapıdağ Peninsula located in the Sea of Marmara, which is the northern limit of the distribution of this species. The results obtained supported the determination of the area of P. oceanica in the Narlı region as 4.676 ha, and also the updating of this area to 21.861 ha for Paşalimanı Island, thus improving the existing information on their habitats.
