A coastal area is a confluence of land and marine ecosystems and includes the independent biological, ecological, and geological area. Increasing pressure on these areas can decrease the quality of marine habitats, and can even lead to the loss of sensitive habitats. In this regard, a “biotope” has been suggested as the most informative operational unit for research and management. These biotopes, however, have been specified by the dominant species; they depend on the seabed, they are stable, and sometimes are used synonymously with the word ecology. Habitat classifications are, therefore, most accurate and ecologically relevant at the biotope level because of the direct relationship between the biota and their environment. The Coastal Marine Ecological Classification Standard (CMECS) was developed with the input of over 40 coastal and 20 marine habitat experts and presents a universally accepted standard classification for coastal and marine habitats. ... We classified the eastern coast of Mazandaran Province (Babolsar to Amirabad Port) and then encoded this zone based on the CMECS model
