Standard Classification of Intertidal Habitats in North Qeshm Island (Persian Gulf)

Abstract

As a new approach to ecological classification, the “Coastal and Marine Ecological Classification Standard (CMECS)” was applied to 141 km of the northern intertidal stretch of Qeshm Island during 2010. Biotic Cover and Surface Geology as the two components of the classification were used. Considering the extent and geomorphology of the area, 9 sites were designated using GPS. Density and distribution of biotic community were determined using 0.5×0.5 m quadrate and sediment was sampled up to 15 cm below the surface. Totally 32 codes were determined for 40 habitats (biotopes), and their positions were displayed on map by GIS. <i>Acar</i> spp., <i>Barbatia</i> sp. (molluscs), and <i>Zoanthus</i> sp. (cnidarian) can be regarded as the rocky substrates’ specific biotopes, while <i>Stichodactyla</i> sp. (cnidarian) and <i>Halophia</i> sp. (seagrass) can be regarded as the sandy substrates’ specific biotopes.
