Flora and community structure of benthic marine algae in Dangjin Province, western coast of Korea

A intertidal marine benthic algal vegetation at Dangjin, the western coast of Korea was investigated to clarify the community structure and the pattern of geographical distribution along a coast line between November 2002 and October 2003. Total 60 species including 10 of green algae, 15 of brown algae, 35 of red algae were collected and identified. Among these species, 6 species were found throughout the survey period by Ulva pertusa, Laminaria sp., Corallina pilulifera, Prionitis cornea, Gracilaria verrucosa, Chondrus ocellatus. Marine algal species of total vegetation at study sites, maximum algal species was recorded in autumn and winter seasons, and decreased in spring and summer seasons. The (R+C)/P value reflection flora characteristic was 3.0 and composition of seaweed flora was changed to the temperate flora. In conclusion, the number of marine algal species and diversity in this area were remarkably reduced comparing with the previous studies in western coast of Korea.
