Marine algal community of Gyonggiman islets on the West Sea of korea was investigated at the eleven islets during August 1993 and February 1994. A total of 82 marine algal species (9 green, 16 brown, and 55 red algae) was identified in these islets, including two sea grasses. Laminaria japonica plants, usually growing in the east and the south coast, were observed to occur in the lower tidal in Yonpyongdo. Deokjeokdo, Jawoldo and Poongdo showed a very similar floral characteristics in August. Corallina pilulifera, Sargassum thunbergii, Grateloupia filicina, and Gelidium divaricatum in the midtidal, were main species producing the highest standing crops in each islet. The algal standing crops was high with 52.9 g/m super(2) in August in Goolupdo and 51.9 g/m super(2) in February in Daeyonpyongdo. The algal community of Gyonggiman islets was characterized by Gloiopeltis furcarta - Gelidium divaricatum - Ulva pertusa or Grateloupia filicina - Gloiopeltis furcata - Enteromorpha spp. in the intertidal zone.
Key words: dominant species, marine algae, standing crops, vertical distribution
