Studies have been made of the recolonization of marine benthic algae on cleared natural surfaces over a 21-mo period (July 1986 to April 1988) at interidal zones of Muchangpo and Maryangri, western coast of Korea. Surfaces were sterilized by burning after clearing. In general, the successive stages found in the permanent quadrats were blue-greens or filamentous algae-membranous algae-perennial algae. However, the nature and position of the surfaces and length of time of exposure have been shown to influence the population which develops. It was concluded that a community can be attained after 18 months since the substrata were cleared.
