The development of a sessile marine community of 29 animal species on mild carbon steel panels and black perspex control panels submerged off the south coast of England was studied over a two year period. There was an overall negative effect of steel on community development. Settlement by fouling species generally occurred later on steel panels, and the percent cover achieved was usually less on steel than on perspex. Significantly reduced cover on steel was found in nine species. Species differed in their response to the two materials: some. e.g. barnacles, showed much reduced cover on steel. most showed a modest reduction, but a few. e.g. some hydroids, showed occasional positive responses to steel, possibly due to reduced competition for space on steel surfaces. Differences in community composition were greatest early on and decreased towards the end of the experiment. Corrosion of steel panels proceeded from a powdery stage, probably inimical to settlement, to a stage in which hard scales of rust developed. The rate of weight loss of steel panels through corrosion decreased during one experimental series, possibly due to shielding by the fouling community.
