In order to manage and conserve coral reefs it is essential to understand the factors that structure reef communities. In Indonesia’s Jakarta Bay – Pulau Seribu reef complex, pronounced on-to-offshore variation in a number of variables was observed. Live coral cover, and echinoderm and fish species richness were higher in midshore sites than either in- or offshore sites. Variation in habitat structure, the abiotic environment, distance between sample sites and covariation of these factors separately explained 9.6 to 15.1%of the spatial variation in the composition of corals, echinoderms and fishes. Together, all three components explained > 50%of the variation in composition. This indicates that spatial and environmental factors influence the distribution of species across the study area and have important implications for the large-scale management of this reef ecosystem. Large scale management and protection of these reefs will probably be important because the majority or reefs were in poor to very poor condition as exemplified by low (
