Twenty-seven years after a major Acanthaster planci outbreak on Rota, Saipan and Tinian, coral ocer has increased and reef community structure has changed. Many of the reefs are now dominated by species of the family poritidae, particularly; porites rus and p. cf. lutea. Acantheaster planci and culcita novaeguineae remain present in low densities on most of the reefs surveyed and continue to keep the populations of Acropordae and pocilloporidae low. The mean planula settlement rate observed was lower than that observed at other coral reefs in the Pacific, e.g., Fiji, the Great Barrier Reef and Guam. Juvenile coral recruits were dominated by species of the family poritadae while planulae recruitment was dominated by recruits from the family pocilloporidae (80%). In contrast to other reef systems in the Pacific, where acroporids dominate summer recruits, only 8 % of the recruits were acroporans.....
