Natural Colonisation of a Marina Seawall by Scleractinian Corals along Singapore's East Coast

— Highly modified habitats resulting from coastal development could facilitate the re-establishment of biological communities. At the Singapore Armed Forces Yacht Club in Changi, Singapore, the diversity and distribution of scleractinian corals were investigated using belt surveys at two different depths (1–3.5 m and 3.5–6 m) of a seawall. The 1,762 scleractinian colonies recorded are represented by 37 genera from 14 families. The dominant genera, in descending order, were Pectinia, Porites, Turbinaria, Goniastrea, and Leptastrea. Generic richness, abundance, and evenness were lower in the deeper belts. The majority of the colonies in the marina were juveniles smaller than 10 cm across, indicating that coral recruitment is an active, ongoing process, and that such environments, albeit highly modified, can function to support scleractinian diversity.
