Benthic community structure was studied by sample quadrates on transects at depths of 5 to 10 m in four sites, including Wanlitong, Leidashih, Siangjiao Bay, and Longkun, in coral reefs of southern Taiwan from 2003 to 2005. Totally 154 species in 45 genera of hard coral and 45 species in 10 genera of soft coral, representing 67% of known coral species were recorded. Covers of benthic organisms and hard coral growth forms were similar among years, but were significantly different among sites. Mean cover of all corals was high in Siangjiao Bay (56.88%) and Leidashih (65.69%), but hard coral (65.43%) was dominanted in Siangjiao Bay while soft coral (39.00%) was dominanted in Leidashih. Mean cover of all coral and benthic algae was similar in Wanlitong and Longkun. For hard coral growth forms, massive and encrusting corals were dominanted in three of four sites. This may be resulted from the strong wave. Cover of bare substrate was high (21.39%) in Longkun which was the most exposed to wind and wave stress. Foliaceous coral was abundant with the dominated species, Montipora aequituberculata (20.59%) in Siangjiao Bay which was a more protected site. However, foliaceous coral was more susceptibe to typhoon. Coral diversity was higher in Leidashih. This was related to both hard and soft corals were common and no dominant species. Comparing to previous studies, the long term change of coral abundance shows stable and/or increasing trends. It may be related to the dominance of massive and encrusting coral communities in southern Taiwan.
