Zooxanthellate scleractinian corals of the Calamianes Islands, Palawan Province, Philippines (Marine RAP Survey)

Zooxanthellate scleractinian corals were identified at 38 sites in the Calamianes Islands, Palawan Province, Philippines in 1998, using rapid assessment methods. Sites surveyed covered a diverse range of habitats including sandy areas, walls, overhangs, slopes and shallow reef areas. Areas where few or no corals were expected to be found, such as sea grass beds and mangroves were not surveyed. Surveys were conducted using SCUBA to a maximum depth of 40m. The survey method consisted of direct underwater observation of corals, usually during a single 60-90 minute dive at each site. Corals were recorded on a slow ascent from the base of the reef, along a zigzag path to the shallowest part of the reef. New, rare or unusual species were photographed and collected for further study. The aims of this survey were:1. to compile an inventory of corals on the reefs of the Calamianes Islands, Palawan Province, Philippines2. to use this information to compare the faunal richness of these islands with other parts of Southeast Asia and adjoining regions.
