3. Coral composition, abundance and density Coral community structure was determined from 3121 corals, 4 cm in diameter or larger, that occurred within 72 transects on the 19 reefs. The density of corals within transects varied between sites from <1 coral/ m2 to a maximum of 8, with the highest densities recorded at sites PB-02,03,06, 07, 08, 09, 11 and 20 and the lowest at PB-15 (Fig. 12). Part of this difference could be attributed to the habitat/depth and also the abundance of each taxon (Fig. 13), which varied considerably among sites (Fig. 14). Number of corals/meter2

Fig. 12. Density of scleractinian corals (4 cm or larger in diameter) observed within belt transects (10 m X 1 m) on 19 reefs.

A total of 33 species were identified within these transects, with 13 occurring on more than 80% of the reefs surveyed and two species each occurring on a single reef. Nine species made up 94% of all corals assessed on the 19 reefs (Fig. 13). SINT CNAT Other MANN 7% MFAV 4% 1% 3% 8% DSTR 13%
