Reef Systems of the Islands of the Southern Seychelles

Coral reefs
There are 74 coralline islands in the Southern Seychelles, from which representative reefs have been selected for this report, comprising an atoll (Alphonse), a raised platform island (St Pierre), a carbonate bank (Providence-Cerf) and a drowned atoll (Cöetivy) (Figure 1). Aldabra Atoll is treated in a separate section in this publication (see Teleki et al., this volume).
Qualitative observations of reef morphology, coral community composition and reef health in the southern Seychelles were made between March and May 1998 (Southern Seychelles Atoll Research Programme - SSARP), February and March 1999 (Thalassi/Shoals of Capricorn Expedition) and November 1999 (Aldabra Marine Programme – AMP). These observations were supplemented by quantitative descriptions of coral communities at 48 sites at four study locations. Twenty-five meter long transects were set out at water depths, where possible, of 5 m, 10 m, 15 m and 20 m. Transects were surveyed using both a line point intercept method and digital videographic imagery which was subsequently analysed using point sampling to generate estimates of benthic cover. Digital stills of individual coral species were obtained from each site for taxonomic inventory purposes.
