Coral reefs are one of the most threatened ecosystems in the world. Rivalling terrestrial rainforests in their biological diversity, and providing major economic benefits from fisheries and tourism, coral reefs ecosystems are of global concern. In addition, reefs provide many vital functions in developing countries, especially in Small Island Developing States. Until recently, stresses caused by human activities – such as land-based sources of pollution and destructive fishing practices – were considered to be the primary dangers to coral reefs. While these problems still persist, the last two decades have seen the emergence of yet another, potentially much greater threat. Coral reefs have been affected, with increasing incidence and severity, by coral... |

It is important to establish benchmark reef locations that are remote from centres of human activity and free from anthropogenic disturbances, against which human impacts elsewhere can be assessed and rates of recovery evaluated. Aldabra Atoll in the southern Seychelles, is free of anthropogenic disturbances and an ideal location in which to study reefs and adjacent ecosystems. It has further significance with it being in the middle of a region which has been classified as having a number of reefs at high risk (Bryant et al., 1998) and has been designated as a UNESCO World Heritage site. |

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... |

Assessing environmental impacts and monitoring ecosystem recovery requires an understanding of the underlying spatial and temporal changes that have occurred. There are three main questions to be answered with specific reference to the Indian Ocean and the current status and future of coral reef ecosystems: i) what are the effects of widespread coral mortality going to be in the Indian Ocean, ii) how long will it take for reef ecosystems to recover, and iii) will ‘recovered’ systems have the same structure and functional integrity? Research into these questions must bear in mind that most measurements to be made are points on a long-term trend. Although there may be another disturbance event similar to that of 1998, its occurrence (if it occurs) should not... |
