Status of Coral Reefs of the World: 2002 Nauru There is a narrow fringe of coral reefs around this island country. There has been limited research and no monitoring on these reefs during 2000-2002 due to a lack of capacity. Reefs on the west and to a large extent, the north and south sides of the island are in good health and show little sign of stress or destruction. However, reefs on the windward east side and in Anibare Bay have been disturbed by pounding waves from the east and construction of the Anibare Bay community harbour. The blasting destroyed many reefs within a 100m radius and the area is littered with debris and silt. Some damage occurred while installing an inlet pipe for the desalination plant at Meneng Hotel. Higher rainfall in early 2002 lowered salinity and caused coral bleaching on shallow reef areas. New Caledonia The most advanced coral reef monitoring among the Southwest Pacific countries occurs in New Caledonia. The ‘Coral Reef Observatory’ (ORC) was established in 1997 and surveyed 8 reef sites in 1997 and 1998. Funding ceased until 2001 when an NGO took over the monitoring. The crews of the Southern Province patrol boats were trained and now survey two sites – North Noumea (Nouville, Signal and Mbéré) and South Noumea GREENFORCE – STUDIES ON FIJI CORAL REEFS Greenforce, a non-profit UK organisation, provides host country institutions with biodiversity monitoring in areas with important natural resources. In 1998, the National Trust of Fiji asked Greenforce to collect baseline data and monitor the coral reefs around Yadua island and Yaduataba, and provide coastal management reports as a precursor to the establishment of a marine reserve and an application to UNESCO for World Heritage listing. Yaduataba is the home of the rare and endemic crested iguana. Greenforce has contributed monitoring data for 20 permanent sites, including pre- and post - 2000 bleaching reports, to the SW Pacific Node database. Before the 2000 bleaching event, hard coral cover was 30% at 5m and 10m, but afterwards it dropped to 14% at 5m and 12% at 10m. Recovery has been very slow at 5m, with only a 3% increase in coral cover, but at 10m, coral cover doubled to 24%. The proportion of stressed corals decreased at all depths from May to December 2000, but they now appear to be stressed again, although the massive and encrusting corals show less stress. The bleaching in 2000 had little impact on fish communities in Yadua, although an increase in the abundance of herbivorous fish was observed e.g. surgeonfish increased significantly from 18.4 (per 1000m 2 area) at 5m in 1999 to 30.7 in 2000 and 15.5 to 20.7 at 10m. Parrotfish increased from 21.7 to 39.1 at 5m and 26.2 to 38.09 at 10m. These increases may be due to increases in algal cover. Humphead wrasse and bumphead parrotfishes (major target species) are commonly sighted in Yadua. The most common length of the wrasse being 80cm (39 observations), with few over 120cm or under 30cm. The bumphead parrotfish occur in schools of up to 20 in some parts of the Island. Manta rays are also common with at least 9 individuals being regular visitors, and white tip reef sharks are seen in abundance on almost every dive. These trends may indicate that the management appears to be helping the fish populations recover. From: Andrew Finlay finlayrao@yahoo.co.uk and Oliver Taylor taylor_ojs@yahoo.com 186
Status of Coral Reefs in the Southwest Pacific Changes in coral cover over four years in North Noumea. Changes in coral cover over four years in South Noumea with an unknown impact causing losses after 1998. (Ricaudy, Maitre and Ever Prosperity), all in MPAs. In South Noumea, coral cover varied between 4% and 35% with evidence of considerable losses in 1998 and 2001, due to large numbers of crown-of-thorns starfish, coral bleaching, or coral disease. Unfortunately no monitoring was done in 1999 to confirm the cause of these declines. In North Noumea, coral cover ranged from 41% to 56% in late 2001, all being greater than the last observation in 1998, indicating a healthy recovery. Fish densities in these MPAs were reasonably healthy and included populations of major target species, such as coral trout or grouper (Plectropoma leopardus), Humpback grouper (Cromileptes altivelis) and Napoleon Wrasse (Chelinus undulates). There were also many butterflyfish, parrotfish and rabbitfishes at all sites. Surveys in December 2001 (southern summer) showed large populations of grouper and rabbitfishes, which were 187
