Introduction The Semporna district lies at the extreme southeast corner of the east Malaysian state of Sabah in the Sulawesi Sea. The district waters contain parts of the globally significant (for biodiversity) Semporna Priority Conservation Area (PCA) of the Sulu-Sulawesi Marine Ecoregion (SSME). This area lies well within the Coral Triangle and thus is within the richest areas in the world. Malaysia’s largest concentration of coral reefs is found here, along with large expanses of mangroves and seagrass beds. The area boasts a wide diversity of coral reef geomorphology, including a barrier reef formation, fringing reefs, patch reefs, a pre-atoll, and Sipadan Island, an oceanic seamount. There is one existing marine protected area in the district which covers 350 km2 out of the approximately 7680 km2 of Semporna PCA. The Tun Sakaran Marine Park contains 8 islands and is the first marine protected area in Malaysia to include local communities within its boundaries. Sipadan Island’s waters are proposed as a park and the intention to gazette was published in mid-2009. The status of the coral reefs in Semporna is largely unsurveyed and unreported to date, except for areas that have been surveyed by Sabah Parks, the University Malaysia Sabah, the Marine Conservation Society (UK), and WWF-Malaysia. These have been limited particularly to Sipadan Island and the Tun Sakaran Marine Park. Sipadan Island survey data in 1994 show that live hard coral cover at shallow reefs (5–10 m) was high in all areas (up to 95%). Whereas the mid-depth slope (10–25 m) with the best coral growth cover was estimated between 25–50% (Wood 1994). The Tun Sakaran Marine Park had an average percentage of hard coral cover at the reef rim and upper slope from 11–30% in conclusion of survey and monitoring programmes over a 10-year period since 1998. (Wood et al. 2008) Coral reefs form the foundation of the economy in Semporna for local community fisheries and the tourism industry. Semporna’s fisheries products extracted from coral reef areas include collection of fish for the regional live reef fish trade and consumption in local seafood restaurants. The coral reefs of Sipadan and Mabul are increasingly popular international dive destinations, and interest in dive tourism is expanding throughout the district. The Semporna PCA was ranked as globally significant for its high biodiversity and rich mix of habitat types in a workshop of local and international experts in 2001 (Stakeholders of SSME et al. 2003). It is a priority site for Marine Industry and Tourism Zone in the Government’s Sabah Development Corridor planning document (State Government of Sabah 2007). It was included on the “A” list for recommendation for nomination as a marine natural World Heritage Site (Hillary et al. 2002). As a high priority site within the SSME, it is also a high priority site in the Coral Triangle Initiative on Coral Reefs, Fisheries and Food Security. This report documents the first comprehensive survey of the status of coral reefs in Semporna. The results will be used as baseline data for the monitoring and management of natural marine resources in Semporna PCA.

Geographic scope Between January 2008 and June 2009, surveys were carried out by WWF-Malaysia Semporna PCA team, volunteers, and local dive operators. The total reef area of Semporna PCA is approximately 7,680 km2. WWF-Malaysia surveyed 35 sites with 64 transects during this period covering all reef types across the entire Semporna PCA. The surveys were conducted first on the Southern reefs which form the barrier reef extending from Roach Reef in the west to Ligitan Reef in the east. These include: Hands Rock, Darby Bank, Alert Patches, Second Reef, Roach Reef, Friedrich Reef, Horn Reef, Ezerhzog Reef, Yoshi Point, Mabul, Kapalai, Cust Reef, Ligitan, Denawan and Si Amil. (Appendix 1) The remaining reefs are grouped as the Northern reefs and include Batuara Reef, Bum-bum, Pasalat Reef, Boheyan, Timba-timba, Mataking, Pulau Pandanan, Pom-pom, Timbun Mata and Batik. (Appendix 2) The reefs of the Tun Sakaran Marine Park and Sipadan Island were not surveyed under this project.

Materials and Methods Reef Check monitoring protocols were employed for all monitoring activities. Reef Check monitoring protocols are designed to assess baseline reef status and monitor the reef status periodically. The methods focus on the abundance of particular coral reef organisms (indicators) that best reflect the condition of the ecosystem and that are easily recognizable to the general public. This method is designed to be accessible to beginners and amateurs yet provides a regionally consistent data set which has biological significance. Global and regional indicators serve as specific measures of human impacts on coral reefs (Hodgson 2006). Reef Check, a partner of the International Coral Reef Initiative (ICRI) and Global Coral Reef Monitoring Network (GCRMN), supplies data to Reef Base and GCRMN for status reports (Hodgson & Liebeler 2002). Surveys are conducted with at least 1 pair of divers doing a full Reef Check survey in one single site. However, 2 pairs of divers are preferred to complete a single Reef Check survey in 1 single dive; 1 pair of divers conduct the survey in shallow depth, another pair of divers will conduct the survey at a mid-water depth. Standard SCUBA equipment is utilised for all surveys. Additionally, WWF-Malaysia uses underwater slate, waterproof paper with printed data sheet, pencil, eraser, pointer, 100m fibreglass measuring tape, GARMIN GPS and Semporna Waters Marine Chart. At each site a description of environmental conditions and ratings of human impacts are collected along with fish indicators, invertebrate indicators and substrate. First, fish counts up to 5 m above a 20 m by 5 m belt along a 100 m transect are counted, after the laying of the transect. Next, invertebrates are counted over four 20 m x 5 m belts along the 100 m transect and human impacts are documented. Lastly, a measure of the percentage of the substrate cover along four 20 m sections of a 100 m transect is collected. All human impact classifications are based on the regional categories of resource use and substrate. Human impact classifications include documenting evidence of blast fishing, boat and anchor damage, fishing gear, and other damages. Live coral cover is classified according to Table 1.

Category Live Coral Cover (%) Coral Cover Conditions 1 0 – 24.9 Poor 2 25 – 49.9 Fair 3 50 – 74.9 Good 4 75 – 100 Excellent

The surveys are usually done along two depth contours. Shallow surveys range from 2 – 6 m depth below chart datum (lowest low tide) and mid-water surveys range from 6 – 12 m depth. The transects are laid at a constant depth within these ranges (Hodgson 2006). (Figure 1)

Results Based on the live coral cover category level (Table 1), 11 sites are in poor condition within 0–24.9% live coral cover, 17 sites are in fair condition with 25–49.9% live coral cover, 7 sites in good condition with 50–74.9% live coral cover, and none of the surveyed sites are in excellent condition (Chart 1). However, there have been known sites with live coral cover percentage of more than 95% in Sipadan (Wood 1994).

In general, Semporna coral reefs are highly impacted from blast fishing and boat or anchor damage in some of the surveyed sites. Other damages and fish nets are the second highest impact factors with medium impacts. Trash is the least impact factor to the reefs in Semporna compared to the other factors mentioned above.

Discussion In general, the surveys indicate that most of the reefs are over-exploited and stressed by fishing activities. The reefs of the Southern and Northern islands have similar hard coral cover. There are no reefs with coral cover which falls in the excellent category, and the majority of surveyed reefs fall in the poor and fair categories with less than 50% hard coral cover. This can be partly attributed to potentially low natural coral cover or is indicative of human impacts on the reefs. Important observations from some of the indicator species merit special attention. There was no humphead wrasse (Cheilinus undulatus) observed during the surveys. The sole populations of humphead wrasse in Semporna are found on the reefs of Sipadan which are protected from fishing and destructive fishing practices by the presence of Sabah Parks and divers. Additionally, very few grouper (Serranidae) were observed during the surveys. These results indicate overfishing of these commercially and ecologically important species. During the invertebrate observations, it was found that 99% of all invertebrates were Diadema sea urchins. Diadema are also concentrated on some reefs and largely absent on others. This can indicate pressures on those reefs that promote Diadema populations or a lack of natural predators. Some areas in Semporna benefit from de facto local based management protection systems such as those enforced by dive resorts. The reefs around Mabul appear, from anecdotal evidence, to be recovering from years of blast fishing. The resorts on Mabul have been limiting bomb fishing for many years, and engaging in conservation and coral replanting activities. However, the anthropogenic pressure on the reefs has shifted from fishing activities to tourism activities which can lead to other stresses such as pollution and reef damage caused by negligent divers and snorkelers. Based on the comparison of recent and previous surveys, there appears to be some possible improvement in the condition of the reefs in some areas. For example, average coral cover in Ligitan Island was 18.7% before (Pilcher & Cabanban 2000), and the recent survey of Ligitan reefs showed that average coral cover has slight increased to 20%. Likewise, average coral cover in Mabul Island increased from 15.8% (Pilcher & Cabanban 2000) to 17.6 % (Aw 2007). Besides this, Kapalai Island with its resort that started operating since February 1998 has significant improvement of coral cover from 17.9% to 27% (Pilcher & Cabanban 2000). The improvement in condition of reefs can be expected in some areas due to the conservation efforts from the tourism sector. The conditions of reefs will further improve if more management efforts are implemented and existing regulations are better enforced. Semporna requires regular monitoring of all reef areas to inform management decisions. Monitoring should be done collaboratively with responsible management agencies, the tourism sector and local communities to follow the common vision for Semporna and to promote an interest in managing Semporna’s marine resources for sustainability. This first report provides a baseline for future monitoring and tracking of resource trends in the area.

To enhance the conservation of coral reefs in Semporna PCA, WWF-Malaysia’s projects will emphasize a collaborative, multi-sectoral approach, including government agencies, dive and tour operators, enforcement agencies, academia, NGOs, and local communities to strengthen the monitoring, patrolling and enforcement of management on coral reefs. In addition, WWF-Malaysia will continue to cultivate and increase awareness about the importance of coral reefs for livelihoods among the general public, private sector, management agencies and tourists.
