Semporna has the largest concentration of reefs within Malaysia. Semporna is unusual because of its rich mix of reef types, representing 5 major geomorphological reef types, which include a proto-atoll, an offshore seamount, fringing reefs, patch reefs, and a barrier reef formation. Such areas usually have high levels of biodiversity because of the mix of habitat types and ecosystems. There is one existing marine protected area in the district which covers 350 km2 out of the approximately 7,680 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. Previous reef status surveys from WWF-Malaysia in year 2009 found that there are no reefs with more than 75% live coral cover (those surveys did not include Sipadan or the Tun Sakaran Marine Park). Marine biologists from Malaysia, the Netherlands and the USA assessed the marine biodiversity and coral reef health during the expedition onboard MV Celebes Explorer from 29 November to 18 December 2010. The expedition was organized by WWF-Malaysia, Universiti Malaysia Sabah (UMS), Universiti Malaya (UM) and the Netherlands Centre for Biodiversity (NCB) Naturalis. The results show that Semporna rivals the top spots in the Coral Triangle in terms of coral, fish and shrimp taxa. However, the state of the reefs is worrying. Mushroom coral species (Family Fungiidae) were counted as a proxy for coral species richness. A total of 44 species were recorded from 63 sites. The mushroom coral species composition at each site was variable and depended on the reef condition. Species diversity was generally higher at reefs close to the mainland, with the highest diversity at Maiga Island (Site 41) in the Tun Sakaran Marine Park and Batik Kulambu Island (Site 53) in Darvel Bay. Both sites recorded 29 species. Semporna PCA shows two clusters of mushroom coral distributions. The first cluster comprises the barrier reef area, Sipadan and some of the outer northeastern reefs. The second cluster centers around northwestern reefs and those of Darvel Bay and the Tun Sakaran Marine Park. The total of 44 species of mushroom corals that have been recorded from this expedition surpasses other areas with very high biodiversity in the Coral Triangle such as Berau, East Kalimantan and Raja Ampat, West Papua. Both of these sites recorded 41 and 40 species of mushroom corals, respectively, and to date Semporna holds the record for the highest species diversity of this coral family. The fish surveys also found high richness. The surveys focused on reef-dwelling fish and some pelagics as encountered in the Semporna fish markets. The total reef fish diversity of Semporna recorded during the roving surveys and rotenone stations consists of 690 species belonging to 265 genera and 72 families. The total number of species recorded from market surveys was 141, of which 78 were not recorded during the roving surveys, resulting in a combined diversity of 768 species for the entire expedition. Conventional methods of predicting fish richness indicates that Semporna may reach, with further surveys, 966 species. This puts Semporna in the top 5 sites in the Coral Triangle for fish richness. iv Other taxa surveyed included reef-dwelling shrimps, coral-dwelling gall crabs, and ovidulae snails. The surveys found 104 species of shrimps, which ties with Ternate, Indonesia as the highest in the Coral Triangle. The surveys of gall crabs and ovulidae have contributed to a growing literature on these relatively unknown taxa. The algae surveys found more than 130 species. Further confirmation of specimens is being conducted at Universiti Malaya. The distribution of algae around Semporna was highly varied with high richness found at reefs throughout the study area. Many of the taxa are considered rare within the Semporna PCA. The reef status team surveyed 106 transects at 60 sites. Using a modified version of the standard Reef Check methodology, they assessed substrate cover, fish densities, invertebrate densities, and impacts. The results show that for substate cover, only 5 stations out of the 109 (5%) are found to be ‘Excellent’, 25 stations (23%) ‘Good’, 41 stations (38%) ‘Fair’ and 38 stations (35%) are at ‘Poor’ status. The fish density surveys showed low densities of nearly all indicator groups including snapper, parrotfish, humphead wrasse, and groupers. © WWF-Malaysia / Eric Madeja v Ringkasan Eksekutif Kawasan terumbu karang Semporna yang terletak di dalam kawasan Segitiga Terumbu Karang mempunyai jumlah spesies marin tertinggi yang boleh ditemui. Semporna juga adalah kawasan kepadatan terumbu karang yang paling tinggi di Malaysia. Semporna adalah unik kerana mempunyai jenis terumbu karang yang mewakili 5 jenis terumbu geomorfologi yang utama, termasuk proto-atol - sejenis gunung dasar laut, terumbu pinggir, terumbu tompokan dan pembentukan sebuah terumbu sawar. Kawasan seperti ini mempunyai biodiversiti yang tinggi kerana adanya pelbagai jenis habitat dan ekosistem. Taman Marin Tun Sakaran merupakan sebuah kawasan perlindungan marin yang meliputi keluasan 350 km2 daripada jumlah keluasan Kawasan Pemuliharaan Prioriti (Priority Conservation Area-PCA) Semporna iaitu 7,680 km2. Taman marin tersebut mempunyai 8 pulau dan merupakan kawasan perlindungan marin yang pertama di Malaysia merangkumi penduduk tempatan. Perairan Pulau Sipadan telah dicadang untuk diwartakan sebagai kawasan perlindungan marin pada pertengahan tahun 2009. Mengikut kaji selidik yang dilakukan oleh WWF-Malaysia pada tahun 2009, didapati bahawa tiada terumbu karang yang mempunyai liputan karang hidup melebihi 75%, namun kaji selidik tersebut tidak merangkumi Pulau Sipadan atau Taman Marin Tun Sakaran. Penyelidik biologi marin dari Malaysia, Belanda dan Amerika Syarikat telah membuat kajian ke atas biodiversiti marin dan kesihatan terumbu karang dalam sebuah ekspedisi pelayaran di atas kapal MV Celebes Explorer dari 29 November hingga 18 Disember 2010. Ekspedisi ini dianjurkan oleh WWF-Malaysia, Universiti Malaysia Sabah (UMS), Universiti Malaya (UM) dan Netherlands Centre for Biodiversity (NCB) Naturalis. Hasil kajian menunjukkan bahawa Semporna mempunyai kepelbagaian hidupan marin yang tinggi dan setaraf dengan kawasan lain dalam Kawasan Segitiga Terumbu Karang terutamanya untuk taksa batu karang, ikan dan udang. Namun, status kesihatan terumbu karang adalah dilaporkan dalam keadaan yang membimbangkan. Spesies batu karang dari Famili Fungiidae telah digunakan sebagai proksi untuk kepelbagaian spesies batu karang secara keseluruhan. Sebanyak 44 spesies direkodkan daripada 63 tapak kajian. Komposisi spesies batu karang Fungiidae ini adalah berbeza di setiap tapak kajian dan bergantung kepada keadaan terumbu karang di tapak tersebut. Secara umumnya, kepelbagaian spesies adalah lebih tinggi di kawasan terumbu karang berhampiran tanah besar dengan kepelbagaian paling tinggi dicatatkan di Pulau Maiga (Tapak kajian 41) di Taman Marin Tun Sakaran dan Pulau Batik Kulambu (Tapak kajian 53) di Teluk Darvel. Kedua-dua tapak kajian merekodkan sebanyak 29 spesies batu karang Famili Fungiidae. Kawasan Pemuliharaan Prioriti Semporna menunjukkan taburan dua (2) kelompok batu karang Famili Fungiidae ini. Kelompok pertama ditemui di kawasan terumbu sawar, tebing karang Pulau Sipadan dan kawasan terumbu karang di arah timur laut. Kelompok kedua pula didapati di sekitar kawasan barat laut dan juga di Teluk Darvel dan Taman Marin Tun Sakaran. Jumlah 44 spesies terumbu karang Famili Fungiidae yang direkodkan sepanjang ekspedisi ini merupakan kepelbagaian tertinggi jika dibandingkan dengan kawasan lain di dalam kawasan Segitiga Terumbu Karang seperti Berau, Kalimantan Timur dan Raja Ampat, Papua Barat. Kedua-dua kawasan tersebut merekodkan sebanyak 41 dan 40 spesies terumbu karang Famili Fungiidae. Setakat ini Semporna memegang rekod untuk jumlah spesies yang tertinggi untuk batu karang Famili ini. vi Kajian ke atas ikan juga mencatatkan jumlah kepelbagaian yang tinggi. Kaji selidik yang dijalankan tertumpu kepada jenis ikan terumbu karang dan beberapa pelagik yang ditemui di pasar ikan Semporna. Jumlah biodiversiti ikan terumbu karang yang didapati di Semporna dengan menggunakan kaedah ‘roving surveys’ dan ‘rotenone stations’ adalah 690 spesies yang terdiri daripada 265 genera dan 72 famili. Jumlah spesies yang direkodkan daripada kaji selidik yang dijalankan di pasar ikan adalah sebanyak 141 dimana antaranya 78 jenis yang tidak ditemui semasa ‘roving surveys’. Ini menjadikan jumlah keseluruhan kepelbagaian ikan dicatatkan di sepanjang ekspedisi adalah sebanyak 768 spesies. Kaedah konventional dalam mengganggarkan kepelbagaian jenis ikan di Semporna menunjukkan kemungkinan bagi jumlah tersebut untuk mencapai sehingga 966 spesies ikan. Dengan itu, Semporna dikenalpasti sebagai salah satu dari 5 kawasan kepelbagaian ikan tertinggi di Kawasan Segitiga Terumbu Karang. Taksa lain yang dikaji selidik termasuk udang, ketam ‘gall’ dan siput ovidulae terumbu karang. Hasik kaji selidik menemui 104 jenis udang, iaitu jumlah yang sama ditemui di Ternate, Indonesia iaitu jumlah tertinggi di dalam Kawasan Segitiga Terumbu Karang. Kajian keatas ketam ‘gall’ dan siput ovidulae terumbu karang telah menambahkan pengetahuan ke atas taksa yang masih belum diketahui secara luas ini. Kajian terhadap alga mencatatkan jumlah sebanyak 130 spesies. Pengesahan lanjutan sedang dijalankan di Universiti Malaya. Taburan spesies alga di sekitar Semporna adalah amat pelbagai dan tinggi di terumbu karang di kawasan kajian. Kebanyakan dari taksa adalah dianggap jarang ditemui di kawasan pemuliharaan marin Semporna. Kumpulan penyelidik yang membuat kajian ke atas status terumbu karang telah membuat kajian untuk 106 transek di 60 tapak kajian. Dengan menggunakan kaedah ReefCheck yang diubahsuai, kajian ke atas litupan substrat, densiti ikan, densiti invertebrat, dan impak ke atas terumbu karang telah dijalankan. Hasil kajian mendapati untuk litupan substrat hanya 5 stesen daripada jumlah keseluruhan 109 stesen (5%) adalah dalam keadaan “Amat Baik”, 25 stesen (23%) mencatatkan keadaan “Baik”, 41 stesen (38%) dalam keadaan “Memuaskan” dan 38 stesen (35%) adalah dalam keadaan “Tidak Baik”. Hasil kajian ke atas densiti ikan menunjukkan densiti yang rendah untuk hampir kesemua kumpulan ikan penunjuk spesies iaitu ikan jenahak, ketarap, bayan-bayan dan kerapu. vii 1. Introduction At the southeast corner of the Malaysian Bornean state of Sabah lies the Semporna district and Semporna town. The district is bounded on the west by the districts of Kunak and Tawau. To the north and south lie inlets of the Sulawesi Sea, Darvel Bay and Cowie Bay respectively. Semporna town, at the eastern tip of the Semporna Peninsula is the main trading town for more than 50 islands which lie east of the peninsula. The Sulawesi Sea is part of the Sulu-Sulawesi Marine Ecoregion and the ecological definition of the Coral Triangle. Semporna The Semporna reef complex is located within the Coral Triangle region, where the highest numbers of marine species are found. Semporna has the largest concentration of reefs within Malaysia. Semporna is unusual because of its rich mix of reef types, representing 5 major geomorphological reef types, which include a proto-atoll, an offshore seamount, fringing reefs, patch reefs, and a barrier reef formation. Such areas usually have high levels of biodiversity because of the mix of habitat types and ecosystems. There is one existing marine protected area in the district which covers 350 km2 out of the approximately 7,680 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. Previous reef status surveys from WWF-Malaysia found that there are no reefs with more than 75% live coral cover (those surveys did not include Sipadan or the Tun Sakaran Marine Park). Marine biologists from Malaysia, the Netherlands and the USA assessed the marine biodiversity and coral reef health during the expedition onboard MV Celebes Explorer from 1 29 November to 18 December 2010. The expedition was organized by WWF-Malaysia, Universiti Malaysia Sabah (UMS), Universiti Malaya (UM) and the Netherlands Centre for Biodiversity (NCB) Naturalis. The expedition was launched on the 29th of November 2009 by Mr. Norsih Nusuri, the Assistant District Officer of Semporna. 1.1 Objectives • Assessment of coral reef biodiversity including reef fish and associated reef fauna richness The biodiversity on the reef can be compared between different sites (within Semporna), as well as with other areas within the Coral Triangle (e.g. Berau, Raja Ampat, Ternate, etc.), and Malaysia in particular. There is no definitive count of the species richness across a wide range of habitats in Semporna. This is important to determine the areas of high potential for diving tourism, conservation and other economic activities in the future. • Assessment of coral reef status and reef population health A ‘snapshot’ of the reef health will be assessed for each site at two depths using a modified Reef Check methodology and reef profiling. This will complement the surveys which were completed in 2008 (Ho and Kassem 2009) which show that the overall condition of Semporna’s reefs is in the “poor” and “fair” categories. Recurring surveys are important to determine a trend of reef status in the area. • Conservation and outreach Establish the value of the Semporna area for diving tourism in combination with coral reef conservation, based on its reef status, which includes information on species richness and the occurrence of rare and endemic species. The Semporna Priority Conservation Area is listed as globally-outstanding for its biodiversity in the Tri-national Conservation Plan of the SuluSulawesi Marine Ecoregion (SSME). In addition, the SSME is one of the priority seascapes of the Coral Triangle Initiative which was signed by the Heads of State of the 6 Coral Triangle counties in 2009. 1.2 Methodology There were several concurrent surveys conducted during the assessment of coral reefs. Each survey employed slightly different methodologies to ensure compatibility and comparability with previous surveys in Semporna and throughout the Coral Triangle. A small team of international and local scientists conducted the entire survey. Each team made 2-3 survey dives or outings per day throughout the Semporna reef complex. The sites were selected using nautical maps, satellite images and GPS. The survey was conducted from the liveaboard boat, MV Celebes Explorer (based in Semporna). Coral reef biodiversity – An inventory of corals, fishes and associated reef fauna species was made during SCUBA dives using the Roving Diver technique. Species records were used in a species richness estimation analysis for species presence-absence comparisons (see Hoeksema 2004, Hoeksema & Koh, 2009). Specimens of particular scientific interest were collected for the reference collections of the participating institutes for further identification (Borneo Marine Research Institute of Universiti Malaysia Sabah at Kota Kinabalu, Netherlands Centre for Biodiversity Naturalis at Leiden). In addition, specimens were collected for molecular phylogenetic (evolutionary) comparisons and phylogeographic studies on connectivity. 2 Coral reef status – A single ‘snapshot’ of Semporna’s coral reef health was established using modified and supplemented Reef Check (Hodgson et al., 2006) and Asean Australian methods (English et al., 1997). In addition to this, reef profiling was conducted at all sites and random swims and quadrat photos were made at shallow reefs or reef flats. Most sites were also supplemented with underwater video transects. By being based on a liveaboard boat, the teams were able to make several dives per day. The biodiversity team used the WWF-Malaysia catamaran Kahumbu, while the reef status team used the diving skiff of the MV Celebes Explorer. The two teams would dive in similar sites 2 to 3 times per day while the MV Celebes Explorer moved between sites. Usually 2 dives were made in the morning and 1 or 2 dives were made in the afternoon and early evening. In the evenings and between dives, the biodiversity team used the MV Celebes Explorer upper deck to process collected specimens. In the evenings both teams focused on data entry. Permits for collections were obtained from Department of Fisheries Sabah. Permits for data collection in the Sabah Parks’ sites were obtained from Sabah Parks. All expedition participants from overseas obtained research permits from the Economic Planning Unit and research passes from the Department of Immigration in Sabah. 1.3 Expedition Dive sites and GPS

Biodiversity surveys 2.1 Introduction Hereby, we present the preliminary results of the biodiversity survey that was part of the Semporna Marine Ecological Expedition (SMEE) 2010. The outcome of the expedition will help to see which areas within the Semporna region are relatively rich in species, some of which are unique or rare. With regard to physical conditions, a major distinction can be made between the predominantly oceanic, wave-exposed reefs in the south and the mostly sheltered reefs in the north, especially those in Darvel Bay. This difference is also reflected in the species composition and richness of some taxa, like for instance some coral and fish families. Besides their application in conservation efforts, the results will be worked out and published in scientific journals. So far five short papers have been published and a sixth is accepted for publication. We aim to make © WWF-Malaysia / Eric Madeja those papers available through open access and to become freely available to the public. We hope that this shared knowledge will help to promote the Semporna region as a dive destination and that this will help to stop the use of destructive fishing methods. We are indebted to WWF-Malaysia and WWF-Netherlands for organizing this expedition, and to their sponsors for the financial support. We are grateful to our colleagues (of WWF, the reef status team, and the biodiversity team), Eric Madeja of Treasure Images Sdn Bhd, and the crew of MV Celebes Explorer for the cooperation. 8 2.2 Hard Corals (Families Fungiidae, Agariciidae and Euphyllidae) Zarinah Waheed and Bert W. Hoeksema Netherlands Centre for Biodiversity - Naturalis, PO Box 9517, 2300 RA Leiden, The Netherlands E-mail: Zarinah.Waheed@ncbnaturalis.nl, Bert.Hoeksema@ncbnaturalis.nl The coral families Fungiidae, Agariciidae and Euphylliidae were chosen for the hard coral biodiversity study. These three families have a wide geographical distribution and are found in various reef habitats. Reliable data can be obtained on their species presence or absence by per reef area surveyed. It would be unrealistic to work with absolute maximum numbers of all coral species as this would decrease the precision of the data. Fungiidae Mushroom corals account for 10% of all reef-dwelling hard coral species. They are taxonomically well studied and are easily identified in the field. Areas with high richness of mushroom coral species usually have high richness of other corals as well. Mushroom corals belong to the Indo-Pacific family Fungiidae and has a total of 11 genera: Fungia (26 species), Heliofungia (1 species), Ctenactis (3 species), Herpolitha (1 species), Polyphyllia (2 species), Sandalolitha (3 species), Zoopilus (1 species), Halomitra (2 species), Cantharellus (3 species), Lithophyllon (3 species) and Podabacia (4 species). The genus Fungia is divided into seven subgenera (Hoeksema, 1989). However, a recent study by Gittenberger et al. (2011) suggested a revision in the classification of this family based on their molecular analyses. A total of 44 species of mushroom corals have been recorded from 63 sites during this expedition (Appendix 1). Data on the presence and absence of coral species per site were used for species richness analyses. The species richness estimators were calculated using the programme EstimateS (Colwell, 2009), in which the sample order is randomized and the values are averaged. The mean and standard deviation of species richness at each sample number are calculated and the curves are extrapolated to estimate the total species richness in an area (Magurran, 2004). The species accumulation curves show the rate at which other species are found and more sampling will uncover more species, making the accumulation curves arch upwards (Magurran, 2004). When the curves flatten out and reach an asymptote with minimal standard deviation (close to 0), additional species is not discovered. The present species accumulation curves show that the estimated species numbers (ICE, Chao 2) reaches the observed species number very closely with an error of less than one. In theory, additional sampling may reveal one more species (Fig. 1). The mushroom coral species composition at each site was variable and depended on the reef condition. Species diversity was generally higher at reefs close to the mainland, with the highest diversity at Maiga Island (Site 41) in the Tun Sakaran Marine Park and Batik Kulambu Island (Site 53) in Darvel Bay. Both sites recorded 29 species. 9 Fig. 1. Species accumulation curves indicating numbers (and standard deviations) of mushroom corals observed at Semporna from 63 dives (n=44). For statistics see Colwell (2009). Based on the species composition of mushroom corals, a cluster analysis was carried out to determine the similarity or differences in species composition among the sites. Several methods were used but the Ward’s minimum variance clustering method showed the clearest pattern. The sites were clustered into two main areas (Fig. 2 and 3), and seem to be separated by a line from Semporna in an East-northeast direction. The first area is from the outer reefs of the northeast to the south of Semporna, which includes the barrier reef formation and the oceanic island of Sipadan. These reefs are more exposed to the oceanic elements as compared to the first area. These reefs are not very well described, with the exception of Sipadan Island (Wood, 1987; Wood and Tan, 1987; Wood, 1994) and Mabul Island (Aw, 2009). The second area is towards the north of Semporna including the islands in Darvel Bay and most of the reef sites in the Tun Sakaran Marine Park. The reefs in the Park are composed of fringing reefs, atolls or ring reefs, platform reefs and reefs with low islands (see Wood, 1987 for detailed descriptions of the reef geomorphology within the park area). The reefs in Darvel Bay are also composed of fringing and patch reefs, however, unlike the reefs in the park area, these reefs are characterized by brown turbid waters with high humic content and sheltered conditions (Ditlev, 2003), especially towards the inner part of the bay. A comparison of the coral species composition of Semporna with other studied localities in the region shows that Semporna is within the cluster representing the Coral Triangle (Fig. 4). The total of 44 species of mushroom corals that have been recorded from this expedition 10 surpasses other areas with very high biodiversity in the Coral Triangle such as Berau, East Kalimantan and Raja Ampat, West Papua. Both of these sites recorded 41 and 40 species of mushroom corals, respectively, and to date Semporna holds the record for the highest species diversity of this coral family (Fig. 5). Some species have widespread distributions and can be considered common, such as Fungia (V.) repanda, Fungia (W.) granulosa, Herpolitha limax and Podabacia crustacea. Other species that were encountered at only few sites are rare and may be limited to a certain environments based on the reef type or preference, such as Fungia (C.) cyclolites, Podabacia sinai, Sandalolitha sp., Fungia (C.) hexagonalis, and Fungia (P.) taiwanensis (Plate 1). Some rare coral species only known from a few localities in the Coral Triangle, such as Lithophyllon ranjithi and Halomitra clavator, were also recorded (Plate 2). Previous studies documenting the species diversity of hard corals around Semporna are listed in Table 1. A comparison of the species diversity of mushroom corals from these previous studies and this present report is shown in Appendix 2. The previous studies did not record as many species as the recent expedition. The reason is two-fold: 1) it is difficult to identify and document all species (> 500) of hard corals on the reef as the focus is too broad, 2) these studies were carried out to determine the status of the reefs rather than concentrate solely on the species count of corals. For these reasons, rare and inconspicuous species were more easily overlooked in the previous studies. Table 1.

Other rare mushroom coral species worldwide that were recorded in Semporna 16 Agariciidae Corals of the family Agariciidae are represented by five genera in the Indo-Pacific: Leptoseris (15 species), Pavona (13 species), Gardineroseris (1 species), Coeloseris (1 species) and Pachyseris (5 species) (Veron and Pichon, 1979). In general, agariciid corals are found in a variety of reef habitats but Leptoseris species are more common in deeper reef environments. The growth forms of these corals may be massive (boulder-shaped) or laminar (plate-like). In Semporna, a total of 31 species of agariciid corals was documented from 59 dives (Appendix 3). The species accumulation curves show that the estimated species numbers (ICE, Chao 2) reach the observed species number asymptotically. Therefore sampling effort has been sufficient and additional sampling would not have resulted in more species (Fig. 6). Reefs with highest species diversity were generally found near the coast, with the exception of a few offshore reef sites such as Sipadan and Mataking Islands. The highest diversity of agariciid corals was recorded at Sibuan Island (Site 44). Fig. 6. Species accumulation curves indicating numbers (and standard deviations) of agariciid corals observed at Semporna during 59 dives (n=31). For statistics see Colwell (2009). Based on the species composition of agariciid corals, the sites were also clustered to two main areas (Fig. 7 and 8). Similar to the mushroom corals, the two distinct clusters seem to be separated by a similar line from Semporna in an East-northeast direction. 17 Some species are common and were found at more than 40 sites, such as Pachyseris speciosa, Pavona varians, Leptoseris cf. scabra, Gardineroseris planulata and Pavona explanulata (Plate 3). Leptoseris scabra is thought to be one of the most common Leptoseris species. However upon inspection of the type specimens from Hawaii, deposited in the Smithsonian Institution (USNM 20886 and USNM 20885), we found that the type specimens are small, with smaller corallites and finer septocostae than the specimens we found in Semporna. This variation could be related to the different locality or habitat type. On the other hand, it could also be a different species altogether. For these reasons the specimens were provisionally identified as Leptoseris cf. scabra until further examination can prove their identity. Rare species or species that were found at less than five sites are Leptoseris amitoriensis, Leptoseris solida, Leptoseris sp. and Pavona minuta (Plate 4). Leptoseris sp. is possibly Leptoseris fragilis and requires further examination. The comparison of the presently observed species diversity of agariciid corals with those of earlier studies in Semporna (Appendix 4) shows that the current expedition recorded more species. The reasons for this are similar to those mentioned previously under the mushroom coral section. 18 Fig. 7.

Rare or uncommon agariciid corals. These corals were encountered at less than five sites in Semporna 22 Euphylliidae Coral family Euphylliidae is composed of five genera, all occurring in the Indo-Pacific, namely Euphyllia (8 species), Plerogyra (6 species), Physogyra (1 species), Catalaphyllia (1 species) and Nemenzophyllia (1 species). They are characterized by large-sized corallites with conspicuous tentacles that are usually extended all the time. The tentacles have the form of long tubes, bubble-like grapes, anchor or hammer-shaped, or even fleshy mantles, depending on the species. Generally, euphylliid corals can be found in various reef environments but some species have a preference for sheltered and turbid environments. Out of the total of 17 species of currently known euphylliid corals, 15 species were recorded during 59 dives in Semporna (Appendix 5). Similar to the agariciid corals, the species accumulation curves show that the estimated species numbers (ICE, Chao 2) reach the observed species number. Hence additional sampling would not have resulted in additional species (Fig. 9). The species diversity of euphylliid corals was highest at the coastal reefs rather than the oceanic reefs, as observed for the Agariciidae. The highest diversity was recorded at Timbum Mata Island (Site 48), while the lowest was at Mabul and Sipadan Islands (Sites 12 and 59, respectively). Fig. 9. Species accumulation curves indicating numbers (and standard deviations) of bubble corals observed at Semporna during 59 dives (n=15). For statistics see Colwell (2009). 23 Based on the cluster analysis, there was no distinct pattern in the species composition of euphylliid corals that could distinguish between the reefs of the area (Fig. 10 and 11). However, there were species that were found exclusively in the nearshore/coastal reefs such as Nemenzophyllia turbida, Euphyllia paradivisa, Plerogyra diabolotus and Plerogyra cauliformis (Plate 5). Frequently encountered (>40 sites) euphylliid coral species include Plerogyra sinuosa, Physogyra lichtensteini, Euphyllia glabrescens, Euphyllia ancora, and Euphyllia divisa. These species are also common in the area (Plate 6) Rare or uncommon euphylliid coral species are Euphyllia cristata and Plerogyra cauliformis and these two species were only encountered four times each and at different sites (Plate 7). The three new euphylliid coral species that were first discovered in Darvel Bay and described by Ditlev (2003) were also found during the expedition. Thus far these coral species have only been reported from this locality. Similar to the mushroom corals and agariciid corals, the species number of euphylliid corals recorded from this expedition is higher compared to those of the previous studies (Appendix 6). 24 Fig. 10.

The reef fish surveyed were restricted to a maximum depth of 40m for safety, while the pelagic and open water species were restricted to those observed in markets. The results of this study are likely to highlight the great diversity of fishes in the area and thus demonstrate the importance of further protection for marine reserves such as Sipadan Island, and marine parks such as the Tun Sakaran Marine Park. Methods Fish surveys Fish diversity was estimated using (1) roving surveys, (2) rotenone stations, and (3) fish market surveys. Roving surveys were conducted by a single observer (K. Carpenter or B. Stockwell) at a total of 37 sites. Surveys were each a total of 60 minutes and began at the base of the reef slope (3020m) and ended along the reef flat, in which the observer recorded all species encountered. Fish abundances were recorded using a log10 scale. The roving surveys were supplemented using rotenone (an ichthyocide) at four stations (36, 46, 50, 54). Rotenone powder was mixed with liquid detergent and seawater to create an emulsion, which was applied to small coral heads at various depths. Divers waited 5 minutes before collecting specimens. The purpose of ichthyocides is to collect highly cryptic species (i.e. eels and gobies) that are not observed during the roving surveys. Market surveys were conducted before the beginning of the expedition (29 November) and during rest days (6 and 14 December) at the Semporna fish market. Data Analysis Multivariate analyses of species assemblages were carried out using the computer software package PRIMER (www.primer-e.com) (Clarke and Warwick 2001). Data were transformed to species presence/absence to further minimize the potential effects of fishing and reserve protection on fish species assemblage patterns. Degrees of similarity between sites based on species composition were examined first by constructing a resemblance matrix using Bray-Curtis similarity. [Note that BrayCurtis similarity is equivalent to Sorenson’s similarity when used on presence/absence data. Furthermore, ‘shared absences’ between samples have no effect on the computation of Bray-Curtis similarity coefficients (Clarke and Warwick 2001)]. Hierarchical clusters of sites (agglomerative) were then generated from the Bray-Curtis resemblance matrix. A series of ‘similarity profile’ (SIMPROF) tests in PRIMER were used to identify statistically-significant clusters of sites. To highlight geographic patterns, the groupings of sites indicated by hierarchical clustering were illustrated on maps. Results The total reef fish diversity of Semporna recorded during the roving surveys and rotenone stations consists of 690 species belonging to 265 genera and 72 families (Appendix 1). The total number of 43 species recorded from market surveys was 141 (Appendix 2), of which 78 were not recorded during the roving surveys, resulting in a combined diversity of 768 species for the entire expedition. General faunal composition The most abundant families in terms of number of species are damselfishes (Pomacentridae), wrasses (Labridae), gobies (Gobiidae), groupers/basslets (Serranidae), cardinalfishes (Apogonidae), butterflyfishes (Chaetodontidae), surgeonfishes (Acanthuridae), parrotfishes (Scaridae), snappers (Lutjanidae), and angelfishes (Pomacanthidae). These 10 families collectively account for 66% of the total reef fish fauna (Fig. 1). Total diversity per site varied greatly from 74 to 270 (Table 1). The total number of species on a reef is usually a product of food availability, shelter, and the diversity of substrata (Allen 2002). Thus the sheltered sites (i.e. 4, 5, 40, 43, 47, and 56) with low coral cover were among the poorest sites in terms of diversity. The top ten richest sites (Table 2) had some of the highest coral cover and habitat complexity. However, this list also highlights the importance of fishing, since the top five sites are also closed to fishing. 100 92 90 84 80 # of species 70 60 54 50 41 40 38 40 31 20 18 Lutjanidae Pomacanthidae 25 30 20 10 0 Scaridae Acanthuridae Chaetodontidae Apogonidae Serranidae Gobiidae Labridae Pomacentridae Figure 1.

However, according to Lieske and Myers (2002) this fish is restricted to Western Australia. This is either a disjunct range extension or a possibly undescribed species. Further samples need to be collected to confirm either of these conclusions. Fig. 1. Marble inscription at the Semporna fish market and photograph of Siganus trispilos at Barracuda Pt., Sipadan Island. Coral Fish Diversity Index Given the unlikely event that all reef fish species are encountered during a roving survey Allen (1998) devised a method for estimating total reef fish diversity from six key families: Chaetodontidae, Pomacanthidae, Pomacentridae, Labridae, Scaridae, and Acnthuridae. The total number of species in these six families is used to obtain the Coral Fish Diversity Index (CFDI) for either a single site (e.g. Mabul Is.) or restricted geographic areas such as the reefs around Semporna. For areas less than 2,000 km2 the equation: x = (3.39 x CFDI) – 20.595 (d.f. = 18; R2 = 0.96; P > 0.0001) was used to estimate total reef fish diversity. An overall CFDI value of 291 was generated from the 37 roving surveys, resulting in an estimated total reef fish diversity of 966. These values put the reefs of Semporna among the top five most diverse sites surveyed by the Rapid Assessment Program (RAP) of Conservation International (Table 3). Table 3.

The hierarchical clustering of the 37 sites using data on presence/absence of species suggested groups that reflected reef exposure (Fig. 2, 3). The first division (45 % similarity) splits the sites into exposed and sheltered reefs, while the SIMPROV tests further split these clustering in smaller subsets depending on geographic location (e.g. east vs. south sheltered reefs) (Fig. 2). This division was likely a result of higher mean CFDI values for exposed (90.7) vs. sheltered (61.3) reefs. The seven clusters generated by SIMPROV suggest significant differences in species assemblages within exposed and sheltered reefs of Semporna (Figure 2). However, only three of these assemblage groupings (2 in Tun Sakaran MP and 1 in Sipadan Is.) are located in reefs closed to fishing (Fig. 3). 20 Habitat S Exposed Oceanic W Exposed Inner Sheltered E Sheltered S Sheltered Mid.

Summary • • • • • • • A list of fish species was compiled for 37 roving census sites, 4 rotenone sites, and fish market surveys. The survey involved 41 hours of scuba diving to a maximum depth of 33m. The reefs around Semporna are among the world’s richest in terms of reef fish diversity, consisting of 768 observed species and an estimated total diversity of 966 species. Damselfishes (Pomacentridae), wrasses (Labridae), and gobies (Gobiidae) are the dominant families in terms of species numbers. Species numbers at roving census sites ranged from 74 to 270, with an average of 122.2. Although diversity was high, there was evidence of overfishing. Groupers were rare at most sites, while Napoleon wrasses were only seen at 3 sites. In addition to overfishing, incidences of blast fishing were heard frequently during surveys on the inshore reefs. The areas with the highest diversity and density were in areas closed to fishing. Seven distinct species assemblages were identified through cluster analyses, only 3 of which are located within marine reserves. 48 Recommendations • • • Given the devastating and long term effects of blast fishing, more effort should be allocated to stopping this fishing technique within the reefs of Semporna. Given the high diversity and fish biomass in no-take marine reserves such as Sipadan Is., more of such reserves should be established to improve and protect fish stocks. Given that 7 distinct species assemblages were discovered, and only 3 are within marine reserves, it is recommended that a network of no-take marine reserves be established in the south to include these remaining species assemblages.

Fransen Netherlands Centre for Biodiversity - Naturalis, PO Box 9517, 2300 RA Leiden, The Netherlands. E-mail: Charles.Fransen@ncbnaturalis.nl The most diverse subfamily of marine shrimps in the palaemonoids is the Pontoniinae, comprising over 600 species (De Grave and Fransen, 2011) with around 430 recorded from the Indo-Pacific. Most species are living in association with other organisms. Only few records of these shrimps from the Semporna area are known in the scientific literature. Holthuis (1950, 1952), in his monographs on the Palaemoninae and Pontoniinae of the Siboga and Snellius Expeditions, recorded a few species from the Sulu Archipelago near the Semporna area. Shrimps were photographed on their host before collecting. During 60 dives a total of 360 samples were collected comprising about 550 specimens. Preliminary identification of the material yielded ca. 104 species (Table 1). In genera like Periclimenes and Periclimenaeus, identification to species level awaits further morphological study of the specimens. New species in these genera are expected. The number of palaemonoid species is rather high in comparison with most other localities visited within the Coral Triangle (Fransen, 2007; Hoeksema, 2007): East Kalimantan (2003: ca. 90 species), Cebu (1999: ca. 87 species), Sulawesi (1994: ca. 80 species), Ambon (1996: ca. 90 species), Bali (2001: ca. 90 species), Ternate (2009: ca. 104), and Raja Ampat (2007: ca. 77 species), and distinctly higher than the localities outside this area: Seychelles (1992: 57 species), Pulau Seribu (2005: 60 species). Table 2 summarizes the number of species per host group for the areas studied over the years. Table 1.

Currently, the Cryptochiridae include 46 extant species (20 genera), of which two are deep-water species. Gall crabs can probably be found worldwide, wherever scleractinian corals occur. Many reefs still need to be sampled for gall crabs, and doing so from the host perspective (sampling as many different host corals as possible) yields many new associations. The females of some species live within enclosed ‘galls’, completely encompassing the crab, in which it remains for the remainder of its life. Other gall crab species live in an indentation or pit in the coral, which they can leave if needed. The males are far smaller than the females, and sometimes encountered wandering freely on top of the coral. During the fieldwork carried out in Semporna, stony corals and the associated gall crabs were sampled during 60 dives. The goal was to obtain as many different species of gall crabs from a wide range of coral hosts from the Semporna region. Gall crabs where collected from > 100 different coral hosts, belonging to 33 genera and nine coral families (Table 1, Fig. 1). A total of 213 samples were collected, and for a number of specimens identification to species level awaits microscopic study (Appendix 1). Compared to the Ternate area (Halmahera, Indonesia), Semporna appears to have a similar diversity of coral gall crabs, which is not surprising given the similarities between the coral assemblages in the two areas. For the gall crabs identification to species level awaits further morphological study of the specimens, after which a better comparison can be made. One gall crab species was found in Semporna which was not encountered during previous expeditions (Neotroglocarcinus cf. hongkongensis from the coral Turbinaria peltata). In Semporna this coral was more intensively searched for associated gall crabs than in Ternate. Fig. 1.

E-mail: Bastian.Reijnen@ncbnaturalis.nl Introduction Ovulidae are gastropod molluscs which are primarily associated with Octocorallia but can also be found on antipatharians (black corals). Ovulids are globally distributed in tropical and temperate seas, but their greatest diversity is found on reefs in the Indo-Pacific. Currently over 200 species are described from both shallow and deep water reefs (Lorenz and Fehse, 2009). Little is known of the Malaysian ovulid fauna, particularly focussing on eastern Borneo. Lorenz and Fehse (2009) e.g. show several in situ photographs of Malaysian ovulids and George and George (1987) have a record of Ovula ovum (Linnaeus, 1758) from the outer reef of Mantabuan Isl., but scientific data on the diversity and distribution of Malaysian Ovulidae remains scarce. Scientific literature on the Octocorallia diversity around Borneo is also limited. George and George (1987) have made an inventory of the gorgonians and alcyonaceans at the Bodgaya Islands, which is now the Tun Sakaran Marine Park, and Sipadan Isl. In their inventory they mention 58 different species or species groups. An additional record is by Bayer (1950) who described a new Corallium species (Corallium borneënse) from north Si Amil Isl. For this report we focussed on the interactions between the Octocorallia and the Ovulidae. Therefore we do not provide a complete overview of the Octocorallia at Semporna, but give an overview of the observed interactions between octocorals and ovulids. Discrepancies between the George and George (1987) paper can therefore be observed. Identifying Octocorallia is troublesome, most characters are poorly defined and even specialists cannot always positively identify genera or species. As a result only one paper describing the interactions between both Ovulidae and Octocorallia from the Indo-Pacific is known e.g. Schiaparelli et al. (2005). Therein no specimens from Malaysia were included, therefore this is the first overview specifically on the association between octocorals and their associate ovulids from Malaysian Borneo. Material and Methods Gorgonians and soft corals were meticulously searched for ovulid snails, while using SCUBA equipment. Upon encounter in situ photographs were made to record the morphology and colour (patterns) of both the host and symbiont (see Fig. 1). The ovulid snail including a tissue sample of its host species was collected and stored on 80% ethanol to preserve it for closer examination. Identifications of the Ovulidae were made with the help of a dissecting microscope and reference literature from Cate (1973) and Lorenz and Fehse, (2009). The nomenclature as used by the latter reference was used for this report. For the octocorallia, microscopy slides of the sclerites (internal calcareous parts) had to be made for identification purposes. A chlorine solution (common bleach) was used to dissolve 76 the tissue. The remaining residue was washed 5 times with tap water followed by 5 washing steps with distilled water. Sclerites were embedded in euparal to enable visualisation and identification under a stereomicroscope. Results In total 30 species of Ovulidae were found divided over 17 genera, excluding a single representative from the family Pediculariidae. Formerly Pediculariidae were considered to belong to the family Ovulidae but recent insights (Lorenz and Fehse, 2009) placed the Pedicularia in a separate family (Table 1). In total over 220 individuals of Ovulidae were observed and collected. For the Octocorallia, a total of 102 specimens were preserved for further identification. Closer identification revealed at least 48 different species(groups) of which not all could be provided with a species name (Table 2). New records of genera for the Semporna region are, compared to George and George (1987): Acanthogorgia, Annella, Bebryce, Chironephthya, Ctenocella, Paracis, Solenocaulon, Studeriotes, Villogorgia and Viminella.

This data indicates that the most diverse reefs, were south of Semporna. Darvel bay and its surroundings (Islands and reefs NW of Boheydulang Isl.) proved to be less diverse. In general Octocorallia prefer nutrient rich, turbid waters. Since the Darvel Bay area is murkier and less prone to currents, the number of Octocorallia and their diversity was lower, resulting in a lower number of symbiotic Ovulidae. Ovulid-wise the most diverse spot was Kapalai, SE of Mabul. In total seven different ovulids were observed during a single dive. 78 Table 3.

Draisma Institute of Ocean and Earth Sciences – University of Malaya, Kuala Lumpur, Malaysia. E-mail: sgadraai@hotmail.com Introduction Macroalgae or seaweeds (rumpai laut in Malay language) are macroscopic algae. They have representatives on different branches of the Tree of Life, namely the green algae (Chlorophyta), the red algae (Rhodophyta), and the brown algae (Phaeophyceae). The bluegreen algae (Cyanophyta) are photosynthetic bacteria and also have macroscopic representatives. The temperate seas around Japan and southern Australia harbor the highest seaweed diversity. However, some seaweed genera have their highest diversity in the tropics, e.g., the green algal genera Caulerpa and Halimeda, and the brown algal genera Padina, Sargassum and Turbinaria. These taxa can sometimes form large dominant stands on coral reefs. Seaweeds need a hard substrate to attach themselves to by means of a holdfast structure. They lack roots for anchoring in the sand. Notable exceptions are some species of Caulerpa and Halimeda that can be found on sand. Seaweeds are at the base of the food chain and are grazed by herbivores (fish, snails). Algae developed different strategies against grazing. Many slow growing algae produce calcium carbonate (limestone) as a defense against herbivory. The strategy of filamentous algae is to grow very fast so that grazers cannot keep up with them. A healthy coral reef habitat generally is dominated by massive corals and crustose coralline algae. These calcareous red algae cement the corals together to build the reef framework. Fleshy algae are removed by abundant herbivores. Some corals are inhibited by elevated nutrient levels and crustose coralline algae may become the dominant group. The reef may become dominated by low growing and turf algae in cases where grazing activity decreases. Decreased grazing activity in combination with elevated nutrient levels may result in the dominance of frondose macroalgae (Littler et al. 2009: Smithsonian Contributions to the Marine Sciences 38: 401-414). Seagrasses are not algae but flowering plants (Magnoliophyta) that have “returned” to the sea. They have a root system and can form extensive seagrass bed habitats next to coral reefs. Methodology During the Semporna Marine Ecological Expedition the seaweed diversity of the reefs around Semporna was investigated by Stefano Draisma. Draisma made SCUBA dives of approximately sixty minutes each at 57 sites (Fig. 1) and scored the presence or absence of seaweed taxa at each site. The dive sites were named SEM01 to SEM60 (the sites SEM35, SEM36, and SEM44 were not visited by Draisma). Photographs were made of the various macroalgae at each site and deposited in the WWF-Malaysia picture database. In addition to green, red, and brown macroalgae, the presence of the macroscopic “golden noodle alga” Chrysocystis fragilis Lobban, Honda and Chihara (Chrysophyceae) and that of seagrasses was also scored. An increasing number of blooms of C. fragilis has been observed on Pacific reefs in recent years. Abundance was not measured. Whether only a single individual of a species was found at a site or many, both were scored as present. However, note was taken when the frondose brown algal genera Dictyota, Lobophora, Padina, Sargassum, and Turbinaria were observed (subjectively) in high abundance at a site. The Reef Status Team estimated the percentage of algal cover along two transects at each site, but the team did not always visit the exact same locations as the Biodiversity Team and algal distributions may be very patchy. Some specimens were collected and preserved in 5% formalin in seawater in Whirl-Pak bags or jars and will later be dried and submitted to the University of Malaya 82 Seaweeds and Seagrasses Herbarium (KLU) in Kuala Lumpur. These herbarium vouchers can in a later stage be used to confirm or correct field identifications. Vouchers were numbered SGAD1012xxx, where xxx stands for 001, 002, 003, etc. (until 361). Before a specimen was transferred to formalin, a piece was cut off and preserved in either silica (Si) beads or 96% ethanol (EtOH). Si and EtOH samples can in the future be used for DNA extractions. Most turf algae were not scored because they can easily be overlooked and are unidentifiable in the field, but some were collected, e.g. Sphacelaria rigidula Kützing (SGAD1012112), and also some cyanophytes (e.g. SGAD1012111 and SGAD1012235). Crustose coralline algae were not scored either, with the exception of Lithophyllum-like morphologies. It must be emphasized that the taxon names in this report are based on field identifications and still need to be confirmed by examining the vouchers. Representative vouchers for each taxon are given in Table I. Many algae cannot be identified to the species level in the field and therefore several species were lumped under one taxon name, e.g. the genus Dictyota (which may also include representatives of the recently split-off genus Canistrocarpus), Padina, and Halimeda. In other cases Draisma is lacking the expertise to identify the alga in the field and a descriptive name is given, e.g., “green unbranched filament” or “red rubbery alga”. Taxonomic insights of macroalgae are still changing with more and more DNA sequence data becoming available. Some species can be morphological very plastic, but there are also species that cannot be distinguished from each other based on morphology alone. For example, Leliaert et al. (Molecular Phylogenetics and Evolution 53: 122-133, 2009) demonstrated that the enigmatic, sponge-associated Cladophoropsis vaucheriiformis (Areschoug) Papenfuss actually represents four different species based on DNA sequence data. Rohfritsch et al. (Biochemical Systematics and Ecology 35: 91-98, 2007) demonstrated that one of the morphotypes of Turbinaria conoides (J. Agardh) Kützing looks like Turbinaria ornata (Turner) J. Agardh. All known taxonomic uncertainties have been taken into consideration in the final version of a presence-absence taxon table. This table may later be analyzed in combination with environmental parameters that were measured by Aazani Mujahid during the Semporna Marine Ecological Expedition 2010. A preliminary cluster analysis of the presence-absence dataset was carried out using the MultiVariate Statistical Package (available from http://www.kovcomp.com/mvsp/?gclid= CNTp9Ku50asCFYMa6wodZBt6UQ). A minimum variance clustering procedure with squared euclidian distances was applied. Outcome In total, 361 collections were made. A detailed list of collections, observations and photographs can be obtained upon request from Stefano Draisma. Photographs taken at each site are also deposited in the WWF-Malaysia database. The taxa for which presence-absence data is collected are listed in Table I including the voucher numbers of collections, a list of some representative photographs, the SEM sites where they have been observed, and a reference to a distribution map. In the further discussion in this text Halimeda, Dictyota, Amphiroa are each treated as a single taxon, thus 94 taxa in total. Together these taxa may represent an estimated 130+ species, but this still needs to be confirmed after closer examination of the specimens. New records Phang et al. (2007) gives a checklist of the seaweeds of Malaysia (Seaweed Diversity in Malaysia. In Chua, Kirton and Saw [eds] Status of Biological Diversity in Malaysia and Threat Assessment of Plant Species in Malaysia. Forest Research Institute Malaysia. pp. 185210). From this list it can be concluded that the seaweed diversity of West-Malaysia is much 83 better known than that of East-Malaysia, unless Borneo is indeed less diverse than Peninsular Malaya. Phang et al. also published checklists of marine algae in 2008 and 2010 but these were limited to the South China Sea. Some of the algae collected during the SMEE expedition are not in any of the checklists by Phang et al. and can therefore be considered to be new records for Malaysia. Caulerpa filicoides Yamada and Caulerpa parvifolia Harvey are new records for Malaysia. The identification of C. filicoides has meanwhile been confirmed by DNA sequencing and its DNA sequence is identical to that of a C. filicoides specimen collected in the Berau delta (Indonesian Borneo), but differs substantially from two C. filicoides var. andamanensis W.R. Taylor specimens collected in Palau (Draisma, unpublished). A proposal is submitted to give separate species status to C. filicoides var. andamanensis (will then become Caulerpa andamanensis). The identification of the newly collected C. parvifolia specimen has also been confirmed by a DNA sequence, but it is known from Draisma’s unpublished sequence data set that also C. parvifolia represents two distinct species for which currently no diagnostic characters are known. The DNA sequence of the Caulerpa verticillata J. Agardh specimens from SEM18 and 30 differ substantially from those from SEM19 and 22, but no morphological differences are currently known. The type from SEM18 and 30 has also been found once in the Berau delta and once in the Philippines and is now for the first time recorded for Malaysia. More research is needed in order to decide whether to reinstate the name Caulerpa charoides for this type. Halimeda cylindracea Decaisne is one of the easier species to distinguish in the speciose genus Halimeda and was not recorded for Malaysia before and neither was the algal symbiont of the sponge Halichondria cartilaginea Esper, i.e., Cladophoropsis vaucheriiformis. The golden alga Chrysocystis fragilis is also a new record for Malaysia (but the Phang et al. checklists do not include heterokont algae other than the brown algae). It was observed in five locations around Semporna but nowhere did it form a bloom (i.e., covering several square meters). The red algae Dichotomaria marginata (Ellis and Solander) Lamarck, Gibsmithia hawaiiensis Doty, Ethelia sp., Mastophora spp., Predaea spp., Renouxia sp., and Vanvoorstia sp. are also new records for Malaysia and so are Euptilota articulata (J. Agardh) Schmitz and Asteromenia anastomosans (Weber-van bosse) Saunders et al. if these identifications are correct. The unidentified Jania sp. (Cheilosporum-like) from Sipadan is probably also a new record. Some of these new records were widely distributed in the research area (D. marginata, Ethelia sp., G. hawaiiensis, Predaea sp.), and it is not clearly understood why they have been overlooked in the past. The reason may be that earlier surveys were done by wading, dredging and snorkeling, but not by diving and thus deeper growing algae were overlooked. Distributions Taxon richness per site is indicated in Fig. 2. The highest number of taxa (30) was observed at SEM22 in the channel near Semporna town. However, other sites with a high number of taxa (>20) are only found on the outer reefs in the south (SEM09, 12-14), the north (SEM33, 45, 50, 54), and east (SEM26). Sites with no more than ten observed taxa were located central in the research area (SEM23, 37-38, 42, 56, 58), in the extreme southwest (SEM04-05) and around Sipadan (SEM59-60). Out of the 93 taxa, 56 were considered to be rare, because they were encountered at no more than five of the 57 visited sites. SEM22 has the highest number of rare taxa (11), followed by nearby SEM21 (9) and SEM20 (6) (Fig. 3). The northeastern reefs seem to have the lowest number rare taxa, but there is no clear pattern. The SMEE area was divided into subregions with 10-11 visited sites and the number of taxa per subregion was compared (Fig. 4). The southern barrier reef system was divided into a Southwestern (SW; SEM01-09, 20, indicated in red in Fig. 4) and a Southeastern (SE; SEM10-19, indicated in purple) subregion, each comprising ten sites. The Northeastern reefs (NE; in blue) included 84 SEM23-32 (10 sites), the Tun Sakaran Marine Park (TSMP; in green) included SEM33-46 (11 sites), and the Northwestern reefs (NW; in yellow) included SEM47-57 (11 sites). In the Channel between mainland Borneo and Bumbun island only three sites were visited (in white; SEM21-22, 58) and around the oceanic island Sipadan only two (in grey; SEM59-60) and comparison of these two regions with the others is therefore less relevant. The numbers of observed taxa in the five regions with 10-11 visited sites do not differ significantly (Fig. 4). The highest number of taxa (53) was observed in the SE subregion and the lowest number (43) in the TSMP. These regions also harbored respectively the highest (16) and lowest (9) number of rare taxa. SEM20 substantially pushes up the taxon richness of the SW subregion. If the SW region included SEM01-10 and the SE region SEM11-20, then the number of observed taxa (and rare taxa) per subregion would be, respectively, 42 (12) and 58 (21). If the Southern reefs are compared to the Northern reefs then the numbers are: SW+SE 66 (29), NW+NE 61 (24), and NW+TSMP 54 (19). Remarkably, only one taxon less than in the TSMP was observed at the three sites in the Semporna-Bumbun channel and the highest number of rare taxa was found here (18). The distribution of the 94 taxa is mapped in Figs 557. Ten of these 94 were found only in the Channel and nowhere else (Figs 17-18, 26, 30, 4748, 51). Eight taxa were only found in the SW (Figs 18, 40, 41, 47-48), and nine only in the SE (Figs 6, 17-18, 33, 40-41), five only in the NE (Figs 11, 18, 40, 48), four only in the NW (Figs 18, 33, 47), three only in the TSMP (Figs 18, 40, 47), and one only in Sipadan (Fig. 40). However, most of these taxa were found only once. Taxa that were restricted to a single subregion, but found more than once are Dictyosphaeria sp. (Fig. 18) and Renouxia sp. (Fig. 47) (both SW), Tolypiocladia sp. (Fig. 40) (SE), Stypopodium multipartitum (Suhr) Silva (Fig. 33) (NW), Enhalus acoroides (Linnaeus) Royle (Fig. 26), Gracilaria salicornia (C. Agardh) Dawson (Fig. 47), and Udotea orientalis Gepp and Gepp (Fig. 18) (all three Channel), and Jania sp. (former Cheilosporum) (Fig. 40) in Sipadan. Other taxa showed a wider distribution pattern, but some still limited. Avrainvillea sp. and Caulerpa racemosa var. lamourouxii were restricted to the Northern reefs (resp. Figs 5 and 15) and so was Cladophoropsis vaucheriiformis which, however, was also found in one Southern site (Fig. 20). Dictyopteris sp. was present in several Northern sites and only two sites in the SW (Fig. 28). Taxa with a distribution limited to the Southern reefs include Bornetella spp. (Fig. 9) and Turbinaria decurrens Bory de Saint-Vincent (Fig. 34). Taxa that were only encountered in the East were Caulerpa peltata J.V. Lamouroux (Fig. 13), Ceratodictyon spongiosum Zanardini (Fig. 39), and Portieria hornemannii (Lyngbye) P.C. Silva (Fig. 41). Taxa with a more or less central distribution are the seagrasses (Fig. 26), Acanthophora spicifera (M. Vahl) Børgesen (Fig. 35), Gracilaria/Halymenia sp. Z (Fig. 50), Spyridia filamentosa (Wulfen) Harvey (Fig. 40), Caulerpa sertularioides (S.G. Gmelin) M.A. Howe (Fig. 17), and Caulerpa verticillata J. Agardh which is absent in the North (Fig. 11). The distribution of Tydemania expeditionis Weber-van Bosse (Fig. 24) was limited to the outer reefs, whereas Chrysocystis fragilis (Fig. 27), Galaxaura rugosa (J.Ellis and Solander) J.V.Lamouroux (Fig. 45), Hypnea pannosa J. Agardh (Fig. 50), Lithophyllum sp. (Fig. 52), Titanophora spp. (Fig. 56), and Actinotrichia fragilis (Forsskål) Børgesen (Fig.36) showed a disjunct distribution being absent in the center of the research area, like Dictyopteris sp. Widely distributed taxa, but absent in the SW are Boodlea/Microdictyon/Phyllodictyon (Fig. 8), Caulerpa lentillifera J. Agardh (incl. C. microphysa [Weber-van Bosse] Feldmann) (Fig. 12), Caulerpa racemosa (Forsskål) J. Agardh (Fig. 14), Antithamnion(ella) (Fig. 38), and Chondrophycus/Laurencia (Fig. 42). Boodlea sp. (Fig. 7), Neomeris sp. (Fig. 22), Rhipidosiphon javensis Montagne (Fig. 23), and Predaea sp. (Fig. 54) are widely distributed but absent in the NW. Other taxa are distributed over the whole research area, but most of these taxa include multiple species (e.g., Halimeda spp., Dictyota spp., Padina spp.) and at the actual species level there may be a distribution pattern recognizable. It was noted that the brown algal taxa Sargassum spp. 85 (Fig. 30), Turbinaria spp. (Fig. 34), Dictyota spp. (Fig. 29), Lobophora spp. (Fig. 31), and Padina spp. (Fig. 32) showed a high abundance on the NW reefs and the former three taxa also in the SE. This might be an indication of disturbance. The nocturnal corallivore Crownof-thorns starfish (Acanthaster planci) has only been observed by Draisma in the NW (SEM48, 52 and 54), but only a few individuals. At most reefs Sargassum spp. occurred as small reduced plants (rosettes) and could not be identified. The collected specimens were identified as being S. aquifolium (Turner) C. Agardh (or S. binderi Sonder ex J. Agardh, the taxonomy is currently under debate) (SGAD1012108), S. ilicifolium (Turner) C. Agardh (S. cristaefolium C. Agardh which was recently synonymized) (SGAD1012126), S. oligocystum Montagne (SGAD1012127), and S. siliquosum J. Agardh (SGAD1012184 and with uncertainty SGAD1012315). Cluster analysis The result of the cluster analysis of the presence-absence dataset is shown in Fig. 58. The sampling sites are grouped into four clusters: A1, A2, B1, and B2. The geographical distribution of these clusters was mapped and is shown in Fig. 59. The sites of cluster A1 are mainly restricted to the Southwestern reefs. The sites of cluster B1 are almost exclusively found on the outer reefs, but not at oceanic Sipadan. The clusters A2 and B2 seem to reflect the inner reefs of the north and south, respectively. Other Expeditions In October 2003 Willem F. Prud’homme van Reine and Lisette de Senerpont Domis (both National Herbarium of the Netherlands – Leiden University) made seaweed collections in the nearby Indonesian Berau delta (http://www.repository.naturalis.nl/document/98097). They reported to have observed 233 macro-algal taxa (including varieties) and collected 189 taxa (470 collected specimens housed in Leiden). They did not collect presence-absence data for each visited location. It may seem rather trivial to make a preliminary comparison of the Semporna data and the Berau data with many taxa still unidentified, but it seems that at least the non-rare taxa around Semporna have also been found in the Berau delta. Eric Verheij and Prud’homme van Reine collected during a two years research period in the Spermonde Archipelago off Makassar (South Sulawesi) 223 taxa (published in Blumea 37: 385-510, 1993). Remarkably they did not list Dichotomaria marginata (and neither its synonym Galaxaura marginata). Prud’homme van Reine and Draisma made a presence-absence table for thirty sites in the Thousand Islands archipelago off Jakarta in September 2005 (also know as Kepulauan Seribu and not part of the Coral Triangle). Their presence-absence table included 78 taxa (60 genera; 60 genus level, 18 species level) and did not include eight collected seagrass species, but 32 green algal taxa (22 genera), 33 red algal taxa (27 genera), and 13 brown algal taxa (11 genera). Some of the taxa in the 2005 list were lumped in the SMEE2010 list. Thirty-four taxa were found at no more than four of the thirty sites and considered rare in the Thousand Islands. Taxa that were found at five or more sites in the Thousand islands, but were not found around Semporna were the green algae Anadyomene sp., Caulerpa brachypus Harvey, and Caulerpa cupressoides (West) C. Agardh, the red algae Liagora sp. and Asparagopsis taxiformis (Delile) Trevisan de Saint-Léon, and the brown algae Colpomenia sinuosa (Mertens ex Roth) Derbès and Solier, Hydroclathrus clathratus (C. Agardh) M.A.Howe, and Sirophysalis trinodis (Forskåll) Kützing. These taxa were observed though in the Berau delta, except for Asparagopsis taxiformis and Sirophysalis trinodis. Prud’homme van Reine and Draisma did not report Ethelia sp. for the Thousand islands, but this taxon was probably included in Peysonnelia spp. In total 684 specimens were collected at 39 locations in the Thousand Islands representing an estimated 150+ macroalgal species. In November/December 2007, Draisma collected 823 specimens at 68 sites in the 86 Raja Ampat archipelago (West Papua, Indonesia) representing an estimated 170+ macroalgal species (http://www.repository.naturalis.nl/document/124392). A presence-absence table was not made. In October/November 2009, Draisma collected 501 specimens at 40 sites around Ternate (North Moluccas, Indonesia) representing an estimated 120+ macroalgal species (http://www.repository.naturalis.nl/document/193936). A presence-absence table for 97 taxa was made for 38 sites which contained 33 green algal taxa, 4 seagrasses, 1 chrysophycean, 7 brown algal taxa and 52 red algal taxa. Fifty-two of the 97 taxa were found at no more than 4 sites. This list is most suited to compare with the SMEE 2010 presence-absent list, but none of the abundant taxa of each list is absent in the other list, except for Neurymenia fraxinifolia (Mertens ex Turner) J. Agardh which was found at 15 sites around Ternate but not around Semporna. There are some differences in abundance though. Some taxa were more frequently found around Semporna than around Ternate. For example, Sargassum was found at only one out of 38 sites around Ternate, but at fifteen out of 57 sites around Semporna. For other taxa these numbers are: Antithamnion(ella) 4 (out of 38) vs. 15 (out of 57), Ethelia 3 vs. 23, “red, soft, woolly blade” 2 vs. 16, Bryopsis sp. 7 vs. 21, and Chlorodesmis 1 vs. 29. Other taxa were more frequently found around Ternate: Ceratodictyon spongiosum 12 vs. 6, Dichotomaria marginata 33 vs. 19, Euptilota articulata 12 vs. 1, Hypnea pannosa 18 vs. 5, Mastophora pacifica 8 vs. 1, Mastophora rosea 9 vs. 1, Portieria hornemannii 21 vs. 2, Zellera tawallina 11 vs. 3, and Cladophoropsis vaucheriiformis 21 vs. 7. C. spongiosum and C. vaucheriiformis live in asssociation with a sponge, but they can also live without the sponge. The free-living stages may have a wider distribution, but were not observed/scored because they are inconspicuous. 87 Table I: Summary of results. A list of taxa arranged by Division/Class including the voucher numbers of preserved specimens (SGAD1012xxx), an incomplete list of representative images (IMG_xxxx), the SEM sites where the taxon has been observed, the total number of sites where the taxon has been observed (Obs.), and the figure (Fig.) in which the distribution of the taxon is mapped.

During SMEE 2010, five main reef areas (Southern, Northern, Tun Sakaran Marine Park, Northwest and Oceanic) containing 60 sites with 109 stations were surveyed. Using a modified Reef Check method which included underwater video transects and reef profiling the summary of results are: Substrate cover High damage from destructive fishing practices such as blast fishing/dynamite fishing could be seen via the high Rubble (RB) percentage at many sites An issue for concern as habitat loss for reef organisms. Fish density Overfishing and blast fishing could be seen via: Snapper low densities especially in Northern Reef area Parrotfish low densities at all sites Bumphead parrotfish very low densities except in Oceanic Reef area Humphead Wrasse absence except in Oceanic Reef area Barramundi Cod absence except in Northwest Reef area Sweetlips (Haemulidae) low densities at all sites - Of particular concern is the Grouper where it is found to be in low densities and in sizes of not more than 60 cm - Moray eel has low densities and in Northwest Reef area is absent at all stations surveyed - Butterflyfish has low densities but is still present at most sites Invertebrate density Over exploitation i.e. overfishing, curio and aquarium collection could be seen especially for: Banded coral shrimp low densities especially its absence at survey sites in Northwest and Oceanic Reef areas 123 - - Impacts - Triton shell low densities at all sites Sea cucumber low densities at all sites except Tun Sakaran Marine Park Reef area Collector urchin low densities except at some stations in Northern and Southern Reef areas Pencil urchin low densities especially its absence in Tun Sakaran Marine Park stations surveyed Lobster low densities at all sites except some stations in Southern Reef area Giant clam low densities at all sites except Tun Sakaran Marine Park Reef area nutrient pollution could be seen especially for: Northern, Tun Sakaran Marine Park and Southern Reef areas due to high densities of Diadema sea urchins Crown of Thorn Starfish (COTS) does not seem to be an issue for concern during the survey as it was at low density in all areas. Trash Impact levels are an issue for concern as they were high at most sites even within Tun Sakaran Marine Park Reef area - Coral disease and Coral bleaching percentages are found to be at low percentages. - Coral damage impacts are high in many sites, mainly from destructive fishing practices such as blast fishing/dynamite fishing except in Oceanic Reef area. RECOMMENDATION It is reminded that the methods used in this survey are designed for monitoring and annual surveys need to be done. Only when changes are detected for the biological indicators (and water quality) would the data be more precisely interpreted. At present we can only speculate when comparing stations, sites and reef areas. Long term monitoring data is essential. Nevertheless the criteria needed to be documented can be changed as needed though time. From the results of SMEE 2010, it is imperative to find ways to minimise coral physical damage, trash and over exploitation of marine organisms in the area. Even though conventional ways such as marine awareness, alternative livelihood for locals, tourism based economies run by locals, environmentally sound practices, proper solid waste disposal and low impact land development plans are always good to be used, novel ways which is suited and agreed upon by relevant stakeholders in the area has to be found. This can only be achieved through open and honest discussions between the stakeholders of Semporna PCA. 124 3.2 Materials and methods The Reef Status Team had eight SCUBA divers for each survey site. They were divided into three teams, either to survey transects at ‘Shallow’ or ‘Deep’ depth stations or reef profiling down to a depth of 25 m. The team members were: 1) Affendi Yang Amri (Universiti Malaya) – Team Leader 2) Nina Ho (WWF-Malaysia) – Co Team Leader 3) Kee Alfian Abd Adzis (Universiti Kebangsaan Malaysia) 4) Aazani Mujahid (Universiti Malaysia Sarawak) 5) Muhammed Ali Syed Hussein (Universiti Malaysia Sabah) 6) Nara Ahmad (Sabah Parks) 7) Munira Shaipudin Shah (Universiti Malaya) 8) Ken Kassem (WWF-Malaysia) 9) Angela Lim (WWF-Malaysia) 10) Carel Drijver (WWF-Netherlands) Reef status for each site was determined using a modified Reef Check which included underwater video transects and reef profiling. A modified Reef Check (Hodgson et al., 2006) was used at each study site. In general, for each survey site a 100 m transect each was deployed at 6 m depth ‘Shallow’ and 12m depth ‘Deep’ stations. Subsequently substrate percentage cover, fish and invertebrate density and impact surveys were done on four replicate 20m lengths with 5m breaks in between along the 100m transects concurrently with the underwater video transect and reef profiling. Underwater video footage of both 100m transects per site were taken and is currently being analysed based on the Line Intercept Transect (LIT) technique (English et al., 1997). Therefore the results from the underwater video are not included in this report. Reef profiling was done at each study site in which a pair of SCUBA divers descended from the end of their Reef Check transects down to a maximum of 25m depth. Then while slowly ascending they documented the benthic community structure on underwater paper attached to dive slates for every 5m depth. They essentially documented 5m x 5m quadrats while following the underwater profile ascending to the water surface. For each quadrat, firstly they documented the percentage of Biological and Non-Biological substrate and secondly they documented the percentage of Hard Coral growth-forms. Biological Substrate were: Hard Coral, Soft Coral, Dead Coral, Algae, Coralline Algae, Seagrass, Gorgonian Sea Fans, Sea Whips, Others Non Biological Substrate were: Rock, Rubble, Sand and Silt. Hard Coral growth-forms (Veron & Stafford-Smith, 2000) were: Branching, Massive, Table, Laminar, Foliaceous, Free living, Encrusting and Others. 125 Brief above water study site descriptions using Reef Check (Hodgson et al., 2006) and water quality parameters using a Hydrolab multiparameter probe were also taken but are not included in this report. During SMEE 2010 surveys from 29 November until 18 December 2010, five main reef areas containing 60 sites with 109 stations were surveyed (Table 1 & Figures 124). Nine sites have two transects at the same depth due to its flat seafloor topography without a distinct reef slope. The data of both transects e.g. Shallow 1 & Shallow 2 for Site 02: Second Reef were later combined for all nine sites. The two sites at Oceanic Reef area (Sipadan Island) only has one transect each at ‘Shallow’ depth as the island has a steep ‘drop off’ reef wall. © WWF-Malaysia / Eric Madeja 126 3.3 Results & Discussion There are 109 stations at 60 sites within 5 main reef areas surveyed (Table 1Table 1).

The criteria used is by the ASEAN-Australian Living Coastal Resources project (Chou et al., 1994), where >75% is ‘Excellent’, 50-75% is ‘Good’, 25-50% is ‘Fair’ and <25% is ‘Poor’. From the results (see Table 3-7 and graphs in this chapter), only 5 stations out of the 109 (5%) are found to be ‘Excellent’, 25 stations (23%) ‘Good’, 41 stations (38%) ‘Fair’ and 38 stations (35%) are at ‘Poor’ status. Only 38 stations (34.9%) surveyed has more than 30% Hard Coral (HC) cover. These 38 stations are listed in the following sub-chapters for each of the five main areas surveyed. These stations are over the average percentage, this is in view of Bruno & Selig (2007) report on 2003 surveys for West Indonesia which includes the SMEE 2010 study area as having an average of 29% coral cover. Their study also reported Indo-pacific reefs in 2003 having a coral cover average of only 22.1% and just 7 of 390 reefs surveyed that year had coral cover >60%. For further comparision Harborne et al. (2000) had estimated that the mean percent cover for islands on the east coast of Peninsular Malaysia to be at 42.2%. From all the substrate cover categories documented (Table 2Table 2) only Nutrient Indicator Algae (NIA), Rubble (RB) and Silt (SI) results are presented in detail due to present issues relevant to Semporna PCA reef areas. 134 Table 2: Substrate cover categories documented using the modified Reef Check method (Hodgson et al., 2006) Substrate Category Hard Coral (HC) Notes Scleractinian corals and includes fire coral (Millepora), blue coral (Heliopora) and organ pipe coral (Tubipora) because these are reef builders. Soft Coral (SC) Includes zoanthids Recently Killed Coral Corals that has died within the past year (RKC) Biological Indicator for Blast Fishing, Poison Fishing & Nutrient Pollution (if HC has low % cover) Blast Fishing, Poison Fishing & Nutrient Pollution (if RKC has high % cover) Nutrient Indicator Blooms of fleshy algae that may be responding to Nutrient Pollution Algae (NIA) high levels of nutrient input (if NIA has high % cover) Sponge (SP) All sponges (but no tunicates) Nutrient Pollution (if SP has high % cover) Rock (RC) Any hard substratum larger than 15 cm whether it is covered in e.g. turf or encrusting coralline algae, barnacles, oysters etc. Rubble (RB) Rocks between 0.5 and 15 cm diameter Physical damage i.e. Storms, Blast Fishing (if RB has high % cover) Sand (SD) Smaller than 0.5 cm Silt/Clay (SI) Sediment that remains in suspension if disturbed Run off from nearby land development (if SI has unusually high % cover) Others (OT) Other sessile organism including sea anemones, tunicates, gorgonians or non-living substrata 135 Southern Coral Reefs From Table 3 and graph for Southern Reefs, the status of the reefs surveyed is as follows: Table 3: Southern Reef area % live coral cover and reef status No. Site No. Station Name 1 S01 Mid Rock (Shallow) 2 S01 Mid Rock (Deep) 3 S02 Second Reef (Shallow) 4 S03 Hand Rock (Shallow) 5 S03 Hand Rock (Deep) 6 S04 Darby Bank (Deep) 7 S05 Alert Patches 2 (Deep) 8 S06 Alert Patches 3 (Deep) 9 S07 Erzherzog Reef (Shallow) 10 S07 Erzherzog Reef (Deep) 11 S08 Horn Reef (Shallow) 12 S08 Horn Reef (Deep) 13 S09 Ligitan Reef 1 S (Shallow) 14 S09 Ligitan Reef 1 S (Deep) 15 S09A Ligitan Reef 2 N (Shallow) 16 S10 Kapalai Island (Shallow) 17 S10 Kapalai Island (Deep) 18 S11 Cust Reef 1 S (Shallow) 19 S11 Cust Reef 1 S (Deep) 20 S12 Mabul Island (Shallow) 21 S12 Mabul Island (Deep) 22 S13 Ligitan Island 1 SW (Shallow) 23 S13 Ligitan Island 1 SW (Deep) 24 S14 Ligitan Island 2 SE (Shallow) 25 S14 Ligitan Island 2 SE (Deep) 26 S15 Ligitan Island 3 E (Shallow) 27 S15 Ligitan Island 3 E (Deep) 28 S16 Si Amil Island (Shallow) 29 S16 Si Amil Island (Deep) 30 S17 Denawan Island (Shallow) 31 S17 Denawan Island (Deep) 32 S18 Ligitan Island 4 W (Shallow) 33 S18 Ligitan Island 4 W (Deep) 34 S19 Cust Reef 2 N (Shallow) 35 S19 Cust Reef 2 N (Deep) 36 S20 Creach Reef (Shallow) 37 S20 Creach Reef (Deep) 38 S21 Sipanggau Island (Shallow) Text in red denotes Hard Coral >30% substrate cover Live Coral % Cover 18.1 14.4 39.7 73.1 80.0 55.0 41.3 34.4 65.0 62.5 50.0 31.3 35.0 39.4 56.3 20.6 12.5 66.3 77.5 15.0 11.9 46.3 21.9 11.9 19.4 15.0 8.8 26.3 18.1 21.9 18.8 81.3 56.3 59.4 49.4 48.1 5.6 25.6 Reef Status Poor Poor Fair Excellent Excellent Good Fair Fair Good Good Good Fair Fair Fair Good Poor Poor Good Excellent Poor Poor Fair Poor Poor Poor Poor Poor Fair Poor Poor Poor Excellent Good Good Fair Fair Poor Fair There are four stations (11%) that are ‘Excellent’, eight (21%) ‘Good’, eleven (29%) ‘Fair’ and fifteen (39%) ‘Poor’.

Rubble percentage is lower at Northwest and Oceanic Reef areas. This is an issue for concern as habitat loss for reef organisms. Fish density Signs of overfishing and blast fishing could be seen via: • Snapper low densities especially in Northern Reef area where blast fishing could be the main cause as the area has high Rubble (RB) percentage • Parrotfish low densities at all sites • Bumphead parrotfish very low densities except in Oceanic Reef area • Humphead Wrasse absence except in Oceanic Reef area • Barramundi Cod absence except in Northwest Reef area • Sweetlips (Haemulidae) low densities at all sites • Of particular concern is the Grouper where it is found to be in low densities and in sizes of not more than 60 cm. • Moray eel has low densities and in Northwest Reef area is absent at all stations surveyed. • Even though Butterflyfish has low densities but this group is still present at most sites. Invertebrate density Signs of over exploitation i.e. overfishing, curio and aquarium collection could be seen especially for: • Banded coral shrimp low densities especially its absence at survey sites in Northwest and Oceanic Reef areas • Triton shell low densities at all sites • Sea cucumber low densities at all sites except Tun Sakaran Marine Park Reef area • Collector urchin low densities except at some stations in Northern and Southern Reef areas • Pencil urchin low densities especially its absence in Tun Sakaran Marine Park stations surveyed • Lobster low densities at all sites except but some stations in Southern Reef area • Giant clam low densities at all sites except Tun Sakaran Marine Park Reef area Signs of nutrient pollution could be seen especially for: Northern, Tun Sakaran Marine Park and Southern Reef areas due to high densities of Diadema sea urchins COTs do not seem to be an issue for concern during the survey as it was at low density in all areas. 203 Impacts Trash Impact levels are an issue for concern as they were high at most sites even within Tun Sakaran Marine Park Reef area. Solid wastes (i.e plastics) were found to be at most sites except in Oceanic Reef area. Coral disease and Coral bleaching percentages are found to be at low percentages. Coral damage impacts are high in many sites, mainly from destructive fishing practices such as blast fishing/dynamite fishing except in Oceanic Reef area. The results above are only a snapshot and surveys at each site need to be repeated at regular intervals to document any changes to the reef. Any negative or positive changes need to be documented and further managed properly. Recommendation It is reminded that the methods used in this survey are designed for monitoring and annual surveys need to be done. Only when changes are detected for the biological indicators (and water quality) would the data be more precisely interpreted. At present we can only speculate when comparing stations, sites and reef areas. Long term monitoring data is essential. Nevertheless the criteria needed to be documented can be changed as needed though time. From the results of SMEE 2010, it is imperative to find ways to minimise coral physical damage, trash and over exploitation of marine organisms in the area. Even though conventional ways such as marine awareness, alternative livelihood for locals, tourism based economies run by locals, environmentally sound practices, proper solid waste disposal and low impact land development plans are always good to be used, novel ways which is suited and agreed upon by relevant stakeholders in the area has to be found. This can only be achieved through open and honest discussions between the stakeholders of Semporna PCA. 204 3.9 References Bruno, J. F., & Selig, E. R. (2007).

Communications One of the objectives of the expedition was for communications and outreach: Establish the value of the Semporna area for diving tourism in combination with coral reef conservation, based on its reef status, which includes information on species richness and the occurrence of rare and endemic species. The Semporna Priority Conservation Area is listed as globally-outstanding for its biodiversity in the Tri-national Conservation Plan of the Sulu-Sulawesi Marine Ecoregion (SSME). In addition, the SSME is one of the priority seascapes of the Coral Triangle Initiative which was signed by the Heads of State of the 6 Coral Triangle counties in 2009. A joint communications plan was established with NCB Naturalis for outreach in Netherlands and Malaysia.
