A recent paper by Timothy Quimpo and colleagues, published in the Journal of the Marine Biological Association of the United Kingdom (JMBA), has revealed that coral reefs in the West Philippine Sea (WPS) have low abundance and diversity of corals and fish. Even the deeper areas of the reefs, the upper mesophotic coral ecosystems that are presumed to be buffered from disturbances, showed similar benthic and coral assemblage composition as the shallow water reefs, suggesting that both depths are vulnerable to disturbances.

The West Philippine Sea is a biodiversity hotspot and known source of fish and corals for reefs in surrounding countries. With the declining condition of WPS reefs, the abundance and diversity of fish and corals on other reefs could also be affected. This calls for regional efforts for better management and conservation of the area.

The research team, composed of geologists, oceanographers, and coral reef ecologists, was formed under the Geo-Physical Coral Mapping (GCM) project supported by the Department of Science and Technology - Philippine Council for Agriculture, Aquatic and Natural Resources Research and Development (DOST-PCAARRD). The team, headed by Dr. Fernando Siringan, Dr. Cesar Villanoy, and Dr. Patrick Cabaitan, aim to study upper mesophotic coral ecosystems throughout the Philippines.

The expeditions to the West Philippine Sea were funded and supported by the Department of Environment and Natural Resources-Biodiversity Management Bureau (DENR-BMB) and Department of Agriculture-Bureau of Fisheries and Aquatic Resources (DA-BFAR). Ongoing efforts of the University of the Philippines Marine Science Institute (UPMSI) and partners include understanding the diversity of other reef biota, including marine plants, fisheries, ocean productivity, and oceanographic processes in the WPS.
