The Coral Triangle, encompassing Indonesia, the Philippines and neighbouring countries, contains the highest density of marine species in the world, and exceptionally high numbers of endemic species (Asaad et al. 2018). Thus conserving its marine life is a priority for conserving all ocean biodiversity.

As part of his PhD, Irawan Asaad reviewed criteria used to designate protected areas internationally, and proposed that eight encompassed the aims of conservation: namely habitat rarity, vulnerability, importance for ecosystem integrity; habitat representivity within a network; presence of species that are threatened and/or endemic; sites important for species life-history (e.g., turtle nesting); and species richness (Asaad et al. 2017). Next he compiled all available biodiversity data, including species richness, fish endemicity, sea turtle migration and nesting areas, and coastal habitats to indicate the locations with highest biodiversity (Asaad et al. 2018).

Initial results were presented at the Esri Ocean GIS Forum (video of presentation here). The data can be freely explored online. This digital maps comprised of three different web-applications:

(1) Biodiversity Features provides comprehensive data on the region’s marine protected areas, biodiversity features, threats and environmental characteristics;

(2) Areas of Importance for Biodiversity Conservation provides spatial distributions of areas of high biodiversity conservation value; and

(3) Priority areas for Coral Triangle Marine Protected Area (MPA) Network Expansion.
