The Lesser Sunda-Banda Seascape encompasses three functional sub-Seascapes: Lesser Sunda Seascape, Inner Banda Arc Seascape, and South and East Sulawesi Seascape. Fuctional seascape is defined as "areas within a wider ecoregion within which there is some geographical or ecological distinctiveness, but over a smaller area that maybe more suitable for the application of management measures such as MPA networks" (Green & Mous, 2008). These functional sub-seascapes provide a practical unit for marine conservation, including the design and implementation of networks of MPAs.
