NDF WORKSHOP CASE STUDIES WG 9 – Aquatic Invertebrates CASE STUDY 5 Stony corals Country – INDONESIA Original language – English EVALUATION OF NON-DETRIMENT FINDING FOR TRADE IN STONY CORALS FROM INDONESIA.

1.1. Scientific and common names Species considered in this cases study are known by the common name “stony coral”. This included the order Scleractinia, which is represen-ted by 17 families, 109 genera and more than 800 species of corals. Indonesia is located within the center of biodiversity with some 590 described species of coral, belonging to 82 genera (Veron, 2002; Best et al, 1989; Hoeksema, 2006; Wallace et.al. 2000). Because of the high diversity of corals, and ongoing taxonomic revisions, it is not possible to name all coral species, let alone to include the synonymy, since many coral taxonomists are still in disagreement. Only a portion of the stony corals found in Indonesian waters are currently being extracted for international trade. These are listed in Table 1. (Note: all table and figures see appendix 1). Beside scleractinian coral, two other anthozo-an corals, Heliopora (blue coral) and Tubipora (organ pipe coral) are listed There is also one group of hydrozoan corals in two families, the Stylasteriidae (Stylaster and Distichopora spp.) and Milleporidae (Milleopra; fire coral). 1.2. Distribution Indonesia has the largest and most extensive coral reefs ecosystem in the world. These are estimated to cover some 87,500 square km or 14 % of the total area of corals reefs found worldwide. Coral reef
