Here we report the findings from the Marine Rapid Assessment Survey of the coral reefs of the northwest lagoon (Yandé to Koumac) of Nouvelle Calédonie. For the executive summary a brief overview on the Marine Rapid Assessment Program and on New Caledonia is presented first including general information on the inscription of the tropical lagoons and coral reefs of New Caledonia as a World Heritage Site. Further background information is presented for the two communes of Poum and Koumac that lie adjacent to the reef sites surveyed. This is followed by general background information on the survey sites and methods used to conduct the study. Finally, highlights of the results are given and we close with a discussion of conservation recommendations based on the findings.
