This document provides asimplified compilation of New Caledonia’s coastal ecosystem habitat maps based on data available from various sources , grouped into broad ecolog ical categories such as coral reefs, seagrass beds , and mang rove forests. Habitat categories can be refined based on data analyses needs. References to the orig i nal data sou rces are provided . This atlas was produced as part of the Track Changes project, financial ly supported by Labex Corail , Great Barrier Reef Foundation’s Resi l ient Reef i n itiative coordinated in New Caledon ia by Agence Neo-Caledonien ne de la Biodiversite , and Fonds Pacifique . Ce document procure une compilation simplifiee des cartes des habitats des ecosystemes coders de Nouvelle-Caledonie, issues de differentes sources disponibles, regroupees en grandes categories ecologiques telles que ies recifs coralliens, les herbiers de phanerogame et les forets de mangroves. Les categories d’habitats peuvent etre affinees selon les besoins en analyse des donnees. Les references des donnees sources sont procurees. Cet atlas a ete realise dans Ie cadre du projet Track Changes, soutenu financierement par Ie Labex Corail, I’initiative Resilient Reef de la Great Barrier Reef Foundation coordonnee en Nouvelle-Caledonie par l’Agence Neo-Caledonienne de la Biodiversite, et Ie Fonds Pacifique.
