World distribution of coral reefs and mangroves

Mangrove distribution is taken from a variety of sources used in preparation of the World Mangrove Atlas, which was complied by the World Conservation Monitoring Centre as a joint project with the International Society for Mangrove Ecosystems and the International Tropical Timber Organization.

Coral reef distribution has been derived from a wide range of sources at various levels of scale and quality. In mast cases, the source maps plot emergent reef crest or shallow reef and reef flat areas. In order to show reef distribution on this world map, it has been necessary to scale up the area of reef that exists in most countries.
