Dataset on coral reefs comes from the UNEP-WCMC Biodiversity Map Library: Global Coral Reef Distribution. This dataset was compiled by digitizing coral reef locations from a large number of sources and maps. This global dataset is replaced with high resolution coral reef coverage from the Millennium Coral Reef Mapping Project where available.

The Millennium Coral Reef Mapping Project (IMaRS, Univ. South Florida; P.I.: Dr. Serge Andréfouët), classifies and maps coral reef structures worldwide using Landsat data. This project is funded by NASA, and is an international partnership between numerous organizations and experts. Shown here are preliminary datasets of selected areas which have been classified into coral reef areas. The Millennium Coral Reef Mapping Project uses a large number of reef types and subtypes in their classification efforts. In this application in ReefBase, those types have been aggretated into fewer and simpler summaries.

This data is provided by the UNEP-WCMC Biodiversity Map Library: Global Mangrove Distribution and The Nature Conservancy. Mangrove distribution was taken from a variety of sources used to compile the World Mangrove Atlas, which was prepared by the World Conservation Monitoring Centre as a joint project with the International Society for Mangrove Ecosystems and the International Tropical Timber Organization.

The seagrass dataset has been compiled by UNEP-WCMC in collaboration with Dr Frederick T. Short, University of New Hampshire, USA to show the global distribution of seagrass species. This dataset has been created from multiple sources and was used in the creation of the "World Atlas of Seagrasses" (2003). This polygon feature dataset is an update of the data used in the Atlas and is a unique data holding about the state of the world's seagrasses. For a complete overview of global seagrass distribution this dataset should be displayed together with the associated point dataset.

All protected areas are represented by a symbol indicating the approximate central point. However, for a number of protected areas, polygons are being displayed as well, indicating the extent of those protected areas.

An overlay of potential nesting beaches, internesting areas, and migratory patterns of Leatherback sea turtles (Dermochelys coriacea) and other species in Indonesia. The boundaries were delineated based on expert judgment in 2019. MMAF also recorded nesting beacheas, specially in Java, Bali, and Papua region.

Coral bleaching is a major phenomenon affecting coral reefs around the world. An initial database of bleaching observations was compiled by UNEP-WCMC using a variety of sources. This database has been expanded by ReefBase at the The WorldFish Center, using information from the ReefBase database, the Great Barrier Reef Marine Park Authority (GBRMPA), the CoralList, and other sources of information. This dataset also includes observations indicating no bleaching.

Data on occurrences of coral diseases originated from the Global Coral Disease database, by UNEP-WCMC. This database was compiled using disease observations and has been expanded by ReefBase using information from a variety of sources.
