The Global Earth Observation Biodiversity Observation Network gathers together many of the world's leading providers of biodiversity data, information and decision-support services.

These organizations are collaborating through GEO BON to strengthen their individual capacities, make their respective data comparable and “interoperable”, develop the capacity of the producers and users of biodiversity information to engage more fully with GEO BON, and identify and address gaps and overlaps in biodiversity observations.

The links below will assist experts, decision makers and other users to access a wide range of biodiversity data and observations that are available through the portals of GEO BON participants. Additional links will be created as new portals come on-line.

• Global Biodiversity Information Facility (GBIF) – provides free and open access to millions of data records gathered from hundreds of data providers around the world.
• World Data Base on Protected Areas (WDPA) – contains crucial information from governments and organizations intended for ecological gap analysis, environmental impact analysis and private sector decision-making.
• The UNEP-WCMC Species Database – includes data on 75,720 animals and 88,763 plants of conservation interest, as well as 94,034 sub-species, stocks or synonyms.
• The IUCN Red List of Threatened Species™ – widely recognized as the most comprehensive, objective global approach for evaluating the conservation status of plant and animal species, including data for approximately 45,000 species.
• The Continuous Plankton Recorder Survey is the longest, most geographically extensive (pan Atlantic and other ocean basins) marine biological survey in the world with a unique data set of marine biodiversity.
