The term '''megadiverse country''' refers to any one of a group of nations that harbor the majority of Earth's species and high numbers of [[endemic species]].

On 18 February 2002, the Ministers in charge of the Environment and the Delegates of [[Brazil]], [[China]], [[Colombia]], [[Costa Rica]], [[India]], [[Indonesia]], [[Kenya]], [[Mexico]], [[Peru]], the [[Philippines]], [[South Africa]] and [[Venezuela]] assembled in [[Cancún]], Mexico. These countries declared to set up a '''Group of Like-Minded Megadiverse Countries''' as a mechanism for consultation and cooperation so that their interests and priorities, related to the preservation and sustainable use of biological diversity, could be promoted. They also declared that they would call on those countries that had not become Parties to the [[Convention on Biological Diversity]], the [[Cartagena Protocol on Biosafety]], and the [[Kyoto Protocol]] on climate change to become parties to these agreements.

At the same time, they agreed to meet periodically, at the ministerial and expert levels, and decided that upon the conclusion of each annual Ministerial Meeting, the next rotating host country would take on the role of Secretary of the group, to ensure its continuity, the further development of cooperation among these countries, and to reach the various agreements and objectives.<ref>{{cite web|url=http://www.unido.org/file-storage/download?file_id=11803|title=UNIDO – United Nations Industrial Development Organization|publisher=}}</ref> Later, in 2010, Guatemala and Iran were also included in the list.<ref>{{cite web|url=http://www.biodiversidad.gob.mx/planeta/internacional/paises_megadiversos.html|title=Plataforma de monitoreo de las actividades de implementación de la Estratgeia Nacional sobre Especies Invasoras (Previene) – Biodiversidad Mexicana – Comisión Nacional para el Conocimiento y Uso de la Biodiversidad|first=|last=CONABIO|publisher=}}</ref>

The 17 countries identified as megadiverse by Conservation International

A megadiverse country is one of a group of nations that harbours the majority of Earth's species and high numbers of endemic species. Conservation International identified 17 megadiverse countries in 1998,[1][2] all of which are located at least partially in tropical or subtropical regions.

Megadiversity means exhibiting great biodiversity. The main criterion for megadiverse countries is endemism at the level of species, genera and families. A megadiverse country must have at least 5,000 species of endemic plants and must border marine ecosystems.
