megadiversity
Exceptional biological variety
Megadiversity describes regions or countries with exceptionally high concentrations of species, particularly those found nowhere else.
Seventeen nations hold this designation, including Brazil, Indonesia, and Australia, which together contain most of Earth's biodiversity.
The term appears in conservation and environmental policy: Megadiversity hotspots require urgent protection.
A megadiverse country faces particular responsibility for preserving global biological heritage.
