Figure Global biodiversity hotspots. The green areas and circled island groups have been identified as key biodiversity hotspots. These hotspots hold especially high numbers of species, yet their combined area of remaining habitat covers less than 2% of Earth's land surface. This map shows the global distribution of areas of high biodiversity. These areas tend to be concentrated in warm, wet climates capable of supporting many ecological niches. A significant number of the world's species may occur in these rapidly disappearing areas.
